Kim told me the dirtiest sex story the other day. She loves to tell me all about her naughty sexcapades, she knows how hot they make me, and entertains herself watching the big bulge under my pants grow as I make some excuse to go to the bathroom and masturbate. In this story, Kim was having a naughty lesbian threesome with her classmates in the empty classroom during recess. Imagine what would happen if they get caught!
