F for Fucking

"I've always been a good student who got As and Bs, but there was one time I almost failed a class because I got an F on an important test. Every time I tried to study for it I ended up fucking my study buddy. Every study session, we would say that this time we would really study, but my pussy would always get wet and I wouldn't be able to concentrate. Then we'd start tickling each other or touching each other and it would be too much to hold back. He would start fingering me or rubbing my pussy from outside my underwear and I would lose control and need to be on his cock. Luckily I was able to do extra credit for the class and pass with a C. That was the only C I ever got in a class, and while that kind of bothers me, it's also a nice little reminder of all the fun I had."
