It was night time at Umbreon and Sylveon's house. The fairy eeveelution just layed the last egg for their goal of having 8 children! The other 7 were already born, but some are older than others, the oldest of the siblings is Flareon who just became of age that very same day!

As their big brother, he was really responsible, taking care of his younger siblings like they would be his own offsprings. As such, he was kind of a "parental figure" to them, not quite like their true parents but still close... But tonight would be his most memorable night of his whole life.

He was in the bedroom along with his siblings, putting the 6 Eevees to sleep next to the new egg. This would be his last night in this room before moving to his personal room that still needed to be accomodated to his likings. In his mind, he couldn't wait to have his own room, why? Because recently, he had some needs to fufill that he couldn't in here, he couldn't relieve himself that close to the other siblings... Even laying on his back, body covered in leaf, he sensed his genitals begging to be stroked or rubbed against something...

Sure, he could sneak out to find somewhere else more private just for a few moments, but he didn't want to wake up the Eevees especially because of his hard penis that's hard to miss if not for the leaves that hides it despite the bulge. He could only endure it until tomorrow, he thought. But just as he was falling asleep, someone managed to enter the room quietly without being noticed, it got close to him and pushed the leaves aside without making a sound.

Flareon's cock was free from it's prison and hardened even more. But what woke him up was a gentle lick on his penis that opened his eyes wide, quickly noticing that, his mother was the one licking his private part. In a quick gasp and moan, he whispered in a confused tone.

Flareon: M-Mom...? W-What are you...? Aahhh...

Sylveon used one of her ribbons to cover his mouth and replied with a sweet smile... the rest of the ribbons handling the stroking while she talked in a quiet tone...

Sylveon: Shhh... don't wake your siblings up... I'm just, helping with your special needs... Just relax dear...

Trusting his mother, he let his muscle relax and enjoy the show his mom was giving him, still kinda embarassed though... The mom proceed to suck his balls all the while still stroking his hard dick with her ribbons. Soon enough, Sylveon gave his son the greatest blowjob she could give... Flareon shivered from the great feeling. Slippery sounds were also heard with her sucklings that increased as time goes by. He couldn't yell, but would if he could since he was gonna cum in few seconds. Instead gasp was getting more and more frequent and Flareon humped his mom's mouth, not allowing her to rest her mouth because of his son's paw pushing her head back in his mouth. He let out a soft moan as powerful cumshots filled her stomach.

Sylveon breathed heavily, looking at Flareon's satisfied face with a beatiful smile and eyes. However, she didn't seem quite satisfied herself. She made herself clear by caressing his belly, she got up and left indicating... somewhere... She wanted him to follow her and they quietly left the room.

Flareon followed his mother, he felt... the need to follow her! Upon reaching their destination. He noticed that it was her bedroom, not only that, but Umbreon, his dad, was here too! In fact, he saw upon entering the room his mom standing on top of Umbreon while he was caressing her sides, her ass was facing the entrance. This turned Flareon on a little but he was really confused at the same time.

Flareon: Mom, dad, what was that for...? I mean... aren't I... your son? Isn't that weird?

Sylveon and Umbreon was looking at each other before responding. They were sitting down now, but still sticking with each other.

Umbreon: We... did some research about Flareons, we discovered that they have a pretty high sex drive upon becoming of age... we quickly thought about you. You don't have a mate yet right? So, your mom wanted to help you, for tonight! And as it appears, you're still not satisfied yet, for that reason...

He grabbed Sylveon's hips and brought her closer to him. She was now in front of him. Leg spreaded for Flareon. As for him, he was turned on even more and approached their bed. He slowly rubbed his hard cock against his mom's pussy, hesitating to thrust inside her.

Umbreon: Now, now... You can put it inside, on two conditions... first, make sure you pull out upon reaching climax! You don't want to knock your mom up do you! And second, in exchange for that help, we'd like to have a favor from you... But let's deal with that later...

Flareon nod his head and thrust his penis inside Sylveon's pussy. Her inside was smooth and wet, allowing him to go deeper into her. He moaned as he discovers what sex feels like and soon he didn't care who he had sex with... just focusing on humping that female body as fast as he could...

Flareon: Oh... fuck yes... feels nice!

Sylveon enjoyed herself, despite the fact that her son was b
alls deep in her. Umbreon just smiled at her, staying behind her with his paws on her chest to keep her still. Sylveon felt bad for him though and started kissing him deeply while their son continued...

the three stopped for a few seconds and Umbreon picked her up to sit on his lap while Flareon repositioned himself. Umbreon's dick made his way in his wife's ass without stopping the kisses and allowed his son to continue. The two males did felt their balls touching each other as they kept it up.

