I thought megumi sister is adopted
They aren't blood related
Right, they aren’t blood related but they are raised like sibling and, in the canon, they have a sibling relationship.
For me, it’s incest, even if they aren’t blood related because the taboo is the same. You’re not supose to love or want to sleep with the people who are a family figure with you.
Yes, but the term incest applies only in the case of sexual practices between consanguinees.
By the way I understand what you explain, I don't consider it correct either
Soooo… that’s funny. Megumi’s simp rage on doujin with bottom Megumi and the only top Megumi on mangago have incest.
If it’s make on purpose, that’s perfect xD
