After successfully closing a business deal, Aoi and Hasegawa planned a celebration at Aoi's nearby home. That evening, Aoi's wife, Reina, welcomed them with her stunning big tits, causing Hasegawa to involuntarily sigh in awe. As the night deepened and alcohol flowed, both men grew increasingly drunk and dizzy. A minor disagreement sparked a heated argument between them, barely avoiding a physical fight. Overcome by jealousy toward Aoi and fueled by intoxication, Hasegawa could no longer resist and reached out to Reina.
