Would you like to elaborate on the tags where Rocky and Adrian watch Grace be good with pebbles and just have to mate him 👀

CW: nsfw, eggpreg / oviposition. Trans ftm Grace implied -> no explicit words for his genitals used, but it’s implied he has a vulva + vagina + uterus. MINORS DNI, STATEMENT.

Grockdrian haunts me with visions everyday tbh. Adrian is “the dad and the pet they said they didn’t want” with Grace to me

Eridians fall in love. It’s not like it used to be where it was survival of the fittest—you wanted someone who could create the best offspring. Nowadays, those things are just seen as a very attractive bonus. “Wow that Eridian is so smart/strong/etc, I’d love for them to carry my eggs” is a common fantasy. While pre-Grace Rocky and Adrian didn’t plan on raising their own pebbles anytime soon, they had their fair share of fooling around with the idea when their respective cycle rolls around.

Adrian is enamored with the idea of Rocky teaching their kids how to build and problem solve. Rocky daydreams about Adrian, his mate that’s nearly double his size, happily letting their children sit on top of his carapace as they work. And then there’s the more steamy (lavatic if you will) fantasies—Adrian’s hand pressing down on their mate’s ovipositor to help the eggs come down; teasing Adrian as they get worked up from their body preparing to lay.

Ultimately, the marble-sized eggs don’t merge and harden before getting tossed. Eridians don’t really have an attachment to them, especially mated ones that aren’t actively trying to conceive. Passing on to the next generation isn’t necessary for the species’ survival, so Rocky and Adrian get to have a little kinky fun with it

And then in comes ryland grace, who Adrian isn’t completely enamored with at first, honestly. He’s fragile and starving when he gets to Erid, and Adrian sees how much their mate has fallen for this weird, wet creature. Rocky brought him home with a courting mark on his arm and plenty of hope, but Adrian sees the condition Grace is in and prepares for their mate to be heartbroken.

Still, this human helped saved their entire planet and their mate.

Adrian will fix.

Ryland settles in and Adrian becomes the head of the human’s biodome team. The human’s species is ridiculously needy—Adrian huffs a little when they shift the in-house-rain system a few degrees for the third time that week. But it’s something new beyond waiting for answers about their star’s death, though—Grace shares with them science and computers and a new language. For the first time in many years, Adrian finds themself genuinely excited to enter their lab everyday.

They become friends. Rocky is thrilled that Adrian now comes to visit with him in the mornings beyond checking on the structural integrity of the place.

Eventually, the two of them get really close. Adrian visits Ryland beyond just checkups, and they begin to work on building a proper lab in the dome for the two of them to share. They’re both equally fascinated with each other’s planet, constantly showing the other something new. They get lost in working parallel for hours, becoming so comfortable with each other that they don’t even need to communicate.

It reminds Adrian of when they first met Rocky—an awkward and talented pretty thing with a habit of falling over.

Adrian doesn’t know when they started finding Grace pretty, but Rocky has been calling the human “Captain-Scientist-Doctor-Pretty-Ryland-Grace-Unmated” for long enough that neither of them blink an eye when it becomes “Captain-Scientist-Doctor-Pretty-Ryland-Grace-Courted-Rocky-Adrian-Offlimits.” They barely discuss it as the human’s presence in their lives becomes easy. It’s like he’s just another part of their society, like Grace was born there.

Grace getting a proper job as a teacher is the final nail in the coffin for both of them. Ryland is more than amazing with the kids—he memorizes their names beyond what he calls them in English. He puts the Eridians that are still learning to perceive 3D structures closer to the front. He never lets one of the little ones who struggles to learn the alphabet texture fall behind, going as far to design them a special bio-suit so they could enter the dome and learn one-on-one. Adrian is over the moons when he gets the bashful design request. When they bring the blueprints home to Rocky that night, their mate makes a comment about Grace raising Eridians of his own.

