My first manga translation in 3 years. Not sure if I still got it, but after countless revisions I think we've got something at least decent.
Partially decensored like most of my other TLs.
Enjoy!

Damn she noticed how he feels about her. Wonderful younger sister.

That was pretty deep...
Being an angelic sister both physically and in personality-wise.. Made the older brother feel even worse...
Tetsuyama Kaya makes some of the best stories...
Thanks for sharing

Not going to lie, I was expecting a panel involving suicide with how that last page was going.

I love the protagonists that realize what they are doing is wrong, thus its more interesting when their twisted love is seen at first to be reciprocated by their affection. However when they begin to question that and achieve it, there's still that void of dread. Thanks for the translation frogstat

Dude has serious self esteem issues. He says he hates her, but he actually hates himself.
His sister is a blessing for him. She's trying to accept all of him to make him not feel bad about himself. Heck, she even asked for more after he choked her...

Also rejoice because this has a sequel in c97: https://www.pixiv.net/en/artworks/78361533
We just have to wait for someone to pick it...

@ Juggernaut Santa:
that c97 story is not sequel of this story, character have different name, it is just another story of brother and sister fucking.
Most likely the author is creating a series of story of sibling fucking each other which each story sibling is from different family to put in a tank with theme ( the title) of bother and sister fucking each other brain out.
