Humanity, 2.0

Year 1, Day 28

Emily’s condition didn’t get worse per se; instead, it seemed like she simply had less energy every hour until she was either sleeping or eating almost all the time. The retrovirus was at work, I knew, turning her into one of us, but I had no idea how long that would take. She kept telling me to leave and that she didn’t want me to catch whatever it was, and I didn’t quite want to have that conversation with her yet – of course, there was no possibility I could ‘catch it’. It was my own body that created it.

Six days had passed and I had mostly spent my time in between caring for Emily with books or the internet. My apartment wasn’t far away, so it didn’t long to drop in there to get changes of clothes and such. I saw John once in the interim, but only for a few minutes. He didn’t seem to notice anything different about me. Finally, after days of agonizing over whether or not I should do it, I decided. I picked up my cell and called Bethany. It rang a few times until I heard it pick up, something clattering loudly on the other end – probably the phone itself – then it being picked up again.

“Ben! Are you back yet? I need to see you.”

“I just got back in half a day ago. What about?”

“I need you to tell me exactly what you were doing and where you did it before you got sick. Something is really fucked up about your DNA.”

“Uh, okay.” My mind raced. How much did she know now? “So that’s the medical term for it?“

“Sorry. Something is really unusual, and I can’t figure it out. I mean, it’s obviously not infectious, since, uhh…” She trailed off for a moment. My mind instantly wandered back to that first, amazing blowjob of my new life that she had given me. “Just come by my place and I’ll show you.”

I took a breath despite myself; she didn’t know much, from the sound of it. “Your place? Not your office?”

“I don’t have an office right now. I’ve been working out of my house. I’ll text the address to you again if you don’t have my card. You need to see all this and we need to decide what to do next.”

I followed the directions, but was worried the whole time that Bethany had found me out and reported my impossible DNA to someone in authority, and I was heading into some kind of trap. The Experimenter’s plan might end before even a month was out. There were no black helicopters circling her house, fortunately. It was an impressive place, actually – three-car garage, probably four or five bedrooms and at least an acre of land. It had a quaint Tudor-style exterior and the lot was wooded; the closest other house was at least a hundred paces away. From where I stood at the curb, it even looked like it had a basement. I walked up front and center down the driveway, making myself really obvious, then rang the doorbell.

She answered, this time without her big doctor’s jacket on. She didn’t look as professional as at the hospital – or at least, as professional as when she’d walked into my suite – but she was easily just as good-looking. The same short-bob brunette hair, sharp nose, and now she had glasses on – a new addition. I guessed she’d been wearing contacts at the hospital. She had plain navy-blue sweatpants on with no shoes, and a shapeless red sweatshirt that read ‘Clemson U’ on it. I wondered if she went there. The outfit, oddly, somehow made her look younger… maybe it was the haphazard, thrown-on look without regard for prettying herself up that you would see on some coed cramming for her exams. I myself had on just another pair of khakis and a button-down shirt, a light jacket and walking shoes; another day in Sacramento.

“Ben!” She grabbed me by the arm and roughly yanked me inside. She looked around outside for a few moments before closing the door, like she was going to sell me drugs and the cops might show. She pulled me inside a few paces, then turned around. I never got a good feel in the hospital for how short she was… Bethany was actually quite petite. The sweatshirt was a size or two too large, and only her fingers stuck out of the ends of the sleeves. With the reading glasses on and her hair also a little frizzy, she looked adorable. “Where have you been!

“I told you. A boating trip.”

She fumed. “Fine. Be that way. Come here.” She dragged me into another room, some kind of office. The house looked even bigger from the inside; it was all very clean and neat, light hardwood floors, an open plan, a mix of pastels and birch that was almost hypnotizing. The office was less distracting, the walls not covered by bookshelves being instead covered by whiteboards. There was endless script on them, almost illegible, mostly shorthand for medical terms I guessed. She turned on her computer – a Mac, I almost sneered – and brought up some diagrams of the familiar X pattern that even I recognized as a chromosome.

