Science class

I got to class a few minutes early. I sat at my desk and put my bag on the back of my chair. I remembered my cock, sitting between my tits and felt it hardening. I had some time to spare, so I pulled out my growing erection and began stroking it.

I put the head into my mouth and started to suck on it a bit. Eventually, I dipped my head down farther on my shaft. Soon, I was practically deepthroating myself. It was easy for a big-cocked futa like me. I was part of my school's gymnastic-fucking team before I my pillow-tits had been fully developed, so I was quite flexible too.

I had been sucking myself off for a minute or two, and people were beginning to pour into the classroom. Girls sat at their desks and walked around talking to others. There was the regular noise of discussions, jokes, moaning and the slapping of genitals. There were still six minutes or so left to the break so I kept up my autofellatio.

Finally, I felt my cock twitching in my mouth. I stroked it's length and vaccumed the head. Load after load of my own thick, white, delicious futanari cum came out of my cock and down my throat. I gulped it all down just as the final bell rang and everyone got to their spots.
