Kana is my junior, a beautiful, charming colleague. Kana often makes mistakes at work, and I often help her, and it's the same today. After helping Kana finish her work, she invited me to drink with her. Maybe because I drank a little too much, Kana was drunk and didn't know anything, and now I also missed the last train, so I had to take her back to the hotel. Looking at the beautiful colleague lying on the bed right in front of me, I couldn't resist and grabbed her. While I was acting, Kana woke up, she panicked and stopped me but to no avail. After finishing work, I was thinking about apologizing to Kana when she suddenly tried to fuck me back! Not only that, but throughout that night, Kana hardly gave me a second to rest! My sperm was drained, I was exhausted and unconscious from time to time...
