On a friday night in an industrial loft in Brooklyn, the engineer finally completed his work. Ten years of working in secret, ten years of a boring desk job at a medical engineering firm to support it, pouring all of his available funds into his own equipment… and it all boiled down to a tiny drop of liquid in a tiny glass vial, filled with nanomachines too small to see. A monumental achievement in engineering: nanobots that would cure all known sexually transmitted diseases (and quite a few other diseases), and take excess human fat and cholesterol to break them down to power themselves, make more nanobots, and make… other things.
But, he didn’t care about the technological achievement of the nanobots, or the medical achievement of the cures for diseases and obesity, this was about revenge. Revenge for the gaybashing 15 years ago that left him in months of painful recovery. Revenge for all the verbal abuse he’d received from straight men over the years. Revenge for the legal discrimination against his civil rights. Tonight, he would have his revenge, the discrimination and beatings would head toward their end, and the world would be changed forever…
But enough gloating, it was finally time to put the plan into action. He placed one of the vials in a padded case and pocketed it, grabbed his gym bag and stuffed in a pair of loose-fitting jeans, a box of cards he had pre-printed with his email address, and as an afterthought, a couple fresh bottles of poppers… hell, it’s the big night, might as well enjoy it, right? Pulling on his coat, he was out the door, on his way to a sex club to change human history.
In a private room at a sex club in Manhattan the engineer disrobed, folding his clothes neatly and placing them aside. He took out the case with the vial, opened it, uncapped the vial, and before he could change his mind he poured the drop of liquid into his mouth. There would be no going back.
He reclined on the narrow mattress the club put in its rooms and waited. He had estimated that it would take about half an hour before the nanobots were in full swing. While he waited and tried to relax, they had entered his blood stream and spread throughout the body in minutes, found the fat in the small paunch he’d developed from spending too many hours in front of a computer instead of in the gym, and started breaking it down for raw materials. Their numbers increased rapidly, and in minutes they were spreading out with raw materials to start making… changes.
He first knew that the changes had begun when he started to feel tingling sensations in his cock and his ass. They were being restructured, another function of the nanobots. He had wondered if it would hurt, but he had gotten the functions that dulled the pain nerves while the work was going on correct, so instead it felt quite pleasurable. As his cock hardened slightly from the feeling he began to stroke it, settling back to enjoy the sensations. His five inch cock had been his favorite body part for a long time, but now he’d be seeing more of it. The changes were subtle at first, but as the number of nanobots multiplied, building on all the small bits of extra fat throughout his body, they reached the critical mass where they could start making changes much more quickly. Enjoying his slow stroking, he looked down to see his cock had reached a full inch longer than it had ever been. Soon it was seven inches, and slightly thicker than he was used to. 8… 9… the changes were starting to slow down now, as his now massive cock reached ten, and finally eleven inches. For now, the growth apparently stopped.
God, it felt good. Stroking had never been like this before, with his hand sliding slowly up and down his massive tool. He could also tell some of the more subtle changes had taken place… the nanobots had stimulated production of excess testosterone and were ramping up his sex drive hugely so the 40 year old researcher was at least as horny as the most hormonal 18 year old. Of course, being already at a sex club when this happened was all part of the plan, so he pulled a towel around his waist, grabbed a bottle of poppers, and headed out to the steam room.
At the steeam room he left the towel on a hook outside the door, slipped around the guys sucking and fucking in the middle of the room, and onto a bench. As he enjoyed the warmth and began to sweat, some nanobots were released in his sweat onto the surface of his skin, onto the bench, and in the air. His newly ten inch, rock hard cock gained the attention of the other men quickly, the excess pheremones his body was producing thanks to changes in his skin helped make them even hornier, and he selected several guys at random to service him. The two were quickly on their knees in front of him, licking and sucking on his cock and balls. He’d never had it this easy getting guys before, and he was *really* enjoying the oral attention. He hadn’t really considered before that a bigger cock means more surface area to cause pleasure, but wow was it great! He was glad he’d always been good at holding himself back from cumming, and got to moan and enjoy being sucked hard for a good 15 minutes before cumming in the guy’s mouth. The guy had already been exposed to nanobots from the researcher’s precum and sweat, but the cum had a good strong shot of nanobots in it, helping give the bots in his system a jump start as they were absorbed in his mouth and throat.
The guys who had been sucking smiled and got up to look for new playmates as the engineer took a moment to breathe after cumming… but with his semen production now on overdrive thanks to more nanobot changes, he was hard again in perhaps a minute. He was certainly a center of attention as he strolled to the door to get his towel and head to the orgy room. Behind him in the steam room, all of the men were starting to feel pleasant tinglings in their cocks and asses, and the group fucking and sucking reached a new frenzy.
In the drier atmosphere of the orgy room the engineer’s sweat slowly evaporated, spreading nanobots throughout the room for the other men to breathe in. Unsurprisingly, his huge cock was hugely popular, and with his newly quick recovery time, he could get sucked off by guy after guy and just clean off his cock with his towel and move on to the next. Hot sex always attracts onlookers in an orgy, and as the engineer was eager to spread the nanobots around he invited onlookers to participate. Soon he had one guy sucking his cock, another on his balls, one on each nipple, one on each armpit, and one last guy fucking him. His new ass made being fucked feel even better than it had before and could take any cock, so soon all he could do was scream with pleasure as he allowed the 7 guys working his body to support him and try to drain his seemingly inexhaustable supply of cum. He put the poppers to his nose, snorted himself good and stupid, and surrendered his mind to being sex-crazed for hours.
Within an hour or so changes were becoming apparent across the club, as everyone’s cocks filled out to between 9 and 11 inches, their sex drives went wild, and their sexual appetites became insatiable. Of course the guys were stunned by the changes, but too overpowered by their pumping hormones to care, they went at it like animals. Even the jaded sex clubs of New York had never before seen the like of the frantic nonstop fucking that took place that night, quickly drawing in every patron of the club, and soon attracting most of the staff members to take a break to go play with some of the really stunning cocks they saw on the guys wandering the halls. The men stayed, and fucked like animals, until well past dawn, eventually trickling out in pairs and small groups to go find food, and then go home to have more frantic, wild sex.
In the club, the nanobots had spread on moisture in the air and by physical contact. They were all over the walls, the floors, and the benches. The next day’s crowd of patrons would soon find themselves having much the same experience.
Saturday night when New York’s gay bars filled up, there were a fair number of men who had recently lost weight and had enticingly big baskets in their jeans, all very horny and eager to hook up for sex right away when asked.
Sunday morning a couple who had been at the club saturday evening got on a plane, feeling surprisingly awake even though they’d been fucking like animals all night after the delightful experience of suddenly growing enormous cocks. They had been planning this vacation to Amsterdam for months, and were really looking forward to lots of play in its fabled gay scene. Amsterdam had no idea what it was in for.
The nanobots were spreading, and the conversion of humanity had begun.
The electrician returned to work on monday feeling relaxed and strangely refreshed after a crazed weekend of fucking with a guy he met at the bar on saturday. He was still feeling randy, and his suddenly—and delightfully—enlarged cock stayed semi-hard as he admired the muscled bodies of his construction-worker coworkers as they began the day’s work.
It was hot inside the incomplete new office building, a hot summer day with no air conditioning installed yet, and many of the men worked shirtless, sweat glistening on their skin. Quickly the whole place smelled of sweaty men, and the air was thick with the moisture of sweat… and nanobots. It seemed like just another workday on the surface, and no one noticed the men occasionally shifting around to adjust themselves to more comfortably position their cocks, which seemed for some reason to feel nice and tingly, despite that their underwear seemed strangely tight.
An few hours later the electrician and a flooring installer both happened to head to the first floor mens room, which had already been completed, at almost the same time. The electrician arrived to find the room empty, and sighed with relief as he made his way to a urinal and whipped out his massive cock to give himself some relief from the increasingly insistent sexual urge caused by his new sex drive. As he was starting to stroke it good and hard, with his eyes closed and his head thrown back, the flooring installer walked in.
