Chapter Text
He’s back.
I can feel him stretched out behind me, tall and firm and so deliciously warm as he lies pressed to my back.
“Welcome back, sunshine,” human-Rocky murmurs, rubbing a warm hand up and down along my chest and stomach. He finishes with a quick pat before pushing himself up to hover over me, looking both playful and determined.
“You, uh… remember what happened last time, Rock?” I ask, and he rolls his eyes, making full use of the unfamiliar expression. I’m sure I went to bed naked, but now I’m wearing a pair of black boxer briefs and Rocky is playing with the waistband, lifting and letting the edge of the fabric snap back softly against my hip.
“Yes, can remember. But also this Grace dream,” he says, leaning to kiss just under my jaw, the gentle press of his lips making me tip my head and arch my back.
“So eager, sunshine,” Rocky says, grinning and licking his lips. “Make sense. Grace starved for touch. Now can have lots of touching in dream.” He leans to whisper in my ear. “Or maybe Grace just a little slut, question?” he adds, and I whimper in response.
He presses up onto his hands, strong, tattooed arms bracketing my shoulders as he looks down at me. I can feel the air circulating in the Hail Mary, the fan from a vent blowing a cool stream of air over my skin. It’s a good thing, because my body temperature has to be spiking. I hope the taumoeba aren’t doing any harm.
I also think it might be worth it.
“Gonna answer me, sunshine?” Rocky asks, gently gripping my chin with one hand and making me look at him.
“I’m… a little slut, yeah. Only for you.”
Rocky chuckles, dimples creasing his cheeks as he leans in to reward me with a slow, tender kiss before whispering that I’m his good little slut and that he promises to take good care of me.
I nod, dazed, as Rocky rises up onto his knees to grip the hem of his black fitted tee and pull it over his head, dropping the shirt onto the floor.
He’s fucking beautiful.
The act of stripping off his shirt mussed the wild arch of his hair, but it’s still suspended over his head, just a little less styled. I let my eyes drift down his bare, toned chest, which is covered in more intricate line tattoos, including an incredible one of his ship and the pulsar map of 40 Eridani and Tau Ceti.
I gently reach up, tracing my fingertips over the tattoos. Rocky lets me touch him with one hand, taking hold of the other and sucking two of my fingertips into his mouth.
“What do you want to do?” I ask. “You c-can have anything you want,” I add nervously. Having him real and warm and straddling me feels impossible and I need to make his dreams come true.
“Grace question is silly. You control dream,” he replies, leaning down and rolling his hips (with his hard length straining against his shorts) to make a point.
I grumble, squirming under him.
“I know, Rock, but can’t you see I want to be dominated? That means you gotta take control. Have your way with me, yeah? Maybe, uh, pin me down a little. So I can’t do anything but feel it when you touch me. When you fuck me,” I say, blushing furiously.
Rocky grins wickedly and rearranges us, nudging my thighs apart.
“Understand. Need safe word,” Rocky says, and I chuckle. Rocky had done some research, apparently.
“Centrifuge,” I say, and he nods.
“Good good. Rocky start by tasting Grace. Human tongue is fascinating organ. Want to lick all parts,” he says, and I shiver in anticipation.
“All, like- all?” I ask, and he hooks his fingers in the waistband of my underwear, working them down and off my body.
“Grace cock so pretty,” he murmurs, leaning down and kissing the underside of it - right in the spot where his own cock is pierced.
It was last time, anyway.
“Is your piercing, uh-“
“Still there, question?”
“Yeah,” I moan as Rocky gives my hard length a lick, his warm, wet tongue sliding up my cock. He wraps his lips around the tip and sucks delicately, careful to keep his teeth from scraping me.
He pops off after a few seconds of warming my cock in his mouth.
“Of course, sunshine,” he replies. “Piercing especially for Grace, to make Grace feel good - stimulate pleasure,” he says. “Want to see Grace cum all over self again. So beautiful. This time, Rocky taste that. Rocky lick up mess with human mouth.”
“Oh, fuck,” I breathe, legs twitching as Rocky starts to suck my cock. He’s a quick study, noting with care what makes me shiver with delight and leak onto his tongue. Rocky raises up for a moment, then spits a long strand of saliva down onto my swollen, aching cock. He pumps it up and down and I cry out, but I don’t say the word, so Rocky doesn’t falter. He lowers his head again and swallows around me, taking me deep into his throat. I’m gasping and panting as he urges me to fuck his mouth, tears streaming from the corners of my eyes and down to my ears as I lie there. Rocky pins my wrists to the bed with his hands and looks up at me, mouth full.
“Grace like this, question?” He asks in Eridian. The musical tones vibrate against my cock and I almost shoot my load inside him right then. I nod weakly, and he chuckles before murmuring more sweet things in Eridian, how I’m so pretty and taste so good, and how he can’t wait to fuck all my pretty holes. How he wants me to fuck his.
“Like… for real? Is that even possible? When I’m awake?”
Rocky pulls his mouth off my cock to speak English, his saliva coating it.
“Is possible. Rocky make thinner interior layer to protect Grace. Eridians have reversible organ. Soft tendril you saw also goes inside body,” he says, nudging my thighs up to lick my asshole. “Like this,” he adds, poking his tongue inside and making me groan. “Very sensitive. Will also feel good good. Grace want to fuck Rocky’s real hole, question?”
My face feels like it’s blazing, I’m blushing so hard.
“Yeah, Rock. You’re beautiful in my dream, but the real you is just as beautiful,” I reply.
“Grace always beautiful,” he whispers, then pushes my thighs up, folding me in half to expose me fully. I’m pinned and helpless under him, and when I look down, I see Rocky has a small bottle of lubricant in his hand, and he’s slicked his cock with it. His shorts are hastily tugged down, the piercing shining in the soft light of the sleeping area.
