Stepdaughter's Seductive Intervention Saves Stepfather's Marriage from Brink of Collapse

Hey, I'm back. What's with the early return? Did you bail on your plans again? The math teacher cancelled, citing some obscure holiday, so I figured I'd come home. Yesterday was a holiday too, or so I thought... Anyway, I was thinking of taking my girlfriend out to the movies. Oh, you mean that girl you're always sneaking around with? What's her name, huh? Don't play dumb, I know all about your little trysts. You're not exactly subtle. Go hit the books, kiddo. I'm not in high school anymore, I'm in college! We don't do homework, okay? Your mom and I foot the bill for your education, so show some respect. I pay half, by the way. Look, I've already made plans, so... Fine, study first, then you can go out. You've been cooped up all week with your girlfriend, it's time for some fresh air. Can't I just take a walk? You've been grounding me all week! School comes first, kiddo. You can't just screw around all day... I mean, I'm not screwing around, I just want some freedom! Go to school, then you can have your fun. Where did you even get that from? You don't even know who you are! Do your homework, kiddo. First off, what's with the chicken comment, and secondly, my mom's libido is none of your business...
