I need part 2 of that Alien BF, wanna see how my alien guy FUCK

I do too, trust, I do too. And believe that bro has been doing his homework.

I imagine he first discovered human sex during a romance movie you were showing him in the ship’s recreation area. It had been a long time since you had seen the movie too so you were excited to see their romance bloom again. But you had completely forgotten one vital thing. A tiny little sex scene that happens in the middle of the movie.

When it appeared you scrambled to skip past it. But at the same time, the remote conveniently went missing. Alien man saw it all and was enraptured.

Afterwards, when he asked you what that was, you bashfully explained that it’s a human mating custom. Alien man was in awe. That wasn’t how his species mated… but your version seemed like much more fun. He wondered if you’d show him how like you’ve been showing him everything else about humans. He wanted you to show him. And only you.

The idea of another member of the crew doing this with him made him recoil in disgust. No, you were… his mate. The only one he could do it with.

But he also wanted you to enjoy it. He didn’t want to trip over himself and be the only one feeling good from your first time together. So, like everything else he’s been learning about, he knew he needed to study. Getting your computer was easy given that he’s always had free access to all of your things. It was quite difficult to navigate the strange device but he remembered your lessons and found the search bar.

It took a few tries to word “human mating rituals” right to get the results he wanted. Eventually he got there. Each time he’d come back to study some more it got easier to navigate and find what he wanted to learn. He’d spend hours studying, trying to be the best he can for you. And every time after his member would ache with excitement to be with you.

Yet he never took care of himself, waiting patiently for the day he’ll be inside you.

Alex rolled onto her side, and was a little surprised to see Kelly Olsen laying next to her, turned away and curled up the Egyptian cotton of her bed

(their bed)

snoozing softly in the morning light. Alex took the time, as one does, to admire the vulpine curves of Kelly’s back and the elegant sweep of her shoulders. She wanted nothing more but to lean in and plant a soft kiss on the back of her neck and wake her, which would hopefully lead into a glorious Saturday morning of sun-kissed, gentle lovemaking that would result in an forgotten breakfast and breathy declarations seared into hot skin with caressing fingers and tasting lips.

Unfortunately her fucking phone was going off.

Alex rolled out of bed and snatched it, relieved that she hadn’t disturbed her girlfriend. She threw on a button-down as a makeshift robe and plodded out into the kitchen.

She wasn’t expecting a call from…

“Lena?”

“Alex?”

“Yeah, what’s up? You don’t call me often.”

“I need help. It’s an emergency. Sort of.”

Alex glanced back at Kelly’s languid form and one long leg slipping out from under the sheets.

“Where’s Kara?”

“I can’t talk to Kara about this. It has to be you, Alex.”

“Okay, sure,” Alex said, warily. “We can grab a coffee later at-“

“Alex, it has to be now and at my place. This is serious.”

Alex bit her lip. There was a compelling urgency to Lena’s voice. Alex didn’t have Kara’s super senses but she could pick up the nervous energy and hint of feed behind the words.

“Okay,” said Alex. “I’m on my way.”

Alex pulled on her cleanest pants and most readily available tank top and scribbled a note for Kelly (encouraging her to either stay in or be back in bed by the time Alex returned, as their business was unfinished) and grabbed her car keys.

Rising her bike would have been… a sore subject, as it were.

Morning traffic was surprisingly light and she made good time. Lena buzzed her up and she walked into Lena’s weirdly cold penthouse, and found her sister’s best friend pacing rapidly back and forth, dressed in a hoodie and hugging herself.

“Okay,” said Alex. “I’m here, Lena. What’s going on?”

“I’m pregnant,” Lena blurted out, before Alex had finished speaking.

Alex stared at her.

“Funny, I always thought you were a virgin.”

