Riding a big black dick is just my life as a submissive whore. My master will deny me any sexual release for weeks then shows up with this guy. I have to climb on his dick using only my spit for lube. This massive dick is so thick and long I feel my pussy walls screaming to release the stretch. That is until I finally cum. That sweet juicy lube making his cock slide in easier and it looks great dripping down his chocolate balls. He flips me onto all fours and drives his dick even deeper than before. My cunt feels like it is ripping apart. With a hard smack to my ass he finally lets his cum flow all over my backside.
