Jeff wasn't sure why he was so aroused by this man. He was average looking, 5'9" or so, dark features. But he had to have him. As he approached and they explored each other Jeff's pleasure centers were working overtime. The man fell to his knees, taking Jeff in his mouth and then rising up he turned and led Jeff to his goal. This was something he'd never thought about but it felt incredible. He furiously met the other man thrust for thrust and as he came saw the other man was to cum too.
Taking and holding the man as he came Jeff was shocked when instead of cumming the man yelled a primal scream of pleasure and exploded into a thick white goo. Covering Jeff from head to toe he was able to quickly identify it as what it was, cum. Shocked yet oddly not surprised Jeff stood there in post-orgasmic bliss. As he did the cum began to be absorbed by his body until all that had touched him was inside. Jeff then started to feel hot, very hot in fact as his muscles cramped and his bones felt like they were breaking. Pain, such as he'd never known racked him as he saw his skin turn a darker color and his arms and legs shrink. His hair fell out and was replaced by a darker shade and dick shrank ever so slightly.
Finally the pain stopped and Jeff was able to stand again. Looking in the mirror he saw he now looked like a cross between himself, the first guy who was beer and the second who was cum. "So, I absorb people," he thought, surprisingly calmly. "It probably didn't hurt the first time because I was liquid when it happened."
Not sure how he felt about it, he grabbed the towel of the man from before to at least cover himself. "I have to get out here before someone else comes down," Jeff thought. Finding a pair of shorts and a t-shirt that was close enough Jeff left the house, not sure of where to go but knowing he had to avoid other people as much as possible or risk have a repeat occurrence.
