Chapter 156 Signature name
Edited by: Kanaa-senpai
Behind the school building lay the Little Forest, a well-known spot for after-school scraps.
The cherry blossom trees there were considered hallowed ground for romantic confessions, and if you ventured just a bit further back, it was a legendary haven for outdoor hookups.
Seeing the look on Sakuramiya Saya’s face, Aki knew instantly that this tall schoolgirl—who was secretly absolute filth down to her very bones—was letting her imagination run wild.
But then again, it made sense.
After all, she was a literal Hentai Heroine.
Besides, girls were honestly just as horny as guys; they were just way better at keeping it under wraps.
As the saying goes: once a girl embraces her freaky side, guys can’t even compete.
Of course, the reverse was true too—when a guy really dialed up the charm, girls didn’t stand a chance either.
Since there was still a chunk of time left before the morning bell, Aki decided he might as well lock this situation down completely.
While he stood around waiting for the Sakuramiya sisters to change out of their gym gear, he mapped out how he wanted to handle the upcoming conversation.
But the more he muddled it over, the more he realized that given his track record, there was no point in beating around the bush.
Going straight for the jugular and telling them they needed to team up for some good old-fashioned Dual Cultivation¹ was definitely the play.
By comparison, figuring out exactly why the younger sister, Sakuramiya Hinata, had gone out of her way to sign her name to that love letter seemed like the far more pressing mystery to solve.
The Sakuramiya sisters didn’t keep Aki cooling his heels for long.
Having swapped their gym clothes for their school uniforms, they quickly made their way over to the designated meeting spot.
”Yo, Saya, look at us meeting again so soon. And you must be Hinata-san,” Aki said with an easy smile.
He offered a casual wave to the schoolgirl approaching them, who sported a shoulder-length chestnut mane and stood at roughly the same height as her sister, though her figure was New York style voluptuous compared to Sakuramiya Saya’s.
”Morning, Aki-san~!” Sakuramiya Hinata chirped back excitedly, immediately latching onto her own stepsister, Sakuramiya Saya.

Within the dynamic of the Sakuramiya sisters, Sakuramiya Saya usually possessed the gentler, more compliant personality, but the moment they hit the sheets, their dominant and submissive roles completely flipped.
The usually loud, brash, and hot-tempered Sakuramiya Hinata turned into the one getting thoroughly teased and dominated in bed.
It seemed like every soft-spoken, mild-mannered schoolgirl harbored a surprisingly wild, aggressive streak deep down, especially when it came to fooling around.
Takamine Sayuri was exactly like that, and the quiet, bookish Sakuramiya Saya was no exception.
On top of that, since Sakuramiya Saya was the older sister, Sakuramiya Hinata acted like an absolute angel whenever she was under her sister’s watchful eye.
Aki caught sight of Hinata’s slightly disheveled uniform and the distinctly pouty, miserable look plastered across her cute little face, causing him to chuckle silently to himself.
He could easily picture what had gone down after he left: Saya had undoubtedly cornered her little sister in the changing room, thoroughly punishing the girl for snooping through her private love letter and taking the liberty of adding her own signature at the bottom.
”Hinata, apologize right this second,” Sakuramiya Saya commanded, pulling out the letter in question.
”Because you decided to act like a brat, you’ve gone and given Aki-san completely the wrong idea.”
Instead of backing down, Sakuramiya Hinata offered a polite, obedient little provisional bow first, then immediately scampered straight over to Aki’s side, boldly wrapping her arms around his.
”I know it was a little chaotic, but I’m completely serious, you know! Aki-san didn’t get the wrong idea at all.”
Sakuramiya Saya’s expression instantly stiffened. “Hinata… are you trying to tell me you actually harbor feelings for Aki-san?”
”Uh-huh!” Hinata nodded vigorously, squeezing her arms even tighter against him.
Her soft, ample chest—noticeably heavier than Sakuramiya Saya’s—pressed tightly against Aki’s arm and torso.
