The CUM-mission

by UberPump   

Our character experiences a serious case of blue balls as he’s awaiting for a story commission from UberPump. He’s been edging for hours with no relief as his balls swell with gallons upon gallons of cum....

This anonymously-commissioned story contains balls exploding from too much cum. Reader discretion is advised.

“Ooooo! I can’t wait for this story from UberPump!” I groan, grabbing my hardening cock through my shorts. It’s thick 8-inch length filing the palm of my hand as I feel the veins and ridges flaring and pulsating, my cock head stretching out of the foreskin as its pulled taught over my 2-inch-thick cock. I take a whiff of the smelly man musk emanating from my fat cantaloupe sized nuts. I’ve been edging for hours, and they’ve just been getting bigger.

Sitting down on the chair in front of my computer, jacking my cock off, I await for the story to be sent. My balls ache for release as they stretch my sack out. I can feel them pulling on the cords as all the testicle meat bulges and pulls on them. Cum is desperately trying to escape up my shaft, but the cock ring I have on blocks any attempt for escape.

“Unnnnguh…. You’re so fat. Gotta keep edging… I wanna save this load for the real fun!” I moan, loudly. Rubbing the sides of my turgid bloated balls as they continue to bloat and balloon bigger and bigger. They’re the size of watermelons now as they push against the palms of my hands. The feeling of holding two inflating flesh sacks filled with cum unbelievable, turning purple as the veins rise to the surface on my tortured sack.

STREEEEEETCH

URRRRRRRNG

My balls swell viciously with even more cum as I orgasm. Loosing the fight with my libido, my body convulses, however, nothing is coming out of my restricted dick. The cock ring forces it all to remain in my oversized nuts. Swelling to the size of pumpkins, stretch marks are streaking across the expanse of my skin. The hairless sack weeping cum through the pores as my body twitches and convulses. The skinny body before me flexing and contorting in pleasure as the constant weight of cum drags my balls half off the seat…. I go to stand up.

“Oh… fuuuuuuuuuuck,” I groan, the deep pulling sensation as I stand feels like my balls are gonna tear from my body. Another orgasm… “Oh.. no not another onennnnugh…”

GROOOOOOAN

BLOOOOOORCH

BLOOORP

My nuts swell outward like bloated balls connected to a water hose. They deform like a couple of water balloons stuffed inside my thinning sack. The weight is nearly unbearable as I panic. Pleasure taking over as another orgasm wracks my body,

“Oh god... when’s it gonna stop!” I moan, holding onto the sides of my prize-winning pumpkins.

Hands shaking, I grab for a tape measure and wrap it around each of my fat, overweight nuts. Each testicle surpassing 25 inches in diameter, they dwarf the width of my waist. My groin is filled with swelling testicle juices as wave after wave of orgasm washes over me. The constant kegeling and dry heaving of my cock is making my sack burn as the force causes my bouncing nuts to yank on the sack…

*POP*

“Fuck! My sack… its ripping apart…” I moan.

“Oh God! This is it… I’m gonna burst!” I back up slowly, my nuts slamming into my knees as a stretch mark tears open on top of the sack. This exposes the pulsating testicle to the open air as a burning sensation rips its way across my swelling, over inflated sack. My balls engorged, obese, cum sluts filling themselves up even further as my mind continues to look for the story being sent my way. That way I can finally remove this cock ring….

*PING*

“Finally!” I yell, the story coming through on discord. Steadily grabbing my phone and quickly yanking off the cock ring.

I start jacking off, hard! Pounding the hell out my fat cock as an orgasm builds. The pressure growing inside my sack as my balls go to release their burgeoning contents…

“Hurry… up… Can’t take… mm…much more cum,” I cry out desperately. I drop my phone as my balls let out a deafening squelching noise. A popping sensation rents its way across my balls as tingling spreads across the sack. They’re so thin, I can see the testicles through what’s left of the stretch mark scarred sack. The meat bulging through openings as my balls spring a leak…

SQUIRT

URRRRRRNG

A leathery whine belts from my sack as one last orgasm takes over my body. My balls, cords, and sack failing as I attempt to kegel. My legs wobble, jostling my balls as they visibly churn as they’re jostled from the shakiness and my repeated punching of my fists. Desperate to orgasm, every blow sends a shudder down my spine. My balls surpass the size beanbag chairs hanging low, grazing the ground. The bloated globes are rumbling loudly as they quiver. The meat I can feel tear apart from the inside as my cords feel ready to burst. A deep pain is building in my lower abdomen as I feel the cords begin giving way with a

SNAP

RIIIIP

POP

My sack tears up the center with a violent rip like a zipper, tearing along the seam of the sack. My balls drop as their bloated, engorged mass wobbles freely in the air from the recoil like a water balloon.

“UNNNNNGHUH!” I yell, the feeling of burning relief as my nuts, wobbling and jostling downward full of cum slam into the floor. Like a couple of over filled balloons they deform, collapsing under their own wait as the fluid rebounds within the balls of flesh…

SQUEEAAAAAL

BLOOOOOORPH

BLOOOOSH

KASPLORCH

The massive, still swelling nuts expand one last time with cum as they burst like a can of biscuits. Cum explodes outward in a violent wave, crashing into the floor as it splatters all over the place.

“Well, I knew I shouldn’t have edged so much... Those pills really did work well,” I moan, looking at the white mess all over the bedroom. A scene of white sticky goo dripping from the walls, ceiling, everywhere. My cock is still throbbing hard as I sit down to continue reading the story.
