================

The dim twilight clung to the desolate tatami mats of the Tachibana family dojo. Anri moved through her forms alone, a shadow of her former self. The vigorous energy she once possessed was gone, replaced by mechanical movements, her eyes empty as she faced an illusory enemy.

"Anri-san," my voice, soft yet echoing, broke the stillness of the dojo.

Her body tensed, her movements abruptly ceasing.

"Sato-kun..." she turned, surprise filling her eyes. "I heard you were hospitalized. You challenged Katagiri and got seriously injured, didn't you?"

Without a direct answer, I began to explain. "I... have a special ability," I chose my words carefully. "It's called psychometry".

"Psychometry?" she echoed.

"When I touch an object, I can see its memories," I continued, "And recently... I can also erase people's memories".

Anri's expression shifted, a mix of understanding and fear creeping in. "Earlier, when I visited you in the hospital, your smartphone was in the living room. I saw memories from that smartphone". I consciously avoided mentioning the karaoke box investigation, knowing her smartphone also held those memories.

Anri's face drained of color. "Then..." her voice trembled, "Me and Kokoro... what kind of days we spent with Katagiri..."

"Yes," I nodded quietly. "I saw everything".

The spring breeze rustled the dojo's shoji screens, the only sound breaking the heavy silence.

"You... saw everything, didn't you?" Anri's voice trembled slightly. The long shadows of our figures stretched across the dojo's tatami. The spring twilight bathed the heavy air in an orange hue.

"Yes," my voice was as quiet as possible. "Even what happened in the karaoke room".

Anri's body trembled slightly. "And the date in the one-piece dress". I carefully continued, "What happened on the train, and at the movie theater". "I saw everything". The last words hung heavily in the dojo. A single tear escaped Anri's eye. She hastily wiped it away with the sleeve of her white dojo uniform.

"I didn't want to believe it," I continued. "But I couldn't forgive Katagiri for it". The wind creaked the dojo's shoji, as if foretelling the truth I was about to reveal. "I tried to get the video back... and that's why I challenged Katagiri".

Anri's eyes widened in surprise. "No..."

"His power is incredible. His paralysis ability. He almost killed me". I chuckled, a self-deprecating sound. "Furthermore, Katagiri's karate skills were real. I was hospitalized for a while. But it seems I awakened from near death". I continued, "The ability to erase memories was dormant within me".

"That..." Anri's voice was hoarse.

"Yes. I erased the memories of everyone involved with Anri-san and Kokoro-chan, one by one". "First, Yamaoka. His memory of being excited watching your video". "Then Teramoto and Tanaka. The memories of the two who participated in the orgy at the karaoke".

Anri's body sagged, but no tears fell yet. "And finally... Katagiri. All of his memories. Even the power of the paralysis earrings he received from Hyakko. From that practice match to today, no one anymore..." my voice softened. "No one remembers that incident. No one except me, Anri-san, and Kokoro-chan".

At that moment, Anri's dam broke. Large tears soaked the tatami. "I'm... the worst, aren't I?" her voice trembled. "I couldn't resist until it came to this. I've fallen lower than an animal. Defecating on playground equipment in a park, doing that with my anus... not even animals do that!" She continued to wipe away tears with the sleeve of her white dojo uniform, but they showed no sign of stopping.

"If both of you wish," I began quietly, "I can erase your memories".

Anri's eyes briefly gleamed with hope, then clouded in deep thought. "Then..." Anri's voice trembled, "Erase Kokoro's memories". Deep sisterly love resonated in those words. "Those memories..." the words that followed were laced with pain, "are too heavy for her".

"Yes," I nodded quietly. "Anri-san...?"

As I questioned her, the air in the dojo seemed to still for a moment. Anri spoke after a long silence. "I... won't erase these memories". Her voice held a strong resolve.

"If I erase them, then your life-threatening act of saving me will also disappear, won't it?"

"Yes," my answer was short but certain.

"Then don't erase them," Anri's voice echoed in the twilight dojo. There was no longer any hesitation in her eyes. Wiping away her last tears with the sleeve of her white dojo uniform, she quietly continued, "I will live carrying these memories". Her words held strong resolve and deep self-reproach.

"I will engrave in my heart that I had such a side to myself".

Long shadows stretched across the dojo's tatami. "You must despise me, don't you?" Anri's voice suddenly turned bitter. "Me". Before I could answer, she continued, "You saw everything, didn't you? In the end, I was shaking my hips myself..." Her voice was filled with limitless self-loathing.