Seeing a shirtless man jerking off at a urinal would normally have repulsed the flooring installer, but he found himself strangely drawn to the huge, throbbing cock the electrician was stroking… and the electrician opened his eyes and looked around suddenly when he abruptly felt the flooring installer’s tongue on the head of his big hard cock.
An hour later at noon the contractor finally noticed half the crew seemed to be missing but figured they probably went to lunch, so he invited a couple of guys to join him to go grab a bite at the sandwich shop next door. On their way out of the building someone needed to hit the mens room, and the contractor thought it would be a good idea anyway, and the other guys followed.
They walked into the mens room to find a full blown orgy going on… discarded clothes strewn about the floor, and eight or ten huge-dicked guys fucking and sucking frantically near the sinks. Stunned, he opened his mouth to shout his outrage at them but… wow, the sheet rock guy’s arms looked really… attractive… and the carpenter’s chest looked really hot as he piston fucked the electrician… and so the contractor and his buddies found themselves adding their clothes to the pile on the floor and wandering into the enticing action.
In the middle of the group of thrusting bodies, the electrician was in bliss from the nine inch cock pummeling his prostate. He’d already cum five or six times in the mouth of the tile guy sucking his cock, after having fucked the flooring installer wildly… but the semen kept building back up in him and his cock’s time to get hard again was under a minute, so the pleasure was too intense for him to stop. He sucked passionately at the ten inch cock being rammed into his throat and moaned with pleasure as he felt another warm load of cum being deposited in his ass, and it pushed him over the edge into his eigth orgasm of the morning.
The contractor, meanwhile, was feeling horrified at what he was doing but couldn’t seem to stop himself from giving in to the overpowering urge to fuck the sheet rock guy. As if in a trance he shoved his cock into the guy’s eagerly offered ass and shot his load almost at once as he felt the hot soft tightness of a man’s ass on his cock for the first time… but before he could bring himself under control he found himself getting hard again and starting to thrust in and out and fuck the ass hard. He knew this was disgusting, this was immoral, he had to stop it, he… God, it had never been this good with his wife. Why had he never thought of this before? He felt a cock begin to press itself into his ass and realized not much work was going to get done on the building that afternoon.
Across New York these scenes played out as men who had been modified by the nanobots returned to work. The nanobots spread out to do their work on their coworkers, turning everyone quite firmly homosexual, enhancing everyone’s sex drive to make them have a hard time controlling their raging libidos, slowly starting to break down everyone’s weight problems, and giving all the men really big cocks. However, it wasn’t just coworkers. Every nanobot carrier who took the subway to work spread nanobots to everyone they had brushed past in the station, and exhaled more on everyone near them in the train car. These people in turn passed on the nanobots to their coworkers, people they brushed against on the streets, everyone in the restaurants they had lunch at… it was spreading like wildfire.
In Amsterdam the couple who had gone on vacation had spread the nanobots through the air to everyone on the plane, and all those people spread the nanobots throughout the country. The couple also made wild use of the city’s gay sex spots, spreading more to men who then went home from their own vacations, spreading nanobots throughout the world. Within days, it was spreading everywhere.
Symptoms of the nanobot induced changes started showing up in the news within a day or two. There was a temporary dip in productivity, which economic analysts didn’t yet know enough to attribute to vast numbers of people having wild gay sex while they learned to keep their new libido under control long enough to get a day’s work done.
Psychologists and psychiatrists experienced a sudden influx of new patients seeking counseling about their sudden newfound homosexuality and huge sexual appetites. Of course the doctors got the nanobots from the first patient to sit there for an hour’s session and breathe at them, leaving the poor doctors hard pressed to control their desires for their patients.
Within a week the divorce rate skyrocketed from formerly heterosexual couples who had suddenly lost interest in each other, or had caught each other cheating with coworkers and friends of their own genders. This finally brought it to the public’s attentiont that something big was going on, that it wasn’t just them who was suddenly and inexplicably desperate for gay sex. The news finally broke about definite symptoms… for women, a loss of interest in men and an uptake in desire to be with other women, and for men, tingling feelings in the “privates” followed almost immediately by unexpected growth of “the male member”, conversion to exclusive homosexuality, and enormous sex drive.
Public panic ensued as it became clear that the “disease” was spread by simple physical contact or even by air exhaled by a carrier. A run on filter masks at the hardware store only spread it further as of course sooner or later someone who already had the nanobots would pass through the store and unknowingly leave some behind.
As a few men turned up who seemed unaffected by the nanobots despite everyone around them being converted, it became apparent that the “gay-inducing-disease”, or “GID” as it was rapidly becoming known, required body fat when all of the “immune” men were skinny as a rake. When word got out fundamentalist christians everywhere went on crash diets, not knowing it was too late if they weren’t already absurdly lean. A few of the “immune”, perhaps from frustration with their spouse having already converted and lost interest in them, or perhaps from jealousy at the frequent wild sex their acquaintences were obviously enjoying or the enormous cocks their friends had grown, decided “if you can’t beat ’em, join ’em” and started overeating. They began to convert in days, although it took them slightly longer than for others to grow in their new and improved private parts.
Fat people turned out to spread GID abnormally strongly to everyone around them… since, of course, the nanobots had more raw materials to work with. The fat people in question were more delighted by their rapid weight loss, and of course they were getting plenty of exercise through suddenly frequent sex.
Men who had already converted found themselves enjoying extra large meals to give their body the energy they needed for the frequent fucking, and the raw materials to make all the extra semen. But, thanks to the GID nanobots, they continued slimming away any fat.
Sales of home video products dropped sharply. Sales of lubricants and condoms rose sharply, as most of the modified men had not yet realized either that they were immune to sexually transmitted diseases or that their asses were now self-lubricating. Sex clubs were doing business like they had never imagined. In the evenings secluded spots in parks filled up with horny men eager to pull off their clothes for hours and hours of frantic fucking… many finding themselves unable to find their clothes in the mess afterward and strolling home nude, usually with a playmate or two. Police initially didn’t know whether to try to arrest everyone for public indecency or to give in to reality and accept that there were too many to cope with, but it soon became apparent that when police tried mass arrests the arrested men would only end up fucking like animals in the holding cells, and soon enough the very cops who had arrested them would give up and let them free so they could join in the fun.
Mostly it was only the men who had already been modified by the nanobots who started to notice that they seemed quite able to do without sleep for days and would still feel relaxed and refreshed every morning if they spent the whole night having sex, and they were a bit too busy having fun to concern themselves with notifying the press.
In his loft in Brooklyn, the engineer finished reading the latest news report about his creation. The network had had to get a temporary evening news anchorperson after the previous one had gotten the nanobots and become a bit too involved with the weather man to continue reporting for a few days. Scientists hadn’t figured out that it was nanobots, not a disease, causing GID, but it would probably happen in a few days after doctors stopped fucking long enough to look in the electron microscope for a while. He wasn’t concerned. Phase 2 was going splendidly, and soon almost everyone on earth would be converted to homosexuality. The changes were permanent: even in the unlikely event doctors and scientists came up with a way to eliminate the nanobots from someone’s body, they structural changes the nanobots had made to the anatomy and brain structures of their carrier could not be reversed, and anyway the person would almost immediately pick up more nanobots. No, soon the whole world would be gay, he thought as he turned off the computer screen and turned to leave his office to return to the orgy in his living room.
As he opened a couple bottles of poppers and placed them on an end table he thought happily of what would be coming soon in Phase 3, only a few weeks away. He left several bottles open on the table to spread their fumes through the room, and took another with him to play with as he wandered into the group and his huge new cock once again grew hard. As he felt a hot wet mouth slide onto it and a rock hard cock probing at his ass, he put the bottle to his nose and snorted in a deep hit. As he felt his blood start to throb in his head, and a pleasant feeling of pressure set in on his mind, he felt happy as he surrendered himself to another night of mindless fucking.
Phase 3 was coming, and the world had no way to stop it.
