Ben sat back, feeling relieved from his recent release. He was now a bit worried. There was still so much time, but what about Matt? Clearly he was going to change, but it was happening fast. Maybe he was devolving to catch up? He decided to wait and see.
Matt sat back, feeling strangely sore, but thought nothing of it. He didn't notice how bushy his brow became. He began playing the video game again. As he did, he felt his groin get tight in his pants. He had a strange urge to grunt, which he did. He didn't know why until he looked at Ben. He smiled, feeling like his mouth was slightly bigger, but didn't know what else to do. He itched so much....
Ben began to get worried. Matt was clearly getting hairier fast and his musk was overpowering. So much, that Ben began to tent again. Matt spoke, "Ben, me...I mean, I want to kiss you. Is that weird?" he said in a much lower voice. Grabbing his throat, he looked worried at his devolving friend and ran to the bathroom. A deep roar issued from it. "Ben, what you done to me? Rawr" Matt put his hand over his mouth, seeing the hair and scared.
Ben went up to Matt and embraced him. "I don't know, but I feel....a need. Grrr" While Ben was keeping his mind, his caveman urges were welling up as his snakey penis began to harden again. Matt looked at him, feeling his own body pop and change. "Me scared, Benny...rawr". He knelt down and began to suck on Ben. Both devolving friends began to growl, unable to control their urges.
Ben leaned over Matt and began having sex with him properly, seeing his friend change and go even beyond him in his devolution. "Ben, rawr...", Matt said. Ben had to get him out of there, but needed to satiate his need to mate.
Cumming together, both growled, but only one was able to talk afterwards. "Matt? Matt? How are you?", Ben asked.
"Me feel good", Matt said. Ben decided to go out to the forest so that he could finish his devolution. Perhaps when he finished, Matt would return to normal too...
