Chapter Text
“Alright class, time’s up! Hand in your assessment slab at the front before leaving, and I’ll see you guys next week!”
A chorus of groans fill the room, wearied and overly dramatic. I roll my eyes at the sound as I cross my arms, “If you guys had studied properly, I shouldn’t be hearing all this.”
“But Mr. Grace…” Rose whines from the left side of the class, scuttling over to my table to hand her slab in. I give her a pat on the carapace—all glittery and rose-pink colored—for reassurance.
“You’ll do well, where’s your confidence?”
She lets out a hum, half-anxious and half-proud.
More than a couple minutes pass, my classroom’s finally empty and my table’s full of stacks of slabs. Putting my hands on my hips, I stare at it.
…I’ll mark them tomorrow.
Rocky would usually accompany me back home after I’ve ended my classes. However, for the past few weeks, he’s been too busy with Adrian’s ‘Avatar’ Program to even meet up with me.
I’ve gotten used to his absence… only about three-to-four days ago. Okay, not really. It’s getting better than before, though.
I climb the stairs up to my humble abode. Once I’m getting my keys out to unlock my front door, I hear a clatter of noise behind the artificial wood. My heartbeat quickens as I insert the key into the lock, turning it as slowly and as steadily as possible.
Who could’ve snuck into the biodome? A million possibilities run through my head. Maybe it’s the wind, or a predator. Or one of those ‘Humans Out!’ protestors I’ve heard about from my students.
I brace myself before pulling the door open, and I freeze in my tracks.
There was a man: holding onto a box of… junk in front of my door as if he was busy in motion.
“...Rocky?!” His name comes out higher-pitched than expected.
“Grace! But… I thought you were supposed to end class at I:λℓpm (1:30pm)?” That familiar, long-awaited voice sounds like absolute music to my ears. Rocky’s face lights up the second he sees me.
He drops the box, which upon further inspection is full of groceries and little trinkets, with a loud thud, and before I could even process it—
He’s full-speed sprinting at me with arms outstretched.
And he scoops me up into a crushing hug. He lifts me up, and his chest presses against mine as he spins us around once—just because he can.
I’m tickled pink, grinning like a child when he tightens his embrace even more when I’m laughing in his arms.
“My Harmony Grace, I’ve missed you so-so-so much!” Rocky buries his head into my shoulder. I take in the warmth of him and snuggle in deeper.
Then, I hear footsteps coming from my kitchen. My head shoots upward and I see another human being. Or, what I thought was a human being.
“Oh right, I forgot to mention…” Rocky pulls away, “Grace, meet Adrian in their human vessel!”
They are tall—even taller than Rocky, along with a lean built body to go along with the height. Their skin was paler than Rocky’s too, with tattoos scattered all over their arms similar to his.
They adorned a long ponytail, with teal-ish highlights that follow across the length of their hair, as well as a beautiful Greek nose.
“Hello, Savior Grace. It’s been quite a long time, hasn’t it?” Adrian’s voice carried a gentle cadence, enchanting in its neutrality.
My brain short-circuits.
That’s Adrian. Rocky’s mate. The one who’s been working with Rocky for months now, the biology scientist I only ever saw as a tall, jade-like Eridian. And they’re… pretty. Like, stupidly pretty—with their long hair and those sharp features.
They smile at me—a small polite curve of their lips—and suddenly, I feel the need to sit down because what the actual fudge.
“Adrian offered to cook dinner,” Rocky tells me, his eyes gleaming. “For the three of us.”
“You didn’t tell Grace we were coming?” Adrian raises an eyebrow at him.
“I wanted to surprise him!”
Adrian offers a wave, their expression warm and open despite the intimidating height difference, They’re… elegant. Like someone carved from marble with how perfectly their features are arranged.
The tattoos coil up their neck slightly too—tiny symbols in Eridian script that I recognize from research notes.
“Rocky has been talking about you nonstop while we were running our tests together.” Adrian says, stepping forward slightly. “I underestimated how badly you’ve caught his heart in your grasp.”
Rocky immediately turns into a hue of deep scarlet at Adrian’s words, “Adrian! That’s not—” he sputters, flailing his hands in protest.
I can tell it’s true, by the way Rocky ducks his head and suddenly finds the floor to be very interesting.
My chest does that weird little flip at that information. He… talks about me? Nonstop? I open my mouth to say anything, but no words come out.
“He also mentioned the improvements you’ve suggested about our human vessels.” They add on.
Rocky perks up.
