GF was sitting there about to pee, door open as most always, when I walked in to do the same. She looked up at me with her naughty smile and I immediately lost interest in peeing as my "flag pole" stood up at attention.
Kneeling down in front of her wedging in between her legs I pulled her towards me and entered her hot pussy just as it started to gush a strong flow of warm golden piss.

Maybe I'll tell more at another time as I hear the familiar sound of splashing bubbles.
