The latest installment in the private training series by Tuning Club staff! "Kana," who couldn't forget the pleasure she experienced during her training seven years ago, has returned to request another session. Haunted by that memory, she's been tormented with longing ever since. Her desire to be tied up, to blossom further as a true female masochist, grows stronger each day. "Please," she pleads to the staff, "won't you tie me up?" But the staff won't comply so easily. They demand she expose her true perverted nature—show them something more depraved if she truly wants to be bound. And so, obediently following their orders, Kana gradually reveals her most shameful acts, surrendering completely to fulfill her deepest desires.
