The dark-haired girl voluntarily agreed to the experiment and became a sex slave. Going out into the street, they put a collar on the appetizing brunette and, having tied her hands, forced her to crawl among people, passionately spanking her big ass with a whip. Then, the gorgeous beauty was naked and she walked down the street with a gag in her mouth, showing everyone her big tits and elastic ass, getting true satisfaction from these actions.
