The female teacher becomes a victim of a monster parent after a student's bullying incident. Her body is restrained in a Y-shaped spreader bar, bent backward with her joints tightly locked. Her soft physique is forcibly stretched, sinking deeper into a sea of pleasure. A fucking machine forces her legs into a 180-degree split, steadily thrusting into her widely opened pussy without pause. The pleasure never stops. She can do nothing but surrender her body, riding wave after wave of orgasm. This intense, erotic experience gradually takes control of her mind.