"I'm the worst, aren't I?" Anri bowed deeply. It was the pitiful repentance of a girl who was once a proud karateka.

"You know," Anri's voice trembled slightly, "At that time, I felt something inside me breaking". Her fingers, tightly gripping the tatami, turned white. "But I couldn't stop it. I succumbed to my weakness, to pleasure. And by the time I realized it..." Her words trailed off.

A heavy silence fell in the dojo. "That's why these memories are necessary," Anri looked up. New strength resided in her eyes. "To never again show such weakness. My memories as a sister who couldn't protect Kokoro, and as a karateka who discarded her pride. That is my atonement". Anri's voice echoed quietly but surely. "By not forgetting, by continuing to bear them..."

I silently watched her, firmly accepting the weight of her resolve.

"And I want you, who saved us, to remember". Anri's voice trembled as it echoed. The sleeve of her white dojo uniform wiped away tears again. How many times had it been tonight? "That sight of me". Each word was heavy. "As a sister, as a girl, as a human, I absolutely never want anyone to see it". Anri's voice grew even softer.

"I want you to remember that sight". That wish contained repentance, a prayer, and a sound as if seeking salvation.

"You're the worst, aren't you?" My voice echoed coldly in the dojo.

Anri's body trembled slightly, but she didn't look away.

"You defecated an enormous amount of thick poop, then you yourself shook your hips in the multi-purpose toilet and climaxed repeatedly during anal sex... you were like a beast". Each word was like a blade. "No, you were worse than a beast. You were covered in snot and drool, making a terrible face". Anri's fingers clenched tightly on the tatami. The collar of her white dojo uniform became wet with tears.

"In front of people, like that, even after that, when I was erasing their memories, I saw various memories that I couldn't retrieve from their smartphones during my hospitalization. Three-hole orgy in the karaoke box. Exposure date in the park at night. S&M training at the love hotel. You cried and screamed, but in the end, you succumbed to pleasure, made vulgar demands yourself, and then climaxed repeatedly until you passed out from frenzy". Anri's face turned pale instantly. Still, I continued, "Without any self-control". My voice grew even colder.

"You eventually went to them yourself, taking Kokoro-chan with you".

A heavy silence fell in the dojo. Only the smoke from an incense stick rose quietly. "You're the worst. You're truly a vulgar and dirty person, aren't you?" the final blow. "I respected you so much. The dignified and cool Anri-san is gone".

At that moment, all the strength drained from Anri's body. Her white dojo uniform crumbled onto the tatami like a broken flower. Anri remained deeply bowed, no longer even shedding tears. The darkness enveloping the dojo deepened its silence.

"But," my voice softened slightly, "I accept everything".

Anri's trembling back moved slightly, then stopped. "I destroyed Katagiri's smartphone". I stated the facts one by one. "So, Katagiri doesn't have that footage either". A brief silence, and then, "However," my voice began to tremble again, "I have to tell you something honestly".

The darkness in the dojo deepened even further. "My ability..." I chose my words carefully, "can also save the memories I see as videos on my smartphone". Anri's body tensed. "Anri-san and Kokoro-chan's... those images... are on my smartphone". The sound of rain hitting the shoji. Unbeknownst to us, spring night rain had begun to fall.

"And," the last confession was squeezed from my throat, "While I hated Katagiri, I also... envied him". Anri's back trembled greatly. "I, too," my voice was hoarse, "am a terrible person". Anri's moist eyes looked at me.

"Since that day... I've watched the videos many times. Even though I knew I shouldn't. Even though I knew it would trample on Anri-san and Kokoro-chan's hearts". My body felt heavy with guilt. "I tried to stop. But... every time I saw Anri-san and Kokoro-chan's crazy climaxing faces, I... masturbated and ejaculated many times myself". My words caught in my throat. My hands clenched tightly, gripping the tatami.

"Your usual dignified expression, your serious gaze during practice, your occasional gentle smiles. And... those vulgar and lewd images in the video". I exhaled deeply. "All of it is burned into my mind... and won't disappear".

"Sato-kun..."

"Even now... I look at Anri-san with vulgar sexual feelings. Even if I try to hide it, I can't erase it. I think, 'Ah, such a beautiful and cute person can get so messed up'". I stood up and walked to the window. The setting sun stretched my shadow long.

