Kimberly awoke naked on the lab table. The last she remembered was dozing off with her two friends at their small party at Tanya's college dorm room. She sees that they are both still with her, but strapped on two tables on either side of her. The entire wall was mirrored so she could see all of them. Both lanky teens were naked and stretched out as she was. Their arms went straight up to cuffs over their heads and their legs were slightly spread.
The tables were at an angle so Kimberly could see their whole bodies. The tables were designed to be used as flat surfaces but could be converted to gynecological examination mounts. As the other two slowly came to consciousness Kimberly observed the exposed genitalia of the girls. Little did each of them knew that the other had spent hours being probed and licked by their mutual friend. Even if their situation was bad at least she had a good view of the tasty young, barely furred slits of her teenaged friends. Beyond the wrist and ankle binding they also had a softly padded belt across their waists. Thus movement was very limited for the teen girls. When her friends finally became conscious enough to communicate they had no more recollection as to how they came to be there than her. They weren't uncomfortable but the situation seemed very strange and frankly they were very afraid.
After about a half an hour a young women in a lab coat entered the room. She examined their bonds but ignored them and their questions. She soon left and the girls were still no more informed as to why they were there than before. Soon she returned with a older male who was also dressed in a lab coat. The girls were very embarrassed but were still so completely ignored it quickly fated. They begged to be released and asked questions but the two stalwartly ignored them and talked.
"Which girl do you want to start with Doctor Clemson?" asked the woman. " I think we'll start with the nineteen-year-old on the end." He replied. "Lets do a variety of experimental runs. Doing the same procedure repeatedly is getting boring. The colonies have sent so many alien creatures doing unexpected things to girls for evaluation, lets give some of the new animals a try."
The girls were stunned. There were some rumors that most everyone discounted about these kinds of experiments. They were the kind of thing you told younger girls to scare the bejesus out of but girls of the three's age group had gone beyond believing that they were true. The two researchers moved to Tanya, the oldest of the three on the end, to Kimberly's right. Her legs were uncuffed and her feet placed in stirrups that were at the sides of the table. When her feet were bound in them the leg rest was lowered.
The part of the table under the girl's buttocks was missing like a normal gynecological exam table leaving her beautiful little skinny butt suspended in the air. The syrups were readjusted so they were parallel to the plane of the table and then pulled outward so that Tanya's knees were only slightly bent. Despite the flexibility of her young body this was a somewhat uncomfortable position. As she cried and struggled weakly she felt completely humiliated.
The older male pulled open her labia with one hand and then thrust two fingers of the other into her vagina coldly and unlubricated. As she screamed and jerked in response he ignored her and proceeded to examine her. Then with the same cold indifference he forced a finger completely into her anus without lubrication and felt around the inside of her rectum. Once, done he nodded to his female assistant to begin. She placed a shallow bowl under the girl's squirming rump on clamps, then the woman slid it up the adjustment rod so it her beautiful little rear set in it.
She left and returned shortly with a large container with the bio-hazard symbol on it. Opening it she reached in with a pair of tongs and tried to grab something. After a couple of attempts she finally got what she was fishing for. As she lifted it out the girls gasped in horror at the sight of the nearly meter long worm she held.
It wasn't like an earthworm but more like a marine worm. It was about three centimeters across and one thick. The flattened worm had rows of short legs in clusters on each side of its flattened body. To Tanya's extreme horror the young women dumped it in the bowl under the girl's butt. As she shrilly screamed in shock and fear it immediately oriented itself to the young girl's body.
As she valiantly squirmed against her bindings, crying and screaming, the animal probed at her bottom. It mouthed her buttocks and then finally found her exposed vaginal orifice. It eagerly explored her vagina by forcing it way into her for several centimeters. Unsatisfied it withdrew and, searching a little lower, discovered her tender little anal bud. It stopped and slowly mouthed at the rim of her anus and then into the opening itself. It's attention was intense and it tried to explorer deeper and deeper into the girl's hole.
Kimberly had a clear view of the animal, in the mirror, as it began to force itself into her friend's bucking bum. The anus was violently spasming in response to the creature's probing. The man's forceful examination the Tanya's anus had left it sensitized and tightly constricted. She now willed it even tighter to keep the thing from getting into her rectum. Finding that the girl's sphincter muscle resisted it attempts to enter her body the animal increased the intensity of its attack.
