You then turn to find Nash shaking, then notice him getting a boner in his pants. You just stare, to watch Nash take his own penis out, as he starts masturbating with it, but then find that it was getting longer, while at the same time the ball-sack was getting bigger, and the entire thing was getting darker.
The extending stopped, when you find the tip of Nash's penis changing into something you haven't seen before. "Damn, this feels good every time a night like this happens," Nash comments, but then you see his pants ripping, as he unbuckles the belt. You then watch Nash's butt extend, and find that he was growing a long black tail, along with brown fur on his butt, while his legs also morph in his pants. Just then, as he takes his shoes off, you watch the fur extend down to his legs, that fuse into hooves.
As Nash's tail was now fully grown, you watch his butthole pucker, and become the same color as his testicles, then he lays down on the floor to continue masturbating. "What are you?" You ask. "A werehorse," Nash answered. "My look crazy, but that's what I am."