As Flareon continued his way inside her, he reached her cervix and the tip was being kissed by it at each thrust. Sylveon moaned even more, she was being kissed and fucked in her two holes by her husband and also her son...

Umbreon: Ohhh... Sylvy... ya milf... even your ass is fine... I think I'm...

Flareon: Yeah, me too... I'm gonna cum...

The two let the Sylveon go. Freeing her pussy and ass from the penises... she sat down between the two whose penises were as hard as they could possibly be and faced toward her face... using her four ribbons, she wrapped two of them on each one and start jerking them off with great speed. The pleasure was unbearable and the two males both blowed a big one on her face and chest at the same time.

She cleaned their messy penises with her tongue and let them rest, one in front of her, and another behind her.

Flareon: So... what's the favor...?

Umbreon: Oh yeah, can you teach your sisters what sex is, when they get older...? I don't think they'll be comfortable if it was their parents... so I think they would be more comfortable talking about it with their big brother... as for your brothers, we'll ask one of your sisters to do that for them...

Flareon: Okay dad...! I promise... and that will be our secret...!

And so, they fell asleep on the bed tired from all the work out and orgasm... the next morning they didn't want to talk about last night, most likely out of shame. But Flareon knew what they needed from him and won't forget until everyone of his sisters has been taught what sex is... as long as they'll want to of course...

Several years later...

As years go by, Flareon's siblings grew up, and one by one, some became of age. Knowing what he promised few years ago, he was on his way to see the first of his sisters who was mature enough to talk about... adult stuff... and it was Vaporeon, alone in her bedroom and being bored...

When Flareon entered, she stood up, surprised to see him here. She saw that he was a bit shy about talking to her. But he worked up his courage and sat on the bed next to his sister.

Vaporeon: What's wrong big bro, something the matter...?

Flareon: Well... we need to talk about something... you're a grown up so I guess it's time to teach you something! Y'know what two people do, when they like each other very much...?

Vaporeon: They... go camping?

Flareon: No! Well... most of the time no... but ever wondered how our parents made us...? Well... when Mom and Dad spends good times with each other, they sometimes want to spice things up! And so, they get really close, kisses and uh... mate.

Vaporeon: What's ''mate''? How do they do that?

Flareon blushed while trying to find the right words.

Flareon: Uh... it's when a pair let's their genitals meet each other... really close! If we take mom and dad as an example, mom has a hole between her legs, like you! It's what we call a vagina, or pussy if you prefer! And dad has some sort of stick, like me, at the same place as where your vagina would be... and that come out when he's aroused. It's what we call a penis or cock! After they're aroused enough and feels like it. Dad's penis enters mom's vagina and proceeds to put it in and out until white stuff comes out of his penis... it's semen or commonly called, cum! The two decides wether they want the cum inside her or outside of her hole... you see if dad cums inside her, chances are we'll get another sibling!

After that really long explanation, she yawns as she got closer to him.

Vaporeon: explanations are boring, let's try that ourselves...! It's okay right...? As long as we love each other in some ways such as family... and we just have to be careful about avoiding the white stuff getting inside me!

His sister reached for his male genitals were they should be forced his erection. She was surprised by how big it was but smiled. Flareon on the other hand blushed heavily, hiding his sudden erection with his paws and legs

Flareon: S-Sis...! It feels... wrong... we shouldn't...!

Vaporeon: Aw don't be like that! It's not a problem as long as our parents doesn't know! It will be our little secret...

Flareon hesitated before slowly revealing his private parts to her. Still red from embarassement...

Flareon: I guess... but only once okay?

Vaporeon: Deal!

She got on his lap before sitting on it, facing Flareon. She then guided her privates towards Flareon's with a bit of his help. Her arms over his shoulders and head on his fluffy neck. She prepares herself for her defloration...

Flareon: Let's start really slowly, it might hurt a lot at first... but... you'll be okay! Promise!

Vaporeon pushes her hips down on his big bro's penis slowly. He helped her by using his paws to move her hips up and down. She screamed but not loudly... instead she gasped before squirming.

Vaporeon: Ow... Ow... it hurts...! It really hurts big bro!

Flareon: It's fine... It won't hurt now... s-see? No pain... only pleasure!

He was pushing his hips against her's as he says those words. She could confirm, opening her mouth to breath out some hot air as she rubs her head against his fluff and her tail was wiggling while he continues showing what sex feels like.

Flareon: Ah... S-Sis... you're so tight and... wet...

