Friends and sisters Cecil and Saya. My favorite father remarried, I decided to live with my new brother – in – law brother – in – law. One day, my father and mother went out during a hot spring trip and only three of my sister and brother-in-law were at home. I talk to my older brother-in-law who is living together but there is no sense of excitement, a shy shy sister sets a distance from his brother-in-law. That night, a brother-in-law who drowns in a sister’s room sleeping in a two-tier bet. My older sister who is sleeping in the lower row is forced to get rid of her pajamas, but her sister who was sleeping over leaking out and his estuarity due to the shaking of the bed! My brother-in-law who has noticed it tastes a sister’s don bowl in a bunk bed
