Please don't tell step-mom and step-dad about my terrible grades...You decide not to as long as I do whatever you say. Starting off slow, you ask to see my ass and to spank myself for having such a bad report card. Then you get more and more carried away with what you want from me for you to stay quiet. You start getting me naked, making me suck your cock and then, no matter how much I beg you not to, you take your little step-sister's virginity
