I meet my best friend's stepmother at the GYM and we end up fucking hard

I was training at the gym like I do everyday but this time I ran into someone I didn't expected: my best friend's stepmom! We trained together for a while and I noticed something on the way she acted that made me really horny: she was flirting with me! And I didn't lose time, since we were alone on the GYM she started sucking my dick and we fucked so good, the risk was amazing and I came on her big beautiful tits!
