Special 5th anniversary production of "Married Woman's Affair Trip × Married Woman Hot Spring Love Trip." Director Karagi, who fell for a married woman in the previous installment "Married Woman's Affair Trip #146," returns with a special project pursuing that same woman. After their last trip, her attempts to discuss things with her husband fail, leaving their marriage strained and awkward. Upon arriving at the inn, she hesitates when approached at the outdoor hot spring, but eventually succumbs to temptation and gives in. Their bodies entwine again after dinner and once more the following morning, losing themselves passionately in each other's arms. The man gently checks in with her, asking, "Does it feel good?" and as he nears climax, she skillfully encourages him, saying, "Come inside me completely," showing her deep understanding of his desires.