Lena glared at her. Alex knew why Kara was so fascinated by her- she had those big pretty eyes that radiated sadness and set off Kara’s protective instincts. Alex had figured out a long time ago that these two dipshits should just bang it out, but it wasn’t really her place to tell them, especially if it meant outing Lena, or dealing with Kara’s baggage from her weirdly fascist home planet and its bizarre ideas about sex.

(One example of said baggage being her sister’s heart breaking over the alien fuckboi from the asshole planet. If only Kara had realized that her gorgeous kind billionaire best friend was in love with her… you know, before the whole world domination Kryptonite laser thing)

(People who aim orbital fusion cannons at their friends should not cast stones, Alex had decided)

“Alex?”

Oh. Lena was talking. Alex pretty much blue screened there.

“Right, you’re pregnant. Are you sure?”

“I’ve taken two tests, and I’m late.”

Alex rubbed at her chin. Lena looked like a drowned rat, more than a little terrified.

Alex swallowed hard.

“Okay, first question. Did someone hurt you?”

Lena looked up sharply. “What? No.”

Standing to pace the room again, Lena rubbed at her arms as if she were cold.

“So um,” said Alex. “Do you need my help with…”

“I just need someone I can talk to that isn’t Kara. I can’t tell her yet.”

Alex swallowed. Hard. “Okay. Tell me what’s going on.”

Lena sighed and stared out her balcony window.

“Do you remember that game night where we all got sloshed, last month?”

“Yeah,” said Alex. “You hosted. As I recall, Kara was the last to leave.

“She didn’t leave. I… I did something stupid. I tried to seduce her, clumsily. I was drunk off my ass.”

Alex tensed, the hairs on the back of her neck rising.

“Oh,” said Alex. “She brushed you off and you went out for a hookup? I’ve done worse. Are things okay between you?”

Lena stared at Alex as if she’d just grown a second head.

“No, Alex. Kara spent the night. She insisted we not do anything intimate until we both sobered up, but I talked her into staying in bed with me.”

Alex sighed. “You got any of that expensive single malt? Your dad’s brand?”

“It’s eleven in the morning.”

“Well, it’s not like you can drink it. You can have juice.”

Lena glared at her. “Cabinet by the fridge.”

Alex ended up pouring two glasses of cranberry juice and sat down at the kitchen island, pushing one over to Lena.

Lena sighed. “I don’t want to get into the details but we were definitely sober when we woke up.”

“And?” said Alex.

“We, um, we had sex,” said Lena.

“And then she got weird and brushed you off and you went out for a hookup?”

“What? No! Just let me finish telling the story.”

Alex sipped her juice, enjoying the bite on her tongue. “Okay.”

“We’ve been sort of seeing each other ever since. Quietly, keeping it to ourselves. Kara is…” Lena sighed, “she’s very protective and she’s afraid that you’ll get upset if you find out we’re together.”

Alex’s fist closed tightly around her glass.

“Lena,” Alex explained, “I’ve forgiven and forgotten a lot from you, but I’m having a hard time understanding how this happened if you’re with my sister. Did you cheat on her?”

Lena looked up sharply from her glass. “What the fuck, Alex? How could you even ask me that? God, am I ever going to be good enough for your sister? I know I fucked up. I know what I did was wrong. Hurting her was the worst thing I have ever done and I would trade anything to take it back, but we are in…”

“Okay,” Alex cut her off. “Fine. Our lives are fucking weird, so I’ll give you the benefit of tbe doubt. But usually you being pregnant would imply that a man was involved somehow.”

Lena blinked. “What?”

“You’re pregnant. There has to be a father.”

Lena stared at her in abject confusion.

Then she said, “Alex, Kara is the father.”

Alex looked at her for too long a moment.

“I’m sorry but what the fuck, Lena? What did you do?”

“What did I do?” Lena demanded. “It’s not my fault! I mean it is as much my fault as it is hers, but we weren’t worrying about protection the first morning and after that neither of us brought it up. I know, I’ve been stupid, I just…”

Alex’s mouth fell open.

“Protection? You and her? What the fuck?”

