VEC-554 Mother's Best Friend Miku Kitagawa

My mother's best friend, Miku, will take care of her in place of her mother who is going on a trip. My mother's best friend is just an old woman. Daisuke wasn't expecting much, but what appeared before him was a busty beauty far beyond his imagination. Daisuke can't stand the thought of being alone with Miku for a while, so he sneaks into the bathroom to take a look at Miku's underwear.
