While Taking Care of My Shut-In Little Sister, I Somehow Ended Up Ejaculating Inside a Beautiful Girl - Chapter 40: Daily Life: Side Dish Swap Party

Chapter 40: Daily Life: Side Dish Swap Party

Ren, Yuu, Yakko, Nijouin, and Mizuno—five of us—are having lunch on the rooftop. As we open our bento boxes, a fragrant aroma wafts out. Analyzing the scents and visuals feels like glimpsing each person’s family and food philosophy—almost too much info for five bentos. Yuu made mine and hers, with different portions but the same menu, so I don’t need to overthink ours.

—Oh! Today’s main is katsuage! Nice!

Grateful for Yuu’s balanced bento—veggies, protein, carbs—I grab my chopsticks. My eyes catch everyone else’s lunches.

Yakko’s got her usual convenience store bento, no surprise. Mizuno’s bento is new to me—phew, it’s normal. In a good way. Her menu choices feel similar to Yuu’s, prioritizing balance.

—And then, the last one.

When my eyes land on her bento, I do a double-take.

(Nijouin’s bento… wow…)

Her bento is striking. First off, it’s in a fancy lacquered bento box.

It’s a single-tier box, probably to keep portions reasonable.

Nijouin carefully unwraps the furoshiki cloth and pops the lid off.

(Oh… this is…)

Beyond the lid lies a miniature paradise.

The food is arranged so meticulously, like a pro chef’s work, making the bento gleam. But on closer inspection, the contents are surprisingly normal.

First, a seafood section—shrimp and scallops—catches the eye. Then steamed chicken, carrots, spinach, and bean sprouts with sesame dressing. A Chikuzenni-like stew with chunky shiitake, lotus root, carrots, daikon, and fuki. The rice comes in three types—red bean, plain, and mixed—all in small portions for variety. A separate container holds desserts: sweet potato, kiwi, and grapefruit slices.

It’s labor-intensive, and the fancy box stands out, but it’s not ostentatious. No whole lobsters or anything absurd for an ojou-sama like Nijouin. The menu itself could be made in any household with enough time.

…It’s like she’s blending in with regular folks—no, that’s not quite right.

She’s an ojou-sama who understands regular folks.

Her possessions scream high-class, but she’s subtle, never flaunting, and her demeanor—while bold—doesn’t grate. It reinforces my hunch that she’s good at reading the room.

“…Hm?”

I notice I’m not the only one staring—everyone except Nijouin is peering at her bento.

“…Please don’t stare so much,” Nijouin says, looking more awkward than embarrassed.

Yakko, undeterred, jumps in. “Reiko-chan’s bento is more normal than I expected.”

“Of course,” Nijouin replies.

For a moment, I’m thrilled Yakko called her by her first name, but her next words send a chill down my spine. Yet Nijouin seems delighted by Yakko’s bluntness, which puts me at ease.

“Looks pretty tasty.”

“Doesn’t it?”

Nijouin puffs up slightly, making her two melons—er, her chest—jiggle. Oh, there’s an unexpected side dish—

“Ren-chan.”

“What?”

I’m focused on her bento, catching her chest’s movement in my peripheral vision, but Yuu—sharp as ever—immediately calls me out.

…How did she even know?

“You were looking, weren’t you?”

“Was not.”

Instinctively seeking calm amid this emotional rollercoaster, my eyes probably wandered to her chest. But honestly, seeing Nijouin’s dramatic jiggle doesn’t even stir me—my lower half stays quiet. What does that say about me as a guy? Yuu’s perfectly shaped and sized chest gets my engine going, but Nijouin’s? It’s like seeing a ghost or a UFO—just rare, not arousing. (Sorry, Nijouin, that’s rude of me.)

“…Ugh, Ren-chan, I know your tastes, but stop staring at other people’s,” Yuu says.

“Alright, my bad.”

I wasn’t staring, but I let it go to avoid a fight. Banishing Nijouin’s chest from my view, I mutter something about her “labor-intensive but relatable food” while eyeing her bento.

“Some think fancy food equals a rich meal, but balance—nutrition without excess or lack—is the true pinnacle. Our chef always says so,” Nijouin declares.

