Growing up I was a sickly child and due to this my parents designed an experiment to attempt to help me improve my immunity by hugging my sisters for extended periods each day. Eventually this ended up growing into more than hugging as the closeness to my sisters stirred up feelings from within that I just couldn't ignore.

Kohaku dutifully does the house chores but after a "hug" with her sickly older brother, things could never go back to how they were.

Today's hugging partner is the super feminine Akane!