“This is a generic sample I sent to the lab. My own blood, actually. It’s basically just normal DNA, so you know what it looks like.” She zoomed out, showing a whole bunch of little X patterns, mostly the same shape. Even back then, kids were shown electron microscope pictures of human DNA, so they had the general idea of what a chromosome looked like in the old species. I recognized it easily enough.

“Okay.” I knew what was coming, but I had to feign surprise. Maybe. It depended on how much she already had figured out… I was on edge.

“This is your DNA as of the time you visited the hospital.” She showed me another image, which at first was just a jumble of small lengths of… something, all of which were assembling into a single large circle.

“You sure?” The two images looked nothing alike.

“Ben, something was ripping apart all your DNA! You should be dead! This virus – which wasn’t built like anything I’d ever looked at – was getting into every cell, shredding your DNA up in record time, and then moving on, somehow without killing the host cell – at least, not immediately. I can’t make heads or tails of it. I tried submitting the lab results to the CDC for analysis, but they said it ‘isn’t a medical problem’. Like that makes any fucking sense! They were just saying they thought it was bullshit!”

I shrugged. “You have to admit they might be onto something. I mean, I’m obviously not dead.”

“This is serious!” She snapped at me and slapped a palm on the desk. I blinked and took a step back. I’d been still kind of caught up in how nice she looked right then, I had forgotten she was in work mode.

“Well, okay, but I’m just saying… clearly, you’re missing something here, since I’m alive.”

“I know.” She folded her arms. “But what I have is scary enough. This could be the most dangerous disease ever, Ben. It doesn’t focus on specific cell types, and even works on white blood cells. It doesn’t seem to have any vectors, but those can evolve quickly enough. It’s like it’s just being thorough and affecting every single cell in the body. There’s no possible immunity to it. If it picked up even slightly hostile symptoms, with absolutely no way to vaccinate against it… millions could die.”

I walked up behind her. I’d never been a Don Juan type, and until my encounter with 15226 changed me, I had always been incredibly timid around women. Still, in that moment I somehow felt a little bolder. I walked up behind her as she continued to stare intensely at the still-frame greyscale picture on the screen, and planted my hands on her shoulders. She looked up at me, and I innocently kept looking at the screen and started to give her a massage.

“What is this?”

“It’s me trying to get you to stop stressing out. Obviously, whatever it is, it isn’t as deadly as you think. And obviously, it’s not contagious, or it would have shown up in your own blood after you and I, uh…”

“Right… that.” She let out a breath. “I know… I just, I feel like I’ve got something here that could either be the worst thing possible, or the biggest discovery ever. But I’m a disgraced ER doctor who’s being investigated for sucking off one of her patients right there in the ward, so I’m not really being taken seriously.”

“I’m still sorry about that.”

“Forget it. I’m an adult. I made my decision… though, in hindsight, if I was so much more lonely than I realized, maybe I could have gone about seeking company in a better way.” She sighed, leaning back in the chair and letting me work on her shoulders. “I’m glad you seem okay, though.”

We were silent for a time. I became a little more insistent with the massage, digging my fingers deeper into her muscles and ineptly trying to work the tension out of her – but I was getting better at it quickly. Within a few minutes, she was leaning back with her eyes closed, purring. Whatever work she’d been doing was forgotten now and she was becoming increasingly relaxed.

“Let’s lie down for a bit. You need to take a break.”

“Fuck it… I guess so.” She let me guide her back out into the main room, where I flopped down onto the sofa and pulled her down to me. We arranged ourselves into a spoon position, with my chin behind her head and my nose just above her short hair. It smelled of shampoo, fresh; the roots were still wet. I guessed she’d gotten out of the shower recently and used a hair dryer. We laid there for a time while I continued to ‘massage’ her, using the excuse to explore her body with my hands in all the ways I didn’t get a chance to when we were in the hospital. The window opposite us in the room was huge, taking up half of the far wall, and looked out in the pine-tree forest lot behind us; she lived a good half-hour out of town, into the further suburbs. Except for a few other houses visible in slivers between the trees far away, the illusion of being in a forest house away from civilization was nearly complete. I liked it. I didn’t let my hands wander to too many places right then, instead sticking to her shoulders, calves, and after moving her a bit, her small feet. I ached to have her round tits in my hands, but I held off.

