Your step-father has had no luck getting through to you about your bad grades. He never punishes you and he never rewards you. That's about to change. If you don't improve your grades, I'm shipping you off to reform school. But if you get them up, I'll let you jerk off to My big tits. Yeah, I know you've been into Me ever since we met. So go ahead, whip it out and stroke to step mommy's tits. Get better grades and you'll get better rewards or else it's off to reform school!
