Mikity-sensei is an online personal trainer with 98cm hips! I asked her to train me in person, which was a bit of a stretch! I couldn't contain my excitement at the sight of her big ass and got a full erection! "Erections release testosterone and are good for your muscles." Then the teacher straddles me and the sex workout begins! Her big ass pounding me into the cowgirl position, taking me past my limits, is so erotic that it makes my dick throbbing hard! I shoot multiple times and she laughs, saying, "Your dick will probably be sore tomorrow."