About ten minutes in, she abruptly sat up. Her face turned to mine quickly, and she looked astonished – like she’d just realized something. Puzzled, I didn’t respond, and she stood up and practically ran back into her office. I heard her tapping away at the keys furiously. I guessed she’d just put something together. Shrugging, I went into the kitchen and found the coffee machine, and started it up. Five minutes later, I had two mugs of the stuff ready for us. I realized I didn’t know how she preferred it.

“Ben.” She had stepped out of her office now, and was ambling back to the kitchen towards me – there was caution in her steps. She was almost tiptoeing, looking at me like I was a sleeping crocodile she had to sneak past. I knew then that she’d figured something out about me, something inexplicable by the mundane – just not what specifically.

“Bethany.” I gave her a little smile. “How do you take your coffee?”

“What are you, Ben?”

I wanted to laugh. Instead I just sighed. Even I wasn’t sure; how could I answer?

“I’m a very special kind of guy.” I shrugged. “One who wants to make you an even more special cup of coffee.”

She was quiet for a time. “Black is fine. Extra sugar.” I shrugged, and dumped a spoonful of sugar into the mug, and stirred it. I slid it across the counter. She slowly walked up to the bar stool opposite the counter and sat herself in it.

“What am I?” I looked down into the mug, swirling the coffee around. “Let’s hear your guess first.”

“You’re—“ Her voice caught. “You’re not human anymore, I can tell you that.” She swallowed after saying it, like speaking this revelation risked me beheading her on the spot or something.

“It’s not like that.” I took a swig of the coffee as I waved a hand. “I’m just another kind of human.”

“Looking at your genes, you’re something that didn’t even evolve from primates. It’s the same end result, but it’s a whole different way to build a person. It’s statistically impossible that a virus would just evolve to do that and nothing else.”

I snorted. “Sounds about right. Keep going.”

“Okay.” She frowned. “The reason you didn’t die was because the virus was reassembling your DNA after it broke into each cell. Normal viruses rewrite the cell just to produce more of themselves. Once I dropped that assumption, I was able to figure out that it was reassembling you, cell by cell, into a whole different kind of creature. Ben, there’s nothing like that on Earth. There never has been – ever. Nothing like that could happen naturally. Even the idea of medicine being able to produce something like that is barely even a theory. We’re at least a hundred years – fuck, two or three hundred – from being able to produce something like this that could work on bacteria or something – let alone people.”

“Well, it’s a good thing it wasn’t one of us making it then, huh?”

“What?”

“You’re basically right, Bethany. Since it’s you, I’ll just go ahead and tell you everything beforehand. A couple weeks ago—“

“Before what?”

“Huh?”

“You said ‘beforehand’. What are you going to do after you tell me?”

“I was going to give you a choice. If you say no, I’ll walk away and you’ll never have to see or hear from me again, and you can go back to doing whatever you want.”

“And the other choice is?”

“Do you just want to ruin the story or what? I’ll give you the other choice later. Drink your coffee and you get the story first.” Her eyes narrowed, and she took another sip, but her gaze never left me. She was looking at me like I might explode at any time. “A couple weeks ago, I got really sick. You know that much.”

“Right. The symptoms actually looked a lot like radiation damage, but the blood tests showed no radioactivity or heavy metal contamination, which was why we were so stumped. Then we figured it was maybe just a problem in the spinal column, possibly damage within the brain stem.” She frowned. “It wasn’t that either. They’re probably still scratching their heads back at the hospital lab.”

“Well, okay, we know it wasn’t any of those. What actually happened was that someone had just given me that virus, after they designed it to work specifically on me. It was rewriting everything about me to make me the first of another kind of human.”

“Okay…” She raised an eyebrow, not sounding sold.

“Hey, you asked. My symptoms began to clear up not long after you and I were – intimate – and I felt pretty good.”

“How’d you end up on boat in the ocean, then? Or was that bullshit?”

I groaned. “You’re pretty hard to tell stories to, you know that?”

“Sorry. Keep going.” She took another drink of coffee.

