Well I did try the sandwish bag trick twice and it just does not work. The stuff inside the diaper still manage to get inside the bag an on my penis and shaft.
I may try this again. However so far no luck. I did really enjoy the feeling of peeing inside the pad and feeling it totally swell up. I will say that tucked inside the pad one does get maximum use of the pad and it fills then when you sit down it squishes into the diaper. Pee again and it refills and swell. I did enjoy that.
