It is a cool and foggy night in a deep wilderness. Hours ago, while you were still hiking, the sky suddenly glowed eerily, and a deep rumble was let out of the earth. You were anxious, but miles and miles from help, so you continued on the trail, and eventually made camp. Now you're sound asleep in your tent, having eaten heartily, when a sleek black dart, a leech-like little thing, silently chews a hole in the fabric. It squirms into your sleeping bag and then into you. The next morning you feel well-rested. You pack up and continue your voyage, unaware of your new passenger. In a week, you're back in the city, relaxing comfortably in your apartment on the last day of your vacation. You pour your favourite drink. All is well.

Five months have passed. You've been back at work at your office job, lazing the day away and getting paid a pretty penny before returning to your home and relaxing. You're very responsible. You wake up at seven AM every weekday to get ready for the commute. But this particular morning, you awake with a painful erection. You think nothing of it. You're a man, this is no novel phenomenon. You brush your teeth, you get dressed, make yourself some coffee. It's been twenty minutes now but your little guy isn't taking a hint. Too bad. You're not going to be late for work because of him. You take the elevator and get to your car and begin your commute but it's getting harder. You can feel your heartbeat through your thigh. Your mind is flooded with your favourite sexual fantasies as you get off the on-ramp. You feel like your brain is going to explode if you don't cum right this second. You pull into the shoulder and begrudgingly whip out your cock. He looks red and angry, a prominent vein bulging where you've not noticed one before. You get to work. It isn't long before you climax into one of the wet wipes you keep in your glove compartment. You toss the tissue out the window and merge back into traffic. Ridiculous. You're five minutes late for work.

The next morning, you awake with the same painful erection. You manage to ignore it through your whole morning, and your commute! While walking up the stairs to your fourth-floor cubicle, though, the friction of your dress pants across your titanium member is too much to bear. Your knees buckle on the third flight of stairs and you feel the pleasurable full-body pulse of orgasm. A coworker rushes to your aid. Embarrassed, you assure them you're fine, you're okay, you just stumbled. You go to the bathroom to clean yourself up, before getting to work. When you get home, you set your alarm early, for some spare time. That is your compromise.

Your libido, however, proves relentless. Your pants tighten whenever any woman walks in front of you. Lurid daydreams cause you to trail off in the middle of sentences. You envision yourself bent over your boss's secretary, fucking her raw, and watching her belly become gravid over the course of the next few months. You find yourself taking daily bathroom breaks and, during lunch hour, you sit in your car playing with a recently procured fleshlight. You're masturbating three or four times a day and your balls still ache from... fullness? You come to the realisation that what you need is a woman's touch. So you download tinder.

You're a charming man. You can get sex if you want it, and you really want it. After a volley of flings and one-night stands over the next few months, your desires begin to simmer. You experience a return to normalcy. Ahhh, you sigh, you pump a sexy lady once a week, and everything wrong is right again.

Something else, though. You've been much hungrier for a couple months. It's been just impossible to stick to your meal plan. You find yourself picking up larger and larger orders of fast food, and just pigging out. You start going to the gym more to compensate, which is a bonus, because you get to make talk with hotties and stare at their fat asses and dream of knocking them all up. But you still grow a little belly, a fine curve around your toned thighs, your core, your arms. This distresses you a little, but your next few hook-ups assure you they like how you look. Life goes on.

It's another few months before you notice something of high strangeness. From what you can tell, your penis has gotten... larger. It was never small, a respectable 5 1/2 inches, according to your last girlfriend. Now, though, now it was truly something to behold. Thinking about it, you can feel its weight. It's girthier. Longer, maybe ten inches. Veinier. The urethra is so prominent while you're erect. And your balls are a little larger too. You can't make any sense of it, but you're still inexplicably proud. Perhaps an ultra-late growth spurt, you consider, as you begin to play with your newly noticed toy. You leak pre-cum readily upon mere manual stimulation. It doesn't take long at all. A powerful orgasm overrides your nervous system, and you shake like you're in an electric chair of pleasure.

A few days later, on a slow afternoon, one of the interns, Amy, says something to you. "Have you gotten taller?" And you think she's flirting with you at first, because you're a libidinous bastard, so you flirt back, but she looks a little disgusted, and she says, "No, really, have you gotten taller?" You apologise, you say "I don't think so." But when you get home you get a tape measure. You were definitely not past 6' before. You weren't even 5'8". You think, what is happening? You think, I need to go to a doctor. But an inner voice tells you, Don't look a gift horse in the mouth. You're a stud, now. A thick, tall stud with a massive cock. You're getting more attention than you've ever had, even from men, which you aren't unappreciative of. Why question it?

Another couple weeks. You've hooked up with a woman named Charlisse. You're in her apartment, and you're splitting her asshole apart, and as you climax, you feel something solid and slender slither up your urethra and escape. Charlisse felt it too. "What the fuck was that?" You say nothing. You dress, leave the apartment, and you ghost her. You're terrified just thinking about it. Something's inside of you. Something's inside of you and it's using you to get to others. But your voice of reason breaks through. This isn't a horror movie. You're fine. But no, that can't just be it, you felt it. Did you? Maybe it was just a thick load. That happens with age, you know. But that doesn't sit right with you.

