[Big Ass Female Slave●][Anal Fully Exposed] Aika Yamagishi, the company president's secretary, learns that her husband, who works at the same company, has received a layoff notice. Concerned about his declining performance, she approaches the president for help, only to be demanded sexual favors. She chooses to endure it, thinking, "As long as I can bear it..." But her body involuntarily responds to the older man's intense, relentless thrusting that doesn't end after just one or two ejaculations. Unlike her emotionally distant husband, the president's roughness makes Aika's ass clench and spasm as she repeatedly reaches orgasm. The highlight is watching her big ass sway late into the night during secret overtime, desperately begging for cock—something she could never confess to her husband.
