Chaste and Teased...Forever

The woman on the screen was intensely gorgeous, an Asian woman with a stunning figure and large breasts. Her eyes dug into Sarah's soul, and all Sarah could think about was how absolutely wonderful it would be to serve that woman, give her pleasure...maybe get some pleasure of her own...
Thousands of videos rested in the massive external hard drive hooked to Sarah's computer. Audio and text had their own representatives, too. Three times a day, Sarah linked up to the drive and watched a video, listened to an mp3, read something, or viewed a slideshow. It made her horny to do so, which caused her to rub and caress the skin near her nonexistent chastity belt, and that made her more submissive every time she did so.
Sometimes the files had subliminals added in, sometimes not. She always wore her collar during these teasings, so any suggestions in the text she read were taken as gospel. Sometimes they were quite extravagant...
One that had taken deep root was her addiction to oral sex. She was becoming known for her love of this, and often received calls during the evening. Several men and a few woman would call her and say "It's a shame you're not here right now." Sarah would then find herself on the road to wherever the right place was, and sometimes would find herself going down on everybody present...
She was an absolute slut, and she knew it. The files told her so. Her purpose in life was to bring pleasure to others, and she did this with absolute enthusiasm. She ached deeply, wishing in the small hours that she could come, even once, but the thought of coming triggered deeper addiction to the chastity she now masochistically enjoyed.
Sarah didn't know that there was no external hard drive; there was only her imagination of what would make her horniest at the time. There was no keyholder for her 'imaginary' chastity device; the curse had bitten so deeply that she would actively resist its removal.
All she could be was horny and submissive, at the beck and call of any who demanded. She confided the trigger easily; it was part of her compulsion. Once her many lovers came to understand this, they seldom lost time taking complete advantage of her--which was what she had wanted. Perhaps not before, but now? She wanted it with all her being. The files told her to.
Sarah's phone beeped, and when she viewed the incoming text, it was the trigger she'd been waiting for. Phone, purse, keys, accounted for. Heels, stockings, no panties or bra--they were forbidden--and in nothing more than a long jacket and said accessories she stepped into her car to head to a 'friend's' place to service a party of twelve. She'd be there in twenty minutes, and stay for hours as she was used over and over again in ways that once upon a time would have made her run like hell.
There was no way to change what she had become. There was no way she would ever orgasm again. And every day she would tease herself further, every night she would give others the pleasure she would never again experience.
She had done it to herself, but she had no idea of the other players involved...