"Just as Anri-san became disheveled and indulged in pleasure, I also have weak and dirty parts. But I think that's what it means to be human". I turned around and faced Anri. "There's no such thing as a perfect human. Not me, not Anri-san, not Kokoro-chan".

"I..."

"It's okay to have weaknesses. It's okay to be lost. Sometimes, you might even pretend to be someone you're not". I took a step forward. "All of Anri-san... I think it's wonderful". My words echoed heavily in the dojo.

"Your strong-willed parts, your weak parts, your sometimes childish expressions, even your lewd and vulgar parts. Including all of that, Anri-san as a person is wonderful".

"But I... I'm already soiled..."

"No, you're not," my strong voice interrupted Anri's words. "Everyone has darkness. Everyone has light. And living while embracing all of it is what it means to be human". I knelt on the tatami, meeting Anri's gaze. "So... shall we walk together?" My outstretched hand was illuminated by the setting sun.

"While accepting all of our weaknesses and strengths".

New tears fell from Anri's eyes, but they were of a different color.

"Sato-kun..." her voice trembled, but a faint hope was mixed within it.

"From now on... together..."

"Sato-kun..."

"Sometimes strong, sometimes weak. But all of that is Anri-san".

"I... actually..." Anri's voice trembled slightly, "I didn't hate myself at that time".

"I understand".

"Really?"

"Yes. Because, in my memories, Anri-san's face, in the end, was happy". Tears welled up in Anri's eyes at my words. "It's okay not to be perfect. Sometimes complaining, sometimes showing an embarrassing side. I think that's true strength".

"Sato-kun... thank you".

The twilight dojo. The last rays of light from the window cast long shadows on the tatami mats.

"Sato-kun..." Anri's voice was smaller than usual.

"Yes?"

"That..." Her words trailed off. Her usual dignified expression held a hint of childishness.

"What is it?"

"Sato-kun's... lap, can I sit on it?" My heart skipped a beat at the unexpected words.

"Eh?"

"It's hard..." Anri's voice trembled. "I've been strong all this time. In front of everyone, in front of Katagiri..." Tears fell from her eyes.

"Just for a little while... can I be pampered?"

"If I can do something..." While I searched for the rest of my words, Anri slowly approached. She gently sat on my lap. "Sorry... am I heavy?"

"No," silence flowed through the dojo.

"Sato-kun... you're warm, aren't you?" Anri's voice echoed softly. "You risked your life to save me... and accepted my weaknesses too..." Her shoulders trembled slightly.

"I'm... so tired".

"Anri-san..."

"Hey, just like this... for a little while". Anri's breathing gradually calmed, as if released from all burdens. I remained silent, savoring this moment. The honest weakness of someone who had tried to be strong. I felt gratitude for being able to accept it.

"Thank you..." Anri whispered. "Sato-kun... for being by my side. I've never shown anyone this side of me". Anri, whose neck was flushed red, squirmed on my lap. It was a lovely gesture, unimaginable from the dignified figure she presented at tournaments.

"Anri-san, it's okay. You can be more pampered".

"Eh...? B-but..." Her sharp gaze in the dojo was now filled with embarrassment. I gently hugged her closer. "Ah..." A small sound escaped her lips.

"You must have been struggling. Carrying it all by yourself".

"Yeah..."

"You don't have to try so hard anymore". Gently holding her, I loosened the tension in Anri's back, one by one.

"Sato-kun..."

"Yes?"

"This is the first time I've ever complained like this..." her voice trembled, but there was definite trust in it.

"You can always lean on me".

"Really?"

"Yes. Because I... want to accept all of Anri-san". At my words, Anri's body relaxed, as if a long-stretched string had finally loosened.

"I always thought I had to be strong".

"I understand".

"But in front of Sato-kun... somehow I can be honest". Only our quiet breathing echoed in the dojo.

"Sato-kun?"

"Yes?"

Anri closed her eyes. I gently kissed her lips. Anri's mouth opened, and she entangled her tongue with mine. Her warm, soft tongue explored my mouth as if seeking something.

"Sato-kun... you're getting hard," Anri said. Just as Anri said, I was so excited that I had an aching erection. The sensation of Anri's butt on my lap further stimulated my penis.

"Anri-san... I..."

As Anri and I embraced and shared a deep kiss, the entrance door suddenly opened.

"Onee-chan? I came to the dojo to prepare for tomorrow... Huh?" Kokoro's voice broke the silence.

Anri quickly got off my lap. Anri and I hastily put some distance between us. But we had already been seen.

