Work Text:
Kaz stands carefully in the chamber shirtless. His cane is with Nikolai in the control booth. He won’t need it, and Nikolai doesn’t want him to be able to fight or injure the tentacles.
He breathes carefully, flexing his gloved hands carefully.
Nikolai’s voice comes into the chamber through the intercom. “Okay, first tentacle, Kaz. Where do you want it?”
Kaz considers it methodically. “Let it wrap around my torso a little bit — don’t let it squeeze just yet, though,” he warns him quickly.
“Got it,” Nikolai agrees.
The first dark purple tentacle comes out of the wall. It slowly approaches Kaz at eye level.
Kaz watches it while it starts to creep itself across the planes of his bare chest. It’s okay, this sensation, the tentacle doesn’t feel cold enough to trigger any panic, and it still just feels like a snake to him.
He lifts his arms up so they don’t get trapped.
The tentacle isn’t squeezing him at all. It’s most like...loosened rope around his body.
“Okay,” Kaz says aloud.
“Another?” Nikolai makes sure.
“Yes. Let this one have my thigh, I guess,” Kaz decides. “Don’t let it squeeze either.”
“Roger that,” Nikolai says, the intercom’s static filling the room.
Kaz eyes the next tentacle as it comes out of the wall and slowly wraps itself around his right thigh. He slowly lets the tentacle around his leg lift it up so his right leg hovers in the air, but his left leg is still firmly on the ground. “Can two of them pick me up? Or not?”
Nikolai gives a light little laugh. “One can pick you up, Kaz,” he corrects him.
“Fine. They can squeeze a bit; just enough to pick me up, though,” Kaz says flatly.
“Perfect,” Nikolai says to himself, although it still travels through the intercom to Kaz.
Kaz lets the tentacles pick his entire body up. The tentacle around his chest starts to rub against his nipples, which is an interesting sensation he might like. “Let the one around my chest explore a little,” he grants it.
“Okay,” Nikolai says.
Kaz feels the first tentacle start to wiggle around his torso until the very tip of the tentacle slowly circles around Kaz’s left nipple.
Then one of the suction cups on this tentacle grazes over it.
Kaz bites back a gasp; and it’s like the tentacle could tell that he just did that, because it slows down its exploration in order to seemingly purposefully lay the suction cup over his nipple, covering it entirely. “It can...suction...there. The first one, I mean.”
“Cool,” Nikolai says cheerfully. “Let me —”
Kaz’s nipple is being sucked hard by the tentacle.
Kaz cries out in minor, excited surprise.
“Kaz!” Nikolai says urgently over the intercom.
“It’s — it’s fine —” Kaz gets out.
“You sure?” Nikolai asks worriedly.
Kaz gasps a little in pleasure as the tentacle sucks tenderly on this sensitive part of him. “More. More tentacles, more.”
“...okay —” Nikolai begins, but Kaz has an amendment.
“— not one more. Like, four more. Give me four more,” he demands. His breathing is speeding up a little against his will. He’s getting tingly across his entire chest, almost ticklish in a way he’s never been.
This must be part of the aphrodisiac part of the situation, he thinks idly as Nikolai says, “Four more, coming up.”
Kaz gets a little thrill down his spine at those words. He watches as four more tentacles come into the camber through the wall. He’s panting with heaving lungs already.
“Kaz, you remember the safe word?” Nikolai’s voice asks from the ceiling.
“Yes,” Kaz says breathlessly.
“Okay. Good. Where do you want these ones?” Nikolai asks.
“On me. Around me. I don’t care where,” Kaz tells him.
“...are you sure you don’t care?” Nikolai asks cautiously.
“...wherever you need them to be, put them there,” Kaz says.
“...okay,” Nikolai trails off.
Kaz waits for the tentacles to begin to cover his body. One of them wraps itself around his left thigh and hip. He can feel a tentacle moving across the side of his growing bulge, and that’s a good feeling, at the very least.
