Mason Former college track star bound on sybian made to cum.

Mason used to run track at college, all muscle and medals, now she runs nowhere fast. She's strapped bare-assed to the sybian, thighs spread, wrists yanked behind her back, ankles cinched to the frame. The saddle hums to life beneath her, climbing fast. She grits her teeth and tries to lift off, but the rope holds. The first wave knocks her forward, and the second drags a raw scream up her throat. Sweat shines on her flat stomach as the machine pulses again, harder. Her hips buck, trying to twist free, and fail. Every jolt sends a fresh shock straight through her clit; her breath catches, breaks, catches again. The vibrator doesn’t pause, doesn’t care. It drags another orgasm out of her, then another, until her curses melt into one long moan. Her legs shake, muscles locked tight against the endless climb. The ropes creak. The machine keeps grinding. Mason has no choice left but to cum, again, and again, until nothing else fits in her head.