The President of the United states denounced the sudden “trend” of homosexuality as “immoral” and proclaimed people with GID as “perverts”, railing against them in nightly televised speeches and calling for them to be quarantined in remote camps… until it was leaked that during his thursday evening speech from the oval office, he had a male intern hidden under his desk sucking him off. After that political statements on the subject grew quiet for a time as the world considered the implications of what was happening.
Children seemed unaffected by GID until they reached puberty. In grammar schools life went on much as usual, but when a boy reached puberty, within a day or two he would quite abruptly grow an enlarged cock and an out-of-control sex drive. High schools had to begin to re-evaluate their curriculum as every school day seemed to drift into the pattern of all the boys disappearing from classes after a few hours to engage in frantic, animal sex in the rest rooms or locker rooms. Universities seemed to fare slightly better as the students usually had a couple hours to nip off and fuck each other between classes, although homework was rather suffering.
Phase 3 began about a month after Phase 1 was in full swing, by which time a large majority of the human population of Earth had undergone Phase 1 conversion to homosexuality and male genital enhancement. The changes weren’t so fast this time… in many average people the GID nanobots had used quite a bit of the person’s fat reserves as raw material to build many more nanobots to spread the changes through the population, so there wasn’t as much raw material available for new changes this time.
At first men who had lost weight just noticed that over a week or two their skin started to tone up so they no longer had that slightly-flabby look of someone who had recently lost 5 or 10 pounds. But, in the weeks after that they started to gain a bit of muscle. Most guys initially dismissed it as the muscle they’d always had starting to show better… some thought it was just from all the exercise they’d been getting from sex… but within a month of Phase 3 starting all the Converted guys were starting to show powerful-looking arms and defined six-pack chests, as well as muscular everything-else. Not everyone was the same… some built up faster than others because they were eating enough to generate body fat to fuel the nanobots, but also the men were really filling out to a natural potential, rather than an arbitrary level of muscle defined by the Engineer. So, while men were all becoming attractively muscular, there was still a lot of natural variation, from tall lean guys to barrel chested muscle bears to slim wiry types. Some guys reached their maximum potential right away, while others kept growing…
The computer programmer fumbled with the keys to his apartment in his eagerness to get the door open and drag in the two hunks he’d met on the street on the way home from the office. Getting fucked by the guy from HR in the conference room during lunch and an impromptu afternoon quickie sex break in the mens room had been hot, but these guys were something else. They’d clearly just met as well when he came across them and were just starting to discuss where to go fuck when they laid eyes on him and called out to invite him to play. He lived closest.
They’d managed to control themselves just long enough to get inside and shut the door before starting to pull their clothes off of each other. The tall black haired hunk had shoulders as wide as an axe handle, a body like the letter V, arms that hung like a gorilla because there was so much muscle in his pecs they didn’t allow him to put his arms quite to his sides, a thick carpet of soft black fur across his upper chest, and a real thick twelve incher tool that was starting to harden as he undressed. Meanwhile blond boy was his polar opposite, slim and boyish at 5’2 and 110 pounds of nothing but bone and wiry muscle, he looked like a skinny but well defined 12 year old even though his college ID showed him to be 19. (Black hair guy had been concerned.) His ten inch cock jutted out massively in contrast to his slim frame, already hard when he unleashed it from his strained shorts. The programmer was a good halfway between the two… lanky but with definition from his GID-induced muscles, a strong face, a soft sprinkling of light brown hair on his chest leading to his happy trail, big powerful arms, and an extra thick ten inch cock coming to attention for the other guys.
Blond boy slipped his arms around the programmer and began to hump against his body and cock even before they’d gotten out of the front hall. The programmer grabbed him under the arms and picked him up, allowing blond boy to wrap his legs around the programmer and hump away even as he was being carried into the bedroom. Placing him on the bed the programmer climbed on top, to find himself covered by black, already guiding his thick veiny cock to programmer’s waiting hole.
Programmer felt so good as he was being entered. He felt so complete and fulfilled to have a huge cock buried in him, he’d never felt this good when he’d been straight. He also loved the feeling of a big man covering him as he now felt black’s massive furry chest pressed to his back. His own cock felt really good with blond boy’s leg rubbing in his crotch as blond continued humping and kissing him passionately. He felt soooo good, he wanted this big man in his ass and this slim boy in his arms forever… and with the thought he shot his load between blond boy’s legs. He had of course had a couple months to adjust to the idea that he had almost immediate recovery so he just kept humping blond boy and allowed himself to feel the unstoppable prostate pounding of Black in his ass.
Soon Blond, and then Black, also shot loads, and abruptly there was an unexpected pause in the pace of the sex. “I don’t know about you guys,” Black growled, “but I was gay before GID, and we know a few things about mansex. Try this.” And with that, in his hand he revealed a small brown bottle. Programmer and blond boy didn’t recognize poppers having never seen them before, but Black opened the bottle and placed it under blond boy’s nose and told him “snort it,” and blond boy knew when to submit to the alpha male so he inhaled. Programmer, face to face with blond boy, was startled and delighted as blond boy looked surprised, then dazed, and a vacant, stupid smile took over his flushed face as he clutched onto Programmer tighter and started to hump even faster and harder.
“How long does it last?” Programmer asked.
“Well, it used to last two, perhaps three minutes,” Black explained, “and it was a big head rush, but since GID it lasts for an hour, and you also get real stupid and mindless while it’s happening. You just become a sex-crazed animal, and with occasional snorts—which you’re almost certain to take in your stupor—you can stay that way for 8 hours before you need a break.”
Programmer looked down into the dazed and happy face of blond boy, now wrapping his legs around Programmer and Black as he squirmed to move his ass onto Programmer’s cock. He wondered what it might feel like to be high, stupid, mindless, and fuck like an animal. Before he could ponder it further Black growled “time to get stupid boy,” in his ear and shoved the bottle under his nose just as he was inhaling. As he felt the blood rush to his head and an odd but pleasant pressure descend inside his skull, his last thought was “oh my” before his mind slipped away and his body started fucking blond boy hard in frantic rut.
Black looke down happily at his two playmates, enjoying the feeling of now-stupid programmer bucking back and forth onto his cock. Time to join the stupid club. Bringing the bottle to his nose, he inhaled a deep, hard snort, and placed it on the night table, open so the fumes would keep them all going.
In moments there was no more thought in the apartment, just three mindless animals in rut, pounding each others asses with their cocks for the night.
Representatives of the United States military services officially appealed to the congress and senate to repeal laws banning homosexuality in the ranks, which seemed only sensible now that practically everyone in the services was now gay. Requests for funding for substantial additional recruiting were denied, however, when it became clear that mostly they just wanted more members for the frequent barracks orgies.
The porn industry had a brief lot of fun making piles of new gay videos and magazines before it became clear that no one was buying, since everyone was too busy actually having sex to bother looking at pictures of it. The sex toy industry, on the other hand, was having a huge boom as soon as they could bring themselves to stop using their own products long enough to make more for sale.
In the morning the programmer finally started to come down from his last hit of poppers and return to conscious thought. The night had been a wild blur of cocks, asses, Black’s muscle, blond boy in his arms, and an ecstacy of orgasm after orgasm. There was cum everywhere. He was held tight in Black’s arms with Black’s softening but still huge cock lodged in his ass, and blond boy was clamped tightly to his chest, dozing lightly. The programmer closed his eyes to enjoy the moment. Soon he’d get up and make a huge breakfast of sausage and eggs. It was saturday, and with these two in his bed he knew he had a hell of a weekend in store.
Fundamentalists screamed for the preservation of “traditional values” and urged everyone with GID to abstain from sex. They started remote colonies in the countryside of people who pledged thelselves to celibacy and christianity, but the colonies failed after investigative reporters found that all the men were sneaking out to fuck in the woods after dark instead of sleeping. Their appeals for public support mostly fell on deaf ears, because despite the massive logistical problems of practically every married couple heading for divorce, most everone was too happy with their new sex life and their new body to want to complain.
