Put sleeping pills in the water, the boss forced the secretary to have sex at midnight

I thought that going on a business trip with the department head that I hated the most was the worst thing ever, but no! The client invited us to dinner, so both of us missed the train back to Tokyo. We had to stay in a temporary room without air conditioning. Even though I really didn't want to, I still had to share a room with this department head for the night. He started drugging me and forcing me.

He used some photos of us having sex to threaten me, making me serve him. Despite feeling humiliated and hating him, the intense pleasure he brought me made me climax again and again...
