Krystal the blue vixen was reading a book before she went to bed. Her husband Fox McCloud just came out of the shower. A towel was wrapped around his waist and some water was running down his fur. Krystal did love admiring Fox's body. He was in great shape at least even while being retired.

"Man nothing beats a long day like a good nice long shower." Fox says, and then he looks at his sexy wife in bed. He just loved the way that nightgown looked on Krystal. She was sexy as hell to him. Fox walked over to the bed.

"I am just happy you're home, honey." Krystal says. Fox leans down and kisses his wife on his lips. "And I am happy to be with you!" Fox was giving her the bedroom eyes as his hand was going up her gown. 

"I'm sure Tails is asleep if not out so I'm sure he wont bother us. So why don't we...ya know?" He smirks, and Krystal smiled. "Sure why not, it's been a while." The two started kissing and Fox was already taking off his towel. His cock was fully erect and ready for her.

The two began kissing and making out as Krystal was rubbing the fox's hard cock. Fox was moaning softly, as he was pulling her nightgown over her head. The two lovers were now naked. Fox was already fondling her big soft tits. He was squeezing them and licking her nipples.

"Quit teasing and put in me already." She said, and he smirked. "Okay you win." Fox then moved in between his wife's legs. He grabbed his cock and put it in her pussy. She was already wet. Krystal moaned, as her husband was thrusting his hips.

As Krystal can feel a bit of her husband's small cock but she's a bit disappointed how small Fox is compare to her nephew Tails. Who's been stretching her out every single day because she's been fucking him behind Fox's back. But now she's in bed with her husband and she can hardly feel anything.

"Ohh harder Fox please." Krystal moans. As Fox was trying to give it all he got, but he was just a 3 incher. He wasn't sure if he was making her feel good or not.

"Does it feel good, sweetheart." He says.

"Yes baby keep going." She says.

After a few more minutes of fucking, Fox was reaching his climax!

"Wait FOX!" She shouts

"What?" He asked raising an eyebrow.

"I want you to cum outside..."

"Why?" He asked

"Just please Fox." She pleaded.

He sighed, "Fine!" He says, and Krystal got on top and rides his little cock.

"Fuck baby that's it ride me!" Fox moans.

"Fox, your cock feels so good inside my pussy." Krystal says.

"Yes fuck yes!" He moans and Fox was about to reach his orgasm again, and then Krystal quickly got off him. She starts to beat him off.

"Ahh fuck ahh yes Krystal ahh!" He moans, and he shoots his seed on his wife's fist. Fox was breathing heavily, but he was smiling.

"How was that, baby?" Krystal asked.

"That was great!" Fox said. "It's been while since you've got me a handjob but how come you didn't want me to cum inside you,  you always let me before?"

"Well, I didn't feel like cleaning up a mess, and it's already late."

"Fair enough, well I think I'm going to go to bed, see ya." Fox yawns and goes to his side of the bed and lays down.

She didn't want to tell Fox the real reason and that was because she didn't want his little cum inside her. It just felt wrong to have your own husband release his seed inside her pussy. When it already belongs to Tails.

"Fox, at least put back on your boxers before you go to bed." She heads to the bathroom to wash the cum off her fist.

"Ughh fine." Fox puts his boxers back on and Krystal comes back.

"Goodnight Fox."

"Night." They both went to sleep.

Meanwhile...

Tails was getting tired after a long day. He was glad he had one of his workshops in this town. So he could at least keep busy while he's here with his aunt and uncle. Uncle Fox McCloud usually have him around for free labor around the house. It pisses the young two tail fox off to know end but he gets back at his uncle by fucking his wife behind his back.

Tails finally arrives back at his Aunt and Uncles house. He sees all the lights were off from the outside. He unlocks the door and heads in.

"They must be asleep." Tails whispers, and takes off his jacket. He puts his keys and phone on the table, and then he starts to get undressed. As he was about to get ready for bed an idea popped in his head. He smirked, as he was heading up the stairs.

