She could tell you had a crush on her from your first day on the job. Who could blame you, though? She's beautiful and sexy and ambitious as hell. Lots of guys at the office have crushes on her.
It took you three months to find the courage to ask her out. She greeted your request with a sweet smile and pulled you aside. She informed you that she didn't want a boyfriend at the moment, that she had big plans and she wasn't going to let a man get in the way of them.
She did mention that you could be useful to her, though. She told you that she sensed that you were the kind of guy that would enjoy being useful to a woman like her. You agreed.
That's how you ended up staying late most nights so you could give her a foot massage as she finished up her work for the day. That's also how you ended up sucking on her toes while she played with her pussy. It turned out that she was a great deal kinkier than anyone would have imagined at first sight.
You came to love those late nights. You'd rush to her office, get on your knees under her desk, and rub her feet dutifully as she finished the last emails of the day. Then she'd let you suck on her toes while she pulled her skirt up around her waist and masturbated. You were permitted to stare at her pussy, but you were never permitted to touch it or yourself. You could jerk off thinking about her when you got home, but you were never to sully her pleasure by pursuing your desires in her presence.
Then, a few months into your arrangement, she wasn't in her office when you arrived. She'd left a note, though, telling you to get under her desk and wait until she returned. You felt foolish doing so, and yet you couldn't resist the allure of doing as you were told.
You waited for half an hour. You heard her door open. You saw her legs as she approached her desk. She pulled her chair back, sat down, and beckoned you to crawl out.
She informed you that she'd seduced her boss, that he'd just fucked her tight young pussy, that he'd be fucking her on a regular basis going forward and that she'd be using his lack of self control - he's not supposed to fuck an underling, after all - to forward her career at a more rapid pace than any of her coworkers.
Then she pulled her skirt up around her waist, inched her chair forward, and guided your mouth between her legs. She informed you that her boss had cum inside her and you recoiled. She grabbed a handful of your hair and told you to be a good little bitch and clean his load out of her or you'd be banished from serving her in any way. Then she told you that she planned on taking you with her as she rode her way to the top of the company, but only if you could be a good bitch for her, if you could do as you were told without argument.
You folded. You cleaned her pussy. You swallowed another man's cum. You gave her an orgasm while doing so, and she showed her appreciation by calling you a 'good boy' when you were finished. She informed you that you'd likely be cleaning three to four loads a week from her pussy, maybe more. She also told you that you'd be expected to remain sexually flexible throughout your service to her, that she might find other ways to use you to her advantage as time went by.
You jerked off twice that night and both orgasms were incredible. It turns you that you were made for service, that you were always destined to be a good bitch for a powerful woman like her.
