Ayaka Makimura, a voluptuous mature woman, appears on the Fitch carnal label. Her overwhelming mature body and pheromones make arousal unavoidable. One holiday, Yuzuru returns home to find his father has remarried. Ayaka greets him with a smile, but Yuzuru's eyes are drawn to her curvy figure, making him visibly flustered. Afterward, his father begins his usual game of shogi, and Yuzuru goes to the refrigerator for a drink, but his gaze becomes fixated on Ayaka's ample backside.