Adrian continues. “We’ve made some changes and additions to the human vessels during our test runs—so we still have some of our Eridian parts mixed into our system too.”
I stare at Rocky, wide-eyed. Then to Adrian, then back to Rocky. I feel the flush seeping in from the back of my neck.
“Rock, you told them about…?!”
“Ah–! Grace, I mean, it was research-related!” Rocky stammers.
Adrian tilts their head slightly. “...Were we not supposed to mention that part?”
Rocky groans and covers his face with both hands. Meanwhile, my entire body is burning up. I exhale sharply through my nose when I realize Rocky actually told them about the ‘research things’ we discussed while cuddling or post-sex.
He told them about me wanting to… experience Eridian intercourse while being human.
“Rocky and I modified the human vessels to attain our Eridian reproductive organs.” Adrian says so bluntly. Have they always been like this; so straightforward?
My brows shoot up to my hairline.
Fuck. Fuckfuckfuck.
Okay, so not only do I have two of the most attractive Eridians I’ve ever met in my house—towering over me…
My gaze involuntarily lowers to Rocky’s groin; I whip my head away from his direction instantly.
“I-uhh…” I tense my hands, grasping and ungrasping on nothing. I can’t find the words right now. I don’t even think there are any words I could use to describe what I’m feeling right now.
Rocky notices my glance, his cheeks darken. He looks… nervous. Or excited. I can’t really tell.
Adrian, however, just keeps talking like this is a totally normal dinner invitation. “We’ve been testing the modifications for weeks now. They’re fully functional.”
Fully functional.
I feel lightheaded.
A slow, knowing smirk spreads across Adrian’s face—something far too smug for someone so elegantly composed.
“Grace? You okay?” Rocky asks softly, reaching out to brush a thumb over my cheek. The contact makes me jolt slightly—my body reacting on pure instinct at his touch after weeks without it.
I swallow hard, my throat feels dry.
“How about this? We’ll do more catching up in the living room; Savior Grace can tell us what he’s been teaching our fellow Academy students for the past few weeks, hm?” Adrian’s unwavering tone sends a chill down my spine.
They’re definitely plotting something. I just know it.
Just before I could object to the idea, Rocky pulls me over to the living room by my arm.
I stumble slightly as he tugs me along—my brain still buffering from everything that’s been dropped on me in the span of like, five minutes.
Adrian follows behind, moving with quiet grace. They sit across from us in an armchair, legs crossed neatly at the ankles.
Rocky plops down onto the couch and pulls me into his lap like second nature. His arms wind around my waist automatically, chin resting atop my head.
“Missed you,” he murmurs again—so simple, so Rocky.
“So,” Adrian begins smoothly, “how have your classes been going?”
It’s such a normal question. Domestic, even.
Something about the way they’re looking at me—the slight tilt of their head—makes my stomach twist.
“We’ve been advancing in our syllabus for ‘Light’. We started on ‘Reflection and Refraction’ recently, actually.” I manage to say. I feel Rocky plant a kiss on my neck when I finish talking.
His kiss lingers for a second too long—suspiciously slow, like he’s savoring the taste of my skin.
Goosebumps blossom all over my body in an instant.
“Any… star students that we have to look out for?” Adrian continues, they uncross their legs as their eyes narrow in onto me. I see their gaze shift from me to Rocky behind me. Adrian gives him a wink before looking back at me.
They watch us with that calculating gaze, while their fingers tap lightly against their knee.
I’ve fallen for the trap. Like predator and prey.
“Rose,” I answer their question, I get distracted by how Rocky’s hands are roaming. One drifts up to brush over my pec while the other sneaks lower toward my waistband.
I stiffen.
They’re not being subtle at all.
Adrian watches this exchange with too much interest. Their smirk hasn’t faded at all.
I blurt out, “She’s… uh… top of the class. Very bright.”
A pause.
Then, Adrian leans forward. Just slightly, with their elbows resting on their knees.
“Grace,” they say softly—their voice like velvet now, instead of the neutral politeness—”would you be interested in seeing what Rocky and I have been working on?”
My breath hitches.
That tone. That look.
Adrian’s practically oozing seduction right now, and Rocky—traitor that he is—hasn’t stopped his wandering hands either. If anything, they’re getting bolder.
“Y-yeah, yeah.” I say weakly, not even sure what I’m agreeing to yet. Rocky nuzzles into the crook of my neck with a hum.
His fingers slip beneath fabric.
“We modified the human vessels to retain certain… Eridian functions. Would you like to see them in action?”
