Going through the image folder, I don't see her fucking in the office. There is a scene in the office folder, but it is of the night event.
There 2 scenes that lead to sex with her...
1. BikeSex: Get a ride from her after the night is done or call her to pick you up after being arrested (Take a few times)
2. NoRideSex: I believe this is labeled in the office part, but it is a night event. Just stay in the area and not take the ride. She goes from kissing you to having sex. Again after a few times.
In the office, there are only HJ, BJ, and weekend cunni
