Fucking My Physiotherapist

I've been fucking my married physiotherapist for two years now and its consistently some of the best sex I've had, and I've had a lot of women. We met when I went to her for a soccer injury and we were attracted to each other right away. We're both lean and athletic and its not uncommon for us to fuck four or five times per session. Her entire body turns a bright shade of pink when she comes. She's told me that she usually fakes orgasms with her husband, and it turns me on knowing she's coming hard every time I fuck her.
