My senpai Kaoru, who took care of me after I got too drunk at work. But I was so drunk I couldn't walk straight, and Kaoru, worried about me, let me stay at her place. When I woke up the next morning with a pounding hangover, I saw Kaoru sleeping soundly in her underwear right in front of me! I couldn't help but kiss her as she woke up. During work, Kaoru was always so plain and reserved, but when it came to sex, she became so incredibly passionate, it was something I never knew about her.
