Iinari Aneiro ~Onee-chan sae Ireba Ii!~

Ane, aneki, onee-chan, that guy... everyone calls her different names.
But to everyone, she's still just a woman.
It suddenly happens one day, in the middle of an ordinary day!
You start seeing her not as your sister, but as a woman!

Once you start seeing her as a woman, you can't see her as the sister you knew before,
anymore.
And the twisted emotions that begin from there grow more and more intense, hotter and unstoppable, and eventually become an uncontrollable impulse that drives you to action.

Iinari Aneiro is a collection of immoral stories that everyone may have experienced at least once!
