Grace collapsed back against the wall with an explosive sigh, scrubbing his hands over his cheeks and dislodging his glasses in the process.
“Grace ok, question?” Rocky chirped from his ball, tapping inquisitively at its walls.
“Yeah, I’m ok, bud,” Grace murmured, dropping a hand to rub the top of the ball as though he was rubbing a dog’s head.
Even without a face, Rocky still managed to make Grace feel like he was staring at him judgmentally. He let out an untranslatable trill that Grace was now familiar with as the sound of his skepticism.
“I’m fine!” he insisted. “It’s just…” Grace slid down the wall to sit on the floor, curling into a ball. “I’m just worried.”
“Worried what about, question?”
“Everything,” Grace huffed, hugging his knees to his chest and burying his face in them. He really was worried about everything: about the additional time it would take to get to Erid after stopping to pick up their new… passenger; about how they would feed two humans (presuming their new passenger was in fact human) off of the remaining food stores and taumoeba, and considering the additional time they’d added to the journey; about how they were going to treat whatever wounds their new passenger had, what with Armando all the way at the “bottom” of the ship in thrust gravity configuration, and the passenger still up in the airlock.
It had taken Grace and Rocky some time to figure out how to safely extract the detected life form from the detected blip on their radar, which bafflingly turned out to be a human (?) and a submarine respectively. They had managed it, and now the man (?) was lying on the floor of the airlock. The interior of the submarine and the man (?) had been covered in what looked like blood (mostly dried blood, at that point, most of which had readily chipped off of their new passenger to float away in a strangely crystalline cloud as they’d moved him out of the submarine. It had become clear what it was after they’d transferred him over to the Mary and Grace could see better, though). Rocky had said he couldn’t hear any blood actually leaving his body, and Grace hadn’t seen any obvious bleeding upon his own cursory inspection, either, before he’d forced himself to look away. Grace refused to think much further on where the blood had come from, in that case, nor did he allow himself to further process the man’s (?) unfathomably odd (fascinating) physical characteristics lest he immediately descend into a panicked breakdown about how to handle another unprecedented, should-be-impossible situation. Since the man (?) seemed to be stable, breathing, and not bleeding out, Grace had prioritized getting the ship moving again and had promptly abandoned their new passenger in the airlock. He hadn’t locked the door behind him… but he had closed it.
Grace knocked his head lightly against his knees in frustration, prompting a musical whir from Rocky. They were sitting in the EVA room, Grace having just stripped off the rest of the EVA suit to put back on his more comfortable clothes. He had long since lost his sense of modesty regarding changing around Rocky. Their passenger was unconscious just on the other side of the airlock door. And Grace didn’t know what to do. Whoever they’d picked up looked mostly human, but not entirely human, and Grace had no idea what to make of that. If only he could get Armando up here. He bemoaned how difficult it was to move around the ship in thrust gravity, but they couldn’t waste anymore time not moving. His thoughts were chasing themselves in circles.
Rocky nudged his ball gently against Grace’s legs, causing him to finally look up.
“Grace want to sleep, question?”
“Nah,” Grace dismissed, rubbing his bleary eyes. “I want to stay up here.”
Rocky hummed in acknowledgement. Grace would never get over how beautiful his language sounded. “Then it is time for Rocky sleep. Grace watch, question?”
“Oh! Yeah, buddy, no problem.” Grace scrambled to his feet.
They decided to stay near the airlock but on the other side of the corridor. Rocky settled down in his ball, reminding Grace a bit of a dog circling their bed (if that dog was centuries old with engineering knowledge far surpassing that of anyone on Earth), and then he was out. Grace only lasted for a few minutes sitting beside him before he got too antsy. Sometimes he couldn’t bring himself to move or even look away when Rocky was sleeping; other times, he felt like he couldn’t settle for even five minutes. He went down to the lab to retrieve his laptop, returning to sit with Rocky and work on some of his solo projects. That worked for a while, but eventually he found himself just stressing out over the same problems that he still didn’t know how to fix (mentally avoiding the new problems that he also didn’t know how to fix). He closed the laptop with a huff. Too restless to sit still and still not ready to deal with their new passenger, especially while Rocky was asleep, Grace climbed up to the cockpit, ostensibly to “check on things.”
