Part 1: 5-star ratings and glowing reviews.
Getting a reservation at this hidden massage parlor is practically impossible. Somehow, Koharu managed to bag a slot. This would be her first massage in a long time, and her chest fluttered as she rang the intercom...
From within, two handsome young men appeared and ushered her inside. Though a little confused, Koharu begins her counseling...
"In terms of today's treatment, is there any kind of play you'd rather we not do?"
She was surprised enough at the word "play" but the words that followed were all far too explicit. Cunnilingus? Vibrator?
That's right. This was no ordinary massage parlor. This was an erotic massage parlor...

Part 2: That popular 5 star massage-parlor is fully booked with reservations for the next 6 months.
In order to improve the situation, Naoya and Hiroto decide to hire more staff... and request of the frequent customer Koharu to oversee their induction course----
Before the watchful gaze of Naoya and Hiroto, Koharu is teased and toyed with by the two newcomers...
Or at least---- that is what was supposed to happen, but something's not quite right...?
