Masked Stairwell Flash in Miniskirt

She stands on a pale indoor stairwell in a black blouse, wine-red pleated miniskirt and sheer black stockings, a mask over her face. She unbuttons the shirt and pulls it open, showing small bare breasts and tight nipples, then hikes the skirt to prove she is wearing nothing underneath: a dark patch of hair between her thighs, stockings riding high on her legs. Turning her back to the camera, she lifts the skirt again and spreads her ass with both hands, showing her anus and the full curve of her cheeks while looking over her shoulder. She poses, flashes a peace sign, and finally buttons up as if nothing happened, leaving the tease hanging in the empty stairwell.
