My First Wet Sex

My girlfriend wants to be my fiance, and get married. She is slim, hot and beautiful. Sex is pretty vanilla, though she really moves, talks, bucks back at me, tells me to fuck her, changes positions, and will occasionally take it in the ass, which I love, and always has an open mouth. But anything else she shows no interest. In 3 years have only gotten her to pose for nudes for me to enjoy one time, and she was drunk as hell then. Don't get me wrong, I will probably marry her, however; I have interest in other sex acts.

I travel a lot in my work, and last week I hired an escort, not just for sex but to hang around, eat and drink with me, and then let me watch her pee and poo. She was really into it, and not just for the money, she asked if I wanted to get more "involved" with it and came by every night for free. She peed and pooed in front of me, at one point in the tub and sat in it while I kissed her and sucked her tiny little titties and rubbed her crotch to orgasm. At which time she got out of the tub, with it all over her ass and let me have her ass to cum in. I peed on her, she peed on me, she even drank my pee, and I sucked her pussy, which she called her c**t, right after she peed and got a taste of her. We went out to a park, in the afternoon and she stripped naked, bent over a picnic table and let me fuck her with some people watching. She paraded around the riverfront with her dress opened up all the way in front.

I like the kink, I like the less than normal sex, but I know my girl will never go for it. If I ask, or demand, I think she'll break it off, but . . . I almost have to do it now.
