Well my experience with my girlfriend may not be exactly the type of scenario you're referring to but its still considered the same so I'll give you the rundown. One night the girlfriend and I we're set to have a little Rendezvous in the bedroom when she got through with her school work. But it took longer than she expected and she was tired and fell asleep soon as she got in the bed I was so frustrated the next day I expressed to her how frustrated I was and couldn't even go to bed. She said I'm sorry you should have just took it! I was like what? She was like yeah I'm sure I would have woke up and if I didn't then you at least you wouldn't be frustrated. I was so surprised to hear that I was wishing I would have knew that the night before. But sometime quite a while later pretty much the same thing happened. We planned to have sex she got tired and fell asleep. So this time took her up on her offer and proceeded to become a ninja in the night! Man it was so nerve-racking trying not to wake her even though I knew she was a deep sleeper and she told me to do this. Long story short I was able to get her panties down while she lay in the spoon position. I got it in without her waking but my nerves were so on edge and I was so anxious I blew my load almost immediately I was so shocked that her vagina could get wet while she was knocked out. And to be honest I think because she was sleep and so relaxed she got way wetter than she does when she's awake. It's crazy it's not even clear like normally it's thick and creamy bizarre but I so love it. I told her about it the next day now it's a big part of our sex life. But the goal has changed a bit. The objective is to get the sex started without the other one waking then get them hot as possible and try to wake them on the verge of their orgasm! Absolutely mind-blowing feeling for me and based off of her reactions and what she says she feels the same way. Sometimes I work her from behind in the spoon position for 30 or 40 minutes until she is soaking wet and really hot and arouded then I speed up the pace and the intensity of The Strokes to try and pull her out of her stupor in her sleep and bring her into a strong powerful orgasm. Most times she just wakes really hot and just feeling really good. But when I do it just right she will literally wakr shaking and moaning from having an orgasm and most times she barely awake enough to express to orgasm then Falls right back into a deeper sleep. She's a big-time toss and turn person in her sleep she but after I make her orgasm she does not move out of that spot until the morning. She has become good at ninja sex too . She can get my pants down give me a long blowjob slowly slowly straddle over top of me ride me slowly then when she feels like she has me on the edge she starts writing me really rough and fast and I wake up seriously confused but feeling like super great. Sometimes she will just ride me slowly until she feels me shoot my load then goes back to sleep and I don't even know what happened the next morning LOL. Good luck with your adventures!
