Mai Hanano is a devoted married woman who throws herself wholeheartedly into housework. Her impeccable modesty and innocence shine through—until an unexpected presence suddenly emerges, disrupting the harmony. Deep within her body stirs an extremely thick, rigid vibrator, pulsing intensely. As she moves her big, shapely ass, the vibe seems to vanish inside her, as if she's mindlessly indulging in its pleasure. One day, a repairman visits the Hanano residence. Entranced by her plump, round ass and full, soft breasts, he finds his desire impossible to suppress. When his work ends and he comes to report, he discovers Mai fast asleep, completely defenseless. Unable to resist any longer, he reaches out and touches her soft, fluffy buttocks, finally giving in to his overwhelming urges.