Something in Adrian stirs excitedly at the concept of Grace raising Eridians. Not his students, but Rocky and Adrian’s. They imagine Grace holding blue, brown, and green pebbles, the human chirping and squawking as they climb up his chest. Grace watching over the eggs carefully, using the instruments he helped design on with Adrian to make sure their internal development goes well makes them both swoon.

Grace’s internal temperature just barely matches the range of required temperatures for best clutch viability. They ponder that for a little while, something possessive and hot swelling in them at the idea of Grace walking around clearly claimed by where his two mates marked him inside and out. Grace making the strained sounds he does when exerting just for his mates to hear as he pushes down. Adrian holding the human to their front while Rocky sits between their little human’s legs, helping them pass their clutch and making sure it feels good. Maybe Adrian could reach a free arm around and play with the top of the human’s external genitalia that was as fascinating as it was terrifying—why humans evolved to have something so fragile and important on the outside they don’t know—and seeing how much their human could take, just how much they could leak.

The train of thought startles them—Grace became their mate at some point, hadn’t he? It had been months of courting with gifts ranging from food, to nesting material, to the finest jewelry Rocky could make. Adrian had built Grace an entire lab full of his favorite things. They had completely changed Grace’s name in Eridian and everyone knew that this incredibly strong, smart, and talented creature was very much claimed. The three would live the rest of their lives as a happy mated triad.

…Unbeknownst to Rocky and Adrian, Ryland Grace has zero fucking clue of this.

And Grace’s students? They think it’s hilarious.

You’ve been letting a new clutch of eggs incubate inside you for days now. It’s no longer something you can keep a secret, stomach swollen and basically bedridden. Your body had grown so heavy, the eggs occupying your every thought. Your partner marvels at your body, how much you’ve stretched to take every last one of their eggs.

They play with your hole, gently at first, stoking your hard dick between sliding their fingers inside. You’re completely dripping wet- they have no issue changing position to quickly slide their long, hard ovipositor to your desperate hole, and slam it in, hard enough to illicit a yelp from you.

Within seconds the dick- impossibly long, a huge knot at the base- was slamming against your clutch of eggs, pushing them further back in before you feel their knot being forced inside you. The second they’re entirely in you- they grab your hips, and start laying a new clutch in you.

It takes a few seconds until your body realises this isn’t something you can take, and unwillingly, your body starts to move and contract- against your owners commands, with their dick breeding you full again, your body starts to lay your eggs.

Your partner feels it immediately and pushes you down into the bed, shoving their knot as deep inside as it can go and growling, telling you it’s not time. You whimper, try to find the words to explain that it’s your body, you can’t control it- until their hand covers your mouth, leaving only enough room to breathe from your nose. Your body keeps pushing, you can’t stop it.

You’ve pushed eggs right up to the knot, now in a fight of trying to push them past while your partner keeps slamming their knot deeper inside you. Tears well in your eyes as your body keeps desperately trying to push, but each push is getting weaker and weaker. Your partner coos encouragement now as your body stops contracting and tears run down your cheeks, holding your aching stomach, your body finally realising it can’t get relief quite yet. Completely full, you have no option but to lay and take everything your partner wants to give you.

Might follow up with the laying of this, lmk if you want more:-)

what if... egg pregnancy that takes a while to actually start growing. you have an encounter with some kind of monster, and during the process they end up laying their eggs inside of you, but they're so small and it all feels so good you don't even think about it. some weeks pass, you're back home, cleaned yourself up after your little escapade- only for your belly to suddenly start rapidly swelling. you pant and moan as your belly grows, going from completely flat to full term in no time at all. the growth stops by the time you look overdue, and you try to catch your breath, only to be overcome with a strange sensation in your stomach and the feeling of something slipping down

spent last night being coached through birthing an egg by an amazing person i'm too nervous to tag lol, but it was definitely one of the best births i've had and i need to share

it was pretty late, so i only incubated the egg for a few minutes- but at one point during incubation i was told to give the smallest push i could, and it felt so intense, i could feel every inch of the egg nestled inside me and yet my push was so small it didn't move at all and only made me more desperate than i already was to start birthing

