We haven't even met yet she fucked me in the stairwell

A young woman in a lemon-print top and plaid skirt approaches in a yellow-walled stairwell, smiling at the camera. She drops to her knees and performs oral sex on a man, taking his cock deep while he holds her head. The POV shot shows her sucking and stroking him, then bending over as he grips her hips, her fishnet stockings visible as she takes him from behind.