High schools, out of necessity, instituted short breaks for sex four times a day and replaced physical education with a full hour of sex. It didn’t bring a halt to students skipping class to fuck, but it helped reduce the problem.
Men with GID couldn’t decide for a while if they were now just attracted to all men without differentiation, or if all men had now just become attractive due to the muscles and cocks GID gave them. It wasn’t either, exactly, but GID had rewired their sense of attraction so that most men could be attractive to and consequently enjoy sex with most other men. Between that and the super high sex drives, men found themselves having sex with all of their male friends and, for that matter, nearly any guy they happened to meet when they had time for sex or were too horned up to avoid it.
Sales of poppers quietly rose as word spread that they did amazing things for the Converted.
Doctors finally started to notice that people with AIDS who had contracted GID suddenly showed no symptoms and began to recover, even if they weren’t on any drugs. The National Institute of Health reported that there had been no reported new cases of any sexually transmitted disease in anyone with GID, and random sample testing showed 100% negative results. They were astonished as they’d been expecting a high disease rate based on the sudden huge rise in promiscuity. The researchers were so delighted with the news they all went off to a conference room to celebrate by enjoying each other’s cocks for a few hours. It would take a little longer to notice the disappearance of the common cold.
Nursing home populations fell as elderly men who were too old and weak to walk around found new bodily strength and new sources of fun in each other’s no-longer flabby bodies.
In the Brooklyn loft, the Engineer looked at his calendar as he got a drink from the fridge and saw that Phase 4 was scheduled to begin the next day. Phase 3 had been a raging success. Opposition to the spread of GID had melted away as people took delight in their bodies and fantastic sex like they’d never imagined, and his program to bring poppers-soaked sexual frenzy to men everywhere was slowly succeding by word of mouth. However, Phase 4 would be a bit more extreme and he wondered how the world would react. Ah well, they had no say in the matter, his tiny creations were going to carry out the program to his tastes and no one could stop them.
The two men he’d picked up at the coffee shop were already getting stupid on poppers on the sofa in the living room. The Engineer decided he would hold off on that himself for a little while so he could keep his wits about him and use the guys to get what he wanted… and what he wanted tonight was oral. Lots of oral. He was going to suck cock and fuck face until one of the guys, starting to come down from their current hit, shoved a bottle in his nose and took away his ability to decide for the rest of the night. Phase 4 was coming, and everything would change… again.
The next evening the timers built into all the GID nanobots hit phase 4, and the next round of changes began.
Men everywhere started having tingling feelings in their cocks and asses again, but few noticed becuase most either were already having sex or just took it to mean they felt like having sex… which they felt like most of the time these days, so it wasn’t worth much concern. But, after about 12 hours, some men started noticing that their cocks had grown again. Indeed, all cocks were growing again, but more slowly this time, and in some cases slowly enough that the men might not notice for a whole day. However, with all the focus on sex since GID, everyone eventually did notice.
Before Phase 4, cocks had grown into the 9 to 12 inch range. By the end of the first day of Phase 4, most had grown into the 12 to 14 inch range with substantial added thickness, and growth was starting to accelerate. Along with this growth came a kind of tingly, empty feeling in the ass, and the first 8 to 10 hours of the second day of Phase 4 were accompanied by frantic fucking among a world population of men who all suddenly wanted a cock in their ass.
By the middle of the second day of Phase 4, it was pretty obvious to everyone that cocks were going to be enormous. Huge. Monsterous. Indeed they already were, and pants were starting to become significantly problematic. Men were starting to have to walk around with their massive cocks out in public as they tried to figure out what to do about clothes… but of course, the sight of so many hot men walking around with their cock out started to lead to impromptu sex in the streets. Nobody intervened… there weren’t enough female cops to really do anything about it, and the men were too busy being distracted by new growth.
Cocks were getting absurd, and even the sex-crazed men of Earth knew it. Many felt shocked, many were upset, but everyone knew that nobody knew how to stop it. Most men got together in small groups to get naked together, sit down, stare at their cocks and stroke together. They didn’t know what else to do.
By the end of the second day of Phase 4, About 40% of men had reached their full new cock size, and the rest would within a day unless they took longer because they weren’t eating enough to power and supply their nanobots. The results were definitely shocking. The average cock now fell into the range of 18 to 22 inches long, about 6 inches thick, and about 14 inches around. When hard, most guys could now just barely put their fingers all the way around their cock if they put the tips of both forefingers together on one side, and the tips of both thumbs on the other. Stroking off was now a two-handed job. Many guys could lick the tip of their erect cock by simply sticking out their tongue because it reached to or just below their chin when hard… and everyone could get hard. Everyone knew sex was going to have to be different now, and a lot of men were initially afraid to try fucking. It was very upsetting: how the hell was a cock that massive going to fit into anything? But, as with anything sexual, a few adventurous souls had to know and gave it a shot.
The graphic designer had been a rather portly man, and consequently underwent all the transformations quite quickly because his weight gave his nanobots plenty to work with. First he had filled out a nice big his cock nicely, then his weight transformed into muscle leaving him looking much like a competitive bodybuilder muscle-god type would have before GID, and then when Phase 4 hit he found himself the proud carrier of a 20.5 inch cock… about six and a half inches larger than he had ever imagined a cock could possibly be, and far thicker. It was… upsetting.
It was morning, and he was at the gym, which had become the defacto mens meeting place and sex club for his part of town. He was in the crowd in the workout room where most of the guys had settled down to be together through the latest round of alterations to their bodies. The previous changes had been fun, but this one was scary. The earlier jubilation that cocks were getting larger quickly gave way when it became clear that they were going to be too large for most conventional sex to take place. Men were sitting around nude, staring in shock at their absurdly massive dicks, or holding the massive meat in their arms and crying. Some were blubbering about how much they would miss fucking, or getting fucked, or sucking cock, or getting deep throated. Everyone was upset enough that actual sex, even stroking off, had ceased for a few hours and the only contact going on had been men hugging and comforting each other.
The graphic designer was as stunned as the rest, but a bit better at restraining his expression than most of the rest, so he appeared to the others to be sitting contemplatively instead of freaking out. A college freshman seated very near him noticed his apparent composure and made a decision. Crawling over to the graphic designer, he started licking the head of the designer’s monsterous cock. The designer was obviously a bit surprised, so the student decided to explain. “I want you to try to fuck me,” he said, “so I need to get you hard first.”
In a bit of a daze, all the designer could say was “oh.” He could’t figure out how the heck it would happen but he could at least try to enjoy the oral attention and see if he could shake himself of the shock.
Enjoying it became a bit easier as a few other surrounding men decided to join in the licking. With six mouths avidly drooling on and licking at his cock, the sheer sensations rapidly hardened it into a giant ramrod. Soon the college student moved to position the head of the designer’s Cock at his ass, and the designer prepared himself for some uncomfortable pressure and the disappointment of the student. But, to everyone’s surprise and delight, the cock head slipped right into the student’s ass and just kept going. Had their asses been loosened to accommodate? Apparently… soon the designer’s Cock was buried deep, deep inside the student and they stared in surprise into each other’s eyes as they sat more or less face to face with their arms and legs wrapped around each other.
And then, it happened. Softly at first, but rapidly growing in strength, the designer felt the inside of the student’s body send waves of hot, moist massage rolling up and down the length of his massive shaft. It was as if a tight, hot, wet, giant mouth was giving him the world’s largest blowjob as the new chamber of the student’s converted ass flexed hundreds of tiny muscles in sequence while releasing a thin layer of lubricating liquid to pleasure him. It was, bar none, the most intense pleasure he had ever felt, and he was gasping and panting with delight.
To the student, it was slightly different. He felt every inch of the absurdly expansive member lodged inside him and was filled up by it. The throbbing of the massaging action of his ass felt to him as if he was being fucked by the giant cock even as he sat still, sending waves of pleasure through the very core of his being. He felt utterly fulfilled, as if for the first time in his life he was truly complete—completed by the man with the massive cock who had for the moment become one with him. He felt so overjoyed by it that tears of joy streamed down his face as he passionately kissed the designer, pressing his own throbbing pole between them as they embraced.
