Asian women were crafted for omorashi, a sexual fetish consisting of the retention of urine. The woman might find this arousing physically or situationally, or might be the unwitting subject of the fetish in observers through needing to urinate but being unable to access an appropriate location to do so, maybe eventually giving up and urinating in public, or holding out as long as possible before wetting herself.

Anyways that is what asian women were designed to do.
