Sayoko Kuroki, 42 years old, who has been married for 15 years, lives with her husband in a housing complex. A sexless and frustrating day. One day, the man next door catches him peeking, and he is frustrated. Sayoko masturbates in front of me and escalates with handjobs and blowjobs. When the man's brother finds out, he surpasses Sayoko for revenge.
