Natsumi Igarashi's first documentary as a naive girl, spending time alone with M-kun, showing her true self! Starting from instant love and sex upon meeting, then taking a bath... drinking alcohol and getting tipsy... late-night dates... staying at a hotel until morning... and so on. Captured by the overly erotic Natsumi, who whispers in your ear and teases with light restraint and tickling! Enjoying the best time until the very moment of checkout.
