Ok, I am going to preface this by simply saying that I'm a little kinky, but not too far out there, and relatively new to sexual experiences, but Ill try my best to tell my experience.
A couple nights ago, my fiancee and I were in the pool at the hotel we were staying at. She wanted to go back to the room and said that we would shower together, and that if we hurry up, so could pee on me (before we had sex)! At that instant, I pretty much jumped right out of the pool and began drying off! We finally got each other all dried off and began walking back to the room. On the way there, she said she had to pee really bad! We had some trouble finding our room because the layout of the hotel was super confusing. She began to waddle a bit the closer we got to our room. At one point, she stops and goes "Hurry up, I really REALLY have to pee!!!" Not long after that, we found our room. We got in and tore off all our clothes. She rushed into the bathroom saying "I gotta peeee!!" Her full bladder had already gotten me turned on, but she sat on the toilet, and pee started gushing out before he butt even hit the seat. I put my hand between her legs so I could feel the hot pee pouring out of her! It was so hot, both in temperature and in sexiness! her gushing stream didn't last long, and the last few dribbles came out. I took my pee-covered hand and rubbed it on my dick and a little on my chest. This always gives me an INSTANT throbbing erection! I know she has a small bladder, which I find super sexy! I asked her if that was all she had, and said yes! We both stood up, and I looked into the toilet. Her pee was so pure and clear!! I turned on the shower and rubbed my dick in between her butt cheeks and gently spanked her a couple times while the water was warming up. She let out a couple moans, so I bit her neck (something she likes very much). We jumped in the shower and felt each other's skin! I told her I wanted her and that we need to hurry up! I washed her and she rinsed off, then we traded places and she washed me and then I rinsed off! I think its so attractive, getting to wash each other! We then got out and dried off! I opened the door, and ran to the side of the bed. She met me on the bed, on her hands and knees, with her butt facing me! I fingered her for a bit and then we did it from behind. I got on the bed, and had her get on top of me! She put my dick inside of her and f***ed me so passionately. I played with her boobs a bit and left some good scratch marks on her back! I asked her to tell me about how badly she had to pee, and she replied, "I had to go pee so bad! My bladder was so full!!!" I tried not to come as I teased her about her small bladder, and she said "I can't help it; I have a small bladder! It's so tiny," She stopped talking, and before long she orgasmed. Afterwards, I had her lay on her back and I asked if he wanted to keep going. She nodded her head 'yes', and I got on top. It wasn't long before I orgasmed too, just thinking about her pee desperation and her showering with me made me cum so easily!!! I cleaned up and snuggled as she fell asleep in my arms!
