Submissive Step-Daughter Seduces Her Daddy's TA

Kira Noir works hard at everything. She earns perfect grades. She also earns every drop Ramon feeds her down her throat when she gags on his cock, and every inch he drives into her ass when he flips her over and fucks her like a toy. He uses her until she shakes and thanks him. Kacie Castle walks in and turns the whole thing upside down. She’s the professor’s step-daughter, she’s bored, and she refuses to sit still for lessons. Ramon puts Kira in charge of tutoring her. Kira sulks, so Ramon strips her, lashes her to a frame in leather cuffs, and canes stripes down her thighs and tits. A heavy flogger follows until she’s trembling and wet. He leaves her bent and straining in a strict position until she begs to obey. Once she’s broken in, he lets her grind her soaked cunt on the toe of his shoe until she cums on the floor. Then he bends her over the desk, slams into her ass, then her pussy, and she promises Kacie will pass every test. Kacie spits on that promise. She spits in Kira’s face when she tries to keep her on task. Kira snaps, pins the girl, and spanks her bare ass until it glows. She grabs a cane and lays sharp lines across Kacie’s thighs and cheeks, then straps on and rams her open asshole until the girl is drooling and shaking. Kacie spreads wider, fingers her own clit, and cums from the beating and the pounding. When she’s finished she drops to her knees and buries her tongue in Kira’s ass, then her cunt, licking until Kira shudders and comes on her face. Ramon walks in, sees the red welts and the mess, and decides neither girl can be trusted on her own. He strings Kira into a tight shibari backbend, face trapped between Kacie’s legs. Clothespins bite Kacie’s nipples in a zipper she has to hold with a textbook. Ramon quizzes them while the zapper jumps from skin to skin. Every wrong answer earns a shock. Neither girl is allowed to come. Kacie finally earns the zipper off and screams as the pins rip free, but the pain pushes her over; she cums hard on Kira’s tongue. Ramon frees them both and fucks their mouths, then their holes, switching between ass and pussy while they ride him reverse cowgirl, sharing his cock and his load until both are shaking and used.
