Radka's eyes gleam with lust and greed as she takes the stranger's money, leading him to the grungy toilet stall. Her hands eagerly unbuckle his belt, freeing his stiff cock. She teases his tip with her tongue, tasting the salty pre-cum, before swallowing him whole. The stranger's hands tangle in her hair, guiding her head as she bobs up and down, her moans vibrating along his length. The toilet stall walls shake with their fervent fucking, Radka's spit dripping onto the floor, echoing the filthy, exhilarating encounter.
