KGDV-026 - Sisters in the Isolated House: Ravaged by Beasts

This series is structured like a drama and isn't your typical AV. On top of that, the first half focuses on an older aunt character, and Ryoko Sena only appears for two scenes in the second half. She plays a woman on a farm suffering from pneumonia, so the whole thing is quite gloomy. Not really something you can get off to.
