"Go ahead."

Most people, whether boys or girls, eventually happen across the situation where they become intimate for the first time. With a husband, or a girlfriend… or even a casual acquaintance for some people. The circumstances didn't really matter in the long run. The point is that most people found themselves in the same exact situation at some point in their lives.

Some people, when they get married.

Others before that if they so choose.

And others still, tragic that it was, that didn't really have a choice in the matter.

Some, like Yumi found herself in that exact moment, when they were eighteen years old and found themselves in an empty room after school hours with their best friend, their acting practice having been handily discontinued by a few not-so-innocent kisses, and they find themselves asking "Is this the right time? Do I really want to do this? Here… now? Is this worth it? What would my family, my friends think when and if they find out? What will become of our relationship after this moment, if we choose to continue?"

"Will this ruin everything between us?"

All valid concerns to an eighteen year old girl.

But as Yumi Fukuzawa sat there in her chair, completely naked save for her panties, shoes and socks, with her Petite Soeur Touko Matsudaira leaning over her, the tips of her long, slender fingers ghosting inside the top of her underwear, she could safely say that none of these concerns occurred to her.

She knew Touko. She trusted Touko. She loved her— as a sister. As a friend. As… a girlfriend?

Before now she had never given the thought much attention. But now that she knew Touko was interested… and not just interested, but actively wanted her… Well, now she certainly has my attention.

They could work with that.

So, in a word, yes. Yumi was definitely ready.

She just needed to make Touko fully aware of that fact.

"Touko." She whispered, or tried to at least. Her voice sounded strained and shaky with excitement. Ignoring that, she reached out to snatch the younger girl's hand with her own. Touko blinked rapidly, her blush brighter than Yumi could ever remember seeing it.

"Y-yes, Onee-sama?" She replied, her tone as nervous as Yumi ever heard. It was nice to know Yumi wasn't alone in that regard. Though, it was interesting to see Touko's previous bravado and aggressiveness suddenly and inexplicably absent. Apparently, when she got right down to it, Touko was a typical seventeen year old girl, with all the inexperience that implied. How she had managed to seem so in-control up to this point was just a testament to her acting skills, and no small amount of determination, Yumi guessed.

Typical Touko.

But Yumi was just as determined, now. She knew what Touko wanted, and was pleased to know that she wanted it as well. She would just have to take the lead this time.

She was supposed to be the Grande Soeur here, in any case. It was only right.

"Have you ever…?" Yumi prompted, just to know where things stood as far as Touko's knowledge went. She was pretty sure the younger girl hadn't, but Touko could have had a boyfriend – girlfriend? – before and therefore knew the mechanics.

Rose Cinensis en Bouton shook her head, her jaw clenched tightly.

"Not even," Yumi hesitated, her heart hammering in her chest. "by yourself?" At Touko's suddenly indignant look, Yumi rolled her eyes. "Of come on, I think we're past that point, Touko. Just tell me."

Swallowing, Touko's eyes narrowed slightly. "Of course I have, Onee-sama." She responded, blushing mightily, though her voice lacked the hardness she was known for. She obviously knew the older girl was just trying to be helpful to the situation at hand.

"Then it's the same thing." Yumi said, running her fingers along the top of Touko's hand. "Please, Touko—" She shifted her hips on her chair, trying to find a more comfortable position. Her arousal made it more than slightly difficult to sit still, and she was getting restless. "I really want you." She admitted, blushing heavily as she heard the words hang in the air around them. The phrase sounded good in her head; she only wish it hadn't sounded so… dirty out loud.

Her words seemed to trigger something in Touko's eyes. Her eyebrows narrowed, and her lips thinned. Her hands, both the one resting atop Yumi's light blue panties and the one on her upper leg, clenched slightly, causing the older girl to stiffen and let out a sharp sigh.

"You do?" Touko asked, her voice a mere whisper.

Yumi nodded, shifting again and rubbing her thighs together. "Yes. Please, Touko, I want to feel you—" She licked her lips, suddenly feeling really embarrassed as she thought about what she wanted Touko to do. "Inside me."

Oh, Maria-sama… when did I become so… naughty?

