My first pissing sex experience

When my wife and I both feel kinky, we have sex both wearing varying fetish outfits. I absolutely love these special occasions, sometimes in a hotel room, mostly at home.
In most cases we're both in latex or vinyl wear, also we put pvc bedsheets on the bed to add some more fetish feeling. I love to feel the material on my skin.
As my wife squirts occasionally when being fucked or fingered hard, the waterproof bed cover is very useful... When she squirts while my cock is in her, there is always this short moment when I can feel the warm liquid pour out of her.
One day I felt like she can't stop splashing which definitely increased my exitement! It felt like I got my short spurt abaout ten times or more. Suddenly she said, smiling:
Sorry, I have to go to the toilet, I really have to pee, cant stand it any longer. I'm awfully sorry. But maybe there's a second option, what do you think? Should I just let it flow?
I instantly got hard as hell and started again fucking her like creazy. We kissed intensely at the same time when after only some seconds I felt it: A warm gush pouring out of her cunt, wetting my cock and legs and forming a warm puddle under out bodies.
I exploded in an enourmous orgasm, having experience something unexpectedly intense. After that we lay in the warm wet for a while, both sure that this has not been the last time.