The onlookers stared in amazement at the couple as they writhed and moaned in joy. Soon someone hesitantly produced a bottle of poppers and placed it under the student’s nose. As the student inhaled, he felt the bottom drop out of his mind as the pounding and pressure of poppers rapidly filled his head. As the onlooker gave the designer a short, he too lost control and his mind. The two of them had had little enough idea what was happening to them before they got high, and now they had no ideas of anything at all, and the intensity of the pleasure increased to the level that they both felt constantly on the edge of the biggest orgasm of their life.
The next eight hours were a blur of sexual ecstacy filled with the intense feelings of the designer’s cock and the student’s ass, the designer’s massive musclebound torso, the student’s boyish face, the pounding of poppers in their heads from hit after hit from the brown bottle, the student’s cock pressed between them, and the occasional slight dribble of precum from its head, which now tasted to the two better than anything they had ever eaten or drank. At the end, they both shot loads of cum larger than anything ever seen before. Deep inside the student it immediately began to be absorbed by his ass, while the designer was overcome by desire for the scent of the student’s load and joined him in lapping it up. The cum filled each of them with a feeling of utter satisfaction and contentment as they came down from the drugged stupor of the poppers.
Some of the others were immediately choosing a partner to try the New Fucking with. Others were frightened and needed to adjust to the idea before trying it. But, they and others like them who had witnessed similar adventurous scenes—seen the world over in other gyms, private homes, school locker rooms, parks, even Times Square—spread the word that the new Cocks were not useless, and sex was changed forever.
Medical researchers had determined that GID was caused by an artificial self-replicating nanobot, but gave up trying to figure out how it worked and whether or not they should try to stop it when the bodily changes of Phase 4 forced them to drop everything to study the new bodily structures. The Cock was a very obvious change, but the internal changes were more severe as organs had been slightly rearranged to make room for the massive cock massage sheath inside the ass. The colon was no longer, as the nanobots were now using any excess material from the digestive tract to replicate and as energy to repair large physical problems with the body… such as correcting pulled muscles, broken or weakened bones, blindness, even paralysis. Any leftover material was used to replicate nanobots which would then leave the body. The ass was now strictly a pleasure organ as it was no longer needed for other purposes.
It was a good thing the birth rate had dropped, because with all the medical benefits of GID there were a lot more healthy (and horny) people suddenly walking around who otherwise were dying or would have already died. However, the birth rate was dropping off to essentially zero as women who were already pregnant gave birth, men were no longer having sex with them, and women, all lesbians now, wanted nothing to do with those ridiculously large cocks anyway. Governments and the United Nations formed study groups to examine the problem and recommend both cultural and technical solutions for perpetuating the species.
Women, as a group, were upset that they’d had to keep the businesses of the world going more or less without male help for two or three days as men underwent Phase 4, had New Sex like maniacs, and got over the initial shock and novelty, but the Engineer had compensated them with eternally youthful breasts as his gift for Phase 4, so the complaints were not too vehiment.
The only men left on Earth who had not yet been Converted by GID were a remote tribe of native Brazilians who lived deep in the rainforest and only had contact with conventional civilization about every six months. They were in for quite a surprise when they eventually came across a team of nature photographers, contracted GID, and underwent all four phases of transformation within a day. Their cocks grew so fast the growth was visible… and this, of course, became what happened to boys as they reached puberty.
Fashion designers and clothing manufacturers found themselves in a brief boom as new menswear had to be designed to accommodate the giant new cocks. Nobody’s pants even remotely fit after Phase 4 hit, and the Cocks didn’t really fit in regular pants anyway. It couldn’t be left to just dangle, as it tended to trip up the feet if not outright dragging on the floor when it wasn’t hard. Various solutions were tried ranging from jumpsuits with internal straps to hold the cock up along the chest, to pants with a third leg. Ultimately the popular solution became that when it was warm enough and an appropriately casual situation, men would simply wear it hanging out through a hole in the front of their pants, draped over a sort of sling arrangement in the front of their shirt. In cold weather, insultated jumpsuits were the outfit of choice.
And back in the Engineer’s loft, the engineer wasn’t in. He was in Central Park, in the middle of a circle of one thousand men, each with his cock in the ass of the man in front of him and his ass clamped on the cock of the man behind him, as a public expression of the new male sexuality. He’d get to thinking about his creation another day. Today he, like the other 999 men and most men everywhere, were too filled with cock, poppers, and pleasure to care.
The total GID conversion of humanity had, of course, huge societal implications.
The nearly 100% divorce rate had of course immediately overwhelmed all the divorce courts. Only a few religious radicals tried to remain married to opposite gender spouses after Phase 4, and even most of them gave up fairly quickly. The public at large tended to look on them with derision and pity, as if viewing someone who is obviously slightly insane but not harmfully so. Breakups were less acrimonious than would otherwise have been expected, since couples didn’t have any particular reason to hate each other, they just suddenly found themselves no longer attracted to each other. Many formerly married couples managed to remain friends.
Most governments fairly quickly decided that the only reasonable reaction was to declare that all heterosexual marriages were now legally ended, and start setting up special laws and agencies to provide legal assistance to formerly married couples in separating their posessions, finances, and homes. Relocation bureaus helped match prospective roommates for temporary residence until people could select permenent residences. Women tended to spend a few weeks or months getting to know a lot of people, then make some choices and settle down. Men tended to just settle in wherever they were placed and stay for at least a few years: if they weren’t having regular sex with their roommates, when they weren’t at work they were probably too busy having sex with someone (or many someones) else to actually see enough of their roommates to care who the roommates were.
It soon became clear that new types of housing were required. Women seemed to want fairly traditional houses with an increased number of full size bedrooms, and tended to set up house in little communal arrangements of several devoted couples. However, this tended to require modification of existing houses to add bedrooms or enlarge existing ones. Men seemed to be drifting toward wanting simple, spartan quarters with a number of small individual mens’ bedrooms for storing clothes and personal items and a small bed for the rare times they wanted or needed to sleep and do so alone, and a few shared rooms for cooking, eating, TV (usually only used for news these days since there were more fun things to do with free time), and a nice big, padded, easily cleaned room for group (or paired off) sex.
These architectural changes required a lot of construction work. Meanwhile, some other industries, like movies and TV, were suffering rather badly from lack of mens’ interest, and some, like porn and condom manufacturers, were basically closing entirely. This created a flow of available workers onto the market. Recognizing the need for, essentially, reworking all existing housing to meet new demand, construction unions took on and trained many new members, and government housing bureaus tended to supply plenty of construction contracts to help individuals set up appropriate housing for their new lifestyles. Of course, this meant that taxes rose temporarily, but since almost everyone was moving toward group housing, cost of living actually dropped.
It had been one year since the group house had been built and Steve and all his buddies and all their buddies had moved in. At 137 men, it was the largest mens’ home in their rural town. Steve was often one of the first home, as the insurance brokerage he worked for was only a few miles down the road. Ditching his suit in his room—little more than a closet with a twin bed, really—he strolled toward the kitchen, wearing only a light wrap designed to hold his Cock up off the floor and keep him clean during cooking. Being one of the first home, he often helped out with the cooking. After all, the sooner dinner was cooked and eaten, the sooner everyone got to the playroom.