Yumi shut her eyes, took a deep breath, and released it. It didn't help the almost painful feeling of arousal that throbbed from within. If anything, is made it worse. She opened her eyes to find Touko staring back at her, her mouth slightly ajar in shock. Obviously, she hadn't expected Rosa Chinensis to be so blunt about what she wanted.

Feeling her cheeks flush even more, Yumi narrowed her eyes at her Soeur. "I won't tell you again, Touko." She snapped, her arousal winning out over her patience. She shifted her hips on her seat, relishing in the feeling of friction she felt on the bottom of her thighs "I want you inside me. Now."

Touko blinked a few more times, as if processing this information, and then swallowed. "Okay." She simply said, licking her lips. Yumi whimpered and nodded frantically, her proprietary all but gone, and leaned back in her seat, intent on giving Touko as much ease of access as she could.

"Please." Yumi repeated, rubbing her thighs together and her chest heaving. "I can't wait anymore."

Touko nodded and learned her head toward Yumi. Rosa Chinensis did not wait, however. She reached out with her free hand to grab at the front of Touko's uniform, pulling the girl forward and all but clashing their mouths together in a heated kiss. Yumi didn't hesitate to slip her tongue into Touko's mouth, and groaned when their two tongues met to continue their previous melee.

Her other hand, which had been caressing Touko's resting on her underwear, apparently had enough of being nice. With a non-subtle push, she took Touko's hand and slid in underneath the elastic of her panties, groaning when she felt the girl's fingers curl in the soft hair underneath.

"Touko." She breathed, breaking away from Touko's mouth to release in a deep, shuddering sigh. "Touch me. Please."

Touko whimpered in agreement, pressing her face up against Yumi's front and nodding. Yumi craned her head to the side so she could witness what Touko was doing, half in curiosity and the other half in sheer want. She wanted to see Touko touch her. She wanted to know that this wasn't a dream, that this was actually happening, and that Touko was with her, spiraling down together in their feeling of lust, excitement, and joy.

Yumi could see the outlines of Touko's fingers through her panties as they worked, moving and caressing her with slow, methodical movements. Her fingers were imprecise and off-center, clearly due to the younger girl's standing position and not knowing exactly where to please her Soeur best, but Yumi wasn't being particularly picky at the moment. Just the knowledge that Touko was there, trying to make Yumi feel good, was enough to send jolts of pleasure through her, causing her to whimper and fidget in delight.

"Touko… ahn—" Yumi heard herself breath out heavily. She hissed when Touko hit a particular sensitive point, and she lurched slightly.

"Onee-sama." Touko responded, reaching up with her free hand to palm one of Yumi's breasts. The older girl arched her back into Touko's grasp, sighing appreciatively at the added sensation.

"It f-feels good, Touko." Yumi whispered harshly, watching as the younger girl worked her fingers underneath her panties. "So good. Faster." She urged.

Touko responded by nodding, her face flush up against the soft skin of Yumi's breast. The younger girl whimpered aloud as she sped her fingers up, pressing and rubbing with abandon. When she hit a particularly sensitive point, Yumi jolted and clasped Touko's hand tightly against her, as if she was clutching a prized possession close to her.

"Ah! There!" Yumi mewled, leaning her head back and breathing harshly. "Go there – faster!"

Not bothering to reply vocally, Touko pressed against the spot Yumi forced her hand against and moved her fingers frantically, moaning when Yumi reached around with her free hand to tug at her hair. It must have hurt the girl, Yumi realized, but with so many sensations and feelings rushing through her, and Touko right there responding to everything along with her, Yumi couldn't bring herself to be any more gentle.

Touko's fingers slipped further down, finding their way into Yumi's warm, slick crevice, and her palm joined in the action by pressing up against the sensitive point her fingers had just been working on. The sudden friction of Touko's hand, along with her fingers sliding along between her thighs, was too much.

With a sharp cry, Yumi jerked underneath Touko. Her toes curled in her shoes. Her legs crossed and her thighs pressed together. Her hands, one gripping Touko's hair and the other helping the younger girl's hand between her legs, spasmed frantically. Her spine arched, her chest pushing out towards Touko. She wanted to shut her eyes, to concentrate on the sudden, and powerful, climax that assaulted every part of her body.

