I don’t know how it happened! I went to the gym, and when I came back, I had a cock! It just…. appeared! At first I’m pretty nervous to show you, but before long, I can tell you’re pretty excited. I’m not sure how long my cock is going to stick around, and I don’t want it to go to waste, so I suggest we try pegging. You agree, and we waste no time getting into it. I start out on top, then decide I want you to bounce on my cock. I lie back and tell you to sit on my cock, slut. You immediately respond to that, so I lean into it, calling you my bitch and encouraging you to bounce on my cock like the little cockslut you are until you cum all over your stomach and I fill your ass with my cum.
