Seria finds herself securely bound to a chair, her hands and feet completely restrained, unable to escape the overwhelming ticklish sensations that await her. Behind her, Mistress Mei steps forward with a playful smirk, holding an array of teasing tools. With every delicate stroke of a feather, Seria erupts into uncontrollable laughter, her sensitivity exposed. Mei explores every inch of her vulnerable body, gliding across her belly, neck, legs, inner thighs, chest, and back, drawing out waves of giggles and gasps. The sensations intensify as Mei introduces a taisho-fude (large calligraphy brush), tracing kanji characters over Seria’s soft skin. Each careful stroke sends tingling sensations through her body, blurring the line between pleasure and sweet agony. Mei’s collection of tools continues to expand—pinwheel rollers dance across Seria’s skin, creating delightful shivers, while metal claws graze her calves and knees, leaving her squirming in breathless laughter. As Seria's giggles turn into desperate gasps, saliva trickles from her gagged mouth, a testament to her total surrender to the ticklish sensations. Mei isn't finished yet—she picks up plastic forks, dragging them across Seria’s sensitive skin before introducing an electric toothbrush between her toes, sending her into uncontrollable squeals and moans of exhaustion. Finally, Mei completes her masterpiece with a small, ultra-fine brush, teasing the delicate hollows of Seria’s armpits until she reaches her limits. By the end, Seria is left breathless and giggling, completely enveloped in the relentless symphony of sensation.
