配信者のミユは最近引っ越してきた隣人の男と挨拶をする。人の家庭を寝取りたい女はある日、男を自宅へ呼びキス。SEXをすると「結婚してるから中出しは出来ない」という男に不倫した証拠を体内に取り入れてほしいとキスをして男の体内に唾液を流し込む。それ以来男と会う度に唾液を飲ませたり全身リップをして妻に隠れて唾液マーキング不倫を楽しむ。
Miyu, a streamer, greets her new neighbor, a man who recently moved in. Wanting to seduce someone's wife, she invites him to her home one day and kisses him. When they have sex, the man says he can't ejaculate inside her because he's married, so she kisses him again, letting her saliva flow into his body as proof of her infidelity. Since then, every time she meets him, she makes him drink her saliva or licks him all over, enjoying a saliva-marking affair while hiding it from his wife.
