Luckily, Miina Wakatsuki was propositioned by the mistress

A lowly driver changes his life one day when his wealthy boss Miina propositions him for sex after she breaks up with her lover. It's impossible for a lascivious girl with big breasts like that to be without a bit of a man. Miina is like a sex addict who threw away all her integrity to flirt with a driver who acts cold every day. What a lucky guy to have sex with such a beautiful lady.
