A 38-year-old married woman, Shiori Adachi, hires a personal trainer out of her own selfish desire to get close to a young man's body. She seduces the young, physique-focused trainer by letting him touch her body directly and showing him her naked form. While learning about body improvement tips, she casually touches the trainer's body and ends up touching his genitals too! She sucks on the trainer's enlarged manhood while completely naked, her voluptuous body on full display, until he ejaculates. During training, she keeps touching his genitals, making them bigger, and then takes him straight to sex! Unable to resist the temptation of the soft-bodied married woman's advances, they end up having an affair. Getting fucked makes her breasts and stomach jiggle, driving him wild with excitement! When another trainer arrives for her next home workout, she immediately starts demanding sex from him, neglecting the training altogether and indulging in a sex-filled session.
