Mistress Mona Thea strolls into the living room, Her runway-model body, long legs and perfect *ss on display in a super sexy one-piece bikini. She has Her sl*ve positioned, laying backward on a reclining sofa, its wrists chained, a blindfold, and a mobile cam on its chest. She asks the sl*ve, who must have some idea why it's chained there:

"Do you know why I have you there sl*ve? You're going to become My Own personal *ss sl*ve. I've kept your pathetic excuse for a c*ck locked away in chastity, so it probably doesn't matter to you much that all you get is *ss from now on-I mean, it's all you're good enough for"

The sl*ve just says 'yes Mistress' as She straddles its face with Her *ss facing the sl*ve. She looks behind at the sl*ve as She takes a finger and starts rubbing it on Her *sshole sensuously, back and forth. She pushes it deep into Her *sshole, all the way up to the second knuckle, and wiggles it around deep inside. She slowly pulls the now-glistening finger out and holds it up to the sl*ve's nose, rubbing it above its upper lip. She tells the sl*ve:

"Take a deeep sn*ff now, b*tch. Tell Me, what does that smell like to you? Does it smell good?

The sl*ve gags slightly, but quickly recovers and mutters:

"Your *sshole, Mistress"

She suddenly reaches around and viciously slaps the sl*ve across the face with the hand with the soiled finger. She rubs it over the sl*ve's lips, asking it:

"...and what did I tell you the name of My perfect *sshole was? How DARE you disrespect Her like that!"

"Mistress Julie, Mistress"

"That's better, now tell Mistress Julie how good She smells and how much you're looking forward to your date with Her tonight. I want you to speak to Mistress Julie and NOT ME"

The sl*ve does, while She digs Her finger back inside Her *sshole, pulling it back out She tells the sl*ve to stick out its tongue. She wipes the soiled finger on the sl*ve's tongue and makes it suck it clean, digging HEr finger back inside She does this a few times then makes the sl*ve thank Mistress Julie for allowing it to taste Her. She orders the sl*ve to stick its tongue out again. She grabs both *ss cheeks and spreads Her luscious *ss wide open, revealing Her puckered starfish. She lowers Her open *sshole onto the sl*ve's tongue, ordering it to keep its tongue stiff:

"Make your tongue into a l*ttle c*ck, or a butt-plug. That's all you are to me, sl*ve. Just a piece of human toilet paper, a butt plug, an *nema or a toilet. You're just there for My *ss and everything from it. Now explore the insides, I don't feel that tongue where it belongs"

She keeps Her asscheeks spread wide and starts to face f*ck the sl*ve's tongue with Her *sshole, bouncing up and down, faster and faster until She gets a rhythm and squishing sounds are coming from the sl*ve's wet tongue scrubbing the insides of Her sphincter. She takes rests intermittently, sitting on the sl*ve's face with Her full weight, Her *ss cheeks bulging on either side of its facial cheeks. A perfect match it would seem. She gets off the sl*ve tongue, it gasps for air as She stays on it longer and longer. She then reverses direction and faces the other way. She gets even more aggressive, now cropping the sl*ve's body, leaving red welts:

"Sl*ve, your paws are right there and you don't even try to assist your Owner. Spread My perfect *ss cheeks you f*cking st*pid pig and get your f*cking tongue into My f*cking intestines! I want you to be able to tell Me what I ate for dinner"

She face f*cks the sl*ve with Her *ss again, bouncing up and down on the sl*ve's ever-extended tongue. She starts to obviously enjoy it more and more, giggling in between l*ttle gasps of pleasure.

"Deeper you f*cking piece of trash! You're just like a f*cking toilet brush for My *sshole, scrubbing the insides clean. Now swallow, and flush your toilet mouth for more cleaning"

She sm*ther the sl*ve for longer times, constantly demanding it get its tongue deeper and whipping its body more often and harder, then sm*shing its face under Her *ss telling it to:

"PROBE-WIGGLE IT AROUND INSIDE.....Mmmmm" She finally rises up to give it a few breaths, then back down onto the tongue, demanding it go deeper. Finally, She seems satisfied and rolls off the sl*ve's face. She starts laughing at the sl*ve and pointing at it's now shiny, and no doubt ripe smelling face:

"Hahah, your f*cking face looks just like a glazed donut...but from My *sshole"
