A dimly lit study room transforms into a den of debauchery as the horny student, left alone with her stepbrother, can't resist the temptation. She leans over, her tongue darting out to taste the tip of his cock, already leaking pre-cum. She sucks him hard, her head bobbing up and down, her hand working his shaft in tandem. He grabs her hair, guiding her, his cock hitting the back of her throat, making her gag. She loves it, her pussy dripping with excitement. He pulls out, flipping her around, and fucks her mouth from behind, his balls slapping against her chin, until he cums, shooting his load down her throat. She swallows every drop, licking her lips, eager for more.