But she wanted to watch Touko more. She wanted to see her Soeur, and what she was doing to her to make Yumi feel this way. She wanted to show Touko her face when she shuddered and jerked underneath her. She wanted Touko to know that she was doing this to Yumi as she bucked her hips into her hand.

Touko stared up into Yumi's face, her eyes wide and a dark pink blush covering her cheeks. Her hand had faltered when Yumi had cried out, but hadn't stopped. She had slowed her ministrations, allowing Yumi to come down from the sensation comfortably; which the older girl was grateful for. It had been powerful, and intense, and she was breathing frantically as her hips rolled against Touko's hand, trying her best to ride out what she could of the orgasm Touko had given to her.

It had felt… fantastic.

"Touko…" She murmured, pulling the girls head back up to hers and pressed their lips together in a kiss. Touko responded immediately, catching Yumi off guard a little. She felt Touko's tongue slip inside her lips and seek out her own, a sharp whine slipping past the younger girl's lips when she succeeded.

Touko's hand, the one that had been attached to her breast, reached up to grab the back of Yumi's head, matching her Grande Soeur in her previous action of tugging on her hair, though not as painfully as Yumi thought she had.

"Onee-sama." Touko whispered breathily. She leaned forward and settling herself on Yumi's lap, pulling her hand out of Yumi's panties to wrap it around her torso, settling on grasping at her back. When Yumi felt Touko's neatly trimmed nails dig into the skin above her hip, and felt Touko rock her hips on Yumi's thigh, did she realize what Touko wanted.

Determined to do right by Touko – after all, Yumi had been more that satisfied in return – Yumi made to push Touko up so the younger girl could take her place on the chair.

Instead, Touko surprised Yumi by shaking her head, pressing her face into the skin between her neck and shoulder, inhaling deeply as she rocked her hips.

"No," She whispered into Yumi's ear, causing a shiver to creep deliciously up her spine. "I want to come like this. Help me." Not wanting to disappoint her Petite Soeur, Yumi only nodded in response, reaching around with one hand to grip the back of Touko's uniform with one hand, and reaching down into the bottom of her skirt with the other.

It was a difficult process, to work her hand through Touko's bunched up skirt to the junction between her thighs. But Yumi was determined to do anything she could to assist Touko with her much-deserved orgasm. She pushed her hand through Touko's skirt, sliding her fingers up her hips, to the top of Touko's panties.

The girl's desperate whimper in her ear gave her all the permission she needed.

Yumi fought against Touko's grinding to force her underwear aside, so that her fingers had as much access as possible. Touko didn't stop, or even slow, in her movements, but gave a pleasant hum in response to the added friction of Yumi's fingers to her center.

She moved against Yumi, gasping and sighing against the older girl's neck, with increasing frequency as she rocked her hips against Rose Chinensis.

"Onee-sama," She whispered into Yumi's ear after a few moments. "Put – ah! Put… finger inside…" She moved against Yumi with an increasingly steady rhythm, but took a moment's respite to raise herself off of Yumi's leg to give her access. "Please, I need you inside me."

Yumi nodded repeatedly, her smile brittle as glass as she was quickly overwhelmed with emotion. Touko wants me! She really wants me! She needs me to make her feel good, just like I did. Just the thought alone was enough to make her want to cry.

At Touko's incessant whine, Yumi nudged the girl's dark green panties aside and pressed her hand up against her, earning a shudder from the girl on top of her.

"Onee-sama-!" Touko whined, her tone pleading as she moved her hips roughly against the older girl's hand. "Please."

Nodding again, Yumi maneuvered her way into Touko's slipping a finger deep inside her. She was rewarded with sharp whimper, and the feeling of Touko's nails digging into her back.

"I want you inside me, too." Yumi said, reaching her free hand away from behind Touko's head and down to her underwear, desperately trying to pull it down off her hips. Touko seemed to understand, even as her eyes were clouded and her whimpers came tumbling from her lips. She brought her hand from Yumi's back, leaving her other hand clutching Yumi's hair, and helped in tugging Yumi's panties down to her knees in two quick movements. There was little ceremony in Touko slipping her right ring finger into Yumi's wetness, causing a long, high-pitched whine to break free from her throat.