"Why...?" Kokoro's face showed confusion, and her eyes reflected confusion and anxiety.

"Kokoro," Anri-san's voice was unusually gentle. "Come here for a moment".

"But..."

"It's okay. Come". Kokoro approached hesitantly. The setting sun illuminating the dojo floor cast long shadows of the three of us.

"Kokoro, listen,"

"What...?"

"Look at Sato-kun's face". The scars on my face, pale bruises, a torn lip. "It's a terrible injury, isn't it?" Kokoro stared intently at my face.

"He challenged Katagiri".

"Eh...?" Kokoro's eyes widened.

"For us..." Anri's voice trembled. "He confronted Katagiri's paralysis ability head-on. Sato-kun... to protect our dignity".

"But... then..."

"Yeah. He lost, almost got killed, and was hospitalized. But... even then, Sato-kun didn't run away". Tears welled up in Kokoro's eyes. "For us... such an injury..."

"That's why..." Anri took Kokoro's hand. "You don't have to hide anymore. Sato-kun knows everything about us. Even so... he accepted us".

"Onee-chan..." Kokoro's voice choked.

"Sato-san... really?"

I nodded quietly. "Kokoro-chan, I... have a special ability". In the twilight dojo, the three of us sat on the tatami mats in seiza.

"Ability...?" Kokoro tilted her head, while Anri nodded silently beside her.

"When I touch an object... I can see the memories left in it".

"Memories...?"

"For example," I stood up and touched the shrine placed in the corner of the dojo. "This shrine holds the memory of Kokoro-chan practicing karate alone yesterday morning. You practice quite early in the morning, don't you? There's a memory of you doing straight punches while crying".

Kokoro's eyes widened. "Eh...? No... I didn't tell anyone".

"That's right. When I visited you in the hospital, I used my ability to see memories from Anri-san's smartphone that was in the living room. The events with Katagiri that day... and what happened after... the park, the movie theater, the train..." I chose my words carefully as I continued. Kokoro's face turned pale. Anri gently embraced her sister's shoulder.

I exhaled deeply and continued, "The stronger the emotions in the memories, the clearer I can see them".

"Then... ours..."

"Yes. Both your fear, your regret, your sadness. Even your pleasure and joy, I saw everything". Tears welled up in Kokoro's eyes.

"So... you know everything? That side of us...?"

"Yes. But," I looked at Kokoro with a serious gaze, "Actually... in my fight with Katagiri, I was almost killed. At that time... something strange happened". I looked at my palm. "The ability to erase people's memories suddenly awakened within me".

"Erase... memories?" Kokoro's voice trembled.

"Yes. And... with that power," I exhaled deeply and continued, "I erased everything about you two from Katagiri and the others' memories. I also... completely destroyed his smartphone".

"Eh...?" Kokoro gasped.

"In other words... you two are free now". A heavy silence fell in the dojo. "Only I and... the records on this smartphone know. Katagiri and the others have completely forgotten about you two".

"Is that... true?" Kokoro's voice was hoarse.

"Yes. So... you can rest assured now".

At that moment, Kokoro broke down crying. "It's good... it's good..." Anri also clung to Kokoro, weeping.

"But... Sato-san," Kokoro said tearfully, "Such a dangerous thing... for us..."

"It's alright," I smiled quietly. "If your smiles return, then that's all..."

"Sato-san..." Kokoro rushed over to me.

"Thank you... but please, no more dangerous things..."

"It's alright," I looked at them both. "From now on, as ordinary high school students. As karateka. And..." my words caught in my throat, "As important people... I want to protect you both".

Anri touched my cheek with a trembling hand. "Sato-kun... we will absolutely..."

"Never forget this favor," Kokoro continued. In the moonlit dojo, Kokoro-chan's voice trembled softly. "I'm... struggling too..." Her words were filled with emotions she had desperately suppressed until now.

"Sato-san... can I also borrow your lap... please?" Her voice held a weakness she had never shown before.

"Please..."

"Kokoro..."

"Because Onee-chan was hogging it just now," Kokoro's cheeks flushed red in the moonlight. "I want to be pampered too".

I quietly straightened my knees and sat back down. "Of course," Kokoro gently approached and tentatively sat on my lap. Her small body trembled slightly.

"Am I... heavy?"

"No, you're fine,"

"I'm lighter... than Onee-chan, right?"

"Kokoro!"

At Anri's voice, Kokoro chuckled softly. But tears were still mixed in with her smile.

