We walked into the cabin and decided I should ask him what his name is. "So, I guess we should introduce ourselves", I said. "My name is David and my buddy here is Jack. What is your name?", I queried. He stated his name was Ross. "So, Ross, do you like other guys?", I asked him. Yeah, he replied. I can swing both ways. "Well, after a session with us, I think you'll only be swinging one way", I told him. The pheromones coming off of Jack and myself were very strong and I could see that Ross was definitely getting aroused. I walked over to him and wrapped my arms around him and rubbed my crotch against his. I could feel his cock hard against me and Jack walked over and starting shoving his tongue down Ross's throat. Ross moaned in pleasure and soon the three of us were on the bed, naked, and going at it. Ross had my bear cock in his mouth and was sucking me for all he was worth. Jack was working his tongue over Ross' body and was soon slurping down Ross's 8 inch meat. Ross had enough of my precum inside him that the changes began. I could see that blonde fur was starting to grow on his chest and arms. Soon, it was spreading to his back and shoulders. His ears were becoming furry and his gut was beginning to grow. As Jack worked on Ross's cock it was becoming thicker and longer and his balls were enlarging and becoming covered with thick blonde fur. He was going to be one handsome bear. My cock was ready to explode and I knew I had to have that ass of his. I flipped Ross over on his expanding stomach and started to lube up his furry ass with my precum. I shoved the large mushroom head against his virgin hole and started to push. Ross moaned with slight pain and then with pleasure as my bearcock slipped inside of him. "Yeah, fuck me", he said. "Fuck me good and hard". I complied and shoved my cock all the way home until my furry pubes rested against his ass. I then began a slow methodical motion. Knowing I was rubbing his prostate and giving him pleasure. It didn't take long and I came and came in his hot tight furry ass. Ross moaned slightly and I could see his belly and ass growing larger and his hands and feet developing pads. I knew he was one of ours. Jack sucked him off until he came, getting a huge load of bearcum. Ross was now one of us and ready to go out and find more "volunteers" to join our ranks.
