New part-timer Sayama Ai keeps making mistakes, and I become so frustrated and aroused by her voluptuous body that I lecture her while desperately groping her breasts. Suddenly she snaps, calls me a clumsy virgin, and pins me down instead. She smothers me beneath her huge ass and treats my cock like a living vibrator, refusing to stop no matter how many times I cum. In front of the manager she remains a quiet married woman, but whenever we are alone she transforms and drains me relentlessly like her personal sex slave.
