Elizabeth was in the doctor's waiting room idly thumbing through last week's issue of TIME magazine when she heard her name being called by the nurse. She was there for a routine rectal exam as part of her annual physical exam. She didn't exactly care for this type of exam (who does?) but knew that it was a necessary evil that needed to be done for her own good because her family medical history showed a problem with bleeding hemorroids in her family. Her old regular doctor had retired recently so this was her first visit to this particular doctor. She didn't know what to expect with this new guy. She was a relatively shy and modest woman and so she hoped this exam wouldn't take too long because she knew that she would have to be partially nude for it. She always felt uneasy being naked in front of male doctors because she couldn't help but wonder what they were thinking about while they probed and touched her most intimate regions. The nurse took Elizabeth through the usual prelim activity of weighing her, taking her temperature and blood pressure, etc. After that, the nurse escorted her to a vacant exam room. It looked like every other exam room she had ever seen. It had an exam table, a sink, a couple of chairs and some cabinets filled with medical paraphenalia. The nurse handed Elizabeth one of those flimsy paper gowns and instructed her to disrobe from the waist down and wait for the doctor. Then the nurse left the room. Elizabeth looked at herself in the mirror as most women do and sort of liked what she saw. She was 51 but the years had been kind to her. She was a married woman and she and her husband Nick were quite happy together. Because she watched her weight and exercised regularly, she was in fairly good shape for a woman of her age. At 5' 4", she weighed about 130 lbs with a very slightly plump but shapely figure with nice legs. Like a lot of women, she thought that her hips and ass were too big and her titties were too small. But she noticed that she still got approving stares and an occasional wolf whistle from men whenever she wore skirts or shorts in the summertime. That always made her feel good! Elizabeth removed her jeans and then slid her white cotton panties down her hips. She laid the clothing on a chair and stood there totally nude from the waist down. She then bent over to take off her shoes. Just then the door opened. She looked over her shoulder and saw that it was the doctor! Apparently he had thought that she was ready for the exam. Elizabeth realized that he obviously got a good view of her bare ass and probably her pussy as she was bent over. She was slightly embarrassed by this. The doctor apologized for the intrusion and left. The room was cold and she could feel goosebumps starting to form on her legs, belly and ass. She then quickly donned the paper gown and hopped up onto the table to wait for the doctor to come back. The doctor came back into the room after a few more minutes and shut the door. He introduced himself as Doctor Boswell. Elizabeth was very surprised at how young he appeared to be. To her, he didn't look much older than most college boys. The doctor was about 6' tall, was handsome in a boyish way and had the appearance of someone who liked the outdoors because he was well-tanned and had a healthy athletic look about him. He engaged her in the usual doctor-patient small talk for a short time while he scribbled on his notepad. Then he got down to the business at hand. Doctor Boswell instructed Elizabeth to lay back on the table and then turn onto her left side with her knees up toward her chest. As she rolled over, the paper gown moved up her hips and her round plump ass soon became fully exposed to the cold air. She assumed that the doctor was now getting a great view of her ass and pussy with its abundant growth of curly pubic hair as she turned over onto her side. The doctor sat down on his rolling chair and moved towards the table. He squeezed a generous glop of K-Y Jelly onto a finger. Then he reached over and spread the cheeks of her ass. He proceeded to lubricate her asshole real good so he could insert the anoscope without problems. The doctor's finger slipped just a bit as he was inserting his finger and accidently touched her pussy. The jelly felt cold on her asshole and pussy lips and she flinched just a bit. He finished the lubrication and got the anoscope ready for insertion into her asshole. The doctor slowly pushed the anoscope up into her asshole. It was slightly uncomfortable at first but Elizabeth soon got used to it. He laid a hand on one cheek of her ass as he was peering into the anoscope. In past exams, she had always felt somewhat awkward and vulnerable whenever she was exposed and touched in this way during a doctor's exam. But, for some reason, this doctor's touch felt rather pleasant so she started to relax a bit while he was probing her ass. Her previous doctor had been a much older man so she never had any sexual feelings whenever he had examined her. But, the fact that this doctor was young and handsome and was now looking at her fully exposed ass and pussy stirred up an unexpected bit of sexual excitement within her. She knew that he had a great view of her pussy and its thick and curly brunette pubic hair. So she decided that she would have some harmless fun and give him and herself a little thrill. She moved her right leg up ever so slightly to give him a better view of her womanly goodies. She tried to make this look like a natural shifting of body position and nothing more. As the exam progressed, Elizabeth noticed that the doctor's hand was rubbing and squeezing her ass cheek very slightly. She was surprised by that but liked the way it felt. He finally finished the exam and slowly pulled out the anoscope out of her asshole. He got up and walked over to a drawer to get some paper towels. As he did, she could see him out of the corner of her eye. She saw that he had a big bulge in his pants! He had gotten an erection at the sight of her nakedness! This startled her and caused feelings of uncertainty within her. Should she stay quiet or say something to him about it?
