I was a virgin and an ordinary college student, and I decided to live alone and moved in with a friend. Excited about her new life, she is approached by Nao Mr./Ms., a married woman who lives in the house next door. I gave him a simple greeting, but my eyes were glued to the protrusion of Nao Mr./Ms.'s chest that could be seen through the thin loungewear, and I don't remember anything about that time. A few days ago, I indulged in masturbation thinking about Nao Mr./Ms., and when I went out, I encountered Nao Mr./Ms. dressed like an esthetician.
