Chapter 5: Chaotic Sexy Time

Chaos Ruler, The Chaotic Magical Dragon, nicknamed Fafnir by his partner watched over said partner in spiritual form as he slept.

And as he did Fanir could not be any more certain of his choice of partner, he was truly the one who would be the Master of Chaos.

Now though just needed to locate his fellow Chaos Ruler, though sadly he had no idea where Chaos End Ruler was. He could not sense his who was technically another version of himself. Meaning that someone was hiding him.

No matter.

They just had to find the hard way.

For now though he would focus on raising Sieg to be the perfect partner.

While the old version of the boy, would not have been worthy of him becoming his Ka, the new version.

The new one, born from two recently deceased souls having fused together and returned to life, escaping from the confines of fate, a truly Chaotic Being who would be on the same level as the Supreme King of Gentle Darkness, and the Signers of the Crimson Dragon to just name a few.

But he was starting to repeat himself, for now though Fafnir was gonna to give Sieg a reward for his recent success in gathering his Deck, and defeating that teacher in glorious combat.

And while doing so make those hidden dreams and desires of his a reality.

His dream of having a harem of beautiful mates.

Fafnir could only laugh.

He truly was a dragon, even before having bonded with Fafnir.

He was just one, even more now.

And Fafnir had already started helping him with that, marking the girl who possessed a Millenium Iten and a God Card with their brand, she was truly a worthwhile member of his hoard.

Now the mark itself was at it's lowest setting as the girl had only been defeated in regular battle and not a Shadow Game, so she was not a full-on slave. But he had still activated the rules of what happened when one lost to a dragon on Sieg's behalf.

Adding her and the other spirit to his hoard, the mark just signified that they were that, and gave some minor resistance against mind control.

It was only at the highest level, one that could only come about via losing a Shadow Game that allowed for hard manipulation of thoughts, emotions and memories.

But still there was one thing the lowest level of the mark it could do.

Namely sending dreams through the link now established with the marked.

Those dreams being particularly ones involving them mating with Sieg.

Like he was doing right now.

Sending dreams to the Yugi girl and Joan now that she had been marked as well.

And she… well it seemed that she was already interested in Sieg like that, though sadly with the Sieg of yester year those feelings would never have been reciprocated, as that one had no sexual interest in his siblings.

Which made no sense to Fafnir, they were excellent and fertile mates.

But thew new Sieg did.

He viewed them as women first, siblings second and going by his current dream he did indeed desire to mate with them.

But currently due to his lack hormones, his physical development in that regard was very, very stunted.

But that was something magic couldn't fix.

That was going to be his first gift to Sieg, a cock that would make women want to breed with him, like in those stories he used to read.

Though Fafnir was going to make it so no children could be born yet.

That was just going to inconvenience them.

And so, Fafnir got to work, transforming Sieg's manhood into what those stories called a 'bitch breaker.'

And so, as Sieg slept, his currently erect dick, due his currently very wet dream. Gave a twitch in his currently exposed underwear.

And so it grew, gaining a little bit of length, and a little girth. And did so again.

And again.

And again.

It grew every second, so soon the erect dick was to my much for the underwear to contain as it was pushed to the side and went down the right leg where it continued its growth, the nuts following as they slipped out to stopping at a size where they easily were the size of a standard apple each, while the 'banana' had stopped its growth where it just hung in the air, the now supernatural amount of blood barely able to life the now 40 centimeter cock that now leaked a steady stream of cream as the veiny cock throbbed in conjunction with its owner's dream.

Truly Fafnir was proud of his work, now it just needed to volunteer and it looked like he had one as someone was looking at the results of his handy work.

Xxx

"What the fuck was that dream?" Joan asked herself, her face flushed with both shame and arousal, her cunny still wet and aroused as she walked out of the bathroom having just cleaned herself up after she had woken up due to her pussy orgasming from having dreamt of Sieg thrusting a huge dream dick into her dream pussy.

She knew it was a dream as she knew that Sieg had didn't have a monster like that.

Or did he?

It wasn't like she had seen him naked in a few years, so maybe he could.

