Maybe it's the translation, but this looked so hot at first and turned out to be something incredibly ass backwards. For starters, why is the "mom" calling her daughter Megumi-san? As if she's the younger one. Then when the mom is saying, "Please keep it a secret" the daughter finishes her sentence by saying, "MY husband." So like, WHO are they talking about? Is the daughter supposed to be married? Doesn't help how she says "Otou-sama" on the next page, a word we hardly ever see instead of dad. The dialog invokes a lot of unnecessary mindfuckery when it's bad enough how the daughter couldn't be a loli.
@Marien They are not blood related, Megumi used to be the girlfriend of the son, but he was a faggot. Megumi then fucks the dad and now they live in the same house. The tags are wrong, there is no incest here
