Yuna Ogura plays a cosmetics company manager who has to share a hotel room with her adult subordinate during a business trip. She lets her guard down because he is a virgin, only for him to suddenly attack her and creampie her repeatedly. She becomes hooked on his relentless deep tongue-kissing, and they keep fucking all night. He cums, immediately slides back inside, and repeats the cycle without end. Her insatiable subordinate defiles the pussy she had reserved for her boyfriend with his tireless virgin cock.
