Fox McCloud was in the kitchen making popcorn in the microwave. It was almost nine o'clock, and he was expecting a movie on the pay-per-view channel to start soon. His wife, Krystal McCloud, had already gotten the TV all set up, and was currently waiting on the couch in the other room with their nephew Miles Tails Prower.
"Hey Fox, the movie is about to start!" the vixen shouted, her voice barely audible over the popping of the microwave. "You almost done in there?"
"Just another minute and it'll be done." Fox replied as he was waiting near the microwave.
In the living room Krystal and Tails were having talking to each other and making sure Fox couldn't hear their conversation.
"Are you crazy, my husband will be sitting next to us and you want me to give you a blowjob when the movie starts?" Krystal asked her nephew who is being daring.
"Oh relax, we'll have the cover over our bodies." He said.
"That's still gonna look conspicuous Tails! Okay, us fucking in the same bed while my husband is sleep right next to us is one thing. But this...this is risky!" Krystal said in a loud whisper.
"Well, the cover is long enough to where Fox can't see us. Just keep him from trying to pull the blanket over to himself, and we should be fine." Tails said with devious look.
"You are too horny for your own damn good!" She said with annoyed look.
"Oh, don't act like you didn't have any fun last night when we fucked in your bed when your cuckold of a husband was sleeping next to us."
"Shh! Keep your voice down. And yes, I did have a great time." She said with a blush.
"I know." He said.
The microwave finished up just as Tails got off the couch and walked into the kitchen with a blanket in his hand. Krystal quickly grabbed the remote and hit the menu button to go through the channels until she found the pay-per-view movies. She then hit the down arrow on the channel button to scroll down through the list and finally hit the ok button to select the movie that they were going to watch.
"Fox, the movie is starting. Are you ready?" Krystal called out.
"Yeah, I'm ready." He replied.
Tails quickly went back into the living room and laid down on the couch and covered himself  and his aunt with the blanket, leaving only their heads exposed. Fox came back into the living room to see his wife and nephew all bunched up.
"Awww, you guys look so cute like that." Fox says.
"Oh hush up Fox." Krystal said and gave him a playful smack on his arm.
"I'm just saying." Fox said with a smile.
"We know." Krystal said.
"By the way I would just like the say I'm glad you two have been getting along. Its really sweet you two want to spend so much time together." Fox says smiling at them not knowing the truth of their secret affair.
"Thanks Uncle Fox." Tails replied.
"Your welcome."
Fox grabbed the remote and sat down on the other end of the couch. He took a couple of pieces of popcorn and threw them in his mouth and then hit the play button on the remote to start the movie.
"Enjoy the movie." Fox said.
"We will." Tails replied.
Krystal turned to face the TV, and Fox was already getting comfortable by putting his feet up on the coffee table and leaning back. They all sit back and relax watching the action movie on screen.
Tails looked to see his uncle was already getting comfy and decided now would be the perfect time to start things off. He slowly slid his right hand under the blanket and started sliding it up his aunt's leg and up her thigh.
Krystal's eyes widen as she darted her eyes over at Tails. She gave him a look that says, "Noooo, don't you do it!" But of course Tails was thinking with the wrong head and slipped his hand under his aunt's pants under the blanket. She wanted to stop him but at the same time, not. 
Her heart was racing as she took a quick glance at Fox who's sole focus was on the movie. She then looked back over at Tails who was staring straight ahead at the TV and smiling. She was nervous, yet excited at the same time.
She felt his fingers grazing against her pussy through her panties, making her body shiver and her pussy throb. Her nipples hardened as they were poking through her bra and tank top. Her face was flushed and her breathing was getting heavy as her nephew was fingering her through her underwear.
"What the hell is wrong with me? Why am I letting this happen? Why am I such a slut for my nephew's cock? God, can I even call myself a good wife anymore?" Krystal was asking herself all these questions while Tails kept pleasuring her.
As Fox reached down to get some more popcorn he noticed Krystal's face was flushed.
"Are you alright?" Fox asked her, not noticing his nephew was fingering his wife.
"I'm..I'm fine honey." Krystal said as she was trying her best to hide her moans.
"Are you sure, you look a little flushed?" Fox asked her.
"I'm...fine, don't worry about me!" She said with a reassuring smile.
"Okay? If you say so? Do you want some popcorn?" He asked.
"I'll take some." She replied.
Fox grabbed the bowl and put it on his lap, and held it up in Krystal's direction. She reached into the bowl and pulled out a few pieces and tossed them in her mouth.
"What about you kiddo, you want some?" Fox asked Tails.
"I'm good Uncle Fox." Tails replied not even looking over at him.
"You sure?"
"Yup, I'm fine. Thanks anyways." He replied.
"Okay, just asking." Fox turned his attention back to the movie in front of him.
Tails looked over at his aunt and gave her a sly grin as he pushed her panties aside and slid two fingers into her dripping wet pussy.
