The doctor

"What is it, Doctor?" I asked, turning to look in his wild, excited eyes.

"I've found it! I had hope when I saw a faint trace of antibodies in the last sample, but then I remembered something: I used the same latex gloves to handle the sample as I had used on you during your..um..post mission examination."

By post mission examination, he meant when he had me on the exam table spread eagle, his finger knuckle deep in my pussy as he breathed heavy and tried to not be obvious about it. He insisted on the check ups after each mission where I have an "encounter" as he calls them. I blush every time, even now.

"Lets go in the other room." He said, glancing over at the other two who weren't paying attention. I reluctantly follow him into the examination room and wince when I hear the door close behind us. "Don't you see? Its not in your blood at all. That's why none of the other serums have worked. Its your ..vaginal secretions. Something in there counteracts the virus! If we can synthesize it, then we can finally make a cure for the infected, and weapon against the ones too far gone!" He said, breathlessly.

I bit my lower lip. "Could it be?" I thought. I thought back to one of my first encounters. I was driving along the fence when I saw one that didn't look too banged up. It was male, mid thirties, and looked to only have a bite on one arm. Big, biker-looking guy. I pulled the car over, took a swig of bourbon and prepared myself. I was wearing a loose skirt, no panties, and long leather boots. It saw these first as I slowly got out of the car, the paleness of my thigh in sharp contrast with the black leather. I wore a leather corset top and long, black leather gloves that came up to mid bicep. On my ankle was a .38 and over my shoulder was an AR 15 **** rifle.

The gear not only protects me from "love bites", but tends to weather better than cloth in the field. I stood up, running my hands through my red hair, down my neck, and onto the swell of my breasts. It was desperately clawing at the fence, trying to get to me. Its erection bulged noticably in the tight jeans.

I looked up at the security camera and talked into the radio headset. "Okay Kyle, open gate 17 and let me out. He looks promising." I heard the metal lock click open ten yards down, and slowly made my way over to it. I slid out into the moonlit field as it shambled toward me, and closed the gate with a loud bang, securing the lock.
I walked over to an old, rotting horse trough, and put my hands on it, shaking my ass suggestively. It tore at its jeans, ripping the zipper open. The thick, pierced cock sprung out, already leaking cum. I spread my legs as I felt its hands on my shoulders, pulling me backward.

It wasn't aiming at my pussy, however. I gritted my teeth as I realized I was stuck. This hadn't happened before. I silently thanked God that they leaked as I felt his prickhead violently press itself into my ass. My breath came in short, choppy moans. It didn't care how much pain I was in as the full, pierced length of it slid deep inside my bowels. I wasn't getting wet now. It reached around me and squeezed my breasts hard, and that is when I saw it: a rainbow bracelet.

I would have laughed it I didn't have 8 inches of meat hammering in and out of my ass. I looked up at the camera. "Kyle, AHH! Ohh! Kyle, shoot this damned thing!" I said into the headset.

"Doctor says he wants to see what happens, see if it corrects itself on instinct." He said back. The pain ripped through my lower back as my legs gave out under its ****. I closed my eyes and couldn't talk as I felt the metal studs and ring thunder into my anus again and again, it cum leaking out of dozen piercings, running down my pussy lips. It was only then that I started to get wet. It tossed my to the ground and **** me to my knees, using a handful or hair and the AR 15 slung across my back as a handle it pumped in and out of ravaged ass.

They watched me get assfucked for close to an hour before it finally came, and even when it did it didn't slow down. I was raw and shaking like a leaf, but I managed to get ahold of my .38 when let go of my hair. I held the gun over my shoulder, and fired twice into his face, the shaking, spurting cock in my ass unloading all of its load from the shock.

The doctor spent a good amount time "examining" me that night.

"So then, my dear. Please get on the table." he said, already putting on his rubber gloves. Reluctantly, I climb onto the metal and stained wood of the exam table, and take a deep breath.
