In a group of friends from the 3rd class of 6, with a challenge of '1 million yen prize if you can kiss!' Aohishino-chan also crashes in, leading to a thick development in a 3P lesbian scene!? While saying, 'Girls together...,' they kiss lightly, thinking it's just a joke, but then, 'Huh? This feels kind of nice.' Kisses on the lips, underarms, nipples... even on the private parts!! Kissing turned out to be the switch for sexual desire.
