Once after school, Natsuha had seen Takagi walking with Tsukimi.
Since he was her classmate's boyfriend, she still had a vague impression of him.
So when she saw the photo, she immediately recognized the boy as that Takagi.
But now he…
Swatting away Sasaki's wandering hand, already groping her softness, Natsuha's expression darkened.
She hated people like this.
Without hesitation, she grabbed the phone and turned toward the school building—
Only for Sasaki to yank her back.
Knowing what she was going to do, Sasaki wrapped her in his arms again, and kissed her to calm her down before explaining:
"Don't rush. One photo isn't enough."
"If you tell Tsukimi and she confronts him, he could just say the girl's his sister. Then we'd tip him off."
"So be patient~"
"...Fine."
Momo, who didn't know what they were talking about and who was the boy and girl in the photo that made them react so strongly, couldn't help but blink.
"What's going on? Did that guy cheat? And who's this Tsukimi you're—"
Cutting Sasaki a sidelong glare, Natsuha pulled Momo close and whispered an explanation.
The situation wasn't complicated—just a few sentences covered it.
The only notable part was Sasaki's interest in someone else's girlfriend.
Hearing her lover's strange thoughts, Momo wanted to say something like "stealing someone's partner is wrong", but after glimpsing the photo, she pursued her lips but didn't say anything.
Sasaki was her first.
First hug, first kiss, first time..
In everything..
Even if they had parted ways afterward never to meet again, the mark he left on her heart would never fade.
Not to mention, he had accepted her handmade doll, her scars, and even thoughtfully bought her gifts to help conceal them.
To outsiders, these might seem like small things—but to her, they meant everything.
Before him, no one had accepted her dolls.
People who saw her scars assumed she was dangerous and avoided her.
So Sasaki was special to her.
That was why she could tolerate his… habits.
Because she never wanted to lose him.
'Hmm… even thought she didn't know about Natsuha's situation, but she knew that ...hers must be pretty rare.'
They might be able to accept their boyfriend's infidelity, but other girls definitely wouldn't.
After all, this wasn't some mediaeval period where a powerful guy could have a full harem of queens and concubines to continue his lineage.
If that Tsukimi girl found out her boyfriend was cheating… she would
definitely break up with him.
In that case… would it really count as Fuyumi stealing her away?
Unaware of Momo's internal thoughts, Natsuha misinterpreted her downcast expression as distress over Sasaki's infidelity and quickly tried to comfort her.
Sure, she also hated her lover's greedy, "wanting-every-pretty-girl-he-sees" attitude, but if Momo was already upset over this, things would only get harder.
After all, as far as she knew… excluding Tsukimi, the girl he hadn't conquered yet, he had six other girlfriends… one of whom was his fiancée.
And those were just the ones she knew about.
Who knew how many more he hadn't mentioned?
The more she thought about it, the angrier she got.
With a frown, she elbowed Sasaki in the stomach. "You playboy."
After scolding him, she turned back to Momo.
"Don't feel bad, Momo. We'll just have to keep a closer eye on him from now on. As for the ones before us… there's nothing we can do…"
"Huh?"
Confused by Natsuha's sudden reassurance, the girl shook her head.
"I'm not upset?"
"I was just thinking… is it really okay for Fuyumi to steal someone else's girlfriend…?"
After explaining, she nodded in agreement. "But you're right—we should watch him more closely. With so many girlfriends, he never has time to play with me~"
"..."
Something about Momo's tone when she said "play" felt… off.
Natsuha hesitated before asking,
"So… why did you come find him today?"
"To have sex, of course~"
No hesitation. No embarrassment.
Momo explained the reason of her arrival with a bright, cheerful smile.
"..."
Natsuha's brain short-circuited.
Although she was very bold and enthusiastic when she was with Sasaki in private, that was in private... When there were other people around, a normal girl would not say it so directly...
…Unless Momo didn't see her as an outsider at all?
Forcing an awkward laugh, Natsuha mumbled, "I-I see… Well, have fun tonight…"
…Wait.
Why did that sound so weird?
Why did it feel like she was handing her boyfriend over to someone else?!
Was she… some kind of cuckold?!
Oblivious to Natsuha's spiraling thoughts, Momo glanced at Sasaki in confusion.
"Tonight? But Fuyumi has club activities after school, then a part-time job… Wouldn't nighttime be inconvenient?"
"?!!"
"Huh?"
With her eyes opened wide, Natsuha stared at Momo's cheerful smile and swallowed hard.
"Momo… you're not planning to… have sex at school, are you?"
"That's impossible! There are so many people here—what if someone finds out?!"
But Momo had already done it at school once before.
Why would she listen to Natsuha's warnings now?
If anything, she tried to persuade her instead.
"It's fine~ Sure, there are lots of students, but there are plenty of empty classrooms too!"
"And if Natsuha helps keep watch, it'll be way safer~"
"..."
What?
'You want to sleep with my man… and have me stand guard?!'
Before Natsuha could protest with a blushing force, Momo, who was completely unfazed, continued:
"Don't you want more time with Fuyumi too?"
"..."
Well…
Sasaki did satisfy her thoroughly—but like Momo said, if they could have more time to be intimate, she would of course be happy and willing to do so.
But if she agreed…
Knowing him, it was only a matter of time before he'd demand she and Momo line up side by side, skirts lifted.
The thought of another girl seeing her like that—
Absolutely not!
Just as she mustered the resolve to refuse, Sasaki's slid his arm around her waist, pulling her into his chest.
His chin rested on her shoulder, lips brushing her sensitive ear as he murmured,
"Natsuha,
You really wanna say no? Don't you miss me? Getting tired of me already?"
"How heartbreaking~"
Tired?!
Being with him and havings sex with him was now... and always would be—her favorite thing.
How could she ever get tired?
She just didn't want anyone else seeing her… scissoring like that.
However, hearing his words, her resistance crumbled with every ragged breath as the girl practically melted against him, speaking in a hazy voice.
"Y-You'll definitely take advantage of others misfortune… and make some… ridiculous demand…"
"But don't you want those ridiculous demands?"
Suddenly, her deepest secret were laid bare, and Natsuha's face burned as she huffed.
"W-Who wants that?! I just—It's not like you'd listen if I refused anyway!"
"Don't make me sound that tyrannical. You're the one who always—"
Realizing he was about to spill private details to Momo, Natsuha panicked and clapped a hand over his mouth.
"S-Stop talking! You're the one bullying me! I just—I have to give in! Because… because I like you, idiot~!"
The sudden confession caught Sasaki off guard and his chest swelled with warmth, sweet as cotton candy.
Unable to resist, he captured her flushed lips in a kiss.
Watching them get lost in each other again, Momo pouted and squeezed between them.
At this point, resistance was futile.
Trapped between the two, Natsuha had no choice but to agree to their "one keeps watch, two have fun" proposal.
But she had conditions.
After all, she knew Sasaki too well.
So she insisted their chosen spot had to be completely hidden.
Momo patted her chest confidently.
"Leave it to me!"
Then, with a grin, she revealed her pick:
"The art room!"
