Yamada’s company organizes a mandatory fitness session at the training grounds where Hitomi proves she's just as dedicated to working out as any man. Deeply admiring her physique and spirit—especially her massive bust and ample behind—Yamada strives tirelessly to earn her favor. However intense efforts can lead to exhaustion; after pushing himself too hard during the grueling workout routine alongside his colleagues and superiors alike,
Yamada collapses from fatigue and retreats to rest in his room. In a moment of clumsy desperation fueled by admiration for Hitomi’s curves (big ass/big tits!), he mistakenly stumbles into her private quarters. Catching sight of her revealing lingerie hanging out on a rack, he is instantly mesmerized. Unable to resist the temptation presented by her intimate apparel, Yamada snatches up her bra/lingerie piece and begins masturbating furiously while staring at it.
What follows shatters his internal panic! Instead of being furious or embarrassed, Hitomi calmly discovers his secret act. To Yamada's utter surprise, instead of reprimanding him, she grants him permission—allowing him to continue his self-pleasuring session right there in front of her! This intimate allowance sets the stage for much more exciting moments with this stunning Japanese woman.
