Smiling, Mark nods.

“That’s good, because Ilike watching you fuck her,” Nikki says. “But I can’t help butthink we’re still being too easy on her.”

“I agree,” Marksays.

“What do you think?” Nikkisays. “Should you stick your cock in her tight littleasshole?”

Mark nods vigorously.

“Yeah?” Nikki says. “Doyou want to fuck her ass?”

“Very much so,” Markssays.

“I’d ask Cindy if that’sokay with her,” Nikki says. “But it doesn’t really matter, does it?Because we’re going to do it anyway. But first, we need to get itready.”

Keeping her pussy on top of Cindy’s head,Nikki leans down further, takes one of Cindy’s asscheeks in eachhand, and opens them up, exposing her tight little asshole.

“You hold these open,”Nikki says to Mark. “I’ll get her warmed up.”

Mark takes over, spreading Cindy’s asscheekswith his hands while Nikki sticks the middle finger of her righthand into her mouth. Once it’s good and lubed up with her saliva,Nikki slides her middle finger into Cindy’s asshole.

Cindy lets out a little shriek.

“Again, I don’t care,”Nikki says while working her finger into Cindy’s asshole while Markcontinues fucking her pussy. “If you play with the bull you get thehorns. Next time maybe you’ll think about what you’re doing beforeyou play with another woman’s husband. Now shut your mouth and takeit.”

After Nikki loosens up Cindy’s asshole withone finger, she lets a trail of saliva drop out of her mouth andinto the crack of Cindy’s ass and watches it run down the edge ofher ass and into her anus. Nikki uses this extra spit to slip herindex finger into Cindys asshole, making it two total.

Cindy doesn’t shriek this time, instead hermoan reveals more than a hint of pleasure.

“Oh,” Nikki says to Mark.“I think she likes it.”

“Then I guess it’s timefor my cock,” Mark says.

“My thoughtsexactly.”

Nikki pulls her fingers out of Cindy’sasshole and grabs ahold of the base of Mark’s cock. She pulls therest of his cock out of Cindy’s pussy, then nestles it up againstCindy’s asshole, which is gaping and ready to accept it.

Mark pushes his hips forward and lets out alow groan as his cock slides into Cindy’s asshole. Cindy takes in asharp breath and lets out a high-pitched moaning whine. But Markpays no heed, continuing to push ahead, forcing his cock deeper anddeeper into Cindy’s asshole, one inch at a time while Cindy squirmsmoans beneath him.

“There you go,” Nikkisays, her smile wider than ever. “Give her the whole fucking thing.Don’t stop until your cock has disappeared inside her.”

Mark’s hands have migrated to Cindy’s hipsfor leverage and Nikki replaces them with her own, holding Cindy’sasscheeks open, giving her a clear view of her husbands cockdisappearing inside Cindy’s asshole.

“That’s what I’m talkingabout,” Nikki says once Mark is balls deep inside of Cindy. “Nowpummel her fucking asshole like there’s no tomorrow.”

So Mark does, pulling his hips back beforepushing them forward, fucking Cindy’s asshole with his entire cockwith every thrust. He takes it slowly at first, getting her niceand loose, but it isn’t long before he’s hammering his cock in andout of her, his balls slapping up against her pussy while his cockslams in and out of her asshole.

“Holy shit that’s sofucking hot,” Nikki says. Her head is lying on top of Cindy’s ass,her face mere inches from the younger girls asshole. Nikki looks upat Mark with gleaming eyes. “She takes that cock good in her ass,doesn’t she?”

Mark nods.

“Yeah,” Nikki says.“Something tells me that she’s been fucked in the ass a few timesbefore.”

While Mark continues pummeling Cindy’s ass,Nikki climbs off her head so she’s sitting on the floor in front ofthe younger girls face.

Nikki grabs ahold of Cindy’s hair and liftsher head until they are face to face. Looking deep into the youngergirl’s eyes, speaking only loud enough that she can hear, Nikkisays, “Have you learned your lesson yet?”

Cindy nods. She’s biting down on her bottomlip and a grunt escapes from her throat every time Mark slams hisbody into hers. From the look on her face she appears to be indistress but her eyes tell a different story. They are positivelygleaming. She is enjoying this.

“But you like it too,don’t you?” Nikki says. “You like getting dominated and fucked byrelative strangers, don’t you?”

Cindy nods again.

“Yeah, I can tell,” Nikkisays, still holding Cindy’s head up by her hair. Her tone ismeasured, calm, as though they were having a regular conversationthat didn’t include one of them getting fucked in the ass as theytalked. “I can see it in your eyes.”

Mark lets out a low moan and starts to speedup, fucking Cindy even more aggressively, hammering her so hardthat her body is pitching forward every time he slams into her.

Nikki looks up at Mark and smiles, thenreturns her eyes to Cindy. “Well, fortunately for you—orunfortunately, depending on how you look at it—Mark is just aboutdone. Isn’t that right, Mark?”

Mark just nods. From the look of pure intenton his face he couldn’t talk even if he wanted to.

“Which means,” Nikkicontinues, returning her gaze to Cindy. “We are almost done heretoday. But if you truly enjoyed yourself as much as I think youdid, there’s no reason why today can’t be the only time we dosomething like this.”

Cindy opens her mouth to speak but Nikkiclamps it shut.

“No need to say anythingnow,” Nikki says, her tone still as calm and measured as earlier.“Just go home when we’re finished here and decide what you want todo. No hurry. And if you decide you want to continue along thispath we’ve started here today, then come on over sometime and we’llpick up right where we left off. And next time we’ll start to getreal filthy.”

From above them, Mark mutters “shit, shit,shit,” under his breath.

“Well, that’s his cue,”Nikki says. “Just a few more seconds now. But remember what I said.We’re game for more of this if you are. Anytime. Just come on over.Okay?”

Cindy nods between grimaces as Mark slamshis cock into her asshole harder than he has all night. Nikkiflashes her a smile and gives her a playful little smack on thecheek, then turns her attention up to Mark.

“Are you ready?” Nikkiasks.

Mark nods vigorously.

“Then let her have it,”Nikki says.

Mark pumps his hips a couple more times,then groans “holy fuck,” and yanks his cock out of Cindy’s assholeand jerks himself to completion, shooting stream after stream ofcum all over Cindy’s back.

Nikki laughs softly and shakes her head inamazement. “That was pretty impressive,” she says to a smilingMark. “I think you even got some in her hair.”

Mark laughs goofily while Cindy remains inthe doggy position, her back arched and her ass sticking up in theair. Her back is painted white with Mark’s cum and her chest isheaving but there is a huge smile on her face.

“That’s a good girl,”Nikki says, matching her smile. She leans forward and slips hertongue into Cindy’s mouth. They make out while Mark stands overthem, watching and smiling.

After a few seconds, Nikki breaks off thekiss, then stands up and helps Cindy to her feet. “Now you getcleaned up and get yourself home,” Nikki says. “And maybe we’ll seeyou again soon.”

Ten minutes later, Nikki closes the frontdoor behind Cindy then heads into the kitchen. Mark is sitting atthe dining room table, drinking a soda and staring through thewindow at Cindy as she makes her way across the lawn and down thesidewalk, towards her house.

The younger girl has a spring in her stepthat has her practically bouncing. She looks back at the house,smiling, and gives a little wave. Nikki waves back then sits downacross from Mark.

“Well, that seemed to gowell,” Mark says.

“Yeah, even better than Ithought it would,” Nikki says.
