Nathan Bronson, the stepbrother with a insatiable appetite, can't keep his hands off his naughty stepsister, Evelyn Claire. He watches her from his bedroom window as she sunbathes, her tiny bikini leaving little to the imagination. When she innocently asks him to apply sunscreen on her back, he sees his chance. He massages her shoulders, then lets his hands wander lower, cupping her ripe breasts and teasing her hard nipples. Evelyn arches into his touch, her breath hitching as he slips a hand between her legs, stroking her through her bikini bottoms. She turns to face him, her eyes heavy-lidded with desire. "Fuck me, Nathan," she begs, and he does, flipping her onto all fours and slamming into her from behind, fucking her hard and deep until they both cry out in release, their bodies slick with sweat and cum.
