Would you like to elaborate on the tags where Rocky and Adrian watch Grace be good with pebbles and just have to mate him š
CW: nsfw, eggpreg / oviposition. Trans ftm Grace implied -> no explicit words for his genitals used, but itās implied he has a vulva + vagina + uterus. MINORS DNI, STATEMENT.
Grockdrian haunts me with visions everyday tbh. Adrian is āthe dad and the pet they said they didnāt wantā with Grace to me
Eridians fall in love. Itās not like it used to be where it was survival of the fittestāyou wanted someone who could create the best offspring. Nowadays, those things are just seen as a very attractive bonus. āWow that Eridian is so smart/strong/etc, Iād love for them to carry my eggsā is a common fantasy. While pre-Grace Rocky and Adrian didnāt 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 thatās nearly double his size, happily letting their children sit on top of his carapace as they work. And then thereās the more steamy (lavatic if you will) fantasiesāAdrianās hand pressing down on their mateās 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 donāt merge and harden before getting tossed. Eridians donāt really have an attachment to them, especially mated ones that arenāt actively trying to conceive. Passing on to the next generation isnāt necessary for the speciesā survival, so Rocky and Adrian get to have a little kinky fun with it
And then in comes ryland grace, who Adrian isnāt completely enamored with at first, honestly. Heās 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 humanās biodome team. The humanās species is ridiculously needyāAdrian huffs a little when they shift the in-house-rain system a few degrees for the third time that week. But itās something new beyond waiting for answers about their starās death, thoughāGrace 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. Theyāre both equally fascinated with each otherās planet, constantly showing the other something new. They get lost in working parallel for hours, becoming so comfortable with each other that they donāt even need to communicate.
It reminds Adrian of when they first met Rockyāan awkward and talented pretty thing with a habit of falling over.
Adrian doesnāt know when they started finding Grace pretty, but Rocky has been calling the human āCaptain-Scientist-Doctor-Pretty-Ryland-Grace-Unmatedā for long enough that neither of them blink an eye when it becomes āCaptain-Scientist-Doctor-Pretty-Ryland-Grace-Courted-Rocky-Adrian-Offlimits.ā They barely discuss it as the humanās presence in their lives becomes easy. Itās like heās 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 kidsāhe 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 Adrianās. 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.
Graceās 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 humanās 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 humanās external genitalia that was as fascinating as it was terrifyingāwhy humans evolved to have something so fragile and important on the outside they donāt knowāand seeing how much their human could take, just how much they could leak.
The train of thought startles themāGrace became their mate at some point, hadnāt 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 Graceās 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.
ā¦Unbeknownst to Rocky and Adrian, Ryland Grace has zero fucking clue of this.
And Graceās students? They think itās hilarious.
