Raji, who has always been led around by the nose by his childhood friend Tsubomi Mochizuki, whose blank expression makes it hard to tell what she's thinking. Suddenly asked, 'I have a boyfriend now so I want you to be my sex practice partner.' Raji, who likes Tsubomi, has no reason to refuse and practices sex. But she has a personal rule that 'kissing is only allowed with someone you like,' so she won't let anyone kiss her. She had been expressionless the whole time, but gradually started to feel pleasure and showed lewd expressions and sounds. Rage couldn't hide his emotions...!
