On A Business Trip and Sharing A Room With A Colleague!

I'm going on a business trip with my colleague Haruka, who has a boyfriend. But to a mistake I made on the reservation, we ended up in the same room. I was conscious of the fact that it was just the two of us in a closed room, but she was kind enough to tell me that it was okay if we slept in the same bed. However, I couldn't resist the sight of her lustrous figure as she slept defenseless, so I attacked her in her sleep! And what a surprise! She says, "Oh I wouldn't have totally done it if you told me!"