"Sato-san... you're warm," Kokoro's voice echoed quietly in the dojo. "I've been so scared... all this time".

"Yeah."

"But now... I feel safe". Anri gently stroked Kokoro's head. "Kokoro... it's okay now".

"Yeah..." In the dojo's silence, Kokoro's breathing gradually calmed.

"Sato-san?"

"Yes?"

"Will you... stay by our side from now on?" Her question was filled with pure trust.

"Yes, I promise".

"Okay, it's my turn now!" Anri lightly pushed Kokoro's shoulder.

"No! Onee-chan, it hasn't even been five minutes yet!"

"But you were sitting there for ten minutes earlier, weren't you?"

"It was three minutes!"

"Just switch!"

"Ugh!" As Kokoro stood up grumpily, Anri immediately sat on my lap.

"See? Onee-chan suits Sato-kun better, right?"

"Mmph..." Kokoro-chan puffed out her cheeks.

"Sato-san! Compare us and tell us which is better!"

"Eh? Ah, wait..." As I flustered, Kokoro raised both hands.

"Okay! Lap comparison, start!"

"Kokoro! I just..."

"Switch!" Kokoro jumped onto my lap, almost pushing Anri aside.

"See, I'm definitely lighter and cuter, right?"

"What do you mean by that? In that case..." Anri stood up with a serious expression.

"My body, trained in karate, isn't just for show".

"Onee-chan, does that mean it's hard and heavy?"

"Wh-what!?" I burst out laughing without thinking. The two sisters turned around simultaneously.

"Ah, Sato-kun is laughing".

"Sato-san, are you making fun of us?"

"I-I'm sorry... but," I wiped away my tears as I answered, "You two look so energetic after a long time..." At my words, the sisters' expressions softened.

"That's true..."

"Yeah..."

"Alright! Then it's my turn next!"

"But! You just sat down!"

In the moonlight, the sisters' laughter echoed. I felt the tense atmosphere gradually melt away.

"Geez, you two..." At my words, the sisters turned around simultaneously.

"Which one is better?"

"That's right, choose, Sato-kun".

"Um..." Seeing my troubled expression, the two looked at each other and then burst into laughter. Their bright voices echoed in the dojo.

"Both of you are wonderful". In the moonlit dojo, I quietly spoke.

"Your unique qualities shine with completely different brilliance".

"Eh...?" The sisters looked up simultaneously.

"Anri-san..." I smiled gently. "You have a dignified beauty. Your serious practice in the dojo is like a Japanese sword. There's a sharp strength and elegance about you". Anri's cheeks flushed faintly.

"But your occasional weaknesses and moments of being pampered are also endearing. The delicacy within your strength makes Anri-san even more charming".

"N-no... if you say it like that..." Anri covered her face.

"Kokoro-chan," I turned my gaze to the younger sister. "You're like the spring sunshine. Bright, warm, and seeing you calms my heart. You have pure strength and honest kindness". Kokoro fidgeted, wringing her hands together.

"And your feelings for your sister are truly pure... that earnestness has touched my heart many times".

"B-but... Onee-chan is..."

"Anri-san's dignity and Kokoro-chan's cuteness. They're like the moon and the sun..."

"Hey!"

"Please stop already~!" The sisters exclaimed simultaneously. Both of them, completely red-faced, sat back down, leaning on each other.

"It's too embarrassing..."

"Sato-san, your choice of words is unfair..."

"But it's the truth," my sincere voice made them blush even more. "Anri-san's strengths and weaknesses, Kokoro-chan's brightness and innocence. All of it is an irreplaceable treasure".

"..."

"..." The sisters seemed speechless, gripping each other's hands tightly.

"From now on, please continue to show me your different forms of brilliance". In the moonlight, the sisters' eyes welled up.

"Sato-kun..."

"Sato-san..."

"Being able to protect your smiles is my pride". Outside the window, stars gently twinkled, as if blessing their different forms of brilliance.

One night, I was sitting with the sisters in the dojo. Moonlight streamed into the dojo, and a pleasant breeze flowed through the stillness.

"Hey, Sato-kun," Anri suddenly spoke. "Won't you... with us?"

I froze at the unexpected words. "O-onee-chan!" Kokoro tried to stop her in a flustered manner, but Anri held up her hand.

"It's fine, isn't it? Kokoro's been holding back a lot lately, I can hear her comforting herself every night all the way from my room". Her expression was serious, her eyes sincere. "Sato-kun also worked hard, risking his life. Don't you think you deserve a reward from us?"

