While resisting a trainer's sexual harassment lesson by shouting 'I'm a married woman!', I experience an unprecedented orgasm from the muscle pistons! The back piston is particularly intense, with a sensation like my uterus is being sucked out, causing me to sweat and squirt in convulsive ecstasy! The big-breasted wife who never climaxed with her husband is now screaming in ecstasy, having another man's cum (protein) injected deep into her vagina, causing her to lose all reason! Envying the pleasure, Kana ignores her worried husband and goes to the gym to get fucked again today.
