You can tell you fucked your girlfriend great when her skin turns pink and she almost screams when you make her cum. It took me an hour of restless fucking to satisfy her pussy, 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 dick into her warm tight ass hole. I'll never forget the feeling the first anal penetration gave us and the way her quiet moans of distress turned into loud moans of pleasure.
