I've experimented with anal masturbation in the past but it never really did that much for me. The mental 'nastiness' factor was more exciting than the actual physical pleasure I received. I've inserted various objects like hairbrush handles and once tried a vibrator that an ex-girlfriend had left at my place. Even though it was a small vibrator for a pussy, it was way too big for for my ass.
A few weeks ago, I was playing with a well-lubricated length of hard plastic rod. The rod is smooth and about 3/4 inch thick. After sliding it in and out of my ass for a while I left it in and began to stroke my cock, making sure I left a couple of inches outside. I was lying on my back and noticed that as I moved my hips around, the rod would press against the bed and apply varying amounts of pressure in my ass.
That was when I got an idea. I got the vibrator, turned it on and placed it on the bed between my legs. I positioned the protruding end of the rod onto the vibrator and just about blew my mind. The male g-spot definitely exists.
The sensations were incredible. The vibrations transferred through the hard plastic rod and deep into my ass. I found that by varying the downward pressure of the rod onto the vibrator and clenching or releasing my ass on the rod, I could vary the intensity of the sensations.
I went completely wild and found myself gasping and moaning uncontrollably. I've had some incredible masturbation sessions in the past but this was way beyond anything I've ever experienced. It was truly a mind-blowing experience and now I can't get enough of it.
