[No one's POV]
Y/n was still carrying Jyuka to his own personal room, while she had a smile on her face. Somehow, y/n kinda like her butt rubbing on his manhood. He felt embarrassed to admit it, but he always thought that she had a very nice ass. After unlocking it, they entered and y/n decided to asked her something..

Y/n: Can I put you down on my bed now?

Jyuka: Nope.

Y/n: Please?

Jyuka: Hmm...ok. but i have to sit on top of you

Y/n walked close to his bed and sat on the edge with his stepsister still clinging on him, while sitting on his lap..

Jyuka: Umm..

Y/n: You can tell me anything. I won't laugh at you.

She sighed as she nodded, she knew that she could always trust y/n on different things. She inhaled a lot and exhaled as she prepares for the worst.

Jyuka: Y/n..

Y/n stared at her, he didn't move or turn, he was serious. Jyuka notices the seriousness over his face.

Jyuka: Y/n... I-I love you..more than a brother.

Y/n was somewhat surprised at her words, but decided to play the dense card.

Y/n: M-more than a brother? But why?

Jyuka: You've have been the only man in my mind that i felt affectionate to. You help me with problems, you always watched over me and protected me.

Y/n: Of course i do that. You're..too precious for me to lose. And i I always find your attitude adorable.

Jyuka: *blushes* R-really?

He nodded, which made her cheery. Y/n tried to wiggle free go have more space, But Jyuka whined kept hugging him tightly as she was carried away by her brother's masculine scent and the touch of his broad muscular body.

Y/n: *thoughts* She really does love me this much. I wonder..

Y/n reached below behind her and squeezed her firm butt, which made her moan, blush and tighten her hold around him. He realized that his sister showed no disapproval towards his arousal. He always loved his stepsister dearly, he wanted only to protect her from harm and bring her happiness.

Jyuka: Y/n..

Y/n: Yeah?

Jyuka: Do you think I'm beautiful in your eyes?

Y/n: Are you kidding? Of course i believe you're beautiful, why do you need to ask?

Jyuka: Do you feel love for me..*twidles her fingers* in more than as a sibling?"

Y/n: After today, of course I love you. It'll be wrong to not accept the feelings of a hot girl like yourself.

Jyuka: *smiles, then whispers in ear* Then show me how much you love me with passion~ I wanna see your perverted side..

*Warning: Incestive Sour Fruit inbound! READ AT YOUR OWN RISK!!*

[Y/n's POV]
We both collided our lips together kissing each other I pressed my tongue asking for entrance. She didn't accept but that didn't stop me. I grabbed her buttocks and she yelped giving me the chance slipping my tongue into her mouth she was surprised but applied.
I hear her moan into the kiss making my member hard. we both started to undress barley breaking our kiss soon i was in boxer and she was in thin blue bra and panties. We both parted for air and looked at each other and smiled.

Y/n: Wow..you kiss like a pro.

Jyuka: T-thanks. Mind if I get it started?

I nodded, as she shifted positiond where i can see her panties in front of me. I looked down as Jyuka slowly pulled down my boxers. My member flung out she was awe at the size(12 Inches), but soon focused on what she need to do. She unhooked her bra and thrown it on the floor. Jyuka looked back at me with lust in her eyes she looked at me, wrapping her plump breast around my member and said..

Jyuka: You are gonna love this, bro.

She went to putting the top of my member in her mouth using her tongue and started to suck my cock and used her breast to message it.
I moaned making her more and more horny she started to go quicker with messaging my cock and sucking harder,swirling her tongue around my tip enjoying the pre-cum coming out. My cock twitched at a certain time when it happens..

Y/n: Jyuka..i-i'm about to-

I couldn't finish my sentence when i came in her mouth. She pulled out coughing out some cum she looked at me with a smile

Jyuka: That actually feel nice. And you can tasted sweeter.

Y/n: Glad you like it. Now it's my turn to pleasure you.

She looked at me nervously, before i took off her panties and looked at her wet womanhood. I got closer and gave it a lick at her clit, I heard her shudder and gasp in pleasure and griped the bed sheets. I smiled and continue to lick her wet cavern while she moaned my name, while I was licking her clit. I slid two fingers into her making her gasp. I picked up the pace of bringing my fingers in and out of her and my tongue tasting her from inside out.

Jyuka: Y/n!!! *squeals and moans loudly, then came on my face*

Y/n: *swallows as much as he can*
You are such a squirter..*spanks her ass and squeezes it*

Jyuka:*moans* It's your fault for making me feel this good. Let's get to the main thing..

Y/n: Ok..but first. *grabs a condom from outta nowhere, opens it and places it on member* There.. now lay down on your back.

Jyuka did just that, but also had her legs spread like a invite to fuck her..

Y/n: You best prepare yourself

I aimed my rod at her entrance and looked at her for permission. She nodded, and I prodded her genitalia's lips open little by little until I was at her hymen. I then teased her a little. I could feel Jyuka moving her hips downward trying to push me in deeper. 

Y/n: *thoughts* Damn.. She really horny for this

I then made a light push and breached her hymen, riding it for good. She then squealed in pain and pleasure. I then began gyrating my hips slowly trying to be as gentle as possible she was mewling like an alley way cat she looked at me and gave a lusty look and a heart warming open mouth smile
I smiled at in return and started gyrating my hips faster and faster Jyuka leaned forward and wrapped her arms under my arms with her hands on my shoulders and giving me a kiss. My thrusting soon got harder and faster she leaned her head back with her eyes closed and mouth open moaning in pleasure..

Y/n: Ahh, God..

[Juyka's POV]
I can't believe I'm actually doing it with the man I loved. This is a dream come true.

Jyuka: Ahh~~pound me more!

He then picked up the pace, and started to suck on my left breasts while groping the right..

Jyuka: *moans loudly and stratches his back with her nauls* Y-y/n..more!!

I felt him go deeper, and his member starting to twitch..

Y/n: I'm about to cum.

Jyuka: Do it~

He nooded and thrusted faster and deeper. With one last thrust, he cam directly into my womb, making me moan in ecstasy and wrap myself around him . I was about to scream out loudly but he quickly covered my mouth with his right hand.

SAFE!

Jyuka: *removes hand from her face and pants* That...was... amazing *lays on his chest*

Y/n: Yeah. *strokes Jyuka's  hair gently* It definitely was.

He removed the condom, tied it and threw it in a trash bin..

Y/n: I'm glad I have you in my life.

Jyuka: I'm glad too. Now we can finally be together.

Y/n: *gropes my butt* You can say that again. I never thought that you could be this sexy..

Jyuka: It's only for you..*leans close* And you alone.

Y/n: I wouldn't have our any other way..

I then smothered y/n with loving kisses and held onto him.

Jyuka: *thinks* I'm so happy....

Hiyori: Looks like they had fun.

Souji: Heh..wished they could've kept the noise down.
