Jun and I have been close friends since childhood. When I got a girlfriend for the first time, when I joined the same company due to a bad relationship, even when I got married and became a married person... Jun whispered and seduced me in her situation (wife) is capable of finding out. Upcoming...! ! My cock gets hard even though I know it's useless! "Isn't having sex with your girlfriend boring?" The little devil's childhood friend and my secret creampie for 10 years.