But Aki wasn’t the clueless virgin he used to be.
After being thoroughly broken in by a small army of busty schoolgirls, a little skinship like this wasn’t about to make him lose his cool on the spot.
Still, a good thing was a good thing, and the intoxicating, sweet scent unique to a young girl kept wafting past his nose, making him thoroughly enjoy the view.
Aki watched the sisters’ little domestic showdown unfold with genuine amusement; truth be told, it was his very first time experiencing a real-life harem showdown firsthand.
Yet, he didn’t feel even a shred of anxiety.
Completely lacking the self-awareness or guilt expected of the guy caught dead in the center of a romantic crisis, he simply enjoyed the drama like a spectator watching a prime-time show.
”Hinata… when I cornered you about this earlier, you literally told me you didn’t care about boys and didn’t feel anything for Aki…”
”Well, yeah, because you sprang the question on me out of nowhere, Big Sis! Of course I was going to say that. I mean, considering what the two of us already do together…” Hinata trailed off, casting a quick, uncertain glance at Aki.
Aki was just about to let them know he was already entirely in the loop when Sakuramiya Saya caught her sister’s drift perfectly. “So you only said that to keep me happy? When in reality, you’ve secretly felt that way about Aki this entire time…?”
She couldn’t even bring herself to finish the sentence, her face flushing with a mix of shame and irritation. “If that’s the case, why didn’t you just write your own love letter? Why did you have to go piggybacking on mine and sign your name right under mine?!”
Hinata flashed a wicked, playful grin. “Because you tried to jump the gun and leave me behind, Saya! Anderson’s old saying about sharing everything applies here, and two sisters using the exact same love letter to confess their love is a killer move.”
”See? It worked like a charm. Aki came running straight to us the very next morning~” Hinata added, giving Aki a deliberate, heavy wink.
Sakuramiya Saya found herself completely struck dumb.
Staring at Hinata as she snuggled intimately against Aki’s side, a storm of complicated emotions swirled through her chest.
”If things are really like that…” Sakuramiya Saya proved herself to be a self-sacrificing older sister to a fault.
After a long, heavy silence, she forced herself to speak up. “Then I’ll step aside. Hinata, I just want you and Aki to be happy together…”
”Huh?! Saya, what the hell is that supposed to mean?!” Hinata completely flipped out.
”You’re making it sound like I’m some homewrecker stealing your boyfriend! And besides, if you aren’t part of the deal, being with Aki wouldn’t even make me happy anyway!”
Having lived under the same roof for years, the two sisters were profoundly intertwined—not just physically, but emotionally.
They literally couldn’t imagine life without one another.
Ever since she laid eyes on Aki for the very first time, Hinata had been absolutely starving for a piece of him, but she had suppressed those urges purely because she couldn’t bear the thought of hurting Sakuramiya Saya.
But with Valentine’s Day right around the corner, she had noticed Sakuramiya Saya acting incredibly shady.
After doing a little stealthy detective work and uncovering the truth, her initial anger had instantly morphed into pure excitement.
Since her sister clearly liked Aki too, wasn’t this the perfect scenario?
The three of them could just dive right into a blissfully happy life together.
That was exactly why she had stealthily added her own signature to the bottom of the page.
”But… we’re sisters… and a throuple? What if… what if people find out…?”
Faced with a stubborn Sakuramiya Saya who was totally overthinking herself into a corner, Hinata felt a surge of genuine Bitter Parent Template² style frustration.
”Seriously, big sis, why did you try to sneak off and monopolize him in the first place? Didn’t we promise we’d stay together forever? I’m willing to overlook you jumping the gun, but now that I want in, you’re trying to lock me out?! Do you just not love me anymore?!”
At that moment, it was as if their structural dynamics completely inverted.
Hinata took charge like the older sister, ruthlessly lecturing Saya with a barrage of rhetorical questions that left the usually sharp, sophisticated schoolgirl looking completely dazed and overwhelmed.
