This AV features a novel setting where a seemingly innocent volunteer group is actually an erotic volunteer group seeking male sperm, with a gap between appearances that's irresistible. The solo parts of Matsui Hinako and Kashiwagi Konatsu focus on bathroom and sitting positions, especially Matsui's cute back-tied hairstyle, her cheerful personality, and her petite yet elastic erotic body being highlights. While the main 5P scene is impressive, the solo parts are equally enjoyable. The work as a whole shines with Enachi's genius acting, Konatsu's beginner yet fully unleashed sexiness, Akari's sexually liberated charm, and Hina's little devil-like cuteness, with everyone performing at a protagonist level. As a harem piece, it's waste-free and continuously erotic, making it a divine work. Its high completion makes it a top contender for this year's number one spot, with ample individual erotic scenes. The overhead angles showcasing breasts and pussies are breathtaking, with a relentless combo of erotic scenes that's hard to look away from.
