Features a pair of heroines named Pale Agate and Morganite Bunny. Each chapter branches to a Bad End (first) and Good End (later).
I will update this gallery as new chapters are released, though in this case I had to create a new gallery since the board does not allow unlocking and updating of galleries older than 1 year.
悪堕ち系変身ヒロイン!モルガナイトバニー・ダークインレ : pg. 1-6 うさみみ系変身ヒロインに甘やかされて / だくな式乳性交指南 : pg. 7-39 Pale Agate 11 : p. 40-239
Note: even though the Morganite Bunny side chapters are newer, the author puts the before Chapter 11 (with regards to chapter ordering), so I'm following suit and putting them first.
