YOUR AVERAGE BASEMENT CREATURE

The aphrodisiac would last a full 48 hours, lucky you. Unlucky for Knives, that wouldn’t be enough. He kept an extra four syringes to use once the 48 hours ended; just enough to last him for the rest of his heat. He’s held off for two weeks already, just one more week left. Knives isn’t sure what he’s expecting to happen. Sex, especially for a reason that isn’t repopulation, is something he’s never done before. Especially not with a human. He’s read up on anatomy textbooks, he knows how this is supposed go, which spots he should stimulate and which ones he should leave alone.

It’s the first time he’s ever been uncertain about something in his life. He doesn’t have to do this, it’s not too late to turn around and go back to his private chambers- to destroy the syringes before he thinks of using them again. Knives almost doesn’t know why he’s doing this; but he has an answer in the back of his head. In the recesses of his mind, Knives wants you to be the one coming onto him. How badly he wishes the roles were reversed- so he could be the one in control of himself while you’re helpless and needing him to stuff you full of his cum. But of course, nature was repeatedly so cruel to him. Knives refuses to be weak, to even ask you to for permission to relieve himself of his urges. You’d never agree, not to what would now be an entire week of constant overstimulation from him. 

Knives could just ride it out like he has every other year, but if he has you- why should he? Don’t you owe him something, for all he’s done? This is your role as an inferior life form, a human, to serve him. He’s just making it easier for you to do so. And sure, he doesn’t have to ask for permission or accommodate for you, but Knives feels as if he at least owes it to you to make you comfortable. You’ve done your part in this… relationship, not causing too much trouble for him and allowing him to do mostly what he wants with you. 

This is the best option, for both of you. 

With that he opens the metal door handle to your room; cold and sterile- save for a few items he let you have; the bare essentials. You have everything here, and you (rightfully) never ask for more. There is nothing from your life before him; only the things Knives decided you needed to live. A third plush blanket, a nightlight (multiple, actually), a collection of books he deemed suitable for you, as well as other items to keep you preoccupied so you don’t go mad from boredom. In the far corner of the room was a collection of items you picked up on the times he forced you to accompany him to No Mans Land to take back his brethren. The items range from small trinkets to a stuffed animal you stitched back together.

Only the bare essentials, truly. 

The awful pulsing of his lower half only gets stronger when he enters your space, breathing in your scent. It makes his entire body feels a tingly warmth. If for some reason you didn’t hear him open the metal door; you knew he was there from how heavy his breathing was. There’s a click as the doors lock slides into place. You’re both trapped with each other for the time being, either until Knives is satiated enough to pull away or until the end of the 48 hours. You look up from your spot on the bed, your figure drowning in the blankets and a Knives-approved book in your hands. Your eyes quickly make their way to the syringe in his hand, and combined with the locked door you're not eager to find out what’s about to happen. 

You knew something was up with him as of late. The sudden avoidance, how he would insist on keeping his hand on your lower back whenever he did drag you somewhere with him (Knives usually insisted you walk behind him), and his constant staring at your body. Knives refused to personally see to your nighttime routine for the past few nights as well, only demanding you wear pajama pants and a button-up pajama shirt instead of the nightgown you sleep in. 

Not that any of it should have mattered; you two weren’t a couple. Just a deranged plant and his favorite little human. Still, it was hard to ignore his strange behavior. But… watching him come through the door now, with a needle and unknown liquid inside doesn’t fill you with ease. Knives picks up on it, but he, as usual, doesn’t seem too interested in quelling your anxieties. He comes to sit on the edge of your bed, feet planted on the floor, holding the syringe up for you to clearly see.

“Nai-“ “Relax, this will only hurt a little bit.” He says, putting on his most gentle, soft facial expression. It’s hardly any different from his almost default frown, the bastard can’t even bring himself to sincerely smile. His half smile is only for himself, a boyish excitement building up inside of him. When you don’t immediately come within injecting distance, Knives yanks you by the arm to him, jamming the syringe into the side of your neck before you got any more difficult. You shriek at the stabbing pain, physically able to feel the liquid being injected into your veins, feel your muscles lose their tension. You take in multiple deep breaths, clenching your jaw. Knives finally retracts the needle, bringing you closer to hold you in a somewhat awkward position. 

“There you go,” He croons, enjoying how you’re forced to relax in his arms. You were starting to press your thighs together already, biting your tongue. He lets you go as far as to rest your head in his lap while the aphrodisiac courses through your veins. The digits of your hands and feet curl into themselves, your jaw clenching and unclenching. Knives comes to pet you, hand going lower to your shoulders and upper arm. You’re warm to the touch, even through the barrier of clothing. You can feel the smooth area of his pelvis, where his genitals would- should be. There’s a pressure on the side of your head, something soft pushing against it. You sit up, acutely aware of how hard your nipples have become. From Knives’s once barren lower half were petals, white and blooming. The petals retract and meld together to be something phallic; Knives’s dick.

