>It was only for the briefest moment
>Your lips touched
>You felt her soft lips against yours
>You felt the tip of her tongue rub agajnst yours
>She's blushing profusely
>At the same time, her eyes are in a daze, as if unable to comprehend what just happened.
>So what exactly happened?
>You and your imouto Shiori were watching a scary movie together
>The two of you were holding each other
>Her little screams would sometimes come out but they weren't frequent
>You are pretty decent at horror movies so you held it in, if only to look a little cool.
>She clings to you tightly once the movie is over
>Her head buried in your chest
>You gently rub the back of her head, reassuring her that nothing will get her
>While doing that, she lifts her head to face you, her eyes are still a little teary, but she puts on her bravest face and gives you a smile
>And then it happened
>A sudden thunder storm
>The booming of the thunder caused an "Eep" out of her in surprise
>Followed by the accidental kiss that you two shared
>She tried to hide her face in your chest again
>Instead you were too close and it became the kiss mentioned in the beginning
>"O-onii-san?!"
>She's unable to comprehend what happened
>She even thinks you made a move on her.
>You apologize profusely saying things like "I should have moved my head." and "That was my first kiss I didn't mean it!"
>Upon hearing it was your first kiss, her daze ends, the ends of her lips curved into a sweet innocent smile
>She puts her small arms around your neck, bringing your head down to look at her
>"Onii-san's first kiss..hehehe.."
>Shes giggling like she just made out with her crush
>And then it dawns on you
>She practically did. You are her crush.
>Her head gets closer to yours
>"Just o-one more..onii-san."
>You gulp slowly but you can't pull your head back
>You're under her spell right now
>Your imouto Shiori kisses you on the lips once more, this time longer, your tongues intertwined.
>It tastes so soft, and sweet, like a peach, you wonder if it's due to the fruit she ate earlier.
>Suddenly, the next thunder sound booms loudly
>She quickly breaks the kiss and squeaks, almost in panic
>She bites your lip in her panic enough to make it bleed
>"A-ah...I'M SORRY ONII-SAN!"
>All traces of passion are gone, she's now on the verge of breaking down for hurting you
>You gently reassure her it was an accident
>However, that one mood that overtook your imouto never came back.
>The rest of the night was spent cuddling and watching more movies
>Every time thunder struck, she yelped just a tiny bit and squeezed you just a bit tighter than the last.
