walking through the forest near your house has always been calming for you. the peaceful quietness of the forest after dark is something you longed for all day. today was no different. a long day at work had you heading for the forest as soon as you got home. you gathered your flashlight, blanket and a sweater and locked your car. leaves crunched under your shoes as you disappeared deeper into the thicket.

the light of day disappeared quickly as you wandered deeper and deeper. by the time you found a spot to lay your blanket, the stars were starting to appear. you placed your fluffy blanket down on the ground softly, laying down to watch more stars litter the sky. this activity was something that had begun to be advised against. the discovery of aliens had made most people scared to be outdoors for long periods of time.

you, however, were in denial about this supposed alien life that had been discovered. it felt like weird timing that you couldn’t put your finger on. therefore until you saw one with your own eyes, you wouldn’t believe anything about the aliens. the stars sparkle in the sky as the sky reaches its darkest state. you ponder on the extraterrestrial life that has finally shown itself. would they ever really invade earth? you wondered how the world would react to this kind of attack.

you shake your head. the aliens aren’t real, there’s no invasion to worry about. the government just wants to make up a distraction for some scandal. you raise your arms to rest them under your head, admiring the beautiful sky. your eyes lock onto a star that seems much brighter than the rest of them. but not in a ‘northern star’ way, but in an unnatural way. you rise and sit cross legged, tilting your head in confusion. it almost seems like it’s getting bigger or, like, approaching you.

you stand up and stare up at the light. you realize that it is, in fact, approaching you. the light gets bigger and bigger until a beam of light appears in a circle on the ground. it seems like the light is searching for something. you stand in place like a deer in headlights before deciding to get out of there. you leave all of your things where they were and start running. your quick movements seem to have alerted the light and it starts chasing after you. you run as fast as you possibly can, your legs working overtime. your foot catches on a branch and you come tumbling down onto the ground.

the light settles onto you, the harsh wind from some kind of aircraft sending leaves and twigs flying. before you know it, your body is being lifted off the ground. you thrash around, trying to escape. before you know it, you’re reaching the source of the bright light. you see some sort of door open before you lose consciousness.

____________________________________

you come to, the lights of a bright, white room blinding you. you squint, adjusting to your surroundings. your eyes struggle with the lights, the room feeling ten times brighter with the harsh fluorescents. your eyes settle on a dark figure in the corner of the room. the figure seems skittish, avoiding your gaze. “hello?” you say, your voice breaking. it feels like you had been screaming, but you have no memory of anything since being lifted into the air.

your eyes adjust to see what looks like a person in the corner. you can see the person fiddling with their hands. “h-hello, human,” he responds. he sounds like he has some weird accent that you can’t place. he wanders closer to you, and you can finally get a better look at him. you know immediately that this is one of the aliens you were so in denial about. his arms up to his elbows are a dark purple and so is his nose and the tips of his ears. it’s a beautiful shade but also very inhuman. he also has a third eye sitting in the middle of his forehead, between his other two eyes. his inner arms up to his shoulders were adorned with small suction cups like an octopus. other than his obviously alien-like features, he looks relatively human. he has a pretty, dark wolf cut and two of his eyes are brown, despite his third one being a bright yellow. he has pretty, pink lips and flushed cheeks. he looks so nervous to be near you, despite being the one who abducted you.

you try and get up out of the chair you’re in and find your legs to be strapped down, along with your wrists. “please, stay calm, don’t fight the restraints,” he speaks again, his eyes darting all over the room. anywhere but you. “why are you doing this? please, let me go. i won’t tell anyone about this,” you plead, worried your life is in the hands of this being. “i’m not g-going to kill you,” he explains. he almost seems more scared than you are. “i need your help.” you furrow your brows, confused. “for what?” you ask, tugging on your restraints again. “my people… they’re going extinct. there are no females left on my planet,” he trails off, his eyes staying glued to the floor. “i chose you to help me with… repopulation.”

your eyes widen so much that you’re worried they might pop out of your head. “repopulation!? no, no, no, i can’t help you with that,” you smile awkwardly, not knowing how to even react to this information. “i’m human and you’re… what are you? and who are you?” you ask, looking him up and down. “i’m beomgyu and i’m from venus. i’m a verenok,” he explains, as if it was nothing to you. as if you would understand. “okay, my point still stands. i’m a human and you’re an alien. how am i supposed to repopulate your planet if we’re of different species’?” you do your best to gesture at yourself, despite beomgyu not even looking in your direction.

