After her first exam, Jessica visited Dr. Thoren regularly. After a few months of 'exams,' Dr. Thoren started teaching Jessica to help him with other things. She learned how to weigh and measure a patient and take their blood pressure. Then she learned how to use a stethoscope and started listening to hearts and lungs and even hooking patients up for their EKG. Finally, Jessica started helping with more intimate parts of exams.
She enjoyed holding a patient's labia spread while Dr. Thoren worked inside their vagina. He taught her the various types of speculums like Graves, Pedersen, and Collin. Her favorite, though, was when he asked her to hold a patient's butt cheeks open for a rectal temperature or a rectal exam. The best was when they squirmed and she had to hold them down.
Another benefit of working with Dr. Thoren was being able to slip into empty exam rooms and explore. She was almost sure he had cameras in the rooms, but she didn't care. The thought of him watching her turned her on almost as much as playing with the equipment.
The first time she had played alone in a room was after about six months of regular sessions with the doctor. While he was doing paperwork she had snuck into a room. Just the feeling of sneaking around gave her a rush. What if she got caught? Soon, though, this became a regular part of her routine.
One day she went into a room, like she always did, turned on the lights, and picked a stethoscope from a drawer. After undressing to her bra and panties she put the earpieces in her ears and listened to her chest. She took some deep breaths, enjoying the sound of the air rushing in and out of her lungs.
Then she listened for her heartbeat, putting the stethoscope between her breasts like Dr. Thoren often did. Lub-dub, lub-dub. It was a soothing sound, and she listened for a long time. Standing there in the exam room, and figuring she was alone, she put one hand into her panties and began to play with herself. As expected her heart beat faster
She had never hooked herself up to the EKG, so she decided today was the day to try it. After making sure all the lead wires had electrodes attached, she slipped off her bra and sat down on the table. Carefully, she pulled the backing off the first electrode and stuck it to her chest below her left breast. Then she did the others, below the other breast, above her breasts, and one in between her breasts.
She turned on the monitor and it began a steady beeping in time with her heart. Her heart rate on the screen said 86, and the green lines traced a steady sinus rhythm. She put the stethoscope back in her ears and began to listen to how her heart beat in time with the monitor. Laying back she closed her eyes and relaxed to the sound of her own heart.
Then she had a thought. How fast would her heart rate get during orgasm, she wondered. She kicked off her panties, spread her legs, and began to touch herself again. The EKG picked up speed, so she began to play more aggressively with her clit. With one hand holding the stethoscope to her chest and the other playing with her clit she moaned in pleasure.
Deciding she needed two hands for her pussy, she took a piece of medical tape and fixed the head of the stethoscope to her chest. Now she had one hand for her clit, and the other one sent two fingers inside her pussy. This was heaven, and she began to get wet.
She recalled her first exam with Dr. Thoren and how he had used the speculum like a large metal dildo. It had made her feel fantastically full. Rummaging through the drawer at the foot of the table she found a large Collin speculum. Dr. Thoren didn't use these often because they were so big, but it seemed just right for her now. With one hand she spread her labia while the other hand eased the large instrument into her pussy. It took her a while to insert it all the way, but she finally got the entire speculum in up to the flanges at the front and opened it as far as she could tolerate.
She resumed stroking her clit with one hand while the other one played with the speculum. With her eyes closed she played and listened to her heartbeat faster and faster. Just when she was sure she was going to cum she heard a noise. Startled, she opened her eyes.
"Having some fun, Jessica?" It was Dr. Thoren. She hadn't heard him come in.
"I'm sorry, doctor," she stammered. She was too shocked to even take the stethoscope out of her ears.
"Don't be sorry," He said in a reassuring voice. "I don't mind you having a little fun, but since I'm here let's have fun together."
"Ok, doctor," she said, wondering what he had in store for her.
Without removing the speculum he flipped her on her side facing away from him, and spread lube on her back passage. Then something large entered her anus and moved upward. It was larger than a thermometer, and it wasn't the doctor's finger.
"What's that, doctor?" She asked, her heart racing.
"This is a proctoscope. It's used for examining the rectum, but it can be a fun toy." He guided her hand to the scope, and she began to pull in and out while her other hand did the same with the speculum in her pussy.
"I think we need to fill all 3 holes, don't you Jessica?" Wearing nothing but a lab coat he walked around the side of the table so he was facing her.
"Yes, doctor," she said and opened her mouth wide. He slid his cock in until the whole shaft was in her mouth.
With all of her holes occupied, two by medical instruments and one by Dr. Thoren's massive cock, it wasn't long before an orgasm built within her. The sound of her heart through the stethoscope mesmerized her while the speculum in her pussy and the proctoscope up her ass built steady heat within her.
"Cum for me like a good girl," he said.
With that, she orgasmed, screaming with her mouth still full of his cock. When she had finished he pulled himself out of her mouth and aimed his thick member at her face. With a few strokes, a giant load of hot cum flew out and covered Jessica's face.
She was startled by the shower of sticky liquid. Both her boyfriend, Ryan, and Dr. Thoren had cum in her mouth before, but she'd never had cum on her face. It was a little embarrassing, but hot at the same time. She liked it when he treated her like a slut.
"Am I a slut, doctor?"
"No, you're my special little girl. Only very good girls get that," he said.
"Thank you, doctor. I like being your little girl."
Despite being covered in the doctor's seed she turned her head to see the EKG screen. 160 beats per minute showed in the corner of the screen while the green lines were full of sharp peaks.
Once she was cleaned up and they were both dressed she turned to leave, but Dr. Thoren stopped her.
"The reason I came looking for you is because I need an assistant for a lecture I'm giving next week," he said to her.
"I'm not sure how I can help," she replied.
"Well, it's a lecture on examination and stimulation of young women who are fully developed but have never been pregnant," he started. "We had a model scheduled, but she bailed. I was hoping you might fill in."
She wasn't sure about this.
