She resists her trainer's sexual harassment lesson by saying, "I'm a married woman!", but she experiences an orgasm she's never experienced before due to the muscle piston!The back piston is especially strong, and she has a convulsive orgasm as she sweats and squirts due to the pleasure of having her uterus ejaculated!A big-assed wife who has never been able to cum even once with her husband goes crazy over and over again, and her rationality collapses as semen (protein) from someone other than her husband is poured into her vagina!Drowning in pleasure, Miyu goes to the gym today to be cuckolded, despite her anxious husband.
