In our house "Italian Foreplay" (hey, you awake?) is not necessary. If I want some action I roll over and clamber aboard. All is good. She is always ready. Always. The sad truth is I turn her down a lot more than she ever has turned me down. I blame my age, poor physical condition and the lessened libido of a guy entering his mid-fifties. Once or twice a day is my max, and there are times I don't even do that anymore.
My experiences of waking up to stealth BJ's
Ditto for when my Lady finds something in the middle of the night that she can get ahold of and ride - that is fine by me. We tend to sleep au natural so we always are spooning skin on skin. Things come up that way, and apparently there are times that a dream erection is useable. I've been told that once I enjoyed getting a BBBJWS without remembering the deed. That seems like a story to me, I don't know how I could not remember such a thing the next morning. BBBJWSs tend to make me smile all day, actually.
The only rule my Lady insists on is that I have to perform such shenanigans before 4 am - she has trouble getting back to sleep if I heave away on her too close to alarm clock time, and is overly tired all day. I don't have any rules myself. If I get intromission or some oral play that wakes me and makes me groan with pleasure I'm a happy camper.
