■Experience report

This time I suddenly wanted to go to Yoshiwara after a long while, so I entered as a no-selection (free) customer.
I couldn't remember Yuzuki's rules very well, and they carefully asked whether it was my first time. Was free only allowed from the second visit onward?
First-timers should confirm this in advance.


Around 2 PM as a free customer, Rinriko, Kokoro, and Keiko were on the board, but I couldn't resist the instinct to bury my face in a bust, so I requested Kokoro.


As usual I drank a Yunker and waited; I was guided and greeted in the elevator.


My first impression was a strikingly pretty face, but my eyes were drawn even more to her large breasts that were pushed together and lifted.


After entering the room she gave the traditional three-fingered greeting again, and I was reminded why Yuzuki is special.


We chatted about trivial things while she carefully helped me undress. When I nervously asked "Can you undress me too?" in the usual routine, she undressed me.
Not only was her bust ample, but her slim waist and slightly large buttocks were revealed, and I was in an excited state.

Experience Report ①


[From booking to meeting]
I suddenly had time, so I decided to go to a famous shop I had never visited before.
Looking at Yuzuki's page, Kokoro, a petite busty girl I like, seemed available, so I booked by phone.
I arrived at the shop and paid the bathing fee at reception.
The girl's fee is paid separately.
That's rare these days.
While waiting in the lounge there were about three other people even though it was an early weekday hour.
The place seems pretty popular.
At high-end shops it's common to only see a few customers at this hour.
While waiting they served tea, a snack, and a Yunker.
After a while my name was called, and I met her in the elevator.
First impression: full eyes, a small, well-defined nose.
The mouth and jawline were slightly concerning, but overall cute.
Her figure is exactly petite, slender, and busty—wonderful. Expectations rose.
We walked arm-in-arm to the room.
[First round]
We entered the room, chatted, and she gave full-assist undressing.
She even gave a deep kiss during the process.
After she finished undressing me she said, "Let me undress you too," so she removed my dress and bra.
Her breasts that came out of the bra were quite large and well-shaped.
The areolas and nipples are slightly large, to my taste.
Then she began to lick my nipples.
I gradually responded, and the visual impact of her breasts contributed to me getting hard.
From there she moved to my penis and performed oral sex.
The oral felt quite good.
Then she said "Stand," so I did a standing fellatio.
That was pretty nice.
However, around this point one concern arose.

Experience Report ②

Yoshiwara luxury soap.
For someone like me whose main field is high-end delivery health, Yoshiwara has been an unexpectedly distant world.
My last Yoshiwara visit was before the system changed at Shogun, if that rings a bell.
After wondering where to go, I chose Yuzuki, a long-established shop in Yoshiwara.
I believed there must be a reason it lasted so long.
At about 3 PM, after being certain my work finished at 5 PM, I called the shop.
The girl I first hoped for wasn't available, so after talking with staff I settled on Kokoro, a natural G-cup.
By the time I finished work and arrived at the pickup point Minami-Senju Station, it was already deep night.
A black Alphard waited in the darkness of the night.
When I called, that Alphard was my ride.
I was the only passenger, and I arrived at Yuzuki in a private transfer.
At the entrance the reception desk is on the left; I first paid ¥27,500 (or maybe ¥30,000), and then the remaining amount is paid directly to the girl later.
You're checked with a metal detector in a lounge with four sofa seats. I chose coffee from the drink menu, and they served snacks and a Yunker royal liquid.
I waited in the room for about 10 minutes.
My name was called and I met Kokoro in the elevator.
Her G-cup breasts visible through a negligee-like dress; visually her facial features are sharp and clear.
The site described her as announcer-type, but I didn't find her particularly announcer-like.
After greetings in the elevator we walked arm-in-arm to the room with her pressing her breasts against me.
After greeting again in the room, she assisted with undressing while we chatted.
When we were down to a single towel Kokoro said
"Undress me."
She lowered the dress zipper.
No bra, Kokoro's naked figure was of course G-cup with a slim waist—quite something.
*I stopped trying to hurry and took the time to appreciate it properly.
