Jack couldn’t remember the last time someone had been strong enough to pick him up, but Zer0 lifted him effortlessly, as if he were out in zero gravity. One long arm hugged around Jack’s hips, propping him up against their chest. Jack sat back against Zer0’s forearm, feeling strange and precarious being carried like this. Zer0 wasn’t exactly warm, considering the unknowable makeup of their body and the thick layers of bodysuit material, and yet as as grew used to it Jack gradually felt comforted in their lanky embrace.

Zer0/trans!Jack commission for @herkal. Ovi and tentacle dicks in here c:

Jack trusted few people. He trusted even fewer vault hunters. So some might say he’d been foolish for hiring a former assassin, someone who had previous desires to take him and his company down, as a bodyguard. But Jack hadn’t gotten this far thinking inside the box.

Besides, a collar rigged with explosives was more than enough to soothe his nerves.

Not that Zer0 was an unruly underling. Quite the contrary. They were poised and quiet, and above all incredibly, almost horrifically skilled. Several times already, Jack had had his gun half out of his holster to thwart an assassination attempt or even just shot someone who was pissing him off through the head, only for Zer0 to have already bisected them or sent their heads spinning to the glossy floor in a spray of blood. And while Jack definitely appreciate the gory fanfare, he hoped having such a skilled companion nigh all hours of the day didn’t lead to him losing his touch. Thankfully, that wasn’t something the occasional trip to the shooting range wouldn’t fix.

It wasn’t all bloodbath and ninja swords, though. Most of the time Zer0 simply stood by his side in his office, rarely showing much interest in anything Jack was doing or really saying anything at all. Jack didn’t really mind, honestly. He quickly grew used to it.

Which was why when he heard a metallic thump one day, he didn’t think much of it until he swiveled around in his chair to find his assassin collapsed on their knees, one elongated hand pressed quizzically up against their middle.

“What’s the matter with you? Eat some bad shrimp?” Jack joked. Come to think of it, he’d never actually seen Zer0 eat. Or take off their mask.

“It is my cycle,” Zer0 replied mechanically after a long moment, even as their hand continued to rub across their stomach, “there is burning right down here, I must care for it.”

“Whuzzat? Burning? Cycle?” Jack blinked rapidly. A displeased, oddly green emoticon flashed over Zer0’s helmet.

“It’s hard to explain, when I am feeling this way, I need to have sex.”

The bluntness of the assassin’s tone surprised Jack. Zer0 had never shown any particular needs common to the humans he was surrounded by. Jack had figured that the assassin just didn’t have those impulses, which was whatever—all he had really needed from Zer0 up to this point was their razor sharp senses and combat abilities.

“You….You don’t say….sex, huh?” Jack wheeled himself closer, observing Zer0’s crouched form with the detached interest of a satellite.

“There is little time, quite soon I will need to breed, I must find someone.”

“Breed, huh? So, you’re saying I should get you some kind of sexy lady alien…or. Cyborg. Or whatever.” He had no clue. As far as he knew, Zer0 could be three kids in a bodysuit.

Jack stroked his chin as he watched Zer0’s hand drift down, halting just above their groin. Jack cocked his head, waiting for Zer0 to continue, but they did nothing until Jack let out a terse sigh.

“You just need…what, you need like a hole to fuck, or do you have like….specifics or something…”

Zer0 turned their head towards Jack, a thinking ellipses appearing on their mask.

“Whoever it is, they would have to be all right, with holding my brood.”

“Brood? So uh….what does that mean, exactly. Like. Babies?” A bunch of little Zer0s might be kind of cute. Jack could probably make a whole strike force outta them as soon as they could hold a sword.

“They are infertile, they will not grow inside you, but they are my eggs.”

