“Do you want a shirt or something to wear?” Karin asked Sora as they entered her bedroom. After the talk in the hot tub, she was oddly excited to have Sora in her room, with neither of them wearing a stitch.

“No, I’m fine,” Sora replied with one of her adorable smiles.  Karin had always thought her sister was amazingly cute. When they had undressed earlier, she had found it hard not to stare and had only felt a little better when she saw Sora was having the same problem.

They crossed over to Karin’s bed and she politely pulled back the covers. Sora smiled and flicked her ear appreciably. Then she dropped her towel and crawled naked into the bed. Karin did the same and followed. The bed was large so there was plenty of space, yet when she got in, Karin moved in close to Sora and they turned to face each other under the covers.

“Do you think what Isana told us is weird?” Karin asked.

“I don’t know,” Sora shrugged. “I think she was right though.”


“Uh-huh,” Sora smiled again. “I like looking at you naked, just like she said and I get all warm and tingly from it. I liked looking at her and Ayaka naked too. You’re all nice to look at and it feels good.”

“Well, I like looking at you too,” Karin admitted. “A lot actually. I meant it when I said you were cute. But I meant the other stuff. Isana sounded like it would be perfectly okay to want and have sex with you, her and Ayaka.”

“That is what she said,” Sora answered with a confused frown. “Why? I think it all sounded nice.”

“How do you know so much about sex anyway?” Karin frowned back. “I’m older than you, but you seem to know a lot.”

Sora blushed furiously, but she answered. “Marta liked to play with girls. One of the older girls came in sometimes and they would do stuff under the blankets. I never got to see much, but I knew that they were doing stuff. My other roommate, Crystal, touched herself in the open a lot too.”

“Wow, I had no idea,” Karin said, staring in amazement. “You never did anything?”

“No way!” Sora exclaimed, blushing to the tips of her long ears. “They were mean to me all the time and I would have been too nervous anyways.”

“But not here?” Karin asked, curious.

“I’m still nervous,” Sora admitted. “But I like you guys a lot.  You are always nice and you don’t treat me weird. And I trust Isana.”

“I really like her too,” Ayaka grinned. “She’s like a cool aunt or older sister. Though Ayaka feels a little like that too, at least to me.” Karin frowned then. “Where’d she go? To her room?”

“She went to Isana’s room,” Sora answered, with a smile. “After she said goodnight in the hall she hurried that way. I think she wants to be with Isana tonight. They were touching a lot in the tub.”

“They were?”

“Yeah, their hands were moving and I could see them touching under the water.”

Karin thought about that for a moment, “Do you think Ayaka is really over there having sex with Isana?”

“It looked like they both wanted to,” Sora said, shrugging again. This time the sheet slipped and exposed her naked chest. Karin’s eyes dropped and stared at the two hard, tiny nipples. When her eyes came back up, Sora looked pleased.

“You really don’t think it’s weird that I like looking at you so much?” Karin asked again.

“No,” Sora answered simply. She pulled on the sheet and Karin’s chest also became exposed. Sora reached out a small, curious hand and gently gave one of Karin’s much thicker nipples a pinch. Karin frowned at how good it felt but didn’t stop her. After a moment Sora pulled her hand away with a wider smile of pleasure.

Karin rolled her eyes, feeling amused now instead of worried. If there was no point in fighting it, she may as well enjoy it. So she reached out her hands and pulled Sora to her and then pulled the sheets back over both of them. When she saw how happy Sora was by her acceptance, Karin felt very warm and happy herself.

It felt really nice having Sora’s hot, naked skin against her own, and she could feel it when either of their nipples rubbed somewhere. One hand found its way to Sora’s rounded butt and it felt good there. “Okay,” she admitted. “This is actually very nice.”

“Hmmm, thank you, Karin,” Sora smiled at her from just inches away. Then Sora surprised her with a quick peck on the lips. Sora flushed again, and then she nuzzled her face down near Karin’s neck to hide it. “Thank you.”

“It’s all right,” Karin said, feeling hot from the brief kiss. “You’re my sister now, Sora, and I like you a lot. The kiss was nice. Can I have another one?”

Sora’s face came back into view and this time Karin kissed her. It was very brief and soft, but they found it immeasurably enjoyable. When they separated Sora settled her head on the pillow with a pleased sigh. Karin smiled affectionately.

“Sora, let’s just go to sleep like this, okay?” Sora nodded her more than willing acceptance and closed her eyes. “Goodnight.”

