You get to fuck your stepsister when you find her bad report card

You sit down on something and when you pick it up you find its your stepsister's report card.....and wow such bad grades! haha wait till the step parents hear about this. But she catches you with it too quick and gets really annoyed when you won't give it back. but then she turns on the sweet switch and starts being super nice! and sexy! wow she is hot, she's got huge breasts! and she wants to suck your dick! no wait she want you to fuck her right then and there. she wants your big hard dick to go in over and over into her sweet tight wet pussy......
