Sai resists the trainer's sexual harassment lesson by saying, "I'm a married woman!" But she experiences an unprecedented orgasm from the muscle piston! Especially the back piston is intense, with a sensation like her uterus is being sucked out, causing her to sweat and squirt in spasmodic ecstasy! The big-breasted wife who never climaxed with her husband is now screaming in ecstasy, having other men's cum (protein) injected deep into her vagina, causing her to lose all reason! Lost in pleasure, Ayumi pays no mind to her worried husband and goes to the gym again today to get fucked.