Grace was restraining himself from giving into the inane urge to fiddle with any of the dials when he thought he heard something below. Goosebumps rising along his spine, he poked his head out over the ladder to check on things, but he didn’t see anything. It was just occurring to him that, actually, this was one situation in which he really did need to actively watch Rocky, not just putter around the ship nearby as he and Rocky both knew he often did. If there was something wrong… well, he needed to watch Rocky.
He was halfway back down when the airlock door suddenly slammed open. Grace almost fell off the ladder.
The man (??) standing hunched in the doorway looked truly monstrous. His entire left side was wrong. His eye was practically glowing. There were teeth? Coming out of his face?? His left arm was—well, it couldn’t really be called an arm at that point. Grace didn’t know what to call it. Protrusions of some kind seemed to extend out behind him. And Grace swore he was bigger than when they’d pulled him into the ship.
Maybe leaving him unattended in the airlock hadn’t been such a good idea.
Grace shook himself out of his stupor with a gasp, struggling to get off the ladder. The man (???) snarled and lurched forward. Grace tripped and fell, scrambling to get up when—
—He was slammed face first into the wall.
Grace cried out in pain, trying to flinch away from the wall and away from the man (???) at once, resulting in an awkward spasm. He was being held down by the left not-arm barred across his back. It felt like multiple appendages, like tentacles maybe? Grace didn’t have time to focus on that. He pushed away intrusive memories beating at his mind as he was held down and tried to center himself.
“Hey, hey, it’s ok, everything is ok,” he squeaked, trying to scoot away only to freeze when he got growled at again. “We found you—we’re just trying to help. I mean, sorry we left you on the floor, I don’t know—” Grace internally berated himself for this nonsensical babble. This guy probably didn’t even speak English; why would he? (Why would a human/human-adjacent being be out here at all?) The left side of Grace’s face was pressed into the wall, leaving him looking at the open inner airlock door to his right and unable to check on Rocky on his other side. Well, well! That was fine; as long as he could keep the man (???) from noticing Rocky, then Rocky would still be safe, right?
“Let’s all just calm down, ok?” Grace continued. The man (??) didn’t acknowledge him and started to pat down Grace’s leg with his normal-looking right hand. “Are you checking me for weapons? There’s no need for that, seriously—”
The man (?) slipped his hand under Grace’s shirt, patting along his stomach, and Grace cut himself off with a moan.
Grace and the monstrous man both froze, Grace immediately withering in mortification. That was decidedly not a cry of fear. Quite the opposite, in fact.
“S-sorry,” Grace gasped, squashing his face further against the wall in a futile effort to disappear. “I haven’t been touched—I mean, I’ve been alone up here for so—Oh!”
The man repeated the motion more deliberately, lightly trailing his fingers over Grace’s skin. He made an inquisitive and amused noise as Grace moaned again, and he continued to run his fingers up and down. Grace couldn’t stop himself from arching into the touch, panting against the wall and involuntarily shaking deep in his core. The lightness of the touch felt like it burned. The man made a low noise of approval, rumbling against Grace’s back.
“What are—ah, aah!—What are you doOING?!” Grace practically shrieked as the man suddenly shifted their positions, his not-arm slipping around to Grace’s front to pull him back against the man’s chest. With his hand, he reached down to yank Grace’s shirt over his head. Ok, they were doing this. Grace was surprised to find himself not bothered at all by this development. He barely got his arms with the program in time to facilitate, only getting minorly tangled in the shirt before his head popped free, glasses hanging precariously from one ear. He reached up to fix them but got distracted by the strange limb now in view. It seemed to start as a normal human shoulder, but halfway down the upper arm it split into a mass of tentacles of various sizes, too many for Grace to easily count. He touched a small one curiously, and it curled around his finger as though in greeting. Grace was oddly charmed.
