Summer Scent

It's the beginning of summer. Jack is 18 years old and has just finished high school by graduating.
He has a tense relationship with Eve, his sister who seems to have disliked him cordially for a few years.
Jack's parents having left town for a week, Eve invites her best friend, Cassie, to join them.
They have the house and the pool for them alone.
How Jack will handle the situation depends on you.