Dinner for 137 plus invited guests was actually pretty easy, since it was a nightly event: the house had simply bought a complete set of industrial kitchen equipment. So, between equipment and manpower, it was just as quick and easy for them to make a dozen pans of lasagna, pots of spaghetti, trays of steaks, or anything else as it would be for any old-style household to make dinner for 6… perhaps easier. The House Elder was a formerly retired three star chef—a lucky catch for them—and the house members had decided that even though he was perfectly able to return to work thanks to GID, he should be able to his days off and enjoy his golden years. He, in turn, loved to plan meals—much easier than running a restaurant because he didn’t have to make a different dish for every man—and exercise his creativity in the kitchen. His usual procedure was to get the meal started and then hand off the work to volunteers as they came home and drifted into the kitchen. So, as Steve walked in, he got put to work saucing pork ribs, which someone else then put on the grill. In about 15 minutes his part of the work was done and he was sent off with thanks. He popped back to his room to ditch the wrap he was wearing and, Cock in hand, went to the TV room to catch the evening news.
He ended up on one of the sofas with a few buddies, with their legs all tangled together, slowly jacking each other’s cocks… jacking together was fun, and probably as intense as it should get before dinner: fucking before dinner was socially acceptable now, of course, but most guys got to feel frustrated if they had to stop fucking to go eat, so best not to start that until they’d eaten. The news was kinda boring… this and that war had officially come to an end by treeaty after fighting had actually ended five years ago, a religious womens’ group was trying to ban the weekend sex festivals in the park but the police and city council had told them that trying to ban men from having sex was like trying to ban men from breathing but that perhaps some womens’ parks could be created, a company had just released a new wheeled product designed to help dwarves and other little people carry around their giant Cock, now often almost as long as they were tall, and there was a bill in the state legislature to double funding for schools. That’s good, Steve approved of good schools. Damn these guys next to him had nice legs, and they were good at jacking him too. But, the dinner bell sounded, and everyone got up to pull something back on to keep clean during dinner.
Dinner was delicious as always. Some guys who had arrived too late to help out with the cooking were collecting the dishes to put them in the dishwashers—the pots and pans were already being cleaned while everyone ate—and everyone else went to the playroom, dumping their wraps in a barrel by the door. All clothes in the house were labeled, some guys would dump them in the big industrial laundry machines the house owned before leaving for work in the morning, and they’d be distributed to their owners’ rooms by other volunteers in the late afternoon during the cooking.
The biggest room of the house, it had an inflatable padded floor with a waterproof surface, sloping gently to one side where there were drains all along the wall, sprinklers on the ceiling, and a plastic curtain that could cover the door. Each morning after everyone left the playroom for the big gang showers to enjoy humping away for half an hour while covered with soap, the playroom would be set to its self-cleaning cycle, which would wash away all the cum splattered everywhere from the previous night’s sex. Even though cum was now desirable and delicious to all men, inevitably with so much of it being shot so often spots of it would slowly get all over the floor, so it was important the playroom be cleaned daily, and of course it was easiest to build it to be self-cleaning.
The house also had quite a few fuck chairs for the playroom, designed to support two men as one rode the other’s Cock, but they were in the big playroom closet tonight: it was wednesday, which was lights-out night in this house, so there would be no furniture to trip over in the playroom. The floor would start out deflated so the men could fuck standing up, and after three hours would be inflated so they could fuck laying down.
A few guys had already paired off with a special favorite lover or two or three and formed small groups in the far corner, already starting to fuck, but most guys were just milling about, slowly jacking. A minute or two later, the last of the men in the house arrived in the room and touched some controls by the door, which lowered the lights throughout the house to a dim glow, lowered the house heat in the common areas to save energy, closed the door on the playroom, and turned up the playroom heat slightly. While the heat of 137 bodies would mostly keep the fairly heavily insulated and windowless playroom warm, it was best to ensure nobody would have to deal with heat during the night. The alarm for the next morning was set, and the lights of the playroom went out, plunging the men into pitch darkness.
The house rule for lights-out night was, if you want to have sex with anyone in particular, you pair off with them before the lights go out and go play in the opposite corner, or go take them to your room for the night. Everyone else was to mill about in the crowd for a few minutes so you wouldn’t have any idea who was around you, and then when he felt ready the House Elder would give the signal to start fucking. Steve found this procedure to be incredibly sexy as the crowd moved around, touching each other, and he felt a hairy pec… a muscled arm… a big hand sliding across his ass… a shoulder brushes against his chest, and its owner pauses to lick his nipple before moving on… a Cock slides all the way across his chest, its owner shoving a tongue into his mouth on the way by… someone’s furry ass bumps into his… and the voice of the House Elder calls out “Commence fucking!”
Reaching out to feel around him, Steve found an ass just to his right, so he backed up slightly to give him room to guide the head of his Cock into it. Slowly he buried himself in the ass to the hilt, and as the throbbing and tightness of the hot ass began to try to milk him of his cream he reached down to feel who he was fucking… hmm, smooth, slim, nice muscled arms… could be a number of the men in the house. Could also, in fact, be his own 17 year old son Jason, which added to the thrill. They’d never actually found themselves lost in fucking with each other when the lights came up in the morning after a lights-out night, but he supposed that as long as they stayed in the same group house it would eventually happen someday, and for that matter they’d almost certainly jacked off, humped, licked, felt each other up, maybe even fucked in the anonymous dark at some time already… but without proof, they didn’t need to consider it: many guys liked lights-out night entirely *because* it was a crowd of anonymous, nameless bodies to use and be used by, so it was socially accepted that anyone who didn’t identify himself in the dark wasn’t to be assumed to be anyone in particular. Whoever it was Steve was fucking, his ass was tight and hot and throbbed and squeezed and sent waves of happiness through Steve. Steve was particularly loving this one, he was really an amazing fuck.
Behind him, a hand brushed by, felt his ass, and whoever it was turned and began sliding his Cock into Steve’s ass. Steve *loved* the feeling of it sliding in, filling him up, making him complete. Mmm, this one had a slight twist to the left… GID didn’t introduce any turning or curving into the Cock when it made it enormous, but if there was any there already it perpetuated it, so this top’s Cock twisted slightly along its length. Hmm. Not too many guys in the house had a Cock like that… and this man was actually fucking him, not just burying the Cock in him and letting the Cock and ass do their magic, as most guys did…
“Yeah man, take it…” the top whispered in Steve’s ear… “I love to fuck you, you’re so tight” and a chuckle. Yes, it must be Scott. Blond, smooth, with a beautifully muscled chest and a happy, boyish face, Scott was one of the men who Steve was most attracted to in the group house. Of course, Scott was one of the men who everyone else was most attracted to in the group house as well, so he generally had his choice of sex partners for the night. Come to think of it though, Steve had had Scott’s Cock buried in him fairly often lately… and it felt soooo gooooooood… “I knew it was you from the fur on your ass,” Scott said, “it feels different from all the other guys.”
Steve’s head reeled from the ecstasy of having his Cock buried in the ass of the unknown guy in front of him, and Scott’s Cock fucking deep inside him. The pleasure was too intense, he was soon lost to rational thought for a while, not from drugs yet—the house rule was, no poppers for the first hour and a half of sex—but just from being overwhelmed by the sensations of pleasure rushing through his body. His cock being squeezed and massaged and milked by the ass in front of him, so tight and hot, perhaps the best ass he’d fucked yet… his nipples and chest brushing against the soft smooth skin of the unknown man’s back… his arms wrapped around the man’s slim form and his hands moving over the unknown man’s muscled chest, feeling his six-pack and fondling his nipples and wondering if it was Jason and yet glad he didn’t know… and from behind, Scott’s beautiful, muscled arms wrapped around him and fondling his chest… Scott’s Cock pounding the inside of his ass… and Scott’s breath, hot on the back of his neck.
He came several times, felt Scott cum inside of him several times, felt the tight squeeze on his Cock as the guy he was fucking came several times, and lost track of time until there was a soft tone, and a minute later bottles of poppers were being handed around, so it must be an hour and a half now. Someone nudged his arm and handed him one, and he felt Scott take one hand off of his chest to take one too. Quickly, before Scott could get any ideas, Steve decided he had to know about the guy he was fucking, so he opened the bottle he had taken and put it in the nose of the guy on his Cock. “Yeeessssssss,” he heard the guy hiss, as the guy snorted a hit… two… threee… and then the guy moaned slightly. The guy would be good and stupid by now. Jason had a small mole behind his left ear, and if it was him Steve didn’t want him to remember feeling as Steve touched to see if it was there… and it was. Oh my god, he was fucking his own son. He felt it was wrong, but yet they had both understood it was possible when Jason chose to join the mens’ house with him, and at the same time it was exciting precisely because it was taboo, slightly so even now after GID had transformed the men of Earth.
