The sleepy fetish appeared early on, before my sexual ones. Always preferred gentle and romantic KO's and carries. No rough stuff like choking or hits on the head. Once the girl is out and carried off, I would first slowly remove her boots and expose her pantyhosed legs and feet. Then on to other things.
a few years ago my ex wife got in a fight with another woman. she was knocked out with a jaw punch,i fainted and we were both carried to seperate bedrooms. since then i've had a fetish about her being knocked cold by another woman
