Fail to convince her you weren't hunting for cock

Stacy gets mad all over again when you try to explain what happened. "You expect me to believe you just somehow ended up blowing a cock in an alley accidentally?" she asks. "That's the fucking dumbest excuse I've ever heard! If you're gonna go hunt for dick to suck, at least have the decency to own up to it." Just then there's a knock on your front door. "Good, they're here," she says. "Now we're gonna find out the truth about you, cocksucker."
