Years ago, my FWB at the time came over and spent the weekend with me. Saturday night we went out for drinks and were feeling no pain when we got home. We had amazing sex and went to sleep.

I woke up relatively early Sunday morning, realizing the bed was absolutely soaked. I have a waterproof mattress protector because my ex was a squirter, which I loved. Anyway I didn't think I'd been that drunk the night before.

I woke her up and when she realized she was marinating in a lake of pee, she started apologizing profusely and stripped the bed to wash the sheets. She explained bladder control was a side effect of some meds she was on. While I blew it off as no big deal, She was mortified, and left pretty quickly afterwards.

Ever since then I've fantasized about it happening again, but we just stay wet and have some wild, pee-soaked sex. Or just drinking a ton of water and wetting ourselves or each other on purpose while fucking like horny rabbits. Mmmm!
