I got there a little later than I planned; traffic was bad, and I had slept in. A was ready for me, and not particularly upset. She gave me a large glass of water, and offered me the chance to use the toilet. I declined; I was sure I would be fine.
She lead me to the bedroom; on her bed was a leather blindfold, an adult diaper, and what looked like a dog's choker leash in smaller scale. Handcuffs, too, but they were not standard - the connection between the cuffs was of some kind of cable, and about eighteen inches long. There was a box on the floor; it had holes on its side and its hinged top, and the top was padded.
She motioned me to sit on the bed, and put the blindfold on me. From this point I had no real idea what to expect. She kissed the nape of my neck, and pulled of my shirt. I felt a clasp fasten about my right hand, and the she pulled it gently behind me. Then the other clasp fastened about my left hand. Once I lay down, I wouldn't be able to move my hands. They were comfortable, all things considered.
I felt her undo my belt. She told me to stand up, and I did. She stripped me naked, socks and all, and I felt what I knew was the choker fastened about my balls. It felt like a rather intricate operation, but she took care of it quickly. Next, I lifted my leg and the diaper went on.
The she said, "We're going into the living room," and after a few seconds, took my hand. "Lie down," she told me. I felt terry cloth beneath my hands. "Lift your head a little." I felt her slide something behind my head; pillowed, contoured, a neutral, plasticky smell. I then felt an excruciating tightening in my nether-regions. She said, softly as ever, "You know what to do. If I don't think you are pulling your weight, I'll give you a little reminder like that. If you slack off too much, I have a riding crop within reach, and you are going to have some bruises to explain to your wife. When I close the box, you won't be able to hear so well. Depending on how I feel, you may not always be able to breathe so well, either - but the air will always come back. As you probably guessed, you are wearing a diaper. You aren't getting up until I I am done with you."
Then I felt a gentle compression around the sides of my face; I must be inside the two-holed box. She then tied my feet to something, which gave me a minute or so to get used to the feeling, and the lowered her now-naked body onto the padded top. I had never seen her nude, and I wouldn't today, either. I relished the feeling of vulnerability of being naked while she was dressed, and of being blindfolded when she was unclothed. She smelt fantastic. She had finished a light work-out shortly before I arrived, and hadn't showered. A healthy, musky, sexy scent wafted through my nostrils, and I was instantly (and uselessly) hard. I gave myself over to what came naturally.
