Rob felt odd. He entered the bathroom to wash the muscle stud that was Dave's pre-cum off his shirt. "Muscle stud? Why did I think that?" Rob wondered as he removed his shirt in front of the mirror.
"I should was that taste out of my mouth. What happened to Dave? And the office?"
He tried to picture Melanie, his girlfriend of the past three months, trying to banish the image of gay porn and anal sex from his mind. To his horror, he could only picture Dave and his furry partner, having sex in the open.
To his growing horror, Rob felt his crotch swelling. "What? No! Why is that turning me on?" He looked at him reflection and saw a beard beginning to form on his face. His bare torso also began to rapidly push out hair.
An urge to remove his pants overtook Rob. Unable to resist the feeling, he undid his belt and dropped his khakis and boxers. What he saw both shocked and amazed him.
His cock had grown to a length of 10 inches and his foreskin had grown back. Looking back to his reflection Rob saw that his beard had grown across his face and his chest was covered in hair. His cock stuck out above balls the size of oranges.
His change was not finished yet, Rob's temples were starting to show the points of horns and his legs were itching uncomfortably.
