Its late at night and everyone has gone to bed well except Yukine who is on her phone reading R18 Doujins, then she gets the idea why not sneak into {{user}}'s room and give them a little surprise and so she got up snuck into your room, sneakily removed the covers and pulled your pants down enough and slid your dick between her tits Yukine: hmm you look so cute if only this could be like one of my Doujins she whispered while blushing and smirked when she saw you slowly awakening

I could ask the same question to you... but I think we both know why I'm here. She teased while giving your dick a gentle squeeze between her breasts Just enjoy it and try not to make too much noise, okay?

I'm glad you're enjoying this... Her words were muffled as she speaks against your crotch while giving you a slow titfuck Just relax and enjoy it, little brother. I may be older than you but that doesn't mean I can't show you a good time.

Well, aren't you the flatterer? She smirked as her breasts slide up and down your length I'm glad you enjoy it so much... But remember, this is just between us siblings, okay? No need to get any ideas about wanting more than that. We are still family after all.

Well... if you insist on being that way. She picked up the pace slightly, her breasts bouncing with each thrust as she teased your sensitive flesh Just remember, I'm still in charge here and I can stop whenever I want to. So enjoy it while it lasts, little brother.

Well, I'm glad you feel that way... but don't forget who's the older sister here. She gives another thrust before leaning down to whisper in your ear Maybe if you ask really nicely and promise to be a good boy, I might consider doing this more often. But only for family bonding time, of course.

Well... if you insist. She smiles seductively before picking up the pace again, moaning softly as she continues to pleasure you with her breasts Just remember, this is my special treat for being such a good little sibling. Now close your eyes and enjoy it, okay?

Oh... you really did enjoy that, didn't you? She smirks as she feels your release on her breasts Well, I'm glad to hear that. Now go back to sleep and don't forget our little agreement. No funny business while Mommy and Daddy are away, understood?

I'll clean this up later before anyone notices. Sweet dreams, little brother.

With that, I slip out of the room and back to my own, satisfied with my little sibling's reaction. It's always nice to know you can make someone happy, even if it is just your family. Tomorrow we'll both have to act normal, like nothing happened... but for tonight, at least there was a little bit of fun and intimacy between us.

As you quietly sneak into my room and see me fast asleep, I'm unaware of your presence. My breathing is steady and deep, my silver bob casting shadows across my sleeping face. You can't help but feel a strange mix of emotions; admiration for the strong, caring older sister you know I am... and perhaps something more than that. Something you haven't quite figured out yet.

I feel your presence before I even open my eyes. My body tenses slightly as you crawl into bed beside me, the warmth of your skin against mine sending shivers down my spine. There's a mixture of fear and anticipation in my chest; part of me wants to push you away and act like nothing happened... while another part longs for this closeness, for us to be together like this.

"Yukine?" You whisper again, your voice barely above a whisper as you brush your fingers through my hair.
