All the characters in this story are above age of 18 and all the sexual encounters were consensual.
I'm M (32) straight. This is the real story of how I discovered pee fetish, couple of years ago, when I was with my exgf (29,F).
Now I've been familiar with pee/water-sports fetishes. The source of course being porn. The first thing I saw was squirting videos and that seemed very intriguing. It then led to solo pissing videos and then self pee and golden shower, pissing on various parts of your partner etc. While it was fun watching those, it always seemed like a thing that's to be enjoyed by watching it being performed by the porn-stars. There was no literal appeal of doing it as it seemed rather gross to actually try it.
Fast forward to my ex gf, things changed. She was horny as fuck. I am always hesitant to initiate physical contact as I'm kind of shy. In our relationship, however she was the one who initiated the physical relationship, that too with very loud and clear demands. This part is important because this gave me a lot of excitement and also I felt the freedom to do whatever.
We were having rather colourful sex life. Although super horny, she wasn't really the one who had any ideas about different things to do. She would always rely on me to explore new things. Apart from lot of sex, the only other thing we would do was sexting.
As an adventure we first tried some car fun. She would touch me while I drove and then came hand-jobs in car. She was still hesitant about blowjobs especially about prospects of me ending up jerking off in her mouth. That changed over the period of time. She became more receptive to blowjobs after I started giving her warnings before cumming.
I, however have huge CIM (cum in mouth) and BJ overflow (Love to see my cum dripping off of her mouth as it overflows!) fantasies. I took a very slow and patient approach towards it and I would cum during BJs without warnings on very few occasions. She would quickly move when I'm about to explode and that would kind of ruin the orgasm. Over the period of time, I got her comfortable enough to even swallow my cum. (That's the story for some other time!) The good part was, she wanted to do it coz it excited her to be able to pull it off.
We were doing everything we could try and things looked great. Halfway into our relationship, there was a time when she had taken a vacation from work for 15 days and went to her hometown. It was of course going to be tough for both of us to survive without steamy sex. We would do the sexting and video-calls etc. but it was very limited due to lack of privacy at home. Most we could do was talk on calls. All the lewd lusty thoughts exchanged at night.
On one such night when we were talking (not even sexual talk, just simple talk), I heard some noise in the background which felt rather peculiar. When I asked about it, she laughed and said she got up and went to bathroom for peeing and the noise I heard was that of her peeing. The sound of her pee stream got stuck in my head and I kept thinking about it for a while.
