We're in the same math class and I've noticed that you always get good grades on your tests. I'm not so good at math so I was hoping maybe you could tutor me a bit? I promise I'll make it worth your while ;) After agreeing to help me with my homework, you take your cock out and I can't believe how big it is!! I grab it and start sucking it, slow at first but the more I suck it, I get faster and sloppier! Then I get on top of you and ride your cock, bouncing my fat ass on it over and over again. But wait, I need one more thing from you: I need you to cum inside me!
