The Sadist and the Masochist

Pairing: Ryobi x Ryona

Genre: Romance

Disclaimer: I do not own Senran Kagura or any of its characters.

Author's Note: I know that title is totally obvious, but that's all I could think of at this point. Besides, there's already been a title on the "MM!" franchise, but this is totally different. Also, I'm just going to start something new here. This is a whole new story separate from my other Ryobi x Ryona story. Besides, this is Senran Kagura, right? Hehe~!

Anyways, I hope everyone enjoys this one.

"GET BACK HERE!" Ryobi demands as she chases down a certain short haired blonde down the halls.

"But it's the truth~!" Ryona teases. "You're my baby sis, Ryobi-chan~!"

"I'M NOT A FREAKING BABY!" The brunette summons her rifle and uses it as a weapon to strike at her sister. She throws it at the blonde, making it a direct hit on her back.

Ryona falls to the floor and rolls on her back as she rubs it. Her younger sister stomps over toward her after she disarms her weapon and cracks her knuckles.

"You don't call me a 'baby' like that again, you hear me!?" she growls.

"I'm sorry," Ryona apologizes. "But you're just so cute being my baby sis-" Before the blonde could finish, Ryobi grabs her by the shirt with one hand and starts to slap her hard on both cheeks with the other.

"How many times do I have to freaking tell you!?" she roars with each slap.

After about 20 hits, making her cheeks go red, Ryona's eyes start sparkling in satisfaction. I'm getting turned on again~! she thinks to herself. Please hit me more!

Ryobi pulls her closer. "You're such a pervert!" she says in disgust. With that, Ryobi tosses her across the hall about 10 feet away until she hits the floor again with a loud thud.

The blonde looks up as the younger twin stomps toward her. It'd feel great if she would stomp on my face right now, she thinks. Ryobi gets closer to her when Ryona snaps back to reality and starts running again. No time for getting caught in fantasies! However, just when Ryona is just about to run about 5 feet, she feels Ryobi's foot come in contact with her face. When she falls to the floor, face up, her smile remains on her face. Ohhh, that feels great! I've been hit…by my own sister~!

Ryobi pants from all the aggression she had put on her older sister. "That will teach you, you messy mutt!"

The blonde lets out a soft laugh. "Thank you…Ryobi-chan…"

**Later**

Ryobi sighs heavily as she slumps on her bed at her dorm room. The thought of her sister teasing her like that still floats around in her head. How dare she call me a 'baby'! she thinks to herself. Sure I'm the younger twin, but that doesn't give her the right to call me that!

Ryobi loves her sister, Ryona, but sometimes, because of her masochistic behavior, it has caused a lot of problems, not only for everyone, but for her as well. She is a sadist of the twins who loves to cause everyone so much pain physically and sexually, but she mostly does this to her own sister, just to get her under control. However, in doing so, it has caused some more problems since Ryona LOVES to get beat up. Overall, despite the m having different personalities, the heterochromatic twins care for each other deeply.

In fact, Ryobi is actually in love with her sister. It's been that way since the very beginning, but she chose to hide her feelings because of her sadistic behavior. But…will Ryona be able to accept them? We're sisters, right? she thinks to herself. Ahhh…what the hell? This is going to be harder than I thought. She plops on her bed with a long sigh and stares at the ceiling with her heterochromatic eyes and her mind filled with only her older twin.

**Next Day**

"Oh, man!" Ryobi groans as she sits against the wall after practice. "Why does Suzune-sensei have to push us so hard!?"

Ryona sits next to her with her usual cat-like smile on her face. "I thought training was a lot of fun~!"

The younger twin frowns. "Yeah…considering Sensei had to whip you like a thousand times to get your attention and help you understand."

"But that's why it's so much fun~! That feeling of the whip. Oh, it felt sooooo good~!"

Ryobi slaps the back of her head. 'Oh, shut up, idiot!"

"Hey, you two!" Suzune calls. "Training's over! Get changed!"

"Yes, Sensei!" the twins say in unison.

Both of them head towards the locker room to change back into their uniforms. However, since the twins' lockers are next to each other, Ryobi can't help but steal some glances at her sister. A faint blush appears on her face as she feels her heart beating. I don't know why, she thinks to herself. But whenever I look at her…my heart beats a million miles an hour. She's just…so cute with that smile of hers. It makes everyone happy, including me.

"What's wrong, Ryobi-chan?" Ryona asks, snapping Ryobi out of her thoughts. "You look a little spaced out."

"Ah, no. I'm fine," Ryobi replies.

The older twin smirks and begins to rub her own breasts. "Ahhhh~! Were you admiring my chest here~?"

