Preparation as a Toilet for Three Mistresses Part 2

Yara makes the rules of today's filling clear. If everything is swallowed, Cosmo is allowed to have an orgasm. If he swallows quickly, he gets anal sex. If he doesn't swallow everything, he gets nothing. Cosmo is also made aware of the importance of his training. The other mistresses should also be able to use him as a toilet. Miss Yara doesn't want to make a fool of herself.
