“Gladly,” Mark replies,grabbing ahold of Cindy’s head and holding it in place as hethrusts his hips forward, slipping his cock into hermouth.

Nikki drops to her knees and slips twofingers into Cindy’s shaved, dripping wet pussy. They slide ineasily, with very little resistance.

“You reallydo love this, don’tyou?” Nikki says, laughing under her breath. Sitting perpendicularto Cindy, she works her fingers into Cindy’s pussy without mercy,slamming them in and out as quickly as she can while Mark continuesto fuck Cindy’s face.

“Answer me,” Nikki says,sliding a third finger into Cindy’s pussy.

Cindy mumbles something as best she can withMark’s cock still working in and out of her mouth.

“I can’t hear you,” Nikkisays, slamming her fingers even more aggressively into Cindy’spussy.

“Yes,” Cindy manages tosomehow say even though Marks cock is still in hermouth.

“You can take even more,can’t you?” Nikki asks.

“Yes,” Cindy managesagain.

Nikki slips a fourth finger into her pussy,forcing it in despite the tight fit, and continues bangingaway.

Cindy lets out a deep groan but Mark justtakes the opportunity to jam his cock deeper into her mouth. Heholds it there, deep in Cindy’s throat, while Nikki holds herfingers as far as they’ll go into Cindy’s pussy, also holding themthere.

Cindy shimmies and shakes from thedouble-ended deep penetration but there’s nowhere for her togo.

“Take it,” Nikki says,punctuating the words with another slap to Cindy’s ass. “Take itlike the dirty little slut you are.”

  And take itCindy does, still gagging and moaning behind Mark’s cock but notfighting so hard to get away.

“That’s a good girl,”Nikki says, sliding her fingers out of Cindy’s pussy just as Markslips his cock out of her mouth. “You’re ready for the nextstep.”

As Cindy fights to recover, Nikki grabs herby the hair and spins her around so that her ass is now facingMark. Cindy still hasn’t fully caught her breath when Nikki jamsher fingers into Cindy’s mouth.

“Do you know where thosejust were?” Nikki asks, taunting Cindy. “They were jammed into yourpussy.”

Cindy gags, but whether it’s from thethought of tasting her own pussy or because Nikki has jammed herfingers so deep into her throat that’s causing it. Not that itmatters all that much, because Nikki has her own ideas on thematter.

“Oh, you don’t like that,huh?” Nikki says. “Well too fucking bad, bitch. You brought thisonto yourself. Now lick those fingers clean of your juices while byhusband fucks your pussy from behind.”

Nikki looks up at Mark and nods her head.Mark’s smile widens and he scoots his body forward until he’ssidled up to Cindy. Then he slips his cock into her pussy.

Mark hammers away at Cindy, fucking her frombehind while Nikki continues to hold her fingers in Cindy’sthroat.

“Fuck her good,” Nikkisays. “Pummel that pussy with your fucking cock. Give it to herdeep and hard, just like she likes it.” Nikki slides her fingersout of Cindy’s mouth. “That is how you like it, right?”

Cindy nods.

Nikki gives her a mildly threatening look,tilting her head and narrowing her eyes.

“Yes,” Cindy says betweenmoans of pleasure. “That’s how I like it. Hard anddeep.”

“See?” Nikki says, lookingup at Mark. “Straight from her own mouth. You heard the girl. Giveit to her like you mean it.”

Mark’s grin grows wider and he startspumping his hips harder and faster, his groin slamming up againstCindy’s tight little ass, pushing her body forward every time theycome together.

The sounds of sex fill the room—the wetsmacking of flesh, grunts and groans and moans and heavybreathing.

“There you go,” Nikki saysto Mark. “I always knew you had it in you. It just took a dirtylittle slut to bring it out of you.” She rises up and leans forwardand sticks her tongue into Mark’s mouth and the two of them makeout while Mark continues fucking Cindy from behind.

