DASS-461 Waka Misono, a busty wife who goes to cuckold every day after falling to the back piston that penetrates her trainer's uterus

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 with the pleasure of having her uterus ejaculated! A big-breasted 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
