On the day without my parents, I was frustrated all day long until my sister and sperm died.

On the day of his parents' absence, 'Kotori' repeats their forbidden incest with his older brother. Do you know your brother? He grows up and gets back to his place again? So, no matter how old I get, I'll come back to my brother and stay with him forever. Today, I ate all day and filled my little bird's chin with sperm from my brother.
