[Amuai Okashi Seisakusho (Betty)] Group Gyarufication and Degeneration {Sankaku Scans}

A whole classroom of students wakes up transformed into busty, airheaded gyarus — including one newly minted girl who can barely solve simple problems anymore, let alone resist the overwhelming sensitivity of her new body. What begins as teasing the former class clown about 'ruining your fun life as a girl' spirals into breathless first-time discovery and a teacher-declared pleasure party that turns the entire room into a shameless group free-for-all. As Fuyuki, Akino, and Natsuo each unravel under their instructors' attention, the degeneration runs from flustered virginal gasps to full masochist bliss with no one walking out unchanged.
