In a crowded office, busty colleague Karen can't focus on her work due to the constant grinding of her ass against her chair. She surreptitiously touches herself under the table, her massive tits jiggling with anticipation. As the day drags on, she grows bolder and starts playing with her pussy lips through her panties. Finally, when everyone has left for the day, she unzips her skirt, revealing a lacy thong and a shiny pink plug nestled in her tight asshole. With a moan of desire, she removes the plug, preparing for the ultimate taboo act with her colleague's huge black dildo she's been hiding in her desk drawer. Stretching her sphincter, she cries out in pleasure as she sinks the massive toy into her ass, filling her up to the brim with unadulterated joy.
