In Nikki Darling: Training Day Four, Nikki is still trying to untangle and coil up all the heavy rope in the basement. It has been four days under the stairs in the nastiest part of the basement with this rope task. It smells, it is cold, and she is slow. This is her last chance to finish before she is severely punished. Her final routine is a dance on the tip of a hard cock. In sexual training, they strive for the slave to do the work. A slave girl should be bouncing all over that hard cock and loving it, so they make her present her nice ass and let the gimp pump her until it cums all over her! Cast: Nikki Darling, Others
