Kana-chan's eyes, which at first scream "It's disgusting! Stop it!", gradually become hollow...``What the old man said... everything was right...'' His brain melted, his strength and reason to resist disappeared, and he fell to the point where he lifted up his skirt, slid down his pants, and showed his young crack.On the seventh night, it completely collapsed.
