While visiting the neighbors to say hello, she discovers that the man she meets is the mastermind behind the biggest stain in her life, her crime, and her ex-boyfriend. As they pass each other in the hallway, he blackmails her with stories from the past, and she falls from the height of happiness to a nightmare. She wants to move right away, but she can't easily say it about her mortgage. Her past, which she doesn't want to remember, comes back to her, but she can't resist, and she becomes a submissive sex pet at the man's command. Even though her husband is right next to her... and she knows he's unfaithful... she cums over and over again on the dick of her ex-boyfriend, who is a perfect match for her. In the midst of an immoral orgasm, she gradually falls into pleasure as the neighbor fails to get her money.
