When I was a kid we spent our summers at a state park in the Poconos in Pennsylvania. The lake water was almost always cold and I discovered how wonderfull it felt to pee in my trunks and feel the warmth spread out around my crotch. I would purposly drink a lot before we went swimming just so that I could experience that sensation.
I never stopped enjoying that sensation whenever I could, but never did more than that until I was an adult. After a tour in the service, I lived with two Marine buddies while going to college. This was the early 70's.We caroused a lot and shared female fuck buddies. One of these women, Mary, was a regular encounter, either as a group or singly. I was at her apartment one night, busily munching on her tasty quim, and she had an intense orgasm. In addition to her usual wet flow I felt a squirt of a different kind of fluid go into my mouth. Gentleman that I was, I didn't say anything about it to her, not wanting to embarrass her since she had just squirted pee into my mouth. But on the other hand it made me so hot that I raised up, put my cock into her, and came after just a few strokes. That was the start.
More to cum.
