Chapter Text
Fitch woke to a blinding light above him, and a hard surface below him. His eyes scrunched as he turned away to sit up. He was acutely aware of a pins-and-needles sensation going all across his stomach and into his thighs, and a few cute patterned band aids where he assumed something was shot into him to make him feel like this.
It took a moment to clear his head and understand the situation, and he was thankful he wasn’t strapped down, at the very least.
He and Doc had been talking about an… experiment that they wanted to try soon. It wouldn’t be bad if it fucked up, so Fitch was pretty willing to offer himself up as Doc’s subject, considering he’d brought it up in the first place.
The procedure was complex, and would take a while, but in the end it was simple to explain. Instead of getting a hysterectomy like a normal fucking person, they were going to use the organs in a similar way Fitch had turnt his lungs into functional gills.
Instead of breathing though, it would be… eggs.
Right.
His face flushed a bit at the thought, before shaking his head- ah. Doc must have tied his hair back. That was nice of them.
His head turned as the door opened, Doc in all their glory stepping through, dragging a trolley with a few things from the walk-in fridge/freezer rooms in the lab. They seemed a bit surprised he was awake, but took it in stride with a smile and a bit of flair with his hands as he locked the trolly in place.
“So! You’re awake, and I’ve already got you all numbed up . Certainly you wanna be awake for this?”
“I still need to walk you through what I did last time a bit. And make sure you don’t do anything… extra.” And maybe Fitch was looking forward to seeing the Doctor cut him open and mess with him. If he was? No one else had to know. Doc would absolutely not know how tender he got between his legs when their eyes raked over him, making sure nothing was out of place. It was worse, knowing that he didn’t even have clothes or a blanket to cover himself up with.
It was… embarrassing. Now that his thoughts were running without the dregs of sleep, his face only flushed further, and he crossed his legs unconsciously, squeezing his thighs together.
Fitch felt his stomach dip a bit when he saw Doc’s knowing smirk.
“Right! I just need to put a few marks on you, and then I can get started,” Doc seemed to shift from foot to foot in some giddy anticipation, uncapping a marker. They pretended to not notice Fitch’s squeak when they invaded his space, the cool felt tip of the marker drawing lines and instructions over his stomach. More than once, their eyes shifted down the few inches it was to the space Fitch was so insistent on squeezing together and hiding.
“All right, just gotta put this up,” they hummed, capping the marker and setting it aside, hand hovering over the tools available to them. His eyes flicked back to Fitch’s tense form and he hummed, shifting down a bit, letting his hands move back to the other man. His hands were placed on his thighs, hooking between them to pry them apart. Fitch’s indignant squeak only made him chuckle as they held his legs open. “Wh- I thought we were-“
Doc silenced him by snaking his tongue out and licking a stripe up his folds, before wrapping his lips around one of his tdicks, tongue swirling over him.
“You looked tense… I need you relaxed if we’re gonna do this~”
Fitch’s muffled whimpers we’re all the encouragement he needed to keep going, gloved hand sliding down his thighs till they were shifting just under his chin. All it took was shifting his hand a bit, and he could slip two fingers in each of his entrances, curling and slowly pumping them in unison.
“Ah- ahhshit- Doc-” Fitch's breath came in soft pants, pressing up into Doc’s mouth and fingers, hips rocking just barely. He leant back on the table, covering his face with one hand as he watched Doc work. The numbness of whatever chemicals Doc injected him with had the feeling somewhat dull, but also strangely intense in an awkward, contradictory way.
Doc moved to let their mouth wrap around both his tdicks now, sucking and massaging them with their tongue. Their smirk only widened at Fitch’s gasping, speeding their fingers up as his legs squeezed around his head.
The way Fitch’s insides squeezed around their fingers had them drooling. When he heard Fitch’s moans reach a certain point, they slipped their fingers out and pulled away, drool and slick connecting them before the strands snapped.
