She can't stop her hands

Her hands betrayed her first, moving back to her oh-so-accessible pussy and breasts. A nipple pinched between finger and thumb, her spasming pussy clenching tightly against two of her fingers, she sank back against the wall of the alley, frantically frigging herself for everything she was worth. The sheer rush of what she had done, was doing, thundered through her. A raging fire blazed in her needy loins, one which she sought to fulfill as soon as possible. The rhythm of her hands, the thunder of her heartbeat, drowned out the crowds around her, isolating her even as she was exposed.

Mark had watched her slip off into the alleyway, quietly positioning himself to watch her come out. The ongoing modifications of her shirt intrigued him, and he had quite a few good photographs of her, including down the side of her dress, now. His gaze continued to watch the alley, idly wondering when she might step out, when a pair of dirty bare feet appeared past the dumpster she was behind, pressing hard against the rough concrete of the alleyway.

Was she masturbating? He had to see, and he headed across the street quickly, before making sure no one saw him enter the alley. As he rounded the corner of the dumpster, he could see Julie, her shirt even smaller and more ragged now, frantically pumping her pussy with both hands now, lusty moans tearing the air. She was incredibly lucky the parade was in full swing, its noise drowning her out from the entrance of the alley.

He caught several more pictures of her, her tattered "dress" concealing nothing, her hands covered in her juices, a puddle forming beneath her. He watched as she reached climax, arching off the ground and screaming her primal pleasure as she bucked against her hands. That might have been heard from the street. He turned to slip away, as Julie slumped, spent and delirious, on the ground, her head rolling to the side as she dozed.

Mark wondered what would happen if someone came back here and found her. That ought to be good film, though he did worry about her getting caught by the police. He wanted her to himself, and her being stuck in a jail cell didn't help him at all.
