Primum Non Nocere (closed)

[DanFS]

Dan couldn't hide his pleasure at Lisa's willingness to stay in the room to 'rest'.
As Dan re-dressed, he left her lying upon the exam table. He reached into a drawer, and withdrew four leather cuffs with chains attached, which he started to attach to each of her wrists and ankles.
Her pale skin, in stark contrast to the black leather of the cuffs and chrome chains, almost glowed. She looked magnificent.
Dan then held up a ball-gag.
"Do you know what this is?" He asked

 

[Mephistophelily]

She watched with curious interest as the doctor redressed, laying on the table and letting her finger run against her lower lip nervously. Her mind refused to stop... Thinking and imagining, chiding her and reveling at the same time.

This is bad.
No it's not. This was.... Unbelievable.
It still is.
What the hell am I doing?
Am I seriously doing this?!
...I can't go. I can't. I want to know more. I want to do more. This is-is....

Lisa sat up slightly as he reached into one of the drawers on the little desk, gasping softly as he withdrew the cuffs. Her thighs pressed together with the sight of them, her lips tightening once more as he placed them on her wrists.

She was shaking. Not from fear.

I want this. I- I really want this... A full realization hit her then, feeling the slightly heavy leather and chrome clutching her ankles.

She glanced over as he returned to the drawer, a little red ball attached to a strip of leather dangling from his fingers.

"Do you know what this is?"

Lisa stared at it for a moment, slowly nodding. "Y-yes, Doctor. It's... It's a gag...." She looked a his face for a moment, then back to it. She swallowed again, her knees shifting on the table. "Please.... Please, Doctor. I... I want that."

 

[DanFS]

As Dan heard Lisa say she wanted to be gagged, his heart soared. Here she was, the one he had been seeking.
THE ONE!

"I want it too, little one." He replied.
He happily asked her open her mouth so he could insert the ball of the gag, and noticed his hand was shaking.

When she raised her head so he could buckle the black leather behind her hair he smiled a wide beaming smile. She was a natural!

Once he was satisfied it was secure, he gently stroked her - from her hairline, down to her toes. Not to tickle her, but to revere her beauty, and to signify how precious she was to him.

He patted her thigh, and said "Good girl!", then opened a nearby drawer under the counter and set what looked like a baby monitor upon the top of the counter, then stood a small bell on a stand next to it.
He tied a length of string to the bell and ran it all the way to Lisa's hand and tied it securely to her thumb.

"IF you need me, I'll have the receiver to that monitor on my desk. Pull the string to ring the bell. Call it a test. I want to keep you safe, but see if you can last without ring it."

He looked her in the eye and smiled again, before using surgical tape to attach a bullt vibrator between her pussy lips, nestling against her clit.

He reached into his pocket and held up the remote, and pressed the button, to give her a quick buzz, before leaving her upon the table, and going into his Office to write his notes.

He had much planned for her, and not all of it would be pleasant, but he was sure they would both enjoy the future.

 

[Mephistophelily]

Lisa was trying hard to not shake anymore as the Doctor leaned over her, the light words murmured to open her mouth and the ball slipping between her lips. It was bigger than she expected, a meek whimper leaving her as she raised her head, closing her eyes as she felt his hands against the back of her head.

She swallowed hard, laying back down and looking up at him as he smiled. She tried to give one in return- but found it rather hard to do that. As his hand passed against her, she shivered, her fingers and toes all managing to curl slightly as she cooed behind the ball. Her cheeks flushed a bit as he praised her, her head raising up a bit again as he pawed through the drawers once more. What was that thing?

He explained what it was for, and how she could reach him if she grew scared.
She nodded, though at the moment.... she really didn't think she'd be doing that. Sure, her heart was pounding insanely, but....

"Hmnnfn-nn?" Her hands tightened up as she tried to peer, realizing that he had tucked something else into his palm as he leaned over her once again, the sound of tape ripping coming to her ears before feeling something pressed against her sex. She swayed her hips slightly with the new curious thing, peeking up to see the little remote held in his fingertips. Before she could really equate the two's relationship, he showed her- a sudden jolt from the toy he'd left, Lisa squealing into the gag as her back arched up.

It stopped.
She glanced at him again, seeing the smile still there as he left the room.

Her head lolled ot the side on the table, closing her eyes as she gave a long moan against the gag, that shiver returning. That thing could control it from way back in his office? Or was that just to show th-

*Bzzzzzz*

"HnnnNNNNnnnn-!"
Lisa's body writhed on the stand, her pussy throbbing against the vibe as he proved exactly what she had questioned. Oh god, she couldn't even see him push it- there was no real warning- just... just it happening...

