[Kasetsu Makoto] The Litmus of Adolescence (COMIC HOTMILK 2022-02) [Nisor]

Saku, a tall schoolgirl whose uniform barely contains her big ass and heavy chest, decides her studious junior Ei-kun has earned a hands-on reward now that he's topped the class—starting with a breezy, pantyless surprise bent over a desk in classroom 2-A. What begins as their private self-study session spirals into groping, kissing, and a breathless first time that leaves the schoolgirl in full ahegao, demanding they finish at his place. By the last page, two pairs of shoes sit side by side with little hearts floating between them, promising the reward system is far from over.
