DASS-941 | Natsu Tojo, a beautiful-assed wife who goes to her trainer's house every day to be cuckolded, orgasms from his back piston that digs into her uterus.

She resists her trainer's sexually harassing lesson by saying, "I'm a married woman!", but the muscle piston gives her an orgasm like she's never felt before! The back piston is especially intense, and the pleasure of having her uterus gouged out makes her sweat and squirt as she convulses in ecstasy! The beautiful-assed wife who could never orgasm with her husband goes wild with pleasure again and again, and her sanity crumbles as semen (protein) other than her husband's is poured deep into her vagina! Drowning in pleasure, Natsu goes to the gym again today to be cheated on, oblivious to her worried husband.
