The fifth installment features Rifo Shishido with huge tits and ass! She resists the trainer's sexual harassment lesson by saying, 'I'm a married woman!' but experiences an unprecedented orgasm from his muscle piston. The back piston is especially intense, giving her a sensation like her uterus is being sucked out, causing her to sweat and squirt in convulsive 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, Rihō ignores her worried husband and goes to the gym again today to get fucked.