She panted as it came to a stop, shaking on the table as she tried to relax. But now the idea of it, him just randomly pushing as he pleased... Could he even see her? He said it was the monitor to worry on. Ring the bell if she were frightened.

She glanced at the string. It was still hanging loosely.
Lisa wouldn't pull it.

 

[DanFS]

Dan smiled as he sat in his office chair and booted up his computer.
He thought of Lisa, tethered to the exam table vulnerable to his every whim.
As he started to type her notes that he marvelled at just how responsive she was. She had completely transformed from a shy teenage girl to a full blown sexual woman. The change was quite remarkable.

Within her notes he documented her drastic responses to the various stimuli and also that he was recommending her to attend a research programme at a nearby institute of which he was a member.

Dan was still surprised at the eagerness with which Lisa agreed to be cuffed to the exam bench and even more so that she knew what a ball gag was and happily accepted it within her mouth.

He decided to test her devotion. He once again took the remote from his pocket and flicked the button he knew that in the other room Lisa’s pussy that would be getting a jolt from the vibrator. He reached across his desk and flicked a switch and instantly the picture upon his computer screen showed a little window in the corner with an image of the exam room clearly shown upon it.

He pushed the button on the remote again but this time held it down for a couple of seconds and was rewarded with the sight of her writhing upon the table top struggling against her bonds. He now cursed himself, for not having the foresight to install sound capability with the monitor. He was quite sure that the noises coming from Lisa would be quite delicious.

He entertained the notion of releasing his stiffening cock and stroking it whilst watching her on the screen, but she had been so responsive it seemed a waste. He watched way with her for a minute or two more once he had completed her notes and then return next door to play with her once again.

For now, he settled for resting his hand upon his cock through his trousers and watching the screen as he pressed the button on the remote at random intervals and watched Lisa’s reactions.

 

[DanFS]

.....

 

[Mephistophelily]

Lisa stared up at the ceiling for a bit, twisting her legs at intervals... That anticipation of his sudden decision to hit that button again driving her mad. He had only done it twice so far, but she already felt her wetness against her thighs. She whined into the ball, rolling her hips upward and trying to readjust. She.... Wanted more... She knew he was busy, but to not have it was nearly maddening-

*bzzzzzzzz*

She squealed out once more, the sound of the toy and the chains of her binds echoing in the room as she thrashed at first, the buzz seeming to last even longer this time. Lisa struggled to keep her breath as it continued its attack, her eyes closed tightly as she moaned.

It finally stopped.
She dropped her hips back against the table, a heavy groan buried against the ball. He gave her just enough.... Just enough to want more, push her so far.....and then left her there. Part of her was ready to cry in frustration, another- absolutely loving it. The tease, the control, the lack of it she had now. It was all in his hands, those strong amazing hands that-

*bzzzzz*
"GnnnnnDNNNNNmmmm!" Her ache was beyond just need now. It was absolute desire, an angry demand that tore through her.
The bell...
No. No! Can't-
But he'll come back...
It's for absolute emergency...
... Isn't this one?!

She looked around again, the whimper now staying in her throat as a soft continuous noise. Come back, please come back, oh god, please...

She spotted it then, the glimmer up on the stand. A camera lens. A webcam- he was watching her, wasn't he? She stared at it, howling into the gag and pulling on her binds. Come back, please... I don't want to ring it, I just want... I want you here...

 

[DanFS]

After a few minutes Dan decided her had tormented her enough.
He could plainly see her desire in her eyes through the camera, and besides, he had gotten hard again watching her, as he flicked the button at random intervals, to test her responses.

He had prepared the letter to her Doctor, with a copy to her parents, to explain the course of research at the local Research Institute, where he had an ongoing suite of rooms, in which he carried out tests on his patients who required 'further investigation'.

Lisa certainly fell ito this category! The letter explained that there was nothing to worry about, but some slightly higher than usual readings on the initial tests needed looking into. As a token of gratitude, in the name of furthering medical science, he also offered Lisa a 'bounty' of $200, for the time she donated to the research, since it wasn't to resolve a serious medical condition.

He placed the letter to her parents in an envelope, and adjusting himself, so he could walk more comfortably, he opened the adjoining door and re-entered the examining room.

Lisa looked divine, tethered to the table as she was, and Dan stopped to take in the vision before him. A he approached her, he could see the thin sheen of sweat covering her, and the scent of her musk filled the air.

He reached down and released the buckle on the ball gag, pulling it free, to allow her to exercise her jaw msucles and get used to being able to breathe through her mouth once more.

"Hello Lisa. Did you enjoy yourself whilst I was away?"

He placed the letter upon the chair nearby, and added:
"What would you like to do now?"