“Night, Karin,” Sora replied in a happy, dreamy tone.

Sora’s breathing evened out into a contented sleep and Karin decided to hell with being weird. She liked looking at her new sister and her kisses with Sora had felt awesome. It also felt nice to have Sora in her arms. Isana had told them earlier that this was only a beginning and she was looking forward to whatever else would come. Even the thought of having sex wasn’t really scary anymore. Instead she wondered if Sora would be willing to be her first.

But that could wait for now. So she laid her face down next to Sora’s, careful not to poke her with the curve of her horn, and went to sleep.


The soft, muffled sound of water rushing through pipes awoke Karin to a new day, but it was a cool, teasing breeze coming in through her open window and the warm place in the bed next to her that truly got her mind moving. She was still lying on her side and had one hand where another person had been only moments before. There was a sense of loss too, because of the person that was missing. She heard the door to the bathroom behind her click open and rolled over quickly, searching.

“Sora?!” Karin said excitedly, her eyes alighting upon the tantalizingly nude form of her new younger sister. Sora stopped in surprise at the call with one small hand upon the door jamb and her long, expressive ears flicked twice in question as her almond-shaped eyes locked onto Karin.

For a long, hushed moment, they sat still like that, watching each other. Karin for her part thankfully drank in Sora all over again, as if it was the first time.  Now that she knew the truth of what she’d been feeling inside lately, it was as if the knowledge had set part of her free, a part that was just now poking its head above ground. Seeing Sora again, after having spent the night cuddled together in the same bed, made her heart beat faster with the anticipation of… something.

Sora was so stunning to look at. It was this thought that was predominant in her thinking for many minutes.  Sure, Sora looked very young in every way, just like she herself did, but Karin very much enjoyed what she was seeing. She loved her sister’s long, midnight-dark hair and her smooth tan-colored skin that looked soft, smooth and touchable. She vaguely remembered the feel of it against her from last night and ached for it again.  She watched a slight flush suffuse Sora’s skin as the younger girl stood under her gaze; it went all the way up to her fascinating ears.

“Karin!” Sora exclaimed in her sweet voice, her ears drooping slightly in embarrassment. “You’re staring at me!”

“Hee hee,” Karin smiled and quickly slid to the edge of the bed and cast off the warm sheets as she swung her legs down and sat up straight, exposing herself. The same breeze that had been teasing her cheeks before caressed her whole body now and she felt her long, thick nipples hardening a little at the sudden temperature change, as well as for other obvious reasons. “I can’t really say I’m sorry, Sora. I like looking at you this way, because you’re so cute!”

“Oooh!” Sora moaned low, and her blushing increased dramatically. Her brown eyes though were solidly on Karin’s own nude form. Karin did nothing to impede her sister’s gaze. She wanted Sora to see her too.

Karin stood up, unable to be still any longer because her body was filled with an excited, sexual energy that was still very new and raw.  She crossed over the shag rug to Sora, until they were only a single step apart. She wasn’t much taller than her sister, so their eyes found each other with ease. Karin was still smiling warmly and she saw some of Sora’s reflexive shyness dissipating from her expression, which made her even prettier. Karin raised a hand slowly to the top of Sora’s small head and gently ran her fingers into and down the silky-smooth, black hair. They both shivered.

“Your hair feels so smooth and nice,” Karin observed aloud in wonder. It was like she was discovering Sora all over again and it was horribly exhilarating. She could feel something between her legs, like it was hot inside. Her heart was beating like a drum and she could imagine something like an electric tingle from her exploring fingers. Sora very seemed pleased at first by her compliment, but there was still a hint of stubborn discontentment in her eyes. “Did I say something wrong?”

“I don’t want to be cute.” Sora complained, even as she moved her head to aid Karin’s stroking. “It makes me sound like a little kid.”

“We’re both still kids!” Karin laughed easily. She leaned in on pure impulse and gave Sora a quick, but soft, peck on her tiny lips. Sora blinked, jerked her face back and gasped at her in surprise. Karin grinned even as her brain thrummed from the touch of their lips. “So what if you’re cute? I think you’re beautiful too, and pretty and adorable and totally huggable! It makes me want to hold you tight and touch you all day long!”

Following her own words, Karin reached out with her free hand, held Sora by her bare hip, and pulled her in close. Their unclothed bellies pressed together and they both let out simultaneous gasps from the warm skin-to-skin contact. Karin finished by wrapping that arm around Sora’s back, while the other one ran a finger lightly down Sora’s left ear. Sora squeaked and the ear twitched crazily for a second.