“I got back to my apartment after I left the hospital, and here is this… really weird chick, right there. She starts telling me all this crazy stuff, and she seems to already know about my, uhh, condition. I figure she’d nuts, or one of John’s new girlfriends. He seems to like them a little ‘off’. Anyway, I’m about to throw her out or call the cops – and she, uh, convinces me not to.” Bethany raised an eyebrow, but I didn’t elaborate. “Then, we’re suddenly at her place.”

“She has an apartment nearby? In your building?”

“It’s about eight thousand miles from here, actually, as the crow flies.” I paused, thinking. “That’s one hardcore crow.”

She put her coffee down. Even under the circumstances, my story was already leaving credulity behind. I was only getting started.

“So she, what, knocked you out and—“

“She teleported us.” I waved a hand. “Transported instantly, I mean—“

“I know what it means. Like on fucking Star Trek?”

“Kind of like that, yeah. Then she shows me around her place. It’s a big-assed underground base kind of thing, and she’s leaving soon.”

“Moving closer to the city?”

“Much further away, actually. She had an important date on the next planet in the sequence. She showed me her real self – she was a fucking huge spaceship. No crew, no entrances or exits, just a humungous piece of metal and engine, with her mind inside. She used to be something else… more like us. But she’s a spaceship now, and has been for ages. She was here to create an evolved version of humans that she believes can actually survive their own civilization.”

“Aaaannnnd… that’s you.” She pointed at me.

“I’m the first, and the only male of this generation. There were some technical reasons she couldn’t get into, that were why she could make only the one.”

“Leaving aside that this – you know what, fuck it. It fits the facts, so let’s run with it. But why create just one male? I’ve seen that DNA. There’s no way it’s compatible with normal humans. You couldn’t breed.”

“I’m a little more complicated than that. She could only make the one male, so she gave my body the ability to produce another version of that virus that works on any female.”

She got up off the chair, and started to back up. “Um… any?”

“It can’t be spread through the air, if that’s what you’re wondering. And I guess you can’t say you completely don’t believe me, if you’re afraid you might catch it.”

“How many have you, uhh, ‘infected’ so far?”

“Just one.”

“What are her symptoms? Does she need medical care?”

“She’s doing fine, actually. She’s been eating a lot, and sleeping otherwise, but the Experimenter – that was spaceship-girl who did this to me – she said that I could expect the change to take between a few days and a few weeks for each woman.”

“What are the vectors, if not by air?”

“Semen... just good old Ben’s semen.” I chuckled.

She peered at me. “I haven’t gotten sick. Am I immune?”

“You know, I asked her about that. She said I wasn’t finished developing the cells that produce the retrovirus at the time you and I first met. You wouldn’t have been infected.”

“Okay…” I’d expected her to be taken aback, but she seemed to just accept it. “How do you know it won’t just kill this other girl? This virus is incredibly powerful, Ben. I’ve seen it working inside you. One mutation in the virus and you’d literally fall apart. Your cells would break down, probably in only a few hours, and you’d die. It would be very painful and very, very ugly.”

“She apparently built in protections against that. You didn’t talk to this… being, you didn’t see what she was. She’s been engineering new versions of intelligent life for hundreds of thousands of years. She’s done this literally thousands of times. Also, I’m fairly sure if I will survive, this particular girl I already started changing will survive too.”

“Why? You’re not a virologist, Ben. Hell, you’re too young to be certified in anything. You can’t know that.”

“Well, she’s my sister, so if my DNA made it out okay, hers should too.”

“There’s not half as much sense to that as you thi—” She stopped. “Wait. You said it was transmitted through seminal fluid only.”

“I did.” I tried to hold back my grin as I thought of the other night. God damn, Emily was hot.

She was silent for a time. “I see.”

“We weren’t together before, if that’s what you were wondering. And it was consensual.”

“And she knew beforehand that you were going to infect her with a virus that would turn her into something inhuman?”

“A different kind of human. I’m still me. And, uhh, no, she didn’t know about that part… so you have me there. That’s going to be an awkward conversation.” I sighed. “I don’t have a good excuse. I just love my sister, and I want her to be with me in the future. Our future goes on for a long, long time, and I don’t really want to do this without her there to anchor me.”