"B-but... Sato-san has his own feelings..." Kokoro looked up at me anxiously.

"It's okay. Kokoro, just be honest. You can't hold back anymore, can you?"

"Eh...?" Kokoro looked surprised at Anri's words.

"Onee-chan..."

"The two of us will make Sato-kun feel good. How about it?"

"B-but..."

"Right?" Anri invited again, and I almost nodded without thinking. (No... I'm about to succumb to my desires.) My rationality barely kicked in, and I shook my head.

"I'm sorry..."

"Why?"

"Because... there's no way I can do something like that".

"But we're serious, you know?" Anri stood up and faced me. Anri's figure, illuminated by the moonlight, was almost mystical.

"We've been defiled both body and soul, Sato-kun, we want you to purify us. Right? Please? Sato-kun, let's feel good together?" Anri smiled gently. Her expression was as beautiful as an angel.

(No... she's too cute, I want to hold her!)

"Hey, Kokoro, you tell him too".

"Eh..." Prompted by Anri, Kokoro opened her mouth. "Sato-san... let's be happy together? I've actually been holding back for a long time too..." Kokoro pleaded with an upward glance. (Even Kokoro-chan...) My resolve was about to break. "Hey, Sato-kun... I can't hold back anymore..." Anri whispered in a pained voice.

"Sato-san, I'm at my limit already..." Kokoro clung to me, tears welling in her eyes. The sweet scent of the two wafted over me, violently shaking my rationality.

"But, at least not in the dojo..." I desperately tried to resist, but their hands were relentless.

"No... my switch has already been flipped..." Anri kissed my neck.

"Sato-san, let's do it quickly? We've been holding back for so long, you know?" Kokoro affectionately stroked my cheek.

"Alright..."

I took the two of them to the corner of the dojo.

"Okay, here we go..." I pulled down my pants and boxers in one swift motion. As my erect penis was revealed, their eyes were fixated on it.

"It's big..."

"It's thick..." Anri and Kokoro exclaimed in admiration.

"Both of you... go ahead..." I stood in front of them and offered my penis.

"Anri-san, can you lick from the right... Kokoro-chan, from the left?"

The moment I spoke, their mouths opened simultaneously. "Yes!" Anri went to the right, and Kokoro went to the left. Then, they looked at each other and almost simultaneously attacked my penis.

"Mmmph...!" My penis was vigorously moved up and down in their warm mouths.

"Slurp, slurp..."

"Chup, chup..." Their alternating fellatio techniques were like a harmony.

"Ah... it feels so good..." I couldn't help but let out a voice. Gently embracing their heads, I surrendered to the pleasure. "Suck harder..."

"Mmmph...!"

"Chubba...!" The two, as told, sucked my penis with more force. Their tongues raging in their mouths relentlessly stimulated the glans.

"Ahhh... good... more..." I stroked their heads, trembling with pleasure. Eventually, I neared my limit and couldn't help but cry out.

"I'm cumming...!"

SPLURT! White, cloudy semen was released onto their faces and into their mouths.

"Mmmph!"

"Mmmph!" They widened their eyes and endured the impact. "Sorry... are you okay?" I worriedly looked at their expressions. Then, they smiled happily and opened their mouths.

"It's okay... it's warm".

"Sato-san's semen is thick~" The two, as if they had found a treasure, wiped their mouths with their tongues. They were also licking the semen off each other's faces.

"Then next..." I stood up and pulled open the front of my dojo uniform. "Kokoro-chan, can I enter from behind?"

"Yeah... use my pussy however you like". Kokoro turned around, lowered her dojo pants and underwear, and offered her smooth pussy. I embraced Kokoro's body from behind and brought my penis close to her pussy.

"Then, here I go..."

THWUMP! Soft, slippery pussy flesh enveloped my glans. Kokoro's well-lubricated pussy easily accepted my penis, which was inserted deep into her vaginal wall in one go.

"Ahhh... it's in... so deep!" Kokoro's sweet voice echoed. When I reached deep inside Kokoro, I felt the warm, soft sensation of her cervix. Her vaginal walls tightened, embracing my penis.

"It feels good... Kokoro-chan's insides are warm..."

"Me too... Sato-san's penis hitting deep inside feels so good..."

"Sato-kun's penis is big and hard after all, isn't it..." Anri whispered to Kokoro from the side.

"Yeah... it's getting bigger and bigger inside me..." Kokoro also let out a cry of pleasure, moving her hips.

