Prologue

The lab tech pricked Special Agent Ellen Turrell’s finger and applied the test strip. “We’ve got a positive,” the lab tech announced.

“Good,” Dr. Weaver replied. “Go ahead and draw a vial. We’ll start sequencing right away.”

“Please don’t waste any time,” Ellen told the doctor. “Intel suggests that whatever’s happening, it’s going to happen very soon. We can’t spare a moment.” The doctor nodded.

The asset was a biologist, deep undercover in a domestic terrorist cell. She was guarded twenty-four hours a day: no phone, no Internet, no paper. The only way that she could pass a message to the FBI was with the same equipment she was using to create biological weapons for her captors: she had to smuggle her message in the inert amino acids of a harmless virus: 131 bits or fewer of Huffman-coded text. Then, all she had to do was find a way to pass that virus along...

November 17

Special Agent Ellen Turrell was tired, but she had a job to do. She had already been fucked twice. That was after her fellow swinger Peg had fingered her with rough nails, so she was a bit sore. That was probably for the best though: a couple abrasions in her vagina would ensure that she contracted the virus, if one of her partners had it.

Still, she hadn’t made contact with her main target - the one the mathematicians said had the highest coefficient of transmission. Anything caught by one member of her swinging club would eventually be passed on to all of them, but things were happening in the case, and Ellen was worried that next week might be too late.

“Henry,” Ellen said as the district attorney walked past her toward the coat room. The reflective dress she was wearing guaranteed that she would catch a man’s eye, and her pageant-eligible curves guaranteed she’d hold his attention. “I was hoping I’d run into you. I’ve got a taste for something only you can give me.” She stepped in close and put her champaign glass to his lips. He obliged her with a sip.

“Ellen,” he said, kissing her lips, “I wish I found you sooner. I think I’m all tapped out. I’ve done it twice tonight, and I’ve got a new girl on the side who’s been sapping my strength.” He looked down into her cleavage lecherously. “The spirit is willing, but, you know, the flesh is weak.”

Ellen grabbed his crotch and manipulated it with expert fingers. “I don’t think your flesh is so weak. It feels strong to me,” she said as his cock reluctantly responded to her touch.

“Ellen...,” Henry tried to argue. It was no good - she knelt in front of him, pulled down his pants, and began sucking his dick, in the foyer of their host’s manor. Looking down the length of his tie, Henry saw her sapphire eyes looking back at him, her hotrod-red lips wrapped around his cock, and the tops of her white round tits, pushed together by her dress.

“Promise me you’ll fuck me,” Ellen demanded.

Henry groaned.

Ellen summoned up more saliva and gave Henry some more loud wet sucks. “Promise me you’ll fuck me!” She insisted again.

“Of course I’ll fuck you!” Henry gave in.

Henry held out his hands for Ellen’s and helped her to her feet, and then he led her to the wall, just a few feet from the main door. Plenty of people were passing nearby, or loitering, but nobody gawked. He pulled her dress up to her waist. Unsurprisingly, her panties hadn’t survived this late into the night. He lifted one of her legs up, hooking her knee with his elbow, and then maneuvered his prick into her well-used cunt.

“Uh!” Ellen gasped as he thrust into her. Despite the tenderness that had been bothering her between lovers, Ellen’s pussy was eager for another round. More pounding, more sperm - yes, her body approved. She felt a shock of pleasure from her clit every time he pushed into her.

Soon the wall was thumping as his determined thrusts knocked her against it. “Oh dear god, yes!” Ellen cried. She closed her eyes and wrapped her arms around his neck tighter as she came.

“That might be all I can manage,” Henry told her apologetically when her eyes opened.

Ellen shook her head. “Not good enough,” she said. “I’m not letting you go before I get my fair share of your seed.”

“I don’t think I can,” Henry protested, but he didn’t stop fucking.

Ellen caught the attention of a pretty young woman she didn’t know. “Pardon me,” she said, “would you mind giving my friend’s prostate a little encouragement?”

“Sure,” the young woman said.

The new woman knelt behind Henry and sucked on her finger before wiggling it up his ass. Once she had found the right spot, she employed her other hand fondling his balls. Then the finger in his rectum began tapping on his little hard gland.

“Oh dear god I need to come!” Henry grunted.

“You will,” Ellen told him. “You should see this little cutie with her finger up your butt,” she added. “She can’t be more than twenty-two. You know, I bet you could use someone like her on your campaign staff.”

Henry’s cock and balls ached with the need for a climax that wouldn’t come. The young curly-haired woman’s percussion on his prostate gland squeezed out whatever tiny drops of fluid his body had left in reserve.

“Get ready, okay?” Ellen said, her eyes closing again. “I’m almost there. Hit me as hard as you can, okay?” She added, looking at the girl helping her, “You too.”

Henry obeyed and drove his sex-hammer as deep and hard into her as he could manage. “Oh! Oh! Oh!” Ellen cried out. “Uh! Uh! Uh! Uheeeeeeee!” She screamed. Her pussy squeezed Henry’s tired cock. The curly-haired girl pushed her finger hard into his prostate, and Henry came with a bellow.

