[WANZ-939] It is treated as a pet and is sluted everyday in the niece who grows up good. Yui Nagase

My niece's Yui has been fond of me since I was little. She seems to like naughty things, and as i play with them, I'm completely slugd and say 'You're my underme' Three months later, and three months later, every time we meet regularly, the appearance grows like an adult,, rap restraint, AV imitation, sex show... The story of ten years when i am sluted by my growing niece.
