Unexpected Resurrection

Once, I was a man. I lived, loved, laughed, and died. I had no complaints with my life; there were more good years than bad. And I honestly wasn't sure whether that white tunnel was taking me to heaven or hell.

I was surprised when I woke up surrounded by large-headed slender gray beings. A voice in my head assured me that I wasn't going on to the afterlife just yet. I protested my resurrection; the cancerous mass in my chest was well beyond treatment, and I'd spent the last three months in gradually increasing agony. Death, when it came for me, had been a great relief.

It was then that I realized I hadn't felt any pain since waking up. I raised my head to look down at my body, and was surprised that my muscles responded immediately. My neck pivoted smoothly, and I observed that my body now bore little resemblance to the wasted, shriveled husk I'd previously inhabited.

My new body was nude, young and muscular. I clenched my fist experimentally, and turned my hand over to look at it. The skin on the back of my hand looked like it belonged to someone in his late 20s. To my left, there was a translucent 3D projection of my body, which was mirroring my movements. I put my hand to my head and noticed that I was completely bald.

One of the beings stepped forward, and words formed in my mind. "You are being sent back to Earth in a new body. Your mission is to adjust your species. Your body's abilities - and the genetically coded responses programmed into your species already - will make it easy."

I raised my eyebrow. "What exactly am I adjusting with this body?"

"You are the Progenitor of version 20", the gray being stated simply. And then it gestured at the projection of my body, and to my embarrassment its penis became erect. I looked back at the gray just as he touched some kind of control on my bed, and suddenly my vision was replaced with a wave of images cascading through my head. Many were intensely erotic, some appeared mathematical, and it just kept loading into my skull until I thought it was going to explode. Then it stopped, leaving my head feeling full of information which I might understand later on if I was lucky.

What I could gather right away, was that I wasn't even close to being the first human this had happened to. We think our species actually evolved, but it didn't. We're a specially devolved devolved version of the gray beings standing before me. The aliens' bodies were too fragile to survive on a freshly terraformed planet, so they developed us. We're the same species, just devolved to be hardier but with shorter lives. The aliens deposited our distant ancestors as cavemen on Earth tens of thousands of years ago, then let them breed and take over as the dominant lifeform. Each time our society reaches the necessary criteria for the next stage, they intercept one of our dying souls. That soul gets dumped into a more-evolved body with an upgraded metabolism, special pheromones, and various nanotech enhanced capabilities. If you're reading this, you are probably Human version 19, whereas my children are version 20. Version 20 humans are smarter, longer-lived, and don't become enfeebled as rapidly with age. We're the replacement for version 19, which was tougher and stronger, but with a weaker immune system and significantly more mental degradation during the aging process. The human evolutionary process has 32 steps, and the first children born to version 32 will look just like the aliens standing before me. There were thousands of colony worlds like ours, scattered throughout the universe and at different stages of development.

I started to open my mouth to say something, but the gray shook his head and waved. My eyes clamped shut reflexively as a brilliant flash of light washed over me, and then I was gone.

The Beach House

I heard seagulls overhead, and saw bright light through my eyelids. Opening my eyes, I could tell I was still lying on my back, but now instead of a dull white surface I saw a clean blue sky. And it felt like my butt was on fire. I sat up, brushing sand from my skin as I looked around. I saw that I was sitting buck-naked on a sandy beach, probably somewhere in California. Nearby, a small group of college kids were pointing at me and laughing. Thankfully, they seemed to have been the only ones who noticed me.

"Hey Rocky, you gonna stand there at half mast all day?" a female voice called out.

I looked down and noticed that my massive erection was still going. Blood rushed to my face in embarrassment, and I covered myself with my hands as I looked around for something to cover up with. The female voice belonged to a busty young blonde in a small bikini standing about 10 feet away on the sand, still dripping wet from coming out of the ocean. She was probably around 23, and her sharply defined tan lines showed that she rarely wore a bikini this revealing. It was like seeing again for the first time; I couldn't remember when my eyes could see this clearly. And bathing suits in the 1940s were a lot more padded than what she was wearing. Each drop of moisture sliding down her perfectly shaped breasts glistened, reflecting light as they made their way along. The thin, clinging top emphasized the outlines of her her perky nipples.