"What the hell am I thinking?" Joan asked herself, as she tried to suppress her desire for her brother, they weren't natural to have, they shameful and dirty. Was what Joan kept telling herself, and even if it was not so, it was not like her little brother saw her-

"Sis." Her thoughts came to a halt as she heard Sieg's voice calling for either her or Jeanne, and Joan realized that she was currently outside of his bedroom. His door slightly open, probably due to having forgotten to close it properly.

Was he having nightmare?

It would make sense if he did, he almost died.

And that was natural, she had nightmares after that night, now almost three…

No, she did not want to think about it.

For despite how Joan talked to him, he was still her little brother and she loved him.

So she pushed the door open, intending to just lay with him until he calmed down like Jeanne did and…

And…

Joan's mind froze as she looked at it.

She looked at it.

She looked at it.

Her mind was still having trouble processing the humongous erect cock that was jousting from Sieg's crotch like a deadly weapon.

It was veiny, thick and long.

It would require at least four hands to cover it length, and one hand looked it would barely wrap around it.

She could see the clear pre-cum run down the length that was almost breaking under its own weight.

The crown was red and angry with blood as it looked like it wanted to come so desperately.

How the fuck. Joan simply thought. How the fuck does the brat have such a huge cock?

She repeated that thought a few more times, as she looked at the cock that was clear match for the one in her dream, one that was twice as large in every dimension compared to the last guy she had slept with.

She.

"Joan."

He said her name.

Sieg had said her name while having an erect dick the size of a baseball bat.

Joan only took it to mean one thing.

He did like her that way.

And like that, she felt all of her feelings be validated.

All the previous shame and disgust gone as she relegalized the person she loved, loved her just like that back.

Before she knew it Joan had entered Sieg's bedroom, gotten onto that large bed of his and was now sitting on her knees, her mouth only a few centimeters away from Sieg's cock, her breath hit the cock and it throbbed in response.

What was she doing?

Joan knew this was wrong.

But she didn't care.

Her little brother was 'hurting' and so as the big sister she needed to soothe his aches.

It smelled delicious.

It tastes delicious too. She thought as she placed her lips on the pre-cum spewing head and began to give Sieg a blowjob.

"Hmm," Joan moaned as she took more and more of the cock into her mouth and throat.

It was so thick, it was a snug fit but she could get it inside.

But sadly, it became apparent her throat was untrained to take lengths of this size as she barely got to the halfway point before, she could feel herself starting to gag.

But she still had like more than twenty-five centimeters left.

Thankfully she had other body parts she could use to solve that issue.

It took a bit of wiggling but she managed to push her gown down and expose large breasts, her nipples now fully erect as she took hold of each tits and wrapped them around the remaining bit of Sieg's cock and starting giving the double job combo.

Xxx

I had to be dreaming.

I had to.

But the fact that I had opened my eyes, and actually feeling, feeling disproved that as I saw Joan give me a blow and tit combo job, serving my much-improved dick.

As it had not been that huge when I had gone to bed.

I had an actual gigantic cock now that belonged in a fucking hentai.

And my sister was now fucking blowing me like a maniac.

Joan looked me in the eyes clearly having noticed that I was now awake, but she didn't say anything she just continued to work my shaft like a Queen as…

She removed her hands from her breasts and just let them lay on my crotch. But then I felt her hands on my own, and she guided them up to her breasts. A

And my finger's sunk into the soft tit flesh, good I had wanted to touch them since I first woke up.

And now I was and I was using them to jerk off the cock that she wasn't sucking with her mouth, as her now free hands started caressing my nuts, that definitely felt bigger.

"Enjoy your gift partner." Was what I heard Fafnir say but I was unable to respond as Joan just sucked harder.

Oh god I am gonna…

"Sis, I am going to CUUUUMMMM!" I practically shouted as I felt my shaft expanded inside that lovely and tight throat of her's and soon I felt the stream of cum flow out of my dick and into her stomach.

"AHHH!" I groaned as my orgasm just continued for like fifteen seconds, I was coming such a large amount, and it was thick stuff. As I could see it leaking down the side of her mouth and her nose.

An angry dragon.

Her cheeks her bulging with cum as she slowly pulled of her mouth of my cock cleaning it masterfully leaving only a sheen of spit remaining.

