From the very beginning, the scene unfolds with intense, visually stimulating action. The cowgirl position is depicted with a focus on her ass, portraying an almost maddening passion. Minoru, the son, had been tormented by the alluring curves of his stepmother Elena's perfect backside in their daily life together. Her entire body was captivating, but especially her ass—its natural movement, even during simple actions like cleaning, deeply stirred Minoru's emotions. When she unconsciously reached up to wipe the shelves, to Minoru's eyes, it looked just like she was riding him in the cowgirl position, thrusting rhythmically. This sight further agitated his heart and inflamed his desire.