"I'm sorry, I don't know how I got here," I stammered.

The blonde smiled saucily and stooped for a moment to pick up a towel, then kept coming towards me. She offered the towel to me with her outstretched hand and said, "Then you might want to cut back on the booze, buddy. Waking up naked is only awesome if you can remember why you're naked."

I took the towel and thanked her, wrapping it around my waist. The embarrassing bulge still persisted, but at least it was covered. "Think you can remember my name if I tell it to you?" she asked, smiling impishly and stepping up to me. She was almost close enough to kiss.

Now that I could see her up close, I knew she'd be impossible to forget. I could smell the faint odor of the ocean on her, mingled with suntan lotion and the dusky remnants of some perfume from last night. "Just try me."

"Kimberly Donovan," she purred, tracing her finger down the center of my chest. I started to wonder if I was dreaming, because even when I was young, women never came on to me like this. Some of her friends gave each other odd looks as Kim wrapped her arms around my waist.

She let out a little hum, leaning in to smell my neck. Where her skin touched mine, it felt like an electric field. My penis was made of molten steel at this point, quivering with anticipation. She brought up her mouth and assaulted my lips, drawing herself to her tiptoes and kissing me. She started questioningly and exploratory, then with increasing passion. Still a bit surprised, I wrapped my arms around her lower back and returned the kiss, putting myself into it too. I could feel her body molding itself to me, and then something else entered my awareness: her friends. I opened my eyes and looked up as one of the guys she was with approached us.

I pulled back and Kimberly pouted for a split second, as if a spell was broken. Her friend asked if she was all right, his eyes narrowing a bit as he scrutinized her reaction.

"Yeah, I'm fine. I actually just realized I met this guy here last year and we really hit it off," Kimberly lied.

Her friend raised his eyebrow. "Well, he's welcome to hang out with us if he wants to," he offered.

Kimberly gave a mischievous half-smile. "Thanks John, but I'm just gonna help him sober up and get some clothes on. I'll call before dinner though, ok?"

John looked back at me, clearly concerned for Kimberly. "I think one of us should go along."

Kimberly shook her head. "Nah, you guys enjoy the beach. I'll keep my phone on me and you've all got me on your finder apps, so it's not like you'll have a hard time keeping track of me."

John was clearly unhappy. "Kim, you don't know this guy. Even if you did meet him last year, you don't know what he's been up to lately."

Kim rolled her eyes and an edge crept into her voice. "Dammit John, I'm going to do what I want. Your brother and I broke up last month, and he's already dating Jackie anyway. So quit trying to look out for his interests."

John sighed in defeat and turned around, starting back to his group. Halfway there, he turned back and said to me, "You make sure she calls us if you go anywhere else. My dad's with the sheriff's department." He pulled a cellphone out of the pocket of his shorts and held it up for a second before saying, "And I've got a picture of you now too. So if she's in any danger..."

I interrupted him with, " ... then you've got a picture of the guy who will have saved her from it. Relax, I'm not going to hurt her. Where I was raised, a man doesn't hurt women."

John waved dismissively, not wanting to speak further. Clearly, he was reserving his opinion on what would actually be safer for Kimberly, but knew she'd do what she wanted anyway. I certainly agreed with his concern, for that matter. However, my hormones were getting the better of me and Kim seemed to be thinking the same way I was.

"John gets a little protective of me, ever since I was dating his brother. He's sweet, though." She pulled me a little closer. "Now, where were we... ?" she asked.

"I think you were going to take me to a hotel to get cleaned up and sorted out? I don't even know how I got here."

Kim raised an eyebrow. "Yeah, our beach house is over this way. C'mon, follow me." She held my hand and led me towards the sidewalk. I found the sensation of the hot beach sand on my feet and toes painful but pleasant. Honestly, feeling anything below my knees was a pleasure after years of diminished circulation. I welcomed every scorching grain of sand, savoring the way it shifted between my toes. When we stepped onto the cement, I treasured each step of texture I could feel in the sidewalk. And then there was the view. I'd forgotten what it was like to be on a busy beach in the summer, as women paraded by displaying their tan bosoms to the world. I couldn't help but notice, and almost every woman under 50 was returning my attention.

