Okay, so I'm generally not in the habit of translating other people's English. With all due respect to the author, I thought I would render my own English translation. Despite the fact that the author translated it himself (herself?), it was clear that it was a pretty straightforward machine translation used by someone who's primary language is not English. I'm not criticizing! I'm glad the author made the effort! Anyone here can feel free to choose whichever version they like!

As none of the others posted the Japanese version, I won't either. It took some effort to get the original Japanese version from DLSite, but I'm glad I did! I'd rather translate from the original source, after all.

I decided to go all out on this, decensoring and clearing out the SFX text. I usually don't do that but, like Kana, once I got started I couldn't stop! I will make a textless version available at a later date for anyone else who wants to use it.

Hope you enjoy!

UPDATE:
If I had my way, this would be the sequel rather than the abusive one that was made:

Natsumi and Tsubaki send a note to Kana at school saying to meet them at Tsubaki's house. Her parents aren't home and neither are Kaeda or Hikari there, the two older girls want to have some more fun with Kana.

Kana is cooperative but would like to set a few ground rules.
"Your grades are okay but not yet good enough to get into college," she says. "I can help you with that, and in exchange I will let you have your way with me." Kana gets an erection even suggesting this.
"But if your grades go up too much too fast, it will be suspicious. They will have to go up gradually, as if you were applying yourself more in the class. What I can do is provide you with some of answers to the tests, since as class leader, I have access. Then, we can set on a time and a place for a "study group" where we can get together and play in private. You can do whatever you want to me. But please leave your little sisters out of it, I may have enjoyed them playing with me but I'm uncomfortable having such young girls doing that to me. You can do anything you like, but please don't leave any visible marks on my body. Otherwise I'll do what you say."

Natsumi and Tsubaki get together and talk it over.

"We'll agree to this if you agree to masturbate on camera and say how much you enjoy exhibitionism and masochism, and you agree to be our sex slave. This way it will be clear that what we do is consensual and not forced.
We also want to push the boundaries, finding secluded places where we can play with you where you might get caught in a compromising position, or bring one or two more girls in on it also, just to increase the embarrassment. They would agree to be bound by the same rules.
You also have to be honest with us and tell us anything we want to know: what you like, when you started, every intimate and personal detail about your sex needs.
This will go on until we graduate from high school, then we'll delete the images and video. But if you try to harm us in any way before then, we'll release them and ruin your life."

Kana agrees, though she can't help them with college entrance exams except to help them study.

"It's better for me," she says, "Less dangerous than masturbating in public. It would give me the release I need. And if you want me to be honest, I admit I'm getting excited just thinking about what you will do to me. I don't even mind other people joining in, as long as they keep my secret."

They all agree and get started on a session, the first of many, dealing with different aspects of BDSM.

@doll kara, @dafdagh...To be honest, while I'm a fan of this kind of embarrassment and of blackmail scenarios, I'm not really a fan of physical abuse, sorry

there is no sequel with the older sisters?

Base +6, Soul172 +6, CreeperClaw +10, hbm +6, Neotruth +6

@MisterJ167 Do you have the sequel where the little girls do kickball busting? I can't access X Hentai, so I can't view it on E-Hentai.

Base +1, kageganon -6, anomahous -13, covs -6

i searched it up and the sequel is indeed out, but it doesnt make much sense as there is no progression, older sisters are basically still not involved and im not into the stepping kink either
