The council had many secret rooms, but Riri noticed she was following Kira to her dorm. She wasn't a hundred percent sure of her intentions before, especially after that warning in the hunt, but it seems Kira needs her attention today. As always in these times, Kira is the one to open and hold the door for her to enter. Riri slowly bows to her sister before entering, winning only a jaw tightening from her sister.

Despite some setbacks, the day has ended in a way Kira could see as a victory, having Yumeko lose the hunt and watching her face as she noticed that someone she thought was a friend, put up a bet against her. But maybe that isn't enough. Maybe she really wanted to shoot Yumeko at that moment. And Riri had stopped her, she didn't want to see blood in her sisters hands, hers was bloody enough for both of them.

Riri lets her gaze fall to the floor as she waits for her sister to enter the room and lock the door.

Kira moved to her mirror, snapping her fingers to get her sister's attention. When she sees Riri eyes on her she opens her arms and waits for her to get the cue. Riri promptly moved to remove Kira jacket, when she turned to take it to the bed her sister said: "Leave it." Turning to face her with no further explanation, so Riri figured she was asking her to drop it on the ground.

Riri knows what is expected of her, but for some reason she always hesitates to initiate it, probably knowing it is the moment where the 'no turning back' motion sets. She let the jacket fall to the ground, feeling her finger tremble as they move for the buttons of Kira's shirt, feeling her sister watchful gaze on her hands movements.

Riri likes that her sister lets her undress on her own time, it eases her mind into what they're about to do.

Kira moves her arms back a little, letting her sister take her shirt off of her, feeling the cold air of the room touch her warm skin. She shivers a little under her sister's ministrations, feeling Riri move her arms around her body to undo her bra, letting it fall around her arms until it hits the ground. She sucks in a deep breath as she watches her sister undo her skirt. – She never understood why Riri never questioned what they were doing, always accepting of what Kira asked of her. – Riri follows the falling skirt with her hands, burying her fingers in her sister's stockings and pulling it down close to Kira heels, stopping to take them before fully removing the stockings.

After having Kira fully undressed, she wasn't allowed to touch her with her hands anymore.

She moved to hold her hand on her back, looking up to her sister with patient eyes.

Kira slowly went to hold her little sister's face, looking for anything in her eyes, but as always, she didn't found nothing. She buried her fingers in the strings of Riri's mask, slowly removing it from her face, watching as she licks her lips as soon as the mask falls onto the ground. Kira straightened, opening her legs only enough for Riri to bury her face in between them.

And that's what she did.

Riri could hear a soft breath coming from her sister when she went to smell her. – Her smell was soft compared to his, lingering in a satisfying way instead of overbearing. – Her clit twitched with the attention, anxious for more – but Kira never moved her hand to push her head –. Riri's tongue came out to explore her sister's core, feeling the well known taste fall into her mouth. She watched as Kira stopped looking down at her to look at nothing in particular on her room, her fingers twitching at her sides.

Riri often wondered what made Kira come to her for the first time. Did he say something to her? Riri didn't know, but she knew how to help and wanted to be there for her sister outside of her rule on St Dominic students.

Her tongue moved along Kira folds, pumping into her pussy for a while before coming to suck softly on her clit, knowing how sensitive it was, not wanting to hurt the girl above her in any way. She started feeling Kira hips coming to meet her tongue, feeling her bud grinding against my nose as she went back to her hole, making Riri let a muffled moan under her.

"Riri..." She said in a pleading voice, giving some steps back to support herself on the mirror as Riri follows her while still kneeling. Kira moves one of her legs over her shoulder as Riri supports herself with her hands on the floor, pushing herself further into her hot and welcoming cunt. While watching from the corner of her eyes the way Kira was scratching the mirror glass, Riri wondered if it would be possible for it to break under their body pressure.

She doesn't think Kira cares about it at the moment.

Riri noticed the blue eyed girl on top of her start to waver over her, trembling while she moans her name repeatedly. Riri watched her sister break above her, shivering as she cums in her mouth. "God, Riri-! How- Do you-" Kira squirmed as her sister continues to lick her sensitive core "Do this so damn well..." She says in one breath, moving to get her leg off of Riri's shoulder, signaling her to stop.

She doesn't answer. She never do.

Riri watched as her sister went to the bed, waiting for her cue to follow. When her sister signaled for her to come she quickly got up, feeling her legs wobble a little from numbness of staying in the kneeling position for too long. Kira was seated, waiting patiently for her. As she got closer she noticed her sister searching her face, looking for something Riri didn't understand. She must not have found it as Riri stood there, waiting for her next order.

Kira's jaw tensed again, deciding to focus on her sister clothes. "Undress for me." She said and went to her bedside to pick something.

