Natsu Igarashi is alone with a Maso-kun, her first slutty documentary work! Immediately after meeting, it starts with flirty love SEX, taking a bath... getting tipsy while drinking alcohol... late-night date... morning. Until at the hotel...etc. Be captivated by Nacchan, who is too erotic to whisper in your ear and torture you to stop and torture her! Have the best time until the moment you check out.
