My childhood friend, a mourning woman who is extremely cute but still has no love experience and stays at home, and I, who was working in Tokyo and came back to my parents' house during vacation, meet again. When I went to her home for the first time in several years, I happened to see her masturbating... I secretly had a crush on her, but I got so excited that I couldn't hold back and forced myself to fuck her...That's when my girlfriend, who has very little experience in love, started having sex with me.
