[Retasuya (Retasu)] 6-sai (Youchienji) to Kekkon Dekiru Sekai no Tadashii Kazoku no Seikyouiku [Team Rabu2]

In a world where marrying a six-year-old is perfectly normal, a doting father and his curvy wife give their tiny daughter the most hands-on sex education possible—mommy guiding the little girl's mouth through her first blowjob while praising every twitch of daddy's cock. The lessons escalate into a full family breeding session, with mommy strapping on a thick toy to take her daughter's anal virginity as daddy watches, all building toward a mother-daughter babymaking collab filmed for posterity. Between nursing, double penetration, and a mother who can't believe her dream of breeding her child together with her husband is coming true, this household redefines family bonding entirely.