“w-we don’t have to be the same species. i just have to… uh…” he trails off and scratches the back of his neck nervously. “you have to what?” you ask, worry filling your tone of voice. “i have to knot you,” he blurts out. you look at him, confused. you had no idea what that meant but you can only assume it’s some sort of mating thing. when he scans your facial expressions, he panics and adds more to his statement. “it’ll feel so good, i promise. i have this pill to give you that will prepare you. it’s an aphrodisiac,” he reaches into the pocket of his pants and holds up a medium sized pink pill. before you can respond, he walks over to you and forces your mouth open. he drops the pill down your throat, followed by a syringe of water that seemingly came from the same pocket.

he looks at you with guilty eyes, seeming to immediately regret his decision. “i’m sorry. i just really, really need your cooperation. i’ll be back in a bit once the pill starts working to see how you feel,” he explains before scurrying away and out the door. you open your mouth to call out to him, but it’s too late. you settle into your spot on the examination table you were currently strapped to. an aphrodisiac? did he seriously just force a sex drug down your throat? all you could really do was wait, either for him to come back or for the meds to kick in.

much to your dismay, the meds kick in long before beomgyu returns. you’re writhing on the table, your whole body burning. you clench your thighs together, desperate for any form of friction. you sweat profusely, your clothes sticking to your body disgustingly. “beomgyuuu,” you call out for him, you body basically begging for the man who had previously promised you sex. you begin to border on crying, your core so desperate to be touched. “gyu, please come back, i know you can hear me. i’ll help you, i promise. please,” you plead, your back arching and relaxing repeatedly.

the door on the other side of the room opens and beomgyu pops his head in. “you’ll help me?” he asks, and you nod immediately. “yes! yes, please beomgyu. i’ll do anything, just please touch me,” you pull at your restraints, trying to get at him. beomgyu reaches into his pocket and suddenly your restraints are released. you’re quick to scramble off the exam table and crawl over to beomgyu who had slightly migrated into the room. you rest on your knees and place your hands in a praying position. “please, please, i need you to fuck me,” you beg. your eyes trail down from his eyes to his crotch that you’re eye level with. “i need you in my mouth, beomgyu, please.” beomgyu looks down at you with a shocked, but lust filled expression. “o-okay. go ahead, human.”

your mouth waters as you pull his pants down. your jaw drops when your faced with two giant, purple cocks. you barely know what to do with yourself at this discovery. you had had an inkling that he would be purple down here, considering the coloring of other parts of his body. “so pretty,” you mumble before connecting your mouth to the cock that sits below the other one. you wrap your hand around the one that isn’t resting in your mouth. beomgyu sighs in relief, his eyes crossing in pleasure. he staggers, his hands connecting to your hair. he strips himself of his shirt, revealing tentacles that sit on his ribcage. they’re long and seem to be able to elongate themselves. they move and wiggle down to your neck, wrapping themselves around and tightening ever so slightly.

the bulge in your throat moved deliciously under his tentacles, his instincts taking over and tightening around your throat more to feel it better. you choke and cough around him, sinking your mouth further down to take more of him. your hand moves swiftly while stroking his other cock, making sure he feels the most pleasure you can offer. you feel some of the suckers on his tentacles attach themselves to your neck. they make a slurping noise when sucking against your skin, leaving dark purple circle marks on your supple skin. you dig your nails into his hips, finding that his legs are purple up to mid-thigh.

you do your best to take the entirety of his length down your throat, but it’s physically impossible. beomgyu whimpers and whines every time you make an effort to take more of him down your throat. “okay, okay, fuck, i don’t think y-you want my cum down your throat,” he moves to push your head away from him and you pull him back. “gyu, please, need it,” you beg, giving the tip of his lower cock kitten licks. you take him back into your mouth and bob your head faster. you use your hand to jerk his other cock at the same speed, your body aching for him to cum for you. “please, please,” you chant, pleading for what you need.

beomgyu’s breath gets caught in his throat as he finally finishes, his cocks releasing cum down your throat and on your face. your whole body shakes, the feeling of him getting off to your pleasure making you feel like an animal. you remove your mouth from him and swallow to the best of your abilities. you lick your hand and do your best to collect the semen from your face and shove it into your mouth. you find that his semen is very different from that of a human man. it’s sweet and kind of tinted purple. you almost feel hungry for more to consume. you look up at beomgyu and find that he’s still painfully hard. “get back on the table,” he demands. the tone of his voice completely shifting.

you scramble to get yourself back to where you had started. beomgyu follows you just as quickly. as soon as you settle down on the examination table, beomgyu hooks his fingers under the waistband of your pants and strips your bottom half. your legs spread on their own, inviting him between your legs. the tentacles from his ribs slither to your core, one of them teasing your hole and the other finding your clit. he leans over you to connect his mouth with yours, kissing you with almost bruising force. he lifts your shirt over your head and discards it somewhere else in the room. he wraps his arms around your waist, the suckers on his arms squishing against you and sucking like his mouth would. you can feel that you’ll end up with hickies all over your body, your body turning a similar shade to beomgyu. “you look prettier like this, my salvation. you’re my color now.”

