When I open your report card I'm not pleased. What's with these terrible grades?! Did I raise a boy who's only good for one thing? I really should put parental controls on your computer. I know that instead of studying you're just jerking off. When you tell me how often you do jerk off in a day, I don't believe you. I mean, you'd have to be really horny to be cumming that much. When I try to call your bluff by demanding that you masturbate right in front of me, you shock me by getting your cock out and stroking. Things get out of control and next thing I know I'm showing you my tits to help get you hard. Well, that's okay, so long as it doesn't go any further--but it does. Do you want to fuck step-Mommy, step-son
