Use the diaper.

You know that you are expected to use your diapers. At least you don't have an audience right now.

You release your bladder and feel the liquid pool under your bottom. The padding grows thicker as it draws the pee away from your skin.

Looking down at your diaper, it is obviously wet. You expect Sarah and Tanya will comment on it as soon as they join you in the living room but they seem to ignore it completely. They just sit down and watch TV with you.

Over time the soggy diaper grows cold and uncomfortable. You wonder how long you're going to have to sit in it. Not that you're looking forward to Tanya changing it. That will be a whole new level of humiliation.
