DASS-703 | Miyu Aizawa, a big-assed wife who falls into ecstasy with her trainer's back piston that digs into her uterus and gets cuckolded every day

She resists the trainer's sexual harassment lesson by saying, "I'm a married woman!", but the muscle pistons bring her to a climax she's never experienced before! The back pistons are especially intense, and the pleasure of having her uterus drilled makes her sweat and squirt as she has a spasming orgasm! The big-assed wife, who has never been able to cum with her husband, cums again and again, and loses her mind when someone other than her husband pours semen (protein) into the depths of her vagina! Drowning in pleasure, Miyu goes to the gym to be cuckolded again today, ignoring her husband's worries.
