“Big Sis Feng, what about this one?”

Xi Xi pointed at the screen. On it was a slender woman in a black uniform, sitting in a duck-sit pose. Ropes bound her body, accentuating every curve. A black cloth covered her eyes. Something was stuffed in her mouth. Her whole face was flushed, and a trace of clear drool slipped from the corner of her lips.

Xi Kefeng shook her head. In her calm eyes, there was only confusion.

“Doesn’t sitting like that feel uncomfortable?”

“...”

Xi Xi fell silent for a moment, then gritted her teeth.

“I refuse to believe there isn’t a single picture that can make you blush. Next one!”

The image switched instantly.

This time, it was a top-down angle. A girl in a student uniform was kneeling on the floor, gazing at the camera with watery eyes, silently pleading.

This picture wasn’t as explicit as the last one. You could even say it was almost normal. But the difference was that around her snow-white neck was a dark red collar, extending upward and out of frame, as if something was holding her on a leash.

“This student... what’s going on with her?” Xi Kefeng asked in confusion.

She thought of Qiu Li'er from this morning. Back then, she had seemed to be begging her in much the same way.

“Hehe~ Big Sis Feng, just like I thought, you don’t get it.”

Xi Xi smugly shook her shoulders and pointed at the girl’s pale neck.

“See that silver tag on the collar? Big Sis Feng, read what it says.”

“‘Little puppy was adopted on June 6.’”

“Now you get it, right~ Big Sis Feng? That kind of wording usually only appears on pet tags.”

Xi Xi leaned close to Xi Kefeng’s ear and whispered softly,

“So then, what kind of relationship do you think the girl and the person taking the photo have?”

“Mmh...”

The pupils that had been calm as still water rippled soundlessly.

Xi Kefeng lowered her head slightly and looked at her own feet. In her mind appeared the image of Qiu Li'er, face full of pleading, hugging her feet.

Then she awkwardly drew her feet up a little. A few faint streaks of red crept onto the tips of her ears.

“Is it... a pet and owner relationship?”

“Correct~ A collar is a sign that one person has completely submitted to another. Looks like you don’t know nothing after all, Big Sis Feng.”

Xi Xi smiled as she spoke. She didn’t notice her sister’s unnatural reaction, and casually opened another image.

Her mindset had already changed. At first, when her family found out, she had been mortified. But now it was more like, “Here, let me introduce my treasured collection from the past few years.”

Rather than giving up in embarrassment, she was practically itching to show it off.

“Big Sis Feng, look at the next one~”

This picture also looked pretty normal. Two girls were lying on a bed. One was flat on her back, while the other was on top of her, propped up on her arms as they stared into each other’s eyes. Their faces were so close they were almost touching.

“This one doesn’t seem like much...”

“Big Sis Feng, did you notice?” Xi Xi said excitedly. “The two of them look really alike!”

“Mmh...”

Her little sister’s words made Xi Kefeng realize it too.

The two girls in the picture really did look extremely similar. Their features seemed carved from the same mold. Only their expressions were different. The one pinned beneath wore a face full of shy embarrassment, while the one on top had a faint smile...

Suddenly, Xi Kefeng glanced at Xi Xi, who was right beside her. Then she slowly turned her head away.

She realized her cheeks were starting to feel a little warm. She wanted to hide the blush on her face from her little sister.

Her heart was beating fast.

“They... are they twin sisters?”

“Yep! A pair of sisters related by blood!”

Xi Xi didn’t look at her sister. She kept staring at the screen as she spoke excitedly.

“And in this picture, the younger sister has already pinned the older sister onto the bed and is about to start exercising!”

“Exercising?” Xi Kefeng asked, puzzled. “What kind of exercise? Sit-ups?”

“Oh, come on~ Big Sis Feng, you’re already this old and you still don’t know this stuff?”

Xi Xi covered her mouth and snickered.

“Exercise means—smack, smack, smack!”

“Oh, clapping.”

Xi Kefeng opened her mouth slightly.

“An exercise for the palms. It helps keep the sword hilt from slipping out of your hand.”

“Tch, clapping, clapping—what clapping?”

Xi Xi looked like she was exasperated beyond words.

“I mean clapping for love!”

“I don’t understand.” Xi Kefeng shook her head. “Is that some kind of riddle?”

She vaguely felt like she understood. And yet, she also didn’t.

“Forget it, I’ll explain it in a simple way.”

Xi Xi quickly zoomed in on the image and began explaining patiently.

“After pinning her down, the younger sister might start from the collarbone here. Or she might pull open the clothes and go lower. That depends on personal preference. And at that point, the older sister will blush, talk, and put up some useless resistance... but in the end, her hands will definitely honestly hook around her little sister’s neck.”

“W-Why?”

“Because the younger sister will kiss her all the way up. From the collarbone to the neck, then to her lips. In the end, their lips will press together.”

Xi Xi spoke with great satisfaction, completely unaware that her sister’s cheeks were getting redder and redder.

“Wait...” Xi Kefeng said in a low voice.

“While they’re kissing, the older sister will unconsciously hold the younger one. She might even wrap both legs around her waist. But the younger sister’s hands definitely won’t stay idle. She’ll slide them along the inside of her older sister’s thighs...”

“Stop talking...”

“In a closed private room, a forbidden romance between sisters, desire surging beneath those pure school uniforms—”

“That’s enough!”

Xi Kefeng suddenly stood up.

Xi Xi jumped at the shout. Her flaxen hair fell over her vision, and she couldn’t see her sister’s face clearly.

Uh... Big Sis Feng isn’t angry, is she?

Oh no, oh no, oh no. This time, even kneeling down and begging probably won’t help. I really shouldn’t have gone this far.

But still...

The feeling of introducing all these lewd pictures in one go—

It was seriously amazing.

Xi Xi closed her eyes in satisfaction, ready to receive the scolding that was about to come.

“That’s enough for today.”

Unexpectedly, Xi Kefeng only said that lightly. Then, just as usual, she turned and left with graceful steps.

On the surface, she looked no different from normal. But her usually serene face was now so red it looked ready to drip blood. In twenty-five years, she had never felt anything like this before.

Tonight, the story Xi Xi had told would surely take root in her heart. Then it would grow wildly like weeds, filling that tranquil lake inside her that had once been as still and clear as a mirror.

Watching her sister’s departing back, Xi Xi scratched her little head, not understanding what had just happened.

Honestly, it was pretty sudden.

“Was Big Sis Feng angry?” Xi Xi muttered in confusion. Then she subconsciously glanced at her palm. “Crap, I lost two more hairs. Looks like I really need to stop staying up so late.”

She looked back at the magic web screen.

That taboo-like sisterly romance, forbidden to most people, happened to hit her tastes perfectly. That was why she had saved the picture in her collection.

“Ahh~ Younger-sister domination between sisters is the best~”

Xi Xi contentedly closed the album and muttered to herself,

“Should I show this album to Xiao Shi too?”

“She’d probably like it too, right? Hmm... maybe not. That idiot probably wouldn’t understand my art. But I can at least talk to her about this kind of stuff first.”

Only right before bed did she finally notice the message Qiu Li'er had sent her.

By then, Qiu Li'er was already asleep.
