A sister in heat. How touching :D

Sweeeeeet ! :3
Imagine this : a tsundere, excessively cute and eroge-fanatic aroused sister barges into her brother’s room, threatens him of false sexual harassment accusations (did he need to be convinced, frankly ?), and she jumps at his penis.
Isn’t the hentai world wonderful, honestly ? :lol:

It’s a lot of fun, it’s well drawn and sexually it gradually becomes very intense, it was great ! :D Thank you VERY much to Gurumao and Nashrakh ! :)

A remark, there’s a “volume 1” on the cover, but no scans of any other volume are available so far. Maybe the artist is planning to release more volumes in the future comikets ?

Update : this is a My Little Sister Can’t Be This Cute doujin.

By the same artist, going under the pen names of Raijinkai (I’ve sometimes seen Rajinkai) and Haruki Genia (or Harukigenia), I also share a pack of 4 works (Migurui volumes 1 and 2 + Mio-chan No Binetsu Kaishou Daisakusen + Wolf Road), Love Manaka and Sena’s Erotic Display.

Thank you very much for the gold key, Oliver! And now, time to get you another one with a ridiculous amount of downloads! ;)


i think its based off this manga if u want some background info on the characters


Cheers Oliver. I already have a Gold account, mainly because I download a lot of stuff from you. But the sentiment is appreciated.


Thanks Oliver, Gurumao and Nashrakh. Nice little manga; fun to read and nice to look at.


been reading this manga and looking forward to the anime later this yr so I enjoyed this one


Thanks for the Upload Oliver, btw if you liked this doujin you should try reading "my little sister can´t be this cute"

here a link :


I think someone should speak up and mention that this is a doujin


I absolutely *love* that "I AM IN HEAT!" picture. The whole story is really, really good too. The cute tsundere sister who won't take no for an answer, the rather intense bondage and vibrator scene, and the hilarious last page just add up to a total win in by book. Many thanks to Gurumao and Nashrakh for their work on this, and thanks Oliver for sharing. I am *so* hoping that there will be more like these to come.


Great, just great.


I think there'll be a sequel. There's an illustration of another girl, a character from the original source material maybe? She might get involved or have her own separate story in the next volume.

Regardless, I enjoyed this one. It was fun and the incest didn't really bother me too much, the ending was also really funny.


i cant wait for the anime of this light novel / manga ^^


same, cause that means more doujins of this series. looking forward to what C78 brings.


it was actually more fun reading what happened rather than the actual sex. I was laughing so damn hard reading it. Reminds me of that other one that Oliver posted about the siscon brother who moved away, but his sister finally ended up living with him (it's non pornographic though)


You're referring to the ecchi manga "Oniichan Control". The yandere is completely insane and lovable at the same time. It's on Oliver's blog as well.


here is the chapter 8 of the manga but its in spanish (the link that oliver shared only have up to chapter7):


hey Oliver, I just wanted to let you know that the author is Harukigenia, and Raijinkai is the circle he belongs to. Just a little update :D


Thank you I have been waiting for the next one of this, its comedy’s definition. And very good.


The djn is cool .. but the "original" manga is such a pain in the ass…. Seriously…. is that "dude" a man or a motherfucking sack of potatoes….-__- … She treats him like garbage and he doesnt do shit…
Sometimes I wonder what the fuck is wrong with some mangakas…

Doing shit would involve effort – too much like work!
(Some girls have the same attitude – they're called: 'Whores'!)


Page 19, yeah this is worth a look, thanks for the upload.

This work reflects the spirit of my own so eerily, it is disturbing!
I thought Hentai was all: 'Guy Gets Horny + Girl Bends Over = Act of Rape Ensues'!
Thank You, Oliver for changing my set-in-cement opinion! <3
This work is great, look forward to finding more! :)