Ryobi blushes furiously at the sight of her sister getting closer to her. "Wh-why would I do that!?"

"Hehe~! Even though we're twins, you'll always be my baby sister~!"

"Stop calling me that! Just you wait until I have bigger boobs like you!"

"Baby sister~!" Ryona teases as she playfully scratches her sister's chin.

This makes the brunette finally snap. "I'm telling you, I'm NOT!" She pushes her sister down and gropes her large breasts hard. "Now I'm going to teach you a lesson that's even more painful than it was yesterday!"

"R-Ryobi-chan…ahhh…" Ryona moans. "Why do it here…Ah!"

"I don't care where we are as long as I'm doing this to you to get the message across!" Ryobi snarls.

The other girls at the locker room just stared at this awkward scene between the twins. Imu just leaves in disgust, not wanting to deal with this anymore while Murasaki quickly follows her. Miyabi just face palms herself for even watching the twins rough housing each other yet again.

Why do they always do this every day? she thinks to herself.

**Afternoon**

Ryobi and Ryona walk together out of school towards their dorms with the younger twin sighing.

"Are you okay, Ryobi-chan?" Ryona asks.

"I'm not okay…" the younger twin groans.

"Oh? What's the matter? Maybe I can help."

"No, thanks. I can handle it myself."

"Ah…okay…" Ryona is a little disappointed that her younger sister is not seeking help from her. But she lets it slide for now.

However, what Ryobi said to her was partly true. She is going to handle her problem herself, but she needed someone else to help her. Someone who's an expert on stuff like this.

**Murasaki's Room**

"God dang it!" Ryobi grunts as she clenches her fists while standing at Murasaki's door. "I can't believe I have to ask my nemesis for help. Even though it's really tempting to grope her huge breasts, that's not why I'm here." She takes a few deep breaths and raises her hand to knock on the door. "Murasaki? It's me, Ryobi! May I come in?"

No response. The younger twin knocks again.

"Murasaki?"

Still no response.

"What the heck is she doing in there?" She slightly opens the door and notices Murasaki watching some anime while eating some chips. And she's got some headphones on. "Maybe that's why she couldn't hear me." She goes over towards her and lightly taps her on the shoulder, making her jump in surprise.

"Ah! R-Ryobi-san!?" she cries as she takes one earbud off. "Wh-what are you doing here?"

The younger twin tries her very hardest to resist the urge to grope the quiet shut-in's large breasts, let alone look at them jiggling at every movement.

"I…I…um…n-need your h-help," Ryobi stutters at her words while her body is shaking uncontrollably. "I-I-I have someone I love and…um…I…uhhhh…don't know how to…say my true feelings…properly…" There is deep crimson red on her face when she says this.

Murasaki takes her other earbud off, staring at the brunette while having a cute, confused expression on her face. "Eh?"

"I need advice, okay!?" Ryobi shouts. "Is that too much to ask!?"

"Who…are you in love with?" Murasaki inquires.

"I-It's none of your business!" The brunette turns away to hide her blush and crosses her arms. "You either help me or I'll just find someone else!" For her, it's sort of difficult to consult with Miyabi or Imu since they are hard to talk to.

"Ryobi-san…" The violet haired girl says, quietly. "You're…in love with Ryona-san, right?"

Ryobi jumps at Murasaki's words. "Wh-what did you just say!?"

"I can tell…from the way you were blushing…" The quiet shut-in continues. "Don't try to fool me, Ryobi-san."

Curse this girl for watching so much anime! The sniper shouts mentally.

"Okay, you got me, happy now!?" She turns towards the violet haired girl with a blush still on her face. "I LOVE Ryona! I love her more than a sister, as my own girlfriend! We've always…we've always been with each other since the very beginning and that's when I began to have feelings for her. But I tried to hide them from her since I know that sisterly relationships are forbidden!" She clenches her fists while gritting her teeth. "That's why I'm not so sure if she'll accept my feelings!"

Murasaki stares at the younger twin with sympathy. She completely understands what Ryobi has been going through and how stressed she was about it. She gently takes her hand and leads her towards her computer.

"What are you doing?" Ryobi asks. "I don't have time to watch anime right now. I'm in a predicament here!"

"You need to watch this," Murasaki says. "Because I can show you that sisterly relationships can be acceptable and it's not such a bad thing." She turns towards the younger twin with a small smile. "I can help you, Ryobi-san. If you'd like, you can come over to my room to watch some of the episodes and read doujinshi each day to learn a thing or two."

Ryobi blushes. Is she…really going to teach me what sisterly relationships are all about? she thinks to herself. It's not like her to help someone in need when all she does is just sits secluded in her room all the day. But…this is what happens when you've got a cute otaku that knows some complicated relationships.