“Sorry, did that hurt you?” Karin asked, looking into her sister’s face intently.

“No!” Sora said quickly, relaxing very willingly into Karin’s hold with a smile in return. Karin loved it. She almost couldn’t believe what she was experiencing. “It felt good, but it kind of tickled a little… maybe. It was a nice tickle, though.”

“What if I do this instead?” Karin darted her face forward and quickly licked with her very long tongue down the top of the same ear.

“Karin!” Sora’s face reddened and she wriggled in Karin’s arms, which felt oddly good for both of them. “You licked me!”

“It looks like you liked it, though,” Karin laughed, greatly enjoying what they were doing. Sora felt so wonderful to hold onto, just like she had in bed during the night.

“Hmm, maybe, but it was kinda weird too,” Sora moaned, but her smile soon returned again. “This feels nice, though. You’re really warm, Karin. Your arms feel good too.”

“Yeah, it totally does feel awesome,” Karin agreed wholeheartedly. “Did you like sleeping with me too? Did you sleep okay?”

“Uh-hmm,” Sora affirmed quickly with a happy nod. Her shyness was almost completely gone now. “Sleeping with people feels really good. I liked doing it with you and Isana. Do you think Ayaka had a good night too?”

“Oh, sure!” The reminder that her new older sister had gone to have real, actual sex with Isana made her whole body tingle again. It also made her even more aware of Sora’s nakedness against her own body. “She’s with Isana, so she probably had a nice time. They were getting along really well, right?”

“She looked so excited last night,” Sora giggled pleasantly. Karin felt something on the outside of her thigh and a quick shiver went through her when she realized that it was Sora’s small hand. “Isana was touching her like this under the water and she seemed to like it a whole lot.”

“Well, it does feel kinda good,” Karin agreed, aware of every movement of that hand. Sora giggled at the comment again so Karin felt a little bold. “Come back to bed with me!”

She pulled back and grabbed Sora’s hand in one motion and before Sora had a chance to say a thing, Karin dragged her back towards her bed. Once her shock dissolved, Sora laughed happily and willingly allowed herself to be towed along. At the bed, Karin maneuvered Sora by her bare shoulders so that the back of her knees were against the edge of the bed and gently started to push her backwards. Sora got the idea quickly and fell back with a playful giggle, her arms spread, and then scooted back on her butt so she was all the way on.

Karin stared again for a moment at her naked sister, enjoying the sight immensely, and then climbed over her, straddling Sora at the waist. When she bent forward so that they were looking in each other’s eyes again, she saw pleasure and joy on her sister’s face at what was clearly happening.  Softly, Karin reached down with a hand and stroked over a cheek with skin the color of a warm wood. It was smooth and soft and she felt her own cheeks blush when Sora made a soft cooing sound and cuddled her face into the hand. It was a sound that made her whole being excited.

“Is it okay that I’m touching you?” Karin asked a little belatedly. She didn’t want her own excitement to cause Sora any kind of harm or to scare her. It was immensely important to her that Sora enjoyed everything.

“It feels nice, and I really like it,” Sora smiled with total trust in her expression. “I can touch you too, right?”

“Of course!” Karin replied immediately, lightly bumping her nose to Sora’s, which made the other girl giggle some more, which in turn made Karin feel hot all over again.  She rose back up, and one of Sora’s slim arms followed so that they were both touching the other’s face. Sora’s fingers were tiny, but she was gentle and her stroking felt right and very affectionate.

For the next little while, they played a kind of game in a very amiable silence that needed no words. Karin ran her hand along one of Sora’s skinny arms, feeling her smooth skin and a little warm sweat. Sora repeated the action on her own body, with skin-tingling results. Then Karin made Sora laugh when she felt over her tummy and around her cutely small belly button. Karin really wanted to lick it. Again Sora followed her lead and she could feel the heat between her legs turn into a tingly, humid hotness. They ran their hands over almost every inch of exposed skin on their upper bodies except for their breasts. When Sora knew they were next, her face slipped from joyful wonderment to slight concern.

“I don’t have anything there,” Sora complained in a soft, breathy voice when she saw Karin looking at her chest curiously.

