His second wife had two children: an older sister, Asuka, and a younger sister, Marina. Perhaps because they had grown up without the love of their father, they smile and call out to me fondly, "Daddy! Daddy!" They unconsciously and defenselessly stand before me, showing off their budding breasts and clean underwear... One day, the sisters, who had spied on my wife and I having sex, urged me to do to them what they did with Mom. Unable to resist their innocent temptation, I crossed the line... Since then, I have been continuing my forbidden relationship with the sisters, who are adolescent and full of Kokoro, behind my wife's back. "Who do you like better, Mommy or us?" I am at the mercy of the two stepchildren.