"Okay," Ryobi obliges. "Show me everything that I need to know."

Mursaki nods as she types in the anime and the two watch a show about two twins sisters that are in love with each other.

For the next 5 days, Ryobi has been coming over to Murasaki's room, watching "C*ndy B*y" and reading some doujinshi on sisterly relationships. And each day, Ryobi is learning anything and everything about it. And for her, she's happy that she's getting Murasaki's help. She's feeling more confident as the days went by.

However, Ryona, on the other hand, had been feeling lonely those past 5 days. Every day, Ryobi would tell her that she's going to be busy and then take off without another word. Ryona was curious to find out why she's not been walking with her every day, but on the 4th day, she did. She found Ryobi interacting with Murasaki and laughing with her. She wondered how long she had been enjoying her time with her, but she knew that Ryobi wouldn't answer her question even if she had asked her. It pained her heart to see her sister interacting with someone else. So, every day, she would walk home by herself, with no one to talk to.

After school that afternoon, Ryobi is walking down the halls to meet up with her older twin when she finds her leaning against the wall. The blonde's expression shows some sadness and sorrow for some reason. Ryobi slowly approaches her.

"Ryona?" she says. "What's the matter?"

The blonde bites her lip and looks down at the floor, clutching her books in her arms.

"Ryona, why do you look so sad? Did something happen?" The brunette walks a bit closer to her. "Come on, you can tell me-"

"Don't go!" Ryona cries.

Ryobi stops dead in her tracks. "Ryona…" Her expression softens at the sight of her older sister shedding tears.

"We've always been for each other…ever since we've been born," Ryona sobs. "We've always have been and never left each other's side! I…I love you, Ryobi-chan! I love you so much! B-but since you're going out with Murasaki-chan-"

"W-wait, hold it!" The brunette holds her hand up, signaling her to stop. "Who the hell says that I'm going out with her!?"

"I saw you two talking and laughing!" Ryona explains. "You were having a great time with her! That's why you've been avoiding me!"

Ryobi clenches her fists while gritting her teeth. "You…idiot…"

"Eh?"

"YOU IDIOT!" She pins Ryona against the wall, causing the blonde to drop her books in the process. She then quickly puts her lips against hers.

Ryona's heterochromatic eyes widen in shock from what her younger sister is doing, but the feeling of her lips touching hers relaxes her and immediately returns the kiss. Shortly after pulling away, Ryobi is now in tears.

"Y-you never…realized how stressed I was…" she sobs with angry tears streaming down her face. "You just freaking jumped to conclusions, Ryona! I was NEVER going out with Murasaki! The only reason I was with her was because I needed some help telling my true feelings towards you!"

"Ryobi-chan…" The blonde can only look at her and listen.

"I love you, Ryona!" The younger twin admits as she hugs her older sister tightly, burying her face in her chest. "I love you as my own girlfriend! I was so stressed and frustrated with myself lately because I was afraid…" She chokes a sob. "I was afraid you wouldn't accept my feelings. So-" Before she could finish, she feels Ryona tip her chin to her level and press her lips against hers. Ryobi returns the kiss shortly after and both of them pull away.

"Thank you, Ryobi-chan," Ryona says, softly. "I'm glad you told me your feelings."

"Ryona…do you…do you really think it will work out…for the two of us?" Ryobi asks.

The blonde hugs her younger sister closer to her and tenderly strokes her hair. "It will work out. I know it. Because you and I love each other more than anyone else in the world." She pulls Ryobi away and wipes the last of her tears with her thumb. "No matter who you are, you'll always be my little sister."

"Ryona…"

Realizing what she just said, the blonde softly bonks herself on the head while laughing nervously. "Oops. I said it again, didn't I? Ahahaha…" She's expecting the sniper to hit her, but instead, she feels arms wrap around her waist and head resting on her chest. She also notices a light blush on her sister's face. "Ryobi-chan?"

"Y-you know I love you, right?" the brunette stutters. "S-so..you can call me your 'little sis' anytime y-you want."

The older twin smiles and just kisses her on the forehead. "Will do…little sis~"

The twins hug each other soon after. This is just the beginning of a wonderful journey of their sisterly relationship.

A/N: I really do believe that Ryobi and Ryona deserve each other. I mean, who else would they pair up Ryona with? Hehe~! Also, I know Ryobi cusses, but I just put out some minor ones since she talks that way. I'm not into cussing at all, but I wanted to put those in there. Anyways, hope you all enjoyed the first chapter! Feel free to give out any suggestions, questions or concerns and don't forget to review~!
