My older sister's friend who comes to stay at my cramped house. My sister and I share a room, but... Moreover, all of my sister's friends have a bad sleep position, and when I wake up in the middle of the night, a ridiculously erotic sight is spreading in front of me. Hami milk, Hamiket are obvious. Do nothing in this situation! That is unreasonable. But in fact, I'm seduced by my sister's friend who is half asleep.
