As i said in another post. I obliterated my CB6K a couple nights ago with a massive erection administered by my lovely KH/Wife. The thing practically shot off me like it was spring loaded. Luckily I had purchased the fort and had been altering it slightly to make it more comforatable. So when my KH was pissed i just broke the only chastity device in the house, she was please to learn i had a backup, one that won't break if i get overly aroused. So it's been locked in place since then and is doing very well. Better than my previous trial runs for a few hours here and there. I smoothed out any places that had hard edges or made it uncomfortable. It's still not as comfy as the 6k but thats the price you pay for security i guess. I love the weight even though it makes my balls ache a little. I never forget i have it on. I used the 2nd and 3rd smallest rings behind my balls and the small spacer between the rings and cage. I found there was a bit of play still in it so i placed a rubber o-ring next to the spacer. this also keeps the spacer from sliding right off when the cage is removed. I also put 3 smaller o-rings on the pins. it keeps everything nice and tight and i also like the look of it. im posting pics in an album if anyone is interested. I'm pretty stoked and have that same feeling as when she first started locking me up. kind of nervous and excited and really wanting to please her. Hopefully in a few days everything will still be good and I won't have to experiment any longer with the rings and spacers. so far, so good!
