😈 Sakusei Kenkyujo (The Seed Extraction Lab) / Umeda
The Next Generation of “M-Seikan” has arrived like a comet, now reigning at the peak of the industry.
In an era where the “M-Seikan” (Masochistic Sensual Massage) scene is aging, we bring you a hybrid professional lineup of “Chijo” (Nympho/Succubus) therapists. They combine youthful energy with top-tier technical quality.
We also feature a roster of highly skilled veterans with refined techniques.
- Will you enjoy the next-gen therapists who have evolved rapidly by learning from the masters?
- Or will you be dominated by our hybrid succubi, where youthful innovation meets legendary ancient techniques?
The choice is yours.

💡 Tips for English Speakers
- M-Seikan: This refers to a “Masochistic” massage experience where the female therapist takes a dominant role.
- Succubus/Chijo Experience: The term “Sakusei” literally means “Seed Extraction,” implying a highly intense, draining, and pleasurable experience.

Manager’s Comment
— Fall under the spell of her fingertips.
A soft breath you can feel through the blindfold.
With your vision taken away, the first thing that touches you is—
Kanano’s slender, delicate fingers.
Innocent pink hair.
A small-animal-like, pure cuteness.
But if you let your guard down because of her looks… you’re done.
Her true weapon is her slow, relentless nipple teasing.
She never misses a single reaction,
skillfully pulling you deeper into a swamp of pleasure.
With her slender, lovely figure,
being teased while blindfolded
promises excitement beyond imagination.
And then… at just the right moment,
when the blindfold is gently removed—
What stands before you
is no longer just a cute girl.
Please, by Kanano’s hands,
experience what it truly means
to be “controlled by pleasure.”

“It Was Very Good”
[About the Girl]
She looked exactly like her photos.
When I actually met her, she was just as cute as in the pictures, which reassured me.
She gave a slightly shy impression at first, but she was actually a cheerful girl who talked to me easily.
[Price Satisfaction]
It felt a bit expensive, but considering the content of the service, it was totally worth it.
[Play Details]
She blindfolded me, and then started with teasing touches from my feet, finishing me off by hand.
Personally, I really liked the way she whispered in my ear.
I’d definitely like to use her services again.
[Staff Response]
They responded kindly, so I was able to use the service with peace of mind.
I also liked how they spoke to me in a friendly manner.