As usual, he couldn’t get himself to stop talking. “Wow, this is really something,” he admired, twirling the tentacle around like a curling vine. Or a piece of spaghetti. “How do you—”
Thankfully for all parties, the man cut him off. One of the larger tentacles slipped down his left thigh before wrapping around it and lifting. Grace gasped and flailed as he unexpectedly balanced on one leg; he would have fallen over if not for another tentacle wrapping around his waist to steady him. His head fell back against the man’s shoulder (Grace swore this guy had been shorter than him when they brought him in. Now he was larger, hunching over Grace. Conveniently, this put his shoulder at the perfect height, though). Grace turned to look at him, pressed almost cheek to cheek with the human-looking side of his face. He could just see the spiny teeth extending from the other side of his face.
“Wow,” Grace murmured in a daze, his left hand rising without conscious input to touch them. Another tentacle caught his wrist before he could make contact and held his hand away. Grace felt himself flush even redder than he surely already was. “Sorry, that was presumptuous of me. I didn’t mean to overstep—aaaah!” Grace cried out as the man went back to caressing his stomach, whining as the man dragged his hand up to pinch one of Grace’s nipples. Grace’s head lolled on the man’s shoulder as he arched into the touch, grasping at his forearm not to pull his hand away but just for something to hold onto. He felt entirely pinned in place, but now in a decidedly good way, barely holding up his own weight. Grace couldn’t hold back the noises he was making, each of his moans arcing upwards like a question as the man squeezed his chest and played with his nipples, fondling one with his human hand and wrapping around the other and pulling with another tentacle.
“How are you doing all that?” Grace whimpered to the ceiling, shaking like a leaf. The man nuzzled into his neck with surprisingly soft lips, mouthing at his skin. Grace was losing his mind. “I mean, you’ve got to be controlling at least five independently moving tentacles right now, but don’t they—mmph!” A tentacle slipped between his lips, and Grace finally shut up as his brain shut down. The tentacle was slightly larger than a finger but not by much. It didn’t press far into his mouth, simply resting heavily against his tongue. It tasted and felt like regular human skin, although it lacked the underlying press of bone. Grace’s knee gave out as he lightly sucked the tentacle, but it didn’t matter as several more swiftly curled around his waist and hips to hold him up.
The man growled into Grace’s neck as Grace let him take his full weight. More tentacles were doing something to his suspended left leg, but Grace could barely process it as the man continued to etch burning paths into his skin with his trailing fingers. He heard a thunk and vaguely put together that the tentacles had worked his shoe off before his leg was suddenly lowered and his pants and underwear were yanked down. Grace whimpered as the tentacles impatiently pulled his leg back up, jerking the clothes the rest of the way off and leaving them to pool around his right ankle. He felt delirious as his thigh was pulled even further up and out, leaving him utterly on display. His cock bobbed gently in the open air, since obviously he was completely hard, although he honestly couldn’t say he had noticed until now. The touch of air was cool against his tip where he was already leaking.
“Mmph, mmmph,” Grace moaned around the tentacle, rolling his head back and forth limply in overwhelmed pleasure. The man let out an appreciative rumble, running his hand down Grace’s newly exposed skin. Grace couldn’t help but tense in anticipation, but the man only caressed his inner thigh. Whining and trembling uncontrollably, Grace couldn’t do anything but take it as the man teased him, running his fingers over any part of Grace’s skin that he could reach except his cock, trailing from his right thigh across his belly to the inside of his left thigh and back. Tentacles caressed him everywhere the man’s hand couldn’t reach, two now squeezing and tugging his nipples while others trailed back and forth along his ribs and over his suspended leg, occasionally giving him a ticklish jolt. His left wrist was still held aloft, the tip of the restraining tentacle sweeping delicately back and forth over his inner forearm. Grace panted desperately through his nose, his whole chest heaving with effort.
When the man finally touched his cock, Grace practically screamed, entire body jerking with the instinctive strain to get closer. The man barely ghosted his fingers over his erection, running them ever so lightly from the tip to the root and back. Overwhelmed tears sprung to Grace’s eyes at the maddening treatment. He whined plaintively, sucking the tentacle in his mouth harder to sooth himself, only to squeak as the tentacles wrapped all around him tightened in response. Grace whimpered as the man cupped his balls, gently squeezing and pulling them before finally returning to his cock with a firmer touch.
