From as early as I can remember, my ass has been very sensitive. When I was in grade school I used to get a huge hardon feeling my jeans rubbing my ass cheeks just walking between classses. I always loved touching my ass and sticking things in it more than touching my cock. And now, all these years later, it still holds true. I can still get hard and cum laying in front of a mirror or webcam watching myself play with my ass. In fact, I find it very hard to cum without some sort of anal stimulation.
