Holy shit. That was... Something...
Welp. That aside, I kinda wanna read a wholesome version of this now, where sis and bro reconcile and like take care of each other after being abandoned by their parents like that. Preferably without rape of course.
I do like how the author of this portrayed rape as the dark act that it is, rather than most manga which downplays it by making it seem like the victim likes it or whatever.
Cant really get off to this though, thankfully.
