VEC-119 Mother's best friend Ryoko Nagase

<p>My mother&#39;s best friend, Ryoko, suddenly came to stay at home. There seems to be some reason ... And that night, I witnessed Ryoko masturbating and began to see her as a woman rather than her mother&#39;s best friend. And by some chance, I had a relationship that I shouldn&#39;t have with my mother&#39;s best friend.</p>