Although it was a loaded question, he wanted to her her say it.

 

[Mephistophelily]

"Nn?" Lisa heard the door open, but her current positioning made it hard to see exactly who had stepped in. Doc? Or his secretary? Oh, god- another patient wandering into the wrong room?!

His voice calmed her slightly, though to hear it's deep purr sent another chill through her. He seemed to be studying her as he came to her, the thin smirk resting on his face. She could feel her cheeks reddening even more, her legs trying to kick and twist in their binds.

The gag was peeled from her lips, Lisa's tongue helping to push it free, her eyes set on the line of drool that followed the ball and widening. Stretching her lips a bit, flexing and puckering, she glanced over at him, a purr of her own coming out as he inquired on her being alone.

"Muh- Uh-huh..." She was still having trouble finding her voice, peering after him as he headed to the chair. "It was... It was a little... lonely."

"What would you like to do now?"

She swallowed hard, staring at him as he turned back around. That smirk was still there. Her eyes trailed down his chest, trying to get away from that smile- only to fall upon his tented pants. Lisa's breath locked in her throat, the need he had caused from his love of that button suddenly more than she could take.

"I- I want it again, Doctor. Please... Please, make it stop... It's driving me crazy, I just want to- to... Doctor, please, I want more..."

 

[DanFS]

Dan was amazed that she could be so wanton, but also glad, as he had a monster erection he needed help with!
When Lisa said “Doctor, please, I want more...", Dan was only too happy to oblige.
With little ceremony, he unzipped and slid his length into her, in one go. She was so wet and aroused, he could clearly see her clit peeking out, and as he started to thrust slowly in and out of her wet pussy, he reached down to tease it and relished her responses.
Her gasps and moans grew louder, as they both approached their orgasms, with Dan’s thrusts becoming more fierce and faster with each passing moment.

His moans grew in their intensity too. She was still so tight and her need reflected his own. As her pounded into her, he watched her taut breasts shaking, and her moans and groans being punctuated with each cycle of thrust & withdrawal.

It was only a matter of time before he reached the point of no return, and leaned into her to gently bite a nipple as he shot pulse after pulse of his seed into her waiting cunt.

As he gradually recovered from his orgasm, he was pleased to see that she also appeared to have cum again, even iof the cries she made, hadn't been obvious enough!
As they re-dressed and walked back through to his Office, Dan handed Lisa the envelope containing the letter to her parents.
“Make sure they get this and you have their signature, to permit you to join the research programme. I look forward to seeing you next week. Please call me to let me know what day & time you can get to the Institute. I can work my week around you, but we need to allow a full day for the investigations, OK?”

He smiled and watched her go, and as she shut the door behind her he breathed a huge sigh.
Life had just got very interesting!

 

[Mephistophelily]

"D-Doctor-!" Lisa gasped out as he buried into her, her whimpers quickly turning to loud howls of bliss, her hips rocking down against him as he fucked her. She had never felt this way before. She'd had sex, sure- but not like this. What he had shown her was far, far different. It made her feel... amazing. Unimaginable. She had no idea that she could even feel this way. So much for being afraid of going to her appointment. The exam itself had certainly not been what she had thought- and what happened after.... Teased, tied down, and him guiding all this out of her...

"Hnah- hah- Ohhh, god, Doc, I-I'm gonna... Please, please, more, I'm... OHHH-!" Lisa almost wished he had given her the gag back. She'd never been this vocal before. At least the tethers he'd left attached to her kept her from thrashing in her bliss, her back arching up from the table as she screamed out. She hoped the receptionist didn't hear.
No, actually.. she didn't really care....

Gasping for breath, she settled back against the table, a panting sweating mess as he reached down and undid her clasps. She simply watched, a contented little purr and hum leaving her as she moved her hands back to rest on her tummy, laying there a moment before slipping off the table. Wobbly legs, for certain, she noted as she redressed.

Flush and smirking sheepishly, she followed he back to his main office, nodding as he gave her the letter and instructions on what it was for. "Y-Yes, Doctor. Th... thank you."

Heading back out, her purse slung lazily over her shoulder, she could only shake her head quickly as the receptionist called out to her on scheduling a new appointment. She was more worried on getting home. Showing this to her mom. As a student, she was still under their insurance, so anything medical was going to need her okay. A study could be... interesting.

"So there's something wrong with you?," her mom asked worriedly as Lisa told her of it in the car. "They found something? Oh, honey, what was it?"

"No. Nothing like that, Mom. Doctor Ford just found something curious about me. He didn't say it was anything bad or life threatening. Just a- what was it? Case study. Yeah, I think that was it. A research project. I mean, he's giving me $200 to participate. You did say I needed to cover my own books this semester, so if I can be helpful in his research project, and get the cash- two birds one stone, right?"