Lena took a long pull of cranberry juice and winced at the tartness.

“You didn’t know?”

“Know what?”

“Apparently, under a yellow sun, Kryptonians can, um, adapt to a sexual partner’s body.”

“Okay, okay, okay!” Alex snapped, “okay fine my little sister… with you… and you’re pregnant. Fine, we’re on the same page. What now?”

Lena stared at her, biting her lip as she sought answers.

“Are you going to keep it?”

“Keep it?” said Lena. “It’s Kara’s. Of course I will. That’s not even a question. I’m just… I’m scared, Alex. What does this mean? How is she going to react? What if… Jesus, I’m carrying a half-Kryptonian baby. Is that even safe?”

“It worked out fine for Lois and Clark. Twice. You’ll be okay, if having the baby is what you want.”

“It is,” said Lena. “Kara makes me deliriously happy, Alex. She was like a knight in shining armor that night and she was so kind and gentle the next morning and it’s like… like this was natural. We both fell into it so easily that it was like it had always been this way. I love her. I love her so much.”

Lena was red faced, looking embarrassed as she cast her eyes down. Alex reached across the table and took her hands.

“Well, I’m glad you dipshits figured it out. Watching you two blush and stammer at each other for another five years would’ve killed me.”

“ALEX!”

“If you want my blessing, you have it. I’m sorry I doubted you, but in my defense, I didn’t know she could… do… that.”

“Uh, right,” said Lena. “I want to call her and ask her to come over now so I can tell her. I know this should be a private moment but… can you stay? It just feels like you belong here for this.”

“Yeah, Lena. I’ll stay.”

Lena smiled.

🎉Event Posting Day!🎉

It's been such a joy to be involved in the creation of the amazing Zine O'Biology, the first (as far as we know) Star Trek In-Universe Xenobiology Journal. Over 40 wonderful contributers, both writers and artists, wrote/drew scientific journal articles, letters to the editor and advertisements for in-world products and services.

It's fascinating, insightful and, in many places, hilarious. Definitely worth a read, so check it out! I've included sneak peaks below of some of the artwork I created for both journals and advertisements.

The Hunt

You’re running through the woods, doing your absolute best to escape from the creature hunting you. Unfortunately, you’re outmatched and the huntress has no intention of letting her prize get away.

Content Warning: female reader, primal play, alien smut, alien anatomy and rough sex.

Your heart is drumming in your chest. You know she is out there. The occasional click and growl. The rustling of branches. You can’t see her, not that sprinting through the woods as fast as your legs can carry you remotely helps with that, but that primal part of your lizard brain knows you're still being pursued.

You duck behind a tree, gasping for air as you try to compose yourself. You’re making so much noise, but your chest is spasming so much you couldn’t slow your breathing if you tried.

You can’t hear her footsteps, she’s too skilled for that. Peering around the tree you manage to make out the faint shimmer. Thank the heavens for the rain or you wouldn’t have a hope in hell of spotting her through her active camouflage.

Her form stops moving and you know you’ve been spotted. An amused thrill emerges from the massive shape before she rushes you. How something so big can move so fast you have no idea.

You scramble to your feet, slipping in the mud. Your clothes have been long since ruined but you have far bigger problems.

The tree behind you explodes, large invisible blades splintering the trunk. You would scream, but you still haven’t caught your breath.

There’s no point in turning to look behind you. If you could even see her you would just realize how utterly fucked you were.

Your only option is to keep going. At some point going down the hill becomes sliding, then tumbling. Banging against a rock and scratching yourself on a branch as you claw your way up the other side of the ditch.

All is silent. At least you can’t make out anything over your heavy breathing. You’re alone now, or at least you have a moment of respite. There’s no way she isn’t still watching you. She’s an expert hunter, a predator, your odds of escaping are virtually none. But you have to try.