Docs eyes trailed up, admiring how Fitch shivered and whimpered. His legs were so shaky already, and he’d barley even done anything.
“Wh- why’d you stop..?” Fitch whined, hips moving just barley, looking for the attention he lost.
Doc just smirked, turning into a bit of a cackle that made shivers run down Fitch’s spine. “Awh, did you forget why you’re here? I can’t operate if you’re turning to jelly under me.”
Fitch swallowed, and he realized with a slight panic that the next few hours might actually do that. He nodded shakily, only focusing his attention back on the Doctor when a dull discomfort penetrated just under his navel. He gave a surprised squeak when he saw Doc pinning his hips with one hand, a scalpel in the other slowly cutting through the skin.
Blood welled up readily as the blade glided through the layers of skin over his stomach horizontally. He didn’t realize he was holding his breath till the blade was removed, only to give a shaky moan as a second horizontal cut was made where his hips turnt to thighs, straight across. Small beads of red bubbles together before dripping down his skin. His legs shook more, and he spread his legs further, gasping as Doc’s hand slid inwards a few inches as well.
Fitch gave another low, shaky moan when the blade slipped out and into another spot, right in the middle of the two horizontal lines, dragging down vertically and splitting the skin. His hips bucked up just a bit, causing Doc to mutter a curse and shove his hips down with a sharp demand of “Stay still,” before finishing the incision.
Doc watched how Fitch shivered and moaned as they peeled back the layer of flesh, blood smearing over their gloves and Fitch’s skin. His head tilted back, mouth parting as his breath grew more and more labored. Doc’s smirk only grew wider, knowing exactly why. They hadn’t injected Fitch with a numbing agent. Instead, it was a fun little serum that would make the nerves think pain was pleasure, and oh, was that paying off, now.
Doc hummed an upbeat tune as they worked on peeling back and pinning the skin, having to take a momentary break to adjust themself midway through. Fitch’s moans were… really getting to them, and their pants were already feeling somewhat tight.
“Mmm~ You’re really enjoying this, aren’t you?” Doc teased, pulling and pinning some of the muscle in the way of his procedure, their laugh high and cackling when Fitch denied it between whimpers.
When they finally got to what he needed to work on, he hesitated, hand pausing over the soft organ…s. There were two. Looking at Fitch’s embarrassed flush, it was safe to assume that he already knew.
Well, that just means more to work with. In fact… it might give them more wiggle room to try something…
Doc took one, gloved fingers caressing the hot flesh, and slowly made an incision. They slipped their fingers into the slit, biting his cheek when Fitch’s back arched off the table. The man’s sweet, needy moans had them swallowing thickly. Doc prodded around the organ, testing the elasticity, before taking his other hand and grabbing a syringe from the table. He double checked the liquid inside, before spreading the slit with two fingers, injecting the liquid right into the small ring that made up the cervix. The muscles immediately started relaxing, and after a few seconds, he could easily slip a finger from one side through the other. With the small action, Fitch’s gasps turned into neat screaming moans that echoed around the room.
“Oh! Ohh-ahhn- ahh Doc- fuck-” Fitch’s eyes rolled back as Doc slipped a second finger into the tight ring of muscle, stretching the relaxed muscle and working the serum into his flesh with soft touches. Fitch bit back a sob when a third finger entered, tears starting to well up- not out of pain, but of how overwhelming the feeling was. “Fuck- Fuck! Doc- please! Please pleasepleaseplease-”
“Shhh, I’m not done with you yet~”
“Mmnk-nnn”
When Doc slipped their fingers out, Fitch let out another string of pleads, only to freeze when he saw what Doc had grabbed next.
That was… a really big dildo.
It certainly wasn’t the largest he’d taken, but holy shit, if he took that right now he felt like he’d fall apart. The knot-like shape at the bottom only made him more anxious, but that didn’t stop Doc from lining the tip up with his entrance and slowly sliding it in. Fitch was whimpering and moaning loudly, eyes rolling back. Fuck, he hadn’t quite realized how thick it was, and it made him feel almost too full.
