Perverted Toilet Filling With Two Dirty Arses

Yara and Claire sit on the bed on which Cosmo is tightly secured. The two ask him if he likes shit, to which he replies in the affirmative. Today is going to be really dirty.
Lady Claire sits down on his face and has her bumhole licked with relish. Miss Yara also wants to moisten her dirty hole a little.
Then Claire sits down on the slave's chest and spreads her legs upwards. Seeking eye contact, she shits in Cosmo's mouth. The sausage more than fills his mouth and Cosmo tries to bite off the rest.
But Miss Yara catches him trying to make his bumhole even dirtier instead of cleaning it. She starts to spread the shit all over her rosette and sticks a finger up Lady Claire's bum. She visibly enjoys the treatment.
Then Miss Yara also shits in the slave's mouth. While the slave swallows, the two dominas show off their dirty bums and stimulate the cock until Cosmo experiences a strong orgasm.