“Eggs. Oh. Eggs. Okay. Sure.” Jack tried feigning disinterest as a little thrill of pleasure rang through his core. No one knew about his secret porn browsing habits, of how often he hacked into weirder, slimier parts of the ECHOnet to find some primo alien porn. He’d stumbled across a particular sub-genre on accident—voyeuristically shot films of actresses getting plowed by a variety of alien fauna, either sentient or not. Bizarre creatures with weird dicks and the capacity to make the skinny girls’ bellies swell and round with cum or the occasional slippery, oozy lifeforms. He’d definitely seen a couple clips of some pushing big, round eggs out of their pussies too, and at first it scared him how much it’d turned him on but now that he was faced with the reality of living out his sick fantasy he felt little more than exhilaration.

But he couldn’t exactly let Zer0 know that. He was still the assassin’s boss, after all, and though the former Vault Hunter was working for him now, he still couldn’t afford to let a rumor get out about his less glamorous fantasies. So he continued to play the part of the genteel, self sacrificing benefactor, willing to let his employee use his body out of the pure goodness of his heart.

“All right. Well I can’t exactly like my precious bodyguard suffer through this alone. I graciously offer myself. That work for you, pumpkin?” Jack slapped his thighs before rising to his feet. Zer0 was still for a moment before they nodded slowly.

Jack wasn’t about to start beating around the bush. Not now, when he was kind of…interested to see what Zer0 had to offer sexually. He started to fidget with the buckle on his pants, yanking down the fly and letting the garment fall to the floor. He pressed his thighs together as Zer0 watched him impassively, not really looking like somebody waist deep in a hormonal rut. Jack felt a bit awkward as Zer0 stared at his crotch, analyzing the little puff of hair decorating his pussy. His big hands started fidgeting with the hem of his dress shirt when suddenly Zer0 rose to their feet and strode over in a wink, placing their hands on his hips. Jack shivered slightly, the textured palms of Zer0’s bodysuit feeling strange on his bare skin.

“This will do nicely, you have much space inside you, will it be all right?” The assassin questioned, helping Jack to step out of his pooled pants and shoes.

“Yeah. Yeah, I’ll be fine. What kind of boss would I be if I didn’t help out a needy employee?” Jack puffed his chest out in confidence, before glancing about the office.

“So. Uh. Where do you want me? How is this gonna….like….go.”

“I’m fairly certain, for the best results tonight, I should carry you.”

“Uh…carry me?” Jack felt skeptical, but Zer0 was bigger and taller than he was, and the CEO hovered at around an average weight. Besides, his desk was a bit of a mess right now and he really didn’t want to have to re-arrange and reorganize everything if it got shuffled around during their sex.

“All right. Guess you probably know what’s best with…this.” Jack held his arms up, making his body easier for Zer0 to hold on to.

Jack couldn’t remember the last time someone had been strong enough to pick him up, but Zer0 lifted him effortlessly, as if he were out in zero gravity. One long arm hugged around Jack’s hips, propping him up against their chest. Jack sat back against Zer0’s forearm, feeling strange and precarious being carried like this. Zer0 wasn’t exactly warm, considering the unknowable makeup of their body and the thick layers of bodysuit material, and yet as as grew used to it Jack gradually felt comforted in their lanky embrace.

Zer0 walked briskly, with Jack in their arms, until they were pressing him up against the massive window cresting the office. Jack’s back rested up against the solid glass, wedging him nicely between the unshakable pane and the careful hold of the assassin’s arms.

His pussy twitched in excitement as one of Zer0’s long-fingered hands slid down their stomach—which Jack noticed suddenly, seemed slightly swollen compared to the rest of their lanky frame—and to their groin. Jack watched as the fabric parted, or changed, or something, because one moment there was nothing more than the smooth meet of their thighs and the next something was morphing and bulging outwards—growing, lengthening—

Jack wasn’t sure what he had expected Zer0’s genitalia to look like, but he didn’t know if he could have conjured up something like this even with his imagination firing full-blast. It almost looked like some of the odd Pandoran flora he’d seen being grown in R&D, except a dark grey—metallic, like someone had melted down a shotgun into malleable, pulsing flesh. Tentacles of varying lengths curled and writhed around a longer, stouter looking shaft, almost like a thick stalk jutting impudently up between his splayed legs. Thin veins, full of teal blood or fluid or cum or whatever bulged and glowed in certain places around the shaft, and the entire alien affair secreted a bright, neon green lube that dripped like radioactive ooze onto the floor below. Jack craned his neck, pointing down towards Zer0’s groin.

