Mistress Masha considers facesitting an essential part of the slave's education. She's being helped by her very youthful female slave. The Mistress strangles her slave with her wonderful ass and makes him worship her ass, she controls his breathing, she makes his tongue penetrate her anus deeper. Also the Mistress orders her male and her female slaves to lick her anus and her pussy simultaneously and she's getting double pleasure of that.
