Have you tried using an inflatable butt plug? I have a couple of them. A small and a large size. The large size is wonderful. I'll insert it in me as deep as I can and then put on some tight, vinyl boy shorts. The shorts keeps the plug inside me. It cannot cum out. Then I'll pump it 12 or so times. It gets so big inside me I can't stand it. It makes my bowels move but the plug has no where to go. The feeling is like an orgasm. It brings me to my knees and makes me scream. I'll then walk around the house with my plug it and wearing my vinyl shorts, stockings and a skirt. Every few minutes my bowels start up and it stops me in my tracks. I have to grab on to a chair or a railing to keep from dropping to the floor. And then I moan and scream. My partner was going to call 911 to get me help then first time she witnessed this. I highly recommend it!!!
I was able to get my machine out and get fucked last night! My partner allowed me to So I was able to play with out sneaking or having guilt. It was fantastic and well needed. I got fucked so very well. I love it!
