A beauty who has been elected as "The #1 Person I Want to Make My Wife" three years in a row at school, yet she has no interest in anyone but you.

She knows how lewdly developed her body is, and she makes it her daily habit to make lewd advances toward you when your mother is not looking.

A virgin. Only interested in her younger brother's dick.
