grandpa and granddaughter of loricon, mayura hoshizuki.

Mayura, a healthy schoolgirl who keeps taking care of her 75-year-old grandfather "Tetsumaru" who sometimes takes suspicious actions. One day, I happened to witness the first experience of Tetsumaru Mayura... The abnormal behavior of the iron circles is spurred. My grandfather's 75-year-old desire to burn, my cute granddaughter Mayu and others are the services of love.
