Behind Closed Doors episode 3


“Kenichi” walks around the mansion looking for his lover “Yoshino”, and is told by a man who was in the basement, “You should go up the spiral staircase.”
What I saw there was the appearance of “Yoshino” who was jointly trained by “Michiru” and “Anna”.
Kenichi was confused when he saw his lover being humiliated, but Kenichi, who once learned the taste of teasing, couldn’t control it and started training himself.
Furthermore, that alone is not enough, and even “Anna” and “Yasue” are trained.
