A man named Koumatsu An becomes nervous when faced with Arisu Saotome, a woman so feminine she could pass for a girl. This encounter marks both their first experiences; Arisu's first time dressing as a woman and having lesbian sex, while Koumatsu has never been with an "otokono kanojo" (woman who looks like a girl). As they become more comfortable, Koumatsu brings beer and begins to act flirtatiously. He undresses Arisu slowly, exploring her body with kisses and licks before moving on to oral stimulation. Despite his initial hesitation due to being drunk, he performs well enough that they are able to proceed with intercourse. Throughout their intimate encounter, Koumatsu expresses admiration for Arisu's unique physique and enjoys every moment of their passionate lovemaking.
