Synopsis
I have a sister named Kurumi.
Her body may have matured, but her mind is still that of a child.
Today is a day when our parents won’t be home.
Which means it’s just me and Kurumi alone.
With no one to interrupt us, I’ll use the pretense of giving her a ‘massage’ to teach my sexually naive sister all about pleasure!
Your choices will determine whether you bring happiness or misfortune to Kurumi.
First installment of the ‘Innocent Sister’ series!
