When I was in college a group of about 10 of us were partying in my small dorm room. We were drinking quite a bit of beer. One friend, a girl we'll call her Simonè, sat on my lap. She was very drunk. She had her arms around my neck being flirtingly amourous. I had my arms around her waist, more to steady her from falling off my lap than anything else. After 10 minutes or so she became rather quiet. A couple minutes later I noticed my lap becoming curiously warmer. Within a few seconds I began to feel the intense wetness of her proceeding to empty the contents of her VERY full bladder into my lap!
It was startling and I jumped to my feet, not recognizing what was happening. She slunk lazily to the floor. The rest of the room howled when they saw what had happened, both of our tight '80s jeans soaked from near the belt-line to mid thigh.
I sympathized with her immediately and announced loudly over the raucous din to the rest of the party animals that they needed to "move the party down the hall, NOW!"
They filed out quickly taking the beer with them. After they left I scooped up the sopping offender and laid her on the couch, tucking a few towel under her damp, shapely hips. I looked at her smiling and thinking,
"Aww, Sweetie, had I known what was happening at the moment, I would have held you tight and let you expell every last drop into my welcoming crotch. Then I would have sat with you cuddled on my lap until the the temperature became uncomfortably cool. Only then would I have discretely asked the room to leave with a finger to my lips and a "shhh."
I quickly changed and left her to sleep while I ran back to join the party. We were all friends, so we got a laugh out of it, including Simonè the next day.
Simonè and I became sexually intimate months later. We lightheartedly brought up the incident and I remember telling her that I thought it was funny and that it was even a bit of a turn on. She only giggled demurely. It never lead to anything else of the sort.
To this day I fantasize of a repeat performance, but in the nude savoring every moment of the golden lap shower.
