Chitose is a full-time housewife whose sons have already grown up. While she spends her days busy with household chores, she also has a bit of free time on her hands. It's not that she's unfaithful, but it's been quite a while since she last had sex with her husband—so long ago that she can't even remember when. In truth, Chitose has been constantly sexually frustrated. She decided to participate this time because, after seeing her well-toned son's body following a bath, she suddenly felt an intense arousal, realizing "This is dangerous." At that moment, her panties were already stained with arousal. With her voluptuous body overflowing with pent-up desire, juices gush out heavily as she screams in pleasure, "Ah—No, I can't—", "Too good—", thoroughly enjoying passionate, hot sex.
