Drawn by the collaboration between Kousaka Himari and Houshou Mei, I picked up this work. The lesbian doctor health checkup themed around nipple development, with its shame-inducing direction, is irresistible. Kousaka Himari's nipple orgasms are spectacular, and Houshou Mei's mysterious climax is incredibly erotic. Scenes like grabbing large breasts like an eagle, pressing them against glass, and breast suction leading to fully erect nipples captivate the viewer. The progression from cunnilingus and shell matching while kneading nipples to nipple-induced squirting orgasms is natural and arousing. The breasts are beautiful and full of highlights, and I'd love to see occupation-specific nipple kneading clinics for OLs, nurses, and maid cafes. A revenge plot where students turn the tables on the teacher would also be interesting, building anticipation for future series. Overall, it thoroughly explores nipple sensitivity and is a must-watch for fans.
