Beautiful office lady An-chan visits the clinic to relieve muscle tension. As the session begins, an unusual atmosphere fills the room, different from the usual relaxing vibe. While enjoying the massage, she gradually feels a strange ticklish sensation. Following the therapist's instructions, her clothes are slowly removed and her limbs restrained one by one. With each restraint, the ticklish sensation intensifies, causing her to burst out laughing: "Gyahahah!! N-no more!! Yahaha, it's too ticklish!!" But the so-called treatment continues relentlessly. Trapped in an inescapable hell of laughter, she deeply regrets ever coming to this clinic.
