GF refused then changed her mind

I asked my girlfriend to let me watch her pee. I told her I wanted her to hold her cunt lips open so I could see her do it. She said that was weird. So I showed her a couple of porn videos of women pissing. She watched them and said it kinda turned her on so we went into the shower and I fingered her cunt for a bit and she jerked me and then she said she was ready. She put one leg up on the side and I crouched down and then she did it. It flooded out of her and as she was getting done I started to rub her clit. When she was done she bent over and I rammed my cock in her doggy style and it only took a couple of minutes until I came over her back.
I think we are going to do it again tonight.