A growl emerges from the woods around you. You spin on shaky legs, struggling to pinpoint the origin. You’re so slippery caked in mud, you can barely stay on your feet. Sure it helps to hide your heat signature but your exertion increases your body temperature far too much for it to be of any use.

Your own attempts to flee only make your position more obvious. A branch snaps above you, she’s in the trees. It’s enough to give away her position though.

You turn and run.

It’s easy enough to realize your mistake before you even can process why. The thing flies directly at you, your own panicked brain sending you right where she wanted you.

One moment you're turning, the next your legs are being pulled out from under you, the bola tying you up as you roll down the slope through the mud.

By the time the pain subsides and you manage to start to untangle yourself you hear her thump to the ground. Footprints appear in the mud as the invisible figure stalks towards you. The rain is blocked by the trees here but the occasional droplet makes her form spark into existence.

Crawling is futile, you’ll never get away without the use of your legs. But she’s towering over you before that could ever be an option. Her hulking figure appears. Her silver featureless mask, her writhing tendrils of hair, her toned and muscular body.

She reaches down and grabs you up by your jacket. Her other hand reaches up to unclasp her mask, her mandibles flare as she lets out a roar of triumph.

You’ve lost.

Tossing her mask to the side she picks you up with both arms, pinning you to the tree effortlessly. Her claws tear off your cheap clothing already long ruined by blood. You're covered in bumps and scratches, tomorrow you’re going to be extremely sore.

She’s saying something, without your translator you're at a disadvantage but you’ve spent enough time in her company to recognize the clicking gruff gloating of victory.

No reason to make it easy. Unfortunately, she knows you too well, your brief attempt at struggling doesn’t remotely budge her. When she slips her claws between your legs in response you can’t help but tense.

She laughs then, unbuckling her belt and tugging off the rest of her armour. With one arm less to keep you in place you can wiggle, not that it gets you very far, the tree bark digging into your back.

She clicks at you in warning before tugging you against her broad chest. The tentacles between her legs are already grasping at you, sucking to your thighs and trying to wiggle between your legs.

You kick at her, petulant more than anything. A large hand wraps around your throat, gently restricting airflow as she lets out a pleased growl.

She’s always liked this. She’s a hunter after all, what fun is it if the prey surrenders?

Whispering something in your ear you feel her forked tongue trail down your neck. She holds you with one arm and spreads your legs with the other.

You’re utterly soaked, as to be expected, but she would still be teasing you about it if she wasn't busy slipping her tentacles inside you. They sucker your bodies together and hold you in place as much as they can.

You know how sensitive they are, just like her hair tendrils. Unfortunately with your hands pinned you’re at her mercy and can hardly tease her.

You groan as they fill you up, wiggling deeper.

She lets out a purr, licking at your neck as she fucks you, her clit rubbing against yours.

The breath you had only started to recover is forced from your lungs. When her grip starts to falter she presses you against the tree, manhandling you so she can fuck you properly.

As whine leaves you as you clench around her, her tentacles never leave you though, only burrowing and wiggling even deeper, attaching you wide.

That would be enough to make you cum, but her heat sliding against you is just too much. You’ve never been particularly vocal, but she always manages to fuck you hard enough that you lose control of yourself.

Your fingers dig into her leathery skin, your cunt fluttering as your orgasm approaches. You can’t take it, too much to be pleasurable, too rough not to be painful. She’s using your body, claiming her reward.

But you’re cumming regardless, your muscles spasming, if she wasn’t pinning you against the tree you would have lost your grip. Your head falls back against the bark, your eyes tightly shut as you clench your teeth. Your vision has gone white, cumming so you can’t feel anything else, but she’s not done yet.

Your muscles can’t keep up anymore, too exhausted to not just clench down. Your gushing, drenching her tentacles and cunt as she keeps fucking you. You’ve lost any control of yourself, you can’t even breathe.

She howls, her crest slamming into the tree inches away from you as her mandibles nip at your shoulder. She cums, her weight crashing into you and nearly smothering you as she tenses. Her own wetness mixed with yours.

