That Wasn't Novocain...

Samantha lay back in the dentist's chair, her heart pounding in her chest. She hated the dentist, but the Novocain had dulled her senses and she was almost relaxed. Almost.

Dr. Sinclair leaned over her, his large, dark eyes flashing. "Are you comfortable, Samantha?" he asked, his voice deep and soothing.

She nodded, trying to keep her eyes open, but the drugs were making her sleepy. "Y-yes," she slurred.

Suddenly, she felt a hand on her thigh, sliding up her skirt, and she jerked awake. "W-what are you doing?!" she gasped.

Dr. Sinclair chuckled, his hand still resting on her thigh. "Relax, Samantha. I just want to make sure you're feeling good." His fingers inched closer to the edge of her panties and she squirmed.

"I-I don't think this is appropriate," she stammered, trying to push his hand away.

He leaned in close, his breath hot on her ear. "Come on, sweetheart. Don't be such a prude."

Samantha's head was spinning from the gas and she couldn't think straight. She felt herself getting wet as Dr. Sinclair's fingers brushed against her clit.

Samantha moaned as Dr. Sinclair continued to tease her, his fingers expertly working her pussy. She tried to resist, but the drugs had taken over and she found herself giving in to the pleasure.

Suddenly, she felt a strange sensation in her chest and groin. It was like a warm glow spreading through her body, making her feel tingly all over. She looked down and gasped as she saw that her breasts were growing larger by the second.

"What the fuck?!" she exclaimed, looking up at Dr. Sinclair with wide eyes.

He just smirked at her, his fingers still working their magic on her clit. "Relax, Samantha," he said. "You're going to love this."

And he was right. As Samantha's breasts grew bigger and rounder, so did her libido. She felt an insatiable hunger for sex coursing through her veins and couldn't help but moan loudly as Dr. Sinclair slipped two fingers inside of her.

As Dr. Sinclair continued to finger her, Samantha's nipples began to harden and ache. She couldn't resist the urge to touch them, so she reached up with one hand and began pinching and pulling at them.

"Oh god," she moaned, feeling the pleasure intensify as she played with her nipples. "Fuck me harder, doctor."

Dr. Sinclair obliged, thrusting his fingers in and out of her faster and harder. Samantha could feel herself getting closer to orgasm with each passing moment.

But then something strange happened. As she twisted and pulled on her nipples, they began to grow longer and thicker in her fingers until they were almost painful to touch.

Samantha hesitated for a moment, unsure of what was happening to her body. But then the pleasure overtook her again and she resumed playing with herself even more vigorously than before.

Dr. Sinclair leaned back in his chair, watching with a smirk as Samantha's body continued to transform under his touch. "That's it, Samantha," he said, his voice low and commanding. "Touch yourself harder."

Samantha hesitated for a moment, unsure of whether she should obey him or not. But then the pleasure overtook her again and she resumed playing with herself even more vigorously than before.

As she did, Dr. Sinclair began to give her more commands, each one making her body transform further. "Pinch your nipples," he said. "Harder."

Samantha obeyed without hesitation, feeling a jolt of pain shoot through her chest as she did so.

"Good girl," Dr. Sinclair said with a grin.

Samantha felt a rush of embarrassment at being called that but couldn't deny the pleasure it gave her to hear it.

"Spread your legs wider," he commanded next.

Samantha hesitated for just a moment before doing as he asked.

"That's better," Dr. Sinclair said approvingly as he slipped another finger inside of her.

Samantha moaned loudly at the added pressure, feeling herself getting closer and closer to orgasm with each passing second.

Dr. Sinclair's commands were all that mattered now, and Samantha was powerless to resist them. She felt the familiar wave of pleasure building inside her and knew she was about to cum.

"Cum for me, Samantha," Dr. Sinclair growled in her ear.

Samantha screamed as she came harder than she ever had before. As she did, she felt something strange happening to her body - it was like all of her resistance and intelligence were squirting out of her pussy along with her orgasm, leaving behind a submissive bimbo slave.

She looked up at Dr. Sinclair with wide eyes, feeling dazed and confused by what had just happened to her.

Dr. Sinclair grinned down at Samantha, his cock hard and ready for action. "Good girl," he said, patting her head like she was a pet.

Samantha felt a twinge of disgust at the condescending gesture but couldn't deny the pleasure she felt at being praised by him.

"Get on your knees," Dr. Sinclair commanded, his voice low and commanding.

Samantha hesitated for just a moment before reluctantly doing as he asked. She didn't want to be seen as submissive or weak, but something about Dr. Sinclair's dominance over her made her feel powerless to resist.

Dr. Sinclair grabbed her by the hair and pulled her face towards his cock. "Suck it," he growled.

Samantha opened her mouth obediently and took him inside, feeling him fill up every inch of her mouth.

"That's it," Dr. Sinclair moaned as she began to bob up and down on his shaft. "Take it all."

Samantha tried to ignore the taste and smell of him as she sucked harder, feeling herself getting wetter with each passing moment.

But then something strange happened - as she sucked harder and harder, Dr. Sinclair's cock began to grow longer and thicker in her mouth until it was almost too big for her to handle.

She gagged slightly, trying not to choke on him as he thrust deeper into her throat.

"Deepthroat me," he commanded next.

Samantha hesitated for just a moment before doing as he asked once again, feeling herself becoming more submissive with each passing second under his control.

Samantha's mind was racing as she continued to suck him, feeling both aroused and disgusted by the taste of him in her mouth. But then something strange happened - as she sucked harder and harder, Dr. Sinclair moaned louder and louder until he came deep down into her throat.

Samantha swallowed gratefully, feeling a mix of relief and satisfaction at having pleased him. She looked up at him with wide eyes, still unsure of what had just happened but unable to deny the pleasure it had given her.

Dr. Sinclair looked down at her with a smirk on his face. "That was good work, Samantha," he said approvingly. "You're really getting the hang of this."

Samantha felt a sense of pride at his praise but couldn't help feeling ashamed at how easily she had given in to his control.

"I'm going to take a quick step outside while you clean yourself up," Dr. Sinclair said gruffly as he stood up from his chair. "If you need anything, just call out to my secretary's desk."
