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.

At first Nao hesitated, but her mind and body were taken over by the high-class men, and she became a slave begging for creampies...
