A one-night, two-day mini-trip with an uncle to a secluded hot spring inn. Haruna-chan, who dreams of working as an editor of French literature at a publishing company, and Sachi-chan, who aspires to be a public servant and has a physique that looks like a female college student. Taking advantage of the absence of guests at the inn, they change into uniforms and have sex in the corridors, or force each other to wear leotards and stroke their penises, all while being adorably charming girls with lovely smiles. Watch as, because it's just the two of them, they show their true faces and gradually grow up.
