Nana&Matsuha (Patreon)

Kanzaki Mamani raped her own daughters Ada Izuki and Ada Matsuru. Nana and Matsuha were born to them, but they used the surname kanzaki.

Both have inherited their father's (grandfather's) strong male abilities, and although their faces are still a little juvenile, they are as capable of pre-phallic breeding as their fathers.

Maybe one day they will surpass their father and develop more powerful abilities.