Kim stepped up to one of the many beach houses rented out to college students for spring break, then reached into her bikini and pulled out an artfully concealed key. As her hand snaked back out with its prize, I caught the briefest tantalizing flash of a nipple. She released the lock and pushed the door open, stepping through and saying, "Now, I hope you don't think I'm easy, or that I do this often..."

I stepped inside with her and drank in the view. It was a well-furnished and functional abode, clearly set up for temporary living. "Do what often?" I asked.

"This!" she nearly growled. She yanked the towel away from me, nearly taking me off my feet. I turned around and caught a feral look in her eye, intense and focused. My hard-on sprang back to furious life, just waiting for her body. I barely had time to face her before she jumped into my arms, wrapping her legs around me like a spider monkey and kissing me as if she were drowning and I were her only source of air. I returned the passion, wrapping my own arms around her waist as I felt her shift her body lower. Her bikini bottoms were rubbing against the tip of my penis, the simultaneously smooth and rough texture of synthetic fabric. They were still damp from the ocean, but from what I felt through them I knew they'd be dampening further in a matter of moments. I moved my right hand to her lower back and squeezed, thrusting at her as she ground against me. I could feel the tip of my penis pressing against her bottoms again and again. There was a growing wetness where my penis was grinding against her, dipping slightly into her vaginal opening and pulling the fabric in with it. She moaned with anticipation and ground back against me, pulling her pussy towards me. There was a damp noise as she thrust, a quarter inch or so of my penis inside of her but still with the bottoms in the way. Kimberly let exhaled sharply and ground her breasts against me, yearning for even more skin contact.

"Where's your room?" I asked. She pointed towards a door at the top of the stairs, and I carried her upstairs. She was still wrapped around me, trying to get my penis to drill right through her bottoms. I was probably three quarters of an inch in when she reached behind her and pulled at her bottoms, shifting the cloth a precious inch or so. I could feel the fabric pull away from between us, and then gravity took care what came next. She let out a gasp as I slid deep inside of her, with her legs still wrapped around me and us walking up the stairs.

I took a few steps and then stopped, pressing her up against the wall outside her bedroom as I buried myself in her. She pulled in a sharp inhalation as I thrust hard, with her back against the wall, burying myself as far inside of her pussy as I could go. I could feel her wetness enclosing me completely, and part of me just wanted to finish fucking her right here. My right arm was wrapped around her waist, holding her precious body right where it needed to be, but my left fumbled around until it found the doorknob to her bedroom. I had to do it blind because Kim was kissing me intensely as she gripped my torso, exploring every inch of my mouth. The door gave way with a creak, and I wrapped my left arm back around her perfectly shaped butt and lifted. We were back to fuck-walking again, her body bobbing up and down on my shaft with every step. I could feel her tightening around my pole, her breathing becoming ragged. I clutched her tightly as she let out the first of a series of little gasps, working up higher and higher in pitch and volume as she ground her hips on me. I felt her pussy clench as she came, setting her teeth and trying not to scream in my ear as her diamond-hard nipples bored into my chest from the tightness of our embrace. The panting slowly subsided as I located the bed, then turned around and fell onto it, with Kim on top. As we hit the bed, she gasped as our impact drove my shaft even farther inside her. She untangled her arms and legs from me, sitting up on all fours, but with my cock still firmly inside her now-soaked pussy.

The first thing she did was tear frantically at her top - she fumbled at the front clasp as if it were on fire, then let out a little scream of frustration as her trembling hands failed. She just grabbed it and yanked upwards, unholstering her magnificent natural 36" breasts as she pulled off her top and flung it at the window in a single fluid motion.

I brought my arms up and wrapped them around her waist, thrusting gently at her and exploring her in a more leisurely way than I could when she was wrapped around me. My hands found the bikini bottoms and quickly burrowed beneath them, cradling her ass. Kim looked down for a second, then fumbled with the knot at the side for a few seconds before successfully untying it and working on the other side. I craned my neck upwards and saw her pull the panties out behind her, then throw them in the same direction as her top. Now completely naked, Kim ground her pussy against my cock and commanded, "FUCK ME!", thrusting to enunciate both words.