Grace luxuriated in lightheaded ecstasy, letting the man do whatever he wanted. The pleasure rolled over him like lapping waves, tensing and releasing rhythmically as the man teased him. He never fully gripped Grace’s cock, only giving him the touch of his fingertips with varying pressure, occasionally swiping his thumb over the wet head. Tears dripped down Grace’s tipped back face to his temples and into his hair unnoticed, his muffled moans filling the corridor along with the man’s increasingly frenzied growls.
He did notice when the man freed his own cock from his pants, pressing up between Grace’s cheeks. He must have used his tentacles to do so, since his hand hadn’t left Grace at all. God, he felt big. … Wait, he felt big.
Grace’s eyes shot open as he felt the man’s cock press against him more firmly. He flailed, getting his right hand up to pull at the tentacle in his mouth. He didn’t actually manage to move it at all, but the man obliged anyway with a curious sound, pulling the tentacle away. He didn’t stop caressing Grace’s cock, though, thumbing indulgently over the frenulum under the head. Grace gasped, pressing his face into the man’s neck, but then he felt the man’s cock press against his unprepared rim again.
“Y-you can’t,” Grace wheezed incoherently, “you can’t, it won’t—please, don’t, it’ll hurt me.” He couldn’t get his thoughts in order enough to think through how to communicate the problem without a shared language.
It didn’t seem to be an issue, though. The man stopped his uncoordinated thrusts, smoothing his hand in a soothing press down Grace’s stomach. He seemed to gather himself for a moment, taking a few measured breaths before gently extracting the spit-soaked tentacle from where Grace still held it and lowering it out of sight. Grace didn’t put it together until he felt the tentacle press slickly against his hole.
“Wait!” Grace gasped, and the man again paused. “Do you understand what I’m saying??”
The man just stared at him for a moment before giving a disbelieving laugh. “Yes,” he rumbled.
Grace’s mouth dropped open in absolute shock. “You speak English?! Why didn’t you say anything—nnng oh my god,” Grace moaned as the tentacle pressed inside him. The man just shrugged, smirking as he began to thrust the tentacle slowly in and out. Grace breathed raggedly through the stretch, tipping his head over to rest his forehead against the man’s cheek. The tentacle curled forwards slightly inside him, pressing against his prostate, and Grace cried out.
“Like that?” the man murmured, dropping his hand back down to leisurely stroke Grace’s cock again. His voice was deep, his speech slightly garbled.
“Ah, ah, yes, yes—” Grace whined, tears overflowing once again as the man gently traced circles around the head of his cock, teasing the slit.
“Another?” the man asked, raising a slightly thicker tentacle to Grace’s lips, maybe the width of two fingers this time. Grace opened his mouth eagerly, moaning happily as it slipped inside. He ran his tongue all over it, trying to get it as wet as possible, and the man groaned, speeding up the thrusts of the tentacle working his hole open.
Grace sucked in a desperate breath as the man pulled the tentacle out of his mouth and swiftly lowered it out of sight. It pressed against his rim alongside the one already fucking him, and Grace realized the man intended to fuck him with both.
“Yes, yesyesyes,” Grace babbled as the second tentacle paused, which he took as the man waiting for permission. “Please, I want both, please—Aaah!” Grace couldn’t help but tense as it started to press in, jerking against the tentacles still restraining his left wrist and holding up his left thigh. He clutched the man’s forearm desperately and coaxed himself to relax, pressing back into the pressure as much as he could and moaning brokenly as the two tentacles filled him. It felt slicker than it should from just his saliva.
“Fuck, ‘s good,” the man grunted, thrusting firmly against Grace’s prostate.
“I-is it?” Grace asked deliriously, distracted thinking about the apparently self-lubricating tentacles. “What level of—mm, ooh—what level of sensation do you get through the tentacles anyway—”
“Still talking?” the man interrupted in disbelief.
Grace giggled, feeling practically drunk. “Oh, I never shut up. So they tell me,” he sang, dragging out the last two words as he rolled his hips back.
The man huffed a laugh as he withdrew the tentacles. Grace whined in protest, clenching around nothing.
“Shh,” the man soothed him, nosing against his temple. Grace’s breath hitched as he felt the man’s cock press against his hole, conveniently slick. Grace gave a full body shiver as the man’s lips brushed against his ear. “Ready?” he murmured lowly.
