Slapped for having a small dick

Mistress Jade is furious with her slave; not only does he have such a tiny dick that it is useless, but even the sight of her gorgeous body and ass can't make it hard. Jade decides that, if being erotic can't give this loser a boner, then maybe some sadism can. Jade smacks him in the face right when he thinks he is going to get to kiss her ass and doesn't let up from there. She slaps him again and again, even delivering several from a full windup while making the slave count the hits. Jade has found some use for this slave after all.
