FWB [MF] submissive girl goes all out

This happened years ago when I was in my 20s, I was friends with a smart athletic girl who played on my sand volleyball team. She was mid 20s, we were both single and ended up hooking up.
We were both pretty dominant people so a relationship realt wasn’t going to work, we tried but we ended up fighting a lot.
However we did have a good time in bed, so we decided since we both were single to keep that going.

One time during sex, a slapped her on the ass, she moaned and told me to do it again. That sort of led to a full over the knee spanking.
For someone who was as aggressive as she was, I never realized she has huge submissive streak. We started to explore this more and more, really pushing her boundaries to see how far she would take it.

One time when she came over I made her get completely naked on the front porch before I would let her in.

Another time when she was over in the afternoon, we were upstairs in bed about to engage when a friend stopped over to pick up some money I owed him. As I was about to give him the money I asked if instead of the money, he wanted to have a go with Julie.

He was pretty shocked but said sure. So I sent him upstairs. Told him to tell her I said it was ok.
I waited downstairs and 15 minutes later he came down, gave me a high 5 and said we even.

I went up and found her on the bed, a pillow over her face. She was a little embarrassed and ashamed. I was never more turned on… When she saw how excited I was she felt better and we had fantastic sex.
We used that as a common reason for me to “punish” her for being a slut.

I’m my opinion the ultimate was one time after sex I really needed to use the bathroom. I told her to get up and took her with me. Told her to get in the tub and knee down. Then I urinated on her breasts, belly and pussy as she touched herself.

Not long after she started dating someone and we cut it off. She ended up marrying the guy, he was sort of a whimpy guy, she told me she was by the far the dominate partner.

Everytime I see them together I picture her kneeling in the bathtub touching herself.
