Game With a Classmate Ends With Fucking on Her Parents' Bed

Two classmates turn a boring afternoon into a game, and the loser has to pay up. She loses, and the payment happens in her parents' empty house, door unlocked, nobody home to interrupt. She starts with a sloppy blowjob on her knees, then he returns the favor with his tongue between her legs until she is wet and shaking. He bends her over the bed her mom sleeps in, spreads her legs and fucks her from behind, then flips her onto her back and pounds her pussy in missionary. She climbs on top and rides him, tits bouncing, moaning loud enough for the neighbors to hear. No condom, no hesitation, just hard fucking on the sheets, and she keeps her legs open through every stroke until he pulls out. It ends with a cumshot across her chest and stomach, both of them out of breath and laughing on her parents' bed, listening for the front door.