“Uh huh, yep, yes, please,” Grace confirmed dumbly. The man laughed again and pressed in.
Grace’s breath stuck in his chest. Oh god, he was huge.
“Breathe,” the man encouraged, stroking over his stomach. Grace consciously released the tension in his body, exhaling in a shuddering sigh that turned into a cracking moan as the head popped past his rim. And it just kept pressing in.
“Oh, oh, oh, OH—” Grace’s cries ascended in pitch and volume as the man’s cock filled him. He could feel his walls fluttering around the intrusion. Finally, the man bottomed out, pausing there to let Grace catch his breath.
Grace blinked overwhelmed tears from his eyes. He could feel his pulse thundering in his neck. He turned his head on the man’s shoulder and found him already looking back, his left eye glowing faintly golden. Grace really took in his features for the first time. He’d never seen anything like him. He was beautiful and breathtakingly strange.
“What’s your name?” Grace murmured.
The man’s eyes widened, his tentacles flexing in the many places they held Grace. Grace laid limply in his grip. After a pause, the man finally answered, “Simon.”
“Simon,” Grace sighed back, letting his eyes flutter closed. “’m Grace.”
“Grace,” Simon repeated reverently, and Grace’s mouth dropped open in a gasp. Why did this feel more vulnerable than having the man’s cock up his ass? (He hadn’t heard a living being say his name, in his own language, in so long.) Grace reached down to interlace his fingers over Simon’s where they rested on his stomach, squeezing his hand.
“Simon,” Grace whined, clenching deliberately around his cock. “Please.”
Simon didn’t need any further encouragement. With a guttural moan, he withdrew almost all the way before sliding back in. Grace gave a shivering cry as Simon set a measured pace, letting Grace feel the full length of him with every movement.
“Ah, aah, aah,” Grace moaned with each inward thrust, tension building in his body as Simon’s cock pressed over his prostate repeatedly. “Oh, oh, Simon—” With the tiny corner of his brain still processing conscious thought, Grace noticed the way all of Simon’s tentacles spasmed as he said his name. Well, that was easy enough to do. “Simon, Simon—!”
With a growl, Simon surged forward, crushing them both against the wall and speeding up his thrusts, hammering into Grace at the exact right angle. His hand dropped down to finally really stroke Grace’s cock, and Grace’s moans jumped an octave at the suddenly overwhelming sensations. Grace was still holding the back of Simon’s hand, and feeling his own arm follow the movements of Simon pumping his cock somehow seemed especially obscene. Grace felt like his head was about to explode.
“Ah, ah, oh my god, ohmygod, Simon!” Grace shrieked. Simon licked a stripe up his neck to his ear, taking his earlobe between his teeth. Grace thought he might shake apart. “I’m—I’m gonna—Simon, I’m close—”
Simon’s hand flew over Grace’s cock as he moaned into Grace’s neck. The thread of tension abruptly snapped, and Grace tipped over the edge with a punched out cry. His cock pulsed in Simon’s hand, his balls drawn up and his hole fluttering. Grace’s legs shook as Simon didn’t slow his pace at all, stroking Grace’s cock firmly and thrusting right over his prostate. Grace didn’t even know what sounds he was making anymore, his eyes rolling back at the overstimulation.
“Simon,” he whined thinly, trembling all over, his cock still pulsing and dripping lewdly. “Simon, please, please, please. W-want, want you—”
Simon snarled, giving a few more punishing thrusts before finally stilling, his hips pressed hard against Grace’s ass. Grace gasped as he felt Simon’s cock throb inside him. Simon panted into his neck, his hips twitching forward a few times as he rode out his orgasm.
Grace turned his head, pressing his open mouth against Simon’s forehead as they came down. They breathed together for a few moments before Simon lifted his head. He gave Grace a heavily lidded stare before leaning in and kissing him. Grace hummed in surprise but melted into it, following Simon’s lead as he pressed their lips together, sliding his tongue against Simon’s when it slipped into his mouth.
