Cock-in-pocket pants:

I've modified a pair of cotton pants, to let the pockets become an integrated part, of the 'build-in' panties.

The idea being, that if Domina wants to grab me by the balls, for either reason, she'll just put her hand into my pocket. *GG*

And here I've photographed the inside of the trousers, showing how the trick is made.

I have removed the front pockets, and sewn the panty-bag in its place, to let me insert my cock and balls, through the opening, that you see, at the bottom. The strip of black fabric you see at the back, is only there to keep some control over the bag, which can get quite 'live', as it is made from the same kind of fabric, used to make bathing-suits.
