Tails the fox was riding in the car with his mom. "Ugh, mom do I have to go and spend time with Uncle Fox?" Tails asked his mother. "Why not dear, you use to look up to your Uncle, and listen to all his space adventures?" She said.

"Yeah, but that was when I was little, besides he's probably just gonna bore me with stuff  and I already been on plenty of adventures myself with Sonic." He replied. "Come on, sweetie you haven't seen your Uncle in...actually I don't know how long?" His mother pounder. "But you are willing to hangout with your cousin Marcus!" She points out.

"That's because Marcus is actually fun to hang around. Besides Marcus is not even going to be at home all summer. He's gonna be at Space camp to be like his dad." Tails said annoyed.
They finally pulled up at the McCloud residence. "Just try to have fun, okay? And be your best behavior!" She says to him but Tails rolls his eyes. "Fine mom..." He then looked at her and gave her a sly smile. "Hey mom, wanna give me a goodbye blow job?" He asks his mom.

His mother was not happy about this. "Tails! No! We talked about this and no more sexual things between us, it's wrong and I am married to your father!" She said. Tails rolled his eyes at her feeling annoyed. "Whatever, I know you missed tasting my dick." Tails said with a attitude in his voice as he grabs his things and leaves the car.
Tails left the car without saying goodbye to his mother.  He sees the big house that Fox McCloud owns with his aunt Krystal. Who is a retired space marine.

He then goes to the front door and rings the doorbell. The door was opened by a blue vixen with a nice slim body and green eyes. Tails couldn't help but get hard looking at his Aunt Krystal.
"Damn..." He said under his breath as he admires his aunt's sexy body. She had curves in all the right places. Her breasts were medium size. Tails had a hard time taking his eyes off them.

"Hey what's shakin, babe?" He said greeting his aunt in a flirtatious manner. Krystal was taken aback by this because even though it's been years since she last seen her nephew. She didn't expect their encounter to be like this!
His uncles then came behind his wife to greet his nephew. "Miles! Long time no see, man how have you grown." Fox said. 

"Yep it's been a while!" Tails responded.

"Look, I'm glad your here. I'm sorry your aunt and I miss some parts of your while you were growing up. Being a space marine is a lot of work for the both us." Fox explains.

"Nah, I get it. Being a hero can take up a lot of time." Tails said with a cocky tone, but he can relate.

"Well, I'm glad you understand. It's a shame Marcus can't be here with us. I'm sure you guys would've love to hang right now. But anyways come in." Fox said, and Tails walked in said the house, getting a good look at Krystal ass while he follows them inside.

They were all sitting at the kitchen table having a causal conversation about life. Tails' gaze mostly focus on his aunt, and his uncle didn't really seem to notice while they were talking. Then Krystal took her husband in another room for a private discussion.

He can hear the muffled angry voices of his aunt and uncle arguing in another room. He can't tell what they are talking about but honestly he doesn't really care anyways.

While Tails was alone in the room, he sees Krystal's phone on the table. The fox boy smirked and grabbed her phone. Luckily she didn't have a passcode on it. That was weird but hey it made things easier.
Tails goes through her phone and find several videos of Krystal and her son Marcus engaging in sexual intercourse with each other.

"Damn, my cousins and aunt are a bunch of perverts, huh? They must've been banging each other for years!" Tails thought.

"What should I do now? Should I keep this a secret and jerk off to it?" Tails asked himself. But he then had another idea in mind. He texted the videos to himself and saved them on his phone. 

"Oh Blackmail, I love you!" The two tail fox smiled evilly.

When his aunt and uncle came back, they sat down with their nephew again. "So Miles, how has life been going?" Krystal asked trying to be polite to him.

"Please, just called me Tails. It's what I prefer anyways." He states.

"Really? I thought you always hated that name, because mean kids use to pick on you and call you that." Fox said.

"Yeah, I took the name as my own. I surprised you never knew about that. Considering how famous I am as a sidekick." Tails being cocky.

"Oh...well, um, anyway how's the family life going for you, Tails?" Krystal asked again.

"Mom and dad are great. Dad still has his job at the university, and Mom is still a nurse." Tails answer.
"Are you dating any nice girls?" Krystal asked.

"No, not exactly. But you could say someone has caught my eye." Tails said smirking and Krystal knew he was referring to her.

"Well then bud, don't waste the opportunity if you see something you like, go for it and take it!" His uncles says being encouraging.

"Oh....intent too!" Tails said.

"Welp, I still got work to do at my office, I don't mean to be rude but hon, why don't you show Tails to the guest room." Fox told his wife as he left the room and went to his office.

As soon as they heard the door shut to his office, Krystal took off her nice aunt persona in front of Tails. "Okay, let's get something straight! Listen I am flattered by your attempts at flirting but I am a married woman, and you will respect that!." The blue vixen said sternly.

