Yuuna went missing when she was little. After a few years, she was taken in by a relative and became an expert in erotic matters. She has the ability to repeatedly beg for what she wants, something typical of young girls, and rides the old man's dick with her insatiable pussy. She seduces him and makes him erect, demanding his man juices so she can make a baby! She is a girl who knows nothing about wanting to be ejaculated from morning till night!
