MUDR-106 An honor student who pretends to be a plain person. A real copulation between a girl who loves her uncle so much that she can't maintain her rationality because she loves sex so much. - Koharu Sakino

I like reading. - I also like studying. - Koharu is a plain and serious honor student in class. - But in reality... she was a lewd girl who loved erotic fantasies and loved her uncle...! - ``Uncle, shall we have lots of sex today too?'' As soon as the two of us are alone, we have sex all day long with the gap-type girl who shows off her erotic, carnivorous face, which is completely different from her usual appearance! - For 230 minutes, she seduces the old man with her long, naughty tongue and fucks him with her delicate, white, sensitive body until his sexual desire is exhausted.