Rocky whispers into my ear: “Please say yes, Grace.”
“I do, yes.” My mouth moved ahead of my brain.
Adrian stands up. They don’t rush. They don’t need to. They simply glided forward, slow and deliberate. A hand meets my chin, tilting my head up to meet their gaze.
A thumb brushes my bottom lip, pressing down once.
“Could you explain more about what’s in your current syllabus to me, Mr. Grace?” Adrian’s voice wrapped around me like a snake restraining prey—it’s almost constricting.
I exhale softly, shakily. The way Adrian calls my name like that—like it’s something dirty—sends a jolt straight to my dick. Rocky, still clinging to me from behind, grinds his hips against my ass lightly.
A tease.
Adrian’s thumb presses harder on my lip before sliding into my mouth—just the tip at first, testing.
“Mmh…” I hum around it unthinkingly. I try to focus on Adrian’s question but it’s impossible when Rocky starts teasing a nipple between his fingers.
“Light—refraction,” I stammer out like an idiot. “Bending through mediums.”
“Mh, continue.” Adrian lets out a low sound and leans down until their lips hover just above mine.
“Light– It bends around… objects–” My voice cracks when I feel Rocky’s hardness suddenly squirm.
My heart skips a beat.
I feel it move again. It doesn’t feel like anything I’ve felt from him before. It feels like a… a tentacle?
My eyes widen.
An ovipositor.
The shape against my ass is unmistakable. The thick, tapered base of an ovipositor pressing through Rocky’s pants. Adrian’s still so close, their breath mingling with mine.
They want me to acknowledge it. To react.
Rocky whines into my shoulder blade. “Grace… please.” The tip of Rocky’s ovipositor presses against my thigh through his pants. It twitches once—curious—before nudging higher.
Adrian watches me with rapt attention, their own clothed bulge is visibly thick between their legs now too.
“Keep talking.” Adrian mumbles, then finally closes the distance to kiss me.
“I– I can’t—”
“Yes you can,” they cut me off, “it’s not that difficult.”
Adrian’s lips are warm—softer than I had expected. Their kiss is slow, coaxing, but firm enough to make my head spin.
Rocky whines behind me again, and finally shoves his ovipositor forward properly—pressing it between my thighs with a wet heat even through fabric.
I gasp into Adrian’s mouth.
They swallow the sound greedily.
Rocky’s ovipositor drags upward deliberately, rubbing over my trapped dick through my pants.
Adrian pulls back just enough to nip at my bottom lip. “Refraction,” they prompt again—demanding I answer while kissing them.
“Light. T’changes direction,” I mumble on Adrian’s lips as I squirm when Rocky presses down on my erection. “M’passes between materials. S-Speed changes—”
Rocky groans at the way I’m stammering through my explanation—obviously turned on by how flustered I am.
Adrian licks into my mouth, swallowing every broken word. Their hands grip my hips to keep me still while Rocky starts grinding his ovipositor against me in slow, filthy rolls.
“Good boy,” they purr between kisses, their hands moving behind me to undo Rocky’s slacks with surprising ease.
Rocky adds his own praise with a breathy “So smart,” against my neck that makes my brain melt—being kissed stupid by Adrian while he works me up through friction alone.
Adrian pushes the fabric of Rocky’s pants down just enough to free his ovipositor. The moment it springs out, hot and slick with pre-cum, they guide it between my thighs—pressing the thick tip right against my leaking dick.
Rocky shudders behind me, “F-Fuck–” and I whimper as the broad head drags over my length. He doesn’t waste time—he spits into his palm and starts stroking himself lazily, nudging against my clothed erection.
Adrian watches with half-lidded eyes before suddenly pinning me back onto Rocky by my throat—not to hurt but to dominate.
“Do you enjoy being trapped like this, Mr. Grace? We could eat you right up if we wanted to now.” Adrian’s palm presses harder against my windpipe. “Tell me—is this a test of trust, or a test of tolerance?”
The pressure on my throat makes me dizzy—deliciously so.
Adrian’s question hangs in the air, I can’t form words. Not with Rocky’s ovipositor sliding between my legs now, the slick tip catching on fabric.
Rocky pants against my back, “Grace, answer them.”
I swallow hard under Adrian’s grip and croak out: “B-Both. I can handle it,” I rasp out, gaze flickering back and forth.
“Please.”
Adrian smiles. “Such a polite little thing."
Rocky whimpers beneath me, dripping.
Then, Adrian releases me—only to yank Rocky up by the hair and crash their mouths together in front of me.
