Ero Manga Onee-chan!! ~Damedame na Ane to no Amaama Cosplay Ecchi na Hibi~

The protagonist has been living with his step-sister, who is much older than him, since his parents left home for a long-term overseas assignment.

The sister lives alone because she wants to focus on her work, but she supports the protagonist and sends him to school.

But one day… “Eh? The payments have stopped??”

The protagonist is suddenly kicked out of the school dormitory for non-payment.

He is forced to go to the apartment where his sister lives alone–

“She’s dead!!”

He finds his sister collapsed in her underwear.

But she’s not dead.

“It’s no good, it’s all over now…”

“Sister…?”

The sister is actually a manga artist, and she’s in a serious slump.

Because of this, her work has been delayed, and the rent for the dormitory has stopped being paid.

“Ugh, little brother… I can’t think of anything…”

“Sister… You’ve pushed yourself so hard for me…”

The protagonist makes a decision.

Now is the time to support his sister who has been working so hard.
He blurted out the words with that thought.
“Don’t worry! I’ll help you with anything, even coming up with ideas!”
“Really…? Did you just say “anything…?”
That statement would greatly change the fate of the brother and sister.
Because his sister is not just a manga artist.
“I’ve kept it a secret up until now… but… I was supporting my dad by drawing erotic manga…”
And so, to save his good-for-nothing, perverted sister.
And to create even better erotic manga.
Their innocent yet greedy sex life begins…!!
