I have always slept in the nude even as a kid. I hate getting tangled up in clothing in the middle of the night! A few years ago on a particularly hot summer night I awoke about 2:00 a.m. with a raging hard on. Lying on top of the covers there was a small breeze coming from the window that cooled things off a bit and created an eerie feeling on my cock. My wife was sound asleep and facing the other way. I figured if I got up I would wake her so I decided to take care of business as quiet as I could while still in bed.
I slowly began to stroke my cock about two strokes a second, this sounds fast but it isn't, try it! This was slow enough not to rock the bed and with the breeze blowing in it made for an incredible feeling. Stroking this slow is deeply relaxing and almost hypnotic at that time of night with your sleeping wife one foot away.
After about 20 minutes of this rhythmic stroking I had the deepest feeling of an orgasm coming on. As I came I stopped stroking long enough to actually feel the movement of my cum flowing up my cock! I am not a 'shooter' which has its benefits for clean up but I do put out a large load. After this deep orgasm I rubbed my cum all over my stomach and let it air dry. What a turn on! I lay there for another half an hour just buzzing!
Since that night I have done this many times. I think with it being in the middle of the night when you're half asleep and trance like, the thrill of possibly getting caught (haven't yet) and the slow stroking make this truly a unique jacking experience.
