Wow! That looks painful, but she loves it. She jams herself all the way down on his cock to make sure the nails hit her, and she moans with pleasure every time they do. Fantastic!
She loves his tiny cock, the fact he can barely orgasm, and his useless balls because he's devoted to her completely. She's had all the huge cocks already, uh huh. But his destroyed little cock in that cock ring with nails...THAT makes her cum. Power, not the phony kind either, is intoxicating.
