David shakes his head, "No.. this isn't right. You need to go back to the clinic, see if the doctor can fix you two. No one will believe who you are, how are you going to live."
Eric shrugs, "I really don't care, I still love Linny.. er.. Lenny. In fact, I think I might love him even more now." Lenny gets up and whispers something into Eric's ear. "Of course I don't mind. It'll be fun to watch."
David looks up to see the two looking right at him, licking their lips. He panics and makes a dash for the door, but Lenny catches up and wrestles him to the floor. Lenny sits on David, smiling hungrily at him. "You know, this cock is new, and I still haven't really been able to use it. I think I want to fuck you up the ass. You'd enjoy that wouldn't you?" David shook his head from side to side, but couldn't keep his eyes off Lenny's body. "I see how you look at this body of mine, you want it." Lenny reaches down and rips off David's shirt, running his hand through David's already hair chest he smiles. "Besides, I'm curious how you'll look too."
David shivers, unable to resist any longer. "Fine, I want it, give it to me." Lenny stands up, Eric positioning himself by the door, so he can watch, and keep David from escaping. David just begins to pull off his pants, fondling his seven inch erection as he looks at Lenny. He rolls over, sticking his hairy ass into the air.
Lenny kneels down, grabbing David's hips in his hands, he moves his 10 incher to David's crack, rubbing his cock back and forth between the hairy cheeks. David just gasps slightly at the feeling. Lenny draws back guiding his cock to David's hole and thrusts in burying down to his balls in one thrust. David squeels, biting his own arm to keep from screaming in pain. Lenny begins to rock back and forth. "This is what it feels like for a guy? God! It's fantastic, all this pleasure concentrated on one spot." He reaches around and grabs David's cock stroking it as he pumps his ass. Lenny's new organ quickly reaches climax and fills David's ass full of cum and serum. The feeling driving David to his own climax.
Lenny pulls back, sitting down on one of the beds, watching David like a hawk. David's cock almost instantly begins to grow, swell from seven to nine to almost a foot long hard, his palls swelling to the size of oranges. His organ begins to become even hairier, a thick bush growing up.
His hairy gut shrinks away into a six pack, the hair growing into a thick carpet, hiding the muscle underneath. His pecs swell out into massive plates of muscle, the dense hair thickening and spreading, covering his shoulders and moving to his back. His arms and legs begin to swell with muscle making him look like a bodybuilder, the hair grows up and meeting with the rest of his body hair as it thickens. His beard begins to grow out, becoming full and bushy.
David stands up and flexes in the mirror. "This is.. GREAT!" Lenny and Eric admired him, he had hair pretty much on every inch of his body, his abdomen, chest and crotch looking like he had a black shag carpet on. Turning to the other 2 he smiles, "I have an idea."
Eric tilts his head as he looks at his roommate. "What?"
David smiles. "The serum is in out cum, right? How about we spike some of the school's water with it? Might dilute it a little, but it could be fun." Eric and Lenny smiled, a bunch of muscular hairy men walking about might be fun. Even if they aren't as muscular and hairy as the original three.
