Shinsei: Futanari Idol - Dekatama-kei!

Climbing Japan's cutthroat entertainment industry, two girls are carrying a very particular secret beneath their idol personas. Riko wants to be queen of the idol world, full stop — she's ambitious, loud about it, and not slowing down. Mizuho takes a softer approach, genuinely devoted to making her fans happy in whatever way they ask. The twist is that both of them are futanari, and the show leans into that premise completely rather than treating it as a background detail. It's a 2-episode OVA from 2016, adapted from a visual novel, so it's short and doesn't pretend to be something it isn't — this is hentai with an idol-industry wrapper, and it commits to that combination with some actual character personality behind the two leads. If you've watched Futabu! or Futa Club and wanted something with a bit more of a competitive, spotlight-chasing energy, this scratches a similar itch. Futanari Densetsu fans will also find the character dynamic familiar. The idol setting gives it a specific flavor that separates it from more generic entries in the genre — there's ambition and rivalry baked into the premise rather than just scenario after scenario. Don't go in expecting deep industry drama, but the personalities of Riko and Mizuho are distinct enough to give the thing some texture beyond the obvious. Short, specific, and knows exactly what it is.
