A long-serving, respected senior female employee at the company married a younger coworker and left her job happily. To celebrate the promotion of her husband's boss, a party was held at a colleague's house. Although the couple was invited, her husband had to attend an unexpected business trip and couldn't come, so the married woman attended alone. However, that trip was actually a setup orchestrated by the department chief. Ever since she worked at the company, the chief and her coworkers had been coveting her as their beautiful married target. Unaware of the trap, she arrived at the party, gradually got drunk, and as her pent-up desires intensified, she began to feel pleasure building—eventually climaxing repeatedly.
