Steal

Well, they may have seemed happy, but if she's so impulsive that she can so easily swap to another guy with just a little push?
Then maybe she and our protagonist just weren't meant to be. Besides, next thing you know she dumps the tutor for someone else.
That being said, was her sister justified in breaking them up because she genuinely came to fall in love with him and was probably jealous?
Probably not, but it probably really doesn't matter as long as they're all sort of happy in the end. It got wrapped up quite nicely, and what he doesn't know won't hurt him, I guess. To him, she's pretty much his Angel of solace who saved him in a time of grief and...Well, poor guy has probably suffered enough.

It's odd! It's not ntr but she caused the break-up between her sister and her ex-boyfriend.
So... "plotting" tag? ¯\(â—‰†¿â—‰)/¯

Well... at least he's ending up with the smarter girl. ^_^;

Steal? i think it's more like blessing to me '3'

i like the imouto more anyway so im fine with this

Twintails, stockings and panties my these tropes never go out of style.

Will Matsunaga-san one day find out "the truth" regarding the break-up with the elder sister and subsequent hook-up with the younger one?

THERE CAN BE ONLY ONE way to find out ... assumng he can handle the truth.

Good read but I don't think it needs the irrumatio tag.

I am conflicted as hell atm. This is kinda fucked up right? Right?

Damn thats a girl that knows what she wants. A great release and I can't wait to see what Yuta has for us next time.

I don't know exactly how to feel about her and stealing away her sisters boyfriend. A sequel could help clear everything up... And while we are at it: Okumoto Yuta needs to release a book...

Not Satisfied with this Cliffhanger!
