You come into the kitchen while I'm working on my trigonometry homework, and I beg you to help me. I just don't get this stuff at all! You say you will, but at a cost. You know I slept with my step-dad, and so you know you can get me to do things with you, too. After a few minutes of pressuring me, I give in, and you demand to see my tits before we go any further. After you're satisfied they're up to your standards, I start fingering myself for you. But as soon as I've done that for a few minutes, I try to get you to help me with my homework. You won't let me weasel my way out of it - I HAVE to cum for you! So I finger myself again, moving into various positions until I cum for you!
