Three years into their marriage, Nao and Yusuke were living happily, even though they lived on a low floor of an apartment building. One day, Nao was invited to a party by Watanabe, who lived on a higher floor. Yusuke was reluctant, but Nao, who had some desire for a wealthy life, decided to secretly attend on a day when Yusuke would be coming home late... Although they lived in the same apartment building, Nao let her guard down while drinking in a "luxury" room with a completely different size and view, and they even ended up having sex... "I'll give you anything you want, so get your pussy out and get pregnant with my baby." A luxury room, presents, and endless sex... At first Nao hesitated, but Kokoro and body were taken over by the high-class men, and she became a slave begging for creampies...
