The Secret Desire for a Bottom Spanking

I, Yuuki, have a secret dream. It is to be taken over the soft lap of my beloved older sister, Misaki, and given a “punishment.”

My older sister is a high school student, and she is always kind and beautiful. Every time her silky black hair sways, the sweet scent of her shampoo drifts softly through the air. If I bragged about her to my friends at school, surely everyone would be jealous. But even my seemingly perfect sister has one strict side. That is when I do something bad.

When I was still little, I once scribbled on the living room wall with crayons. Back then, after scolding me, my sister laid me face-down over her lap and lightly spanked my bottom over my pajamas. She said, “Bad children get a spanking.” It did not really hurt, but the feel of her warm palm and the strange sense of comfort—being scolded yet somehow wrapped up in warmth—was burned deeply into my heart.

That memory eventually grew inside me into a distorted desire.

“If I do something bad, I’ll be laid face-down over my sister’s soft lap and forced into a position where my bottom is sticking out. Then my underwear will be slowly pulled down, and my bare bottom will be spanked hard with her warm palm until I scream and cry.”

That fantasy crossed my mind again and again in bed before sleep. It was supposed to be a punishment, yet to me it felt like the greatest expression of love. I wanted my sister to discipline my “bad bottom” with her warm hand. I wanted to feel her warmth and strictness with my whole body.

“……All right, I’ve decided.”

Today, I would make that dream real. I jumped out of bed and began plotting. A simple prank would not do. It had to be effective enough that my sister would truly think, “I have to punish him,” yet not so bad that it could never be undone—an exquisite line to walk.

I looked around my room. On the desk was an antique fountain pen that my sister treasured. It was a memento of our late grandfather, and sometimes my sister would gaze at it, refill its ink, and pretend to write letters. If I used that, my sister would surely be truly troubled.

I secretly slipped into my sister’s room. She was still not home from club activities. When I picked up the fountain pen on the desk, a heavy weight spread through my hand. I carried it back to my room and hid it in the very back of my study desk, where no one would find it.

My heart pounded. This was a bad thing. But when I thought of the sweet punishment waiting ahead, anticipation beat guilt. Why would my sister not come home sooner? From my room’s window, I kept waiting for my sister to come home, impatiently, endlessly.

As the evening chime rang out, the sound of the front door opening came.

“I’m home.”

It was my sister’s cheerful voice. I pretended to be calm and headed to the living room. “Welcome back, sis,” I said, and my sister smiled gently. “I’m home, Yuuki.” Every time I saw that smile, my chest ached a little. But I could no longer turn back.

After changing out of her uniform into loungewear, my sister seemed to start her homework in her room. After a while, when she came out, confusion was written on her face.

“Yuuki, do you know? The fountain pen I left on my desk.”

It came. I cheered inside.

“Huh? Fountain pen? I don’t know.”

I deliberately answered while keeping my eyes on the TV. My sister furrowed her brows and stared at me as if suspicious of my attitude.

“I see…… where could it have gone? It was Grandpa’s memento, so I’d be in trouble if it disappeared.”

Saying that, my sister began searching the house again. The living room, the kitchen, her own room. Watching her search everywhere, guilt raised its head again. But if I confessed now, everything would be ruined.

About thirty minutes must have passed. My sister, completely tired of searching, plopped down on the sofa. Then she stared fixedly at my face. Under that serious gaze, I swallowed hard.

“Yuuki.” “……What?” “You know something, don’t you?”

She had hit the mark. But I kept playing dumb.

“I told you I don’t know.” “Liar. I can tell just by looking at your eyes. You like pranks, and sometimes you do things like this, don’t you? Tell me honestly. Where did you hide it?”

Anger gradually began to mix into my sister’s voice. I thought this was my chance. As if to provoke her, I lifted one corner of my mouth slightly and smiled.

“Who knows? Do you have any proof I hid it?”

In that instant, my sister’s expression changed. The face of my kind sister disappeared, and the face of a strict disciplinarian appeared. The face I had wanted to see all along.

“Yuuki. That’s enough.”

My sister stood up smoothly and grabbed my arm firmly. The strength was greater than I expected, and my heart jumped.

“If you won’t tell the truth, then it seems you need a punishment. Bad children won’t understand unless their bottoms get a spanking.”

The moment I heard those words, joy like an electric current ran through my whole body. The moment I had waited for. The punishment I had seen even in my dreams. My sister pulled my hand hard and led me to the large sofa in the center of the living room. My heart pounded so violently it felt as if it would burst.

Standing before the sofa, I faced my sister. She looked into my eyes and quietly, yet with an unyielding strength that allowed no objection, declared:

“Lie face-down over your sister’s lap.”

