A guy I was hooking up with told me he really had to pee while we were walking outside about 15 min away from our houses. I spontaneously said he could pee in my mouth if he wanted to. He agreed and that was the start of us experimenting with pee. I got down on my knees and let him piss in my mouth. It overfilled and I let it drip down and soak my shirt. When we got back to his house I told him I wanted to have sex and pee on him. He then sat on the toilet while i sat on top of him and started to pee. He then inserted his dick and I continued to piss all over him. It felt so naughty I loved it. Next I wanted him to piss inside me and fill me up while he penetrated me. We stood in the shower and he first started peeing on the outside of my pussy and then slipped his cock in. I could feel the liquid filling inside of me. He then started to pump in and out. When he came out a flood of his piss dropped out of me it was so hot. We continued to have sex until he cummed and the mix of his piss and cum felt so messy and dirty I loved it.