Yumi took a moment to acclimatize to the feeling of Touko's finger inside of her, before nodded to the other girl. Touko took that as permission to start moving, slowly at first, as Yumi was doing to her, but quickly increasing the rhythm at which she worked.

Yumi matched Touko, but at a slightly faster pace at the younger girl's urging. Her free hand reached around to grasp at Touko's thigh, groping and digging her nails into the soft flesh there for lack of anything else within reach. She felt Touko grip and tug at her hair, and while not painful, it was enough to distract her from climaxing again too quickly.

Touko groaned and whimpered, moving frantically against Yumi's hand as she worked, increasing her speed along with the older girl. It seemed as though the two of them were in sync, their hands determined not to fall behind as their whines and sighs joined in.

Eventually, Yumi felt her muscles start to contract, and she knew she was about to finish. She bit back a cry and clutched hard at Touko's uniform. "T-Touko—I'm—!"

The younger girl nodded, whimpered desperately. "I know, Onee-sama. Me too!"

Touko writhed above Yumi, shuddering violently but somehow managed to keep from moving out of her embrace. The girl gripped at her hair just shy of painfully, and pressed her face into her neck, her muffled cry vibrating through Yumi as she felt Touko tense above her. Touko's finger curled inside her, giving Yumi the final edge she needed for her own orgasm, and she jerked underneath Touko, whimpering as her body tensed deliriously in the wake of what Touko had done to her.

The two girls sat there, in each other's embrace, breathing heavily for a few long moments, before finally gathering up the energy to extricate themselves from each other. Yumi winced slightly as Touko pulled her hand free from between her thighs, and was pleased to find that there was no lingering pain from what they had done.

In fact, she felt wonderful.

Touko stood up and stepped away from Yumi, reaching up to wrap her arms around her body protectively. Her face was bright red either from exertion or embarrassment— Yumi didn't know.

Suddenly, with a tell-tale chill up her spine, Yumi realized that she was naked, except for her shoes, socks, and underwear hanging between her knees. Blushing furiously, she scrambled to pull up her panties, and mumbled a word of thanks as Touko handed over her discarded skirt, uniform shirt and tie, which Yumi donned silently.

Once dressed, Yumi stood, stretching her arms above her head and sighed as her joints creaked. She lowered her arms, and turned towards Touko. The younger girl still hadn't moved from her spot, leaning against the table, her arms wrapped around her torse.

Yumi blinked, and stepped up to face the younger girl. After a few seconds, Touko started and looked up into Yumi's face, her cheeks pink with… embarrassment? Shame? Yumi wasn't quite sure, but she knew just what to say to break the awkwardness.

She cleared her throat. "So, uh…" She began, a nervous smile blossoming on her face. "I guess that means I lost?"

Touko blinked slowly, as if catching up to Yumi's train of thought, and then the light of understanding dawned in her eyes. All at once the unsure, embarrassed girl melted away. In its place was the sure, determined, somewhat aloof Touko Matsudaira – Rosa Chinensis En Bouton.

She smirked and nodded haughtily at Yumi's admission. "Yes, it certainly seems so, Onee-sama." She said, her tone cool and confident. "If you cannot go a full hour as a doll, then you simply are not ready for the play. We… may even need to increase out practice sessions." She finished, biting her lip and watching her Grande Soeur through her eyelashes.

Yumi nodded indulgingly. "I guess so." She sighed, chagrined. "Maybe we should get together and practice this weekend?"

Touko's eyes flashed, as if picking up some hidden meaning behind Yumi's words. She seemed to consider her Soeur for a moment, her finger tapping on her upper lip in thought. "Yes, I would have to agree. I could offer you my home for our practice, if you like, Onee-sama." She looked away, suddenly bashful. "Of course, you don't have to, if you don't—"

Yumi cut the younger girl off by reaching out with her hand and placing in on Touko's shoulder. The girl blinked, looking back towards Yumi. She opened her mouth to respond, only to have Yumi interrupt her by pressing her lips soundly against Touko's in a firm kiss.

"That sounds great." Yumi finally said after pulling away, almost laughing at the shell-shocked expression on Touko's face. "It's a date."

Touko blinked three times, shook her head, and slowly smiled.

"Of course, Onee-sama."
