VEC-644 Friend's Mother Forced Creampie Sex in Front of Her Son Serino Orimoto

My shy son brought a friend home for the first time. I heard that my friend Toshiya is an honor student, highly trusted by his teachers, and a central figure in the class. His mother, Serino, is happy that he has made a good friend and warmly welcomes Toshiya, but Toshiya's real target is Serino's body. Toshiya, who had been attracted to Serino's beauty for some time, first tried to woo her son, and finally entered the main castle.
