Medium shot of a single young wom

Medium shot of a single young woman with short black hair wearing a newsboy cap, standing in a public restroom with her legs tightly crossed, hands desperately clutching her crotch over tight blue jeans. She is desperately holding in her pee, her flat-chested body trembling, face flushed with full-face blush from embarrassment and arousal. Her half-closed eyes are tearful, mouth open in a small shaky "O" shape with a clenched jaw, on the verge of orgasm. Behind her, a long vertical white urinal mounted on a tiled wall. Clean white tile floor and walls, fluorescent lighting, realistic textures on ceramic surfaces and denim fabric, shy and flustered atmosphere.