"Ahh!" Krystal moaned out.
"Did you say something sweetie?" Fox asked her.
"Umm, no honey. Nothing."
"You sure? You kinda sounded like you moaned a little." Fox said.
"No sorry, I was surprised what happened on screen!" She said coming up with a lie. She turn towards Tails with a angry look.
"Bitch, you know you love this!" Tails whispered in her ear.
He started rubbing her clit with his thumb, making her squirm and her breathing heavier. She tried not to make any noise and tried to watch the movie, but she was finding it difficult as her nephew was doing wonderful things to her pussy.
Krystal turned and looked over at her nephew and could tell he was hard as he had a bulge showing in his pants.
"If only he knew what his precious nephew was doing to his wife, what would he think of his little nephew?" Krystal thought to herself.
She turned to look back at the TV and saw Fox was completely enthralled in the movie. She was glad her husband wasn't noticing her flushed face and was so oblivious to what was happening. All of a sudden Fox gets a phone call from his friend Falco.
"Excuse me, I'll be right back, don't pause the movie keep watching." Fox says as he gets up from the couch and walks into another room.
Fox goes into the next room to talk to his friend while Krystal and Tails were left alone.
"You naughty bitch, you are enjoying this, aren't you?" Tails teased.
"You're an asshole!" She replied.
"But you love this, don't you? You love having a young fox fingering your tight, wet cunt, don't you?" Tails teased, using a dirty word to describe her womanhood.
"I hate you sometimes..." She said exasperated as she pulled down his shorts and his huge fox cock is free.
She grabs his cock and starts stroking it and he shoves his fingers deeper into her pussy. She starts moaning and leans in closer and starts sucking on his cock, taking his dick inch by inch into her warm, moist mouth. 
Tails tilts his head back just enjoying his aunt's mouth. He can feels her mouth coat his cock with her spit and her tongue sliding up and down his shaft. The living room was filled with the slurping and suction noises. As well as Tails moans as he enjoys himself as the older vixen goes down on him.
"Fuck, your mouth feels amazing." Tails tells her.
Krystal was bobbing her head up and down as fast as she could, wanting to please her nephew. She can feel his cock getting harder and bigger and could tell he was going to blow soon. They hear voice Fox's voice coming closer and closer to the living room. They can tell he was still on the phone.
"Looks like he's coming back, you better hurry up auntie before he catches you." Tails said with a sly voice not caring if Fox catches them or not.
She pulls off his cock and tries her best to tuck it away in his shorts, but can't since it's hard as rock and leaking pre-cum.
"Your not done!" Tails said with a devious smile. "I'll happily let him see my package in it's full glory unless you finish your job."
Krystal hears her husband approaching the living room more. She panics and realize there's only thing to do. 
"Alright man, I'll talk to you later." Fox came back into the living room and hung up his phone and sees Krystal laying on the couch and resting her head on Tails' lap but her body was covered head to toe by the blankets.
"Is she asleep?" He asked.
"Yep, she was tired after we watching the movie, so she kind of fell asleep on my lap." Tails was squirming in his seat as  Krystal was licking the tip of his dick under the blanket.
Fox begins to shake his wife to wake her up. "Krystal...wake up, if your tired go to bed." 
Krystal sits up from the couch pretending to be very sleepy. "Huh...wha..."
"Krystal go to bed if your tired." Fox says
"Yeah..." She stretches and gets up from the couch. "Alright dear, I'll go to bed." She kisses her husband good night.
"Good night, Uncle" Tails said walking pass Fox.
Fox then licked and smacked his lips, tasting a salt flavor on his tongue. "That's weird, did I put too much salt in the popcorn?" He asked himself looking at the popcorn bowl not realizing the salty flavor was the taste of his nephew's sperm.
He eats more popcorn and shrugs feeling it was all in head as he goes back and watches the movie. Krystal and Tails were heading up the stairs.
"Come on, let's get back to my room." Krystal whispers and pulls him up the stairs.
They get to the top of the stairs and make their way towards her bedroom. Tails was walking behind his aunt admiring her ass as her pants were a little tight and he could see her thong outline. He was really turned on and couldn't wait to get into the bedroom.
As they finally went inside the master bedroom, Krystal shut the door. 
"You gotta admit, that was really hot, you blowing me while Uncle fox wasn't even 5 feet away?" He smirks at her.
"Yes, yes it was, and I'm soaking wet because of it. But I'm also really angry." She says.
"Angry? Why are you angry?" He asked confused.
"You're lucky he didn't notice the obvious bulge in your pants, and he didn't notice anything weird. I was afraid he was going to catch us." She said with a serious tone.
"Honestly who cares if it catches, I would love him to watch me fuck you as you keep screaming my over and over." Tails said with a predatory smile as he gropes her ass.
"You're sick, you know that? You're just a horny pervert." Krystal tells him.
