Nanami Misaki's parents divorced when she was a child, and then her mother remarried to another man, a depraved man who made my memories unforgettable of the terrible things he did to Nanami. She ran away from home to go to the city to live, got to know her lover and lived with him, and the two were also about to get married when suddenly one day he appeared at Nanami's doorstep. Her husband didn't know anything, only knew that he was Nanami's stepfather, so he opened the door to pick him up and gave him a warm reception, he didn't know that when he left the house, everything happened to Nanami again.
Although Nanani hates him very much, why does she constantly orgasm when she is forced by him...
