Just a quick post on this because it is something i’ve been thinking about. When i was first locked up i would have filled a device the size of a cb-6000 but i was put in a smaller device. At first it was uncomfortable, especially if i got hard. Most of the erection was internal because of the device. After a while that stopped but over time my cock must have become used to the space it had because on removal my cock just about filled the smaller device.
All that is perfectly understandable and over time it did start to get back to its normal size but i can’t help thinking that may not happen if it was on for a very long period of time, a few years for example. i’m self locked again until i find a new Master and then it will be up to him how and how long i am locked so i may yet find out.
i have discussed this shrinkage with various Masters before most of them seemed to think it was a good look for a slave, especially when combined with permanently stretched balls.
