Momoka, a Japanese OL, can't concentrate on her work, her pussy throbbing relentlessly. She excuses herself, striding to the restroom, her high heels clicking on the polished floor. Inside, she locks the door, leaning against it, her breath hitching as she hikes her skirt up, revealing her panty-clad pussy. She rubs herself, feeling the dampness seeping through. Her fingers trace the edge of her panties, pushing them aside to expose her swollen clit. She circles it, gasping, her other hand cupping her breast, pinching her nipple through her bra. Her fantasy takes over, envisioning a colleague walking in, pushing her against the sink, and fucking her brains out while she's still dressed in her professional attire.