Tails rolled his eyes at her. "You will respect me in my home!" As Krystal talks Tails is not really listening. All the things she is saying is going in one ear and out the other. The fox boy was just really focused on her cleavage while she talks.

"I mean really! I know I haven't been around, but I have known you since you were a baby, and-" 
"So...when did you start fucking your son?" Tails asked cutting her off with a smug look on his face.

Krystal heart drops to her stomach, her eyes go wide when she heard that question.
"W-what?!" Krystal asked in a shaky voice.

"Yeah, I have your sexy nudes all over your phone, and also those naughty videos of you and Marcus, doing the nasty!" Tails said holding his phone.

The blue vixen was panicking as she takes Tails' arm and rushes him into the guest bedroom where they could have more privacy so her husband wouldn't be able to her their conversation. She closes and locks the door behind them. 
Krystal's heart is racing as she doesn't know what to do in this situation, but she has to stay firm. She turns her around and sees her nephew sitting on the bed with the most shit-eating grin.

"How did you...access my phone?" She asked.

"It's not my fault you don't have a passcode on there. I mean come on who does that?" He replied with a smug look. "But I do have a question for you."

"What is it?" She asked nervously but still standing firm.

"Does Uncle Fox know?" He asks still have that shit-eating grin on his face.

Krystal looked down, not wanting to look at Tails in the eyes.

"I'll take that as a no." He smirked while still scrolling the through her phone.
"Give it back!" She demanded. 

"Here!" He throws it back to her and she catches it. "I already saved those videos and pics on my own phone."
"You little shit!" Krystal looks at him like she wanted to murder him.

"Look, I wont tell Uncle Fox you basically been cheating on him with you guys son." Tails says.
"Wait...really?" She says starting to feel more delighted.

"Yeah, I wont...not unless you show them tits you have?" Tails said trying to coerce her.
This really pissed her off on how much of a pervert Tails was being, so she slapped his face out of anger. Tails rubbed his face and you can see a red hand print on his muzzle but he reforms his smile.

"You know what....for that, I can to touch them as well!" He says.

"Are you seriously making me do this?" She asked her face being all red.

"Yes, and if you refuse, then I will show your husband all those nude pics and the sex tapes with your own son." Tails threaten.

She takes a deep breath and then pulls her shirt up, and exposes her tits to him. Krystal never felt so embarrassed as a grown adult, but here she was letting her nephew see her tits.

"Ohhh wow!" Tails said with a grin on his face. The two tail fox reaches out and squeezes her breasts, making her yelp in the process.

"Hey now! They're sensitive!" She states while blushing.

Tails was admiring her double-Ds, he had never seen a woman so big. And he was also shocked at how soft they were when he groped both of her breast.

"Damn! You really got some nice tits here auntie!" He says with lust in his voice.

Krystal had her hands over her head, fully having her chest front and center for the pervy little fox.

"Look I am letting you touch me this once, AND ONLY ONCE! Don't think you own this body, when you don't?" Krystal says firmly.

Tails wasn't really paying attention to her as he was more interested in the big boobs right in front of him. "Oh? I think you do own you! Because I can tell your the type of woman who's really a slut in disguise."

Krystal gasped when he heard her call her that. "How dare you!" She said in a angry tone.

"What? You are. I can tell just by looking at your son. You guys been fucking for a long time, right? So I bet your pussy is used to the feeling of being filled up by a big fat dick, right?"

"I am not a slut!" She says trying to convince him, and herself.

"Oh yes you are! You're a good little slut who likes being ordered around! And if I had to guess I bet Uncle Fox isn't dominant enough with you? I bet that's why you went to look for another dick to jump on." Tails says.

"You're wrong!" Krystal shouts.

"Am I? Tell me, what made you want to jump in bed with my cousin Marcus, huh?" Tails asked smugly while still pinching her nipples and massaging her breast.

"I-it wasn't my fault." She stutters.

"Really? So it's his fault that he was fucking his mother? I can't believe you guys been at it for years."

"I know..." She sighs.

"Tell me, what happened to start this?" He asks curiously.

"It was his father's birthday and I was feeling very lonely. Fox and I have been having a dead bedroom for a while now. But since it was my husband's birthday we went drinking with the gang. Fox has always been a lightweight. He didn't have that many bears but when when got home he passed out on the couch..." Krystal was nervous to continue her story.

"Don't be shy auntie, I am dying to know what happens next." He says in a flirty tone.

"Well I guess....Marcus didn't realize we were home, so I went to his room to announce we're back and I caught him masturbating to porn on his laptop. I saw his cock and how huge he was, compare to his father and well...being drunk as I was...I came on to him and well..." Krystal couldn't finish her story.

"You fucked?" He asked

"Y-Yeah..." 

