Kimagure Oneechan (“Capricious Big Sister”) [English], by Toushiki Yubune
I was randomly browsing my “mostly recent” downloads two days ago, and remembered there was this modest gem I had wanted to share, so let’s not delay any further! ^^
Kimagure Oneechan, with its simple straightforward setup, had pleasantly old-school vibes, with a drawing style (you know, all these idiosyncrasies making each mangaka mostly unique) that felt quite pleasant and uncommon
In terms of story, it’s a highschool sister noticing her brother is now troubled by the sight of her legs, and so, logically (Hentai World Logic ©®™), she teases him so much they end up banging. As for the rest, well, see for yourselves, it’s uncensored, it’s enjoyable, deal with it at your own pervy convenience!
The scanlation and decensoring were made by Bunzero and Bunluna, from Occult Buns, thank you very much! ^_^

i must say, that was pretty cute, if you can blank out the fact that they could potentially have to explain to their parents why a bunch of recuring genes is coming in 9 months…
Thanks for the share!
Is there even a doubt, that their parents are also brother and sister, as are their grandparents, and so on?
“Big sisters have the responsibility to check and see if their beloved younger brothers are growing into true men.” – Nee-chan’s quote from Page 4.
One may wonder whether one day, such a statement will come forth regarding THIS pair of siblings:

That look on her face as they were about to do it raw and she was screaming: “I’m a virgin! Be gentle or I’m going to f*cking kill you!!!” was PRICELESS.
I was laughing the whole time I replayed that scene in my mind. lol
You are about to enter another dimension. A dimension not only of sight and sound but of mind. A journey into a wondrous land of imagination. Next stop—The Hentai Zone.
One has to wonder the type of hentai stories that Rod Serling and the Twilight Zone script writers would’ve come up with.
Pages 19 & 20? That’s an ass begging to be fucked. Because, you know, big sisters have a duty, yada, yada, yada…
Other than the eyes being on the weird side, a fun little brainless story.
And has been mentioned, p. 14 is comedy gold, LOL. “Since I’m an adult, move as much as you want.” Next frame: “Ow ow ow ow ow! I’m a virgin all right? Be a little considerate or I’m gonna f*cking kill you!” ROFLMAO!!
They both have the same haircut, but she pulls off the look better.
