to have sex with someone while they're still asleep or drowsy.
In the early morning I will suprise my boyfriend with sleeping sex. I slide on his erection just before he wakes up.

what you give your woman using your morning glory
I woke at 4 am with a massive piss hard-on and slipped it into Nanci;she doesn't mind sleepy sex provided that you don't wake her up too much.

when you just can't sleep and you can't find anything better to do than suck on your lover's penis, but doing so gently enough to provide an erection without waking him up. Inevitably he wakes up but he's having such a good time he'll pretend he's asleep. If you look up he's got one eye open but may or may not continue to snore and may even shift positions to make things more easy to configure.
"so have you seen a doctor about your insomnia?"

"no, he said I should continue to provide sleepy sex until I pass out."
