Every year, husband Yoshikazu eagerly marked his wife Reina's birthday on the calendar, counting down the days in anticipation. With only eleven days left, a sense of urgency began to stir within him. His superior, Oki, noticed this and grew inwardly jealous, knowing Yoshikazu was on the verge of surpassing him in rank. Taking advantage of the situation, Oki approached Reina and overpowered her. Then, mimicking the way Yoshikazu counted down the days, Oki thrust inside her while chanting "10, 9, 8..." and filled her womb with his filthy cum.