"Heh, how typical, you ladies say size doesn't matter until you finally had a big dick inside of you!" Tails said as he starts licking her nipples.

"Ngh! Oh!" Krystal moans as her nephew was now suckling on her tits. "Tails...please...I am a married woman!" 

"Please, that went outside the door the moment you decided to fuck your own son." Tails tells her as he continues to suck on her chest. 

"Enough!" Krystal pushes his head away, a string a saliva can be seen connecting  to her right nipple to his mouth. "Are you satisfied now?" She asked angerly.

"No and I know you're not either! I bet your craving a big dick right now, aren't you auntie?" Tails asked smugly.

"Tch, please I can tell you are one of those guys who brags about having a huge dick but actually-" Before Krystal could finish her sentence Tails whipped out his thick large cock.

"Oh wow! Oh my! Y-you're just as a big as Marcus." She says while blushing.

"Heh, and here you were thinking I was lying. See what happens when you don't judge a book by its cover." He says in a sarcastic tone.

"Oh my...you boys nowadays are sure are hung! I wanna say it's family trait but that's clearly untrue with my husband down there." She says.

"You wanna touch it?" He asked smirking.

Krystal licked her lips, she was starting to lose control of herself. This young cock in front of her is just so tempting, and she was getting hot.

"Oh fuck it!" She dropped down to her knees and wrapped her soft hand around his shaft.

"Whoa! Hey!" Tails was surprised at how quickly she was willing to touch his cock.

Krystal wasted no time and took his whole cock into her mouth.

"Haaah!" Tails moans, and was shocked at how good it felt. Krystal was really devouring his cock. She never realized how hungry she was to have a huge cock in her mouth again. With Marcus being gone all summer she never realized how much she needed this.

Krystal had her eyes closed, and was focusing on the cock in her mouth. Her tongue was lashing at the underside of his dick, and the slurping sounds she was making was quite audible. The sounds echo throughout the room along with Tails moans. 

Krystal was making a puddle under herself as her vaginal juices were dripping from her body. Tails noticed this, and pulled his cock from her mouth, with a pop sound.

"Hey! I wasn't done yet!" She said.

"Oh, I know, but your soaking the floor, so I figured we could move things along, ya know?" He said with a smirk.
Krystal stood up and began taking off her clothes. After a few minutes she was completely naked, and showing off her slim, yet curvy figure.  

"Fuck..." Tails said under his breath, as he admired her sexy body. He couldn't stop staring at her huge rack.

"Like what you see?" Krystal asked in a seductive tone.

"Yes!" Tails said while stroking his dick, looking at her ass and her massive breasts. "Get on all fours on the bed!" He ordered her.

"As you wish." Krystal gets on her hands and knees on the bed and Tails moves in close, and positions his dick against her pussy.

"Oh...your dick feels so hot." Krystal says in lust as she can feel the tips of his cock circling around her pussy lips.

 "Please Tails, please put it in me, and stop teasing!"

"Beg!"

"Please Nephew, let me feel that large cock in my pussy, please fuck me!" She begs.

"Good girl!" Tails slams his entire dick into her pussy, causing her to scream.

"Ahhhh fuck!"

"Hoooh damn, that's so tight." He moans as he was fully hilted inside of her. The two-tail fox can feel how tight her pussy is, and how it's squeezing around his shaft.

Krystal's eyes were closed, and was panting hard, because Tails was bigger than she was used too. It's been awhile since she last had a big dick inside of her.

"Haha, you like that, slut?" Tails said as he begins thrusting in and out of her pussy.

"Yes, oh yes!" Krystal moaned.

"Your pussy is so good!" He moans.

"Ahhh! So good, nephew! You're such a naughty boy, and you are so much bigger than your uncle! Oh my god!" The blue vixen felt so much pain and pleasure, she feels her nephew's cock hit against her cervix.

"Oh yeah, that's it, keep telling me how good my dick feels, because you like it, don't you slut?" He asked as he spanked her ass.

"Yes! Ahhh! Yes I love it, I love how big it is, I love the way it's hitting my insides, please give me more!" She moaned.

"That's it, beg some more! Beg for me to fuck you harder!" He shouted as he was slamming his cock faster inside of her.

"Yes! Fuck me harder, please!" She cried.

"Yeah, take my fucking cock, you horny bitch!" He spanks her ass hard again.

"Ahhhh! More!"

Tails was pounding his aunt so fast and hard, that the bed was creaking underneath them. They were both sweating and their scents filled the air. The sound of their body's clapping with each thrust filled the room with so much noise along with their moans.

**Meanwhile downstairs in Fox's office**


Fox stretches in his computer chair, he stares at the screen seeing all the reports he's done so far. 
"I should really take a break." Fox says as he gets up from his seat and heads to the kitchen. He starts making him a sandwich. 

