I thought he would still be asleep. I sometimes seduce my wife like that in my sleep. My subconscious is having an affair, and then I wake up and we are doing stuff. Best way to wake up. My wife has told me that sometimes I get all frisky, then run out of steam and flop back down snoring. There is a part of our brain that is supposed to keep us from moving around during REM sleep and when it falls down on the job you get sleepwalking.
