All My Wife, All My Slave

My wife came to me with a strange admission that she wanted to be my slave. She had always been a submissive in bed, but this was a new, strange development in our lives.

Put your hands on the desk. You need a little more, something secret, so you know you're a slave."I pulled a black Sharpie marker from the desk drawer and carefully wrote SLAVE in block lettering on her right buttock."Is that really necessary?" she asked looking over her shoulder as I worked. I saw that now familiar look of conflict on her face, half excited and half disgusted at herself."Yes. Very.
I expect it to be there tonight when you get home. Now get dressed and get to work." I patted her left cheek and sent her on her way. Even though she protested, there was a grin on her face. She liked to be treated this way and I was happy to do it for her. After a grueling day's work I got home and showed Sheila the chains that I had made for her. That picked up her spirits a bit and she immediately wanted to try them out.
Before I got home she had gotten out the red leather cuffs but waited for me to put them on her."It's better when you do it, " she told me. "I like being locked up by you."
