I'm Fingering My Trainer

I'm screwing my trainer I've been training in swimming for a while now, and I have a pretty good trainer, I won't give her name because she's not abundant. We used to go train at the KDT pool on Thursdays afternoons, where she worked as a lifeguard. After finishing her work shift, she would join our training. After it was over, I asked if I could take her home. It was very hot and after showering, we drove back in the car with very little clothes on. On the way there, she put her hand on my thigh and looked at me eagerly. While driving, I started rubbing myself and got hard. Since I had very dark windows and it was almost night, I asked her to suck me off while I was driving. I didn't want to come yet so I could screw her properly when we arrived. When we got there, her partner wasn't home from work yet, so we went up to the apartment. The heat was total, already in the elevator our hands were going and coming. We entered and rolled around on the couch and floor. We were all sweaty but well heated. I put her over a table and sucked her pussy and ass good, which had intentions of filling it. But as a good servant, I started screwing her hard in four, Booty paradita, and with my finger relaxing her asshole. When I was already hard, I held the cock well and let her take it slowly into her. When she reached the bottom, I grabbed her hips and started pumping. I couldn't hold on anymore and ended with a final thrust in her ass, then slowly pulled out to see my cum dripping from her. It was fantastic. Now every once in a while after training we have some barbarous ejaculations.