Joan looked down at me and then.

I saw her throat swallowed the cum stored in her cheeks vanishing as she opened her mouth to show that the thick load of cum was gone.

My half-erect dick immediately re-gained full erectness as I started at half naked Joan, my sister's large and perky breasts on full display.

"Its still erect, even after…" She simply said in amazement, and slight horror on her red face.

"Sorry," I simply said apologetically as I didn't know what else to say as my dick bobbed and throbbed between us.

"Don't apologize for that huge dick of yours, how are you even able to hide that?" She asked.

"I…" I didn't know how to say it hadn't been like that a few hours ago.

"Doesn't matter, anyways," Joan said as she I watched her spread her legs, and I saw her pussy.

Her bare pussy with no underwear what so ever to hide from view, it was puffy and leaking, I could see her clit standing erect as I poked out from its hood.

"So brat," Joan said. "I said I owe you favor, so that favor is going to be taking that dick of yours," Joan said as she parted her lips.

Showing me her pink inside, I could see the tunnel that lead to her womb.

Her baby making chamber.

"So go a head and put it in," Joan almost ordered.

And I acted.

I didn't know it, but primal instinct guided me as I put my big sister in a Mating Press, she didn't resist, just looking away from like a blushing virgin. But that face quicky became one of ecstasy as I thrusted my cock down!

"Oh fuck you're so big!" Joan almost roared, my silver and yellow haired sister orgasming on the spot as I just fucked her with wild abandon not carruing if she actually got pregnant from this.

I just wanted to fuck my sister's unprotected womb.

And I did.

I could feel my now gigantic cock pierce her cervix as I saw her stomach bulge and stretch around my member.

I let go of her legs and went further down as I started to maul Joan's breast my size allowing me to easily lean down and suck on her titties.

There was no milk.

But there would be.

One day.

"Harder, harder, harder!" Joan moaned.

And I did, I slammed down with all my might and I came.

Filling her womb and beyond with my thick seed.

But I wasn't done. I was far from done.

I didn't know where this energy was coming from or all this semen, as it felt like I was coming buckets.

Well, I had one idea.

The one responsible for giving me this cock.

"Thanks Fafnir." I simply said mentally as I fucked Joan into unconscious as she just wasn't capable of handling my cock.

Though it wasn't long until I to ran out of energy after was probably my fifth additional orgasm, leaving Joan's womb and pussy filled with thick cum that I could I see slowly start to leak out as I pulled my cock out.

Xxx

Fuuuuuuuuuuuuuuuuuck! Joan mentally groaned as she regained conscious, she could barely feel her lower body as the brat had literally fucked her silly.

But it was so worth it.

It felt so right.

Even if her pussy and womb felt so sore.

She looked at Sieg's now sleeping form and smiled, at him as she gave him a kiss on the forehead.

And as she looked it definitely looked like he was a grower and not a shower, even if his flaccid state was the above average length of a normal penis.

But it was a cock that could fit in his pants.

Joan wobbly left the bedroom as she needed to clean herself up before she went back to bed.

Though had to clench her pussy as she noticed she was dripping thick cum down her leg, her stomach still bloated.

And as she went back to the toilet, she did not notice Jeanne step around from another corner her nightgown clung to her body from sweet, her pussy exposed and red from the jilling she had done to watching her little brother fuck her twin sister like an animal.

For a moment she thought of going in and continuing herself, but her brother was clearly spent for the night. And she had her own plan in mind for when he claimed her, for now she knew that her bellowed Sieg held sexual feelings for his sisters.

So for now she was gonna be satisfied with this.

She knelled down and scooped up the thick almost gelatinous cum that had spilled from her sister's pussy.

And Jeanne ate it.

She felt her body shudder as she came again, her body overjoyed at the consumption of Sieg's release.

She couldn't wait to get it straight from the source.

Xxx

After I had woken up, I had thought what had happened to be a dream, I've had a few of those before.

I couldn't really help it, my sisters were very hot.

But a look at my semen covered bed, and the massive flaccid dick that hung between my leg and my apple sized nut sack said that what had happened had been real.

I had fucked my sister.

