[草野郎] 少年陰陽師の悪堕ち淫魔化漫画、淫魔姉妹誕生編12P（TSF＆洗脳＆催眠）

Ngl I wouldn't mind 60 pages

I'm just really impressed how this author packed in so much story in 12 pages and there weren't even that many panels in the pages! Like this is just a good comic book writing first and porn second. They managed to describe without so much expositions: 1) their relationships and missions; 2) the older sibling's motive; 3) how the demon power is / how the older sibling got turned; 4) the boss demoness(Martha) that never even showed up; and 5) the stage where the whole event took place. If this was a bad writer it could have been a 60 page saga.
