Ok, so it was a normal lesson in geography, ever thing is going the same as it normally does. I looked up at the front of the room and saw my Geography bending over to get something of her desk. But what she didn't know was her boobs was very visible when she bent over and I saw almost everything (apart from her nipples and bottom of her boobs). I instantly got a hard penis and if someone wasn't sat next to me I probably would have put my hands in my pants and wank.
When I came home from school she was all I could think about. For the next three days I masterbated to her every night and I can tell you, they was the best masterbations that I have ever had.
