I will warn you up front...this TRUE story involves my wife peeing.
Due to the birth of our two boys, my wife tends to pee when having an orgasm. I won't forget when I first found out that was a problem for her.
I had noticed when we resumed our love life after our second child, she was having trouble reaching orgasm. So I confronted her one night after she was relaxed. After some inital resistance, she told me how she was peeing or leaking during orgasm. I told her that I didn't care. But she began to cry and asked how could I!?
So I placed her on the toilet (naked of course) and began to play with her naked body. Her eyes, lips, shoulders, breast, kissing her. And I began to have my fingers follow my lips. But my lips couldn't reach her pussy and so my fingers began to do the work. As my lips went elsewhere, my fingers explored her pussy lips, caressing and eventually penetrating her. My wife likes it hard when I finger fuck her. Since I noticed she was wet and flowing, I began to go for it. I began jackhammering her pussy, the way she likes it. But I could tell she was resisting. But I whispered in her ear, 'Pee on me...come on...cum for me and pee' And she did. I could feel her pee squirting down my fingers and wrist and into the toilet bowl as her pussy clenched on my finger in orgasm. I was stroking my own dick and came on the floor.
We do it in the shower a lot now and on the toilet...and it is always very wet, the way I like it.
