Trapped in a sexless marriage, Ryoka hires a young personal trainer and tempts him in tight workout clothes that turn transparent with sweat. Her heated body grows extra sensitive, and she drops his pants to take him deep down her throat, swallowing the heavy load he shoots there. The lesson continues in the bedroom, where he licks her hard nipples and fingers her soaked pussy until she convulses through orgasm after orgasm. Her trainer then gives her an especially deep workout and fills her with a thick creampie.