I had sex with Joan.

And it had felt great despite the Hentai logic of the situation.

I thanked Fafnir for his gift.

Though I could do without the mess.

And so, I spent that morning cleaning my bed before I met the others.

Breakfast had been a little awkward as Joan just kept blushing as she looked at me, which happened throughout the entire day.

Though as night arrived and as I prepared to go to bed, I heard my door open behind me, and I turned around to see Joan enter, closing it behind.

She was only dressed in her usual sip-up dress, though after she had finished closing, she went and zipped it down, revealing that she was completely naked under neath it, her body flush and sweaty. Her pussy was on fully display, wet and dripping with arousal.

"So do you wanna continue from last night?" She asked, her nipples fully erect.

"Sure thing sis, let your little brother take care of your lust filled body," I said as she blushed even harder.

"When did you get so forward?" She asked as she got on my bed after having dropped her jacket on her floor.

"When I realized my sister is a bro-con slut," I said as I gave her tit a squeeze, making Joan moan, her body very sensitive at the moment. "And now that you got a taste last night, you this huge dick of mine to ravage you right?" I asked as I pulled out my hardening cock out of my boxers, the male genitalia barely able to fit in there.

The huge shota cock I now possessed throbbed in front of her face.

"Yes," Joan admitted as she started to make out with my length kissing it like she would a prince until she ended up at the tip and began to swallow my cock.

Though she stopped after only having a one third of it into her mouth.

And began to pull back before moved back down.

And she did that for a minute my cock tingling as it stretched her mouth and throat due to its girth.

Joan moan like a whore as she tried take more and more of dick into her throat.

"Well if you want all of it sis, I give it to you," I said as I grabbed her head and before she could object, I thrusted forward shoving my entire 40cm length into her mouth and throat.

I heard her gag and choke around my cock as I came straight into her stomach.

It felt so fucking good.

And I there until I had finished, I pulled my cock out of her skull fucked head, her face looking like the fucked silly kind as she looked absolutely dopped out.

And she threw up some of the thick and creamy cum my dick had fired into her stomach, the white substance flowing down her oh so perky tits.

"My what a slut you are big sis," I said, as I couldn't help the dirty talk as I inserted a few fingers into her absolutely drenched cunt. "Getting turned on from your little brother fucking your face, what a slutty sister you are."

"I am," She admitted, and I could tell she was just turned on beyond belief.

"You maybe be, but you are my slutty sister, so I happily give you the dick you've craving for years, haven't you?"

"Yes," Joan responded as I flicked her clit, and her body orgasmed in response. "I want that stupidly huge dick in my cunt."

"Hmm, but you have been a little bit of a bitch lately sis, so what way do bitches get fucked?" I asked.

"Like a dog," Joan responded.

"When you know what to do," I replied and Joan did as asked, she turned around, and sat all fours, presenting her dripping pussy to me like she was in fact a bitch in heat.

"Sieg, I need you." She begged.

"Good bitch, good slutty sister," I said as I aligned my cock with her pussy and thrusted in. Spreading her vaginal tunnel and smashing directly into her cervix making Joan holler.

And so, I spent the rest of the night fucking Joan doggy style.

Xxx

Luna laid in her bed as she listened to what was happening on the other side of the wall, as her bedroom was right next to Sieg's

She listened to Sieg-nii, and Joan-nii having sex.

Like they had last night, their sounds having woken her up, as the walls didn't actually stop sounds very well, especially if there was only one, and it was not one of the support walls.

And going by the sounds he was fucking her really hard.

Luna's hand moved down to her moistening crotch as she started to masturbate to the thought of Sieg having sex with her, not an unusual fantasy, it was actually her most common one.

One she had been having since she her body had started developing and she learned about sex, she had been planning to actually sneak into Sieg's bed and have her way with him before he went to Duel Academy.

Taking his virginity.

But that opportunity had been stolen from her by Joan-nee, though going by what she was screaming as she thrusted his dick into her.

It was probably best that she had gone first as Sieg's cock definitely sounded way bigger than she had expected.

She was going to need to train her pussy a bit more so that she could take it.

Hopefully her cunt would be ready by Golden Week.
