From flat chested girlfriend to busty gal

A school-uniformed girlfriend with newly enormous breasts becomes the center of a rough-translation comedy about obsession, teasing, and a boyfriend increasingly unable to keep his composure. Her confident, playful approach turns increasingly physical across the pages, while the banter repeatedly circles around gentleness, cheating, and whether he can handle her transformed figure. The closing spread widens the playful conspiracy by bringing Asuka and Sumida into a discussion of work, timing, and continuing the encounter, ending on a mischievous promise of more.