He gasps sharply as one of the tentacles wiggles itself down into his pants past his waistband between his stomach and his belt buckle. Another one slips in after that one. The fourth one wraps up and starts to suction his right nipple.
It’s already plenty pleasurable, but it’s not nearly enough yet.
“More, more, more,” Kaz orders in a slightly desperate voice.
“More tentacles?” Nikolai clarifies. “Or more...from the existing tentacles?”
“Both. I want...I want both,” Kaz says as firmly as he can while he’s stimulated in various locations.
“...and you’ll tell me when it’s too much, right?” Nikolai asks.
Kaz nods before moaning a short little affair without meaning to as one of the tentacles in his pants digs into the front of his boxers too. It wraps itself carefully around his hardening dick.
He lays back in the air until he’s prone. The tentacles are holding him in it easily.
Kaz moans again as the other tentacle in his pants slips down into the top of his boxers to gently tap against his rim. “More — tentacles, let them — do — what they — want —” he groans suddenly as the tentacle around his cock suctions its sensitive skin.
“Two more?” Nikolai asks.
Kaz pants. He’s starting to tremble from all of the pleasurable stimulation he’s being subjected to, and wants more of. “Give me six more.”
“Six?” Nikolai sounds incredulous.
“I want six more,” Kaz agrees.
“Kaz, if I give you six more, and they do “what they want”, you’re going to get ripped apart or something —” Nikolai tries to protest.
“— you’re still — going to — keep an eye — on them, though — right?” Kaz pants.
He thinks he hears Nikolai swallow over the intercom. “Yeah. Yeah, of course, Kaz.”
“Good,” Kaz tries for a more stable voice. “Six more.”
“Six more,” Nikolai mumbles to himself.
Six more tentacles come out toward him through the thick holes in the wall until there are very much twelve of Nikolai’s tentacles surrounding him, and having their way with his body in the best way.
Kaz feels the one at his entrance start to pump some kind of lubricant into his boxers. “What the — liquid —?”
“— I think it’s an otherwise non-toxic slime that carries more aphrodisiac,” Nikolai explains patiently.
“Okay —” Kaz begins, then seizes with a filthy moan as the tentacle that had been lubing him up with that slime completely penetrates him. He can feel it twisting up into his body.
The one sucking on his cock starts to try to burrow its way into his urethra through his tip.
Kaz gives a strangled cry at that one, squirming lightly. “Not — there —” he manages.
“Which one, Kaz?” Nikolai asks.
Kaz’s eyes roll back as the one in his ass buries itself further inside, the pressure of the tentacle itself against the internal walls is enough to stimulate his prostate behind it intensely. He’s currently having the most violently euphoric prostate orgasm of his fucking life.
“Kaz! Which one do you want to stop?” Nikolai yells at him.
“Tip —” Kaz gasps, wiggling again to try — unsuccessfully — to shake it out.
Suddenly, the tentacle trying to make its way down his urethra sucks itself completely out. The sensation of the tentacle shooting out is like cumming so much so that Kaz wonders if he just came as well.
He looks down his body, only to see that his pants have been totally ripped off. They’re hanging onto his legs by threads at this point, and he didn’t even notice until just now when he looked at them.
Holy fuck —
The one pressing against his prostate starts to drill him, spinning up inside him at a breakneck speed.
Kaz lets out a loud, shaky moan. His eyes have rolled back in his head again.
One of the new tentacles — he thinks; there’s very much twelve to keep track of right now — burrows itself into his boxers as well, joining the one inside him.
Kaz feels himself stretching slightly painfully to accommodate both. But the aphrodisiac lube is working very well for him, because it’s not nearly as painful as it probably should be. He’s overrun with tingles and desire. He’s burning alive.
But it’s all so good that the idea of asking Nikolai to stop any of this is ludicrous to him.
Nikolai’s voice suddenly says, over the intercom still, “Fuck, Kaz, you’re perfect.”
“I’m — it’s — it’s so — fucking — good —” Kaz gets out in a strained voice that he doesn’t know if Nikolai was even able to decipher any of what he just tried to say.
