My Ex-Girlfriend’s Sister Ran Away to My Room, and We Can’t Stop Making Mistakes. - Chapter 8: Chuuka Sei Zanmai.

Chuuka Sei Zanmai.

After my shift ended, I didn’t head for the station. Instead, I walked toward the heart of the entertainment district.

The shop Vanilla had recommended was tucked inside a multi-tenant building crowded with girls’ bars and adult establishments.

The name was Chuuka Sei Zanmai—Chinese Carnal Samadhi. As I stepped off the elevator, I was greeted by a gaudy signboard decorated with an ornate golden dragon.

Vanilla had told me they’d know who I was if I gave my name. I sat in the waiting room for only a moment before a male staffer with a face as dark and thin as a burdock root led me to a small private room.

“Hello-aru! Welcome-ne!”

The girl who entered was a brunette in a cheongsam, her hair tied up in twin buns. She was a full head shorter than me and spoke with a bizarre sentence ending I couldn’t quite place.

Vanilla hadn’t lied; the girl was cute, with big, round eyes. And she was, as promised, exceptionally well-endowed.

“You the one Vanilla-chan recommended-ne! Nice to meet you-aru!”

“Nice to meet you, too.” My tongue tripped over the words.

“No need for formalities-yo. Is this your first time at a shop like this-aru?”

“Actually, yes.”

“Hehe. You’re cute-aru. I’m Rinsu. Nice to meet you-ne.”

“Rinsu.”

“People get a kick out of it when Chinese girls say ‘aru,’ you know?”

“I see.”

“Rinsu-chan is a devoted woman who meets her customers’ demands-aru! Now, now. Hurry up and take off your clothes. I will provide service-aru.”

Before I could even process her words, Rinsu was already undressing me and turning on the hot water in the attached shower.

“Ya-pa-pa, ya-pa-pa, ii-shan-ten…”

Humming a playful tune, Rinsu began to wash my body with meticulous care. Her small hands, slick with soap, glided over my skin. She gave a satisfied little hum.

“I heard from Vanilla-chan-aru. Saki, you have bottomless stamina, right-aru?”

“Hey now. Her information is seriously distorted.”

“No need to be shy-aru. It is proof of vitality. Are you looking to be made ‘empty’-aru?”

“Empty?”

“Aru.”

She flashed a professional smile. “I am a pro, after all. So, what will it be-aru?”

“…Empty, then. Until there’s nothing left.”

“Understood-aru!”

After rinsing the soap away with the shower head, Rinsu rolled me onto a flat massage bed. Straddling me, she began to touch my body with a gentle, practiced hand.

A sharp jolt of stimulation raced through me.

“Does it hurt-aru?”

“A little.”

“You will get used to it soon-aru.”

Then, she nipped at me with her teeth.

A low groan escaped my throat before I could stop it.

“A sensation you do not usually feel, yes-aru?”

It was a slow, creeping feeling that seemed to well up from deep within my core.

Pleasure for the sake of pleasure. It was the first time I’d ever been “attacked” by someone who understood exactly where to strike to elicit a response.

Compared to this, the sex with Mii felt almost bestial.

If I had to put it into words, that was sex for the sake of sex. The pleasure was just a byproduct. Even if there was no ecstasy to be found, we would probably still press our bodies together. Sometimes, I truly lost sight of why we were even doing it.

I opened my eyes to find Rinsu’s face inches from mine. Her eyelashes were as elaborately decorated as the dragon on the sign outside. Her brown eyes watched me with an almost clinical curiosity.

“Were you imagining another woman just now-aru?”

“Is it really that obvious?”

“I can tell-aru.”

She gave a huff of breath and stroked my stomach.

“You should think about the girl right in front of you-aru. That is just manners when making love, isn’t it-ne?”

“You’re absolutely right.”

I’d been told the exact same thing only a short while ago.

“Then, let us begin-aru.”

Sliding her hand against my cheek, she pressed her lips to mine. Her tongue slipped into my mouth, invading every corner like a serpent, from the top of my mouth to the back of my teeth.

“I will take care of you with my mouth-aru.”

It was lukewarm. Pleasure for the sake of pleasure.

Sixty minutes. Twelve thousand yen. Three rounds.

I couldn’t believe it myself, especially after everything I’d done the day before.

“Now you are completely empty-aru,” Rinsu said with a look of immense satisfaction after rinsing her mouth.