I did as I was told, placed both hands on the sofa seat, and slowly tipped my body forward. Naturally, my bottom stuck out. Shame and anticipation made my face burn hot.

Then my sister slowly drew my body onto her lap. A soft, fluffy warmth reached me around the stomach. The gentle feel of my sister’s loungewear and the faint scent of fabric softener. It was the special seat I had dreamed of.

“Yuuki. Where is the fountain pen?”

As if giving me one last chance, my sister whispered by my ear. But I still shook my head. I could not let it end here.

“……I don’t know.”

When I answered that way, my sister gave a deep sigh.

“I see. Then I suppose I’ll have to ask your bad bottom.”

With those words, my sister’s fingers hooked onto the waistband of my pants. Then, slowly, hesitantly, my pants and underwear were pulled down together. Cool air touched my defenseless skin. My fully exposed bottom was lit by the living room light. Shame made even my ears bright red.

My sister said nothing and gently stroked my white bottom with her warm palm. It was like a quiet caress before a ritual about to begin. And then, the next instant.

Smack!

A dry sound echoed, and a hot impact ran through my bottom. I unintentionally let out a “Hic!” It hurt. Far more than I had imagined. But at the same time, a tingling pleasure raced up my spine.

“What do you think? Does this help you remember?”

Smack! Smack!

In rapid succession, rhythmic slaps landed. My sister’s palm was warm and soft, yet the instant it struck, it was like burning iron. Heat and pain spread in pulses from where I was hit.

“S-Sorry……” “What are you apologizing for? You haven’t done anything, have you?”

My sister’s voice was calm. That only cornered me further. My bottom grew hotter and hotter, and every time I was spanked, my body jerked.

Smack! Smack!

“Ugh… ahh……!”

Tears spilled out one after another, staining the sofa fabric. Pain, shame, and the feeling of being filled up all mixed together, and my head went blank.

Smack! Smack! Smack!

As the number of spanks increased, my endurance reached its limit.

“I’m sorry! I’m sorry, sis! I hid it!”

At last I confessed while crying out. My sister only said coldly, “I see,” and the bottom-spanking did not stop. A punishment that would not forgive me even if I cried. The fear that the pain in my bottom would never end. To the strict bottom-spanking I had seen in my dreams, I kept crying as if utterly intoxicated.

Smack! Smack! Smack!

“Hic—!?”

A violent three-strike barrage, as if my bottom would break, slammed down, and the pain was so intense I could not even cry out; my breath caught. By the time my bottom was swollen tight and the heat and stinging would not stop, the slaps suddenly stopped cleanly. My sister stopped spanking and this time gently stroked my bright red bottom as if comforting it. Because that kindness was so overwhelming, I cried even louder.

“Waaah……!”

The punishment was over. Strict, painful, yet filled to the very end with love—my very own punishment. My bottom hurt and burned unbearably, but I was filled with a feeling of deep satisfaction. While crying, I entrusted my bottom to my sister’s gentle, stroking hand.

For a while, I sobbed on my sister’s lap. My sister silently stroked my bottom gently. The way she touched my heated bottom was as if she were handling something fragile, endlessly kind.

“……Come now, stop crying.”

Eventually my sister said that and gently pulled up my underwear and pants. Then she raised me up, sat me on the sofa, and sat down beside me herself.

“Where is the fountain pen?” “……The very back of my desk drawer……”

I answered while hiccupping. My sister only said, “I see,” and wiped my tear-wet cheek with her finger.

“Why did you do this? You knew how important that was, didn’t you?”

There was no anger in her voice anymore, only a sad ring. I could not possibly say the real reason, so I hung my head and fell silent.

“Did you want your sister to punish you?”

At my sister’s words, I raised my head with a start. She smiled calmly, as if she had seen through everything.

“……Yeah.”

I gave a small nod. I see—so my sister had known, and had punished me strictly just as I wished. I felt a touch of embarrassment, and my chest grew hot at my sister’s consideration.

“I see.”

My sister gently patted my head.

“But you mustn’t do it this way anymore. I was worried. If you want your sister to spank your bottom, then say it properly in words. All right?” “……Yeah. I’m sorry.” “Good. That’s my good boy.”

Saying that, my sister hugged me tightly. Wrapped in my sister’s embrace, the sweet scent of her shampoo and her warm body heat reassured me. Even the stinging heat of my bottom now felt like proof of my sister’s love.

My dream had come true. It was far more painful and far more embarrassing than my fantasy, but in the end, something so warm was waiting for me.

As long as this warmth exists, I am sure I will be all right. But perhaps someday, I might once again beg for this sweet and strict punishment. While thinking such things in my sister’s arms, I quietly closed my eyes.
