We found out quite by accident our best friend was a Dom. I heard some loud smacking noises coming from the downstairs apartment we have in the house. Knowing she had a date (even though we were in a poly relationship but open) we knew she had a man in her apartment. We let it go for the time being. But one afternoon I didn't know her date had come over. I knocked on the door and just popped in. I caught them, him tied from the ceiling and she in a dom outfit. I excused myself and let them alone. That evening when she came to dinner we had a discussion where she revealed she had several pets that she humiliated, never fucked, but humiliated, spanked, denied orgasm, and such.
