NACR-239 Mitsuki Nagisa, a sex worker who keeps getting creampied by her unfaithful father and otaku brother

My name is Mitsuki. - I live with my father and brother. - My father used to have a serious personality and was very close to my mother. - Then, due to an accident, my mother suddenly passed away, and I think her ``love'' towards us became distorted due to that loneliness. - And before I knew it, I started working with my father.
