A For Anal

Mark flunks Trinity on purpose. She owes him now, and he wants more than an A. He ties her wrists, straps a ball gag between her teeth, and clicks the current on. Every jolt snaps her body tight. When the pain blurs into heat, she opens wide for his cock and swallows until spit strings her chin. He turns her over, spits on her hole, and sinks in. No warm-up, just thick inches stretching her ass until she shakes around him.
