Rina, a Japanese office worker, finds herself alone with a colleague, a thick, juicy cock straining against his pants. She can't resist, leaning in to press her lips to the bulge, feeling the heat and pulse through the fabric. She unzips him, freeing his cock, and licks it from base to tip, her tongue swirling around the head. She takes her time, her hands caressing his balls, before finally taking him into her mouth, her lips stretching wide around his girth. She sucks him, her head bobbing, her tits pressed against his thighs. She pops off, panting, before taking him back in, her hand working his shaft as she sucks, her other hand sneaking up to grope her own tits through her blouse. She keeps sucking, her moans vibrating around his cock, until he comes, filling her mouth with hot, salty cum.
