A beautiful secretary from a business partner is confined and exposed to aphrodisiacs and trained in a sex scene

When I woke up, I was tied to chains. There's a man I don't know in front of me. Apparently he knows about me. A grudge? What? I don't remember... Oh... I can't put any strength into my body. And my body is incredibly hot. My body is weird...no...just touching it makes me feel like I'm going to let my heart go by...