It’s big, long and uncut. It looks like the penis of a man; if not for how pale it is and how it’s striped with blue markings. The head has a cerulean gradient to it. It’s… certainly something. There are no veins, no pubic hairs or anything other than it’s shape that makes it identifiable as a humans genitals. Theres a particular heat to it, you can almost feel it pulsating in waves, radiating out. It’s almost hypnotic when combined with the effects of the aphrodosiac. 

Knives is about to tell you to lay back on the bed so he can get this over with (as if this would be a chore and not the thing he’s been wanting to do for the past two weeks), but it seems you have your own plan. One of your hands rested on his thigh for you to steady yourself, the other wrapped around his newly showing girth. You felt it up, practically drooling at the sight. How disgusting, Knives thinks, ignoring the hypocrisy. He allows it, however, letting you slide your hand up and down his shaft. Your movements gain confidence after a while, and Knives bites the inside of his cheek to prevent any unsavory noises from escaping him. His breath hitches when he feels your tongue on the tip, giving kitten licks to his most sensitive part. 

You take the entire head of his penis into your mouth, and Knives almost loses all control. The sensation is so foreign to him, hot and wet. A low whine resonates from the back of his throat, watching you go back to licking, this time across the entire shaft. Precum dribbles from the tip, and Knives thinks he’s going to die when you start to lick it off, suckling on his cock for more. Knives brings a hand to your head, the other one gripping the bed sheets. From your position, you can’t see his face, but his grunts and gasps give you a good idea of what his expression must be. “You- ah- you really are eager, aren’t you?” He breathes, letting you control your pace for the time being. 

You only continue with licking at it for a bit longer, opting to take as much of him as you can into your mouth. Suckling on it, pathetic whining noises muffled by his cock in your maw. Knives’s hips twitch upward, wanting to just fuck your throat. You’re not in the ideal position for it, but it doesn’t matter to him. His hand rests on your head, and he soaks up your whining and half-protests when he begins to push your head, controlling the pace of your bobbing head.

Knives’ groans, pushing your head all the way down to take him as his hips jerk up, the cock deep in your mouth throbbing and pulsing when he cums. His cum is closer to a cool liquid, another thing separating his biology from that of a man. It’s intoxicating, but there’s so much you feel like you’re going to drown in it if Knives doesn’t get his dick out of your mouth. After a moment he does, and some of his cum drips out from your mouth as he does. You swallow what’s left, sitting upright on your haunches. Knives’ scoffs, borderline scowling as if he didn’t orgasm into you. His thumb comes to your face, wiping up the bit of cum that dribbled out, and putting his thumb into your mouth. Instinctively, you suck on his thumb, which is enough to ease the grimace on his face. 

Knives’ pulls his thumb out of your mouth with a wet pop, eyeing you over. He can see your nipples beneath the cotton pajamas you’re wearing, he can smell your desire, building up between your legs and in your lower abdomen. You’ve had your fun, perhaps too much. You’re quickly pushed further up onto the bed and on your back, reminding of how much stronger the plant is than you. Knives positions himself on top of you, spreading your legs further apart. You were still squirming, trying to relieve yourself of the mounting pressure. “Nai…” A spurt of cum comes out of his dick at that, just hearing you call his name in such a breathy voice… 

Knives decides to put an end to your misery, not like he can wait much longer either. With an inhuman speed he’s tearing off your clothing, grabbing your hips and aligning them upwards with his. A pathetic series of noises, gasps and whines, escape you as it all happens so fast. Before you can process it, you’re left bare beneath him save for a few scraps of cloth which are quickly discarded. Knives looks you over, the familiar sight of your nakedness. Every dip and curve of your body and the swell of your flesh, he’s seen it all before but in this context it’s all the more valuable to him. How soft and pliable you are in his hands, so willing to present yourself to him. 

Cum still leaks from his cock, and Knives isn’t keen on wasting it. No, you’re going to take it, and you’ll be thankful. The head of his penis nudges at your folds, and then pushes past them into your soaked cunt. Far too wet, more than you would be if he hadn’t given you that aphrodisiac; and this was only the beginning. You let out another noise at the intrusion, your walls welcoming him and sucking his cock in. You clutch the bedsheets, Knives' hands settling on your hips and waist. He’s unsure of where to start; how to start, the books he read didn’t go into specifics- but his body and his hormones do the work for him. In and out, shallow strokes to start with that gradually deepen. 

He ignores the pounding in his heart and the rush of blood in his body, the almost overwhelming instinct to pound into you as fast as possible and empty his seeds into your cunt. He’s held off for so long, he has enough control over his urges to think straight. He tries to flip the tables on this, to give himself just that bit more power. You’re beneath him, crying his name and moving your body in tandem with his. You needed him, you needed him to fuck you and grant you some relief. No, Knives wasn’t the one who was so desperate as to hump your pillows while you were at a regular check up with Conrad; never him. You were the one who came onto him; threw yourself onto his cock, it’s only right that Knives do this for you.
