Your physique feels odd, Onii-chan…” A lotus flower makes its way to a rural farming village at the behest of a relative, in search of a part-time job. Aoi, with whom they used to bathe in their younger days, is now a grown woman with a tantalizing body. However, being born and brought up in the countryside, these girls have limited knowledge of sexual growth. Despite this, they openly invite the lotus to bathe with them, share their more.. beds, and not be afraid of men! This is the story of naive country girls who are unfamiliar with the ways of the world.
