Several years had passed since their wedding, and the warmth in their marriage had long faded, replaced by a cold, monotonous daily life. Yuna, the wife, had gone without intimacy with her husband for a long time, enduring dull days with little excitement. Then one day, her husband suddenly suggested a hot spring trip—a rare invitation that sparked hope in her heart. Eager to break free from their stagnant routine, Yuna happily agreed. On the day of the trip, she arrived at the inn with quiet anticipation, unaware that her husband had prepared a plan far bolder and more sexually charged than she could have imagined. Without realizing his true intentions, Yuna was led into an entirely new and arousing experience.