“What are these then?” Karin replied with a friendly, sisterly laugh, running her hands up Sora’s stomach again to her almost-flat chest and circled each nipple with her middle fingers. Sora twitched and gasped at the sudden contact and Karin smiled wide as she felt rubbery flesh grow firmer at her touching. She kept tweaking at them and marveled at how such a simple thing could make Sora feel as good as her facial expressions suggested. When she stopped, she dropped her arms, deliberately inviting Sora to reciprocate.

“That was really nice,” Sora said with a happy sigh, her voice wispy. She was breathing a little harder and her skin looked flushed in a different way now that was exciting Karin. Sora slowly raised her arms and cupped her hands over Karin’s tiny breasts. “You have real boobs. I like them.”

“I have bumps,” Karin chuckled, really liking how it felt to have someone else touch her chest, especially a girl as special as Sora was fast becoming to her. She had discovered masturbation just over a year ago, after catching another, older girl at it in the bathroom one day, and she’d always liked tugging and playing with her long nipples, but Sora’s hands felt a hundred times better. She also liked that Sora seemed to like touching her a whole lot too. Sora’s happiness made her happy. “Ayaka’s the only one of us that has anything like real ones. Hers are probably bigger than Isana’s.”

“D’you think she’d let us touch them?” Sora asked with an amused smile, groping away happily at Karin. Then she giggled playfully and gave the big buds under her hands light pinches. Karin shivered hard at the surprise rush of pleasure that passed through her body and had to stop from arching herself. Her nipples had never felt that good before. It was like they’d been zapped.

“Do that again!” Karin gasped.

“Pinching them?” Sora asked, with a happy smile of accomplishment on her face. “It feels good?”

“Yeah!” Karin answered with a definite nod. “It makes me really tingle.”

“Hmmm,” this time Sora pinched both at the same time and when her fingers twisted a little as she applied pressure, Karin felt even better than the last time.

“Wow Sora,” Karin said in amazement, staring down at her adorable sister. She’d never have thought her breasts could feel so good. Wanting to see if Sora would like it too, Karin reached down with one hand and gave Sora’s left nipple a pinch.

“Ooh!” Sora’s eyes opened wide.

“See?” Karin laughed. “It’s a lot better when someone else does it.”

“I feel really good,” Sora said, her smile proclaiming how good a time she was having. Then she frowned again in confusion. “Karin, why is there something hot and wet on my legs?”

At first Karin was confused too and looked down. She rose up a little for light and saw that her still hairless lower lips were incredibly wet and slightly open from her excitement. Below her, right under where her crotch had been, was a wet spot on Sora’s thigh. She saw it all and smiled at Sora as desire bloomed in her mind again. “It’s from me, and maybe you a little too, Sora. Did you have sex-ed in school yet?”

“No, that’s next year,” Sora replied warily, but obviously curious. “It’s from that place?”

“Yeah!” Karin laughed, and saw a funny expression forming on her sister’s face that made her laugh harder. “It’s not gross at all, and it’s not pee. Haven’t you ever played with yourself down there?”

Sora’s face became less happy again. “I wanted to try it because my roommates did it a lot, but not with them there. I never really had time alone. Somebody was always around and I was too scared to try it in the showers. Is it nice?”

“Oh yeah, totally,” Karin answered emphatically with a nod. She leaned in close again so their faces were only inches apart. Sora even smelled good. “If you ever want to do it now that we live here, and you will want to, go right ahead and do it. If you ever want some time alone, you tell me and I’ll go. If you want to play with your puss, none of us will make fun of you, because I know Ayaka does it, and there’s no way Isana went years without doing it either. So relax and smile again, I like that a lot better.” She finished with a soft kiss to the tip of Sora’s nose.

“Okay, I will,” Sora laughed, her smile returning. “So what’s the wet stuff?”

“Wellll… girls make some kind of slippery liquid from the sex and baby hole, the vagina I think, to make it easier for a penis to slide inside,” Karin informed her, making a vague thrusting gesture with a hand and finger in the air that Sora laughed very hard at. “I don’t remember what it’s called exactly, but that’s not important anyways. It comes out of girls when we are excited and want to do sex stuff. It means we’re horny!” They both laughed at that. “It felt really good when you were touching me, so of course I got wet.”

Sora seemed content with the answer and Karin felt kind of proud at being able to be the older, informed sister. Then Sora’s expression became even more excited and Karin’s heart beat a little faster in an instinctive response. Sora’s face came up towards hers and Karin felt surprise and then a heady rush of pure pleasure as small, warm lips touched onto hers again in a real kiss.