"I should call him."

"Mom-! Really? Just... here. He sent a letter for you to sign. The whole insurance thing... Me being a student, blah blah." She handed over the note, rolling her eyes as her mother pulled over immediately to read it. "Oh, good lord, right here? Seriously?"

"Hush." Her mother skimmed the letter, frowning slightly as she made her way down, then gave a hard sigh. "Well, he does say it's not a serious condition..."

"Yeeeep. I said that too..."

"Alright, I'll sign off on it. What exactly did he say was curious about you?"

"Just... some... readings? You seriously think I can understand Doctor Talk?" Lisa laughed as she shrugged. "I dunno, mom. He just said there was something really unique about me that the Research Institute might be interested in. I just need to call and schedule."


She called as soon as she got home. The door of her apartment had barely latched before she was on her cell phone, dialing earnestly the number on his card. "My name's Lisa Hawthorne...? I'm... I'm a patient of Doctor Ford, Dan Ford? He... gave me the Institute's number to set up a time for a ses- Oh. Oh? Um... Sure, yes. Tuesday at 10 am? Alright.... Yes, thank you."

A rather short, blunt call. No real explanation, either. Hm.
She called his office line, reaching the answering service instead. She left a message, trying to hide the shake and nervousness in her voice before hanging up.
It was going to be a long weekend...


---------------

Tuesday morning, 9 am.
She awoke with a faint smile as her alarm went off, reaching over to hit it and sighing. Classes the other day were impossible. Her thoughts drifted to what would happen today... What kind of tests did he have in mind? More like that appointment? She had ended up shifting and squirming her way through the day, barely focusing at all...

She was up, into the shower quickly, cleaning up for the day's events. A full day, he had told her. What exactly was going to happen? She shivered as she washed, recalling the taste of the gag, the cool touch of the binds- More like that? More of... of him?

A little gray skirt, a white tee, a black vest over it... white knee highs, black clogs. Clothing easily removed if need be, but nice enough for her cab ride there. Her mom had offered to take her, but she had refused. "I don't know how long I'll be. I don't want to hold up your day. Don't worry on me! I'll call you when I can, okay?" Her hair back in a loose ponytail, and she was out to wait for her cab.


Her eyes widened as the car came to the front of the Institute. He was in there, wasn't he? Waiting for her. She smiled to the driver as she slipped him his money, climbing out nervously and starting up to the door. Another receptionist, another warm smile. "Well, hello there. And who are we here to see today?"

"I'm Lisa Hawthorne. I- um... Doctor... Doctor Dan Ford... was- is supposed to meet with me for... a study?" Her voice had suddenly decided to leave.

"Ohhh, yes." Her smile grew, as if she knew something... "Have a seat, dear. I'll let him know you're here."

 

[DanFS]

Dan was reviewing his case notes for Lisa Hawthorne when his intercom buzzed.
It was Suzie, the receptionist, letting him know Lisa had arrived, as planned.
He had deliberately cleared his diary of everything else he would have had for today, when Lisa had confirmed her appointment. He wanted to make sure that nothing was going to interrupt his session with her!

Dan replied to the buzzer and flicked the switch to talk.
“Suzie – please escort Miss Hawthorne down to my Consulting Room, whenever she is ready. Thank you.”

Suzie was a pretty blonde, with her hair in a pixie cut & mid-height at five foot eight, and a firm size ten figure, with 36B breasts and slim hips and a firm tight ass, clad in black semi-formal trousers which clung to her curves alluringly. She wore a crisp white blouse on her top half.
As Lisa could clearly hear the request over the speaker, which sat on Suzie’s desk, it was hardly a surprise when Suzie stood and walked over to Lisa.
“Miss Hawthorne, if you’d like to follow me, please, I’ll take you down.”
She turned on her heel and started to walk away, toward the double doors marked “Authorised Personnel Only”.
As she approached, she held out an access/ID card next to a sensor, which operated the doors with a muted buzz. Suzie looked back over her shoulder, to make sure Lisa followed. She led her down a sterile corridor which ended in another set of double doors, her heels clicking upon the tiled floor.
She swiped her card over another sensor which opened the doors with another buzzing sound.
As she pushed the door open, and stepped inside, she indicated to Lisa to walk in first and she was then presented to Dan.
Sitting behind his desk, tapping at his computer, he looked up and smiled, as the women walked in.
“Lisa – good to see you again!”
He nodded to Suzie, and said “Thank you, Suzie. I’ll call for you again when I need you.”
She simply smiled and said “Very good, Doctor.” Before steeping back out of the room, and shutting the door behind her.
Dan stood and walked around his desk, holding out his hand for Lisa to shake.
He looked into her eyes for any clue that she was nervous or frightened and was reassured to see a confident face smiling back at him.

