[Amuai Okashi Seisakusho (Betty)] Mass-Gender Bended Gyarus, Fall into Depravity [Blavatsky Project]

A classroom of former boys wakes up transformed into busty gyaru schoolgirls, and instead of fighting their new bodies they decide a life spent teasing, moaning, and spreading their legs beats studying any day. As one studious classmate feels her once-sharp mind fog over with every easy question she can no longer answer, the rest of the group sinks deeper into depravity, until an organized sex party with classmates becomes just the usual after-school routine. What begins as a drugged mass gender change ends with masochistic gyarus eagerly trading their old identities for a long relationship with cock.
