I didn't even know that the normally unfussy teacher was so bristle. The last school trip before graduation. Yamada, a problem child who had fallen into school refusal, participated only to make memories with his teacher, Usui-sensei. Stunning boobs that you can see even from the top of your clothes. A smile full of motherhood that always makes me kind. I want to make things with just my body. Yamada, who was alone with Usui-sensei, who had been waiting for him, was driven by passion and hugged him in a hurry.
