Disorder of a drugged sister!

Welcome to pure love acme heaven!
I live with my little sister, just the two of us.
Since our parents left this world, our relationship has changed.

We embrace at night to distract from the loneliness.
That act deepened our love for one another.
Soon our acceptable embraces became more explicit.
Because we loved each other, because of love...

From today, we cease to be brother and sister.
From now my little sister is my lover, my wife, my pet, my servant, my sex toy.