After a few moments, Grace couldn’t help but break away with a giggle, smushing his face against Simon’s cheek. “I think we did that out of order,” he faux-whispered giddily, failing to suppress further giggles. He shrieked as Simon traced a finger over the sensitive head of his cock in retaliation. “No!” Grace cried with a breathless laugh, prying Simon’s hand away and trapping it against his chest instead. Simon chuckled, too, impulsively nuzzling his face against Grace’s. Grace marveled at his radiant smile.
“Wow,” Grace sighed dazedly before he could stop himself. Simon quirked a bemused eyebrow at him as his tentacles released Grace’s left arm and started to lower his leg. “Oh, shoot,” Grace gasped, tensing as his right hip locked up painfully, finally protesting his contorted posture. Simon shifted seamlessly to lowering them both to the floor instead, ending up kneeling with Grace sprawled over his lap. Grace felt lightheaded realizing Simon had done all that and was still inside him.
“...Shoot?” Simon inquired sardonically, petting his hand over Grace’s stomach absently. Several tentacles mimicked the movement on Grace’s inner thigh, raising goosebumps in their wake.
Grace blushed, rubbing a hand over his face, only then noticing that his glasses had completely fallen off at some point. “I was a teacher!” he spluttered, groping along the floor beside them with hopes that his glasses were in reach. “I never really picked vulgar language back up even after I stopped teaching… Oh, thank you,” he said, plucking his glasses from a tentacle helpfully holding them up for him and perching them back on his nose.
“Teacher…” Simon hummed contemplatively. Grace wondered if the teeth growing out of his cheek made it difficult for him to speak.
“Oh, um,” Grace muttered, tuning back into what Simon had actually said and ducking his head. “Yeah—”
He cut off as musical trills emanated from his left. Grace leaned forward slightly to look around Simon, his eyes widening as he realized Rocky was awake. Simon followed his gaze and froze.
Rocky stood up and gave himself a little shake. “New human awake!” he sang happily. Conveniently, they still had the translator on from earlier, so Simon would be able to understand that. Grace didn’t need the translator much anymore, over two years into their journey to Erid, but Rocky had insisted Grace set it back up while they were working on extracting Simon from the submarine. Rocky had wanted to preempt any miscommunications that could arise from Grace misunderstanding Eridian while Grace was stressing out. (“Stupid human brain cannot process multiple things,” is what he’d actually said.)
“Uh,” Grace coughed, blushing to the roots of his hair (Simon was still inside him). “Um, Rocky, this is Simon. Simon, this is my best friend Rocky—”
“Hello new human!” Rocky trilled. Grace twitched towards the translator to add Simon’s name before being forcibly reminded of his predicament. “Happy new human is ok! Happy happy—” Rocky suddenly cut himself off, stilling his body as he tapped a finger against the ground through the xenonite ball a few times. Grace hunched his shoulders, bracing himself. “...What Grace new human doing, question?” Rocky asked slowly, rolling slightly towards them. He paused again before suddenly exploding. “New human sexual organ inside Grace, question!?!” Rocky screeched, the discordant notes almost eclipsing the volume of the translator.
Simon jerked back in shock. Grace groaned in abject embarrassment, burying his face in his hands and pushing his glasses up into his hair. “Rocky…”
“And Grace leaking! New leaking!!” Rocky cried indignantly, stomping his hand against the ground before apparently cringing away from the new information it let him sense. “Grace getting new fluid on the wall! On the floor! Disgust disgust disgust!!”
“Rocky—” Grace whined into his hands, but he cut off as he noticed Simon shaking under him. Oh no. “Simon?”
It took a moment for Grace to realize that Simon was laughing. It started with a chuckle, but it soon escalated to a full on belly laugh. Grace gaped as tears of mirth gathered in the corners of Simon’s eyes until Simon suddenly collapsed backwards, unbalancing Grace from his lap (and dislodging his cock, finally). Grace sprawled out on his back, staring at the ceiling with Simon’s cum leaking from his ass as Simon was reduced to absolute hysterics beside him.
“Now new human leaking!” Rocky protested. Simon only laughed harder. “And Grace leaking from another orifice, question!?” Rocky demanded.
Grace groaned, curling up on his side and hiding his face from both of them. Well. That was one way to make a first impression.
