Kaeri no Kai no Sonogo wa... ☆1 Nen, Nama de Tannin no Sensei to Sex Shiteta Onna no Ko no Naisho no Nikki☆

Her name was Yuka Tengu. In class they were teacher and student... but when they were alone... Dec 23 To commemorate their secret one-year affair, she lets him see her diary. All the things they've done this past year... all the joys and worries, pleasures and shames... Her bewilderment of sexual discovery is documented in detail. The pain of her first time... When someone her delicate age should be doing no such thing... Her small body the continuous recipient of teacher's much wanted attentions. Because she loved him.