“Wow, so fancy. As expected of an ojou-sama,” Yakko says.

“Is that sarcasm?”

“No way~”

Yakko’s casually eyeing Nijouin’s bento, but it’s more like she can’t look away.

“—Oh! I see now. If you want some, just say so! Let’s swap side dishes! I’ve always wanted to try that!” Nijouin says gleefully, picking up on Yakko’s interest.

“Swap…? Mine’s just a convenience store bento,” Yakko hesitates.

“No matter! It’s about bonding as friends!” Nijouin insists.

“Weird taste,” Yakko mutters.

Unfazed by Yakko’s bluntness, Nijouin eagerly digs into Yakko’s bento, grabbing a piece of chicken katsu with her chopsticks and placing it in her box. Friend’s side dish: acquired.

“So, what do I get?” Yakko asks.

“Take whatever you like!”

“…Uh, um…”

“Nothing catches your eye?”

“It’s not that…”

Yakko, confident until now, falters when told to choose. Nijouin watches her warmly, almost like a mother and daughter.

“Why don’t we all swap?” Nijouin suggests to the group, likely to ease Yakko’s tension.

“Even me…?” Mizuno asks.

“No need to hold back, Mizuno-san. Let’s all trade one dish!” Nijouin says.

And so, Nijouin’s side dish swap party begins, turning our bento boxes into a chaotic mix.

This is wild! What a fresh event!

For someone like me with a small social circle, this is thrilling. Tasting everyone’s home cooking (well, minus two people) is amazing!

I glance at Yuu next to me.

“…Why that face? Ugh, Ren-chan, that’s not fair…” she sighs.

“Is it bad…?”

“…Fine. I really don’t want other people’s cooking in your body, but today’s special.”

“Thanks!”

Yuu’s words have a creepy edge, but with her permission, I join the swap, albeit a bit late.

Soon, my bento has Nijouin and Mizuno’s dishes. From Nijouin, I get shiitake and daikon from her Chikuzenni—flavorful and bold. I’m spoiled. In return, I give her an asparagus-wrapped meat roll. Mizuno’s bento is small, designed for lighter eaters compared to Yuu, so we swap a cherry tomato for a regular tomato. For some reason, she bursts out laughing.

—Now, one person left.

“Yakko-chan…”

“…!”

I’ve never seen a rabbit cornered by a lion, but somehow, Yakko’s trembling expression conjures that image. A nonexistent memory floods my mind: a wounded rabbit in tall grass, shaking but unable to look away from the lion.

“…Oh, right. You’re down to your last piece…”

I notice the issue with her lively-looking convenience store bento.

Right—her bento’s from a convenience store.

Her “capital” for swapping—her side dishes—is limited. Compared to Mizuno’s, she has more overall volume, mostly rice, but her side dish variety is unmatched in its scarcity. Her main is four pieces of chicken katsu, with shredded cabbage and a tiny bit of pickled daikon. Four pieces to work with in a big group swap? Impossible.

She’s guarding her last piece of chicken katsu like a vulture protecting a carcass.

If she wants to keep it, she’d have to trade the dishes she got from others with mine. Since I’ve already swapped with everyone else, I’d need her chicken katsu to complete the trade.

She couldn’t have predicted this event today.

“…!”

Tormented by guilt and torn over what to do, she’s too pitiful to watch. She bought a chicken katsu bento because she wanted it for lunch. She’s probably dying for at least one bite of that last piece. It’s not about being stingy—she’s endured this far, which is commendable.

She has other dishes now, but this morning—this moment—she needs that chicken katsu. That’s her truth. Unlike Mizuno, who cheerfully accepts the swap, Yakko’s mouth is set on katsu.

Am I really going to take her last piece—her final hope? Is that okay?

“Ren-chan, finish it quick,” Yuu says.

“Yako-san, if you want it that badly, I can give Hoshimiya-san—” Nijouin starts.

“Here I go,” I say.

““““—!?””””

I stab Yakko’s last chicken katsu with my chopsticks, and everyone gasps. Hold on, I’m not that heartless…

“Half, okay? We’ll split it. Half for my karaage… Hey, don’t cry!”

