After I Comforted My Younger Stepsister Who Had Her Boyfriend Taken From Her, She Started Becoming Obsessively Sweet - 15

Chapter 15: Making a Complete Mess

ーーーーーーーーーーーーーーーーーーーー

Shikino led me by the hand to her room. It had been a while since I was last inside her room. The interior hadn’t changed much. There was just the basic furniture. A study desk with a chair, a bed and a bookshelf. In this room, Shikino studied everyday. She scrolled on her phone, slept, and did all sorts of other things in this room everyday. Under normal circumstances, this would be the perfect chance to start talking about the things in her room or maybe saying something like,”How nostalgic,” then I could let the conversation flow from there. But of course, the reality wasn’t that simple. 

As soon as we entered the room, Shikino locked the door behind her and leaned her body against mine. Caught completely off guard, I ended up getting pressed against the wall beside the door. The curtains were drawn. The faint glow of the setting sun cast a soft orange hue across the room, coloring everything within it in soft color. Within this dim light, only the sound of our breaths filled the space. My breaths were slightly ragged while her breaths were soft and steady. My heart was pounding wildly, like my heart was about to burst out of my chest. 

I need to say something. 

Trying to escape this awkward situation and to somehow appease my racing pulse, I raked my mind to find something to say. Just as I was about to say the first thing that came to my mind, Shikino spoke first. Her voice was so soft, barely a quiet murmur.

“…Onii-chan. Onii-chan, have you ever tasted a sweet kiss before?”

“…Huh?”

“You know, a kiss that makes you feel so happy you could melt. A kiss that makes you want to keep pressing your lips together with that person forever. Have you ever experienced a sweet kiss like that?”

“Tha-That’s… I….”

“I haven’t. In fact, I’ve never even kissed a boy even though I used to have a boyfriend.”

“…Huh? Then when you were dating him, you—”

“Are you saying I should’ve try it with him? Fufufu… Onii-chan, you’re so good at lying about your own feelings, huh?”

“Wha-Wha-?!”

I could only respond in chopped words, feeling flustered as I stared at her. Meanwhile, Shikino continued on, complete with a mischievous and yet somewhat demure giggle.

“Onii-chan,if you were to see me kissing another guy, of course you would get jealous, right? In fact, you might even cry, right?”

“…!”

“Onii-chan, I know. I know that you really, really love me. I know everything.”

“…Yo-You…! Shikino, just wha-what are you talking about…?! Why are you teasing me now…?!”

“I’m not teasing you. I’m just stating facts…”

And just like that, I completely let my guard down since I thought she was going to continue speaking. I ended up allowing my little sister to inch closer to me. 

“…Mmnh…”

“-?!?!”

Shikino suddenly pressed her lips against mine. It happened so suddenly that I didn’t understand what was going on for a moment. My little sister was kissing me. Just like Orihara-san, she kissed me without any hint of hesitation. It was a confident kiss, a collision of lips. However, Shikino didn’t stop there. 

“Fuah… Onii-chan…”

“…?!”

Something slipped between my lips. It was Shikino’s tongue. Crossing the border of my lips, Shikino was entwining her tongue with mine.

“Shi-…. Shikino…! Tha-That’s…!”

“Mmhh~”

As if to block any escape route I had, Shikino grabbed the back of my head and gently guided me to deepen our kiss. A sweet moan escaped her lips. There was nowhere to escape. Surprised, I was trying to resist her kiss at first, but gradually, all of my sanity melted away within these honey-like kisses. 

“Mmnh… Haah… Onii-… -hyan… Nnh…”

My stepsister was so adorable. 

“Nnghh?! Nnhghh-!??!”

By the time I realized it, I was already responding to Shikino’s kiss. I entangled our tongues together. A locked room. A space with only the two of us existed. A relationship with my stepsister that I couldn’t tell my parents about. A pair of lovers.

The words that my little sister kept repeating and the way she kissed me was making me more daring. The sweet kiss Shikino mentioned was happening now. I found myself lost within this sweet kiss. The table had turned. Before I realized it, I was seeking her out, more strongly than how Shikino sought me even though she was the one who had initiated the kiss. I grabbed her head to pull her closer to mine. While catching my breath within kisses, I repeatedly entwined our tongues together. 

“Hyauh…. Haa… Haa… Onii-chan… I… I already…”

“…But Shikino, weren’t you the one who kissed me first..?”

“Yeah, but… M-My waist….Nnmhh?!”

No matter what she said, I had no intention of letting her go anymore. As if I was assaulting Shikino, I kissed her over and over again. Our tongues intertwined together. I was well aware that her waist was reaching its limit. Shikino’s hips had been trembling since a while ago, as if her hips were going to give out at any moment. Her eyes were dazed. She was just staring blankly at me and yet, I followed my already shattered sanity and continued to desire my little sister. This… This must be a punishment. A punishment against Shikino’s abnormal desire toward me.

I loved her this much, even though she had been so indifferent to me, my feelings remained the same. I had always directed my feelings toward you. And now… At this very moment, she could finally feel how deep my love was with the very essence of her body and if her knees had to go weak because of it, so be it. Even then, my desire for her was still running deep. She might lose consciousness because of it. 

I love you so much to the point Orihara-san won’t be able to approach us out of whim anymore. Yeah, I see.

It finally clicked. How could I keep Orihara-san away? The answer was simple. 

“…NNh~ I-I can’t…”

“…! Shi-Shikino…”

The moment my support on her weakened, Shikino slumped down to the ground. Her eyes still dazed and her mouth was partly open. My little sister was staring blankly into the void. I looked at her calmly and eventually crouched down to meet her gaze. Without uttering any word, I gently stroked her cheek. Shikino’s body twitched in response. 

“Hey, Shikino? Shikino, do you think I’m a decent person?”

“…”

There was no response from her. Her body was still trembling slightly, probably lost in the afterglow of the kiss. I moved my hand from her cheek to her hair, gently stroking her fine, lustrous black locks. She was truly beautiful.

“Unfortunately, it seems I’m not a decent person at all.”

“Fue…? Nnh!”

I slowly pushed my index finger into Shikino’s slightly parted mouth. Then, I told her to lick it. 

“Lick it, Shikino.”

Confused and yet overflowing with love, my little sister obeyed my command readily. A look of ecstasy began to appear in her eyes. Something that hadn’t been there just moments ago. While suppressing a grin, I whispered her name into her ear.

“Shikino?”

Once again, my little sister’s body twitched in response. I continued on. 

“I’ve thought of the best way to keep Orihara-san away.”

“…Huh?”

“And that is by…”

I just had to make her realize I had turned Shikino into a complete mess.
