No Fucking Anyone Else But Me

Arin's overprotective, and his stepsister Monica eats it up. She waits till Leo's over for the game, then she comes in purring, sitting real close, fetching drinks, hanging on every stupid joke Leo tells. Leo's eyes bug out. Arin sits there white-knuckling the remote. After Leo's third time staring down Monica's cleavage like he's starving, Arin snaps. "Get the fuck out," he barks, shoves Leo to the door, slams it. Monica's pupils blow wide. Holy shit—her stepbro just claimed her. She teases him, calls him jealous, then slips off to shower. Five minutes later she calls his name through the door. "Towel?" Arin walks in and she yanks him straight under the spray, hot water hitting tile while she drops to her knees and gags herself on his cock, spit running down her chin. Arin grabs a fistful of wet hair and fucks her throat until she taps his thigh for air. She turns, palms the wall, pushes her ass back. Arin drives straight in. Her fat tits swing, skin slapping wet skin, water flying every time his hips smack hers. She's loud, greedy, creaming on him. They finish fast, towel off sloppy, bolt to the bedroom before Mom and Dad roll in. Monica rides him hard, then gets flipped on all fours. Arin wrecks her, pounding so deep she keeps cumming, legs shaking, every squeeze pulling another squirt out of her. Between moans she pulls off, licks herself off his shaft in long hungry strokes. Finally she cups his balls, strokes fast, sucks the head and coaxes thick ropes onto her tongue, across her cheek and over her fingers. Arin watches his stepsister lick the last drop off her wrist, grinning up at him like the cat that got the cream.