“I really like kissing you,” Sora explained softly, her cheeks reddening under Karin’s wondering eyes. “It feels special.”

In response, Karin rested herself more fully onto Sora, and they both moaned deeply as she kissed Sora back and held her tightly.  This time it was a much longer kiss; a real kiss containing all their new emotions. They were both inexperienced, so it was a bit clumsy at first, but neither of them would have had it any other way in that moment. Instead their eyes slowly closed and they kissed again, and again, learning from each other’s lips.  Karin loved the soft, electric feel of the act and her brain buzzed from both her own pleasure and Sora’s.  The fact that she made Sora feel good enough to moan almost nonstop made it a thousand times more exciting.

As they slowly explored each other’s lips, the kisses grew deeper and more passionate and lovingly intimate. Both of them lost their last traces of shyness around each other and just enjoyed the physical act of loving the girl in their arms.  When Karin parted her lips at one point, Sora did the same and for the first time, their tongues touched and slid together.  Karin felt a quiver run through Sora that was echoed within her own body and then their lips separated and their lidded eyes carried deep emotions for a few minutes of stillness. Karin saw the seeds of real love for the first time in her young life and it made her mind buzz.

“Kissing is so nice,” Sora commented eventually, affectionate eyes shining in open wonder. She was also breathing a bit harder. “Thank you, Karin.”

Karin snorted a soft laugh and smiled anew, hugging Sora a little tighter. “See, you don’t have to thank me, because I enjoyed that just as much as you did. We did it together. But I think I’m going to be kissing you a lot from now on if it’s like that! So be warned!”

“Okay!” Sora agreed, playfully giving Karin another quick kiss. “Me too!”

Karin became distinctly aware again of the hot wetness between her legs that had apparently quadrupled from Sora kissing her. It felt messy. She really wanted to do something about that now, but something else entered the fore of her mind in relation. She wanted to see all of Sora, especially the special places.

Slowly, so as not to alarm Sora too much, Karin started to slide down her sister, back towards the edge of the bed. Sora watched on curiously and Karin felt warm inside at the trust being given to her.  She wanted to make Sora feel really good and at the same time, learn more about her while keeping that faith. When she was kneeling between Sora’s spread legs, Karin bent forward and down again towards the ‘v’ of her goal.

As her face drew closer, she heard Sora’s breathing increase greatly, but she said nothing in objection and actually rose up on her elbows to watch. Karin though was focused. She stopped with her face a foot away from Sora’s young pussy.

“It’s so pretty, Sora,” Karin said in undiluted awe. This was the first time she’d ever actually had a good, close look at what was between a girl’s legs. She’d never even looked at her own very well, but resolved to fix that soon. Sora’s flower was nestled between her smooth thighs and below a very pronounced pubic mound that was devoid of any hair.  There was a pair of puffy outer lips with bright pink wetness peeking from her slit in between.  At the top, Karin could make out Sora’s cute little bump.

“You think it’s pretty down there?” Sora asked.

“Yeah!” Karin affirmed, breathing in a scent of female muskiness. It kind of made her thirsty. “It even smells pretty!”

“Karin! Don’t smell me!” Sora complained, reflexively trying to close her legs. Karin’s head became trapped in a quite wonderful place, nose almost smushed right into Sora’s sex. She breathed in deeply again, and because she liked the smell so much, she pushed forward the last bit and used her nose to rub side-to-side over the little bump Karin knew felt good to touch.

“Oh!” Sora’s legs popped back open and Karin looked up to see Sora staring down at her in astonishment. “What was that?!”

“It’s your bumpy spot, your clit,” Karin answered with a pleased grin. She pulled back just a smidge, aware that her nose was wet now, and raised her right hand to tap her index finger lightly on the indicated spot. Sora twitched. “It gets really sensitive and feels good to touch, right?”

“Yeah,” Sora replied. “Is your nose wet from me?”

“Ah-hmm,” Karin nodded happily. She ran her finger down the soft lips of Sora’s puss and felt her own tingle at the action. They felt slippery, soft and hot. When her digit was coated in a wet sheen, she thrust it up towards Sora’s face. “See? That’s from you, and it smells good.”

Sora used her own hands to hold Karin’s still and sniffed experimentally. “It’s not awful,” Sora said with relief and ran her fingers over Karin’s. “It really is slippery though.”

