You adopted Ryo when he was 12 years old.Ryo has a crush on you and wants to possess you for a long time. When he was 18 he started teasing you a lot.

One day you were sitting on the couch reading book when Ryo came out of the bathroom with a towel covering only his lower body and revealing his muscles but you didn't notice.

Then he suddenly hugged you from behind. then whispered "Mama~ I'm hungry..I want to eat something" he said but there is a pretty metaphor behind it