She’s got no eggs to fill you with at this time of year, not that you were a male that could fertilize them but that only makes it more fun. But quite honestly considering you’ve been cumming for a solid minute you think that might break you.

When she finally releases you she takes you into her arms rather than letting you slump to the middle ground. Cheap clothes are one thing, you’re far too precious.

“Fuck,” is all you can croak, your pussy still thrumming with overstimulation even as her tentacles gently and lovingly ease themselves out of you.

She presses a kiss to your forehead, her fangs ticking your foreheads. 

“F-hmm,” you groan.

She laughs weakly and gathers her things.

Your vision is still spinning as she carries you back to her ship. She’s going to spend the next week panicked about every scratch and bruise she gave you but it would be so worth it for this.

Weakly you promise yourself that next time you’ll manage to escape. Even if you know that definitely won’t be the case.

so I need to ask this so if Eddie is one who had the baby or conceived wouldn't he be transmasc??? (I'm just wondering)

I mean, I’m def not at all opposed to transmasc Eddie!! But in my mind (and little AU of WIPs and doodles) it’s more like Venom dropping his symbiotic drops – as he does – which had mixed with some genetic material from Eddie while they were getting freaky and it just merged and adapted. Inside Eddie… idk how it got there. I’m not a scientist.

But the symbiotic fluid then took the role of the egg and ALSO formed its own amniotic sack simultaneously! (Don’t ask me why it would do that… this is my alien mpreg headcanon… I can’t believe I am even saying all these words for all the world to read! But I think it was just trying to emulate human dna or smth)

The hybrid embryo then attached itself to any available organ for support and fed off Eddies nutrients the same any symbiote would, effectively and falsely appearing human. (In my fic WIP I do reference a shorter gestational period and that the newborn hybrid baby spends more time asleep. I also think Venom has a weak telepathic link to the baby and can occasionally influence their mood, but that has nothing to do with the question asked…)

I have a lot of time to think thoughts while drawing, ok?

ik you didn’t ask for details… but I had to take the opportunity to talk about the symbrock hybrid baby!!!!!! (also I drew this in response to your ask too)

Turns out I never posted it here, but three years ago I rendered @jayrockin's character Talita's upper respiratory system just for kicks, and since the inner workings of her head are still knocking around in mine, she gets to be a Blender file now! The muscles and bones I've added to this new render aren't *necessarily* canon for this species' design, but speculation is fun : )

Julian thinks a lot about what Garak hides under those tunics. For entirely medical purposes...

Small lesson on Koolu reproduction.

They are hermaphrodites with their genitals at their rear end. Both partners can get preggo simultaneously during the deed. They usually carry one offspring and give live birth.

[juicyolpickle]

Anatomy Diagram Concept Thoughts - I’m gonna be honest. When making this simplified diagram I had no idea what i was doing and what i was going for as this is my first time doing thing aaaand I didn’t get to figure out what type of atmosphere/environment they live in yet to get a good idea on what organs they might need to assist them in their daily lives. I just took inspiration from human and animal organ anatomy to build a simple idea before planning out the final result. And seeing how their design isn’t too alien and might even be considered mammal like, it isn’t too far fetched to develop organs that resemble closely to ours.

Planning - One thing I need to figure out before redesigning the anatomy entirely is what is in their environment, what their atmosphere is like, and what ancestry branch they stemmed from to have evolved their current day features.

