Alright, so I was failing class again, and I knew it would take more than my cock to get Ms. Starr to raise my grade, so I got this brilliant idea. Why not bring my girl along with me, she likes the muff, it would be perfect! So we go to class and there she is, I start talking to her but all she can do is stare at my girlfriend. She says for us to meet her in the teachers lounge and when we get there they start kissing. As I slide my cock in her from behind she muffles over my girl's pussy that I get an A+!