Once he was upstairs, Tails quietly opened the door to his aunt and uncle's bedroom. He saw the two sleeping. His aunt looked so cute in her nightgown. Tails slowly walks over to the bed, and he slowly pulls the blanket down. His aunt's big breasts were exposed.

"Perfect!" Tails whispers, and he slowly moves in between his aunt's legs. Tails started to rub his hands over her breasts.
"Mmm..." Krystal moans, and the young fox kept fondling her tits. Tails was getting a huge boner. He wanted his aunt badly, he moved her gown up. He saw her pussy, and he licked his lips.

"Mmm...Tails..." She moans in her sleep. He then starts to kiss her pussy. Tails was tasting her pussy juices.

"Mmm." He moans, and he started fingering her. He was pumping his fingers deep inside her.

"Mm..mmm." She moans as she stirs in her sleep.

Tails keeps fingering her as he was licking her clit. "Ahhh fuck yes!" She moans and she wakes up and looks down. She sees her young nephew licking and fingering her. 

"TAILS!" She said in a low but loud whisper as she took a quick glance at her husband who is sleeping beside her. "WHAT ARE YOU DOING?"
"What does it look like I'm doing? I'm just having a late night snack." He said.

"Ready? Ready for what?"

"Well I just came home from work and I saw you sleeping and well, you know."

"TAILS...MY HUSBAND IS ASLEEP RIGHT NEXT TO US! What if he wakes up?"

"Well if he wakes up and sees us then so be it, but I want you right here and right now!" Tails said

Krystal looked back at her husband who was sleeping beside them. Even if they were retired, as trained soldiers they can immediately wake up if they feel something is wrong in their sleep.

"No tails we cant do it now, not here not now."

"I beg to differ." He said.

"And just why should I listen to you?"

"Because you want this too. You love me and my cock and you can't resist me." Tails said.

Krystal looked away, and her nephew knew he was right.

"Look Krystal, we do it all the time in the same bed and he's never caught us!" Tails said smirking.

"That's because he's usually out or in another room!" She says nervously.

"But we still do it." He says.

"Y-yes."

"So lets have sex." Tails said.

"We can't, if you haven't noticed my husband is right beside me, what if he wakes up?" Krystal asked him again

"Ohh so he can't join us?" Tails asks, and she blushes with an annoyed look.

"T-tails."

"I'm only kidding." He chuckles. "Look Krystal, just try to stay quiet and we will be fine."

She sighs. "Alright but let's make this quick!" She says filled with anxiety.
"You won't regret it." He said.

"Now what are you going to do to me." She asked.

"Hmm. Well I know exactly what to do." He grins, and he lifts up her legs and places her feet on his shoulders. Tails was lining up his cock to her pussy.

"Are you sure you don't want me to use protection." He said, and she nodded.

"Just put your cock in me already."

"Okay." Tails said, and he slides his cock in her wet pussy.

"Ahhh." Krystal moans.

"That's a good girl. Take your nephew's cock."

"Ahhh." She moans again, as he starts fucking her.

"God Krystal your pussy is so warm and tight!" Tails said.

"Your cock is so big! Ahhh." 

Fox in his sleep stirs for a bit which made Krystal a little worried, but it seems that her husband is still asleep.

"Fuck Krystal you feel so good."

"T-tails...don't talk so loud!" She whispered loudly.

Tails rolled his eyes not really caring if his uncle catches them in the act or not. He just wanted his aunt pussy.

"Ahhh fuck me Tails."

"You're loving this aren't you? You're loving the fact that you're being fucked by your own nephew! While your husband is sleeping right next to you!" Tails said

Krystal didn't answer she just closed her eyes.

"You know what Krystal, I don't care if my uncle wakes up or not because I want to hear your moans, and I want him to see that your pussy belongs to me."

Krystal covers her mouth she didn't want to moan too loudly while her young nephew claims her for himself.

"You're such a slut. A slut for your nephew."

