She waited for me to fall into a very sound sleep (About 2 hours after I went to bed.), then came in a started to suck on my cock until I got aroused and woke up to it.  We then got fully involved.

It was really quite delightful.

I don't think I would want to have sex with someone who is unconscious.  That's sort of like necrophilia.

I'll leave that to Alice Cooper.

The request was for me to pretend to be asleep during the entire session. It was actually kind of sexy because even though i was having physical urges to respond I had to fight that and not move or make noise.

Then after waking her, she fell asleep again, mid BBBJ. That wasn't planned though, and she wasn't on any drugs that I gave her. Posted a thread about it last year.

I was living with a school teacher who would climb on my morning wood while I was sleeping and ride me before going to school.  Good times!

I did see a guy with this fetish. He had many excellent references, so he wasn't a concern that way. How it went was I left the door unlocked, and pretended to be asleep in bed, he came in, put his envelope down and woke me up, so to speak.
