Kato Ayano had been in a foul mood for the past two or three days.

It wasn’t her period, yet she was inexplicably irritable, feeling an urge to snap at anyone and everyone. Was it because of the argument with her mother five days ago?

Or perhaps because she caught a cold afterward and couldn’t go anywhere?

Ayano herself didn’t know. She just felt restless, with no desire to go out. The only thing certain was that something was making her angry.

Even so, she was here now because her mother had been nagging her.

Since she’d stayed over for a night, her mother insisted she go thank them properly, even preparing a box of sweets for the occasion.

Ayano wanted to complain—what was the point of this now?—but seeing another argument on the horizon, she reluctantly followed her mother’s wishes this time.

“What’s up, Ayano? Running away from home again?”

Her childhood friend, Shuu, peeked through the gap in the door, tossing out a teasing remark.

A nearby potted plant rattled in the gusty wind, as if mocking her alongside Shuu.

Despite being far from winter, the air was unusually chilly.

Even though it was just next door, Ayano had to bundle up in a thick coat, and she’d briefly considered not going out at all. Of course, part of that was an excuse—she was still recovering from her illness.

The moment she pressed the doorbell and saw Shuu’s face, her body shivered involuntarily. She didn’t realize it wasn’t due to the cold.

“I’m here to thank you for letting me stay over the other day.”

With that, Ayano showed Shuu the package of sweets her mother had given her.

She knew her mother held Shuu in high regard.

He was a model student and someone she used to be close with.

Their parents, being neighbors, were also on good terms. Just before Shuu’s parents left for Hokkaido, they’d come over to ask her family to look after him. Until recently, her mother would jokingly ask if they were still not dating.

Ayano didn’t dislike Shuu, but as they grew up, she found herself increasingly frustrated with his personality.

In a word, he was too serious—boring. She’d realized he wasn’t the kind of guy who made her heart race.

(But last time we met, his vibe felt a little different…)

“Huh, didn’t know you’d become so considerate. Come on in.”

(That’s it—his way of talking has gotten more masculine.)

To Ayano, Shuu’s former polite speech had always felt weak.

It wasn’t that she liked crude, aggressive guys. But, growing up without a father, she subconsciously sought strength in men—someone to take charge.

That’s why, in high school, she started hanging out with bad influences like Sakaki and his crew.

“Nah, I just came to drop this off.”

“Is that so? Oh, perfect timing. I was thinking of splurging on some sushi, but they won’t deliver for just one person. If you haven’t eaten dinner yet, stick around.”

“I haven’t eaten, but… sushi? If it’s the cheap revolving kind, I’ll pass.”

“No promises it’ll suit your taste, but it’s high-end stuff. Pretty good.”

“Then I’ll stay.”

High-end delivery sushi should be decent, she figured, nodding. She loved sushi, and now that he mentioned it, she realized she was hungry.

Following Shuu’s back, she passed through the front door into the house.

The warm air from the heater felt comforting. Her body rejoiced at being freed from the cold. Despite her irritability up until now, being in Shuu’s house somehow made it fade.

“Sit wherever, grab what you want. I’ll get some tea.”

“Thanks.”

Ayano was surprised at how naturally she thanked him.

Since arriving, she felt oddly uplifted—almost happy.

That must be why the words came out so easily, she thought.

In the living room, a huge sushi bucket sat on the table.

Even for a growing guy like Shuu, it was far too much for one person. He’d said they wouldn’t deliver for one, but this looked like enough for three or four.

The idea that Shuu planned to eat this alone was more surprising.

Sitting on the sofa, Ayano picked up her favorite—uni—from the sushi bucket and popped it into her mouth.

“Whoa, this is good.”

“Told ya.”

Shuu returned with a guest teacup and offered it to her. Taking it, Ayano grabbed another piece of uni.

It was delicious.

She tried the eel sushi, made with half a fillet, and it was rich and tasty too.

“This must’ve been pricey, huh?”

“Guess so.”

“Celebrating something?”

“Not really. Lately, I’ve just been craving all sorts of good food. Been hitting up yakiniku places, ramen shops, tonkatsu joints—spending like crazy.”

“Wow, jealous. Living the rich life.”

What Ayano truly envied was Shuu’s freedom, with his parents away.

She didn’t hate her mother, but sometimes she couldn’t help wishing she wasn’t around.

Even as she felt guilty for such selfish thoughts, while eating the fancy sushi, she imagined being in Shuu’s position.