He walked across to another door, which he opened and ushered Lisa through into another exam room. It was set out much like the other one at the Clinic, with a few other additions, including a St. Andrew’s Cross, and a Bondage Bench.

“Right, Lisa. Let’s get started.” He said. “Please strip for me.”

His language was subtly different to last time. This was more of a command than a request. He expected Lisa to do so, just the same, and wasn’t really paying attention to her, as he opened a cupboard and took out a syringe, which he jabbed the needle into a bottle of something which he sucked an amount into the barrel.
He flicked the barrel to get rid of the bubbles within before laying it down on the side of the counter, and turning back to her, to see her slowly removing her clothes.

“Don’t worry – we have a lot to do. We’ll repeat some of what we did last week, and carry on your treatment a little further, so I can monitor your responses, as promised. I’m sure you’ll enjoy it! I just have to give you this shot, which will enhance some of your responses to make them easier to measure. This drug will heighten some sensations, and is predictable, so we can calculate the base responses.”

He smiled to reassure her, before picking up the syringe and indicating for her to sit on the chair beside her.
“Take a seat and I’ll give you this, then we can continue.”

He gently administered the injection, warning her it would sting a little and that after a couple of minutes, Lisa might feel a little strange, but it won’t be unpleasant. She might even feel a little aroused, Dan warned.
He opened a drawer and took out a box, and placed it on a trolley next to the chair she sat on.
Dan gestured for her to open it.
Inside was a black satin corset, with a black silk thong, and a pair of sheer black hold-up stockings, and a pair of black court shoes, with five inch heels.
When she looked up at him in confusion (as surely this isn’t necessary for a medical exam, is it?) he said to her:
“Oh, come now, Lisa. Don’t pretend you didn’t know what today would entail. You have already accepted that you are my slut.”

After pausing for effect, he continued.
“I want to see how far you can go, so we can map your responses. Your arousal at your last visit was over and above the normal response I would expect for one so young, and I want to find out why. You will enjoy most of what we do, and besides, you are being paid for this!”

He gestured again for her to don the garments, which although probably unusual to her as attire, were finely made nonetheless.

 

[Mephistophelily]

Lisa nodded as the other woman led her to the doctor's room, glancing around curiously. This didn't seem so bad. What kind of tests did he have in mind here? It reminded her a lot of his other office, really. She smiled at him as he offered out his hand, shaking it before he led her to another little door. Oh, so that was it. A different exam room.

She paused as she saw what this new room held. What was that big x looking thing? And that bench- What kind of exam room was this? She glanced back at him curiously, her eyes widening slightly as he requested her clothing off. "Um. Right." She smiled a little, setting her purse on one of the little stands and starting to take off her skirt. Her gaze fell on the odd x once again, causing her a slight delay in the full removal of the rest of her clothing. As she took off her bra, she peeked back at him once again- noticing the needle in his hand. She drew a sharp breath. What was that? ... A response enhancer? What did that mean? Oh, but she hated needles so much-

She bit her lip, settling into the chair he indicated and holding out her arm, closing her eyes and turning her head away as he pressed it through her skin. "Ow... oww...," She whined, shaking her fingers a bit as he finally took it back and explained further its effects.

...Aroused? Oh... Uhoh.
The box he presented to her was unexpected, Lisa peering at it curiously before he nodded for her to take it up. Taking off the lid, the contents was far from what she thought. What was this? None of those weird backwards robes? Why... Why this? "Doc..tor?" She looked up at him as she picked up the corset, confusion in her eyes.

“Oh, come now, Lisa. Don’t pretend you didn’t know what today would entail. You have already accepted that you are my slut.”

Lisa paled slightly with that, still clutching the clothing in her hands. She had wanted to explore this further, but to have it so bluntly thrown in her face like that- It was a slap, a giant one. She slowly looked back to the clothes, hearing him still talking, but the words weren't exactly registering for her at the moment. His... slut... His...

She swallowed, taking a breath and standing back up to put the clothing on. It felt strange to be wearing, but once she had the full gamete in place, she understood what he had meant before.... How easily she was becoming aroused from that shot of his. Just wearing this stuff was starting to do it for her.

"And what now, my doctor?" She asked softly, turning to look at him and resting her folded hands against the small of her back. That nervous twinge upon seeing the clothes was gone. She was genuinely curious on what he had in store... Just how much she truly could take from him.

