This what the school told you to do

She looks at you a bit annoyed but just sits down on your lap your cock smushed in between her ass cheeks like a hot dog. You feel so good you start to wiggle and press. She doesn't really notice until you accidentally cum on the butt of her leggings. When she feels something wet she knows what just happened. She looks at you with a look of discussed but before she can say anything you tell her that you didn't cum on her legging and she totally believes you and just sits there until class is over. You leave class and the rest of the day goes smoothly. During lunch you talk to your friend about the sleep over. You think to your self and remember that your going to sleep over at his house. Then you think about his hot sister. His sister has a fantastic body she is very toned and has C cup breasts and a big athletic Bubble butt that is just sexy as hell!
