An old teacher and a student, Yui. The moment I saw Yui cooking at my house from behind, I hugged her. Fingers stuck in breasts, mucus like a flood... I can't go back anymore. Spring, summer, autumn and winter, I will leave a year spent with Yui .... Yui, who has a sensitive constitution, becomes an old teacher's sex processing doll and greedily feels pleasure.