Riri did what was asked of her, not without shuddering under her sister's room pressure. It was less than that room, but the strange feeling of being closed in from all sides was still there. She knows what came now, Kira wants to see her breaking under her, even if it only by a little. It seems like nothing that Riri does is enough to soothe Kira's doubts on where her loyalty lies, so she has to make sure that Riri knows her place. – And maybe something else, but Kira wasn't ready to think that yet. – Kira picked a strap-on that she always makes sure it's ready, it was the only one she used now, having gone through 2 bigger ones that she noticed brought pain to her sister. Even if she never said nothing, hiding her pain in Kira's shoulder, pretending her whines and tears were from pleasure, Kira noticed.

Kira didn't like thinking why her sister never said anything, but she also never asked. – She couldn't show that she cared enough to notice; the subtle changes in her expressions, the way her cries became smaller but higher pitched as they went on...

She thought this one still was too big for her, as Riri still showed signs of pain and discomfort, even if only at the beginning now. – Riri was never wet enough during intercourse, so she thinks that may be the cause or one of them. – She never bothered buying lube before though. But, some of the teacher had catched some students fucking in the library and other unfrequented places. After that, they got together to make a sex education class one day, giving some condoms, lube bottles and other things Kira don't care enough to remember. Suki and Rex were a little embarrassed, so she could think of some of the ways the teacher thought it was important to give away lube.

Although to Kira, it was obvious Rex likes it raw.

While Riri was still occupied with her clothes, Kira made sure to spread some of the lube on the strap, letting out a tsk with how noticeable it was she used it, praying Riri won't talk about it. When she turned Riri was already getting on the bed, silently laying in Kira's soft pillow, looking at the roof with unfocused eyes. Kira followed her into the bed, settling between her legs, feeling her around her folds. Riri shivers involuntarily, feeling her sister slowly testing her entrance with her fingers, caring not to hurt her with her nails..

Kira noticed that she was a little more wet today than normal, making her wonder why. What happened differently today? – Kira prefers not to linger on memories regarding Mary and Riri together.

She finally hovers over her sister, watching her gaze fall from the roof to her cold blue eyes. Riri seems to be accessing something in her, if she finds it or not, she doesn't show. Kira sometimes wants to ask her things, or only say something, but she never does, and it seems like talking becomes increasingly harder every time.

There's nothing to be discussed, Kira is showing her power and Riri is accepting her place under her...

Riri watches as Kira struggles with something in her mind, guiding her strap to her dripping hole. She prepares herself for the pain, working on her breath as she feels it pressing against her entrance. She appreciates how slow she enters, always pulling it out before going further again, stretching her walls in an attentive and satisfying way. – Riri noticed the lube, the change in size and the way Kira is always watching her reactions. She appreciates it, but it doesn't matter, it always hurts. – Still, her sister made sure it wasn't too bad.

She always wanted to be like him, never understanding she is the opposite.

Kira was always feeling, he never truly felt anything.

Riri let out a low whimper, griping the sheets, turning her face to the side as her sister moved her face down, licking her face, bringing her body to grind against Riri as she moved, kissing and biting the unprotected neck. She wants to suck it, but Kira can't risk leaving visible marks on her sister's pale skin. She couldn't hold a moan of her own, feeling her breast pressing down on Riri's. Kira licked back up to her lips, kissing it hungrily, saying between kisses: "You can touch me, Riri."

That was everything Riri needed, letting go of the sheets to hold her sister's face, deepening the kiss and swallowing Kira moans as she enters her mouth with her tongue. Kira doesn't fight for dominance in the kiss, letting Riri guide their tongues dance as she focuses on her thrusts. Sometimes Riri would let out pain whimpers against her mouth, but she didn't let Kira get away from the kiss. The girl on top had to pay close attention to when the whimpers would come, making sure her movements only brought pleasure to the younger girl. Eventually, moans of pleasure would leave Riri, making it harder for her to keep the kiss going, giving Kira the opportunity to move into a better position.

Moving to sit on her heel, she gripped her sister's hips, moving while watching Riri reactions, noticing the way the girl arm went to lay over her eyes. Her free hand went to hold one of Kira's, making her turn it to hold hers as she moved the free one to bring her leg over her shoulders, changing the position again. Riri let out a groan, moving the hand of the arm on her eyes to grip the pillow, gazing the girl on top of her. The way Kira's mouth is open, the way she nibbles and kisses her calves, the way she holds her hand tightly, like she was afraid Riri would let go of it.

He would never do anything that could be deemed as soft, always leaving as quickly as he comes, his hands always leaving purple marks against Riri's thin skin.

But for once, Riri felt her father's memories leaving her mind as quickly as it entered, permitting her to focus on the pleasure she was feeling.

"Kira, please..." Riri watched her sister's eyes widening, her thrusts faltering as she heard Riri's voice above the slap of skins. She nodded, whispering in a low tone:

"I like how you look under me, pleading to cum like this..." Riri whimpered, letting go of the pillow to go and touch her hardened clit. If Kira eyes could widen more of surprise it would have fallen from her eyes socket. "What is with you today? Did the hunt affect you in a way you don't want to tell me?" Riri wished she could tell how much these moments meant to her. His way of celebrating a well done job was painful to her... since then, she has been waiting for her sister's reassuring ways, even if for Kira, this meant something different. "I have been noticing your little talks with Mary, has she been touching you?" The question was degrading, but she noticed the way Kira's movements slowed, waiting for her answer.

