One of my favorite positions, aside from face fucking, is when Ryan fucks me "reverse cowboy." It's a nice pain and it feels so damn good. When his dick gets rock solid, he gets on top with his ass/balls facing me. He slides his cock in and it rubs along my back pussy walls. It's a good pain, always on the verge of using my safe word, pressing down deep, to the rear, and rubbing hard behind my ass hole. Despite, the intense pleasure it gives me, every single time we do this position, Ryan ends up in the needing a visit to the doctor. And because of the problems it causes in Ryan's urethra and prostate (the intense bending backwards and hard sex causes the urethra and prostate to get inflamed, and sometimes infected --- not good), we may never "reverses cowboy" again. It makes me so, so sad.