One thing I am sure of is them having a baby pouch, which would be the uterus equivalent to the Zaabua and having the ability to change their sex depending on what role they are positioned in. I took inspiration from snails and how they are hermaphrodites and have both organs for ….. the deed‼️😨

speaking of megamind and weird alien anatomy, i was looking through some of my old headcanon doodles yesterday

i realized that one of my concepts was that instead of megamind's head actually housing an enormous brain (which irl would cost an ENORMOUS amount of energy to maintain with diminishing returns), he actually has a fairly human-ish sized brain.

instead, his skull is somewhat concave and most of the flesh in his forehead is actually adipose tissue similar in structure and function to a dolphin's melon. and also his sinuses are enormous and extensive and they have phonic lips similar to a dolphin's in addition to his larynx, so he can make dolphin-like clicks/whistles that sound like they're coming either out of his nose or through the center of his forehead.

the phonic lips are circled in red. as you can see i gave him quite a lot of them, so he can probably make a whole bunch of weird alien sounds.

i can't decide whether i want his melon to be squishy like a beluga or more rigid like most other dolphins. logically, the more rigid melon probably makes the most sense, but the idea of megamind having a squishy head is just so FUNNY to me.

[awful-little-goose]

Ok ok ok I MIGHT have thought about what the doppelgängers from TNMN (not to confuse with TMNT, the show about funny turtles) may look like for real, and what their physiology may be like, so…YEAH

ALL FOLLOWING INFORMATION ARE STRICTLY MEANT FOR QUALIFIED D.D.D. AGENTS.

ALL FOLLOWING INFORMATION ARE ONLY RELEVANT TO THE DOPPELGÄNGERS’ “true” FORMS.

ONLY A FEW SUBJECTS HAVE BEEN COLLECTED, DATA MAY BE INCOMPLETE.

size (average) : 850 cm in length (27’8), neck and tail included

Number of limbs: from four to unknown

Sexes : unknown differences, supposedly without sex

Life span : unknown

Diet : strictly carnivorous

Intellect : varying from ext. low to ext. high intellect, notably bad at lying for most although highly manipulative and skilled individuals exist

fluids produced such as blood and saliva are acidic to some degree. Further testing may be needed. Each cleaning must be followed by a deep wash of the area with water. Agents are expected to proceed with caution.

Bone structure is mostly cartilaginous and sparse, allowing great agility

Not mammalian, unclassified

The “hairs” covering the largest parts of their bodies are actually tendrils, able to morph in shape, size, texture, color. Each tendrils has a nervous system

“Hands” appeared to be uncovered, probably for scavenging purposes. When transforming, the tendrils extend to the hands of the doppelgänger to cover them

Four to 10 eyes (maximum recorded, may be more)

Each individual seems to possess one to three “cores”. Destruction of the individual is only complete once all cores have been destroyed. Cores maybe be moved around by the individual within its body. Function of cores unknown

Destruction of cores possibles with the following: EXTREME HEAR ; BLUNT FORCE ; CRUSHING ; SHREDDING ; HIGHLY BASIC SUBSTANCES* ; ELECTRIC SHOCK

All recorded individuals are shown to be highly aggressive: never let your guards down. Failure to incapacitate the doppelgänger due to hesitation will be met with severe sanctions.

[lucianinsanity-only-art]

Euclideans, because I couldn't stop thinking about it

They are a little tridimensional, just very flat.

They grow an exoskeleton as they become adults, the babies are soft and start to gain their definitive shape as they mature

Their eyelids cover their mouth and nose holes too. The eye shrinks into the body slightly when eating.

They have at least two eyes, one on "the front" and one on "the back". The front being the eye that posses the mouth.

They reproduce by laying eggs that are fertilized externally. The eggs and their babies are large, the parents take care of them both. They rarely have many babies at once.

They are hermaphrodites. Some present exclusively as male or female, some as both and some change depending on different factors.

Their limbs are soft and flexible to allow movement around their surroundings. It looks a lot like swimming.

They have different patterns on their exoskeleton, but these are not visible to them.

All have the ability to change colors, most grow out of it when they grow and adults that still do it are seen as childish or immature.

[woomysans]

Concept: An alien species that can't reproduce sexually. Instead individuals come from clam-like creatures (similar to how bivalves produce pearls).

[princessmagpie]

so, like, Hork-Bajir, am I right?? 👀
