MOON-057 Miyu Aizawa drowns her married neighbor, who can't be penetrated, in a 'saliva marking affair'.

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.