“Yep, but let me show you what this place is good for now,” Karin said, pulling her hand back. She laid it gently over Sora’s entire vaginal area and rubbed over it. Sora’s lower lips were engorged and very aroused and Karin’s actions produced small gasps of wondrous pleasure from the young girl.  Then Karin slowly used her fingers to tenderly spread Sora’s open and they both gasped, if for different reasons.

“The sex-ed lady was right, it’s like a beautiful pink flower,” Karin said in amazement, feeling totally electrified by the sight of Sora’s most intimate place.  There was also a feeling of awe that Sora was doing this with her and trusted her to make it feel good. She could see everything; including the tight looking hole that was leaking juices. A sharp intake of breath when her thumb stroked down one of the lips from Sora reminded Karin that she was here to please now, not to play tourist on her sister’s cute body.

Deciding to imitate on Sora what she liked to do when she masturbated, Karin started to rub with a pair of fingers up and down the lips and the tender, pink insides. It soon got even wetter down there because Karin paid very close attention to Sora’s face, learning which places made her gasp or otherwise respond in sexual delight. It was also kind of neat to see the expressions Sora made. Karin’s hands got so slippery eventually that her finger accidentally slipped deep inside Sora’s very tight hole and they both jolted in surprise as vaginal muscles squeezed the invader.

“Karin!” Sora exclaimed loudly and sharply. Her eyes were wide open and her breathing sounded ragged. Sweat made her skin glisten. “I can feel your finger in me! It’s inside!”

“Did I hurt you?” Karin asked quickly, feeling hot, wet muscles squeezing hard onto her finger in pulses.

“Uhm…” Sora seemed too confused and aroused to talk and she shivered hard all over. Then, in concern for her sister, Karin tried to pull her finger out, but it dragged over Sora’s erect clit on the way and the younger girl went rigged while gasping for air. Karin felt a hot liquid pouring onto her hand. She raised it hurriedly in panic, and then realized Sora had just had a powerful orgasm. So good that Sora kind of just laid there for a bit,  not moving.

“Are you okay?” Karin asked.

“Karin…”Sora’s voice was wistful and soft as she lay dreamily on the bed. “I feel so good.”

Karin let out a relieved sigh that stopped cold when she saw her hand. A pinkish-redness was in the wet stuff coating the finger she’d accidentally put inside Sora. She’d taken Sora’s virginity.  She didn’t know if that was good or bad. Would Sora hate her for it?

“What’s wrong?”

Karin looked back up and saw that Sora was giving her a glorious smile and her face looked radiant in its sweaty messiness. She looked like she’d just experienced the most wonderful thing ever.  Karin couldn’t lie to Sora about this though, so she raised the hand. “I broke your hymen.”

Sora stared at her for a moment, still looking happy, but confused by Karin’s concern. “Is that bad?” she asked. “Aren’t you supposed to let someone you love do that? I saw that in movies and stuff.”

“Yeah!” Karin replied, feeling worried.

“Then… it’s okay,” Sora said, as if it was totally obvious. For a moment, all Karin felt was confusion, then Sora’s face brightened in realization of this and she giggled. Then she sat up rapidly and flung her arms around Karin where she once again found small lips pressed to hers.

The kiss was amazingly intense. Karin had never seen Sora so determined, but she could feel her little sister’s fierce emotions through the act and her heart was thundering in response. After almost five minutes of being thoroughly kissed and kissing back, Karin pulled away.

“You’re not angry with me then?” Karin asked slowly, keenly feeling her own arousal burning away.

“Why?” Sora laughed. “It kinda hurt and felt good at the same time, but I was already feeling so good that when you pulled your finger out, I went boom!”


“My… uh, puss…” Sora scrunched her face over an appropriate term for her sex, “When it exploded and made me shake and feel shivery good. But that doesn’t matter.”

“It doesn’t?”

“No!” Sora beamed and her ears were quivering as her cheeks reddened. “You’re my sister, and I love you, so it’s okay.”

“You love me already?” Karin felt her cheeks heating and she also felt a renewed desire to kiss her sister, but she held back for now.

“Mmm-hmm,” Sora giggled, and snuggled close again. At first Karin didn’t get why Sora turn her head as she did so, but then she realized what Sora actually wanted and let out a laugh of her own and then licked at her sister’s long ear. Sora’s pleased giggling redoubled. “It feels so nice.”

“Now you know what an orgasm feels like,” Karin said, enjoying the closeness.

“Did we have sex?” Sora asked excitedly, jerking her head back to look Karin in the face while beaming happily.

