Reira was unknowingly captivated by Shiho, the older sister of her husband, Daisuke. When Daisuke went on a business trip, Reira invited Shiho to stay at their home, causing their relationship to rapidly deepen. Shiho skillfully used words to draw Reira in, gradually seducing her with a mix of tenderness and boldness. Though hesitant at first, Reira found herself increasingly entranced—her breath quickening as Shiho claimed her lips and entwined their tongues in a lewd, sensual dance. Their bond grew hotter by the moment, touching each other's intimate areas, their aching bodies instinctively craving deeper connection, forging an intense, passionate intimacy between them.