He thinks he hears something unzipping, but he’s not sure. The slick sounds of the tentacles pulsing inside his body, moving around it, and suctioning it aggressively, are coving up a lot of what he might have once been able to hear quite clearly.
Kaz feels one of the other tentacles wrestling its way into his ass with the other two, except this new one is moving in and out and in and out, whereas the other two twist around inside like screws. And all of them are jolting Kaz with overwhelming euphoria every time the new one slams into his prostate.
He just moans for a while; every time he thinks he’s successfully caught his breath, he starts moaning along again.
One of the many tentacles comes up and starts to plug up his mouth.
Kaz shakes his head to dodge it. “No mouth — no mouth —”
The invading tentacle dips down instead and helps the other tentacles strip him of his now tattered boxers as well.
Kaz is fully naked in this chamber with them now, but a) he’s very much covered in tentacles right now, inside and out, so it’s not like anyone could see much anyway, and b) he doesn’t really care. The only person who could potentially see him is Nikolai, and he’s okay with that. Of all the people in the entire world to see his entirely nude body, Nikolai is the only one who even makes the list.
He feels one of the tentacles inside of him start to suction the wall of his prostate, and oh fucking god, that is so perfectly mind-numbingly euphoric that Kaz cannot even speak now. He’s staring wide-eyed up at the intercom and camera on the ceiling. He’s breathing harshly and often. He’s shaking so violently with pleasure that he vaguely wonders if he’s going to die of overstimulation.
Is that possible?
It feels pretty possible right now.
He is completely and totally overwhelmed to the point that he’s starting to silently weep with the way he is being utterly demolished from the inside out by tentacles.
Kaz feels one of them starting to play with his sweaty hair. He sighs once, only for his breath to hitch loudly and aggressively again a second later, because the suction on his prostate is continuing, rendering him paralyzed with pleasure.
It’s starting to hurt just a bit from how he’s been stretched out with three fucking tentacles. His dick is on fire from being sucked on so much by warm suction cups.
But...he wants a little more pleasure, just a little longer.
So he holds off on saying anything about the minor pain.
He lets himself cum one more time — when he can actually kind of feel it happen.
Then he hears Nikolai gasp sharply, then moan long and loud into the intercom.
Kaz is dizzy with even more pleasure somehow as he registers that everything is getting tender now, his entire body. He finally gasps the safe word. “Red —”
There’s just a second of delay before the tentacles are withdrawing from his body entirely. The ones holding him in the air help lay him gently down on the ground of the chamber where the remains of his clothes lay under him.
The tentacles suck themselves back into the walls through those holes, leaving Kaz in a panting, shivering heap on the ground.
He turns and curls up into himself instead of staying on his back the way they’d placed him down.
Kaz’s teeth chatter hard and his entire body tries to regulate itself by itself, to dubious results.
He hears Nikolai talking to him. He tries to tune in.
“— Kaz. Kaz. Kaz. Can you hear me? Kaz. Kaz. Kaz. Tell me when you can hear me.”
“Hear,” Kaz pants.
“Okay. Okay, good. I’m going to bring you some clothes and your cane. And a few towels. You’re okay. Just give me a few minutes,” Nikolai instructs him.
“Yes,” Kaz gasps his consent.
The intercom shuts off completely.
Kaz lays there in a shuddering pile as slime drips off his body into a puddle on the floor.
That’s when he suddenly realizes that he needs to keep having sex. His cock burns with need and desire and arousal still. So he reaches down with his gloved hand, starting to give himself a slow hand job, trying to ease himself down off the eternal high he got from the aphrodisiac slime that still oozes off and out of him.
Nikolai comes in, stopping short in the doorway to stare down at Kaz.
Kaz looks hazily up at him while he massages himself.
Nikolai’s got a bundle of clothes and towels in his own gloved hands.
“Slime,” Kaz croaks.
Nikolai seems to shake himself and hurry toward him. He starts to mop the slime up off the floor before draping a towel over Kaz’s bare body.