His spasming dick managed to deliver only a few drops of feeble semen, but those drops contained more than enough of the undercover virologist’s custom virus to infect the FBI agent.

November 15

“Come on - let’s get you to bed before the pill kicks in,” District Attorney Henry Tudyk told his wife as they entered their home from the garage. She was already sleepy - enough that he had to support her as they walked.

“Hey Ally,” he said to the babysitter as they passed by the living room. “I’ll settle up with you in a minute, once I get Sharon to bed.”

Henry took his wife upstairs to their bedroom, and performed most of the task of undressing her himself. It had just been a casual night out with friends, so she didn’t have any makeup to remove, but he did struggle a little with her earrings. He left her naked, face-up on the bed.

Ally grinned as she watched Henry descend the steps. “So, are you going to ‘settle up’ with me now?” She asked with a devilish smile. She removed the headband holding her dirty blond hair back and ran her fingers through it.

“First things first,” Henry said. He sat on the couch with her and handed her some bills. “Here’s your payment for babysitting. You are now off-the-clock. You can leave now, or...”

“Or...,” Ally repeated before crawling into his lap and kissing him. “It is so hard waiting for you to come home,” she added during a short face-sucking break.

Ally stood up and began to take off her jeans.

“Wait,” Henry told her. “Let’s do something a little different this time.”

Henry led the lustful girl up to his bedroom and began undressing.

Ally looked at the naked woman on the bed. “What, so you want your wife to watch?” She asked.

“Believe me, after a half-bottle of champaign and a Xanax, she will not be waking up,” Henry told her. “Consider this just an exotic change of scenery.”

Ally accepted his assurance and began undressing, beginning with her flannel outer shirt. “Must have been some party,” she remarked.

Henry sat on the bed, next to his sleeping wife, and motioned for Ally to join him. “She doesn’t drink much at parties,” he told her. “This was just a get-together with another couple. That’s when she really cuts loose.”

The D.A. and the babysitter kissed, and he groped her teenage body. Ally’s eyes kept darting to the naked woman beside her. “She’s got amazing breasts,” she observed once Henry’s teeth released her lip. “I hope when I’m her age mine look that good.”

“Choose the right career, marry well, and such luxuries will be well within your means,” Henry told her. When Ally’s attention didn’t return to him, he added, “Go ahead and touch them if you want.”

Ally put her left hand on Sharon’s breast. She squeezed, feeling its surgically-augmented springiness. She moved her right hand to her own breast, for comparison, squeezing both. Apart from the significant size difference, they seemed the same. Henry took the opportunity to affix his mouth to Ally’s other nipple.

Ally could feel the wetness seeping out of her crotch. Her body was screaming its readiness for sex, but her fascination with the older woman had priority. Ally moved her hand to the sleeping woman’s bare mound. “She’s got no razor stubble,” the younger woman observed.

“Electrolysis,” Henry muttered before returning his mouth to Ally’s tit. His hands were rubbing her ass and thigh.

“Do you ever do her when she’s like this?” Ally asked.

“Once, with her permission ahead of time,” Henry told her. “Honestly it’s not very much fun.”

As if to test Henry’s assertion, Ally wiggled a finger into Sharon’s pussy. The sleeping woman wasn’t producing much lubrication. Ally could see why trying to stick a cock in there would be more trouble than it was worth.

“Okay, fuck me now,” Ally said, returning her attention the man who was making her own pussy gush. “How do you want me?”

“On your back,” Henry answered.

Ally lay back. Henry sat between her legs and penetrated her. He rolled his hips, thrusting into her, as he looked down on her smiling face, next to his sleeping wife.

“Oh yes, I want it! Do me forever!” The teen girl groaned, being sure to keep her voice down to avoid waking six-year-old Michael in the other room. Henry continued to fuck her while she wiggled beneath him, moaning, “Oh this feels so good. Your dick is wonderful!”

Henry was panting. Their bodies were making wet slopping sounds together. “I wish I had a daughter,” he blurted without thinking.

Ally giggled. “Is that what this is?” She asked, smiling. She glanced at the unconscious naked woman beside her. “The three of us in bed together? One big happy family?” She giggled again, “Oh daddy, fuck me harder! Make your little girl come, just like you did on my thirteenth birthday!”

Henry realized that he was losing control too late. He tried to hold it back but his ejaculation gushed into his teen lover, each pulse adding more to the soupy mess just outside her uterus.

Henry lay next to the girl and panted. He turned his head to face hers, inches from him. “What’s wrong?”

Ally tried not to sound disappointed. “I like that you got so excited and everything,” she told Henry. “I just really wanted to come.”

“Sorry. That one surprised me,” Henry said. “Go clean up. I’ll take care of you.”

Ally went to the bathroom to pee, and to get rid of the bulk of Henry’s mess from inside her. When she returned, Henry was still lying in the same position. He gestured to her, and so she followed his instructions and knelt over his face.

Ally’s body had largely relaxed from the excitement of sex, but after a few strokes of Henry’s tongue against her clit, she was once again a sexual reactor ready to explode. “Holy fuck! This is amazing,” she remarked, leaning forward and hanging on the bed’s headboard.