he presses firmly against you, his arms holding you in place, his cocks brushing your entrance deliciously. he peppers your face and neck with kisses while his tentacles move to wrap around your breasts. they attach and detach from your skin, leaving dark marks in their wake. “you can t-take both, right?” he asks as he moves one hand down to align himself properly. in your delirious haze, you find yourself nodding desperately. you were sweating and whining, your hole begging to be filled. “you’re acting like a bitch in heat, are you sure you’re not one of us?” he chuckles and you can do nothing but buck your hips against him.

he squeezes the tips of both cocks together, doing his best to at least make the initial stretch less unbearable. you’re soaking wet and desperate, so you couldn’t care less how much this was going to sting. beomgyu shoves into you at an agonizingly slow pace, but it makes your brain absolutely go numb. it takes him probably a good couple minutes to fully bottom out at the speed he’s going. when he finally does, there’s a very obvious bulge in your lower stomach. your jaw hung slack as your body desperately tried to adjust. “so big… so good…” you mumble, lifting your head to look down between your legs and admire the way you look spread open. your eyes then trail up to beomgyu’s face and you’re met with the most beautiful sight.

the alien between your legs had his pretty bottom lip caught between his sharp teeth, his own eyes also admiring the way he disappeared into you. you could tell he was struggling to keep his eyes open, the pleasure overtaking him. his cheeks flushed a dark pink, seeming to be in disbelief that he had actually managed to get inside his human captive. “fuck, baby, you’re sucking me in like a good girl. i knew you’d be the perfect candidate,” he brushes a hand over the bulge in your stomach before using his arm to hold himself up over you. he runs his purple tongue over his fanged teeth, before scanning your body.

“need… please move,” you plead, clenching and unclenching around him repeatedly. finally, he draws his hips back, before slamming into you. you cry out immediately, the feeling being such an intense mix of pain and pleasure that your nerves have no idea how to react. you feel like your whole body is on fire, the aphrodisiac working its magic to make your body desperate for more despite being filled with two cocks. you grab him by the nape of his neck and connect your mouths, desperate for as much contact as possible. he wraps his arms around you again, placing them meticulously so that he fills the empty space on your torso with more dark purple and blue marks.

he thrusts into you with so little mercy or care for your human state. he folds you in half, connecting his suckers to the backs of your thighs to keep you in place. his tentacles slither away from your chest and down to your core. one connects a sucker to your clit and the other forces its way into your hole along with his cocks. “gyu, fuck, need to cum,” your eyes burn with tears as your orgasm comes hurdling towards you like a train. “oh, my perfect salvation,” he mumbles against your mouth. “you can cum, but i’m not gonna stop. have to breed you,” he runs his tongue over your bottom lip as he finishes speaking before kissing you once again. your orgasm crashes over you and your whole body trembles in his hold. he holds you down tighter, your body beginning to fight against him from overstimulation.

“oh, don’t fight it, pretty girl. you know you want more. you’re practically bursting at the seams,” he taunts you. he removes his mouth from yours before connecting it to your jugular. your legs shake and try desperately to close, but his strength is much more than yours. he kisses the side of your neck before sinking his teeth into a seemingly specific part of your neck. “mine, mine, mine, all mine,” he mutters. his possessiveness over you has you inching closer and closer to a second oragsm. he can feel you tensing again, and it’s perfect timing. “gonna knot you this time, baby. it’s gonna feel a little weird, but it’ll ensure that you’re impregnated.”

you nod despite the fact that none of his words had actually registered in your brain. the tentacle that had been wriggling around inside you pulled itself out. as you came, you felt his cocks get impossibly bigger inside you. as the bases of his cocks swell and plug your hole, his whole demeanor changes. his previously mostly dominant behavior completely. he unsticks his arms from your legs and lets them rest on his hips. he leans on his elbows next to your head and strokes your hair. he looks at you like he’s never loved anyone more than you. “you’re perfect. i couldn’t have picked someone better, my salvation.” he swells inside you more and more, and you feel like you’re going to explode.

finally, you feel him filling you to the brim with his cum, and you can almost feel that he’s filling you directly in your womb. the experience has you feeling drunk. your eyes cross and you drink in the feeling of him finally filling you up. your body is exhausted and it’s almost like his knot was the antidote for the aphrodisiac you had taken. he slowly pulls out of you, a glob of cum following him. he pants, wiping his forehead with his forearm. “okay, i’m gonna go get you some clothes and a towel, and then we begin our journey back to venus.”

you raise your hand to your neck, feeling the mark of his teeth in your skin. your brain comes to an understanding that you are, in fact, his. you don’t mind all too much. “i’m sorry, i’ve never knotted anyone before. it’s a sacred practice that we’ve now shared,” beomgyu explains as he cleans you up and helps you put on robes similar to his. “um, we are mates forever now though.” you shrug, hopping down from the table. “that’s okay. i like you,” you smile and wander around the room. “i’m y/n by the way, since you never asked for my name.” you walk back over to him and admire his stature next to you.

“ready to go home?” he asks you, and you nod. “let’s go home.”