 

[DanFS]

She looked so coquettish with her hands behind her back, unwittingly thrusting her tits further forward, in the corset for Dan’s inspection. She had a fine body, did Lisa, and he wanted to explore every inch of it, and make her experience new heights of pleasure!

As he looked her up and down, her fine legs encased in the stockings and the tiny thong concealing her pussy & ass, with the black shoes finishing the ensemble off, Dan couldn’t believe his luck – she was stunning!

She looked a little disoriented, but that’s normal with this drug. In a few moments, she would start to experience the good side of it, with her sex drive revving up quite freely, as her inhibitions receded, encouraging her to think, say & do things she might normally be too reserved to.

As her face and chest flushed with a healthy shade of pink, Dan knew the shot was taking effect.

“So, Lisa – are you ready to start?” He asked.

Not waiting for a reply, he gently rested the fingers of one hand upon her upper arm and guided her over to the bondage bench.
At one end was a lower seat, and next to it, the area where someone could either sit, or lie, which he encouraged her to sit upon.
He turned and opened a small cupboard under the counter by the wall & reached inside to retrieve a contraption.
It looked like a black box, with a flat bottom, a curved dome top, and a hole in the middle which upon closer inspection looked threaded to accept attachments of sorts.
“This is your first test today. I just need to hook up some equipment before we start.”
He placed it upon the ‘seat’ part of the bench, and reached back into the cupboard to screw a purple jelly dildo in the domed top, the phallus wasn’t that big, but it did look lifelike!

He opened a drawer and retrieved a set of nipple clamps, and some weights, and some fine chain, with clips at either end.

He placed them on the nearby trolley so she could see them, and pointed to them one-by-one, explaining their functions.
“We’ll try the clamps on your nipples at some point today, to see how you react to erotic pain. We’ll also use the chain with the clips to hold your pussy lips away from your body to give us better access to you. The weights, well, we’ll see about them!”

He didn’t give her chance to argue, just bent down and started to attach the filigree chain to her pussy lips with the clips at one end, with the other attached to the corset, near her breasts.
After he had attached the chain, he took the opportunity to slide a finger across her already moistening pussy…..

 

[Mephistophelily]

Lisa nodded as he took her arm, guiding her over to the curious bench and settling on the seat. She glanced around as he reached for one of his cabinets, curious as to what the object he was pulling out was as he gave an explanation. First test? She just nodded, her eyes widening a bit as he brought out the secondary part to the contraption. She knew what THAT was, at least-!

She swallowed quickly, staring at the object for a moment, merely glancing over as he played through more parts in a different drawer. Glancing over as he set the new pieces onto his stand, she shifted on her seat, fingers clenching into the leather padding. More curious things. She knew one of them, but the rest... They certainly looked interesting, but what were they?

Lisa nodded at the rundown of his plans for them all, staring at each piece as he gestured to them. Nipple clamps... She shivered at the idea of them, her own already starting to harden at the thought of them attached to her flesh. The chain and clips was- Oh. Ohhh. She swallowed again, shivering... a little whimper slipping in as well with the added mention on the weights. She wasn't sure what he had in mind for those, but the playful tone... That didn't help at all.

He leaned down, starting his work. As the first clip slipped against her skin, she gasped out sharply, peering down as he pulled his hand away to grab the other side. "D-Doctor...," She breathed, whimpering as the second was attached. Closing her eyes, she groaned as his touch slid against her folds, clutching that chair even more. "Ha-! Ohhh... Wh-what are these...t-tests, Doctor?"

 

[DanFS]

Dan smiled as he saw recognition dawn on her face at the sight of the jelly dildo.
When he showed her the nipple clamps, he wasn’t surprised she whimpered – it was only natural that she hadn’t encountered them before and wouldn’t know that they can confer pleasure as well as pain.

Once he had attached the clips to pull her pussy lips apart, he leant back to admire his handiwork. She did look fantastic spread open like that!

He wasn’t surprised either when she asked for clarification of the tests he was going to carry out.
“Lisa these tests will map your responses to sexual stimuli. It’s just what we went through last week, OK?”
He looked at her, for some sign of assent, or at least recall of their discussion.

As she sat there, getting used to the feel of the clips on her pussy lips, he lubed the jelly dildo atop the sybian, and used the excess upon his finger to lube her pussy entrance.
She felt warm and wet already.
Lastly he wiped his hand on a towel and got up to retrieve a set of electrodes, which he attached to her chest, just above the top of the corset, and one wrist, right over the point where the vein passes over the joint, where you would take someone’s pulse.

He connected leads to them and checked the connection to the monitor mounted on the wall, before turning it on.