"I could never choose someone else to see me like this." Riri says, stopping her hands movements, using her strength to turn them over, watching as Kira tries to fight to get up. As her strap pulls from inside her, Riri moves to sit on her abdomen, pushing her own hands against Kira's chest until she stops wiggling against the bed. Her chest moves up and down as she takes heavy breaths under her, with a faint blush against her otherwise composed face.

"What are you doing?!" She asked in a hushed tone, thrusting her hips up instinctively. Riri didn't answer, letting go of Kira's chest to move her body up the bed, peering down as realization settles on her sister's face. A slow gulp is heard under her. "That's not your place to be, Riri." Despite saying that, she didn't move to stop her.

Riri waited for a moment, checking if her sister would make any movement against her. When she doesn't, the younger girl finally lets her weight down on her sister's face, sighing in delight when she finally felt Kira's tongue coming to explore her folds. Riri could feel her sister gaze on her face, studying her. She didn't look down anymore, focusing on holding herself up with the headboard, with her eyes closed in concentration.

Kira was satisfied with what she found this time, moving her hands to hold her hips with an unexpected strength, lessening Riri's ability to move around. She seemed more than eager to lose herself in her sister's heat, not caring if her makeup was getting messy. She was licking and sucking her dry, making the girl on top spasm on top of her from time to time.

Her suction was rough, but Riri was pleased to find out she actually liked it.

She moves her hands from the headboard, gripping Kira's hair with some force, humping furiously against her mouth. The roughness of it ripped a throaty moan from Kira, making her instinctively grip Riri's thighs with a matching force, dipping her nails against her flesh.

Riri couldn't give a damn about the pain on her thighs, too focused on her own pleasure to pay attention to the suffocating girl in-between her legs. She could hear the loud sounds coming from the bed banging against the wall, wondering if there was any possibility that someone would pass through the hall of Kira's dorm.

The feeling was too much, when she couldn't hold her orgasm anymore, her thighs squeezed shut around Kira's head, making her face look comical and hot at the same time. The way her eyes were watery, blurring her mascara and having it run down her checks with the stand alone tears that have fallen. The way her brows were furrowed together while she looked up at her. The disheveled way her hair was laying against the pillow. Everything about her made Riri's body tremble on top of her, throwing her head back and letting out a soft moan as she felt the sensation of release wash over her.

She let out a content sigh, looking down again and finally freeing her sister from her thighs murderer hold, watching as a strand of cum connect Kira's mouth to her pussy. The other girl takes in deep breaths, coughing while trying to come back from almost passing out. When she finally settled down, she looked up at her with hungry eyes.

Riri expected anger for her actions, not... That look.

Kira moved her hands to her hips, pushing her down on her body, making Rice sit on her lap. She uses her abs strength to push herself up, using one of her hands to pull Riri into a deep kiss. Riri couldn't hold back a moan when she felt her own taste in Kira's mouth.

"I want you to ride me. Will you?" Is all she says before moving her head down to suck on Riri's nipples.

Riri agreed in an almost imperceptible whisper, holding Kira against her chest as she moved up from her lap, using one hand to support herself on Kira's shoulder and the other to guide her strap to her entrance. She didn't wait before lowering herself down on it, moaning against her sister's hair.

Kira let out her nipples with a pop, "That's it, you are being so responsive today..." Her sister's hands came to hold Riri's hips, helping her move against her lap. "You look so beautiful when you don't hide your emotions." She said, looking up at the girl riding her. Her words fall heavy on Riri's mind, making her eyes tear up slightly. Riri drops her head against her sister's, holding their forehead together as she nods.

If she said it, then it's true.

"You will always be by my side, won't you?" Riri whimpered, nodding again, murmuring a million yesses as she plastered kisses against her sister's face. It wins her a moan and a tug on her hair as Kira pulls her to another kiss, this time not letting go of her until she cums again, moving her free hand from her hips to her eager clit.

Riri moans against the kiss, feeling her orgasm rise again, biting her sister's lower lips strong enough to draw blood, ripping a whimper from the older girl. She could breath again, meaning she could focus on quickening her pace against Kira's lap. She bites her own lips as she looks down at her sister, watching the way her blue eyes follow hers, how her lips were red and open, with a deep blush running her face and ears. Riri caught herself repeating "I love you" multiple times to Kira, moving to whisper into her ears, noticing how her movements on her clit faltered slightly, before returning faster and more concise. Kira held her face against her neck, kissing and nibbling at Riri's.

"I love you too, Riri." Was all she needed to start convulsing on top of her, moaning loudly against Kira's neck as she cums on top of her.

-

It took a while for them to move.

They stayed in that position for a while after she came, with her sister strap still inside of her.

Kira hands caressed her back, sometimes scratching softly with her nails.

"You did well today."

Riri only nodded, wondering if she will hear Kira profess her love for her more often after today.

Sisterly or not.
