Last night I awoke during my sleep. This was not one of the I gotta pee moments. I should note that this was during day 8 of my current lockup. I am still recovering from back surgery a little over a month ago and just restarting my chastity! I awoke to the feeling of my penis touching the end of the tube, I am in a Custom Chastity Leopard. The inside of the tube has a eggshell texture to it. I could feel the additional pressure as my penis tried to grow. I then got a little spasm and now I felt my penis move to touch the underside of my penis. It then repeated the cycle. I found this very pleasurable, almost like a mini orgasm, but without any emissions. This went on for quite a few minutes. This was a very pleasurable experience. While I have had similar experiences before, none have lasted this long or have the intensity that this one had. Has anyone else had similar experiences?
