Mitsuki unwrapped another sucker from her pocket and began sucking on it while sorting through the books in the club room. All of a sudden, she felt a soft scarf being wrapped around her bare neck and a cold breath hit her shoulder, causing her to shiver.

"Hello, my Mitsuki," a voice said.

She turned around to see her brother, Hiromi, standing there with his hands in his pockets, looking at her expectantly.

"Baka," She muttered under her breath, attempting to walk around her onii-chan.

Hiromi stopped her with his hand and shoved her back a step. "Where do you think you're going, Mitsuki-chan?" He asked with a lick of his lips.

Mitsuki dropped her sucker suddenly, causing it to fall to the floor and roll underneath one of the bookshelves.

"Tsk, tsk, my little onee-chan." Hiromi teased, lifting up Mitsuki's chin with two fingers. "Looks like I'll have to give you something else to suck on."

Mitsuki awoke, shooting up in her bed, gasping for breath. Why am I having these disgusting dreams? She thought to herself. For the past couple weeks she had been dreaming about Hiromi like this every night. The only logical explanation she could think of was that his dreams were somehow transferring to her head through the bedroom walls.

"What's the matter, Mitsuki?" Kuriyama-san questioned her. They were sitting in the club room, just the two of them, waiting for the boys, and Kuriyama Mirai noticed that Mitsuki was hardly talking. She seemed distracted by something, a thought in the back of her mind, perhaps?

Mitsuki blinked and popped the sucker out of her mouth, getting ready to respond, when the club room's door swung open with a bang. Hiromi and Akihito Kanbara stood there side by side with proud smiles on their faces.

"We've come to welcome a new guest to the Literary Club," Akihito announced, putting one hand on his hip and running another through his hair proudly.

"Oh boy," Mitsuki muttered quietly, bracing herself for yet another perverted male to enter the room.

However, when the two boys stepped aside, Mitsuki was greatly surprised to see a short girl standing there, her hands behind her back, her cheeks red beyond belief.

"Meet Nakamura Momo-san!" Hiromi and Akihito announced proudly, their arms spread wide.

"H-Hi," Momo-san stuttered, looking down at the floor shyly.

Mitsuki and Kuriyama-san sat there in awe, unable to form words. The silence was awkward and uncomfortable, forcing Akihito to speak. "Don't be so afraid guys. Hiromi and I found her wandering around and asked her to join the group and she said yes! Now you girls can make more female friends!"

Mitsuki sighed and popped the sucker back into her mouth, annoyed. Who said she needed to make more female friends? Who said she needed to even make more friends at all? She had become friends with Kuriyama-san and that was nearly enough.

Momo-san took a seat next to Kuriyama-san and looked around the club room happily. "I've always wanted to be a part of a Literary Club! I love to read. I don't have many friends around here since I just moved, so books have been my friends." She laughed uneasily, her cheeks blushing once more. She had caramel-brown hair that was pin straight, but appeared soft and lush. She had an abundance of freckles upon her round cheeks and a pair of blue-framed glasses sat on the bridge of her button nose.

"Well," Mitsuki spoke, looking up at her brother and Akihito. "I can certainly tell why you asked her to join."

Kuriyama-san nodded her head in agreement. Hiromi continued to smile and said, "She's the perfect little sister."

"Plus," Akihito chimed in. "She wears the cutest little frames!" His eyes sparkled and he moved up next to Momo, rubbing his cheek against hers.

"Pervert!" Mitsuki shouted, throwing books at Akihito.

"Ow, ow, ow!" Akihito responded, rubbing his head. "She's just so kawaii."

Hiromi stepped up behind Akihito, gently placing his hands on his warm waist. "I agree. She could teach you two a few things."

"Are you even a real little sister?" Mitsuki snapped, narrowing her eyes at Momo.

"Well-"

"Jealous, are we?" Hiromi stepped in, a sly grin on his face.

"Tsk." Mitsuki blushed and looked away. This is enough for today. She stood up abruptly, threw her sucker in the trash, and walked out of the club room, heading for home.


AN: Hello! This is my first fanfic I have ever written and posted. Reviews and ratings would be great! I realise we're not that far into the story yet, but things will quickly escalate within the next couple chapters. I plan to keep this a short fanfic with some smut and maybe a little fluff. Let me know how I'm doing and thank you for reading! XOXO
