It all happened after her 18th birthday…

Maggie was a pretty average girl. She went to high school, and was going into her senior year. Active in both sports and arts, while still making A's, she was the ideal teen. She didn't have a boyfriend, but was pretty popular among the guys at her school, probably because of her stunning appearance.

Short, but not tiny, Maggie had natural-looking, tanned skin. Her dirty blonde hair sprouted from her head like a lion's mane, giving her a ferocious appearance. She wasn't particularly well-endowed in breast size, but her smooth, carmel skin and tight features still made her wildly attractive.

The day after she turned 18, Maggie went to her doctor for her yearly check-up.

"How are you today, Maggie?" said her smiling doctor as he led her down the hall to the exam room.

"I'm doing fine, thanks." replied Maggie. "Anything out of the ordinary we need to do today?"

"Nope." said the doctor reassuringly. "Today's just a plain old physical."

After entering the exam room, the doctor went about a normal exam on the teen. He checked her pulse, looked in her ears and down her throat, took her blood pressure, and tapped her knees to check her reflexes.

"Alright, Maggie, so far so good," said the doctor. "Now, I need to do a genital exam. Would you mind removing your pants and lying back on that table?"

"Sure," said Maggie.

The doctor quickly and professionally examined Maggie's hairless slit, then sat back down at his chair, typing notes into his computer.

"Well, Maggie, you seem to be in perfect health," the doctor said. "In fact, you're in such good health, that I'd like to recommend you as a subject for a medical study, with your permission, of course."

Maggie was intrigued. "What sort of test, doctor?"

"Well," replied the doctor. "The OB-GYN department is running it. They're collecting data to increase knowledge of teenage girl's sexual development, and they want healthy test subjects. Unfortunately, because the study has not been made public yet, I'm not privy to the exact details of the test." The doctor paused for a moment.  "However, I have been assured that the entire process should not be longer than an hour, and there are no short or long-term effects involved, everything happens right here. I should also mention that there is a small incentive for participating in the study, to the tune of $50 dollars."

Maggie thought for a moment. Although the test seemed a bit shady, she trusted her doctor that the whole thing could be done in one-shot with no after-effects, and, $50 was pretty generous for simply being a test subject in a harmless experiment.

"Alright," replied Maggie. "I'd be happy to participate! How soon can I come in?"

"Let's see here," said the doctor as he reviewed his schedule. "Well, if it works for you, we can schedule you in for this afternoon, in about 6 hours."

"That sounds fine," Maggie said. "Thanks for your help, doctor."

With that, Maggie left the office, and went out to the mall for the afternoon.

At 4pm, Maggie returned to the clinic, now following the signs towards the OB-GYN department.

Soon enough, Maggie found herself in a standard hospital waiting room, with a receptionist sitting at a desk.

"Ah!" exclaimed the receptionist as Maggie entered. "You must be Maggie! How nice to meet you!"

Maggie shook the enthusiastic woman's hand with casual indifference.

"Hi there." Maggie responded.

"Now, dear, I just have a few forms for you to fill out," said the receptionist as she slid a few forms across the desk to Maggie. "Just fill in what it tells you to, and then wait here for the doctor."

Maggie took the forms and filled them out. They were all mostly legal "consent" mumbo-jumbo. Maggie knew enough to not get sucked into a trap, and read the forms, but found that they were all reasonable, albeit vague, and put down her signature.

Right after Maggie finished the forms, a nurse poked her head through the doorway.

"Miss Maggie Williams?" called the nurse.

"Yes." said Maggie as she walked towards the nurse. "That'd be me."

"Lovely!" said the nurse. "Well, now that you've filled out all your paperwork, we can get right down to business."

The nurse led Maggie into a changing room with lockers, and a number of clean hospital gowns hanging on the wall.

"Now, dear, I'm going to have to ask you to remove your clothing and put on a gown. We're not trying to humiliate you, and I promise that everyone here is quite professional."

Maggie agreed and the nurse left the room as the teenage girl began to disrobe.

Maggie took off her shirt and shorts, so that she was standing in the room with just her bra and panties on. The girl's petite frame was tightly hugged by the lacy, black bra that concealed two visible mounds, as well as a matching pair of panties, which hugged the girl's tight buttcheeks like a vice.

Maggie took off her bra, exposing her small, brown nipples to the cool, hospital air. The sensitive nubs puckered, and stuck out firmly from the two growing breasts beneath them.

After removing her panties, Maggie put on the hospital gown, tying it tightly in the back, and walked out into the hallway to meet the nurse, who led her to a small room with a gynecological table inside.

Maggie eyed the table with interest as the nurse shut the door behind them.