He wondered if he should pull his Cock out of his son’s hot tight ass, and push the boy away so he wouldn’t find his father fucking him in the morning, but Scott chose that moment to shove a bottle of poppers in his nose, and just as he was inhaling no less, so he didn’t get to stop to think before snorting in a hit. “I want to talk to you in the morning,” Scott whispered in his ear as Steve exhaled his first hit, “because I’ve had my eye on you for a year now, and I’ve got a crush on you. I think you like me too, and I’d like us to be primary lovers. Don’t worry about it now. Let the poppers take you. We’ll talk in the morning…” and at that, Steve’s mind gave way as the pounding and pressure of the poppers took him over for the night. Scott took a few moments to savor the feeling of fucking this man he felt he might be in love with, wondering in amazement that only a few years ago he had a young wife but now she seemed a million miles away and this hairy man was the center of his world. Remarkable. He put the bottle to his nose and inhaled deeply, enjoying the feelings of losing control. As he felt himself slipping away completely to the thrall of the sex and the drug, he put the cap back on the bottle, put his arms around Steve, and rested his head against Steve’s back.
In the morning, the lights would come up, the men would come down from their high, and they’d go to the gang showers to soap up and hump before preparing breakfast. And Steve would have a lot to think about.
Human reproduction was now a more complicated issue, as men and women no longer desired each other and, anyway, their anatomy would no longer fit each other. While a few more totalitarian governments toyed unsuccessfully with trying to force sperm donations and paternity, most had to accept that men only wanted fatherhood on their terms. More agencies were set up to help match up people of opposite genders who wanted children, but this didn’t work out too well either at first. In the end, it was determined that people not only had to be able to determine if they wanted children, but the terms on which they wanted them. Some people wanted to reproduce but then only have occasional visits with their child. Other people wanted to be a full time parent. Some were willing to reside near or in the same building with the other parent of their child. Others wanted to live separately and have a time-sharing arrangement over the child. A few even were willing to donate sperm or give birth, but only with no strings attached. Laws had to be changed to allow parenting contracts specifying exactly what rights and responsibilities regarding the future child the opposite gender people would have, allowing people more flexibility in their reproductive choices. Agreements including the stipulation “if it’s a boy the father will take custody, if it’s a girl the mother will take custody” were common, although not universal. To encourage further procreation, laws were also created allowing men and women to choose to have a baby but accept no responsibility, with the child being raised communally in a public care center, and the parents only having visits when they wanted to. Parents having children in this manner could later choose to accept responsibility for the care of their child, and many did, but it was a useful way of encouraging people to make a genetic contribution to the species who otherwise didn’t want the trouble of caring for an infant.
Upon reaching puberty, boys would undergo the full GID changes within a day, which was of couse quite an intense experience for a boy to have as he went from a small endowment between his legs and no particular sexual interests to having an enormous piece of man meat and an uncontrollable desire for men within hours. It became the new male rite of passage, and when the changes set in a boy’s male family members and a few of their friends would usually turn the day into a party for him. Teen sons of family friends, and/or the boy’s friends who had already undergone puberty, would volunteer to take turns satisfying his suddenly uncontrollable sexual desires, which were particularly insatiable for the first week or so. Also at this time, if the boy had been living with his mother, that arrangement would now be, in practice and legally, over, since he would find it overly sexually frustrating to live with his new libido in a mostly female environment, and they probably wouldn’t enjoy having an overly randy teen boy around much either. He would therafter see his mother for short but cordial frequent visits. If his father had agreed to provide housing to the boy in his teen years as part of the paternity contract, or had since become willing to provide housing to the boy anyway, and the boy wanted to, he could join the father’s living group. If not, he would join a teen boys’ group home.
Tom was 11 and slightly pudgy. Everyone knew puberty could hit that early, they’d learned it two years ago in their health class lessons on the changes their bodies would be undergoing soon, but he didn’t expect he’d be the slightly early one. But, as he ran through the playground with his buddies during recess, he started feeling tinglings in his privates and a tightness to his underwear. He’d been cautioned very strongly that he should report this immediately, so he did and the teacher sent him to the school nurse. The nurse asked him to drop his drawers, and with one glance he smiled and told Tom to sit down and enjoy, today was his puberty day and he’d be having a party. Tom was a little bit frightened—you know the stories the other boys tell, of course, about cocks that never stop growing, or asses that get big enough to take a car—but the nurse seemed so relaxed and happy as he called Tom’s parents, Tom felt slightly reassured. His parents dropped everything and quickly arrived at school, his dad first to give him a hug and congratulate him, followed by his mom. She was a little sad that he wouldn’t be staying with her any more, but put on a happy face and gave him a big kiss on the cheek as she congratulated him as well, reminding him that while he’d be staying with his dad now, she’d see him several times a week as soon as Puberty had passed, and he could call her any time. His dad told him to just take the pants all the way off, they’d get him new ones later… Tom looked down and saw that his dick wouldn’t fit into his undies any more anyway, and come to think of it the extra weight on his belly was disappearing rapidly. With that they took him outside and put him in his dad’s car. He watched as his parents talked for a moment and hugged—they’d stayed close friends after GID broke up their marriage—and then his dad drove him to his new home at the mens’ home. He’d been there before, but only for pizza and videos on saturday afternoons when the weather was bad.
“I called your older friends’ parents on the way to the school,” his dad explained, “so they’ll be arriving shortly after us. Don’t you worry about a thing. Uncle Richard is getting food now, too.” It hadn’t occurred to Tom to worry about food or who was showing up, he was more concerned about what he would look like, what he would feel… what he would BE when GID was done altering him into, well, whatever it was that post-pubescent boys were these days. A couple of his slightly older friends and their older brothers, not more than a couple years older than him, had undergone the change already and they had become strange, incomprehensible beings, always staring at each other and the other boys around their age with funny little grins, always rushing home to their mens’ homes or teen boys’ homes after school instead of staying to play sports… and those cocks, those huge cocks, he couldn’t understand how they could live with those, they seemed like such an inconvenience. Now he’d have to find out. His own had already grown substantially and was giving him squirmy feelings he felt a growing desire to somehow relieve.
As they entered the mens’ home, a man he didn’t know approached to tell them they could use playroom 3 for as long as they wanted. Tom didn’t know the man, but couldn’t help noticing his nice muscular chest, covered with thick brown fur that Tom longed to bury his face in and lick the man’s nipples… whoa, where had that come from? He’d never thought about anything like that before… and the man noticed Tom noticing him, and smiled as Tom and his dad left for the playroom.
In the playroom, his dad guided Tom to a special soft chair designed for sex, one of many new pieces of furniture designed for the purpose in the last few years. This one would allow him to relax and recline slightly while spreading his legs to expose his dick and ass. His dad helped him find a comfortable position in the chair, relieved him of his remaining clothes, and got a bottle of lube from a shelf, squirting a small blob onto Tom’s growing dick and suggesting Tom could stroke it until his friends arrived. Tom was reluctant, but with his father’s calm encouragement he began to stroke, and felt *so* much better as he realized he’d needed to do this for hours. He felt a little embarassed doing this in front of anyone, but his father kept looking into his eyes and telling him to relax and enjoy it, everything would be fine.
“Uncle” Richard, formerly his dad’s best buddy from college and now his dad’s primary lover, came in with an armload of stuff, and congratulated him on his Puberty as he set up a small folding table next to Tom’s chair and began to set out food. At the sight of potato chips, ice cream, fruit, and meat, Tom suddenly felt ravenous and started to reach for food. “No,” his father told him, “that’s our job. You just sit back and enjoy yourself, tell us what you want and we’ll feed you.” And with that, they sat down around him and stuffed him with anything he wanted as he sat back and stroked his growing cock. He’d need lots of food to fuel not only himself, but also the nanobots which would be changing his body, constructing muscle and Cock for him at a furious pace in the coming hours.