“So….guess you’re confirmed for ‘alien,’ huh?”

“Quite an assumption, there is no real way to know, if I’m organic.”

“Guess you could just be….a reeaaaally advanced cyborg or something…” Jack honestly didn’t really care much about Zer0’s exact species in this moment. All he really knew was that that cock was huge and pulsing and wet and he wanted it inside of him ten minutes ago. He wiggled his hips eagerly as Zer0 carefully moved their groin close to Jack’s ass, his genitalia wriggling as if it were a separate entity from Zer0 entirely.

Jack grunted as the tentacles started to lap over the heavy folds of his pussy, the slime from Zer0’s genitals already beginning to mix with his natural lube. The side of the assassin’s heavy shaft rubbed between his folds, the head resting up against his lower belly as those root tentacles started to pry inside of him, wiggling their oozing tips into his hole. Jack gasped at the sudden pressure against his clit, his hole growing wetter and slicker as the winding tentacles stretched him out in preparation for assassin’s cock.

It felt far stranger than anything Jack had ever had up his cunt before, like boneless fingers or worms, and if you had asked him a day, no, mere hours before if either of those options sounded sexy he would have probably laughed or pulled a face. But right now it felt so damn good that he didn’t want it to stop—he wanted more of the assassin in him immediately, filling him to the brim and making him cry out in pleasure against the window of his own office.

“Hah…Z-Zer0….please…c’mon, more…” Jack demanded breathlessly as the tentacles probed around inside of his pussy. He sobbed a little when that sweet pressure left him, but the emptiness didn’t last long. Zer0 adjusted him slightly in their arms until the head of their cock pressed between the slick folds of Jack’s pussy, nudging its way towards his entrance as the smaller tentacles coiled around the thick shaft like vines.

Zer0’s cock felt huge, even with the lube and preparation provided by the tentacles. Jack gritted his teeth, hissing as the flared head caught on the fleshy ring of his hole. Zer0 pushed in with as much measured slowness as they could manage, but the need to breed soon dampened their patience. Jack’s teeth ground against each other, a strangled yelp escaping his mouth as Zer0 shoved the head of his cock all the way in, allowing Jack a moment’s respite before they were sinking the rest of the way in. Jack clutched at Zer0’s shoulders, nails digging into the metallic fiber of the assassin’s bodysuit.

Zer0 fucked him slowly at first, their hips moving in a steady, rolling rhythm aided by the gradual push and pull of the ancillary tentacles. However, after a minute or so they started to pick up the pace, rutting into Jack faster and faster, their cock hardly pulling in and out so much as keeping itself constantly buried inside of Jack and rutting its head against the furthest part of his insides it could reach. It penetrated unnaturally deep inside of him, further than any cock he’d been fucked by or toy he’d used on himself.

Zer0’s come took him slightly by surprise, a sudden slap of hot fluid inside his pussy that had him jolting and shivering at the sudden contrast. He whined, toes curling as more and more come throbbed into him. He could feel it traveling upwards, further than any release from any of his previous partners. Maybe that was from how deep Zer0 was embedded inside of him, or the sheer force with which the assassin was squeezing their cum inside—he couldn’t tell for certain, nor did he care to with the pleasure rocketing through his body. His own cum slicked around the fat girth of Zer0’s swollen cock, cunt trembling and juicy as the assassin flooded his system with heavy, alien cream.

And then the eggs started to come.

