"Jarod, look at this. They're dying."
"Dying? Why would they be dying?"
He looked at the blood slides again and saw that she was more than right. The bacteria was not just dying, they were deteriorating fast. In a matter of minutes, the alien life form was dying.
"It's like they have no ability to survive outside our body. That would mean that they can only be spread by direct body fluid transfer. Let's try saliva."
They prepared slides of their saliva. They saw that there was almost no bacteria in their mouths and what was there was dying already.
"What have we got?" Jarod asked rhetorically. "An alien bacteria that can't survive outside the body."
"It's concentrated in sexual fluids."
"We're infected and are suffering from incredibly strong sexual urges."
"Yet, our presence to each other is rank on the noses and physically painful with touch."
"You know Marie, it almost sounds like this bacteria is actively trying to keep us apart. But, it should want to spread, if it was intelligent. God! Listen to me. Smart bacteria. That's science fiction."
"Jarod. Science fiction can predict. Travel to the moon. Computers. Why not an intelligent bacteria? It does explain things. An intelligent bacteria would not want to spread to somewhere it already was. It would want to discourage two infected hosts from wasting resources."
"Possibly. But, this bacteria is not what the spores produced. Here, I'll show you."
Jarod created more spores and combined them on a slide to create the bacteria.
"See, this is different."
"Mutation?"
"It's not reproducing fast enough to produce a good mutation rate. Remember, most mutations are fatal. To produce a useful mutation, they would need to reproduce at hundreds of times this rate."
"It's a mystery. One thing is nice, it's made you healthier."
"Huh."
"You haven't had to use your inhaler for a few days. Haven't you noticed?"
"Inhaler..." Jarod was caught up in a memory. He remembered using his inhaler shortly after taking the growth samples. "Inhaler! Marie, you're a genius."
He took his inhaler and sprayed a burst on the spore produced bacteria and lookoed at it again under the microscope. The bacteria were reproducing at an accelerated rate.
"That's it. I was infected with the original, had an asthma attack, used my inhaler and something in the medicine jump started their growth. The enhanced growth led to faster mutations, resulting in a stable, beneficial mutation. Now the question is, what do we do?"
"Jarod, this is a disease that makes you crave sex and be repulsed by anyone you've had sex with once before. And we've potentially infected the town slut and a teenager. I can't think of two people better suited to spread this thing."
Several miles away, one of the two was doing just that. Kevin Sikes had been infected shortly before 7 PM. BY 8, he was at work at the Gas-n-Go store. The bacteria took no note of his activities, but spread throughout his body with maddening efficiency, their responses already programmed by the experience of having taken over Marie's systems. He was fully infected by 11Pm and started feeling the increase of arousal and desire in short order. If there was any group of people on the planet who would not notice the increase in sexual tension in their own bodies, it was teenage boys. Kevin simply chalked it up to the memory of Marie coming onto him so strongly.
As luck (the bad kind, that is) would have it, his girlfriend, 19 year old Shelly Whinsy, picked him up after work at midnight. They were already planning to go to her apartment for sex. Shelly had not even put the car into gear when Kevin reached over and began to stroke her upper thigh, edging near the unclad pussy that was barely covered by her short skirt.
"Kevin! You keep that up, you'll make me have an accident."
"I've been hard as a rock for over an hour and I can't stop thinking about the most beautiful girl in the world."
"Flattery will get you far, hot stuff. Seriously, though, it's hard to concentrate with you stoking me up like this. We've got all night. Now back that hand off. You can wait for fifteen minutes."
Kevin didn't pull his hand back, but he did ease it a ways from her cunt, letting her drive. They arrived at her house in the promised time frame. Shelly rented an upstairs flat from the Robinsons, an older couple that owned the house itself. She found the three rooms (not counting a small bathroom with only a shower) quite enough for her needs right now. Most important to her was that the Robinsons went to sleep early and could not be woken up by anything short of a thermonuclear device, or so it seemed. Perfect for fucking boyfriends.
Kevin was feeling a level of desperation he had never experienced before, well except for that one week when both hands had been bandaged from burns (gauze chafes!). They had just made it to the bottom of the stairs leading to her loft when Kevin pulled her to him and kissed her with a wet, sloppy kiss, his hands groping at her ass, pulling her up against his cock.
"My, you are in a bad way. I've never felt you that hard before." She reached her own hand down, feeling the steel rigidity of him. She squeezed a little and was rewarded by a groan from Kevin. While she has never been a fan of his kissing technique, she loved the attention he paid to her ass. As he kneaded her cheeks, she started breathing heavily and felt little traces of moisture beginning to form between her lags.
"Fuck, Shelly, it's almost painful. Can I get a blow tonight? I just know I'll be up for more soon."
Shelly made a, "Mmmmm," noise as she enjoyed the attention he was giving her. She just knew he was good for two, if not more, sets tonight, and, if he came soon, he'd take more time with her. "Sure, tiger. But we'll need to get upstairs. And remember, not in the mouth."
"I know, I know. I'll tell you in time."
They unclenched enough to stagger up the stairs to her rooms. Inside, they made tracks for her bed, a king size that left only two feet of clearance with the wall on two sides. It's a good thing that all she ever did in the room is sleep and fuck. She backed into the room and sat herself on the bed so she could reach his crotch easily. Undoing his pants, she let them drop and took his cock in her hands, stroking it to milk the precum from it, wiping it on the side of the sheet.
Cleared of the fluid she didn't like very much, she took a lick at the underside, watching his cock jerk at the sensation. She loved watching that, seeing the effect she could have on him. Kevin, groaning, fell back against the wall, thrusting his hips towards Shelly. She licked at it again, holding with one hand while the other fumbled with the buttons of her shirt. As she got the last button opened, letting her breasts peek out, barely contained in a half cup bra, she sank her mouth over his shaft. She used her mouth like a pussy, gripping his cock with warm moist lips, while she pulled her shirt and bra all the way off.
Kevin began to instinctively hump against her face, responding to the fire-like feelings coming from his cock. Little spasms were beginning to shake his body as he soared higher in arousal than he ever had before. He felt the swell start and barely got out, "Fuck! Fast! Cum!" before he jerked and exploded.
Shelly just got him out of her mouth and pointed down a little when the first jets of milky white semen splattered against her chest and neck. She had never seen him cum so hard and in such quantity before. Her stroked him through five full pulses of cum and was able to milk several more smaller amounts before he stopped producing. As Kevin sank back against the wall, Shelly rubbed the slick fluid over her chest and belly. She loved the way it felt, sliding over her skin, pulling at her skin like a tease as it dried slowly.
Her chest was cooling as the liquid portion of the mess on her dried. She reached up and pulled Kevin onto the bed next to her, entangling his head and arms in his shirt as she pulled it off over his head. As the t-shirt finally popped over his head, she smiled at the feel of his not fully flaccid cock against her leg. They grasped each other again, their mouths returning to one another. Kevin's hand slid down her side, catching her skirt and pulling it down to her knees. On it's way back up, it brushed against her pussy, dampening itself in her juices. He was rewarded by a long, deep moan.
