Donna reclaims power, crueller than ever

Donna glares at Erin with something akin to love and caring in her eyes. Then, as if she suddenly realizes her own fragility, shakes it out of her head and here eyes turn cruel. She peers at Erin.

And you start to wonder what Donna is capable of. You realize you're not entirely certain.

She caresses Erin's cheek. "Did you like that dear? Did you like licking up cum after it had been in someone's tummy first?"

Erin smiles a bit. She seems to be responding to the softness in Donna's voice. You wonder if she's not noticed the cruelty in Donna's eyes. "Yes" Erin answers proudly.

"THEN DO IT AGAIN" Donna's eyes go wild, and her and immediately thrusts itself into Erin's mouth and down her throat.

Poor Erin never sees it coming. Her sweaty nude body retches and gags. She tries to resist, then realizes the pointlessness of it. And soon the cum has returned, erupting from out of her lips, past Donna's hand, down Erin's body, onto the floor.

Donna pulls her cum covered hand from Erin's throat and wipes it in your girlfriend's hair. "I said clean up this mess you fuck pig!" Donna shouts.

And watching this girl who you've dominated so many times herself dominate your girlfriend to degrees you never thought she had in her, makes you too impossibly horny. As you and Donna look down at Erin, who is again on her hands and knees, licking the gooey cum off the floor, you decide to act.

You unbutton your pants and pull them down. Your hard thick cock pops out easily. And you sneak up behind Donna, until she feels your erect member on the flesh of her ass. You wrap one hand around her neck, and the other around her chest, squeezing her tit, feeling it wet and gross, covered by the remnants of the cum she'd eaten and Erin's saliva as she licked it off.

Donna doesn't even look back at you. She closes her eyes and moans, and immediately prepares herself for you, reaching her slick, cum covered hand, the one that had just been down Erin's throat, back behind her and into her asscrack. She's lubing herself up for you.

Meanwhile Erin doesn't notice what's happening at all. She's too busy licking cum off the floor, and then attempting to gather it off her body with her petite little hands, nails still painted from this morning, when she was almost a different person, a girl who thought she was subservient, but had no idea what true servitude was, and then licking that cum from her hands.

You slide your cock into Donna's thin ass.

Donna's voice quiver. "Oh fuck yes" as you begin to thrust into her.

Erin looks up.

"Look at me you fucking cunt. Do you see what's happening? Do you see how your boyfriend is rewarding me for mistreating you?"

Erin's face looks like it's never looked before. Her eyes are sad, her teeth are clenched in either anger or impossible arousal, her breast heave with excitement. Her lovely breasts with their pierced nipples. She thought she was the naughtiest girl on the planet the day she did that for you.

Now she watches as your cock is buried deep inside Donna's ass, as your flesh slaps against hers.

"Yes Master! Yes Master!" Donna whimpers. She can change from wild dominant to meek submissive and back to dominant amazingly quickly. She peers back at Erin "See how I've earned... oh fuck yes... his cock deep inside me. You may never get this again. Not until you become a better fuck pig. Understand?"

"Yes." Erin nods quietly.

"You're an inferior fucking cunt aren't you?" Donna talks through her teeth. She's so wild with lust now as your cock thrusts harder and harder into her ass.

"Yes" Erin nods.

"You may think you're reaching your full potential. But that's because you have no idea what your full potential is." Donna barks as you slide your hand from her tit, down her spit covered thin body, and curl a couple fingers into her soaking wet twat. "Fuck yes! look at how your man treats me."

Erin just watches and bites her lips.

"Doesn't it make you want to finger yourself?" Donna asks.

Erin blinks at her surprised. "But you haven't ordered me to..."

"A good fucking fuck pig knows when she's required to rub herself off. An inferior cunt makes excuses."

And almost immediately, Erin's hand makes its way to her own wet pussy, thrusting several fingers inside, as if there's no point starting off gentle, and instead just abusing the fuck out of her own cunt. She winces. Her mouth drops. She fingerfucks herself hard.

Donna continues "And you haven't even... fuck me!... finished cleaning up your mess."

Erin looks around, as best she can with her eyes rolling back in her own head. She sees no mess. Neither do you. "Where Miss?" Erin asks, clearly terrified that she really has missed something.

"Over there..." Donna pants. "All over the front window."

Erin looks over. The front window is clean. "I don't see any..." then she suddenly realizes what Donna wants. "...yes Miss."

"Yes what?"

"Yes, I've missed the mess."

"Why?"

"Because I'm an inferior cunt."

"Now go fucking fix that. Go fix that while your man fucks my ass." Donna is in nirvana. You give her cheek a smack. A reward for a job well done.

Erin crawls over to the front window. The curtains are open. Anyone on the street can see her. And she goes to work, taking the fingers that were just inside her pussy and shoving them down her throat. And once again the cum she's drank erupts from her lips, this time exploding all over the front window.

You lean in close to Donna's ear. "You are cruel."

"I'm honest, Sir" Donna answers.

"Wouldn't you be hurt if I told you that you were inferior?" You thrust into her particularly hard

"I know what I am Sir. I know that my place is on the end of your cock. I know that until I can spend 24 hours a day being a fuck pig, I've not reached my full potential. But my purpose in life is to try."

"And what are you doing to my little girlfriend over there?" You both look over at Erin who is now licking the cum off the glass window, her whole body pressed up against it for the neighborhood to see. She licks at it excitedly and eagerly, clearly wanting to please Donna.

"I'm showing her the joy of having a purpose." Donna grinds her ass back into you. Her whole body is filled with excitement. She always loves taking it in the ass.

"And when does it end?" You thrust and thrust.

"When you say it does Master."

"And what if I say it never ends? What if I tell you to quit your job and quit your life and spend the rest of your time training my girlfriend to be a bigger fuck pig than you will ever be? What would you say to that?"

"Yes sir. Always yes sir. My life is yes sir."

And with that, you can't hold back any more. "Fuck I'm cumming" you say. And just as she always does, Donna pulls her body off your cock, spins around, drops to her hands and knees and shoves your cock into her mouth. Your cum pours down her throat. And she swallows it all. She loves swallowing cum.

When she turns she sees Erin, next to her on all fours, looking at her with submissive puppy dog eyes. Looking for some encouragement, or maybe a little bit of sharing.

"What you want some of your boyfriend's cum?" Donna asks impetuously before spitting at Erin, mostly saliva onto her exhausted face. "Fuck that! From now on you earn it. And there's still cleaning to be done, understand?"

"Yes Miss."
