I Sealed Sukuna’s Finger#487+488: Senpai Wearing Only An Apron, Saeko Busujima Completely Addicted to the Backdoor
🕑 Added 2025-11-08 11:53:45 +0000 UTC"Kanon?" Realizing he'd accidentally bumped someone outside when opening the door, Bokue immediately looked out.
However, what met his eyes was a certain silver-haired girl known as the "Middle School Division's Saint."
"Uh, are you okay, Kanon?"
"I-I'm fine..."
Originally covering her head looking somewhat pained, Kanon Kanase hearing this familiar voice froze slightly. She looked up to meet gazes with the young man poking his head out from inside.
"Oniisan? Eh... why are you here? This place isn't..."
"Oh, I came to deliver things to my sister Yura."
Bokue pushed open the door to the outside hallway, bending down to pick up the dropped lubricant and stuff it back in his pocket before turning to face the silver-haired girl.
"Sorry. Didn't notice someone outside when opening the door."
"I-it's fine..."
Seeing the young man seriously apologize to her, Kanon's face flushed slightly.
"Actually, I was also careless. Wasn't paying much attention to surroundings while walking... oh right, I didn't know Oniisan's sister also attended this school?"
"Yeah. She's called Yura Keikain. Which specific class... I don't think I asked. But this is Yura's dorm room."
Bokue answered.
"I see..."
The dorm door remained cracked open slightly, making Kanon instinctively glance inside.
Logically, with such commotion outside, no matter what the person inside should come look. But this Yura-san seemed like she hadn't heard or simply didn't want to come out—showing absolutely no intention of appearing.
"By the way, does this mean you're also living at school now, Kanon?"
As if suddenly remembering something, Bokue asked.
"What about Natsuki..."
"Yes, that's right."
The silver-haired girl smiled and nodded.
"Previously, because of my internal spiritual circuit issues, Minamiya-sensei was responsible for observation and supervision. Now the observation period has ended. After confirming no rampage risk, Minamiya-sensei let me decide myself."
"I thought carefully. Though Minamiya-sensei's house is indeed very luxurious and large, considering that would trouble Minamiya-sensei too much, I moved back to the school dorm."
I see.
Though true, even though Natsuki Minamiya at first glance looked small—giving the impression she needed others' care—considering she already had Astarte as a full-time maid, Kanon indeed couldn't help much with daily life.
Moreover, living under someone else's roof didn't feel that great.
"If that's the case, from now on if you need anything at school, Kanon, you can message me. When I come I'll bring things for you along the way."
Bokue said.
"So are you heading to the cafeteria for dinner now, Kanon?"
"Yes, about to go."
"Alright then, you head over first. I still need to go upstairs to visit a senpai."
Bokue pointed upward.
"Okay, see you next time, Oniisan."
Though seeing Oniisan was indeed happy, since Bokue himself said he still needed to find someone else, Kanon didn't detain him much, smiling as she said goodbye.
So Bokue turned to leave.
Kanon remained in place. Not until the young man's figure disappeared at the stairwell did she withdraw her gaze.
Speaking of which...
Somehow, the silver-haired girl suddenly recalled the lubricant bottle that had rolled out from the door crack when her head bumped it earlier. Plus, seemed like Oniisan picked it up and took it along afterward.
Also, if her memory was correct, Kanon remembered seeing "adult" written on the bottle.
Though she was a good girl who'd never done anything improper, she understood that having those two characters generally meant something related to male-female matters.
But according to Oniisan's explanation, this was his sister's dorm. Oniisan definitely couldn't possibly do those things with his own sister.
Plus, that lubricant... what was it used for exactly?
Only vaguely knowing about male-female matters but never deeply understanding them, Kanon suddenly felt curious.
So she pulled out her phone from her skirt, opened the search bar, and typed in the product name and corresponding brand she'd just seen.
The next second, massive amounts of the same product from online shopping platforms leapt onto the screen.
Kanon randomly clicked one that looked similar, scrolling straight to the bottom description page.
But just scanning the text description once, the silver-haired girl's face instantly flushed red.