Yakko’s teary eyes light up.

Chicken katsu is thinner and wider than, say, tonkatsu, so splitting it feels less brutal.

…If this were a tonkatsu bento, I’d have chosen not to swap. Half a tonkatsu slice just looks like leftovers…

Not that chicken katsu is much better. Just slightly less tragic.

“Itadakimasu—”

I manage to cut Yakko’s last chicken katsu piece in half with my chopsticks, placing it in my bento and giving her one of my karaage in return.

“Ren-kun…” Yakko’s eyes glisten with gratitude.

“Heh.” I rub under my nose, a bit embarrassed.

We’re both acting weirdly hyped, but it’s just us vibing.

—That said.

Someone’s not happy with our exchange.

“…Ren-chan. I did allow the side dish swap,” Yuu says.

“Yeah?”

My girlfriend, Yuu, is glaring.

“…You knew what you were doing, didn’t you?”

“Nope! No clue what you mean!” I surrender, genuinely confused.

Yuu’s radiating an invisible pressure, zmoooom, and she’s clearly pissed. I don’t know why, but the reason becomes obvious soon enough.

“…Now all the karaage is gone.”

“Oh, crap, you’re right.”

My bento’s a colorful chaos now, but the main event—Yuu’s special karaage, made just for me—is missing. Big, hearty, love-filled pieces crafted for a guy’s appetite. Gone.

“I made those for you…” Yuu sighs dramatically, lowering her chopsticks to the bento’s edge.

Normally, I’d panic—I messed up her mood, what do I do?—but there’s no need.

The hint—no, the answer—is right there in her actions.

“Yuu, sorry. Since the karaage’s gone—” I grab her hand.

She looks surprised but doesn’t let go of the half-eaten karaage pinched in her chopsticks.

…Okay, I’m not big on public “aah” feeding moments. Yuu usually avoids embarrassing stuff too, but when her rationality brakes fail, it’s a different story. She loses all hesitation for public displays of affection.

Right now, unlike her, I’m feeling intense embarrassment.

—Which is why.

To think I’d pull this off, here, on the spot.

Yuu, you cunning strategist!

“…I’ll take a bite.”

“No way! ♥ Ren-chan, you… ♥”

I guide her hand to my mouth. The karaage, firmly gripped by her chopsticks, doesn’t budge an inch. As expected, when it reaches my open mouth, her grip loosens. The chopsticks brush my lips, and the crispy karaage lands on my tongue.

Self-serve “aah.”

…What is this?

“God! ♥ Indirect kiss in public… ♥ So greedy! ♥♥”

I chew the karaage, ignoring Yuu’s teasing. Damn, this is good. As always, Yuu’s cooking warms my heart and soul.

“That was so cute, Ren-chan! ♥ Like a squirrel! No, cuter! ♥ Can I take a pic? ♥ Oh, I already am! ♥”

She’s snapping photos with her silent phone, not even hiding it like she does on dates. Fine, whatever. Just let me eat this delicious food in peace…

The three others—Nijouin, Yakko, and Mizuno—stare at us with mixed reactions.

“…”

“…Flirting here? Seriously…” Yakko mutters, her expression sour.

“Ugh… I need to get better at cooking…” Mizuno sighs heavily.

“Again with the usual?” Nijouin sighs lightly, sipping tea from her thermos with a composed air. “It’s lovely that you two are so close, though.”

“I’m jealous… Someday, with Sorimachi-kun…” Mizuno trails off, gazing into her future, popping a cherry tomato in her mouth. “Gotta make him notice me first…”

Each has their own take, but Yuu doesn’t care.

“Here! ♥ Veggies next! Aah! ♥”

“Uh… aah…”

And just like that, I’m roped into an “aah” feeding shame-play.

Yuu scores a technical win. In this impromptu showdown, I’m completely defeated.

“Y-Yuu, enough. I’ll eat on my own…”

“Nope! ♥ Open wide! Aah! ♥”

“Uh, well…”

“Aah! ♥”

“A-Aah…”

Even the other rooftop couples start staring. By the end of lunch break, we’re the center of curious gazes.
