Ichika? No, she went out with Nanami... Wait, is this Nino? Why is she dressed like Ichika?
Next door, Kaede watched the scene unfolding in Rin's room through the camera system.
Kaede had never met the other sisters, let alone learned how to distinguish them, but they were already on her system's "Target List." Through the data overlay, she could see that the girl Rin was currently kissing was Nino, Ichika's younger sister.
Does he think she's Ichika? No, that doesn't make sense... He and Ichika haven't even gone that far in private. Aside from that one practice kiss, Ichika had mostly just talked a big game. Kaede didn't know what Nino was plotting, but she had been looking for a way to help Rin conquer the sisters without Ichika finding out. This was perfect.
Inside the room, Nino's mind was a complete blank. As Rin's lips occupied hers, only one thought cycled through her brain: My first kiss... is being stolen?
After the initial shock, Nino forgot all about her "Ichika" persona. She reached out to shove him away, but Rin was faster. While she was dazed, one of his hands slid under her blazer, gliding over her flat, tight stomach to her chest, pushing her bra up and over her breasts.
Simultaneously, his other hand snaked up her thigh, sliding under her skirt. His fingers hooked into the edge of her panties, finding and clamping down on her most sensitive spot with surgical precision.
The moment she tried to push back, Rin gave a sharp, expert squeeze. The strength left Nino's body instantly. Her mouth was blocked, so her protests came out as pathetic, muffled whimpers.
"Mmm... Nnngh!!!"
Her legs turned to jelly. She tried to clamp her thighs shut to stop his invasion, but he already had full control of her clit.
With a little "optimization" help from Kaede next door, it took only minutes for Rin's hand to become soaked with her nectar. However, Rin didn't intend to take her virginity right then. He had a different plan.
"Mmmmph!!!!" As the girl in his arms stiffened and hit her limit, Rin's fingers probed deeper until they brushed against the barrier of her maidenhood. Only then did he pull away, acting as if he had just realized something was wrong.
Nino stumbled back, collapsing onto the edge of the bed, frantically clutching her skirt. Her thighs were still stained with a glistening trail of her own excitement.
"You pervert! What did you do to me!?" Nino's eyes were teary, matching the wetness on her legs. "You monster! You're dead! I'm telling Ichika you did these disgusting things to me!"
"You... You're not Ichika!?" Rin acted shocked. "Who are you?"
"I'm Nino! And you're finished! Just wait until I tell Ichika!"
"This... this is just a misunderstanding," Rin replied. He didn't look panicked at all, which frustrated Nino. "Besides, you dressed up as Ichika to come find me. If Ichika finds out you tried to seduce her boyfriend while pretending to be her, what do you think she'll say?"
"Hah!? Are you insane? When did I seduce you? You're the one who started touching me the moment I walked in!"
"I started it, sure, but from Ichika's perspective, you came here in disguise to lure me in. That's going to be hard to explain."
"I..." Nino was stumped. She had planned to use this as blackmail, but he had turned it right back on her.
"The best thing to do is pretend this never—"
Before Rin could finish, a familiar voice echoed from the yard.
"Rin! I forgot my keys, open up! Oh? The door's unlocked? I'm coming in~"
"!!!!" Nino's heart nearly leapt out of her chest. "Ichika's back! She can't see me like this! Is there anywhere to hide!?"
The sound of bare feet on the wooden floor approached from the hallway, followed by the creak of the stairs. Nino, in a total panic, dove under the bed.
"Don't let her find me!!" she hissed, poking her head out briefly. "Kiss her and tell her you want to do it so she goes to take a shower!" Then she pulled back into the shadows.
"..." Rin was speechless.
The person who said they forgot their keys definitely wasn't the real Ichika—it was Miku, Yotsuba, or Itsuki. But judging by Nino's reaction, they hadn't planned this as a group.
"Rin?"
The "Ichika" voice called out from the hallway. Rin opened the door to find a second girl in a school uniform.
"Why did you change clothes?" Rin repeated his line from earlier.
"I went home to grab some things and changed."
Do these quintuplets have a hive mind? Rin wondered. How are their excuses identical?
"I see... come in." Rin led the second "Ichika" into the room.
Under the bed, Nino clenched her fists. Kiss her! Fuck her brains out! Just do it so I can escape while she's in the shower!