Bethany’s expression remained calm and reserved for a time, but I could see her mind working hard behind those dark brown eyes. “I don’t entirely believe it, but I don’t have a simpler explanation…” She trailed off for a moment, then looked at me again with a slightly different, more intrigued expression. “I told you before that sexuality was my favorite subject, right? Cases of people… going outside it, always interest me. Professionally, I mean.” She seemed to be warming a little… I was glad she wasn’t looking at me like I would eat her anymore. “Tell me about your new humans. What’s the difference? Why throw out the entire genome, instead of just rewriting some key parts?”

“She said our DNA was full of useless garbage, and she wanted to optimize it. Something about really old viruses that managed to sneak into our DNA when we were all fish and monkeys.”

“That’s a pretty common theory… but we can’t know yet which sections are defunct viral code and which are critical sections that we just don’t understand yet.”

“She did know.” I shrugged. “Apparently it was part of her improvements to the immune system and preventing cancer. Less DNA to maintain meant the system could focus better on protecting the integrity of DNA, so we’re really unlikely to get cancer now. She left detailed notes, if you’re wondering… she actually told me directly that she wrote them for whatever doctors joined up with us, so we could be treated without having to start medical research over from scratch.”

“I’ll want to see those.”

“On one condition.”

“What? You want protection, or your secret kept, or something?”

“I do want my secret kept. But that’s a secondary condition. The condition is you become one of us too.”

Her eyes went wide. She dropped the mug, and the steaming liquid spilled onto her sweatpants. It took a half-second for her to register the pain, and she yelped. Hopping around on one foot, she fumbled around with trying to pull the pants off, hissing with pain as the stuff burned her leg. I grabbed some paper towels and rushed around the counter, holding her in place so she could stop hopping. I wiped off what I could of the coffee, and she held onto me as she pulled off the pants with her other hand. Her legs were short, like her, but shapely and a nice, rich tan color, like the rest of her. She seemed to have no qualms about showing herself to me; she was wearing only simple cotton panties beneath. Probably because she’d already sucked me off, but she seemed to not even think about it. She tossed the pants across the counter into the sink, then seemed to notice how close to me she was. She turned, and stared up into my eyes – not quite shying away from me, not looking scared all the same.

“It really wasn’t your fault in the hospital, by the way.”

“Uhh – what?”

“The Experimenter – she picked me, but she couldn’t risk me not learning my way around girls better. So she stuck this funny stuff in me; ‘pheromonal enhancement’. It basically makes my dick impossible to resist for any woman who feels even a tiny bit of interest.”

“Bullshit.”

“And yet, when you saw my package in the hospital, you couldn’t keep your hands off it.”

She peered at me. “I guess so. But it can’t be that difficult to resist. I mean, yeah, there’s no sense hiding that I’m a little worked up right now, but I’m in control of myself. People have been researching pheromones for decades. They aren’t that big a factor for humans.”

“Mmm… How worked up are you, exactly?” I pulled her a little closer to me, taking pains to let her feel my hard cock against her waist.

“That’s it under your pants, isn’t it…” Her hand brushed up and down, over the left leg of my pants where the outline of my rigid cock could be made out. It was straining to stand up, held back by my pants.

“That’s it.”

She snorted. “What’ll happen to me if I do this?” Her finger stroked up and down over the cloth, making me shiver. I wanted her bad now.

“Nothing at first. I was told the symptoms can vary between individuals. You might not feel anything at all, and just be different after a few weeks. You might get as sick as I was when you saw me before. Or something in between. When it’s done, your body will be better in every way, you pretty much won’t age, and there’s a bunch of other changes besides.”

She looked up at me, her eyes wide. “I won’t age? Just like that?”

“Yeah… so I’m told. I guess we’ll find out in ten or twenty years, huh? She said we can still be injured and all, but normal aging stops with adulthood with us.”

“Did this space chick ever think that you might find the girl of your dreams and just settle down instead of sleeping with every girl you see? And wouldn’t your kids all be related?”

“She was a lot more clever than that… but we can go over that whole thing later. I need you to decide now.”

“Oh… about that earlier? You would really leave right now if I said no?”

“If that’s what you want.”

