Nothing gives Mistresses more pleasure than having a slave who is attentive to their every need. A slave who understands that Mistresses desire cleanliness and tidiness at all times.

Even while smoking.

So it should come as no surprise to their slave that when they smoke they require him to be the smoke vent for all their smoke so that it doesn't escape into the Dungeon.

They also abhor ash or littering with cigarette butts so the slave is expected to clean all that mess up with his only available resource - his mouth!