Just as he was finally starting to feel—at least for the moment—full, a shout of “TOM!” went up as his friends Chris and Mike tumbled happily into the room. They were friends from school, and despite that they were a year older than him, the three of them had always been inseparable until, within the last few months, Chris and Mike had each had their Puberty. As it happened, each had stopped hanging out after school and on weekends, and Tom was feeling very left out, confused by their behavior, and a bit scared of this Puberty thing that would make people change so much.
As the boys stripped, Dad and Richard excused themselves to leave the three alone for a while, making sure Tom knew they’d be checking in regularly to make sure he was staying fed.
Chris and Mike seated themselves straddling Tom’s legs, with their massive cocks resting on his shoulders, and began stroking his growing cock for him. It wasn’t that Tom was exactly surprised by this—after all, he knew from his lessons in school that they were here to help him through Puberty by having sex with him to satisfy his soon-to-be insatiable desires—but having never before been actually touched sexually, it was an unaccustomed feeling to have two giant throbbing cocks resting on his shoulders, two hands stroking his cock and balls for him, and his two best friends sitting naked in his lap smiling down at him. Funny how he’d never noticed how perfectly beautiful their faces and chests were before… he found himself reaching up to touch their nippes as they leaned in to put their arms around him and each other so they could hump their cocks together. As their tongues came together in their first joint kiss as a trio, he realized that Puberty was going to be all right: it wasn’t just that they’d soon be united by their cocks impaling him and his them, but rather that they’d always been united by their friendship, and now that they would come together in unimaginable pleasure every night, they always would be. Chris and Mike would have to go back to school in the morning, and other boys would take shifts being excused from school to keep Tom occupied during the days for the next week while his out-of-control sexual desires held control of him, but he knew that every night Chris and Mike would be with him, and he’d be spending his nights in their arms for as long as they lived.
Outside the room, all three boys’ dads stepped away from the door they’d been peering in, and there was much shaking of hands and patting of backs. Clearly the boys’ bond was going to last. They had an hour before Tom’s dad and “uncle” needed to be back to make sure Tom was keeping himself fed for the transformation… just enough time to start a little bit of male bonding between the fathers… in playroom 2.
It soon became clear that the birth rate would never be the same as what it was before, although it eventually stabilized at a high enough level to ensure the continuity of humanity. No one was ever sure if this had been designed into the nanobots to ensure the perpetuation of the species, or a lucky accident. The Engineer had not revealed himself and attempts to determine the origin of GID hadn’t been able to narrow it down further than “the New York area”, so he wasn’t telling.
This would create, for eight to ten decades, a relatively high ratio of older to younger people. Fortunately, thanks to the health-maintenance aspects of GID, older people now tended to be able to be active and productive until they experienced a fairly sudden, relatively painless death with no lingering suffering, so they didn’t require much of the massive family or public expendatures on health care to maintain the elderly that were previously required.
As their bodies were now visually rejuvinated by GID, the elderly no longer appeared as unattractive, wrinkled old prunes, but rather as dignified, handsome, fit, attractive members of society who just happened to be older and have more experience. The elderly were, therefore, generally welcomed into living groups as a kind of “senior member” and found themselves enjoying sexual adventures they had thought were long past them.
Grandpa was getting ready to cum. Waves of intense pleasure crashed through him as his cock was squeezed and massaged by the incredible tight ass of the boy riding it. The boy was 18, the youngest member of the household, having just joined the living group two weeks ago upon departing a teen boys’ group residence shortly after his high school graduation. Grandpa was 78, but had the body of a well worked-out 25 year old, except with soft grey body hair instead of brown, weathered-looking skin, and a distinguished, rather than youthful face. Overall it made him an imposing, and much admired, figure to look at, and the boy was very eager about servicing his elders in the playroom, so grandpa didn’t mind that the boy was actually younger than his own grandsons.
The moment finally came, and he moaned loudly in almost a scream of continuous pleasure as he rode the wave of orgasm, which took longer than he’d ever known before as he felt his massive load of cum pumped all the way up the length of his huge tool and erupt into the boy’s ass. As the last of it was deposited and he felt his cock soften in the boy for the 30 or 40 seconds of downtime it would get between fucks, he heaved in his breath, breaking away for a moment from the lips of the frantically kissing boy in his lap. God, the boy was beautiful. Everything a man could want in a boy to play with, he was slim and boyish of figure yet just muscled enough to have a little definition, with soft skin that looked smooth and creamy, and firey red hair gently spiked on his head. So beautiful… so fuckable… and grandpa felt himself hardening again inside the boy, and at the feeling of it the boy shot his load in their faces. Fresh cum… it smelled soooooo gooooood, and they both licked it up eagerly. He remembered once thinking his own cum smelled bad when he stroked off, back when he had a wife and had stopped having sex because as they’d grown old she lost interest, and couldn’t imagine how he could ever have thought that. Mmm, the boy was already getting hard again from the two of them licking at his cockhead. Nice.
Other members of the living group were drifting into the playroom, smiling as they saw him gently fucking the boy as the boy’s ass worked its magic. Several paused to kiss him and/or the boy deeply on their way into the room. Some were already pairing up to fuck, others were just hugging and humping together with several men, waiting for the rest to arrive. Frank was away on a business trip for the week, no doubt spending his nights with his ass filled with the cocks of all the men in the transient mens’ sex club if he hadn’t been taken home by one of his clients first. Jack had brought home a coworker to play for the night, who was already starting to fuck him. Grandpa felt a goateed face kissing his lower back, knew that Alex had arrived, and with a smile he moved to a kneeling position—with a moment’s happy thought that his arthtiris was gone, allowing him to do it—so he could be entered as he continued fucking the boy.
Alex moved away for a moment to set the alarm on the wall to have them all conscious by 7am, and pushed the buttons. The curtain closed over the doorway, and a device in the ceiling hissed poppers into the air of the room. How had he managed to live 73 years without discovering poppers before GID came along? He loved the feeling of the gas taking him, as he breathed in hit after hit and it forced all thought out of his mind, leaving him a happy animal, fucking a beautiful boy as an enormous cock slid into his own ass, filling him with endless sensations of pleasure and fulfillment. It was good to be the House Elder. Life had never been so good.
Large standing armies started to seem fairly useless. Men tended not to be very interested in fighting each other any more: strong disagreements tended to end in wild sex followed shortly by a compromise agreement and more wild sex. Also, the frequent battles over religion that had plagued the earth for thousands of years largely vanished as men tended to lose interest in religion in favor of obsessive interest in sex. The few male religions that cropped up were almost entirely flimsy excuses to worship cock, and then of course actually have “ritual” sex, and were largely a method of self-justification for men with emotional problems adjusting to their new desires, by allowing them to tell themselves they hadn’t become gay so much as they had changed religion.
The Engineer’s employer had, ironically, reassigned him to study the new bodily structures created by GID. As he had designed them in the first place, he could write out remarkably accurate “research” results… with just an appropriate margin of error added for realism… freeing up much more of his time on his own research work. He was working on plans for another series of nanobots. This batch wouldn’t make obvious external changes. The engineer wanted to cure allergies, asthma, and cancer. While he was at it, he was unhappy about the decline in culinary standards among men: since men now mostly wanted to come home, wolf some food down, and then spend the rest of the night having sex, most men were moving toward bland, microwavable food, but the Engineer liked real food with real flavor. So, as an incentive to eat French food, men altered by the new line of nanobots would get very stoned on vichyssoise, and would find that meals containing a combination of butter, wine, and shallots would now be mildly hallucinogenic in a pleasant and erotic way. The Engineer felt pleased with this concept… It should get men interested in tastier food, followed by them getting even more stupid for the night and having lots of sex. Just what he always wanted.
