My Sister’s Discipline Log

Steam Video Games Windows


My kind, beautiful little sister has a hemorrhoid?!
It all begins when the protagonist’s little sister opens up to him about her awkward dilemma, leading him to buy a suppository for her. However…

"Onii-chan… I can’t… get it all the way inside…"

She fails to put the suppository inside on her own.
Surprisingly enough, suppositories are pretty difficult to insert without someone else’s help.

"O-Onii-chan… can you please… put it in for me…?"

Huh?! Y-You don’t care if your brother sees your butt?!

She gathers up her courage to make that embarrassing request, shaking all the while with her face beet red.
Her brother’s sense of reason nearly shatters when he sees his adorable sister in that helpless state!
How will he respond?!

Well… things rapidly escalate, reaching a point where even his little sister’s best friend gets caught up in the ensuing craziness…


Miu – The Protagonist’s Little Sister
Voice Actress: Noa Namiki

I’m probably not the right person to be saying this as her older brother, but my little sister is gorgeous.
And I’m not some little sister fanatic, either. She really is a beauty without so much as a single flaw.
She has long, straight hair that extends past her shoulders. It’s silky smooth, too; you’d almost think she just got out of the bath. She also has bangs like your stereotypical rich girl does.
Obviously her face is quite the spectacle, as well. She has large, round eyes and a very straight nose bridge. Honestly, it’d be a pain to explain her perfection in detail.
The general impression you’d get upon seeing her is that of innocence. I guess the most striking things about her are her peachy-smooth cheeks and plump limps. It honestly makes my blood boil thinking about how some random guy will eventually take her first kiss. I’m sure our dad feels the same way.

Kana – His Little Sister’s Best Friend
Voice Actress: Kei Yasutani

Miu’s best friend who lives in our neighborhood.
She often comes over to our house and spends the night.
She’s a beauty on par with Miu.
Compared to Miu’s gentle demeanor, she has a more calm and collected air about her that brings to mind that of an intellectual.
She’s about the same height as Miu, though. They almost look like a pair of idols when lined up walking together.