"An...al...!"
Forcibly suppressing the urge to cry out, Kanon rapidly covered her small mouth.
So... so Oniisan likes this kind of play?
Plus, that place can actually be used like that...
As if some new world's door had suddenly opened, spiraling mosquito coils began appearing in the silver-haired girl's eyes. Threads of white steam rose from atop her head.
Hiss—
Feeling her little brain about to overload, Kanon rapidly darkened the screen and put away her phone, then turned both hands over to press cool backs against her face.
No no no—can't keep looking. Still need to go to the cafeteria for dinner.
If she kept looking, probably couldn't even walk afterward.
Though...
The silver-haired girl who'd just been about to step forward and forcibly interrupt her thoughts suddenly stopped again.
If Oniisan really liked this kind of play, then she...
❁❁❁❁
Meanwhile, Bokue had already arrived upstairs at Saeko Busujima's dorm entrance.
Having been here once before, he knew the way.
Lightly knocking on the door—a few seconds later, as the dorm door slowly opened, dinner's food aroma wafted from inside.
Appearing at the entrance was the kendo girl wearing an apron.
Seeing the young man arrive, Saeko's face immediately showed gentle smile.
"I was just wondering when you would come. Perfect timing—I just finished making dinner. Hurry inside and eat."
"So Senpai personally cooked."
Bokue glanced behind the kendo girl. Could see dinner already set on the inner living room dining table.
Then he returned his gaze to Saeko.
"Though Senpai's outfit..."
As mentioned, Saeko wore an apron for cooking.
But the current problem was—Saeko wore only an apron!
The apron covered the front. An extremely thin waist strap tied in a knot directly around the kendo girl's tight waist, outlining that perfectly proportioned figure.
"Oh, this."
Saeko looked down at her outfit.
"Because I came straight back to the dorm after daily kendo club training. After showering still felt a bit hot, so I just made dinner in this state. After all, this is the girls' dorm—no other males would come."
"Plus, for Kohai, isn't this state more convenient?"
The final sentence seemed particularly meaningful. The kendo girl blinked.
"You have a point."
Bokue immediately expressed agreement with Senpai's words.
He stepped through the doorway, directly and unabashedly pulling Saeko into his embrace.
"Then let's eat while we start. Perfect timing—I brought what you requested before, Senpai."
"Mmm... w-wait, even if it's the girls' dorm... at least close the door first... kyaa~!?"
Definitely very convenient.
<><><><><><><><>
Time arrived at post-dinner.
As commotion inside the dorm completely settled, the wall clock's hour hand barely approached seven.
Of course, during these two hours, Bokue and Saeko hadn't only eaten dinner—they'd also conveniently showered and washed the dinner dishes together.
Body wash fragrance permeated the not-too-large bedroom. Having changed into pajamas, Saeko sat bedside, docilely turning her body to gently rest her head against the young man's chest beside her.
Actually, she hadn't needed another bath. After all, she'd already showered once after returning from club activities.
But since September weather remained sweltering, plus cooking in the kitchen required heat, plus during dinner they'd... well, anyway, better showering again before sleeping more comfortably tonight.
"Are you okay, Senpai? Didn't hurt as much today, right?"
Bokue looked down at the kendo girl in his embrace.
"I'm... fine..."
Not expecting the young man to bring up this topic so directly, Saeko's cheeks flushed slightly, but she still hummed softly.
Indeed, compared to last time, this time really didn't hurt much—could even say didn't hurt at all.
Even because of extra lubricant buff assistance, comfort far exceeded the first time. The direct result was her breaking through the clouds today doubling in frequency.
Hard to imagine this unconventional method working so much better than traditional approaches.
Originally just considering Bokue wanted it so reluctantly accommodating, but now Saeko felt she was almost falling in love with this method.
"Though... still feels slightly strange."
The kendo girl said quietly with flushed face while instinctively shifting her sitting position.
Bokue raised his tone in a hum.
"Strange how? Still uncomfortable after all?"
"No, not exactly..."
Saeko stammered, unable to articulate clearly herself.