"Yes I am, and what does that make you auntie?" He continues to have that shit eating grin on his face.
"Just shut up, and fuck me." She demands and pulls him into a deep kiss as they fall onto the bed.
Tails reaches down and pulls down her pants and underwear and lifts her shirt and bra up. He pulls her in close to his chest and wraps his arms around her waist, while Krystal wrapped her legs around his waist.
"Are you ready?" He asks.
"I've been ready for the last hour and a half." She replies.
Tails slowly pushes his dick inside his aunt's wet pussy, stretching her out and filling her up.
"AH YES! I've been waiting all night to feel this dick inside of me." She moans.
"Oh, your such a whore for my cock." He moans.
"Yes I am, yes I am, now start moving damnit!"
"Alright, alright, jeez, you're so needy." He said grinning, Tails slowly starts to move his hips.
"Yes...yes...fuck, this feels so good!" She moans.
The fox duo was getting into a steady rhythm, they were both enjoying the moment as Krystal had her eyes closed and was loving the feel of her nephew's big fat cock fucking her.
Meanwhile Fox McCloud was in the living room, still invested in the film on the screen. He was sitting on the couch, enjoying his evening snack. He was so engrossed with the film he didn't notice the sounds of bedsprings squeaking in rhythm in the room above him.
"Oh God! Ahh yes, that's it! Yes, just like that. Mmm, that feels so good, baby." Krystal moaned out loudly.
"Yeah, you like that?" Tails asks.
"Fuck yes, I love it. Your so big and filling, and I love it when your balls slap my ass."
Tails grabs ahold of his aunt's hips and starts pounding her harder, making her tits bounce wildly. He was fucking her in the doggystyle position. He leans forward and kisses her neck.
"Heh, you know you were so worry about your husband hearing you before. Now here you are screaming my name, I'm sure he can hear us?" Tails said smirking.
"Who the fuck cares? My husband has no clue about what's happening in this house, and I don't give a shit if he knows or not. Right now all I care about is you and this big fucking cock in my tight cunt." Krystal tells him.
"That's good to know, and I'm glad." Tails keeps moving his hips, his cock keeps hitting her cervix.
"Ahh yes, keep doing that! Fuck yes!" Krystal moans.
Tails grabs her tail and gives it a few squeezes, sending shivers down her spine. Her eyes shoot open as her tail is her sensitive spot, and he is abusing that.
"FUCK! I'm gonna cum!" She screams.
"Not yet." He says.
He flips her over and she's now lying on her back. He gets on his knees and starts to rub her clit.
"Tails please, I'm so close. Just let me cum!" She begged.
"Fine, cum on my cock." He says.
Tails thrusts back into her and fucks her hard and fast, making her scream and moan as he brings her closer and closer to the edge.
"Ohhh, yessss! AHHH!" Krystal's walls clamp down and her eyes roll back into her head.
"Fuck, I'm gonna cum!" He said.
"Fucking do it. Shoot your hot cum in me, make me your slut."
He shoots his load and fills his aunt up with his seed, making her moan and her eyes widen. She loved the feel of his cum filling her up.
"Fuuuuck, yes!" Tails moans as he shoots the last few ropes into her.
Tails then falls forward onto his aunt and she wraps her arms around his neck and they hold each other.
"Fuck....that was amazing...as usual..." She said catching her breath with a satisfying smile on her face.
"So....you think he heard us?" Tails asked Krystal.
"Oh, I don't think so. Fox is still downstairs watching that movie and didn't even bother to check on us. And he has no idea I was screaming his nephew's name." She says.
The two of them lie there together, basking in the afterglow of their love making. They were both completely spent and satisfied.
"God, I'm so happy I decided to fuck you." Krystal told Tails.
"Me too." Tails says.
They share one last kiss before they decided to get up and get dress. 
"Glad to know your getting alot more daring as of late." Tails said with a smirk.
"Well, you tend to bring that out in me." She replied with a seductive smile.
The two of them got dressed and decided it was best if they didn't stay in the same room. Tails went into guest room he was staying in while Krystal opened up a window sprayed some air fresher to get rid of the smell of sex in the air.
**Meanwhile**
After Fox was done watching the movie and finished up his popcorn he went to check on his wife who was sleeping in their bed. He went into their bedroom and saw Krystal sleeping peacefully.
"Aww, my little vixen, sleeping soundly." He thought to himself.
Fox walks over and leans down and gives her a kiss on the forehead.
"I'm so lucky to have you!" Fox says to himself.
"Mmm..." She mumbles.
Fox smiled at his wife. He decides to call it a night and heads to bed.
"I'm glad Krystal and Tails get along, but sometimes I think they spend too much time together." He thinks to himself while putting on his pajamas.
"Oh well, I'm just glad they're having a great time, and hopefully tomorrow we'll do something as a family." Fox says to himself and climbs into bed next to his wife and drifts off to sleep.
