Akane Nanao - From "Akane wa Tsumare Somerareru/Akane's In A Pinch" by Takeda Hiromitsu - Holy Code '247599'
Nagiko Uwabami - From "Dosukebe Chinpo Dorei ~Yokai Nekomata Sono 2~" & "Mesubuta (Dosukebe) Chinpo Dorei ~Taiiku Kyoushi Uwabami Nariko*~" - Holy Codes '450836' & '454873'. First one has questionable grammar and the latter isn't in English yet.
*There's either a mistranslation in the title for the hentai or in the hentai itself, because one says she's called Nagiko and the other says Nariko. I'm too lazy to change it to Nariko throughout both the chapters she's in as well, so henceforth she'll be referred to as Nagiko. Sue me, I don't get paid for this.