Normally, Nino could tell her sisters apart even in disguise, but from her vantage point, she could only see ankles. Since she didn't have an ankle fetish, she was convinced the newcomer was the real Ichika.
Rin, however, knew better. But a kiss is a kiss.
"Wearing your uniform even on a break... Ichika, are you really that thirsty?"
"Eh? Mmmmph!!!!"
Rin lunged, capturing the second girl's lips. His hands expertly found their way under her clothes. Since his fingers were already lubricated with Nino's juices, he skipped the warm-up.
This "Ichika" was slightly weaker than Nino. Whether it was a lack of stamina or just pure shock, she couldn't resist his touch. Following the same routine, Rin muffled her identity with a kiss, teased her into a messy climax, and then "realized" she wasn't Ichika only after feeling her hymen.
"Mmm... you pervert..." This girl's personality was softer than Nino's. While Nino had the energy to curse him, this one just sniffled and wiped her eyes.
Under the bed, Nino was losing her mind. She had been rooting for Rin to distract "Ichika," but this wasn't Ichika either? Then who was it? And because of her plan, another sister was being molested.
Nino was filled with regret. Meanwhile, Rin looked at the teary-eyed girl. He ruled out Ichika and Nino. It wasn't Yotsuba—he didn't feel any athletic muscle tone in her stomach or thighs; she was soft. It wasn't Itsuki, the "Meat-Bun Monster," who would likely have more of a presence.
"You're not Ichika. You're... Miku?"
"Eh?" Miku looked up, stunned that he recognized her.
Miku wasn't as sharp as Nino, but she shared the same goal: keeping the sisters together. After hearing the landlady's words yesterday, she'd come up with the same "test" as Nino. But she never expected him to see through it so easily.
Every teacher and classmate at school failed to tell them apart, yet he knew exactly who she was even through a wig and makeup. Her grandfather was right: The one who loves you will never mistake you.
"I'm sorry, I thought you were Ichika at first," Rin apologized.
"I-it's... it's okay..." Miku stammered, her face crimson as she squeezed her wet thighs together. "It was just an accident. Please... don't tell Ichika."
She turned to leave, but then, the voice returned to the yard.
"Rin! I forgot my keys, open up! Oh? The door's unlocked? I'm coming in~"
The room went dead silent.
Miku's face was a mask of terror. "Ichika's back... No, no, no! She can't find me here! If she thinks I'm trying to steal her boyfriend, it's over!"
She panicked, looking around like a trapped animal until her eyes landed on the bed. Rin tried to suggest the wardrobe, but the footsteps were already on the stairs. Miku dove under the bed.
As she scrambled into the dark, she saw a terrifying sight: she wasn't alone.
Miku opened her mouth to scream, but Nino's hand clamped over it. The two sisters stared at each other in the darkness, paralyzed with shame. Miku looked away, realizing Nino had heard the whole thing—the wet slaps of the fingers, her high-pitched moans, and the sounds of Rin sucking her tongue.
"Rin? Is something wrong?" The third "Ichika" asked as she entered.
"Nothing..." Rin looked at the newcomer. Two options left: Yotsuba or Itsuki.
Well, I've already taken three of their first kisses today. What's one more?
Rin pulled the third girl into a deep kiss, his hands immediately finding her breasts and thighs. This time, he felt it—the firm, toned muscles of an athlete.
Yotsuba.
Yotsuba didn't push him away. She was strong enough to do so, but she was conflicted. Part of her thought, If I fight too hard, I might hurt him. And another part... So this is what a kiss feels like? It actually feels kind of good.
And his fingers... they felt so much better than when she did it herself.
Noticing her cooperation, Rin became more aggressive. He slid his tongue into her mouth, exploring her heat. Unlike Nino and Miku, where he feared a bite, Yotsuba was yielding. He didn't stop at one climax; he toyed with her every sensitive spot, his rougher fingertips sending jolts of electricity through her body.
"Ahhn... mmm~"
Yotsuba's soft, lewd moans drifted under the bed, making Nino and Miku's skin crawl. They both thought, This time it has to be the real Ichika.
"I... I'm going... again!!!!" Yotsuba arched her back, her panties failing to contain the flood of pleasure. After climaxing twice in his arms, she had no idea how to explain herself.
