When Erin and I were dating in high school, we thought at one point that she might be pregnant. We were actually trying to get pregnant and hoping she was. I was fifteen and she was thirteen. We went out and bought a pregnancy test and she came over to my house. We went in the bathroom together and I had her pee in a plastic cup of mine.
We dipped the stick in the cup and I sat the cup out of the way at the back of the sink. She turned out not to be pregnant and I scooted her out of the bathroom because I had to go. She protested about the cup of pee sitting there. I told her I would take care of it. I locked the door and went to the bathroom. My cup was sitting there on the sink filled with her pee. I was curious about tasting it because I had seen porn on the internet involving watersports. The temptation was too great and the opportunity was probably never going to come up again so I decided to try it. I picked up the cup and swirled it around... it wasn't very dark at all, almost clear and it only had a very faint scent to it, which I actually kind of liked. I brought the cup to my lips and took a sip. It was very warm, salty, and just a little bitter. I drank it all and set the cup aside, satisfied with being brave enough to try something I was curious about and honestly very horny after doing it. It felt dirty and I liked it. I would try it again if she were open to it.
I did eventually tell her about it after we were married. She was surprised but did not really say anything negative. She knows I get curious and want to test that curiosity from time to time. I enjoy pushing my limits and trying new things. She has been both supportive and accepting of me and my sexual interests and escapades, even when it's something well outside of bounds. When I ask her what she thinks about certain curiosities or interests, she almost always smiles and responds by saying, “Whatever floats your boat!” I do love that response.
After all this time… I still have the cup in my "Erin box" of things from when we dated back then. :)
