You’re mine and mine alone

キミはぜーんぶ お姉ちゃんだけのモノ ずっとずっとアイしてあげる [Shell Voice]

This is the first time I’ve seen this movie.

A little bit of SM in the intense play between your brother (you) and your sister (Nanami)!


I want her to like me someday.
You can’t tell your beloved sister directly about your feelings, though.
Maybe it’s because of my boyfriend who goes to the same university as me, but I’m getting more and more sexy every day [big sister].

(Even though I’ve been looking only at her for a long, long timeーー)

You can’t help but feel an irresistible urge to just think about Nanami.

In the meantime, Nanami continues to play with you with her naughty tricks, whether she knows about your tearing feelings or not.
I’ve had people press their defenseless, flabby tits against me. ……

I’ve been hanging around in hot pants, as if to show off my large buttocks and whippy thighs. ……

Even if you don’t have much knowledge about sex, you can’t help it if your favorite (opposite) sex behaves like that.
You’ve been punished for stealing Nanami’s freshly removed pants while she was in the shower.
But you and Nanami were very close siblings.

Yes, until that day came…


How will the love between you and Nanami mingle?
A sweet, sometimes mean, and S-curious older sister – life and sex life with the charming Nanami.

Enjoy intense sex with a sister who is becoming more and more attached to you and dependent on you.