"Alright now, dear." spoke the nurse. "Dr. Howards will be in in a moment. I'm going to ask you to take off your robe and lay back on the table here so I can strap you in."

Maggie eyed the nurse suspiciously as she took off the gown, exposing her tight, smooth body to the matronly woman.

"Strap me in?" Maggie asked as she hopped up on the table.

"Oh, yes, dear." replied the nurse. "It's just to make sure the equipment doesn't get knocked off you, I promise we won't do anything that will hurt."

"Alright then." said Maggie as she leaned her head back.

The nurse took Maggie's taut legs and put them in the stirrups that extended from the table, strapping them down at the ankle and the thigh. Then, she took a strap and pulled it across the table so that it came right below the young girl's rising and falling breasts, securing her midsection. She took Maggie's arms and strapped them down to the table at the elbow and the wrist. Finally, the nurse stepped back and looked at the immobile, carmel-skinned teen bound to the table before her.

At that moment, the door opened and a tall, dark haired woman entered. She looked young, not much older than 30, so Maggie guessed she must have been just out of med school.

As the woman shut the door behind her, and excused the nurse, she turned and smiled at Maggie, who now lay bound to the table, panting lightly.

"Hello, Miss WIlliams." said the woman. "My name is Dr. Howards, and I want to thank you so much for coming in today. What you're doing today is going to help us collect data that could be used to help billions of girls."

Maggie smiled a little, but kept silent, slightly embarrassed at her compromising position, with her nipples erect and her asshole and pussy proudly displayed, hovering slightly above the table.

"Maggie," said Dr. Howards. "What we're doing here today is called orgasm manipulation. We're exploring female ejaculation, and we want to find out what we can do to prolong it, so that we can get a sizable sample. Essentially, we'll have you stimulated until you orgasm, then we'll use equipment to prolong the climax, so that we can collect all the fluid you produce."

Maggie shifted uncomfortably, her small breasts jiggling slightly. "Um… I'm not sure if I'm entirely comfortable with that…" She said.

"Well, you did sign a binding contract just a few moments ago, so I'm afraid you don't have much choice now," said Dr. Howards.

Seeing Maggie's pained expression as she told her this news, the doctor quickly backtracked. "Of course, there really isn't anything to be uncomfortable with, we're both girls here, and I think you'll find the entire experience actually quite enjoyable."

Maggie tested the strength of the straps holding her down. She wasn't going anywhere until this woman got what she wanted. "Fine," retorted the bound teen.

"Excellent!" said the doctor. "Then lets go to the extraction room, shall we?"

"Extraction room?! But--" Maggie yelped.

Before the girl could finish her sentence, the doctor wheeled Maggie out of the exam room and into the hallway. Maggie closed her mouth, and shut her eyes in embarrassment as her smooth, bound body was wheeled through the hallways, her breasts shaking gently with the movement of the table.

The doctor wheeled Maggie through a pair of double doors, into a large room brimming with doctors and technicians running around.

From the corner of her eye, Maggie could see several other teen girls, all naked and bound to tables. Some were being wheeled from here to there, while others were being examined or were hooked up to machines.

The sounds of focused conversations and humming medical equipment filled the room, with the occasional moan or squeak being heard from the girls. The air was heavy with the hot, panting breaths of the girls, and the occasional whiff of cum and sweat.

Maggie was wheeled to a corner of the room, next to an array of carts, each with various machines and items on them. Maggie's pulse quickened at the sight of a machine that seemed to have dials to increase or decrease voltage on it.

As Dr. Howards parked the table, the technicians wasted no time in attaching the various machines and devices to Maggie's nubile body.

First, two clips were put on her nipples. They didn't hurt, but applied just enough pressure to stay on. Then, a series of TENS unit pads were put on her body, two on the insides of her thighs, one on her mons pubis, two on her buttcheeks, and two right above her pelvis. An EKG machine was wheeled up, and the small monitoring pads were placed on the teen's bare chest, right above her quivering breasts.

A small probed was pushed into Maggie's tight asshole, which made her buck her hips in argument.

"Hey! Stop it! I don't want anything in there!" yelled Maggie as the technicians pushed the bud into her small hole.

"Maggie, you signed a consent form. Now just relax and let us do our work." Dr. Howards replied curtly.

Maggie huffed and put her head back down, squaring her jaw, defiantly acquiescing to the doctor's demands.

Finally, the technicians took a large, oval suction cup and put it over Maggie's tight, shaved pussy.

The technicians wired the TENS pads, nipples clamps, and anal probe up to a small box with a dial. Then they screwed a small tube into the vaginal suction cup and attached the other end to a small machine with a collecting tank.

Maggie panted, jiggling the tubes and wires attached to her small body, and listening to her heartbeat via the beeps of the EKG machine.

