Teacher Azusa and the Yuu which act in the same workplace. Lesbian Couple to keep company with co-workers in Naisho. When I begin to live together, and two years passed, feel mannerism in SEX with the Azusa, and the Yuu which is frustration begins to learn a thrill and Koufun in Koto played with by a schoolgirl…. The Yuu thought that women did not become fickle, but after all, wherever of the Kokoro, felt debt in Azusa…. But, the Yuu was fuddled with stimulating Nichijou so as not to be able to move back anymore.
