"I'll give you lots of love for the next three days."
Shirase Yurika. My brother and his wife's only daughter, and my niece.
It's become an annual tradition for me to look after her for three days when my brother and his wife come home from work.
She's a shy, quiet girl with few words.
But the moment she's alone with me, she shows her true colors...

"Look, these are the legs of my favorite young girl."
She presses her sweaty white socked feet against my face and laughs like a little devil.
Our relationship began three years ago, when she saw an adult video I had in my house.
As she mocks and blames me, I pathetically spit out my white semen.
My three immoral days with my niece begin again this year...
