For those of you not familiar with this story, this is actually a remake or retelling of Scarlet Desire. This story was published in Action Pizazz and apparently the publisher didn't like the idea of mother=son incest so Nishimaki Tohru changed it (sold out) to stepmother-son. Dear My Mother was published in 2 volumes, the first volume (1-8 + bonus) was translated by Tadanohito https://e-hentai.org/g/519391/225be1a944/. I was able to find most of the remaining chapters in individual volumes of Action Pizazz but I couldn't find chapters 9-11 which would've been in volumes prior to 2013-3 which aren't posted on this site. If anyone has access to the previous volumes of Action Pizazz, or even the published tankoubon of Dear My Mother volume 2 (not to be confused with Dear My Mother 2 volume 1 which is a continuation!) I will add it as well.
