You can tell you fucked your girlfriend great when her skin turns pink and she almost screams when you make her jizz. It took me an hour of restless fucking to satisfy her cunt, but I still wanted more and her pink slit just couldn't take it. That's when I started massaging her sphincter and she finally let me ease my hard cock into her warm tight behind hole. I'll never forget the feeling the first anal penetration gave us and the way her quiet moans of pain turned into loud moans of pleasure.
