Female high school student's complete domination, twisted love - Ichinose Suzu RBD-626

My sister and her husband's beloved daughter, Rin. She's a girl we all had high hopes for, and I, along with others, have doted on her since she was little. Rin is entering puberty and starting to exude the charm of womanhood. I suppress my feelings and play the role of a good uncle. But I've reached my limit.
