I masterbated in my sleep!
A true story.
I love to masturbate, and a few months ago I decided to abstain from all masturbation just to see how long I could hold out. I held out for a month and a half. Then one night I went to bed and thought it to be no different.
Only, sometime about one or two in the morning I started sleep walking. I ended up getting my tube of lubricating jelly, lubing up good, and masturbating while asleep and it didn't wake me up until I rolled over on top of my tube of lubricating jelly, and orgasmed at the same time.
It made a huge mess all over my sheets. I had lube all over my fingers, and all over my penis. I also had cum all over my chest hands and penis. Luckily I do all my own laundry so I just washed my sheets the next day, and everything was fine. One experience I will never forget! It was also one of the best orgasms I have ever had.
