为三个女主人准备上厕所 第一部分

Yara explains to Cosmo that he and she will soon be visiting her friend and dominatrix Miss Medea. Lady Claire will probably also be visiting there. Cosmo will therefore be used as a loo by three mistresses for the first time. Miss Yara doesn't want to be ashamed of her slave and therefore starts training him early. Over the next few months, she plans to ensure that the filling works better and better and that the toilet swallows diligently.
