Seven Days With My Yandere Sister!

OVERVIEW

Spending Seven days with my sister Yandere!

For a week, your parents are away. A modest, peaceful home. Only you and her.
She is your sister; she is lovely, kind, and unsettlingly fixated on you.

A week that begins peacefully soon turns into something much more perverse.

Her kind remarks conceal shrewd aim. Her grins are too persistent.

Her love is too intense. Additionally, things begin to break when you attempt to maintain your distance.

What starts out as a calm week swiftly devolves into something far more perverse.

Her kind remarks conceal shrewd aim. Her grins last a bit too long. Her passion is too intense.

Additionally, when you attempt to maintain your distance… Everything starts to go apart.