Her fingers continued to stroke up and down over my meat. Her eyes were staring up at mine, looking mysterious; I’m sure she was wracking her brain, trying to weigh consequences. Her hand never left my shaft, though; I knew I had her.

“You really did that with your own sister as soon as you got back?”

“Her name is Emily. It wasn’t my original plan; it just sort of happened, but I don’t regret it.”

“I was an only child. My neighbors were my best friends growing up. Brother and sister, twins, Nathan and Natalie. The two of them got involved with each other when they were fifteen… they invited me to join them a lot of times until we were twenty and they left town. That was still the best sex I ever had. The only good sex, really… though giving you that blowjob was fun.” She smiled a little, then focused on me. “I’ll set one condition on my end, too, then.”

“What?”

“I want to watch you two together. Your sister and you, I mean.”

I raised an eyebrow, but had no objection. Emily might object, strongly in fact, but I figured she might see things differently soon. “Done.”

I suddenly picked her up with both arms, though I hadn’t realized I wasn’t as strong as I thought. Petite though she was, I could still barely carry her. I couldn’t wait for those damn growth spurts the Experimenter said were coming… and for the results of my new workout habit to start showing up. I’d seen a downstairs bedroom on the way in, which I carried her into as she wrapped her hands around the back of my neck. There was a knowing smile on her face as I walked with her in my arms, like she was looking forward to this. It was important to me, for reasons I didn’t yet understand, that I find at least one woman who consented to being changed into a hominus beforehand. It let me rationalize doing it to more girls without asking – but so far, I haven’t really had to deal with the issue of any of them coming to me and asking what the hell I was thinking.

“Is there some special way you have to fuck me?”

“Not really… if there is, I was never told.”

“Good… then me on top.” Biting her lower lip and smiling, she suddenly curled around me and before I knew it I was tumbling onto her bed. I found out later that day that she was big into judo, but for the time being, I only knew that somehow, this little woman I’d been carrying – who was a foot shorter than me and completely suspended in my arms – had found a way to throw me. I was still getting my bearings and trying to figure out what happened when she was straddling me and unbuttoning my shirt. She got down to the bottom and yanked it open, then ran her hands on my chest. My own hands wandered up her thighs onto the round globes of her ass – she was taut down there, firm and springy in a way that Emily hadn’t been. Emily just ran a lot to keep herself fit and skinny, but Bethany really worked out to make herself stronger.

My fingers sneaked under her waistband to happily find she wasn’t wearing panties – and as I did, she leaned downward, pressing herself to my bare chest. Face to face, she traced lazy patterns on my ribs as she laid atop me. “Is this what you meant when you said you’d make it up to me? I mean about losing my job, and everything.”

“I told you it wasn’t your fault.”

“If this is real… and I still don’t quite believe it… I’ll owe you everything.”

“Not really. I’m just some horny college kid she chose because she knew I wouldn’t be able to keep it in my pants… you can do whatever you want.”

“I’m already doing that.” Her hand had sneaked down below and was unzipping my pants. Drawing herself up, she pulled my dick out from my slacks, and I saw that same blissful look appear on her face. She stroked my meat a few times, then pulled my pants off completely. I was nude and she still hadn’t taken anything off. My hands became insistent, and she seemed to sense my intent and suddenly pulled her sweatshirt off, revealing a plain white bra. She unsnapped it just as quickly, freeing her breasts which I instantly grasped. They were warm, pliant, and firm, and her nipples were hard under my palms.

Her hand played up and down my shaft a few more times, then she looked up at me. “You were right… there is something funny about it. I can feel it in my thoughts… it’s like this thing is inside my head now, and I can’t stop until you come.”

“You can feel it?” The Experimenter said she’s made me ‘irresistible’, but hadn’t said how much the girls affected by it would know.

“Now that I know what to expect… it’s kind of fun, actually. God, I’m so much hotter than I’ve ever been around a man. The effect is so strong… I just want this thing inside me so much.”

“So take your fucking pants off and make it happen.” I yanked against them, showing the top of her bare waist. She pulled up one leg and sat on me while she pulled them off, and moments later I was presented with her nude body. Before I could roll atop her, she was back over me in a flash and rubbing her wet folds on the underside of my shaft.