"I hope Miles is settling in okay. It's years since we saw each other. But he still seems like that sweet kid. " Fox then hears yelling upstairs. "Or...not I guess?" He hears both wife and nephew yelling at each other but the walls are so thick he can't make any words out.

"If there are arguing I can already tell Miles is not gonna win that argument." He chuckles to himself. "She knows how to deal with disrespect!" Fox thinks to himself as he remembers all the time Krystal took Marcus into his room when he was being disrespectful and handle him one on one in private.

"She's a hot head sometimes, but I am lucky to have her." Fox finally finishes his sandwich and goes back into his office to work, completely clueless to what's actually happening.


**Back upstairs in the guest room**

Both Tails and Krystal are going wild on each other. Their moans filled the room, and Tails was really ramming her hard.

"You like that? You like the way your nephew's dick is slamming into you?" He asked.

"Oh fuck, yes I do, nephew! Please keep fucking me, keep fucking your horny aunt, please!" She said in a submissive tone. 

His balls keeps slapping against her ass with each thrust. Tails was getting tired, and Krystal could tell.

"Nephew, please let me on top!"

"Why should I?" He asked.

"C'mon baby, let your aunt take things from here. Rest on the bed while I ride you!" She says seductively.

"Hm...alright, slut. Show me what you can do." He lays on the bed and Krystal turns around, and lowers herself on his dick.

"Haaaah!"

"Mmmm yeah, that's it. Ride that dick!" Tails said, watching his aunt riding him like a cowgirl. Krystal bounces up and down on his dick, while Tails has a good look at her tits bouncing up and down.

"Yeah, just like that, bitch! Ride my fucking dick!" He slaps her ass, which makes her moan.

"Ahhh! Tails! I love this, I love this cock! I'm not letting it go, ever!" Krystal says in lust.

"Oh really? Then maybe we can work out a deal where we can fuck every day. You know, when I come visit or something."

"YES! We can work something out. Just as long as we get to fuck like this every time!"

"Deal, whore!" Tails said with a smug look on his face.

As Krystal keeping bouncing on top of Tails, she finally starts to reach her climax.

"Tails! I'm gonna cum!"

"FUCK! ME TOO!"

"AHHHHHHH!" She screams as her pussy clamps down on Tails cock.

"Oh, FUUUUUUUCK!"

The two foxes climaxed together, The older vixen's body spasms and trembles as her nephew shoots rope after rope of cum into her womb.

After their climax subsided, Krystal gets off Tails, and his dick falls out of her pussy with a wet pop, covered in a mixture of his and her fluids.

"That was amazing, Tails." Krystal said panting.

"Yep, definitely worth it!" He said as he was still catching his breath.

Krystal laid beside him. Both foxes were staring at the ceiling panting heavily.

"Well, this is the first time in a long while since I had a huge cock like that."

"So...about that deal?" Tails asked with a giant smirk on his face.

"Oh....right..." She sighs.

"Heh, I am not letting this go, now that I had a taste of your sweet pussy." He said as he reaches for his phone and shows her the sex tape he took.

Krystal wanted to a feel ashamed for what she did, but she was honestly left satisfied. 

"Okay...you win you two-tailed freak! You can have me when you want me." She said annoyed looking away from him and blushing. The post nut clarity was finally hitting her on how slutty she is and the fact she just cheated on her husband.

"Good! Cause I will definitely be wanting you a lot." Tails smirks.

"You little pervert." She says still not looking at him with her face still red.

The two of them get dressed. Krystal leaves the guest and heads towards the master bedroom. She sees fox just relaxing on the bed and watching tv.

"Oh...honey...did you get those reports done?" Krystal asked trying not to seem suspicious.

"You okay babe? You're face is all red are you coming down with something, also why is your hair a mess?" he asked his wife.

"Uhh well, I was having a conversation with tails and I got a little angry and started yelling." She lied.

"Oh, well, don't let him get to you, I know he's not a bad kid, but he has a bit of a mouth." Fox said.

Tails then came out of the guess room. He had a smug look on his face.

"Hey Uncle, how are you doing?" Tails asked.

"Pretty good, bud. Did you get settled in okay?"

"Yeah, it was no problem at all. Me and your lovely wife were just having a chat. Isn't that right, Krystal?" He asked in a mocking tone.

Krystal just glared at him. "Yes...YES! Just a nice chat...to catch up with Tails after all these years!" She said through gritted teeth.

"So nephew, you want to hang out with me today?" Fox asked.

Tails just shrugged his shoulders.  "Sure why not? You know Uncle I was pretty much iffy about staying here all summer with you. But now I think I am gonna have a great time, here!" He gives a knowing smiling to Krystal.
Krystal gave an uneasy smile. "Yes, yes indeed!"

This was gonna be an amazing summer of the two-tailed fox. He had so much more planned and he couldn't wait to continue cucking his Uncle Fox more.


The End.
