In the bustling office, M-kun's new subordinate, Ayumi, a kawaii Japanese OL, takes her oral duties seriously. Kneeling under the desk, she expertly teases his massive, throbbing cock with her tongue, ensuring no one notices her late-night overtime. Her skillful hands work his shaft as she takes him deep, her lips stretching around his girth. She keeps him on the edge, only allowing him to cum in her mouth after he's thoroughly satisfied.
