Faced with my cute sister’s question, staying silent wasn’t an option. I had to face her beaming smile, but I worried she’d ask for something outrageous—like making me fly. I just couldn’t do that... Fine, I’d bite the bullet. "Yeah, I said that. But Xiao Ling, don’t ask for anything too extreme, okay?"

Oh no! What was I saying? Was I giving my sister hints? It sounded like I wouldn’t refuse any normal outrageous requests. Was I tempting my dear sister...?

"Bro, now that you mention it... I’m actually a bit tempted. But why would I ask you for anything outrageous? (Idiot brother, what do you think I’ll do to you? Can you even resist me now!) I’m your sister, after all."

My sister suddenly became so well-behaved, but I couldn’t shake the feeling her smile made me seem like prey already caught. What was this déjà vu? Better ask directly.

"So, Xiao Ling, is there anything you need help with?"

"Of course! Bro, you looked so smug and relaxed outside the door just now, didn’t you?"

"Heh heh, not at all. I just saw you were tired from writing, so I called you out to rest and keep Miko company." I forced an explanation, hoping to move past this.

"Oh, really? Whatever, it doesn’t matter. Bro, I’m handing all my homework to you. Don’t back out! I’ll listen and go watch TV with Miko!" Xiao Ling pulled assignments from her backpack, dumped them onto my lap, gave my cheek a playful pat, then skipped out. I was left alone on the bed, staring at the heavy stack of exercise books.

"Don’t forget the ones on the desk too~" Her cheerful voice called from outside.

"Got it..."

With a bitter smile, I sat at her desk, copying familiar exercises and words. What have I done? Did I need more chaos? Might as well treat it as early review. Maybe I came here to help her—I might need her help later as her brother.

Like today on the stairs—if Xiao Ling hadn’t pulled me up, I’d be in the hospital. So I should help where I can. Pfft! I’m just making excuses for my own stupidity. Ugh, why am I ranting to myself again? So annoying!

... ...

*Phew* Finally done. Rusty after ages without middle school problems. Must break my habit of crossing arms when thinking. Now that my chest is so... full, I forget everything and just think (So soft~ I want to squeeze~). Then I squeeze, wasting ten minutes on that weird feeling. Hmm, pitch dark outside—checked the clock: 23:20. Three hours straight! Do middle schoolers really have this much weekend homework?! Never felt this tired before. Sigh, must be this new dumb brain. Wonder how dumb the original owner was. Hahaha.

(Hua Shu! Hmph!)

*Squeak~*

Huh? Why’s my chair so slippery?

*Thud!*

Ouch! Damn! The chair slid back—I nearly died! I grabbed the bed leg, stood slowly. Hallucinating from homework? Probably... That really hurts.

"Bro! What happened? What was that noise?" Xiao Ling shouted.

"Nothing... Just celebrating finishing homework!" *I’m such an idiot, really.*

I walked out. Even on Sunday, they shouldn’t stay up late—it’s bad for health. In the living room, Miko and Xiao Ling leaned together, eating nuts and watching TV. Tsk, such a cozy scene... if only Xiao Ling wasn’t pressing her crotch with one hand, face flushed red. Wait, why’s she blushing at Miko? That’s dangerous for Miko!

"Miko, it’s late. Go rest. Xiao Ling, stop eating!"

"Oh~ That late, Hua Shu? Time for bed."

"Bro, you took so long? And you’re a high schooler?"

"Who knew you had so much homework! My hand cramped before finishing."

"You finished all of it?!"

"Of course! Otherwise it wouldn’t be done. Wait, don’t tell me..."

"Pffft, haha! No homework next week! Yay~ Bro, you’re the best!"

Tears welled up realizing the truth... I wasn’t dumber—I was tricked by my sister. So sorry for this brain’s original owner. On Xiao Ling’s behalf, deepest apologies!

(Hmph!)

"Heh... Let’s sleep." I headed to my room.

"Okay, Xiao Ling, let’s go too!"

"Mhm!"

Well, such an obedient sister~ Wait, sister!?

"Wait!"

"What is it, Hua Shu?" Miko looked puzzled.

"Um, you sleep in my room tonight. I need to talk to Xiao Ling about school."

"What can’t wait until tomorrow, Hua Shu?"

"Anyway... just go sleep. School stuff."

"Huh?" x2

I couldn’t let Xiao Ling, with that weird expression, share a bed with Miko. Tomorrow she might grab both our hands and say: "Bro! Miko’s mine too now. Get along, okay~" I’d faint. So I took Xiao Ling’s hand and said goodnight to Miko.

But in her room, I froze. We hadn’t slept together since she was six. Should I strip naked like in my room?

"Bro, hurry up and change into pajamas!" Xiao Ling reminded.

"Uh, I’ll sleep on the couch!" I grabbed a blanket to leave.

"Bro, do you hate who I am now?" She asked softly, head down.

"How could I? You’re still my dear Xiao Ling. Silly kid, stop overthinking."

"Really...?"

"Of course. Couch is to avoid disturbing you. Heh heh."

"Then lie down properly! You jerk, Hua Shu!"

Huh? Her attitude flipped—no "bro" anymore. Hey! What are you grabbing? Ouch! Threw me on the bed again. Sister, you really... Ugh, covered my head with something.

"This is the pajamas from that busty woman’s package. Change and sleep. Forget it—I’ll do it." She pushed me down, untying my ribbons, unhooking my bra, slowly rolling down my stockings...

"I don’t need to help you put it on, right, Onii-chan~?"

I didn’t know what to say. Tell her to stop? These clothes were tricky. Accuse her of disrespect? Hmm.

"Fine! I’ll do it myself." Words came out wrong. Her serious face—who was the older sibling? Sister, why a sheer nightgown? Not regular pajamas...

"Lie down, Xiao Ling. Turn off the light~" After changing, her gaze heated up. I changed subject fast. Ugh, is she a boy in disguise? Acting so lewd.

"Oh, I’ll turn it off after changing." She slowly peeled off her dress and leggings. Look or not... To see her changes clearly, I decided: look! Carefully!

Xiao Ling, seeing me stare, didn’t blush. She smiled, removed her underwear, revealing plump, jelly-like breasts and a slender frame. Only my boxers ruined it. Sensing my gaze, she slowly peeled those off too...

Just as I leaned in—*snap!*—light off. Heh, missed what I wanted, saw what I shouldn’t. Beastly brother... But what came next made me stop feeling like one.

She put on a nightgown, covered me with her blanket too. Tsk, good sister. Then she crawled in, hugged me tight, pressed her little bunnies to my chest. Baby bunnies seeking mom? I didn’t dare move, just stared wide-eyed, hoping she’d sleep.

But she slid her right leg between mine, hugging tighter. Her closeness made my long-lost little brother nuzzle my lower abdomen through the nightgown, "crying" from emotion. Truly my brother...
