[Tomozawa Shou] Watashi to Papa no Maji Soukan

Brief synopsis (First story): A man knocks up his young daughter. She has a Son. The Mother is a shotocon & accidentally becomes pregnant. The Mother has a Daughter this time. Daughter is raised normally, thinks older brother is just her brother. There is mutual sexual attraction between brother/father & sister/daughter but try to fight it, poorly. (Precocious puberty runs in the family, I guess.) Sister gets caught masturbating, brother goes "fuck it", jumps his sister (and does). Brother confesses he's his sister's father in the middle of coitus. Sister is overjoyed she has a father. Brother/sister sex scene turns into father/daughter sex scene mid-stroke. Mother sees her children in the act, but turns a blind eye. Daughter is aspiring Idol. Some shit goes down. Daughter enters a local talent show. For some reason father confronts daughter on stage. Proceeds to have a live sex show in front of audience, letting all know they're brother/sister & father/daughter. Happy ending.