But at that moment, she noticed a slight unease in her body.

(What’s this feeling? My heart’s racing. And my lower half…)

A damp sensation spread between her legs.

Ayano realized her body was stirring with arousal.

(Oh, right, my ovulation’s coming up. I haven’t masturbated lately because I’ve been sick. Maybe I’ll do it when I get home.)

Ayano didn’t dislike masturbating.

She thought she might like it more than most, believing herself to be highly sexual.

Of course, she wanted to try sex.

But she also feared that once she did, she’d get hooked, like with masturbation.

Still, becoming a girl who casually sleeps around was beneath Kato Ayano’s pride—though she wouldn’t admit it.

She genuinely believed in the romantic notion of saving her virginity for someone she loved and would marry.

“Oh, Youkado’s pudding?”

The sweets her mother gave were puddings.

Leaving one out and putting the rest in the fridge, Shuu grabbed a spoon from the kitchen and started eating in front of her.

“Where’s mine?”

“Don’t have one.”

“What? There were plenty, weren’t there?”

“Saved the rest for later. Besides, these were a thank-you gift, right?”

“Don’t you usually offer some to guests?”

“Demanding guest, huh? Here.”

Grumbling softly about being handed half-eaten pudding, Ayano reluctantly started eating it.

And in that moment—

“Nn… ah, ah, ah!”

Her hips jolted involuntarily.

Ayano dropped the pudding with a soft thud.

Her body trembled in small spasms, her mind spinning wildly.

A molten sensation surged from deep within her womb.

She noticed her nipples, painfully hard inside her bra. Her entire body felt hypersensitive, the sensations overwhelming her brain.

Ayano had no idea what was happening.

But one thing was clear: a single emotion.

(It feels so good…)

She felt something forbidden gushing out from between her legs—maybe even urine mixed in.

She didn’t care about the shame. At a friend’s house, with someone who wasn’t even her boyfriend.

None of that mattered. The pleasure was overwhelming, a happiness she’d never felt in her life.

(Am I… climaxing?)

In her half-dazed mind, that was all she could grasp.

She didn’t know why. Or rather, the pleasure was so intense she couldn’t think about the cause.

Her body felt electrified, caressed, licked all over.

The sheer ecstasy made everything else irrelevant, and Ayano surrendered to it completely.

All she could do was pray the pleasure wouldn’t fade.

In the distance, she vaguely heard Shuu saying something.

“Hey, Ayano.”

She didn’t know how long she’d been like that.

The pleasure hadn’t fully subsided, lingering as an afterglow.

Regaining enough clarity to think, Ayano noticed the cold sensation between her legs and realized her skirt was slightly wet.

“Toilet!”

She rushed to the bathroom.

Inside, she pulled off her skirt, revealing an even worse state.

It was like she’d wet herself. Her panties were soaked, with faint yellowish stains of urine.

(What the hell is this?)

A flicker of anxiety surged, but it was quickly drowned out by the tingling pleasure from her groin.

She slid her panties down.

Immediately, Ayano understood the source of the sensation: her massively swollen clitoris.

It protruded from its hood, red and engorged. Below, her small vagina opened and closed, as if seeking food.

She’d always thought her clitoris was larger than average, but even during masturbation, it had never swollen this much. It pulsed, sending electric jolts of pleasure through her.

(If I touched it now…)

The thought crossed her mind.

The blissful feeling persisted, threatening to sweep away her rationality.

She wanted to touch her clitoris—now.

Like during masturbation, she wanted to rub it, slip a finger into her anus, and churn herself into a frenzy.

(How good would it feel to masturbate right now?)

Her mind was nearly consumed by the thought.

Any sensible notion of waiting until she got home had vanished.

She was so close.

“Ayano, you okay?”

If not for the knock at the door, she might have done it without shame or hesitation.

“Y-Yeah, just a stomachache.”

“Really? The sushi was fresh, so I doubt it’d upset your stomach that fast.”

“Probably something I ate at lunch.”

“Oh, got it.”

She wiped the wet areas with toilet paper, but it was far too messy to fix.

There was nothing she could do now. Confirming Shuu’s footsteps fading, Ayano cleaned up as best she could, put her panties and skirt back on, and left the bathroom.

“Sorry, I’m heading home. The sushi was great.”

She hurried through the hallway beside the living room.

Reaching the front door without Shuu noticing, Ayano felt a wave of relief.

The moment she opened the door, cold air rushed at her. The biting chill seemed to cool her overheated body.
