Jake soon felt a massive wave of pleasure go through his body. His pecs bulged more underneath his chest plate, forcing it out. His arms bloated, grinding against the sides of his torso. His thighs managed to make his skin tight pants burst, revealing the comically covered manhood from his jockstrap. Even then that didn't hold. His cock grew bigger and weighed heavier making the strap droop till it snapped off. Jake started aging too as his face managed to grow a nice stubble of hair while growing a square jaw and deep voice. Soon Jake was pushing eleven feet, naked but still wearing his football helmet.
Soon all the other players started to follow up. Cocks bursted left and right. Chests bloated rounder and bigger. All the teens were soon grown men, bearing huge hard-ons, hairy pits, hard enormous asses, colossal arms, thick necks, gigantic thighs and deep moaning voices. The team gathered around naked admiring one another while wearing their helmets. Each of them started flexing and posing, rubbing each others muscles and slapping their hard asses. But it didn't stop.
Soon the whole team had another growth spurt. Orgasmic manly moans filled the stadium as the muscle jocks kept growing. Their cocks managed ten feet by the time they reach twenty feet. They were filling the stadium. Each player moaning, groping themselves and each other. Their cocks growing in between each others hairy pecs. Some flexed as they were turned on. They groped their meat more and more as they saw it tower, begging for more. Their arms pushing each other for room. They sweated and grew as the stadium lost room to contain the muscle giants. They fought for space as they grew into a pile of muscles, pecs, ass and huge cocks. The stadium contained an orgy of 100 foot muscle giants!
