IPZ-501 Honeymoon affair trip The last night and the first night Kiki Aino

Yuuichi, who works at a major trading company, and his subordinate 'Aino' were in an affair. The two, strongly drawn to each other, deepened their relationship over time. However, Yuuichi, who has a family, always returned home on the same day after their trysts, so they had never spent the night together… Their first hot spring trip... Their first night alone. In a hidden inn far from daily life, filled with the scent of hot spring flowers, the illicit passion between man and woman.
