Huge desperation piss; wetting my leggings with a full bladder! After holding it all day I just can't help myself!!! So desperate I hold It as long as I can while I wriggle and moan trying to keep it in before I get so helpless that I make a huge mess in my leggings!!! Soaking them completely with my huge bladder full of piss before I pull them down to masturbate in the mess!!!
