RCW 9A.64.020 (1)(a) A person is guilty of incest in the first degree if he or she engages in sexual intercourse with a person whom he or she knows to be related to him or her, either legitimately or illegitimately, as an ancestor, descendant, brother, or sister of either the whole or the half blood.
That’s the REAL definition of incest not the one you made up in your head. read what you want it’s fiction who cares but incest is a REAL LIFE PROBLEM. you are invalidating abuse from real people when you spew BS like this. adopted siblings can’t even get married bc the courts know ITS INCEST. read what you want, but you do not have to defend incest so you won’t feel bad about it.
Sure they both lived as "brothers" but guys.. the exact definition of incest is relationships between BIOLOGICAL members of a family. This isn't incest lol. And if its still gross to you, just try to think of it as they lived as good friends for a long while idk
