Taking Free-Use Control of Bitch Step-Sister

Bitchy British step-sister Tamsin walks in to find her adult step-bro playing with toys. She mocks him mercilessly for not having grown out of it and ridicules him more when he insists that the toys have real power she should be wary of. As she scoffs, he waves a glowing toy in her face and she is slowly captivated and then transformed by a swipe of light. Now cable-tied to a chair with her legs spread, she still refuses to believe her step-bro has real magic powers until he clicks his fingers and she immediately becomes a submissive, obedient slut begging for punishment. He pulls down her top and slaps, pinches & gropes her pert natural tits. He pulls her panties to the side and rubs & slaps her exposed pussy as she moans. He commemorates their new power dynamic by writing "SLUT" on her chest with her lipstick and slapping her face, squeezing her tits, fingering her mouth and holding her eyelids wide open to put her in her place. The step-brother bends her over and with her big juicy ass right in his face, gropes and spanks her before smacking his dick on her soft ass cheeks and giving her a wedgie using her black lace thong. To complete her ass humiliation he pulls down her panties and spreads her ass cheeks wide open, asshole on display, and fucks her pussy from behind with the huge glowing toy. Next, he puts her on her knees and deepthroat fucks her mouth with the illuminated toy as she gags, drools and pulls ahegao faces. The step-bro applies nipple suckers to her little titties as his subby step-sis looks up at him. He finishes her slut training by wrapping her dirty lace thong around his big, throbbing dick and panty-wanking over her as she slaps herself, makes dumb eye-rolling ahegao faces and gives cum-begging JOI before he shoots his hot sperm on her tits and stuffs the panties into her mouth before snapping her back to reality.