"Ah... ah... haah...!" Kokoro's small breasts bounced up and down with the piston movements.

"Wow... Sato-kun's penis is making Kokoro's pussy spread out ridiculously wide..." Anri exclaimed in admiration from behind Kokoro.

"Ahhh, it feels so good! Sato-san's penis is rampaging inside me!" Kokoro arched her back and screamed.

"Haah, haah, thrust more! Thrust your penis into my pussy! Make me feel good!" As per her request, I accelerated the piston movements. "Ahhh, amazing! My mind is going blank! I'm cumming, cumming, cummingggg!" Kokoro convulsed and trembled, reaching her climax. "Haah, haah... haah..." She was out of breath, her breathing ragged.

"Did you come?"

"Yeah, but I still want to cum more~"

"Then let's do it in the missionary position next".

"Yeah!" Kokoro replied energetically and lay down on the dojo floor. "Please, Sato-san". Kokoro spread her legs apart, exposing her pussy.

"Please!" Responding to her invitation, I embraced Kokoro's body and brought my penis closer to her pussy.

"Ahhh... here it comes!" Kokoro welcomed my invading penis with a joyous expression.

"Ahhh... it's in all the way... I'm so happy!" My penis, deeply inserted into Kokoro's vagina, hit her cervix, and I too let out a cry.

"It feels good! Kokoro-chan's insides are the best!"

"Me too! I love Sato-san's penis! I love you!" Tears flowed from Kokoro's eyes. "Wow... Kokoro-chan, are you crying?" Anri asked, surprised.

"Yeah... I just got so happy... it really feels so goodddd" Kokoro replied, laughing.

"Then, I'll thrust hard for you," I resumed the piston movements. Thwack thwack thwack thwack thwack "Ahhh... haah... Sato-san...!" Kokoro's sweet voice and the sound of hips hitting echoed throughout the room.

"Ah! It's thrusting deep! It feels so good!" Kokoro's body reflexively arched. "Haah, haah... I'm cumming, cummingggg!" Her screams coincided with her body convulsing violently. "Phew... phew... haah..."

"Kokoro-chan... I love you... I love you so much!" I called Kokoro's name, moving my hips vigorously. "Oh! I'm cumming! I'm cumming repeatedly!" Kokoro shouted loudly, her body trembling violently. Each time, her pussy squeezed my penis tightly.

"Ahhh... it feels too good... Sato-san's penis is so thick and hard... my pussy is completely filled!"

"Sato-kun, thrust harder! Fill Kokoro's inside with your penis!" Anri interjected from the side.

"Yeah! Got it!" I moved my hips and began even more vigorous piston movements. "Ngyaah! Ahyuu! Eugh! Eugh!" Kokoro's body bounced, and her moans echoed throughout the dojo. "Amazing... I'm cumming now! I'm cumming over and over again!" Kokoro's voice rose, echoing loudly in my ears. "Kokoro-chan, you're cute... your pussy is the best..." I hugged Kokoro's body from behind and sped up the piston movements.

"Wow..."

"Sato-kun's penis is thrusting hard into Kokoro's pussy..." Anri exclaimed in admiration. "Kokoro-chan... does it feel good?"

"Yeah! It feels the best! I can feel Sato-san's penis rampaging inside me! It's so amazing how deep it goes! Ahhh... I'm cumming! I'm cumming now! Cummingggg!" At that moment, Kokoro's body convulsed violently. At the same time, her pussy tightened even more fiercely.

"Ahhhh! I came! I came! Sato-san's penis made me cummm!"

Eventually, I too neared my limit, and semen surged within me again. "It's coming out...!" SPLURT! This time, it was released deep inside Kokoro. "Ahhhhhhhhhh!" Kokoro screamed, ejaculating a large amount of cum.

"Ahhh... Sato-san's sperm is raging inside me..." Kokoro moaned sweetly, her body trembling. "Sorry... for being rough".

"No... it felt good..." Kokoro smiled. We remained embracing for a while, still.

"Sorry, I came so many times..."

"It's perfectly fine, I'm happy that Kokoro-chan felt good".

"Thank you... Sato-san, I love your penis..."

"Me too, I love Kokoro-chan's pussy". Confirming our love, we shared a deep kiss.

"Mmmph... kiss... lick..." Our tongues intertwined, tasting each other's mouths.

