This was something I heard in more recent times, when I had a vague idea of what went on when men and women ‘did stuff’ (following the famous VHS ...ape in the sex shop). I didn’t want to give it too much thought but when you hear something you don’t understand, there is a natural curiosity, and initially I associated it with the fact that sometimes I’d ejaculate very quickly in my underpants seeing something nice or hearing something very sexy – raised skirt or lots of cleavage, or Miss Melanie. I followed her instructions and sat on the chair with my legs apart, facing the TV. Within minutes my hands were tied behind me and my ankles were tied to the front chair legs.

I'd do anything. Apologies and pleas for forgiveness tumbled from my mouth again, but she just ignored me. She demanded that I show her what I did, show her how I made myself cum with her panties. It was a humiliating idea, to be observed doing my perverse little ritual, but I would have done anything then if I thought I could save.
