A naive 45-year-old milf named Sarah — stunning, deep-tanned, with a thick voluptuous body, enormous huge tits, a big plump ass, and long blond hair in a ponytail — is sent by her busty friend Jessica to try “relaxation yoga.” But the instructor Kris runs a discipline called MyPet: obedience disguised as wellness. He reads her in one pose and begins training her into an obedient BDSM pet, while her husband Tom stays blind at home. Chapter by chapter, Sarah’s surrender deepens — from a command to lewd lingerie to her first deep-throat on Kris’s giant veined cock, until she kneels and calls a stranger “master,” wanting more.