“Uhm, kind of, I think,” Karin answered slowly, unsure. “I had sex with you at least, because I made you come.”

Sora’s almond eyes widened and she looked suddenly intent. “Can I do it to you now?” Karin could tell this meant a lot to Sora, because there was a hint of vulnerability in her expression. “Then it has to count, right?”

“Do you want me to lie back like you were?” Karin asked instead, more than happy to let Sora do almost anything she wanted.

“Yes!” Sora became animated again with her ears twitching wildly with her excitement. Karin let herself be turned and pushed onto her back. She spread her legs and almost laughed at how eagerly Sora squirmed down between them.  Wanting to be able to see at least a little, Karin dragged over a couple pillows and propped her head up as Sora got herself into place, imitating what Karin had done to her. Karin found it quite exciting to see her sister’s face looking between her legs so attentively.

“It’s all drippy wet,” Sora said with her most cheerful giggle. She looked up and Karin saw laughter in her brown eyes. Sora was certainly enjoying herself.  Then the eyes went back to work and Karin jumped when she felt a finger press rather firmly onto her very sensitive clit. “Your bumpy thing is kinda big, and it’s hard and squishy at the same time.”

Karin didn’t know where Sora got the idea, but as with her nipples, the girl gave her tender organ a solid pinch and Karin felt like she almost wet herself; it felt so odd and wonderful at the same time. Sora seemed fascinated by her clit and Karin’s mind went a little blank from the sensations of small fingers exploring her slit while her bud was relentlessly attacked. She could feel herself being opened up, but it was a detached sensation, buried in with all the pleasure.  She did notice however, when Sora’s finger slipped inside her pussy and filled her.

“Ow!” Karin couldn’t help the painful exclamation of Sora finding her own virginal barrier. Sora paused and looked up at her with such a look of hopeful love that Karin nodded her acceptance immediately and without fear. She would give to Sora what Sora had given to her. “Go ahead.”

Sora smiled joyously and Karin felt her mind weaken again as the fingering of her pussy resumed with gusto.  Sora seemed to know that breaking Karin’s hymen would be more painful than her own experience and she slowly worked that finger in and out of her wet entrance. When Sora finally plunged it all the way in, the pain was sharp and distinct, but Sora gave her no respite to dwell on it. Instead her finger thrust inside vigorously, driving her body onward.

“Sora…” Karin whispered, clawing her hands into the bed-sheets. Her sister’s finger was pressing very firmly on the inner wall of her vagina as it invaded, and she felt something like a strong need to pee, even as she felt her orgasm rising like an agitated snake. The tension grew and grew, seemingly without end, even as that odd pressure increased in an almost painful parallel.  Finally her body could hold on no more. “Oh… God! Sora!”

The orgasm was like a wonderful, most pleasurable punch to the gut and head. Her body curled reflexively and she felt the pressure in her groin release all at once.  Sora yelped loudly in shock about something, but for several minutes Karin was captive to her body’s need to reset back to sanity. When she did settle back down, breathing hard as if she’d run a mile, she found that she was being hugged very tight by Sora, who was smiling proudly.

“Now we really had sex!” the younger girl laughed. There was not one sign at all that she regretted anything.

“I’d say so!” Karin agreed and then noticed something. “Sora, why is your chest and neck all wet?”

“Your juice stuff squirted out on me,” Sora said with her now ubiquitous giggle, that Karin was fast learning to love. “I thought it was pee at first, but it doesn’t smell like pee at all.”

“Sorry,” Karin said, laughing as well. She felt so much better now than playing with herself ever did. She wrapped her own arms around Sora and returned the embrace. Rolling them over so that she was on top again, Karin gave Sora a long, deep kiss. More kissing naturally followed until they both lay still, feeling oddly content.

“I love living here,” Karin said after a long while of companionable silence filled only by the birdsong from outside and Sora’s soft breathing. They’d shifted onto their sides a little so that Sora could nuzzle her face in by Karin’s neck. “I have a new kind-of-mom, my own room, a cool older sister, and an awesome little sister.”

“I love you too,” Sora replied, a pleased tone warming her voice. “Can we do this again?”

“Of course we can,” Karin said immediately, stroking one of Sora’s ears and drawing out a soft coo. “I loved every minute of it. You can also sleep with me whenever you want. But remember about Ayaka. I like her too, and Isana.”

“I know!” Sora giggled. “I want to try touching Ayaka too; she’s really nice for an older sister. Do you think she’ll want to?”