No part of me could even begin to think of a reason not to obey her. I thrust back, lifting her in the air and burying my 7" pole all the way into her throbbing sex. She let out a shriek of pleasure as I ground back against her, taking me as far inside of her as she could. I drew back and thrust again, clutching her firmly as her arms and legs coiled around me like steel cables. She was python and tiger combined, scratching at my back as she wrapped herself around me, desperate to keep me in her grip. I gasped for air as the heat between us rose and we started to sweat, moisture sealing us to each other like a single being struggling to achieve nirvana. She ground herself into me determinedly and kissed me with her tongue, and when I looked into her eyes I could see nothing but pure, unbridled desire. As our eyes met, I felt a fire kindle in me, quickly moving down below my waistline. I closed my eyes for a moment, feeling my orgasm building. I returned the kiss as power built up inside of me. From what I could remember of my last life's sexual exploits, the pre-orgasm I was having now had already beaten the best orgasm I'd had in my life. A small part of me was freaking out because I was having completely unprotected sex with a woman I'd just met, but that part was small and irrelevant. The only thing that mattered to me now was to finish, to cum inside this woman and fill her body with my seed.

Suddenly Kim blinked and froze up. "Wait a - what the hell?" she shrieked. I was startled, looking into her panicked face with my penis still inside of her, my climax still building. Her hips were frozen in mid-thrust, and her brain was apparently still processing the fact she was busy fucking some man she'd just met.

"Let me go! Get out of me!", she yelled. Her arms and legs were intertwined with mine, making it difficult to disengage. I loosened up a little, but my penis was still inside her, and I could still feel it tightening as my climax built. The orgasm was about to be the best one I'd ever had.

In an impressive feat of strength for her size, Kim pressed at my shoulders, lifting my torso up off of her and looking down to where she could see my penis protruding from within her hot, slick pussy. "Pull OUT!", she demanded.

I couldn't do it. My hands clenched around her firm buttocks, trapping her as I thrust upwards with grim determination. My penis shuddered, fully penetrating her as she pushed at me. Her own body betrayed her as I bottomed out, triggering her own orgasm. Her vagina convulsed as she came again, and as the sensations ripped through her nervous system she changed her mind again. She wrapped her arms around me again and pulled hard, crushing me to her as the first blast of my sperm blasted at her so hard that it felt like it'd blow a hole through her. "GOD!", she screamed out as she felt a jet of my cum strike her cervix, and then another and another. Her orgasm was still going, fueled by my continuing ejaculation, which in turn was being prolonged by the vaginal contractions of her pleasure. We were somewhere else entirely, inhabiting a plane of mutual erotic bliss as we clutched each other. I felt fluids beginning to seep out around my penis, even as I filled her with even more of my sperm. I pulsed again and again, slowly draining the last of my semen into this girl I'd just met. Kim's breathing slowed and normalized as she loosened her death grip, just holding onto me contentedly. Still on top of me, Kim shifted her weight a little and lifted herself up a little, then ran her hands down her body. She paused on her belly and looked down at it, then almost timidly ran her fingers down until she touched her soaking-wet pussy. A finger experimentally poked down further, touching my shaft and confirming that I was actually still inside her.

"Oh shit", she said, "you did NOT just do that!"

She pulled herself off of me with a wet sucking noise, letting our commingled sexual fluids pour out of her vagina. She rolled off of me, flopping down next to me and letting out a disbelieving sigh. I rolled onto my side and faced her before saying, "I'm sorry, I just couldn't let go. You were so passionate until the very end..."

Lying on her side, Kim raised one of her legs a little, and I watched as a steady stream of white fluid flowed out of her vagina. "I was, wasn't I? If I think back, I remember it just fine - but it's almost like I was someone else, right until the very end."

I raised an eyebrow. "I give you my word, I didn't give you any dr" - I began.