"Just during the final moment in the bathroom earlier, maybe went slightly too hard. Feels like right now there's still somewhat..."
As she spoke, she unnaturally shifted position again, distributing body weight evenly centered.
Sure enough, slight residual sensation remained.
Like stubbing your pinky toe on a table leg—though after a while no longer hurts, you instinctively avoid putting weight on the pinky. Feels like bearing weight would still cause lingering pain.
Though what Saeko currently felt wasn't pain, the principle was the same.
Like that... was still there.
"Then maybe we shouldn't do it like that next time?"
Bokue scratched his face, feeling somewhat embarrassed.
"It's fine, really..."
Saeko shook her head with flushed face.
"As long as Kohai likes it, I'm okay with it. Plus, we already bought the stuff."
Bokue felt even more embarrassed: "But didn't you say you felt uncomfortable, Senpai? Plus, that bottle actually doesn't cost much."
"No, I'm not uncomfortable..."
Saeko had originally planned using the "already bought it" excuse out of girlish reserve. But seeing Bokue genuinely planning to abandon the new method considering her physical condition, she hastily denied.
"Just... mmm, probably because it's only the second time. Still not quite adapted, so the aftereffects feel slightly strong. Even now there's somewhat... anyway, I'm really not uncomfortable. Plus, you could tell, right? I actually quite like letting you..."
The kendo girl's voice inversely decreased as her facial temperature rose, becoming almost inaudible at the end.
After all, asking a girl to personally state she liked taking that route was somewhat too demanding.
But getting the meaning across was enough.
"Then if that's the case, how about I bring two large bottles next time?"
Bokue glanced at the plastic bottle on the nightstand—already down by a fifth.
Eh?
Hearing this, Saeko froze slightly before her cheeks rapidly flushed again.
Today's bottle had just been used—not even a small fraction. Calculating actual uses, at least four to five times remained.
Yet Bokue said he'd bring two large-capacity bottles later—meaning all intended for use here. Even possibly buying more in the future.
So from now on, Bokue would always go... mmm!
Forcibly suppressing surging anticipation and embarrassment from showing too obviously, Saeko lightly bit her lower lip and nodded slightly.
"Okay."
Completely unable to refuse.
As long as Bokue wanted it, how could she refuse?
Moreover, she'd actually already...
The kendo girl who thought she'd long recognized her own wicked nature couldn't help rare anticipation arising within when contemplating future life.
Just how far would Bokue lead her into depravity?
Just thinking about it made her want to drip, hehe~
❁❁❁❁
Like this, Bokue stayed in Saeko's dorm until nearly eight o'clock.
By this hour, the outside sky had completely darkened—precisely the starting point of a new day's nightlife.
Though for high schoolers with classes the next day, the nightlife starting point was precisely their time to wash up, relax, and prepare for rest.
"I'll head back then."
At the dorm entrance, Bokue's arms wrapped around the kendo girl who'd come to see him off.
"See you tomorrow, Senpai."
"Yeah, see you tomorrow."
Somewhat reluctantly standing on tiptoes to kiss the young man's lips, Saeko's azure eyes seemed to hold ocean waves lit by moonlight, layer upon layer pushing onto beaches.
"What would you like for dinner tomorrow?"
"Tomorrow... tomorrow might not work."
Bokue thought briefly.
"I see."
Though receiving the young man's refusal, Saeko didn't show displeasure.
After all, this was within expectations. She'd long known she wasn't the only one around Bokue. Yet even so, she'd still chosen to entrust both body and heart to him.
"Then next time when you're free."
The kendo girl smiled.
"Alright, I'm off then."
As Bokue spoke, he released his hands, pushing open the dorm door and stepping outside. Then accompanied by flashing golden radiance, his entire person vanished from the spot.
The door remained open. Saeko still stood in place, gazing at the now-empty dorm hallway outside as she took a light deep breath.
She'd originally considered that cohabiting with Bokue might bring unnecessary disputes for him.
Never expected that in the end, she'd instead troubled him.
Perhaps... she should find an opportunity to revise her decision.
