Masked woman masturbates on public stairs

A masked woman in glasses and a sweet floral dress sits on a public stairwell like she has all the time in the world. White lace-top thigh-highs, burgundy heels, skirt hiked — she spreads her hairy pussy, shows off a jeweled green plug buried in her ass, and starts playing where anyone could catch her. She holds herself open, fingers her wet cunt, and rides that plug with a teasing little bounce, one leg kicked up so the heel dangles. Dress bunched, mask on, no panties — she keeps spreading, stroking, and showing everything until the concrete stairs look filthy.