"No", she interrupted, "I know you didn't drug me. Hell, you were stark naked when I saw you on the beach, you didn't have anything on you. In fact, you just appeared out of no where, right where I was looking. One moment there was just air where you were, and the next moment I saw a man I had to fuck, even if I had to rape him. I don't blame you." She ran a finger down to her pussy, and wrinkled her nose as she saw it covered in my white goo. "Well, not much, at least."

Kim took a deep breath, closed her eyes, and ran her finger back down to her pussy.

"Kim?", I asked as she inserted her finger and started to slide it back and forth inside of her.

The only response was a moan - apparently normal-Kim was gone again, and the frantic fuckbunny Kim was back in charge. I watched as she began rubbing her clitoris with one hand and scooping at the sperm that'd run out of her, then trying to stuff it back into her pussy. She rolled onto her back and spread her legs wide, raising her ass a few inches off the bed for a better angle as she entered herself with sperm-covered fingers. It wasn't long before I heard moans of pleasure from her again, with a rapture on her face only barely exceeded right before the end of our frantic lovemaking session. I propped myself up on my side to enjoy the show, as well as to wonder what kind of strange life I'd been reborn into.

Kim had her hips thrust upwards, and she was deep in the throes of her third orgasm when she suddenly froze in place with her fingers deep within herself. Her eyes went wide open, an expression of horror on her face as she realized she'd lost control again.

"What - the - FUCK?" she called out as she let her ass go back to the bed. It seemed an appropriate expression, expressing both the general situation and her shock at it.

"That was an interesting episode", I observed.

She shook her head in amazement, wiping her hand on the bed sheet. "I have no idea what's gotten into me today. This really isn't like anything I've ever done."

I shrugged. "If it's any consolation, neither have I." I was finding the afterglow of sex to be somewhat of a relief; for a moment, I didn't feel the overwhelming urge to mate with Kim I'd felt up until I came.

Kim furrowed her eyebrows and brought her hand up to her navel for a moment. "What's going on?" I asked.

She scooted up in the bed so that she was half-sitting up against the headboard, then said, "I guess all that sex must've upset my stomach a little."

"Wouldn't surprise me," I replied.

Suddenly she bent forward a little, probing intently at her navel with a concerned look on her face.

"Are you ok, Kim?" I asked.

"Not exactly", she replied. She sat back in the bed and took her hand off her belly, revealing that what had once been firm and flat was now distinctly beginning to bulge outwards from a point just below her navel.

I looked in surprise as the bulge slowly increased in size. I thought back to my experience with the grays. "Oh, shit, I think I saw this movie a while back."

Kim locked her eyes on me, terrified and begging, pleading for me to at least explain what I had just done to her. I looked from her eyes, to her expanding belly, and back. Some small stretch marks formed as her belly continued to distend. I reached over and put my hand on her belly, feeling as it expanded inexorably. She looked like she was about three months along now, still growing. Her belly was firm and full, but the rate of growth was slowing. The fear and anguish on Kimberly's face diminished somewhat as her belly stopped expanding. If I had to guess, I would've guessed she looked around six months pregnant.

Her expression changed to accusation and disbelief. "What, exactly, is THIS?" she demanded, pointing at her now-swollen belly.

I sighed. "Honestly, I'm not even sure. All I know is that it has to do with the next stage of human evolution."

Kim struggled to sit up, finding it nearly impossible with the new center of balance she'd acquired over the course of the last few minutes. "Human evolution, huh? What part of human evolution is supposed to get me - ohhh!"

Kim's mouth opened in pain and her hand flew underneath her bulging belly. She jerked as if she'd had an electric shock, breathing roughly for a few moments. "Contraction, I think," she said grimly.

I looked down at her vulva, which was still dripping with my cum. I dabbed at it with the bedsheet to clear it off, trying to get a look. "Maybe it wasn't?", she said hopefully.

Then she took a gasping breath and gritted her teeth as her belly flexed with tension. Her face contorted as she clamped down, the pain playing across her face as the contraction built up to its crescendo. She started panting with exertion just before I heard an audible pop, and her vulva began to leak a clear fluid. "Looks like you were right, Kim" I said, still amazed at what I was seeing.
