Saki, 28 years old, married her husband who was a co-worker and started a family, but she returned to work to pay for the purchase of an apartment. The manager Tabuchi, who has had his eye on Saki for a long time, plans a business trip to Kyushu for just the two of them. Unable to disobey her manager's orders, she goes on a business trip with him, and on the night after a business meeting with a business partner, Saki is forced to drink alcohol at the dinner table, and for some reason she ends up passed out... ``It's the prey I was aiming for...I'll entertain you until morning.'' A night of humiliation in which I was raped and made to cum over and over again by my boss who I hated to death.