“OK, then – let’s get started. What I want you to do, Lisa, is firstly, to stimulate yourself with your fingers, to get yourself a little heated up, then when you feel ready, climb onto the sybian and ride it until you orgasm. Can you do that for me?”

Lisa just gave a quick little nod, her thoughts already dispersed elsewhere. Between the odd feel of those chains, the pinch of their attach points, and the overall strange feeling coming over her... Thinking on just one particular thing seemed rather impossible. She bit her lip gently as he ran his fingers over the purple thing beside her, shivering with a little whimper as he gave her the excess against her opened sex. Her fingers tightened once again, afraid now she'd start leaving little nail marks in the bench.

She watched curiously as he placed a bunch of different stickers against her skin, a mix of a giggle and purr leaving her lips as the feel of them. The wires got a rather frightened glance as he hooked them in, Lisa reminding herself that this was still a medical test- no matter how odd it had started.

Lisa's eyes widened a bit as he explained the next part of his procedure, her thighs tensing together slightly as she whimpered. "Y-yes, Doctor." She drew her hand from the bench, placing it between her thighs, running her fingers gently against her folds. Her gaze was locked at the floor at first, her lips tightened together to keep from making too much noise as she traced upward. Fingertips rubbed against her clit, massaging it a moment and drawing a moan from her throat.

She looked up. She stared at the Doctor.
Her mouth opened, another heavy gasp leaving her as she slid her fingers back down, achingly testing them into her wetness. Her thumb teased still, tracing tiny circles as her digits pressed inside, lustful groans leaving the young woman.

He had warned the shot would make it easier for her to get aroused... She- she was already dripping onto his bench...

"Nnuh-" She pulled her hand away, hips rocking into the bench in frustration before she quickly turned her attention to that curious purple thing and the box it sat upon. Straddling over it, she eased down onto the toy, crying out happily as it filled her. Settled into her spot, she glanced over at him as he held the little remote attached. "Th-this doesn't... go too wild, does it, Doc?," She asked softly, rocking down against it and whimpering again.

Dan was very pleased with how this was going.
Lisa was proving most pliable and willing to try new things – just what he was looking for.

Dan connected the control box to the sybian and held it up.
“Don’t worry – this will only go as fast as we want. Maybe I should give it to you so you can control your pleasure? It would be better for the test that way, I think. Don’t you?”

He gazed down between her legs, at the juncture of her pussy and the purple jelly dong on the sybian.
“Maybe you need something to motivate you?”
Dan unzipped his trousers, and fished his cock through his fly.
“I think you should suck me as you fuck yourself, don’t you?”

Dan was already getting hot under the collar - she was unbelievable! He hjoed after this she would be ready for more. He had some much more he wanted to try with her.

 

[Mephistophelily]

"Ah-Alright..." Lisa nodded slowly as he offered her the controls, glancing over at them as he placed them beside her on the stand. Swallowing hard, she reached out for them, twisting the knob on it just slightly, a surprised gasp leaving her as the thing beneath her picked up its speed. Her other hand slapped down hard against the front of the machine, Lisa's mouth nearly hanging open at the new faster motions. Oh, good god-!

She glanced over at him as he took in his subject, still trying to regain her breath from the initial shock of how one little twist of the knob had done that. It had barely been a few marks on the dial-!

"Maybe you need something to motivate you?"

"H-Hah?" Lisa looked up at him quizzically, still clutching to the machine for dear life. The meaning of his question was made clear as he undid his pants, stepping closer to her as he let his length pull from the opening.

“I think you should suck me as you fuck yourself, don’t you?”

She swallowed again, panting as the toy drove into her, staring up at her doctor for a moment before giving a quick wanting whine and leaning toward him. Her lips glided down along his shaft, her groans muffled as she sucked against him. Soon she developed a helping rhythm- rock her hips down on the machine, then her mouth against him. Back and forth, both parts of her adding to her bliss. A deep moan echoed in her throat as she continued this, a hand flailing out to try and find another speed on his controls for the box.

 

[DanFS]

“Does that feel good, Lisa?”

Dan slid forward slightly feeding her even more of his cock, and moaning with her, as her moans stimulated him.
Her rhythm was superb – she had started to learn great control and was obviously satisfying herself as well as him.
He wanted to see if she would be able to deep-throat him, so he half-stepped forward, forcing the rest of his cock into her warm, wet mouth.
As she gagged, he felt her throat constrict and groaned lustily, as his cock swelled in response.
“Oh, Yes! Take it all, my little slut!” Dan moaned, through gritted teeth.