She didn’t waste much time; I’d expected her to take it easy and slow for some reason. With a quick motion and a light touch on my shaft, suddenly I felt the head of my cock pressing her lips open and invading a warm, wet, soft place. Her expression became almost pained as she leaned down over me, her hair almost falling into my face as inch after inch sunk into her. She stopped me about halfway and rested – in what I guessed was an attempt to distract me from insisting on going all the way in right off the bat, she arched her back and presented her nipples. I tried to give them a little suckling, but my neck quickly became pained in the position I was in. I fell onto my back again, simply letting my hands explore her thighs and ass as she worked more of my meat into herself.

I have to admit, there is a certain primal satisfaction with watching a woman squirm and maneuver because your cock is just a sight too big for an easy fit. I just laid there and let her do the work, enjoying myself as she shifted and moved, grunting and groaning with the effort of stretching herself out so wide. Even my sister hadn’t been this tight – but then, she wasn’t as small as Bethany.

“Unnh…” She gasped. “I think I… have you in…”

I looked down. There were still at least two inches to go. I smiled at her. Time to take over. With a strong press from my hands on her ass, she gasped and gave a short yelp as I flattened her ass to my waist, sinking the last inches of my cock inside her. She almost fell forward on top of me, and after she caught her breath she gave me a light and playful slap.

“I wasn’t ready yet.”

“Only one way to get ready.” I gave my hips a little bounce.

“You’re fucking huge…” Her hand went to her pussy, splaying out flat against her mons. “It feels like a telephone pole got shoved in there.”

I snorted. “One big dick, courtesy of the space aliens.”

“Yeah, I’ll believe that when I see it.” She lifted herself up, and let her hips settle. Her hands went to the sides of my waist and gripped me, not hard enough to hurt – but firmly. I sensed her intent; she wanted me to stop and give her a moment to adjust. For that matter, I could use some time to adjust too – it was taking no small amount of control not to grab her and fuck the hell out of her.

“Well, I can’t show you the alien, she’s gone…” I slid my hands up her sides, feeling the contours of her figure. Her skin was softer than Emily’s, and she was slightly rounder – not fat at all, just not a lean runner-type like Emily was. “I can show you the secret underground base she gave me, though.”

Bethany raised an eyebrow. “You’re kidding. The same place she supposedly took you to? She just gave it to you?”

“You’ll just have to see for yourself someday.”

“This better not all be some fucking scam to get in my pants.”

“You’re the one who tested my DNA… and you’re not wearing any pants.”

She giggled, giving me another playful slap. As she shifted, she gave a long gasp as she felt my cock move a bit inside her. It seemed to be her cue, and from then on we didn’t speak; she gradually turned her inching motions up and down into a slow bounce. She pushed my hands off her twice as I tried to speed things up, but failed; she was insistent on controlling the pace, which I eventually just gave up and let her do, despite the protests from my aching balls which were boiling to fill her up with my stuff. The tight heat around my shaft wasn’t moving as I would like, but I found myself approaching the point of release anyway – perhaps it was the sight of her boobs bouncing in front of me, or the blissful look on her face as my shaft probed her more deeply than any man ever had before.

Her orgasm was so abrupt, I remember; it surprised me at the time as I heard her suddenly yelp and bend down over me, bouncing her hips while one hand diddled her clit. As she came, I could feel her muscles working around my cock, and I held her to me as she came down. She seemed to go limp after that, not quite unconscious but no longer insisting on being in charge. I rolled us over and came into a kneeling position, pulling her up to me with my cock still inside. Her legs and then her arms wrapped around behind me, and then my hands went to her waist and I lifted her slightly. It wasn’t easy, but it felt good to have her at my mercy like that – suspended, hanging off of me almost. My balls warned me they were going to explode, and I increased my pace, bouncing her up and down rapidly. Her arms tightened as her lower half bounced up and down, over and over again, my cock vanishing inside her repeatedly.

I groaned as the long-awaited orgasm came. Just like the sex we’d had, it seemed slow; coming lasted twice as long as it had before. I felt the pumping and the sensation as my head opened and spewed my seed inside her. It was done now. It had felt amazing, and I’d created another of my species… or would have, when her change completed.

