And after their clit is stiff and their pussy is dripping wet, I roll them on their side and fuck them from behind while they have an orgasm in their dreams. Then I leave; they have never wakened, but the next day they tell their best friend about the "amazing dream" they had. Maybe this is how the stories about Incubus and Succubus got started? I should describe in greater detail about what I am thinking while I am doing this.
I am worried she will wake up, and trouble will ensue- but it is my fantasy and so she will do exactly what I hope she will! That worry is why I would not try this in real life. While I am caressing her I am paying attention to her physiology, to find what works best for her. Once I get to join in, I am just enjoying- but also imagining what my cock is doing, and believing that this is pleasant for her: moving everything around and stretching her vagina somewhat, and her cervix, and of course indirectly stimulating her clitoris, or reaching around to stimulate it directly.
I read someplace that anything you can do with a tongue can be done better with fingers- but I am not so sure of that, and anyway-fingers can't taste. I suppose I did not include any oral stimulation because the fantasy arose from a frustrated attempt to actually try something like that (not with a stranger who was asleep!). I suppose someone who was drunk might not wake up if you cranked her legs apart and got your face in there- but I am pretty sure most women would wake up.
What does any man think about while having sex? I would probably know that if I ever had sex, but I just write stories and wish someone would read them and get so hot and bothered that she decided to see if I could put my mouth where my money is... or is that the wrong saying? Anyway there is a saying that is perfect for this situation - but I don't know it. Maybe the guy who got upset that I misspelled Tuscon in another story will write in and provide the saying: or is it "there's a sucker born every minute".