Soon Ally’s hips were moving around beyond her control, smashing into Henry’s face and breaking free from his tongue. He kept her going, somehow. And then Henry’s fingers entered her snatch, pumping furiously. Ally lost it: an orgasm different than any she had ever experienced, and far better, overtook her, causing her whole body to flail. Fluid sprayed in five spurts all over Henry’s face.

Henry wiped his eye after the sated girl climbed off of him. Her girl-come had struck him faster than his blink reflex could act. It carried with it the coded-message virus, which infected the district attorney.

November 11

Ally Prescott appeared in the hospital room’s doorway wearing her cheer uniform. Her dirty blond bob cut was held back by a headband with a checkerboard pattern of the school colors. Hiro Matsuda clicked the power button on the TV’s remote.

Ally approached the bed-ridden boy. “So I guess you’ve had a ton of people in here already telling you how awesome that catch was - how we’ve got a shot at the championship because of you,” she said.

“Yeah,” Hiro said with a smile. “Everyone has been really cool. I’m lucky to have great teammates and classmates.”

Ally put her hand on his knee. “Well, the girls were talking,” she said. Her hand hand slithered up his thigh, under the hem of his hospital gown. “We don’t think you’ve been thanked well enough.”

Ally seized Hiro’s balls authoritatively, and rolled them around in her hand. Hiro groaned and his dick began to grow.

“Rumor is you’re a virgin,” Ally said. She switched her grip to his now hard shaft. She held it tight and began a very subtle wanking.

“Uh huh,” Hiro replied dreamily.

“I’d like to be your first,” Ally said. “Would you be okay with that? Here like this?”

“Uh huh,” Hiro repeated.

Ally abandoned her spankies and panties on the floor, and then climbed onto the bed at Hiro’s feet. Straddling his legs, she crawled forward until she was sitting on his thighs. “Let me know if I hurt you, okay?” She told him.

She pushed his hospital gown forward to reveal his cock, balls, and black bush of pubic hair. She gave his shaft a few more strokes with her hand to make sure he was ready.

“Hey, um, can I see it?” Hiro asked with an enormous grin.

“What, this?” Ally teased. She rose up on her knees, leaned back, and lifted her uniform’s skirt, giving Hiro a view of her hairless pussy. She moved around in a little dance for him while he watched with childlike wonder. A drop of thin liquid escaped the top of his prick.

Ally grabbed his cock again and inched forward until the tip was resting between the folds of her puss, and then she moved again to capture it inside her. Hiro groaned again as she slowly swallowed his entire length with her cunt.

She ground her hips slowly, rubbing his cock with her inner sex tissues. His cock felt warm from her body heat, and wet. It felt welcome there. Beyond what their bodies were feeling, Hiro knew that Ally was fucking him every bit as much with her eyes.

Hiro reached out and touched Ally’s belly with his uninjured arm. Ally took his hand to her mouth and sucked on his thumb, in and out suggestively, coating it with her saliva. Then she moved his hand under her skirt, and pressed his thumb against her clit. She lifted her skirt while she rocked her body on top of him so that he could watch his hand pleasuring her through her little sex button.

They both moaned quietly, approaching climax as if casually rowing a boat there together. Ally muttered, “Oh, Hiro, you’re gonna make me come. Keep touching me like that. Oh yeah ... this is it! Oh!”

Ally’s pussy squeezed Hiro’s dick in urgent pulses, discordant with the serene mood up until that point. Her cheeks became rosy and she arched her back. The sight and the feeling overwhelmed Hiro. His cock twitched and shuttled many loads of vigorous sperm inside her.

They remained in their positions for a while, smiling at each other. Even when his dick was soft it was still inside her. When she did finally get up, Ally wiped between her legs with a hand full of tissues, and then went about licking up the dribbled mess from his balls and thighs. Hiro was hard again by the time Ally finished, and she was about to try getting him off with her mouth when there was a knock on the door, and they knew play time was over.

“Hey, um, I’m getting out of the hospital tomorrow. Do you think maybe we can get together this weekend?” Hiro asked while the nurse came in and inspected a clipboard.

“I’ve got to babysit this weekend,” Ally told him. “But soon for sure!”

The bulk of Hiro’s ejaculate had either seeped down his softening cock, or ended up in tissues in the trash, but much of the thin slippery part of the emulsion remained, coating the surfaces of Ally’s vagina. That fluid contained thousands of viruses carrying an encoded message, some of which found their way into Ally’s bloodstream.

November 8

Hiro Matsuda was on the operating table. Setting the bone from his break was straightforward for the medical team, but repairing the artery that had been damaged by the splintered bone required some delicacy. The blood he was given contained no harmful pathogens, but it did contain a virus, working its way through crowds of strangers toward the FBI. Hiro was unavoidably infected.

November 4

Medical student Kyle Dobson donated blood. He felt guilty about it, remembering that just last night he had engaged in what would definitely be considered “high risk” behavior, but he had a lot of expenses and not a lot of sources of income. Anyway, he had gotten the sense that the women he’d been with was high-class, not some street corner hooker. A call girl like that, Kyle figured, certainly gets tested regularly.
