Chastity for big clitty girls

Hi girls,

Can anyone recommend a chastity device that is comfortable enough for 24/7 wear on a big clitty? Hard, it is 9 inches long and about 7 inches around. Soft varies, but at the smallest about 5 inches long and 5.5 inches around. It doesn't fit at all in a CB6000 even with the largest ring and spacer sizes. I tried a couple of extra large CB6000 knock-offs and it is possible to get it in after an ice bath, some lubricant and some pinching, but it protrudes out of all the little holes and chafes if I wear it more than a few hours. I am not a masochist, just want to be totally focused on giving pleasure and receiving anal pleasure. Suggestions would be appreciated. XOXO
