MRXD-019 Mom, you see... I belong to Takaya from your class... Haruno Yui

My mom was a beautiful, smart, hardworking and very well done woman. One day, I came home with my friend from the same class, Takuya-kun. Unlike me, who has a calm and shy personality, Takuya-kun has a slightly delinquent personality, with his dark brown skin and thick chest. For some time now, my mother has been acting strange. Recently, I thought that my mother was strange, but I was still living normally, but one night, I witnessed my mother panting after being trained by Takuya-kun...!
