"I'm not leaving until you give me a chance too! I'll show you that I'm a better cocksucker than that slut Amy!" Sam insisted as her pussy moistened at the idea, sending her own imperious pheromones out to mix with Amy's enticing scent throughout the room. Sam stomped over to the CFO, her slutty mouth already salivating in anticipation as her intimidated prey rushed to undo his belt.
"Sam you bitch! Go find your own dick!" Amy yelled angrily during the few seconds she could bear to spend without that tasty cock between her lips, but Sam completely ignored her and began working the CFO's shaft and balls with a vengeance. Even if she'd wanted to leave, however, Sam was powerless to resist her own compulsion for dick, which had been the cost of the powerful, irresistible bimbo body the potion had blessed her with.
Even over the sound of her own slurping as she continued to massage the president's cock with her tongue, Amy could hear Sam across the table teasing the CFO as she alternated thinly veiled threats with stimulating him with her lips and tongue.
"Your cock is so hard! I bet it really wants to cum, doesn't it? It'd be a shame if you, like, didn't hire me and I had to stop. You do want to hire me so I can keep going, right?" she wheedled as she gave him one final brief lick and looked up into his eyes hungrily.
Surely he knows that Sammy won't be able to stop until she gets his yummy cum, Amy thought to herself. She gathered enough willpower to briefly look up from her own irresistible cum dispenser, and was rewarded with the sight of Sam's delicate fingers continuing to mechanically stroke the CFO's cock even as she threatened to stop.
All too predictably, however, Amy heard the CFO nonetheless responding, "Oh God yes! Of course! Anything you want! Just don't stop!" as the sensation of her thumb rubbing up and down his sensitive frenulum became more than he could handle. His overstimulated cock began to shoot its load all over her statuesque features framed by her silky black hair, and her seductive green eyes glimmered with excitement and satisfaction as the first spurts of his semen painted creamy trails across her face. As his ejaculation began to tail off and her compulsion to direct all of her attention to the cock jerking in her hands lessened, Sam glanced back across the table at Amy with a cum-coated smirk of victory.
Undeterred, Amy looked up at the company president she was fellating, a captivating smile on her own angelic features, and said "I, like, just want to do a good job, sir. I hope you're enjoying yourself," before sensuously sliding her tongue up the underside of his dick. Then, throwing caution, modesty, and professionalism to the wind, recognizing that she would need to go all out to beat Sam, Amy finally gave in to her pussy's demands to be filled. She stood up, turned around, pulled her skirt aside, and slowly slid his slick cock deep into her silky, luxurious depths.
As wave after wave of pleasure rewarded her for using her body the way it was designed, Amy admitted that she loved having a dick in her pussy too, possibly even more than she loved having one in her mouth. All the while, her pussy did what came naturally, enthusiastically pulling and gripping at the skin of the president's sensitive cock, coaxing him back inside when he withdrew and then tightly squeezing him in her slick, inviting embrace as he reflexively slid himself back into her, forcing him ever closer to his limit as her pussy persuasively encouraged him to lose control inside of her, to give in and let her relieve him of all of that cum uncomfortably filling his balls and beginning to pulse urgently at the base of his cock.
Recognizing his imminent orgasm, Amy pulled off completely, and then slowly pressed his cock deep into her stimulating pussy one last time, finally triggering his involuntary response, and he moaned as his body began to release itself into her heavenly embrace. His eyes rolled back into his head as the most pleasurable sensation he had ever felt seemed to go on and on as her tight grip continued to milk him into oblivion, and he was forced to fully empty himself into this slutty bimbo, specifically engineered to be the perfect receptacle for his cum.
"Thank you, ladies. You've both capable of very, eh-hem, persuasive performances. Now we'll need some time to deliberate privately, and then Phil will let you know our decision."
It came as no surprise to Amy when Phil summoned her into his office a half hour later. Once the CFO had been freed from Sam's imperious influence, the choice had been clear. Sam, of course, was livid when Phil called Amy back, but there was nothing she could do, and the look of furious impotence on her face at having been outperformed made all of Amy's tribulations of the past week more than worth it.
As Amy walked into Phil's office to accept her promotion, she was again impressed with just how cute and manly he was as her slutty cravings were rekindled at once more. Phil was talking though, so Amy tried to listen and not be distracted with thoughts of what they should obviously be doing instead.
"They were very impressed by your performance, and are prepared to offer you the position. It was a tough choice between you and Sam, but while Sam was self-confident, knew exactly what she wanted, and was practically impossible to say no to, your clear eagerness to please won the day."
Amy flushed at the praise, and at her ultimate victory over Sam. "You won't regret this sir!" she gushed, licking her thick lips suggestively, and encouraging her pussy as it began to pulse anew. She walked around his desk, embracing her urge to show her boobs along the way as she unbuttoned her blouse and allowed her massive tits to swing freely in his face for a few seconds before bending down in front of him.
"Amy, while I appreciate your initiative, I'm not sure I'm-" he began, but then her scent began to have its effect on him once more, and he realized that he did want one final round with the slut after all.
"Shhh..." she whispered as she pulled his chair out from behind his desk and sank between his legs. This time she had something slightly different in mind, and after pleasantly lubricating his cock with her soft mouth and tongue as he moaned, she wrapped her giant tits around his short dick and began squeezing and pulling up and down, enveloping him in the sight and sensation of her soft, jiggly breasts. When she sensed him ready to cum, she pulled her tits apart enough to reach him with her mouth, and gently closed her puffy lips around his cockhead as she continued to stroke his shaft with her fist, shivering with pleasure when she felt him reflexively pumping her mouth full for the second time that morning.
Afterward, Amy went back to her desk licking her lips clean, once again filled with satisfaction for filling her bimbofied body with the yummy cum that it craved. She was so happy - she'd gotten everything she had ever wanted. Success, a promotion, revenge on Val and Sam, and all the throbbing cock she could take. I'm a woman with needs, after all, she giggled to herself, and then watched Val heading back to her desk after another session in the janitor's closet, closely followed by a delicious-looking young man with a glazed smile on his face.
She watched Val stop briefly by Sam's desk and grab a familiar bottle of hand sanitizer to clean the cum off her fingers, and she watched as Sam freaked out and tried in vain to prevent Val from squirting the liquid into her hand. Val did so nonetheless, froze briefly, and then began excitedly rubbing the hand sanitizer into the creamy tops of her boobs as they pressed out above her tight tube top, before pulling her top down entirely and massaging the tingly liquid into her large, naked breasts, twisting her thick nipples as her eyes widened and her pupils dilated in pleasure.
Sam slumped down into her chair, completely defeated, absent-mindedly pulling apart her blouse to squeeze the needy bimbo tits that Amy had inflicted upon her as Val calmly succumbed to the effects of the potion once again. Sam hadn't even wanted big, sexy bimbo tits before Amy had tricked her into dosing herself with the potion, and now that she had them she couldn't help but love the way they hung heavily from her chest, the way they demanded her attention and rewarded her with pleasure for indulging them, and the way they caught men's eyes and were the first step in making them want to fuck her. The anticipation of getting Amy back, of watching Amy helplessly turning into even more of a cock-hungry bimbo slut was all that had kept Sam from dosing herself again, but now that Val had stolen her revenge, Sam regretted not having just dosed herself so she could be the one experiencing the mind-numbing pleasure of swelling into an even bigger bimbo instead.
