Jake was starting to feel different in his four penises. It was a good feeling, and he knew what it was, but he was afraid to partake in it with four of the things! Though he realized, his libido had been multiplied with his penises, and he couldn't help himself. He touched one of his penises, a hardening cock, and shuddered with pleasure. He was a bit hesitant to masturbate, but his temptation was too strong "Oh, what the heck?" Jake grabbed his bouquet of dicks with both of his hands and immediately collapsed. falling on his butt. All of his penises sprang to erection as he fondled them in every way he could. He was overcome by countless sexual fantasies, and stared into the water beside him. He quickly scurried towards the water, dipping his face in without letting go of his penises, and took as many gulps of water as he could before he lifted his head out. He laid on his back, groaning and desperately trying to play with himself, when his four penises and eight balls grew out larger. He gasped, and immediately intensified his wonderful masturbation. His penises and balls quickly grew bigger and bigger, becoming ever more sensitive to even the slightest of sexual suggestion. It was not long before all of his dicks were a foot long and still growing! His balls were massive, pouring over his legs as he continued jacking off. He felt an orgasm coming on, and he was unprepared as he shivered and gasped for breath, twitching violently as if in a seizure, and he ejaculated. His four two-foot cocks started cumming by the gallons, leaving Jake in recovery.