i was allowed to finally start pushing while laying on my back, but i had to keep a hand over my pussy so i could feel myself push and to keep the egg crowning without coming out. after awhile of pushing i finally felt the egg bulging my pussy, opening me up without being able to go anywhere. i stayed like that for a few minutes before i had to gently push it back inside of me

and then i was told to go on all fours (a position i hadn't even thought of trying before this person mentioned it hehe) i've never felt anything like it. the egg felt so heavy and i felt so full. pushing took so much energy i couldn't even balance on my hands and knees, i had to drop to my elbows leaving my ass in the air. i could feel the egg coming down my birth canal with every push, and eventually i got it to crown. but with the position i was in, the egg wound up slipping back in the second i took a break from pushing. this happened a lot, i probably spent at least a good five minutes crowning and feeling my pussy burn and stretch around the egg as i struggled to birth it

eventually i pushed hard, feeling the egg crowning more thoroughly than before, and for a moment it was stuck at its widest point, keeping my pussy pulled into a tight circle around it, until i managed to push hard again and i birthed the egg with an audible pop as it came out

i was sooo blissed out after it was insane <33

mmmm thinking about giant parasitic insects/insectoid aliens/dragons with tail-cocks/ovipositors. getting railed within an inch of your life by a thick, chitinous tail whose tip is much thicker than its base--only to find out why that's the case when it rams as deep into you as possible and starts laying hundreds of its baseball-sized eggs inside you.

Your eyes flutter open after waking up in the night only to immediately be met by a flashing screen on the roof above your bed, almost immediately locking your body in place before you can react.

Your mind is already groggy and unable to defend itself as the word "relax" start pulsing on the screen and of course, you obey.

Your muscles loose, you can't move your fingers or toes, and your jaw is slack with a thin trail of spit escaping from the corner.

Then, from under your bed, a tentacle approaches you. First one appendage tracing over your whole body, then two, then three, they work together to shuffle your limp body free from your pyjamas, one tentacle quickly gliding across your nipples as soon as they're exposed.

The second tends to your clit, both appendages moving in unison to milk out your pleasure as the slides delicately into your mouth, drizzling a sweet goo into your throat that only ramps up your natural reaction to the stimuli.

You manage to cum from this alone, though the only way to tell would be the wet patch in between your thighs and the internal pulse in your core, you wonder if its over but no.

Now more tentacles are coming up, some circle the leaky tips across your sensitive skin, a suction cup over each nipple, one tentacle is around your throat, squeezing just right. Your eyes have lulled back at this point, as the tentacles position your legs apart for them.

A thicker appendage enters you steadily, methodically, it is more bumpy than the other limbs around you and has almost immediately start pumping something inside with each thrust, making your stomach glow a dull pink.

Of course your clenching and stuck in perpetual orgasm the whole time, sucking mindlessly as you're fed by the tentacle in your mouth.

The appendage inside you starts quickening, the pace becoming less rhythmatic and more insatiable as it inflates inside you, causing a clear indent in your skin up to your belly button.

You hear a low growl and some deep huffs of heavy breaths from under your bed followed by a drawn out groan as the liquid pumping inside you got drastically thicker. The glow in your stomach quickly shaping the small bumps now settling inside your over stretched womb.

The next day of course, you have no memory of what happened to you. Once again your eyes flutter open, this time to the usual sunlight and birdsong. Though now you can't move out of bed for a whole new reason, your stomach and breasts have grown 5× there original size and now weigh you down, helplessly in your bed. Not to fear however, as In the corner of your eye you spot a tentacle creeping up to your mouth, ready to nurture you...

Imagining an egg that's actually made up of a cluster of eggs, the size of marbles, but slick and wet and squishy and soft. Falling apart inside you, going from one uniform shape into just an absolute mass of them. Like little fish eggs, made for quantity, having hundreds and hundreds inside you, never 100% sure if you've gotten them all out,,,,
