What Do You Mean My Cute Disciples Are Yanderes?

"Onii-sama…" Elaria whispered, cuddling even closer to me while her hand continued to stroke my thigh.

"Hmm? What is it?" I asked, acting coy.

"Ehehe… This feels a little weird doesn't it?"

I looked around us, "The fact that we're floating in Zero-G while looking up at the stars?"

"Mmhmm~ It's also quite exciting isn't it?"

"On the contrary, this feels more relaxing than exciting, don't you think?"

"Being with Onii-sama makes me excited~"

I chuckled before pulling her closer to me, "Well… I already know what you want, so why don't you just go ahead and do it?"

Her face brightened up, "Oh! Can I, Onii-sama?"

"Isn't that what we're here for?"

She giggled before floating herself up into the air, allowing herself to slowly move towards the bottom half of my body.

She tried to pull down my pants but since we were floating in Zero-G, her action only caused me to get pulled towards her instead.

Elaria let out a yelp of surprise when my crotch ended up being pulled towards her face.

I had to use a little bit of spatial manipulation to stop the resulting force from sending her spiralling away from me.

My little sister gave me an embarrassed look which only made me chuckle, "Zero-G isn't as sexy as you think, isn't it?"

Elaria snorted, "Hmph! That's only if you are a normal mortal! I'll make this work!"

She made use of her divinity and willed my pants away, leaving me naked from the waist down.

Elaria giggled to herself before reaching forward to grasp my member in her hands, wiggling her fingers to get a good grip before she started stroking me to full hardness.

She then used a little spatial manipulation of her own to ensure I was locked in place so that she could use her free hand to pull herself closer to my cock by using my waist as leverage.

This time she pressed her face against my rapidly hardening rod intentionally, planting a kiss along the length of my shaft before moving her lips down to give each of my balls a kiss as well.

She then opened her mouth wide before sucking the tip of my cock into her mouth, letting it harden inside her mouth while her hand continued to jerk me off.

I groaned as I felt pleasure envelope me, my hips raising slightly even as the both of us continued to float within the zero gravity dome.

Feeling that I had reached full erection, Elaria started to suck on my cock for real, her head bobbing up and down my shaft.

Her hands then detached themselves from me so that she could undress herself, pulling her dress down her body to leave her completely naked.

Without so much as a warning, Elaria spun herself while keeping her mouth latched on my cock so that I was now face to face with her pussy.

What's more, she had also used her feet to wrap themselves underneath my armpits so that she could prevent us from being separated, especially considering she had released the spatial manipulation that kept me in place so the two of us were now spinning around slowly inside the dome.

I pushed my face forward to suck on her clit, causing her to let out several sweet moans even as she continued to suck me off with her mouth and making lewd slurping sounds. The two of us continued to please each other orally as we spiralled through the air with only the stars as our witnesses.

Just as I felt a familiar pressure start to build up in my balls, Elaria suddenly sped up while her hips grinded against my face with even more force than before.

Knowing that those were the signs to indicate she was also close to her own climax, I doubled my efforts with my tongue and attacked her most sensitive parts.

Elaria let out a wail of pleasure as I made her cum, my little sister managing to do the exact same thing to me as spurts of my seed shot out into the air.

Instead of falling back down, the white liquid I shot out merely floated away since there was no gravity here.

Elaria had then turned herself back around again, cuddling her face in the crook of my neck as she purred in content.

"Ahhhn~ Onii-sama~ That was so good~ But now my lower mouth feels a little empty too… Could you help?"

I chuckled at her before moving my little sister to sit on my lap.

She did so eagerly and I could feel her legs wrapping themselves behind my back to prevent herself from floating away.

Gingerly, her hands reached down and guided me inside of her, my cock pushing smoothly into her wet pussy without any resistance.

Elaria gasped and reached forward to hug me close to her, "Onii-sama… Ahhhnnn~ You feel so good~ Fuck me, fuck me hard, Onii-sama~"

I obliged and I started thrusting my hips upwards, making sure to use a bit of spatial manipulation to prevent us from floating apart from the force of my hip thrusts.

Elaria's body writhed in ecstasy before she leaned forward to capture my lips in hers, kissing me while I fucked her from below.

I held her close as I continued to thrust in and out of her, the two of us spinning around in the weightlessness of space while her love juices squirted out all around us.

In this position, I managed to move myself a little lower so that I knew my cock was rubbing against her most sensitive spot whenever I thrust into her. The effect was instantaneous as her grip on me tightened while her body seized up.

She broke our kiss and shuddered, "Ahhh~ Ahhh! Yes! Yes!! Onii-sama! Right there! I can feel it!! Ohhh!! Ahhh!! So good!! Don't stop! Don't stop!! I'm cumming! I'm cumming!!!"

I rammed myself deep inside her just as she came. At the same time, her pussy squeezed down on my cock and the pleasure proved to be too much for me as I felt my own climax hit me as well, shooting my seed deep into Elaria's womb.

The both of us held each other as we rode out our orgasms, spinning around in the dome like we were in a dance.

Elaria sighed, "Ohh… That was so good, Onii-sama… I think I came so hard I'm seeing stars…"

"Those are actual stars, Elaria."

"Oh… Ehehehe~ That's right~ Can you fuck me again until I'm seeing both the real and figurative stars, Onii-sama?"

Well, of course I can.

The two of us continued to make love while floating in the weightlessness of space, the sound of our lovemaking echoing out amongst the stars.