Having thoroughly enjoyed the free entertainment, Aki decided it was finally time to interject.
”Hey, hate to break up the drama, but let me clarify something real quick…” He reached out, effortlessly scooping both Sakuramiya sisters tightly into his chest at the same time.
Feigning a perfectly bewildered expression, he stated, “Are you two living under a rock? You do realize I have casual, purely physical relationships with a ton of girls, right? I literally dragged Shinomiya back to my place just yesterday, and she’s still wrecked in my bed right now, unable to move.”
While the news of Aki taking Shinomiya home had been largely overshadowed by the massive gossip surrounding Masaru’s sudden school transfer, it was still fresh news.
The Sakuramiya sisters had definitely caught wind of the rumors.
In fact, because they had spent the entire previous evening anxiously waiting to see if Aki would respond to their letter, they had naturally kept tabs on his movements after school.
Neither of the sisters made a move to pull away from Aki’s sudden embrace, though hearing him lay out his casual debauchery so bluntly made a pang of instinctual discomfort ripple through their hearts.
Hinata recovered first, nodding her head. “We obviously knew about that. But it’s not like you actually have an official, exclusive girlfriend yet, right?”
”I read your love letter, and yeah, I wanted to see you guys. But that doesn’t mean I’m agreeing to become your boyfriend,” Aki replied, tapping his own forehead as the realization finally hit him.
It seemed like when he went back tonight, he was definitely going to have to clear the air about this exact topic with Shinomiya and Natsuha.
”Yeah. First off, let me make one thing crystal clear: I am a devout bachelor. I don’t do dating, and I sure as hell am never getting married.”
Sakuramiya Saya shot him a deeply suspicious, judgmental look. “Then why the hell are you sleeping around with so many different girls…?”
”That’s completely apples and oranges. Everything I do is entirely consensual; it’s not like I’m forcing anyone’s hand.”
Aki knew he sounded like an absolute piece-of-trash scumbag saying this aloud, but in order to completely squash any narrative track that might trigger a Bitter Parent Template scenario and make his rivals stronger, he had to play the villain.
”So… you came out here to find us purely because you want to get into our pants? You have zero intention of actually making things official?” Hinata asked, the reality of the situation finally clicking in her brain. “Even if the two of us are totally fine sharing you and dating you at the exact same time, it’s still a no?”
”Still a no,” Aki refused, his voice entirely unyielding. “As for the actual reason why… I can’t share that with you guys just yet.”
Cradled tightly in Aki’s arms, the Sakuramiya sisters laced their fingers together, staring deep into each other’s eyes with profound affection.
”Saya… it looks like our little screaming match earlier was a total waste of breath…”
”Yeah. Hinata… what do you want to do now?”
”Since Aki’s putting his cards on the table like that, I say you make the call, Sister Saya. If you’re down for it, I’m down. If you want to walk away, it’ll sting a bit, but I’d still rather choose being with you over anything else.”
The moment the words left her mouth, the chestnut-haired, busty schoolgirl felt Aki’s large, warm hands begin to shamelessly wander over her figure.
Her face flushed a brilliant crimson, and she gave an uncomfortable, involuntary little squirm.
Unlike when Sakuramiya Saya touched her, Aki’s hands were still separated from her skin by two distinct layers of clothing, yet the sheer wave of pleasure hitting her was instantly more intense than any direct contact she’d ever felt.
The searing, heavy heat radiating from his palms cut straight through the fabric of her school uniform.
It felt incredibly intense—far more blazing hot than Saya’s delicate, trembling hands whenever they got carried away in the dark.
It was a mirror image over on Sakuramiya Saya’s side.
Finding herself pressed this intimately against a male body for the absolute first time in her life, she involuntarily began rubbing her chest against Aki’s torso, her breath hitching as she drank in the intoxicating, distinctly masculine scent rolling off his skin.
