Mike pressed his cock against Jeff's lips groaning in pleasure thinking it felt so good to have his growing cock against a pussy, even if it was fake. He was sure not getting anything from his girlfriend, but maybe when she saw his huge new cock he would. Without mercy he plunges into Jeff moaning out as he starts to pound his lips Jeff thinking that he could feel how big his cock had gotten.
His cock seemed to still be growing in size as well as he pounded into his mouth. He could taste how sweaty and dirty his cock was in his mouth. His precum was already leaking into his mouth too and it tasted salty and nasty. Nothing was worse than how stretched out he was becoming because of Mike's growing cock. He wasnt sure how big Mike would grow but he sure hoped his dick growth would come to a hault before he was broken.
Mike groans in pleasure as he bucked his hips harder and deeper into Jeff. His balls slapping against Jeff, they also were larger in size filling quickly with cum that was ready to shoot inside Jeff. Jeff wanted to scream as Mike's giant dick was shoved so deep into him. He was glad to feel that at least his dick stopped growing, but he was at his limit for how much he could take. He could feel himself bulging out thinking he would easily be ripped by Mike if he did anything too hard.
Mike cums hard moaning out loudly as he grips Jeff hard. He cums rope after rope of cum into Jeff. As he finishes he starts thrusting again, the potion making him want to cum at least a couple more times. He would be up with his fleshlight all night at this rate.
He sits down on his bed as he pumps Jeff back and forth on his cock. Jeff didnt know how much more of this he could take. He knew however that he didnt have a choice, he would be used as much as Mike wanted to use him. Mike cums again into Jeff his smelly cock shooting a big load into Jeff again. He could feel he was filled with his cum, some leaking out of him onto Mike's floor. Mike didnt seem to care as he kept pumping him on his cock.
