A beautiful woman who boasts super long hair that is 3 meters long. My occupation is a hairdresser. She loves her boyfriend dearly, but is extremely jealous. I shampoo my long black hair every day to show my boyfriend how clean and beautiful it is. Aiko is beautiful and her very long black hair is very attractive, so some of the customers who come to the store are male customers, but she only cuts hair for female customers. Also, she never lets men other than her boyfriend touch her long black hair. On the other hand, she wants her boyfriend to touch and play with her long black hair every day. For some reason, Aiko finds it extremely pleasurable to have her boyfriend touch and hold her long black hair. Aiko has a strange tendency to feel pleasure when she has sex with her boyfriend unless she wraps her long black hair around him. On the other hand, when Aiko's hair touches a man other than her boyfriend for some reason, such as on a crowded train, Aiko feels unbearably uncomfortable.