After breaking off the kiss, Nikki positionsherself so she’s on her knees in front of Cindy. “Are you ready forthe next stage in your punishment?” she asks Cindy.

“Yes,” Cindy answersbetween deep, gasping breaths.

“Very good,” Nikki says.“You answered without even being told this time. You’re progressingnicely.”

“Thank you,” Cindysays.

“Now it’s time for themaster class,” Nikki says, pulling her own shirt and then bra off,revealing perfectly round, incredibly perky tits which areobviously fake but tastefully done. “Are you ready?”

“Yes,” Cindyanswers.

Smiling, Nikki grabs ahold of the back ofCindy’s head with both of her hands, and simultaneously pullsCindy’s head forward while leaning in towards her, smashing Cindy’sface up against Nikki’s flesh, right in between her tits.

With Nikki’s arms wrapped around Cindy’shead, she hold Cindy in place against her, smothering the youngergirl with her flesh while Mark continues hammering away at herpussy from behind.

Ten seconds later Nikki releases Cindy,giving the younger girl a chance to breathe. Nikki allows Cindy twodeep gulps of air before pushing down on the younger girl’sshoulders, forcing her head to the carpet.

“Get your head down,”Nikki says, angling Cindy’s face so half of it is pressed upagainst the carpet before climbing to her feet. “Right there.That’s right. Just like that. Stay right there.”

As Mark continues pummeling Cindyrelentlessly from behind, not letting up at all, Nikki slips hersandals off then puts her foot on Cindy’s head, pressing down onit, keeping flush against the carpet.

“Slap her ass,” Nikki saysto Mark. “Punish that dirty little slut while you fuckher.”

Mark obliges, smacking Cindy’s ass cheekwith an open palm until it’s bright red.

“Okay, I’m sick of beingon the outside looking in,” Nikki says, slipping out of her jeans,revealing a red g-string. “Time to get more involved.”

“Go for it,” Mark says,pausing for a little break but keeping his cock planted deep inCindy pussy. “Show her what it’s like to play with the bigkids.”

“I’m planning on it,”Nikki says, dropping down to her knees with her shins on the floor.She drops her pussy on Cindy’s head and rubs it back and forth. Butthat’s not enough for her.

“Something’s missing,”Nikki says to Mark. “We’re still taking it too easy on her.” Shethinks for a moment, then sees her shirt on the floor. “Aaaahhhh,”she says, reaching over and grabbing the shirt. “I’ve gotit.”

Still sitting atop Cindy’s head, Nikki laysthe shirt across Cindy’s shoulders, then grabs the younger girlsarms and wrenches them backwards until they’re folded behind herback, her wrists crossed over at the small of her back.

Cindy lets out a little yelp.

“Oh, you didn’t likethat?” Nikki says mockingly. “Well too fucking bad. You should havethought about that before you decided to try and fuck my husband.Now shut up and take it.” Nikki turns her attention to Mark. “Holdher arms there,” she says.

Mark does as he’s told, keeping his cockinside Cindy but not moving for the time being.

“Did I tell you to stopfucking her?” Nikki says.

“No,” Mark replies. Ifhe’s bothered by being bossed around like that he makes noindication. In fact, from the little smile perched on his face, itseems like he enjoys it.

“That’s right,” Nikkisays. “I didn’t. So start up again.”

Mark obliges, working his cock in and out ofCindy’s pussy more aggressively than ever while continuing to holdonto her arms.

“That’s better,” Nikkisays. She grabs the shirt and wraps it around Cindy’s wrists in acomplicated pattern, binding them together behind Cindy’s back,incapacitating them.

“There we go,” Nikki says,obviously satisfied. “Now we can get to work on this little slutfor real.”

Riding Cindy’s head once again, Nikki leansforward and starts making out with Mark while he continues fuckingCindy from behind.

“You like fucking thislittle slut, don’t you?” Nikki says after breaking off the kiss.Her face is mere centimeters from Mark’s.
