Although Dave did receive satisfaction from helping her, he did find the whole situation rather hot. Seeing her use that thug as nothing more than a top was a fantasy of his, so he feels that he can't not act on it. He decides to approach the girl and see if is a prostitute, as forcing her to screw with the book is really no different than what the thug was going to do.
Popping out from behind the garbage can, Dave approaches her. She's distracted at the moment, observing herself in the new top. He can't help but stare either; the previous top had fit her well, but this thing was amazing. Her tits fit so snugly in the halter that it was as if her skin had been replaced. The cleavage even appeared deeper, despite being nearly the same as the other top. Aside from her breasts, even her back seemed to take the outfit well, as she was able to conceal the straps tie behind her medium length blond hair. It's as if the outfit was made for her, in a way. Nervous to speak up to the beautiful woman, she finally notices his approach and takes the initiative herself.
"Hey there sugar, what brings ya to this part of town?" she says with a hint of seduction. Her eyes lock on his work attire, causing them to light up. "Oh ho, a business man? I know why you're here. Looking to blow a little steam during lunch?"
"Um...yeah, you could say that" Dave meekly replies. The strength of his libido was nothing compared to his weakness around pretty women.
"Well, you're in luck!" she pipes as she begins to squeeze her tits "I'm in a great mood, and my girls here are eager to make your lunch fun. How much ya got?"
A stark realization hits Dave as he realizes he forgot his wallet in the office. Buying a prostitute wasn't in his game plan, so he had only about ten dollars on his person. He explains to the girl, but rather than turning him down she comes up with a plan. She walks over to the pile of clothes that were once the thugs and claws through his pockets. A tight mini-skirt barely covers her well-rounded ass and he can't help but stare. Her search is rewarded by a wad of cash, presumably taken from other streetwalkers. She seductively saunters back and hands Dave the cash, telling him to pay her with that. With the payment issue of the way, she pulls him behind a dumpster and begins her work.
Kneeling before him, she unzips his pants and is greeted with his erect cock. Wrapping her hand around the base, she guides his member between her soft tits. She decided to try something new, opting to leave her top on as to let the fabric massage as well. Dave is skeptical, but the pleasure he feel as she presses her tits together quickly erases any doubts. She begins slowly pumping, moving her tits up and down the shaft in a powerful and repetitive manor. The pace increases further and further, sending waves of pleasure through him. As this begins to mount, he hears the thug's thoughts. As usual, he's in hysterics, realizing his role as nothing but a prostitute's assistant. This musing is quickly broken when she takes it to the next level. Leaning her head forward, she begins to lick the tip of Dave's cock. Her saliva acts as a lubricant, making the sensation intensify even further. Yet still he holds back, even when she plunges the entire of her mouth onto his rod in an effort to bring him to climax. As it turns out, its not her acts that bring Dave to climax, but her assistants.
A weird change had occurred. As stated, the halter initially opposed the idea of being nothing more than an item. Thoughts such as "Oh god, this is horrible" were the norm, but now it is the opposite. "I hope I'm working out right...Am I supporting owner's tits well enough?" are all he can hear. Hell, even the tone has gone from deep and manly to light and girly. The concept that he went from a thug to nothing more than a mindless object for this woman to use was too much, and he finally comes.
She isn't expecting the orgasm so soon, so he's able to shoot of a few spurts before she gets the rod back in her mouth and swallows the rest of it. Fittingly enough, the small amount on her cheek drips off, landing on her top. After resting in ecstasy for a few moments, he hands the woman her cash and walks off, leaving her and the "assistant" to do their work.
