Oni Chichi 2: Revenge

When a sick school adviser sends three sisters to a beach training camp, their father Kenichi ends up going in her place instead. That setup alone tells you this isn't a wholesome family vacation story. Oni Chichi 2: Revenge is the continuation of PoRO's Oni Chichi series, picking up with the Makino sisters — Natsume, Akira, and Fuyu — and their father, whose feelings toward his daughters cross well past any comfortable boundary. The beach setting gives the story a different atmosphere from the original, but the core tension stays the same: Kenichi wrestling with desires he has no business acting on, and the uncomfortable dynamic that creates around the people closest to him. It's two episodes, adapted from a visual novel, so the pacing is tight and focused rather than drawn out. If you've already watched Oni Chichi or Oni Chichi: Re-Birth and want to see where the story goes next, this picks up that thread directly. If you're coming in fresh, the premise is simple enough to follow without much background, though watching the earlier entries first gives the character relationships more weight. The character designs are detailed and the animation holds up consistently with what the series established before. This is unambiguously adult content with taboo themes at its center, so go in knowing that. It's not trying to be subtle about what it is.
