Nerdy Stepdaughter Caught Masturbating

Your A/C's a bust, house turns into a fucking sauna. Stepmom? Dead. You. Against the clock. Then your stepdaughter says she needs the fan. Ten minutes later you're pushing open her bedroom door and there she is, bare-ass naked, legs wide, middle two fingers working her slick little pussy in lazy circles. You just stand there with the fan, cock twitching like it's got a heartbeat of its own. She clocks the motion but doesn't stop; slows down instead, dragging those wet fingers from clit to hole in long, deliberate strokes. Eyes are locked on you now—horny and defiant. There's your invitation. She keeps riding her hand, panting soft as her hips lift and drop, sheets already darker under her ass from how soaked she is. Cock’s pressing iron against your zipper, no hiding it. She sees it, licks her lip. ‘Lemme see how big my stepdad gets.’ You unzip. The head’s wet, veins thick. She flashes you a smirk that’s half-wicked, half-challenge. ‘Wanna feel how hot I am before you stick that fat dick in me?’