"Fuck ahhh fuck ahhh." She moaned quietly.

Tails was fucking her harder and harder. He loved her breasts bouncing with every thrust.

"You love my cock don't you, slut? Answer me."

"Yes." She whispers.

"Louder."

"YES I LOVE YOUR COCK! OH GOD YES!" She screams.

All of a sudden Fox jolts ups from the bed. His vision is blurry, and he feels all groggy. He looks all the way around the room and sees his nephew on top of his wife. Fox still in a sleepy daze and cant really tell what exactly is going on.

"Tails?! Krys?! What's going on here?!" Fox asked

"Honey! Go back to sleep! I can explain later!" Krystal says.

"Yeah Fox go back to sleep." Tails smirks, and he keeps fucking his aunt.

"I don't understand? W-what are you two doing? What's going on?!" Fox was trying to talk more but  he speech became more slurred and incoherent. Eventually he falls back to sleep to Krystal and Tails' surprise.

"That...was a close one!" Krystal said as her anxiety shot through the roof.
"Yeah but hey at least he's asleep now. Now where were we?" Tails asked with a smug look on his face.

Krystal flips Tails on his back she was now on top and was riding him cowgirl style.

"Just please fuck me." She begged, and Tails resumed fucking his aunt.

"Ohh God I love your big fat tits, baby." He groans as he starts to play with her nipples.

"Ohh yes, baby play with my big tits, mmm."

"Your pussy feels so good Krystal, mmm."

"Ahh fuck yeah, pound my pussy, fuck me, nephew."

Tails was thrusting his hips as fast as he can. His balls keep slapping against her ass, as he had his hands on her hips.

"Mmm ahh fuck." Krystal was moaning loudly, but then Fox turned his head and she was scared that her husband would wake up again, but he was still sound asleep.

"Please tell you're close?" Krystal asked Tails feeling anxious again.

"I'm almost there, fuck your pussy feels so good, oh god!" Tails groaned.

"Come inside me. I want your cum." 

"You're going to get it!"

"Yes, yes ahh." She remembers to cover her mouth while she moans. Tails' cock is pounding against her cervix and just hitting all the sweet spots.

"Fuck ahhh fuck." Tails moans

"Cum in me! Oh god, yes, baby, fill me up!" She begs.

Tails thrusts into her and he cums hard in her pussy.

"FUCK!" Tails and Krystal both screamed.

Tails kept his cock inside his aunt, as his white essence painted her insides white. At the same time Krystal also reached her climax as her pussy clenches around his shaft.

The two lovers were breathing heavily as they were both coming down from their highs.

"T-that was a-amazing!" Krystal panted.

"Yes it was." Tails replied with a satisfying grin on his face.

They then heard loud snoring right next to them, remembering that Fox McCloud was right next to them.

"Oh thank god, he's still asleep. Maybe we should stop before he actually wakes up. Because the first time was just a close call!" Krystal says

"Well, he can't see anything in the dark. And we didn't make too much noise." Tails says.

"Yes....we did!" Krystal argues. "Look I know you want to keep going but I don't want to continue playing with fire! So get out of my room you little shit!"

"Okay fine!" He sighs, and he pulls his softening cock out of her.

Krystal watches her nephew as he walks to the door.

"Love you auntie." Tails blew her a kiss.

"I love you too baby!" She gives a blow kiss back.

Tails smiles and leaves his aunt's room with her sleeping husband.

Krystal then sighs and looks over at her husband, who is still snoring loudly. She smiles at the thought that Fox was a heavy sleeper and had no clue that his nephew and wife just fucked in the same bed he was sleeping in.

**The next morning**

Fox wakes up and yawns. He looks around and sees his wife Krystal is already up and wearing her robe.

"Morning sweetheart!" She said.

"Good morning." He yawned. "Wait how long have you been awake for?"

"Not too long, I've made you a cup of coffee, it's on the kitchen table." She said

"Thanks honey." Fox smiled, and went downstairs.