Rin pulled back, looking concerned. "You're... Yotsuba?"
Yotsuba froze. The two under the bed froze.
"I... I'm..." Her lips trembled. She was a "deer in the headlights."
"I-I'm Ichika, you know...?" she squeaked, trying to hide her face in her hands.
"If you're Ichika, then who's coming in downstairs?" Rin asked, suppressing a laugh. "I thought you were Ichika because you seemed to be enjoying it so much."
Yotsuba's face turned nuclear.
"Rin! I forgot my keys, open up~" A familiar voice echoed from the yard.
Total silence.
"Please, don't tell Ichika! I'll do anything!!!" Yotsuba begged, diving under the bed.
She saw her two sisters waiting for her. She offered a sheepish, awkward grin. "H-hey guys... what a coincidence... hahah..."
Nino and Miku were beyond words. The fourth "Ichika" was now upstairs. Rin looked at the bed. They have enough for a three-player game down there. One more and they can play mahjong.
The last one had to be Itsuki. Rin pulled the final "Ichika" into the room.
"Rin, this smell..." Itsuki sniffed the air. She noticed the small puddles on the floor. Before her brain could identify the scent of sex and juices, Rin captured her lips.
"Mmph!?" Itsuki's muffled squeak reached the sisters below.
Nino was officially numb. The same script had played out four times. She knew the girl outside was Itsuki, but no one dared to come out. If they revealed themselves now, the "disgrace" would be permanent.
Unlike the others, Itsuki didn't resist or enjoy it—she just turned into a statue. She knew couples did this, but she didn't know Rin and Ichika were the "kiss on sight" type!
Itsuki considered herself the "mother" of the group. If Ichika found out, she'd be the one who broke the family apart. She was so traumatized she didn't even notice Rin's fingers invading her skirt until he pinched her clit hard. She shrieked and shoved him away.
"Ichika? No... Itsuki!?" Rin acted surprised.
"I... uh..." Itsuki couldn't look him in the eye. Even though she hadn't reached a full climax, she was "leaking," and she was mortified. "P-please... keep this a secret! I beg you!"
"Keeping it a secret is going to be hard if I'm the only one who knows," Rin said.
"Eh? Ichika... No, Yotsuba!?"
Rin kicked the bed frame. Yotsuba crawled out, followed by Miku, then Nino.
Itsuki stared at her three sisters, all dressed as Ichika. "W-what is wrong with you people?"
"We were... testing him," Nino muttered, unable to maintain her "queen" attitude in such a pathetic situation.
Itsuki looked at their messy uniforms and realized they'd all been through the same "inspection." She sighed. "This is our secret for life. Ichika must never know. Understand?"
"Yes." "Okay." "Understood."
They all turned to Rin. He had a wicked, playful grin on his face.
"W-what do you want!?" Nino barked, clutching her body. Her wet panties were a cold reminder of what he'd just done to her.
"Pervert," Miku whispered, backing away.
"If you want to do something perverted, just do it to me!" Yotsuba stepped forward bravely. "I won't let you hurt them! I'll take responsibility for everything!"
"I... I can take it too!" Itsuki added, trying to be the "mother."
"Tsk, tsk... do you really think I'm that kind of person?" Rin asked.
"Aren't you?" Nino snapped. "You recognized us all along, didn't you!? You pretended we were Ichika on purpose! If Ichika finds out you touched all of us, she'll dump you!"
"Maybe," Rin smirked. "But you all dressed up as her to seduce your sister's boyfriend. That's a 'backstabbing' move. Maybe I should tell Ichika... she might forgive me for my honesty. It's better to come clean now than let it leak later, right?"
"No!" Nino pleaded. If Ichika found out, the sisters would be torn apart forever.
"Hehehe," Rin laughed. "I'll keep your secret on one condition. If you do this one thing, I won't say a word."
"What is it?" Itsuki asked seriously. "Anything."
"Anything?" Rin smiled. "Don't look so grim. I'm not a monster. My condition is simple."
"On the next exam, every one of you must pass at least one subject."
The four sisters stared at him in disbelief. Then, they screamed in unison:
"THAT'S IMPOSSIBLE!!!!!"
