Chika (28) is a married woman working as a beautician, living with her serious and honest husband. Now in their third year of marriage, she finds herself suffocating under her husband's strict control, with no freedom and a life filled with stagnation. Wanting children but unable to due to mismatched schedules, their intimate life has dwindled. Desperate to escape her oppressive daily routine, she embarks on a trip. Hoping to rekindle her husband's interest, she gives in to a stranger's advances, allowing him to fondle her in a mixed-gender bath. As his cock penetrates her, she writhes in ecstasy, lifting her upper body and grinding her hips on her own, then crying out in pleasure as he takes her from behind, fully surrendering to the sensation. Her actions reflect a married woman breaking free from restraint, chasing new desires.