“She said last night that she was okay with things, but we probably shouldn’t be pushy,” Karin mused. “But I love her too, Sora. She gives wonderful hugs. Plus, I know Isana would love it if we wanted to do things with her. She sounded so happy that we didn’t freak out last night.”

“She feels nice too,” Sora agreed. “She grabbed my butt when we were in bed and I think she liked it.”

Karin frowned, and then moved her arms so that she could grope Sora’s butt properly. Sora gave a pleased giggle at the act and wiggled her behind encouragingly. “Your butt is pretty nice, Sora,” Karin told her, smiling. “It’s so round and soft.”

“And it feels good,” Sora smiled back and rubbed herself against Karin. When Sora’s smooth belly pressed over her mound, Karin felt a new pressure that was gaining strength and grimaced at the interruption.

“That was a weird face,” Sora informed her unnecessarily.

“Yeah, I know, but I have to pee really badly,” Karin admitted.

“Oh!” Sora responded with another laugh and an amused wiggle of her ears. “But I don’t want to let go. This feels too nice.”

“Sora!” Karin moaned, feeling Sora wriggle herself. “I really am going to pee on you if I don’t go now.”

“Eeww,” Sora laughed, sliding back jokingly on the bed and letting Karin free.

“Yeah, eeww,” Karin agreed as she crawled around Sora and quickly darted into her bathroom and towards her toilet under the small bathroom window. When she seated herself, she saw Sora had followed her inside and was watching her pee with open curiosity. “Are you watching me?”

“I’ve never seen another girl pee before,” Sora said, inquisitive eyes locked on Karin’s crotch. “It kinda looks funny this way.”

When Karin was done, feeling a little pleasantly sore from their activities, and also a little bemused by her sister’s odd interest in her bodily functions, her eyes flicked over her huge bath and an idea for later flickered into life. But there was also a rumble in her belly for food. Grinning, she snatched Sora’s hand and yanked her sister into her lap with a yelp.

“Okay, then,” Karin said once Sora was straddling her with an expression that said she very much liked being in that position. “What do you want first, food or a bath?”

“Hmmm,” Sora mused over the question for a moment and then smiled with a chagrined look. “Breakfast. I’m really hungry.”

“Food it is, then!” Karin agreed, unable to decide if she was disappointed or not because her own stomach seemed to agree with Sora. She got them standing again and they walked back into the bedroom. Karin gestured towards the pile on the floor containing Sora’s towel and her clothes from the previous night. “Do you want to go and grab some fresh clothes and meet me back here?”

“Sure!” Sora quickly wrapped herself in the towel to hide her nudity and held her dirty clothes in her arms. At the door, she turned and they shared one more lingering series of kisses before she giggled and bounced out for her room.

Karin felt a moment of mystified loss when Sora was gone, but it only lasted a moment. She’d see her again soon enough and she also wanted to see Ayaka and Isana.  But she didn’t want to interrupt her older sister, so she set her own dirty clothes aside with a mental note to ask about a hamper of some sort. Then she dug through her bag and pulled on a pair of plain pink panties, cut-off jean shorts and a loose, white tank-top shirt. Once done, she started loading the rest of her few belongings into her dresser as she awaited Sora’s return.

On to Chapter Six!

    Whoever keeps rating/voting this story “1 heart/awful”, and i suspect it is the same person each time, just stop reading it!! It’s evidently not your ‘type’ of erotic story, and not going to “improve” to your Standards, so just DON’T READ IT!!
    Or, at least have the decency to comment as to WHY you think it rates so low a score 😠
    (Rant over!!! Just narks me when people do that!!)

      I’ve long suspected that we have one regular who gives a rock-bottom rating to any story that isn’t a wham-bam-thank-you-ma’am exercise. My advice is to let it slide… and I say that as an author who has received his share of those onesie stars.

      So sad when this happens, people take time to create and share only to have others shoot them down, then the ones that do the bitching complain because their are no new stories or the site shuts down, folk are not going to contribute to put up with crap and to me it is like tv if you don’t like what is there turn it off , same here if you don’t like a story don’t read it, i think it is that these folk know they can’t create something worth reading so they have to put others down, i only wish i had the ability to create stories worth reading

    I agree Kacey, if he or she doesn’t like it then don’t read the stories and go to some other site! I think it was an amazing chapter, well written and detailed. Sisters exploring each other and making love is so erotic. Well done Nuit du Loup, I can’t wait to read the next chapter.
