On Our Favorite Rocket Ship

>All you wanted was a normal internship
>Even as a research undergrad, you figured it wouldn't be too tricky
>Your degree is in theoretical wormhole physics - "field work" was an oxymoron for you
>When you signed up to work at the Dimensional Research Laboratory, you figured you'd at most be watching particle accelerator outputs and fetching coffee
>Working for the famous Professor Burnet may have been a mistake
>It's a pity you didn't realize that until you'd already put on the field suit

>You stand nervously on the platform jutting from the base of a huge metal ring, fidgeting nervously in your suit
>The thick layers of various environmental protections are making you hot and sweaty, although some of that might be fear
>Professor Burnet gives you an encouraging wave from behind the inch-thick shockproof glass, and you can see an assistant fiddling with the portal's controls
>From what you've been told, this gate is supposed to create an Ultra Wormhole without requiring the power of Alola's legendary Pokemon
>Robot probes have proven that it works, and the last one has revealed a world that seems inhabitable
>Now it's a human's turn to go check it out
>You questioned why before, but nobody listened anyway

>With a sound like a dubstep remix of tearing paper, a blue-lined tear in space opens up before you
>The distortion makes it hard to see, but you can make out the yellow-tinted sky and greenish-yellow earth of another world
>Bracing yourself, you step through the wormhole before you can change your mind
>Immediately, you nearly trip and fall on your face
>The gravity must be lighter on this world or something, because you're practically bouncing with every step, even in the heavy environmental suit
>As you catch your balance, a series of green lights blink in the corner of your vision from your helmet's HUD, plus one yellow
>The world's atmosphere is apparently safe to breathe, there's no deadly diseases or particulates in the air, and the radiation levels are Earth standard
>Gravity is only about 0.75 Gs, though
>Now it tells you

>For the sake of science, you flip the latch on the back of your helmet to release it and the rest of your suit
>The helmet disengages with a hiss, and you shrug off the backpack and heavy "jacket" of the suit, sniffing the air
>It...doesn't smell BAD
>Mostly like plants, copper, and a little bit of sulfur
>You scan the area, taking in your surroundings
>Unfortunately, there aren't many to take in
>You're just to one side of a large crater filled with a greenish watery fluid, evidently filled by the bamboo-like pipes running into the crater's base
>Next to you is a much larger, higher crater, and - as you look up - you can feel a shaking in the earth that may be coming from the crater's top
>Well, your internship does depend on investigating, and hey - you're getting paid
>You start bouncing your way to the crater's lip

>You make it to the rim in only a few moments, but during those few moments, the rumblings have gotten stronger
>Curiously, you peer down into the crater's depths, expecting to see another lake of green fluid or a geyser or something
>Your heart stops for a second, then launches into a panicked staccato beat
>You recognize what's down there from your briefing on the Necrozma Event a few months back
>That's a fucking Celesteela

>A detached part of your brain starts taking notes on the situation as the rest of you begins to shut down in panic
>The Celesteela appears to be partially buried and rooted in the ground, attached to those same strange bamboo-like pipes as in the previous crater
>The ground is hissing and smoking under it, and cracks appear to be forming around where it's partially buried
>Rays of light appear to be escaping from the cracks, and the Celesteela is actually growing taller - no, it's forcing itself out of the ground
>Apparently, they are closer to plants than anything else - fascinating!
>Then the note-taking part of your brain shuts down too as the Ultra Beast explodes out of the ground, showering you in rubble

>You're laid out flat on your back by the pressure wave, the wind knocked out of you, and you narrowly miss going back over the edge of the crater
>As you gasp for breath, you see the newly revealed Celesteela slowly rotating in the air
>It turns to face you, and tilts its head in an oddly humanlike motion
>Then, in a motion that makes your heart skip a beat, it gracefully tilts that long neck towards you to stare more closely
>A detached memory from a Psych gen-ed course you took floats through your head - fear and attraction are tightly connected
>Maybe that's why you're actually finding the Celesteela's face beautiful
>And also possibly why you're starting to get hard

