This was one of the most intense sex feelings in a long time. I was thinking about getting off, and just kind of not sure if I was going to. I got that feeling like I wanted something in my butt. I gave myself warm water enema and that got things going and nice and cleaned out. Then I was looking at my toys and playing with a thin vibrator, about 2cm. The batteries were a little dead so it was not a real strong vibration, but I put it on my cock and it was awakened.
Then I put the vibrator on a holder thing I have and it was at just the right level so I could be on all fours and back up to it with my anus. A little lube and it was ready. I backed onto it and it slid in comfortably. I was on my hands and knees and just rocking back and forth slowly and looking at some lingerie ads. then I found the spot. By moving my hips in different directions and angles I could stroke my prostrate with the tip of the vibrator in all different directions. Best was to have it stroke it like a finger making the 'come here' motion, or the opposite of that motion. Just holding the vibrator pressed against it was good too, but the rhythmic stroking was better.
I got a huge erection, which doesn't always happen with butt only stimulation. My prostrate was tingling as was my whole cock and I started oozing out a lot of cum. I thought I would orgasm for the first time without touching my cock. But I had to do some stroking and then I came in a little black strapless bra I keep for that purpose. It was a really intense sensation. I think I'll find some new batteries and try that again right now!
