A voluptuous housewife named Honda Sayume (age 48) hires a personal trainer to help her lose weight after being fondled by her husband during their workout sessions. However, when the muscular trainer starts touching her, she can't resist getting aroused! She asks him to touch her breasts, buttocks, and genitals instead. The trainer obliges, exposing her nipples and rubbing her clitoris while also performing anal play on her. As a sign of gratitude, she gives him a blowjob until he ejaculates, which she then swallows.
For the second training session, Sayume goes all out with her sexual desires, actively pursuing the trainer at home despite being married. They end up having passionate intercourse in the living room, ignoring her husband completely. In the third session, she cheats on both trainers simultaneously, enjoying multiple orgasms as she discovers her newfound love for sex.
