The reason a married woman goes on a hot spring trip is because she's troubled in her relationship with her husband. Although she should know his routines well, having worked at the same company, lately he's been coming home late and acting cold toward her. To her surprise, her husband showed no interest when she left for this rare trip. During her journey, she receives a message from him about his return time, driving her into despair. Giving in to her emotions, she turns her gaze toward a man she's just met. Locking eyes with moistened gazes, the two passionately crave each other repeatedly, and she begins pleading desperately to be thrust into harder and deeper. Even as they're wrapped in warm steam, waves of love continue swelling deep within her heart.
