"Please, treat me unfairly!" Those had been Anita's words when she'd become part of her Mistress' harem.
Since that fateful day she'd gotten exactly what she'd asked for and she'd loved every second of it. She loved it when another slave made a mistake and she got punished instead, under some flimsy pretense like "You should've prevented that" or "Obviously you haven't been good enough of an example to your slave sister". She loved how her Mistress always turned a blind eye when the other girls decided to torment her (and in turn the others loved Anita for this opportunity to let off some steam and live out their own sadistic fantasies).
Most of all, though, she loved that she wasn't rewarded with orgasms like the other slaves. Instead her (rare) rewards came in the form of challenges where she could earn an orgasm if she succeeded. Or an especially cruel punishment if she failed, because "she'd proven that she wasn't worthy of the reward".
Sometimes Anita bested these challenges. Usually, though, she didn't. As a result, she was one of the horniest girls in the harem. This created a feedback loop, where due to her arousal she was more likely to provoke her Mistress and the other slaves into giving her a hard time, which lead to more punishments and less rewards, which lead to even less orgasms and the cycle continued.
Still, she'd managed to be a good girl for long enough to earn herself a reward once more. Anita knelt to her Mistress' feet, waiting to hear what challenge she'd have to endure this time. Her pussy was throbbing already and not just from the past two weeks where Mistress hadn't allowed her any release. She'd also spent a good part of the previous night pinned down by a bunch of the other slaves, while Clara had tortured her with a clit pump she'd smuggled into the sleeping quarters.
Clara, that fiery blond with the stunning slim body and irresistible lips, was usually the ringleader. Anita had heard that Clara had been close to quitting her place in the harem, because she wasn't satisfied with a strictly submissive lifestyle anymore. Luckily, around that time Anita had joined, to everyone's profit. Clara could finally live out her mean streak while Anita got someone playing the role of the big bad bully for her.
This same Clara was now kneeling beside Anita. Their Mistress had demanded her to be part of Anita's reward to make up for the previous night. Anita knew exactly, if it'd been her who'd been caught with a stolen sex toy, she wouldn't have gotten away so easily. Her punishment would've been drawn out and painful. Just thinking about this injustice got the juices flowing from her aching pussy. Two weeks was a lot, even for her. She really needed to secure herself that orgasm.
"We'll keep this simple." Mistress' voice cut through the silence. She pointed at a pile of pillows on the floor. "Clara, you'll put your head there and Anita, you'll squat over her. Clara will lick you for as long as you stay in position. If you move away before you've come, you clearly didn't want that orgasm all that much. In which case I'm sure you wouldn't mind waiting another month for your next chance."
Anita swallowed. She'd been denied for a month before, but at the time she'd become such a horny mess that the memories were a pink haze. And back then she hadn't started the month with a dripping, aching pussy and two weeks of denial already behind her.
"Don't worry, I'll give my best so that doesn't happen." Clara's voice was saccharine. Her eyes shone in a way that Anita knew all too well. Clara wasn't going to make it easy for her.
"I'm sure you will," Mistress said. "Because if you can't make her come in time, it shows that you don't have the oral skills I require of my slaves. In that case, since you obviously need more training, you'll be the harem's pussy girl for the next month. You'll spend your time licking all my other slaves until I decide that you're good enough."
Clara looked completely taken aback for a couple seconds. When she turned back to Anita, her eyes were still shining, but she didn't even try to sound sweet anymore. "If you humiliate me like this, I'll so make you pay for it."
Anita just nodded. As expected, her Mistress acted like she hadn't heard Clara's obvious threat. If Anita failed, no one would rescue her when Clara decided to make her life hell. In what little time Clara had left where she wasn't forced to eat pussy, of course. The thought of having a thoroughly humiliated Clara pick on her even harder was almost alluring enough to fail on purpose. Almost. As much Anita she loved being the harem's bottom bitch, she'd go crazy if she couldn't relieve her arousal from time to time and another month was fucking forever.
"Get in position!"
With a last warning glare Clara lay down and rested her head on the pillows. For a second the corners of her mouth twitched to a grin, though, betraying her act. Anita was sure that Clara would have fun, no matter how this challenge ended. Which was kinda scary. It meant that Clara might choose not to try very hard, just to spite her.
