My husband and I own two gyms. We are both personal trainers and coaches. The thing is that I have sex with heavy men behind my husband's back. I'm addicted to being humiliated and sexually used by these men. The heavier the better , especially if they are un showered. Yesterday was my first time being with two of them at the same time. It was completely disgusting and dirty. I can't stop thinking about it and hiding in the bathroom to masturbate about it.