 

[Mephistophelily]

"Hn-hnnn-!" Lisa whimpered loudly against her doctor, fingers locked tightly into the seat of the device he had let her take perch upon. The vibrations inside her were nearly overwhelming now, her body fighting to contain the pleasure rolling through her. This thing- what had he called it? It was something she'd heard vaguely before, mentioned on websites she'd stolen peeks at over the months... When her curiosities got the better of her, wanting to find out more on the things she knew were so...

"NNNN!!"
Her thoughts were broken, choking on his length as he buried deeply into her throat. She tried to keep from gagging, closing her eyes tightly and clenching her thighs against the saddle she sat upon as he thrusted into her now adjusting throat.

Lisa's noises grew louder, his growled words hitting her ears and causing her to redden even more- That word. The whole reference... It was something that threw her off, but at the same time... she liked it. It set something off inside her, something that wanted to live up to that reference.
His little slut.
Yes...

The acceptance of it caused her to howl out against him, her hips bucking down against the invading toy in need. She wanted more... she wanted release... Her eyes opened, looking up at him pleadingly as he used her mouth.

 

[DanFS]

As she looked up at him - howling around his cock, as he plundered her mouth, that did it for him.
"OK, my little slut - cum for me, cum as hard as you like, you must be ready by now. Those vibrationsmust be driving you wild!"

Then he grabbed hold of her hair and pulled her onto his cock, as far as he could, before releasing his seed into her throat.
He was so turned on, it took several pulses of his cum to drain him, for the moment at least.
He looked down at Lisa, she was covered in a sheen of sweat and panting around his softening cock, still in her mouth.

Her lingerie was clinging to her like a second skin, due to her exertions and he loved the look of her in it.

As he stepped back and let her relax and turn off the sybian, to compose herself he reflected on how fortunate he was.

As she sat there, a quivering wreck, he tucked himself back in and moved over to his desk in the other room, to examine the readings from the electrodes.

Now - what next?

 

[Mephistophelily]

"Hnnnnn-!," The howling whimper that came from her as he told her to give in was followed soon by her eyes starting to roll back, the shudder that ran through her leaving her easily pulled and used as he wished. His hands claiming her hair as he forced himself into her mouth- she gasped around him, gagging a bit before a sudden choke came as he flooded her throat. Choking it down as he came, her body continued to ride out her own overwhelming bliss as the toy beneath her refused to stop.

She collapsed down against the seat as he pulled free of her, panting and groaning as he reached down to turn off the knob beside her. A little thankful noise that could have been a 'thank you' left her lips, her tongue flicking out to trace against them and the lingering taste of her doctor.

Lisa glanced over at the door with sleepy eyes as he stepped out, finally just closing them as another shiver ran down her spine, a little groan leaking from her lips as she felt her own juices trailing down against her thighs. It had stopped... but she was still feeling it....

She felt like she wanted more already. After all that- she... she still wanted more?

"Oh god," She whispered out, rocking her head against her arm as she sprawled forward against the bench. It had to be that shot he had given her. He had warned it would cause some weird effects for her, leave her highly aroused... but to still be aching like this, after something like that? It had felt wonderful, absolutely. She'd never experienced anything like that before... and the things he said- ohhhh, the things he said... That had certainly added to it.

Her eyes opened again, looking back to the door anxiously. When was he going to come back? "Doctor...," She called softly, whimpering a little. "Doctor, please... I-I need you..."

 

[DanFS]

Dan typed into his screen, the observations:
As expected, the injection had heightened Lisa's responses, to all stimuli. She was fast becoming a nymphomaniac!
Her first encounter with the sybian went as expected as well. She was taken a bit unawares, but soon got into it.
Becoming receptive to suggestions of more extreme behaviours and willingly submitted to other tasks.

He then heard Lisa call form the other room, and hit 'LogOff'.

"What do you want Lisa?" He asked, innocently.

 

[Mephistophelily]

Lisa whimpered softly as he returned and peered at her, seemingly unphased by her current state. She groaned weakly, sitting up slightly from her stretch, the clips and chains left on her tugging and reminding with every motion. Her lips rubbed together for a moment, staring at him with needing eyes before finally speaking.

"I want more, Doctor. Please. Whatever you gave me- I- please, your little slut needs to be fucked, please!" There was nearly a whine in her words as she begged to him, the shot her had given her leaving her twisted with ache. Even though the toy he'd given her a run on was amazing- very amazing, in fact- it had only seemed to wind her up more once she thought she had calmed.

It was still there.
Stronger, almost.
Was it because of those words? The ones she no longer blushed to repeat back?

"Please, sir... Use your little slut...."
Lisa choked out the words, staring at him still.

This was... Was... She felt a part of her cringing inside with it. But another, a larger, overwhelming side to her, was in heaven.