>You're starting to regret stripping out of the protective suit
>Sure, you've got an underlayer on, but the pants have a boxer slit in them and everything
>So of COURSE your cock is starting to poke out
>And of course the Celesteela notices
>Its - her? - head tilts down, staring at it more closely
>Then, almost curiously, she opens her mouth
>A bright green tongue emerges, and - before your disbelieving eyes - runs up your cock
>Maybe there's something in her saliva, because the lick leaves a tingling trail along your shaft even as you groan involuntarily
>She giggles, actually giggles, with a sound like a tinkling bell in an oil drum
>You're actually starting to find a fucking Celesteela cute

>With a hissing sound, her outer coverings begin to slide away one by one
>Each layer folds itself back under the others, revealing only the next one, which unclips itself and continues
>At last, all that's left is the hex-print underlayer, which splits in two on a previously invisible seam and slides back around the huge Ultra Beast's body
>The form revealed is...surprisingly humanlike
>And also surprisingly sexy
>UB04 apparently has a voluptuous humanlike body under all those layers, with a pair of proportionally large, perfectly perky breasts and a smooth, curved expanse of pale belly atop a pair of wide, round hips
>And, flanked by the remaining few layers of shielding right at the base of her belly, an equally proportional vaginal slit
>You're starting to see a problem with this

>Apparently, she isn't, because without warning one of those rocket-booster arms slides under you and picks you up bodily
>You yelp as you're pushed into the air, landing squarely on her belly
>Your head is buried right between her breasts, and so - operating on instinct - you decide to make the best of it
>Reaching up, you tweak her nipples, and are rewarded with a throbbing moan of pleasure that seems to be coming from inside an echoing metal room
>You're permitted to rub her for a few moments longer, grinding your cock on her belly, before she decides there's a better idea
>That massive rocket gently but inexorably pushes you downward on her, aligning you with her pussy
>It's somewhat puffy, dripping wet, and so huge her clit is a only bit smaller than your fist
>Welp, time to go out with glory for the sake of science

>Bracing for the worst, you get a grip on her and slide your cock into her slit
>Of course, you don't get in very far - you're of about average length, but in proportion to a Celesteela you're tiny
>Then you go for her clit, gripping it gently with both hands
>A high-pitched shriek of pleasure sounds from above you, and you can feel the rumble as her rockets start to smoke
>Well, that appears to have worked
>Leaning forward a little bit more, you take the tip of her clit in your mouth
>Then, without any more foreplay, you bob your head down and take most of her clit into your mouth at once

>Celesteela screams in pleasure, and her pussy seems to change shape around you
>The empty space around your cock suddenly closes in, becoming tight as a velvet vise
>A gush of nectar drenches your pants as the space closes - either that or she just came
>Regardless, you're not going to stop when it's going so well
>Slowly, you start thrusting into her, at the same time as you start to swirl your tongue around her clit
>The practicing for that popsicle-eating contest is paying off
>You can feel her rumbling underneath you, and her arms are twitching as their jets seem to fire almost at random
>You're only in marginally better control - now that she's somehow shaped herself for you, every thrust is a bit of heaven
>Neither of you are going to last long at this rate, and it's just a matter of seeing who comes first

>As it happens, she goes first, but only by a few seconds
>A jet of sweet nectar fountains up around you as she screams, and even around her clit you get a mouthful of it
>It's delicious, sweet like fruit juice, and - as it happens - exactly what you need to push you over the edge
>You climax then too, exploding into her with a built-up fury you didn't know you possessed
>When your orgasm finally ebbs, you lift your head from her clit, gasping for breath, but otherwise can't help but lay there for a short while

>The short while only lasts until she moves
>A rumble underneath you is the only warning you get before she beings to come up, jets firing as she moves to face skyward
>You topple backwards off her, only the low gravity saving you from some small injury
>You watch as her pussy clenches shut over your seed before her many coverings slide back into place, one by one
>You realize what's about to happen as the rockets underneath her begin to glow
>In sudden panic, you scramble to your feet and run for your protective gear in great bouncing strides
>Apparently, down the hill is safe distance enough
>Before you can even begin putting your gear on, you hear the roar of her rockets fully igniting
>You look back to see her rise majestically into the sky on a plume of green fire
>You watch until she vanishes into the sky, becoming nothing more than a twinkle of light and then nothing at all
>You turn back to your gear, and suddenly realize
>You're going to have to figure out how to report this