"Next is me... Sato-kun, hurry up and put it in! I can't hold back anymore!" Saying that, Anri stood up and took off her dojo pants. What lay beneath was her thighs, wrapped in cute panties. Her crotch was already overflowing with cum, shining through the panty fabric. Slowly, she took off her soaking wet panties, and her hand reached for my penis.

"Haa haa... look, it's so wet already".

"It's hard and hot... Sato-kun's penis..." Just as she said, Anri's hand gently enveloped my cock. Then, it was slowly guided towards Anri's pussy. "Thrust in all at once... rampage inside me!"

SLURP! "Ahhh! It's here! It's hard! A big one just entered!" The moment it was inserted, a cry of joy escaped Anri's lips. My penis was enveloped in her tightening warmth, instantly dragged into a world of pleasure. Thwack thwack thwack thwack... "Wow... Sato-kun's penis is making my pussy spread this much..." Anri said, looking at her crotch.

"Haah... haah... thrust harder! It feels good!" Anri vigorously thrust her hips, screaming loudly. Her appearance was truly like a beast.

"Ahhh... I'm cumming... I'm cummingggggg!" And then, Anri's body convulsed violently. At the same time, a large amount of cum sprayed from her pussy, making my penis even hotter.

"Phew phew... mmmph! Ahhh!" Anri, out of breath, wore a satisfied smile. But I grabbed Anri's hips and sped up the piston movements even more. Thwack thwack thwack thwack thwack thwack "Ah! It feels good to go thwack thwack thwack! It feels good! Thrust more!" Anri vigorously thrust her hips herself. Her pussy made a squeaking sound as it tightened, pleasuring my penis.

"Thrust deeper! Thrust so deeply that it reaches my uterus!" When she said that, I thrust my hips forward with all my might. Then, my penis reached Anri's cervix.

"Ahhhhhhhhhh! It's hitting my uterus! This is it! This is what I wanted!" Anri screamed. At the same time, her pussy tightened even more. "Ahhh... I'm cumming... I'm cumming repeatedly". Every time Anri's body convulsed violently, cum splashed from her pussy. It landed on my face and chest, further increasing my excitement. "More... thrust more! Destroy me!" Thwack thwack thwack thwack thwack I resumed the piston movements. Anri's pussy squeezed tightly, as if it wouldn't let go of my penis.

"Ahhh! It feels too good! I've never had sex like this before! I'm cumming constantly!" Anri continued to cry out in ecstasy. Watching her, I maximized my own pleasure.

"Ahhh! Something amazing is coming! This time I'm really going to cum!" And then, Anri's body convulsed violently again. Anri spasmed, eyes rolled back, and at the same time, an even greater amount of cum than before sprayed from her pussy. At the same time, I ejaculated a large amount of semen into Anri. After that, we continued to intertwine many times, covered in sweat. Finally, it became a time when the two of them would be worried if they didn't go home, so we finally put our dojo uniforms back on.

"Sato-kun! Mmmph haah haah" Anri panted, approaching me. Her black hair shone, and her dignified posture had regained its usual beauty.

"Sato-san! Haah haah ah" Kokoro approached from behind. Her refined features, similar to her sister's, had regained their innocent smile. Both of them were still breathing heavily. Their sweating foreheads and dojo uniforms exuded an increased sense of dignity.

"I... wanted to thank you," Anri's voice trembled, but it wasn't from fear. It was a warm tremor, as if overflowing with gratitude.

"Thanks to Sato-san..." Kokoro's eyes welled up, but these weren't tears of pain. They held a new light, full of hope. "We've become well again". Anri's voice had regained its strength. Her profile, once said to be the most beautiful in the neighborhood, shone. "Yeah! We're okay now!" Kokoro nodded energetically.

Her gesture had regained its former innocence. The two chose to keep their memories. That meant they chose strength. And the joy of being able to support that choice spread within me.

"Truly... thank you," Anri bowed deeply. Her black hair cascaded like a waterfall.

"Me too!" Kokoro bowed similarly. The sisters' backs were perfectly straight.

"From now on, with us..." Anri's words were affirmed by Kokoro's nod. "Please have lots of sex with us!" Their voices overlapped. There was no longer any hesitation in their voices. I smiled contentedly, because this scene was what I had hoped for.

"Yeah! That's right! Thank you both today". With that, I left the dojo. From behind, their voices saying "Thank you" followed me. I walked on, a definite sense of fulfillment in my back, having witnessed their new beginning. This memory will surely never disappear. It will remain as one of the most beautiful scenes in my mind.
