Yang instantly took off her clothes and dropped to her hands and knees, big tits swinging, her muscles bulging a bit as she kept her balance on all fours

"Mooo..." She droned.

Duke smiled and gave her a gentle pat on the head.

"Aww. Who's a good cow? Who's a dumb, big tit cow slut?" He said like he was talking to an animal

"Moooooo..." She replied dumbly.

"That's right! You are!"

Glynda cleared her throat

"Ahem. Master, is it truly necessary that I be here for... This?" She asked, gesturing towards Yang.
