What I usually do, is to book her the night before so I'm sure to book her first. After making her come multiple times, she turns into a psychopath and gives me a very long, strong and risky pussy slide. It's kind of hard to explain, it feels like she's fucking me, trying to erase my dick with her pussy.
Although she loves it, she always complaints afterwards because she feels like she doesn't want to work anymore. Lol.
