I was hog-tied on my knees, blindfolded, gagged, and left that way for a while while he sat in a chair and observed me. When he was happy and I was untied (and extremely sore), I had to write an essay on how I felt.
It took hours to do, because I could not sit comfortably, my legs were so sore, my arms were shaking and I was in mental turmoil.
Obviously I wrote something right, as we were together nearly 7 years (he died).
