For me it is because I have wanted what I'm living for so long (even before I could define what it was I sought), I couldn't imagine doing anything to fuck it up. So yeah, I could pull it out and jerk it, but likely not get it back in ( have never tried and it's irrelevant). Or I dunno, maybe use a vibrator to get off and have a cage cummy, but again I wouldn't. When I came yesterday, as the torrent of mind bending, sometimes I think to the point of mind-breaking, sensations coursed through me, I knew the wait had been worth it. Every F'n second of it. Even as the last drop dribbled out and I knew I was going to be re-locked, I still thought it was worth it, and couldn't wait to suffer again. One of the best things about this site is that I know I'm not alone.
