Weird sex SeXStoRY

My girlfiend and I have always taken things slow. Mostly petting and missionary sex. I have never been brave enough to discuss my fetiish with her. One night after she got somewhat d***k we both crashed at our bedroom. Towards early morning before sunrise was my queue. I removed her panties slightly and inserted my morning glory erect cok up her ass. At first I thought of simply shafting her. Also, I rememebered the reason I woke up was due to urge to pee. There was this moment of trepidation and I decided to pee right into her. It took quite a bit of control to get sexually erect penis to actually pee without loosing erectiong fully. I started, the pressure built and I released very slowly. I could see the expression on her sl**py face. Then she suddenly woke and I have asked her to stay calm and keep control of her bowel. She did not argue much because of the hangover she was combating at the time of this event. Once I filled her up, I slowly removed my cok. Some of the liquid did try to get out during exit which was wiped off immediately. The sex after that was so awesome. She moaned with every stroke. She climaxed in 3 minutes, leaving me to finish jacking off in her mouth after that.
