An Unexpected Sex Change

He pulled away and asked if I was ok.

I nodded my head and gave him a little smile.

I clenched my teeth and shut my eyes tight. He put his tongue back in my mouth and grabbed my chest again. Finally, he slipped all the way in and started thrusting. Slowly at first. It burned a little, but it wasn't all that bad. I expected this to be much worse. Then he started speeding up.

I felt my breasts moving in the rhythm of his thrust. I grabbed both of them. I needed to grab something.

He leaned down again and kissed my chest as he thrust. It started to feel good. I couldn't understand how that could feel good? That's supposed to be so painful and wrong! No guy should enjoy that!

As he went faster, I felt better and better. My penis was harder than it had ever been and I could feel the precum sliding up the shaft of it. His giant cock was pressing against the insides of my ass. It was like nothing I had ever felt. Nobody told me this could feel so amazing!

I lifted my legs without thinking. He put his arms under them and held them up. That put him deeper inside. The feeling was almost euphoric. I started to get light-headed. I didn't want this to stop, as I'd never felt anything better!

He said he was getting tired. I let him pull out, but couldn't let it end there. He got on his back and I mounted him cowgirl-style. He reached up again for my breasts and held them as I slid his dick inside my, now loose, hole. I rode him as hard as I could for as long as I could. My hard penis slapped against my stomach as I rode. He grabbed it and began to play. I was loving every second of this.

After a while, we switched positions again. I got on all four and he thrusted himself inside me once again. I thought I was going to cry from how amazing it felt. My emotions were more mixed than I'd ever known.

All of a sudden, I felt it. He wrapped his hand around my rock-hard cock and it was like I was going to explode. I let out a loud, girlish shriek. He hadn't even started jerking me off. My crotch got warm. I could feel it in my asshole and in my stomach. The semen started to rise up through my penis and it shot out of me so hard, some of it landed on my hands.
