Yui Watanabe, a Japanese OL with a secret, uses her sexual prowess to alleviate work stress. Today, she targets a young, impressionable coworker, leading him to a private corner. She unbuttons her blouse, revealing her lacy bra and large, firm breasts. He watches, mesmerized, as she unzips his pants, pulling out his hardening cock. She takes him deep, her mouth and hand working in tandem, her saliva glistening on his shaft. He returns the favor, fingering her wet pussy through her thin skirt before fucking her vigorously. She clings to him, her orgasm building, until he pulls out, his creamy release painting her backside.