Kaz shivers. His teeth chatter fiercely.
Nikolai pauses as he’s moping up the slime. “You doing okay?”
Kaz nods quickly. He’s about to cum again, actually. He doesn’t know how he feels about Nikolai watching that up close and personal right now.
But then his fuzzy brain registers that...Nikolai just watched and helped him be fucked by tentacles. So it’s probably fine.
Kaz grits his teeth as he gets to the salivating brink.
“Painful?” Nikolai asks worriedly.
“No judging,” Kaz manages in a breathless voice.
“None,” Nikolai says just as Kaz explodes one more time.
His cum shoots out over his glove and across the floor Nikolai just mopped slime and Kaz’s old cum off of.
“Feeling better now?” Nikolai asks kindly as he starts wiping up Kaz’s new cum now too.
Kaz nods wearily. He doesn’t know if he has the energy to snarl at Nikolai for treating him like he’s glass. He lets go of his cock slowly to make sure he’s actually fully done.
He thinks he is.
He makes his gloved hands grab the corners of the towel over him, starting to dry his wet body off of the aphrodisiac slime more. He gets this towel sopping wet quickly, but Nikolai just hands him another dry one.
Kaz sits up slowly on a very sore ass to dry himself off more.
Nikolai silently mops up the slime and cum Kaz had been laying in.
When all of the slime and cum is collected in towels, Kaz reaches his hands out for the clothes Nikolai put just outside the chamber.
Nikolai leans back and snags them from behind himself to hand them over to Kaz.
Kaz watches as Nikolai averts his eyes deliberately while Kaz gets new boxers and pants on. He does appreciate the attempt to give him some privacy, despite what Nikolai just witnessed not ten minutes ago.
Nikolai brought him his shirt, too, so Kaz puts that on too. “Do you want me to grab your cane? To help you get up?”
Kaz hesitates. “...yes.”
Nikolai gets to his feet and takes the wet towels away in his blue gloved hands. When he comes back, he’s got Kaz’s cane.
Kaz uses it to stand on achy legs and ass. It feels like he just ran, like, five miles at record-breaking speeds, then sat down on something knobbly for way too long. He hobbles slowly to get out of the tentacle chamber.
“Here,” Nikolai says near him. He wheels a chair over to Kaz.
Thankfully, the chair has a thick cushion on it, which Kaz appreciates Nikolai’s foresight to include.
He gingerly sits down, holding his cane handle tightly. He’s still trying to regulate himself, slowly but surely.
Nikolai crouches down in front of him.
Kaz looks down at Nikolai as impassively as he can. “Did you get what you needed?”
Nikolai nods quickly.
“...did you get more than you needed?” Kaz asks pointedly.
Nikolai hesitates. “...maybe...”
Kaz smirks down at him at that one, because now he’s certain Nikolai did, in fact, cum as well at the end there. “Okay,” he says simply.
Nikolai watches him warily. “...okay?” he verifies.
Kaz shrugs. “Yeah, okay.” He doesn’t think he minds being visual pornographic material for Nikolai in specific to climax to.
“Okay. Okay, good,” Nikolai says quickly. “Any...any questions for me?”
“Yeah,” Kaz says before he can stop himself. “Yeah, I have one.”
“Okay? What is it?” Nikolai asks, digging into his pocket for a small notebook.
“...would you need it done...again?” Kaz tries to force the heightened shame to be more bearable for right now. “Any time soon?”
Nikolai pauses, staring at him before starting to grin. “Maybe on Saturday, we could try again?” he suggests, overly casually. “Just to make sure of the data we already have, you know; make sure it wasn’t a fluke.”
“Saturday it is,” Kaz agrees as he stands carefully with the help of his cane.
Nikolai helps him leave the lab by unlocking the door for him, and telling him, as he leaves, “Take it easy until then, all right, Kaz?”
Kaz waves him off.
The door shuts between them.
Kaz makes his way to his car, already thinking about how exactly Saturday is going to go.