Beep……. Beep…… Beep……

"Now, Maggie," said the doctor. "I need you to just relax and let your body respond naturally to all of this. I promise no pain will come to you."

Maggie closed her eyes and took a deep breath, her small breasts rising and falling.

"Begin stimulation." said Dr. Howards.

Immediately, Maggie felt her pussy pulled into a vacuum, her small clit responding to the attention. The anal probe hummed against the back of her g-spot, making her arch her back against the straps in pleasure. She could hear her heart rate increase over the moans of her joy.

Beep… Beep… Beep… Beep… Beep…

"Aaaah… Oo…Oo! Oh… God…" Maggie cooed.

The nipple clamps had kicked in by now, juicing her sensitive nubs with a gentle current, making her breasts alight with pleasure. Her heart rate increased.

Beep. Beep. Beep. Beep. Beep. Beep. Beep.

Dr. Howards watched Maggie get closer to her orgasm, the girl straining against her bonds, trying to get more out of the fantastic contraptions stimulating her young body. It wouldn't be long now…

"FUCK! FUCK! DOCTOR!!! I-- I'M GONNA C-- CUM!!!"

Maggie screamed in orgasmic pleasure as she arched higher than ever from the table, her heart rate going into oblivion.

BeepBeepBeepBeepBeepBeepBeepBeepBeepBeep

"Begin orgasm manipulation!" yelled the doctor to the technicians, who began to tinker with the machines.

Dr. Howards walked up to Maggie, who was right on the edge, arching higher, higher… The doctor placed a cool hand on Maggie's sweat drenched stomach, right above the suction cup madly sucking on the girl's labia and clitoris, and pressed lightly, massaging the area.

The doctor's hand was too much for the little girl to handle, and Maggie screamed louder, going into the throws of an orgasm.

The first wave of pleasure came up from inside her, crashing down in a cascade of sexual ecstasy. Maggie smiled and yelped in pure joy. Then another wave, and another, and another.

The doctor watched the small container attached to the suction machine as it filled with Maggie's sweet cum, sucked from her virgin orifice.

As the doctor saw Maggie begin the descent from her orgasm, she turned the dial on the TENS unit all the way up.

Just as Maggie thought her brilliant orgasm had come to an end, she suddenly felt the TENS pads activate, sending her thigh, pelvic, and anal muscles into rapid fire contractions, and making her orgasm suddenly flare up in intensity once more.

Maggie's lower half began to buck, squirm, and shake on the table, making it look like she was doing some sort of demented dance. Her butt slapped the surface of the table, and her breasts flailed wildly. Her eyes rolled into the back of her head, as her orgasm continued for an unnatural amount of time, and her vagina was sent into an oblivion of pleasure.

Low, guttural moans escaped Maggie's mouth as her orgasm went on and on, her head lolling back and forth. She made unnatural squeaks and shrieks as the TENS unit caused her to involuntarily shake. The suction cup on her vagina was making wet, squelching noises as the immense amount of cum the girl was producing weakened the suction lining.

Dr. Howards looked at the clock. Maggie had been orgasming for almost five minutes… She was amazed the girl had lasted this long.

Just as that thought crossed the doctor's mind, Maggie suddenly let out an ear-piercing scream, and passed out on the gynecological table, her head falling to the side, as the rest of her unconscious body continued to jitter and convulse from the TENS pads.

"Power down all machines!" yelled Dr. Howards as she saw Maggie pass out. The technicians turned the dials down, and the doctor watched as Maggie's orgasmic convulsions lessened. After all the machines were powered off, Maggie's body was still jittering erratically. Unconsciously, she was taking deep, filling breaths, making her nostrils flare, and showing off her ribcage under her quivering breasts. One foot was kicking and shaking, trying to escape the straps that bound it to the stirrups.

The technicians removed all of the pads and clips attached to Maggie's body. The girl had finally calmed down, and was now sleeping soundly, completely spent. The doctor took of the vaginal suction cup. The girl's wet, slippery, engorged labia spilled out from underneath it, dripping with her juices and letting a small trickle of cum leak out, down to her asshole. Dr. Howards was amazed with how large the girl's clitoris had become, almost three times its original size.

Dr. Howards made some notes in her pocketbook, and then wheeled Maggie to a washroom right next to the locker room. She took a warm, soapy sponge and cleaned the girl's sweat-drenched skin. Toweling Maggie off, she picked up the girl in a fireman's cradle and laid her down in a bed to rest.

A few hours later, Maggie awoke, slightly sore around her stretched labia, but for the most part, content and sexually spent. She smiled at the receptionist as she received her compensation. $50 for the best sexual experience of her life? Worth it.