You avoid intercourse for the next few weeks. You delete tinder and you go back to masturbating, which feels nice, but fails to satisfy a deep itch. The truth is, you'd gotten very used to having sex two or three times a week, and now that you've gone cold turkey, the previous symptoms have come back tenfold. You find yourself genuinely planning to sexually assault Amy, absent-mindedly, as though it would be no big deal to rape her and leave them in the breakroom leaking your cum. You redownload tinder on company wi-fi to find a date for that very night, but no luck. You leave work two hours early. Feeling sick.

You drive around later that night, looking for a prostitute. You find one. She's in her late 40s, but she has huge tits. You rail her in your car. You tell her how badly you want to knock her up. She screams for you as you cum, and that's when you feel it again. A tickle in your piss-hole. You drive your cock deeper, and collapse on top of her. More follow the feeling, little things crawling and escaping. She starts trying to get away, struggling, but you hold her in place and suckle on her nipples. Eventually you release her. She scrambles out of the car. The mind-fog clears, and you go home, with paradoxical feelings of mortal terror and existential satisfaction.

You take the rest of your vacation days, three weeks, saying you've injured yourself and need bed rest. You don't leave your house, instead spending every day just masturbating. It's normal ejaculate, every time. But your testicles swell up to big, beautiful walnuts that hang oh so virilely, and you swear you can feel them squirm. And the worst part. That inner voice telling you its nothing. Telling you to get out again, to ~~spread your gift~~ fuck some pussy, have a good time, let loose.

Eventually, you have to go to work again. You're afraid of going to the doctor to get a more long-term leave. You brave the office. All goes well. Another return to normalcy, maybe!. This is workable. But you start getting hazy during work. Your mind clouds up, and you can't think, and then, maybe, thirty minutes pass before you're back to normal. You drink more coffee, and then you start taking caffeine pills and then adderall you get from your sister but it doesn't help. And then, one day, you black out, and you're railing an intern in a broom closet. He's crying. You're choking him. You climax. It feels so good to let them out at last.

You never go to work again.

It's constantly swollen now. And it's so much larger. It's always slick with a slightly gelatinous layer of pre-cum that oozes out like a faucet of slime. You bottom out every vagina you stick it in. That's okay though. It's easier to use grindr anyway. No more first dates. Everybody you stick it in says it hurts. That you're so big. Some are into it. Some aren't. You don't care. Once it's in, they will receive your gift, whether they like it or not.

You see them sometimes, if you pull out too quickly. Leech-like little things. They hate bright lights and love warmth. Your children.

You sit and fuck all day yet you're getting so strong. You can feel the power behind your legs, your arms, your core every time you thrust, every time you need to hold someone down. Your abdomen is grossly distended. Your penis is deforming. It's becoming cherry red, slickening, tapering off to a point, with a closed urethral sphincter that dilates pleasurably when your children come through it. Your testicles hang, big as softballs, your scrotum swimming with small bodies. You can't let people see it before you stick it in them. Eventually, you can't get anyone at all. They back out at the sight of you, or maybe the smell. Something's wrong with you. You can't even get escorts to have sex with you. You're becoming something else.

You only go out at night. You prowl the streets. Prostitutes, homeless people, drunkards, anybody, male or female. You fill them up. Eventually you start chasing people down alleys, cornering them, quickly, expertly sticking your member in, letting it fill them, before sprinting away. You slip it in surreptitiously on dance floors. They scream, and you disappear into the crowd.

How long have you been this thing? Months? Years? Moments of lucidity terrorize you, before returning to psychotic sex-filled fervour. Breed. Breed.

You're evicted. You're homeless. You're not eating as much as you should. You try drinking from your tap, but your entire body glows with pain and you scream, a terrifying self-defence mechanism. So sometimes you eat your prey.

Then one day, you wake up, and you can think straight again, finally. You need help. But who to go to? You'd probably be experimented on by the CIA if you went to a doctor. You'd be gunned down by the police. You realise your only option is family. Your sister. You have to find your sister.

One late, stormy night, you knock on her door. She answers, horrified. Is that you? All you can do is **pounce~**

Consciousness breaks back through. You're not in control of your body anymore. You're on a bed, bent over your lovely, ravishing younger sister. The feeling is unimaginable. Your monstrous penis melts into her. She's screaming so loudly. Tears and snot stream down her face as you mechanically push into her slit. Her husband lies dead next to you two, a permanent grimace, and a cut throat. An alien thought pushes into your mind.

"T̷h̴a̸n̴k̷ ̵y̵o̷u̸.̸ ̴Y̸o̸u̵ ̸w̶e̸r̵e̸ ̸t̷h̴e̵ ̸p̷e̵r̶f̴e̵c̷t̷ ̴h̶o̴s̵t̶.̵"

You die, as your brain, the last vestige of your consciousness, is obliterated. The head of your living corpse explodes with gore. A wretched leech mouth rises out of your torso. Her mouth is wide open, but your corpse is deaf. Still thrusting, your corpse falls over her. It sucks her head into its mouth. Its torso splits open and thick black gelatinous tentacles pour out. She finally stops moving. The combined biomass, sufficiently genetically compatible, will be used to create the new god-queen of this planet. Across the city, the same thing is happening. A web of sexual interaction with you as its vile epicentre. Mothers, fathers, brothers, daughters become one. The next generation.
