It was over now for both of them. Whatever was going on outside the room didn't matter, what brought these two men together didn't matter. All that existed was their communal growth, and they both enjoyed it. While the smaller man planned it from the beginning, the homeless man was so addicted to his growing muscular frame and erotic thoughts that he no longer felt captive. He wanted to stay, he wanted this other man, he wanted the messiest muscle-fueled rampage to ever exist.
Those thoughts weren't his alone. The captor let out a moan as his cock burst from his underwear, muscles rippled and exploded again, and all of his clothing fell to the ground. Two horny growing muscle giants are all that remained in this room. The lights started to flicker as the power struggled to maintain both of these men. But he didn't think the power was needed anymore. As long as he had his muscled beast at his size, he could grow to any mass.
