Doesn't she have a girlfriend to help you realize this fantasy? I'd like to get into your wife, but my wife wouldn't approve. lol

The only threesomes that I've ever had were in my dreams, though I did come close to swapping once or twice.

All of our threesomes have been while we were very much wide awake!

I have been in a few threesomes over the years to say the least but not exactly as you described.

To that extent of my girlfriends from college use to love to get woken up or wake me up preferably with oral sex. 🌮 👅 🍆👅 💦. Back then both of us would have enjoyed the 3rd to heighten our pleasures.

....so what's in it for the third other than servicing you both, finding a third (unicorn) that's willing to have sex is your first step before you get specific

That's something that I have experienced and absolutely loved it. Many of my partners over the years, and I have screwed and had oral with another person in the room who is sleeping. They may have awakened and got a beautiful show too. A few got up and joined in as well. What fantastic fun! When you are both super horny, and also just don't care if anyone sees you nude, have the fun! Enjoy

Partner wants or has given 100% consent to waking her up sexually one day...
It's hot, the thought... But to do or attempt to do so feels kind of "weird"..
As in, what if she wakes up an is cranky 🤬🤬🤷 next minute it's a bit of a potential drama.

So it's difficult in A-wanting to do it but B-ing a little apprehensive.

I guess I could pre warn her night before.. but sporadic is so much hotter

I used to meet with a couple and stay overnight with them. I used the guest room, but it was made clear that if I woke during the night I was welcome to enter their room and play and fuck the wife.

One particular night we had been drinking and only had some foreplay before retiring for the night. I woke feeling horny during the night and decided to go to their room. The wife was a light sleeper and when I entered she woke up. I showed her my hard cock and her eyes lit up and she sucked on me at the edge of the bed while her husband was still asleep.

I started to fuck her and her husband woke up and was watching us and masturbating. She orgasmed and I shot my cum inside her. As soon as I slid out he slid into her and filled her again. It was a spur of the moment thing, but something I shall never forget.

I've done it several times back into the day when I was married. Wife would give me the ok to wake her friend up. Night of drinkin and nudity something was gonna happen. Miss those days
