This special work focuses intensely on Yuzuno-chan's armpits and the surrounding areas. It begins with gentle tickling under her right armpit using a brush, carefully stimulating the area with both the tip and the handle, gliding and poking to elicit reactions. Each time, Yuzuno lets out adorable sounds like "Ah, aha, ugh, nooo, ehehe," twisting her body in delight—her reactions are incredibly vivid. The attention then shifts to her left armpit, where the brush continues its teasing tickles, drawing out irresistibly cute responses. After setting the brush aside, both hands are used to tickle under each armpit, causing Yuzuno to giggle, squeeze and spread her legs, and shift her sitting position in reaction. Next, the blindfold is removed, and lotion-covered gloves are applied for a new round of tickling. With the slippery gloves, her writhing becomes more intense, her laughter louder, and her nipples visibly erect, peeking through her movements. The focus returns to her right armpit, where her right hand is pinned down and pulled from her head, allowing continuous tickling underneath. Her laughter grows even more frequent and joyful when her hand is lowered, and the face-to-face scene where both armpits are tickled is especially memorable. Her cries of "Ihi, aha!" clearly reveal just how sensitive her armpits are. This work fully showcases Yuzuno's charm through the detailed tickling techniques and her expressive reactions. A highly recommended title—don't miss it!
