A beautiful mature woman with an I-cup figure, Honami Hazuki, secretly got into the car of her affair partner. Honami, a married woman who is head over heels for the man, follows his instructions and hides 'tobikko' in her panties, and when she puts on a collar, she starts to look like a woman imagining sex with the man... The two of them went straight to a hotel, avoiding prying eyes, and fell into a relationship where they indulge in each other's bodies, away from their daily lives. Honami, as if to regain the 'womanly' self she can't find in her married life, reveals her animalistic face to the man, a face she doesn't show to her husband. On the other hand, for the man, she seems to be a convenient existence who can be called with just one phone call as an extremely convenient sex disposal partner. The two of them, who spend their days having 'raw creampie' sex, taking advantage of Honami's affection, are becoming a relationship from which there is no turning back. In the private open-air bath, a standing doggy style, and back on the bed, Honami, who is wildly aroused, is creampied deep inside her vagina and falls into a state of bliss... Ignoring Honami, who is addicted to this relationship and becomes sentimental every time they meet, the man's stance as 'my exclusive creampie pussy' remains unchanged. This convenient relationship of enjoying a beautiful mature woman in her prime as a convenient sex disposal partner will continue from now on!!
