Derek tried to pull the sock off of his python cock, but it was on too tight and was still expanding! He noticed his balls were still growing larger too - probably because they were inserted with his cock and wouldn't stop growing until his cock was taken out of the sock too.
Derek felt a pulling at his groin as his sex organs grew larger and larger. Then he felt his body compensating for the extra weight there with new muscles growing to support it. His legs were now spread, his balls too big to hang between them - they were the size of basketballs now! And his cock was 3 feet long and thick!!! Maybe if he tried to think of a sexual turn-off it would shrivel enough for him to pull it out. But even though he tried, the pressure of the sock still impossibly intact and stretched to the hilt around his mega cock was too stimulating. The tighter the sock got, the harder his cock got. And the larger it grew. Finally the sock could hold no longer, and with a loud rip it split open, its tattered stretched remains falling to the floor.
Derek gasped, breathing heavily. His cock ran across the small bathroom floor and leaned up in the corner of the wall... it was easily 8 feet long and considerably thicker than his torso at its broadest point. His balls rested on the floor in his now king sized nut sack. These nuts looked more like two extra super large beach balls. Derek's mind raced, wondering how he was going to get out of this situation. Eventually, someone would notice he was missing, and would check the bathroom... eventually he would have to come out, except now he would need a couple strong men to help him lift his massive cock and balls out. He wasn't even sure if he would be able to get his balls through the door.
The thought of being discovered with his new massive genitals and ending up on the national news and the subject of scientific inquiry both horrified him and made him more excited. His cock throbbed, jerking in the corner, and he could see his balls tighten. He was going to cum, and he was helpless to stop it.
His cock bucked, and GUSHED! He screamed as the power of this massive orgasm overwhelmed him. He couldn't even think, his whole existance was orgasm.
Several minutes later, Derek rested panting against his own massive balls. His cock had started softening, but it wasn't much smaller and wasn't going to get much smaller. He couldn't think, couldn't speak, the pleasure had shorted out his higher brain functions... he was little more than an animal now.
Someone knocked at the bathroom door. "Derek, are you in there? It's Stan Marsden." If Derek knew how to think and remember, he would have recognized the voice of the book chain's district manager. "Derek, you shouldn't leave the store unattended like this. Derek?"
Derek drooled, letting out a moan.
"Are you ok?" Marsden was clearly getting concern after hearing the moan.
Derek moaned again, completely enwrapped in the afterglow of orgasm, practically oblivious to the voice of his district manager.
"Derek, it sounds like you're in trouble, I need you to answer me or I'm going to have to call for help and break the door down."
Drool. Moan.
Marsden decided it was time to take action.
