yeah was about to say, if you want to save your sister from a whore house, why not just buy her?

I get the feeling that the Witch works with the Whore House to pull this kind of stunt often.

I'm okay with the MC breaking, but the dude didn't save his sister in the end. Why you gotta have that last page just to show a bullshit ending, why not have the sister escape and pledge to find her brother? Still sad cause she doesn't know, but also teases a follow up.

What could go wrong?

EVERYTHING!

So why is she have to sell her body in the first place? her brother is a fucking knight, his income cannot satisfy her spending?

When you're born as a character in a hentai manga or anime, you have to check your brain in at the birth canal before passing through.

Base +6, OtleChip +6

I don't expect much from a hentai plotwise but it's a bit annoying when the artist doesn't even try.

Base +6, jere512 +6, OtleChip +6

Apparently, the TS brother didn't even bother visiting his sister to find out any details before taking the sex change potion.
