Natsu Igarashi is alone with M-kun, the first slut documentary work that is rolled up! Immediately after meeting, it starts with lovey-dovey sex, taking a bath, getting tipsy while drinking alcohol, late-night dates, staying at the hotel until morning, and so on. Be captivated by Nacchan, who is too erotic to whisper in your ear and blame you for stopping and chikubi! Have the best time until the moment you check out.