We were both panting, and I waited until my cock went half-flaccid to pull out. She dragged me down onto the bed with her, both of us exhausted. I didn’t even take but a few minutes to go to sleep, staring into her restful face as she dozed off first.

I awoke a few hours later – it was still light out – to an awful sound. I waited a few moments, and then heard it again – this time even more awful. I pulled myself up and out of bed, and peered into the partially open bathroom door.

Yep, she was vomiting into the toilet. Beautiful.

I put my pants and shirt back on – no need to get my power going now, when she was feeling terrible – and went into the bathroom. She tried to wave me away and said I didn’t want to see her like this, but I didn’t care. It was my fault, regardless. It was immediately clear that her body hadn’t taken to the retrovirus well. She looked miserable already – her skin was pale, she was sweating all over, she was running a fever, her nose was running and she had a cough, everything. I wasn’t a doctor, but I might have mistaken it for a bad flu had I not known. She looked as bad off as I’d felt in the hospital. I helped her clean herself off and drew a bath for her, and with her laying on the couch, she provided me with some simple directions to where things were in her kitchen to make her some soup.

I carried her back into the bed after she’d gotten some food down. Surprisingly, she said she felt really hungry – even in her awful physical state, her doctor’s mind was working, and she knew that didn’t fit in with a simple flu.

Once she’d dozed off, I gave Emily a call. It rang a few times, before I heard it be picked up, and some muffled noises as she probably fumbled around for the phone which I’d left on her bedside table.

“You doing okay?”

“Uh… I don’t know… it’s weird… it’s like… have you ever… done five things, of tak… took… tequilas?” I hadn’t, but I could imagine. Emily sounded pretty well out of it. “Where did you go?... To the… store?”

“I had to a follow-up appointment with the doctor after the hospital visit a few weeks ago.”

“Oh… cool… did they say… anything? Are you okay?”

“I’m fine. All’s well. I’m more worried about you.”

“I’m… actually kind of… worried too.” Emily paused. I could tell she was trying to decide whether or not to tell me something. “Something’s… weird.”

“What?”

“I’m sick… I know I’m sick… but it’s like, I can see and hear stuff further away now… it’s kind of trippy, Ben.” She was quiet for a time. “The guy down the hall… he’s watching some porno… I’ve been, uh, listening to every word for the last hour… it’s kind of fucked up, though, because, uhh… he doesn’t have it up – loud or anything… am I nuts, Ben?”

“You’re not nuts. I actually think I know exactly what it is.”

“You do?”

“I do, but not now. Just get lots of rest, and any time you get hungry, order whatever you want from room service. I’m serious, go crazy and order three steaks a day if you’re hungry enough. I can afford it.”

“Like hell you can. I’m good enough… I think… to drag myself across the street to the mall… and raid the food court, every few hours. It’s about all I do other than sleep…”

I frowned, staring upwards as I tried to think of a way to convince her. The last thing I needed was for Emily to stuff her body with fast food and make herself even more unhealthy while the retrovirus ran amok with her body. Still, she really did sound like she was halfway to lucid over the phone, and I would be checking in on her as often as I could.

“Okay then, but if you feel worse at any time, let me know. I’ll be there right away.”

“Pfft. Yeah right… you just want to get your dick polished again… ‘Huh huh, suck some medicine from this tube, baby’.” She made a mocking over-masculine voice. I gave a short laugh. Well, she hadn’t completely lost it, anyway.

“All right, go to sleep before you get too nasty.”

“Okay...” We said our goodbyes and hung up.

I sighed, and hung my head low for a time as I thought through the day. My original plan had been to go to Emily and come clean to her too, but I just didn’t have the energy. I also feared that if I tried to have that conversation with her while she was sick as a dog, she and I both might think I was trying to take advantage of her weakened state. Always an expert at not dealing with problems, I decided I’d leave that whole thing for when she recovered.

I was really good at making bad decisions back then, wasn’t I?

After making sure Bethany was still sound asleep – deeper than that, even, I couldn’t even get more than a few unintelligible noises from her – I stepped outside and found myself walking back to my apartment.
