Sneaky Masturbation Finger Fuck Whilst Urban Exploring!

A woman sneakily fingers herself while exploring an abandoned building, her fingers sliding in and out of her wet pussy as she moans in pleasure. Suddenly, she hears a noise and freezes, heart racing. It's just a stray cat, and she relaxes, resuming her self-pleasure. She then spots a hidden passageway and decides to investigate, curiously venturing deeper into the darkness. As she feels her way along the walls, her fingers brush against something hard and long. It's a cock! She gasps in shock but also arousal, gripping the shaft. The owner of the cock reveals himself - a dirty, old man who's been hiding there watching her. They agree on a dirty deal; he'll let her leave unharmed if she services him right there. She reluctantly kneels before him, sucking his cock, her eyes filled with fear and disgust.