Zer0’s cock suddenly started to swell up an extra couple of centimeters, a heavy orb soon starting to press up against Jack’s already stretched and glistening entrance. He moaned, his insides fluttering as the first egg started to push through, forcing him to open up wider and wider until it finally slid completely inside of him. He gritted his teeth at the sudden pressure, the fullness making the muscles in his cunt quiver. It was strange, one of the strangest things he’d ever felt, but he couldn’t possibly deny that it cranked this ungodly pleasure up to ten.

Jack’s heels dug into Zer0’s slim back as more and more of the eggs were steadily pumped into him. He could feel his stomach starting to bloat against his tight waistcoat but he was too busy clutching onto Zer0’s shoulders for purchase to do anything about it. Thankfully, the assassin had managed to keep their wits about them, and deftly undid the clasps on Jack’s clothing, saving him what could’ve been a humiliating trip to the tailor. His open waistcoat and dress shirt fell to either sides of his body, exposing his bare middle.

His pale, usually sunken belly was starting to fatten, flesh tightening slowly over the eggs being shoved into his womb. Jack wanted to cringe, wanted to be sick but he felt little more than a titillating warmth alongside the slight bloated discomfort. His cunt was wet and puffy, flesh swollen with blood as arousal rushed down to his groin. His clit twitched, red and hard and pressed against the thick shaft of Zer0’s cock as it bulged and pulsed with eggs. Jack whined, eyebrows pinching upwards as more slime and eggs were pushed up into him, his stomach starting to bulge out awkwardly with smooth, rounded shapes.

“Ohh…ohh…wow…you r-really weren’t kidding…” Jack huffed, his breath starting to grow more strained as the weight of eggs in his womb started to press on the surrounding organs. He wondered briefly how much he could possibly stretch and if he could even fit Zer0’s full clutch inside of him, but that worry was quickly lost amidst the pleasure thrumming through him as more and more eggs pushed through his sensitive pussy.

Zer0 had mostly stilled, no longer thrusting and jostling. They placed their hand on Jack’s stomach, lightly, as not to disturb the eggs still filing into Jack’s innards. Their hands were still cool, despite the intensity of their breeding sex, and it felt good on the steadily stretching muscles underneath Jack’s bloated flesh.  

He had lost track of his orgasms at this point, the eggs relentless against the sensitive inner walls of his pussy, sheathed shells constantly pushing up against his swollen clit as they worked their way inside of him. He panted, his throat rough and hoarse as Zer0’s full clutch was stuffed into him. His belly had grown nearly twice its normal size, rounding out in a plump curve with the lumpy shapes of the eggs packing tightly into his womb.

Just when the firmness in his belly started to grow uncomfortable, the flood of eggs finally began to slow. Zer0 held him close, caressing his hips soothingly as the last bit of the clutch rolled up inside of him, follow by one last pulse of fluid that seals the eggs together deep within his full womb.

Jack lay slack in Zer0’s arms for several minutes, recovering from the tingling of his overstimulated body, before his hands finally fell from Zer0’s shoulders and came to rest curiously atop his stomach. He could feel the shapes of the clutch beneath him, its warmth as it rested comfortably inside of him. The shells of the eggs were not hard, rather they felt malleable to the touch, giving in slightly as if he were filled with a dense, vicious jelly.

“Nnngh…you really…packed ‘em in there…didn’t you?” Jack panted, swollen belly rising and falling with his labored breaths. A cheeky emoticon flashed over Zer0’s mask, bumping the sleek material against Jack’s cheek affectionately.  

After a couple of minutes, Zer0 rotated him carefully, cock still thick and stuck inside of him. They kept their long arms wound carefully about Jack, one supporting underneath his knees while the other lightly draped over his trembling chest. Without disturbing the CEO too much more, Zer0 stepped like liquid over to the CEO’s throne and sat with the man in their lap. Jack was far too exhausted and fucked out to care that the assassin was sitting in his chair and merely leaned back against the assassin’s chest, head tucked against Zer0’s long neck as he slowly fell asleep.
