[Mycology. (Ainaryumu)] Kawaii ni Yowai Inkya Danshi ga Mesu Ochi suru made Zenpen [mysterymeat3]

Haru only meant to snoop through one suspicious box while waiting for tea at his classmate Shuuji's place—instead the shy boy ends up squeezed into a borrowed schoolgirl uniform, squirming as Shuuji showers him with breathless praise. Embarrassment burns off fast into something hungrier, and soon Haru's hesitant hand is wrapped around Shuuji's aching cock while his own strains hot and neglected against thin fabric. The first half of a slow-burn feminization romance that leaves its blushing hero—and readers—aching for part two.