"You're welcome." She said.

He heads into the kitchen and sits down. He takes a sip of his coffee.

"Man Krystal always makes the best coffee."

"Morning Uncle Fox," Tails greeted the older male who was sitting right across from him while he was eating cereal.

"Morning kiddo! How did you sleep and has your aunt made breakfast yet or do I need to cook?" Fox asked.

"Well I slept great, pretty sure it was one of the best night sleeps I ever had." Tails said having this devious look on his face. "Oh and Auntie Krystal had breakfast already. She ate some sausage and two boiled eggs." He informed his uncle.

"Really, that's all she wanted? I guess she wasn't that hungry this morning." Fox said

"Oh trust me, she was hungry this morning, you should've seen her devour it. I mean man, she really wanted it!" Tails said with a devious grin and Fox was clueless as he kept drinking his coffee. "She also drink some milk as well but most of it spilled on her face, chest, and the floor."

Fox looked on the floor. "Oh don't worry I cleaned it up after Auntie Krystal went to go take a shower." Tails said still having that wicked grin on his face. He gets up and washes his bowel in the sink.

"I'm going to go ahead and work in my workshop for a while." Tails walks out the kitchen.\

"See you later kid!" Fox waves at his nephew, and he leaves.

Tails walks out the front door. Meanwhile Krystal walked downstairs dressed.

"Already dressed for work?" Fox asked. "I thought since Tails is gone for the day, we could spend some time alone." Fox pulls her in close as he was being flirty.

"I'm sorry honey, maybe later but I have work to do!" Krystal says pushing him away.

"Fine...by the way, don't judge me on this but..."

Krystal raises her eyebrow in confusion. "What?"

"Well I had this weird dream, but...it felt so real. I woke up in the middle of the night, I see you and Tails going at in our bed. I know that's a dream because I know you well enough you would never do that. But It felt so...real...thats what's so odd...about it..." Fox said.

"R-really?" Krystal stutters.

"Yeah."

"You know I would never have sex with Tails, he's our nephew that would be weird." She said.

"I don't know I'm not a psychologist. I'm not sure why I had that dream. It was just something I wanted to share but...just ignore me now I feel embarrassed." Fox said as his face was now all red not wanting to admit he liked what he saw in his dream.

She couldn't help but laugh, Fox was too cute when he was embarrassed. She kisses him on the cheek to make him feel better at least.

"Look I don't know why you dreamt that but remember it was just a dream and dreams...well...they're weird. So just ignore it for now. Okay sweetie!" Krystal says with a cute smile.

"Okay, I guess I can forget about it. But can we still have fun tonight?" He asks.

"Sure, honey." She says, and she kisses her husband and then she left for work. As Krystal walks out the door, she exhales like she ran a marathron.

"Okay as hot as last night was, that could never happen again, sure Fox may think it was a dream now but he could catch us in the future. I have to tell Tails to stop." She said, and she started heading to her car.

Meanwhile in his workshop, Tails was working on a new invention, when all of a sudden his phone rings. He picks up his cell and sees the name 'Krystal' on the screen. He smiles and answers it.

"Hi auntie! I've been waiting for your call!" Tails greeted.

"Tails listen! Last night was a mistake, we can't do that again. My husband could've woken up and saw us having sex!"

"So."

"SO?! TAILS! We could've got caught! I mean yes it was a close call but if we do it again who knows, he may wake up next time and see us in the act."

"Auntie, he's never caught us before and we do it in the same bed he's in and he has no idea, plus your husband is a heavy sleeper. So, relax he doesn't know a thing."

She sighs. "Look, we should just be more careful."

"Now where's the fun in that?" Tails said sounding mischievous over the phone.
"TAILS!" Krystal said sounding annoyed

"Look it will be fine, trust me, I gotta go!" Tails said hanging up the phone. As Tails was working on his machines in the workshop. He had some naughty ideas in his mind and he couldn't wait to do with them Krystal...