One of his paws changed position and rubbed her back with it as the other stays on one of her ass cheeks... few minutes later, Vaporeon removes her head and paws from his neck and shoulders. She gently pushed him to make him lay on his bed while she was still on top of her big bro, his penis still inside her tight pussy.

Vaporeon: Alright, my turn now! Let's see if I can make you jizz~

She pushed herself deeper into the penis while sitting on it. She grabs hold of Flareon's body and starts moving her body backwards and fowards each time she moves up and time. His dick was stretching her pussy a bit more which they both felt. However. They proceed with their moment together.

Vaporeon: Oooh... like.. that? Do you... like that... big bro...?

Flareon: Y-Yes... Oh fuuuck.... faster... faster!

She proceeds to speed things up, only moving up and down now, but really fast after she bend over and spread her hips to be stable... squishy sound were heard as she thrust her big bro's penis into her wet pussy... Suddenly, Flareon's head stood up as she screams with moans and groans.

Flareon: Sis... oooohhh... I can't take it...! Mmm... need to pull out...! I'm... C-C-Cumming!!

At the last second, Vaporeon managed to get off the penis before it shoots out huge loads of cum almost everywhere from her body to his, to the bed... suddenly, Vaporeon rammed the tired penis back into her pussy, smiling...

Vaporeon: Hey! Don't tell me you forgot about my orgasm! Come on, I can feel it coming! J-Just a moment please...

His penis was sensitive from all the cumming, as such, each thrust gave him some pain. However, he can't really back out now, for her sake... he just had to endure it. Fortunately, she only took a minute to finish. As she was coming closer, she yelled...

Vaporeon: Oohhh... Flareon... Flareon... FLAREON!!

She stopped her movement fell on his tired body while pussy juice rushes inside of her pussy and get's on Flareon's penis...

Vaporeon: It felt... so good... is this what mom and dad did many times...? Suddenly I envy them... however... I don't think I'm fond of penises... I don't know they feel... weird... hey big bro you're listening...?

Flareon had fallen asleep from exhaustion...Vaporeon decided to let him rest on her bed and cuddle with him for a bit...

Vaporeon: Sleep tight... big bro...

Flareon woke up hours later but not where he'd expect to be... he couldn't move his arms and legs which were spread. Upon opening his eyes. He saw that he was chained on a bed of hay stuck and confused. He screamed only to see the responsible, Jolteon... who seemed to be in a seductress mood... she caressed his body with a sinister smile. He couldn't talk to him, only being muffled by a scarf around his mouth.

Jolteon: Hello big bro... you look fine where you're standing... look at that big cock of yours... it's begging for something don't you think...?

Flareon's penis was hard. Being exposed like that can cause such things. Jolteon continued...

Jolteon: You've slept all day you slacker... we're tomorrow and today, it's the day I become of age, and I am in need on some dick! I'm sure you won't mind... since you're supposed to show me what sex is! With word, or action... I've seen you, fucking mom with dad few years ago, I was spying on you three... Ever since that, I was waiting for this moment... and now you'll get me what I want: Sex!

Just after saying that, Jolteon rushed her head to suck Flareon's dick. He moaned in his muffles, she was rough but gave overall a good head. He wanted to precum but Jolteon opposed...

Jolteon: Oh no... don't cum just yet... I want all of your seeds in me... don't worry! I won't get pregnant! I'm just craving for some... for yours big bro! I'm gonna work your sex drive really high so you can in the end... cum to the very last drop!

Flareon didn't like all of that, but couldn't do anything about it. But hey, he thought, he will bust his biggest nut yet!

Everything in her power were used to work him up as much as possible all the while preventing him from cumming... Flareon really felt heavy on his balls from all that. But Jolteon seemed to be ready to make him cum. At this point, Flareon wanted her pussy so bad and once he got what asked for... he screamed from pleasure with the muffles. Jolteon mounted him and demand to work his limited hips to cum himself.

He took on the challenge and managed to make Jolteon wet in few seconds. His muffled screams shows how close he actually is from cumming. Jolteon rested his pussy on his penis and let him shoot all of his in her... he couldn't feel the end of all the cum they stored...

Jolteon: Yess... Yesss!! Fill me up!

Once Flareon was finished, she let him free and promise to tell no one about what he did with mom and dad and what just went down... Flareon got out weirded out but feeling good nonetheless...

This was the last one before Eevee's turn... Glaceon basically discovered it herself through friends and in the end, Sylveon decided to pay his other sons a visit to teach them about sex... As for Flareon, he kept his part of the deal between him and his parents. What's new now is that... all of his sisters opened up more with their big bro. Afterall, they've done the most embarassing things together for brothers and sisters...
