I had a vanilla friend that told me he had heard that I was a Dom and didn't believe it. He came over one afternoon to visit let my slave know that he thought it was a pretty silly rumor. She asked me if she could go change and since she was in house wear with a long robe over her I agreed.
I figured she would come back in a skirt and blouse since I had always told her I would not make her behave overtly like a sub in front of friends and family. Instead she came back without the robe but with wrist and ankle cuffs on plus a heavy play collar.
She came to me and with her shelf bra on garter belt hose and her nicest set of high heels and asked if she could sdo or get anything for "her Master". I sent her off for beers for friend and myself and watched him watch her go for the beers. She brought back only 2 beers one for him and one for me. I was speechless and really not in control of anything as this all unfolded. She came to me and asked if she could sit I nodded. She sat by feet and laid her head in my lap and asked if she could do anything for me. Friend downed the beer quickly mumbled something about needing to go do something and she got up to open the door for him.
Once he was gone I ask what the hell was that about. She replied that she felt that both of us had been insulted and she needed to do something about it, since I couldn't.
Friend seemed to have new respect for us both after that.
