Chapter 78: She must be hiding something, my sister who loves to mess around with other women

“Sister, where are you now? Why did I come back and find you missing?”

Gui Yue’s voice came through the phone as I looked at Ning Xueyang, who kept shaking her head, quietly pleading with her.

“No, don’t…! My little sister is listening, you know…”

But Ning Xueyang didn’t pay much attention to my plea. Her hands continued their practiced movements on my body.

My body was completely powerless, utterly unable to resist. Ugh, ugh…

After a while, Ning Xueyang looked at me with a mischievous smile and slowly spoke.

“Oh my~ You’re begging me to stop with your mouth, but your body has been honestly responding all along~”

“I… I didn’t!”

Blushing, I protested, but Ning Xueyang pulled her hand away at that moment and showed me the silver thread at her fingertips.

“Then, Teacher, care to explain what this is?”

“PS…!”

Not knowing how to respond, I lowered my flushed face and pressed my body against the toilet tank.

Why is this happening… ugh, ugh…

At the same time, Gui Yue’s voice came through the phone again.

“Sister? Where are you? Why did you answer but not say anything?”

Hearing Gui Yue’s anxious voice, I hurriedly replied.

“I’m here! Gui Yue, I… ugh~”

Before I could finish, Ning Xueyang suddenly got mischievous again. My unguarded body trembled under her tentative assault.

An enticing moan slipped out from my lips without my noticing. Luckily, I restrained myself in time; otherwise, things would have gotten even worse.

“Sister?”

Gui Yue’s confused voice came through the phone, clearly sensing something was wrong.

“N-Nothing! I just… just… ugh~”

Taking advantage of my hesitation, Ning Xueyang launched another verbal assault.

The intense sensation interrupted my words again, forcing me to reorganize my thoughts.

“I was just… in the bathroom and accidentally made a noise.”

That wasn’t exactly true. Though I came here to use the bathroom, under Ning Xueyang’s gaze, I couldn’t let go of my shame and could only hold it in.

Ugh, I can’t let it out in front of Ning Xueyang. I have to hold it in no matter what!

Gritting my teeth, I gathered the little strength I had left to control my bladder.

I endured with all my might. Ning Xueyang’s attacks became even more intense, and she didn’t forget to use those devilish words to try and break down my last defense.

“Come on~ Teacher, just relax and let it out comfortably~ No need to hold back anymore~”

My rational mind told me not to listen to Ning Xueyang. If I gave in here, little sister Gui Yue would hear everything.

But her words seemed to carry some strange magic, making me want to relax despite myself.

“Sister, what’s wrong with you? Why do you sound weird?”

Gui Yue’s voice came again, pulling my scattered mind back together.

“N-Nothing, it’s just… haah~ just using the bathroom. I’ll be back soon.”

Gui Yue hesitated for a moment before answering. I knew she had definitely sensed something.

“Oh, then hurry up.”

“Yeah, so… haah~ that’s it, I’m gonna…”

Before I could finish, Ning Xueyang suddenly intensified her assault again.

After holding out for so long, my dam finally broke, two streams pouring out one after another—

First, a tidal wave engulfing everything, then a gentle mountain brook.

The pleasure from releasing twice in a row left me utterly unable to think, like a life-sized doll dumbly draped over the tank.

In my dazed state, I vaguely heard Gui Yue’s anxious voice coming from the phone.

“Sister? Sister! What’s wrong with you?”

Still caught in the aftershocks, I couldn’t answer her, only staring blankly at the phone with a foolish smile.

Ning Xueyang chuckled lightly and gently stroked my body with her palm.

The soft touch of her hand made me close my eyes, feeling the warmth and softness while savoring the lingering sensation.

But soon, provoked by her words, I regained my composure.

I wiped off my expression of pleasure and glared at Ning Xueyang, biting my lip.

“Ugh, how can you be doing this while I’m on the phone with my sister?!”

Ning Xueyang said nothing, her face still wearing a sly smile.

Meanwhile, little sister had been asking non-stop from the other end.

“Sis, answer me, will you?”

“Oh, just now—just now, Sister saw a cockroach, got scared and screamed, then was too busy chasing it away to answer you.”

“Oh, it’s okay then.”

“Okay, I’m hanging up first. I’ll come find you soon.”

“Yeah, Sister, hurry back…”

After hanging up, I looked at Ning Xueyang with a flushed face, filled with shame and anger.

“You bad, bad, bad! You’re so bad, ugh ugh ugh!”

Looking at the “masterpiece” I had just made, I even wanted to kill Ning Xueyang now.

“Ugh, ugh, do you even realize what you did? I was on the phone with Gui Yue just now! Luckily, I fooled her, or else… ugh ugh ugh…”

At this moment, I had completely lost the dignity I usually had as a teacher. I was like a little girl throwing a tantrum at Ning Xueyang, punching her wildly with my little fists.

But I was so weak, and after going through what I did, my body had no strength left. No matter how much I punched, I couldn’t cause any damage, and Ning Xueyang easily restrained my arms.

She adjusted my position slightly, turning me to face her, then gently stroked my head.

“Don’t touch me! Don’t you dare touch my head! Bad person!!!”

Seeing me resist, Ning Xueyang smiled mischievously again.

“Since Teacher thinks I’m a bad person, should I do that thing to you again?”

“Ugh! No, please don’t!!!!”

Hearing that, I trembled all over. I absolutely didn’t want to go through that again—two liquids pouring out one after the other…

“Am I still a bad person now?” Ning Xueyang squinted with a smile, her eyes locked on me.

Facing her threat, I knew very well that if I didn’t give in here, with how perverse she was, she might really do the same thing to me again.

So, I could only compromise and avoid conflict.

“Ugh, then you’re not a bad person anymore…”

Ugh ugh ugh, first she does that to me, then won’t even let me say she’s a bad person. Isn’t that bullying?

Seeing this, Ning Xueyang showed a satisfied smile.

“When Teacher’s strength recovers, I’ll leave~”

After hanging up, Gui Yue frowned deeply, her face heavy as she stared at her phone.

“She’s definitely hiding something. My sister who’s always flirting around~”