He took a moment to look down, and paled when he realized it wasn’t even halfway in yet.
Doc happened to look up when Fitch made that face and oh, wasn’t that wonderful. With a bit of spontaneous lust, Doc rammed it in all the way to the knot all at once, taking a shivering delight in Fitch’s resulting scream and crumpling back completely, shivering and whimpering. Oh- oh- did he cum from that?
Doc slid it out barley an inch, and the strangled gasp and attempt at closing of his thighs pretty much confirmed it.
Ohhh, that was adorable…
Doc used the extra inch he had to gather a bit of blood on their fingers and spread it over the knot, before ever so slowly working the knot in. Fitch sounded absolutely helpless underneath him like this, and he took a vindictive delight in working more of those pitiful sounds out of their experiment- ah. Partner. Their free hand went back to opening the slit up, taking a new delight in the head of the dildo slipping through his loosened cervix. At the height of the knot, Doc pulled it back out and rammed it in the rest of the way. With how loud Fitch screamed, shivering so hard he nearly looked like he was getting zapped by something, Doc wouldn’t be surprised if he’d just cum a second time.
Without a base, the knot went into Fitch completely, the large sphere stretching him and making it completely impossible to get out without one of his relaxants. The head went a few inches past his cervix and into the fleshy organ. With a smirk, Doc pressed down on the head, watching the way Fitch’s entrance stretched the slightest bit, nowhere near enough to let the dildo escape. Perfect.
With that done, they started mending the flesh of the organ, using generous amounts of pastes and injections that would speed healing up drastically. It wouldn’t do to have to wait months for him to heal, now would it?
He traced his fingers over the fleshy tubes attached to the organ, keeping one hand on it as he grabbed a pair of small scissors, cutting it out right at the base of the extremity attached to it. He set it on a tray of ice next to them, and picked up a similar round, fleshy organ, and used a similar method he used to sew up the organ to attach this one. It was repeated on the other tendril-like flesh, and with a few more injections, he turned to the other, unexpected set.
They were very, very lucky they’d grabbed duplicates of everything in case something broke or otherwise messed up, now weren’t they?
Before starting on it, they let their hands travel up Fitch’s sides, tracing soothing circles on the man’s hips. “You doing ok there? You seem pretty shaky. Is it getting to be too much?” Their tone was teasing, but if Fitch asked, they could patch him up and continue another time, or put him to sleep to finish. They both impressed that on each other days before finalizing this.
“Mmh-nnno,,, sssnice-nice please,,” Fitch’s words slurred together, eyes unfocused and barely there. He had a few fingers in his mouth that he’d been biting on, if the blood that was dripping from his mouth and down his hand was any hint. Fitch felt like his head was cottony-sweet, and every little touch sent him to shivers. The constant pain-turned-pleasure felt like getting strapped to a vibrator and not being able to get off of it- it was overwhelming and had his head thoroughly fucked out. “Hhahh-please,, pleas-e,, green- please..”
Fitch spread his shaky legs as much as he could with how much he wanted to curl up and grab onto Doc, and he gave a confused, almost surprised sound when Doc didn’t head back down. Instead, they moved around the side of the table, bloody hands moving up to hold his face in his hands, an almost soft look on his face, though still smirking like he was in on some joke Fitch didn’t quite get. “Ah, ah. I.. don't think you’re really in a place to make decisions. Whoopsies~”
Fitch just whined as Doc fiddled with his iv’s, and he shuddered when he welt a new coolness entering his arm. “How about this, you head to sweet dream land, let me help myself out, and then I’ll fix you up?”
Fitch just nodded, the fuzzy haze of sleep starting to cloud his eyes. “Good boy.. get some sleep now”
The last thing Fitch heard was the sound of Doc unzipping their zipper, before he conked out.
