Good start, but the end was just.. eh. Another one of "those". It looked like it could have been something more.

Trololo...

Nevermind, lmao.

Are they really sisters? If so, the incest tag should be up there too... I know that sometimes in Japan younger girls will call older girls that are not family big sisters, so is that the case here? I'm confused...

It's the latter case, yep. They're not related.

has an older sister, but they're not actual sisters? reminds me of kuzu no honkai... except it's with an "older brother" lol
