Stories featuring guys who have the classic “boytaur” configuration: muscular, youthful bodies with four legs, two in front and two in back—essentially centaurs but with four human legs (also called “humantaurs”, though boytaurs are usually young men). Most boytaurs also have four arms, and a large cock both front and rear. Particularly athletic boytaurs are sometimes called “jocktaurs”.
