Yukari spends her days playing alone because her husband is busy with work. As she consoles her unsatisfied body today, Hiroki, who lives in the neighborhood, comes over with a travel souvenir in hand. Hiroki, who was concerned about Yukari not locking the door despite her carelessness, came to call out to her, and what he saw in his eyes was Yukari's lewd behavior. Yukari immediately approaches Hiroki with her breasts in order to calm him down, who panics due to her unexpected situation. ``If you'll keep it a secret...I'll have a deeper relationship with you as a neighbor.'' With her big tits bouncing and swaying, they quickly move from being just neighbors to becoming a man and a woman.