“Where did you get lube-“
“That matter, question?”
“Good point.”
“Grace get fucked now, statement,” he purrs. “Then wake up and tell Rocky all about plan to fuck Rocky hole, question?”
“Yeah, Rock. I will,” I reply, and then he’s easing his cock into me, that little piercing rubbing me the whole way in. He pushes deep, bottoming out before lacing his hands with mine and pinning them to the bed.
“Feel good, sunshine, question?” He asks, and I nod, moaning with pleasure as he rolls his hips back and slams in, the force of it shaking the bed. He pounds my ass, wet slaps echoing in the small space, and he whines praise in Eridian, telling me how good my hole feels and how he can’t wait for me to feel his hole.
I know he means his real one.
But will the real Rocky want that? This is my dream, after all.
“Focus, sunshine,” Rocky hisses, bringing me back to the moment. “Only feel. Feel cock in hole, yes, question?”
“Ye-yes,” I reply, panting.
“Good good. Kiss now,” he adds, and he manages to lean down, between my spread legs, and gives me a wet, sloppy kiss. I can taste myself in his mouth.
“Cum inside me, Rock,” I breathe, and his hips speed up until the loud, frantic slaps are the only sound in the room.
I might be screaming, but I’m not sure.
“Fuck, fuck, fuck!” I cry out, and I feel heat spilling inside me as Rocky kisses me again. There’s a puddle of cum on my stomach, too.
It seems I came completely untouched, just from his cock in my ass.
Rocky clings to me, and then he’s lapping up the mess on my stomach, but his hands feel a bit like claws, which I’m learning means I must be waking up.
“Grace not forget,” he murmurs, the smooth voice sounding a bit more synthesized as I stir.
“Uh, Rock?”
I feel his strong limbs encircling me. He’s on the bed in his suit, two claws gently stroking my back.
“Grace do much much thrashing in sleep. Then Grace penis leak lots of sticky substance. This good, question? Grace not hurt, question?”
“It was good, yeah. Had another sex dream.”
“Amaze! Tell all details,” Rocky chirps, nuzzling his carapace against my naked chest to hear about it.
I relay the story, and Rocky drums his digits thoughtfully along my hip.
“Rocky think of this layer after last sexual encounter. But not know if Grace want to put penis inside hole. Think maybe Grace grossed out.”
“Oh, no, Rock. It’s an adjustment, sure, but - now that I know it’s possible, I do want to fuck you… properly,” I reply.
Rocky chirps happily.
“Good good. Rocky work on this project and soon Grace can fuck hole. Will make just right temperature and wetness so Grace cock feel good,” he adds.
I lie back, sighing with happiness.
“Will… will Adrian mind?”
Rocky pauses.
“Adrian understand. Would do same if they meet Grace. Adrian also 🎶.”
“Don’t know what that word means,” I say, and Rocky chirp-laughs.
“Enjoy unusual sex things. Willing to experiment,” he replies.
“So… kind of freaky?”
Rocky nods his carapace.
“Yes yes. Freaky about sex. Not shy. Sometime Rocky tell stories.”
I smile, leaning down to brush my nose over the top of Rocky’s carapace. The suit is so lightweight and thin that I can feel the texture of him through it, and I press a kiss to the surface, watching with curiosity as Rocky shifts, the vents opening and closing.
“Grace kiss, question?”
“Yeah, Rock. I kissed you. Sorry, maybe I should have asked first.”
Rocky makes a content-sounding hum.
“I like,” he says, wiggling his carapace against my chest as he clings to me. “Grace mouth and lips very soft. Softer than Rocky expect,” he adds.
“Mm. Tell me a story about Adrian and this ‘freaky sex’ you’re both so into,” I say, and Rocky perks up. He leans on one arm, tapping two of his claws together thoughtfully.
“The last time happen after a very productive 🎵... special Eridian meeting,” he begins. “The hive make plan to deal with astrophage, and many Eridians celebrate. Adrian know Rocky going to leave on mission, and want to experience many new sex things together before Rocky have to go. Adrian get into big, suspended cloth, and put on show with teasing of hole. Other Eridians observe Adrian invite Rocky onto swing, and then Adrian organ descend and push into Rocky hole. Other Eridians also expose organs and touch them while watching Adrian fuck Rocky,” he says.
“So you’re both into… public sex, then?”
Rocky twiddles a claw.
“Rocky a bit shy, but Adrian make it so good that Rocky not mind audience.
“I see,” I reply, tracing absent-minded patterns across Rocky’s etched tattoos.
“Yes yes. Adrian like trying new types of sex. Would notice Grace soft holes and be eager to fuck,” he says, and I chuckle.
“So, once we get back to Erid…”
“Rocky share Grace with Adrian. Only if Grace want that.”
“Yeah, Rock. Just you and Adrian, I think. But I want to try new types of sex too.”
“Good good. Grace rest now for a while. Rocky have work to do,” he chirps, tugging the quilt over me as he hops off the bed.
I do drift off for a while (no dreams this time) before Rocky comes back holding a curious looking bag. I study the thin film, marveling at the strength of the substance despite its flexibility and softness.
“Rocky fill bag with warm lubricant that safe for Grace. Water-based and right temperature,” he adds, and I notice the clear, gooey substance on one side of the film.
“Thats really clever, Rock,” I say, smiling.
“Mm. Rocky put new layer inside hole and test it out,” he says, and I stare as Rocky goes to the airlock to make the exchange, replacing the section of his suit around his hole with the film. The pressure holds, and he pokes experimentally at his hole with one claw, making a pleased-sounding chirp as he extracts it, shiny with lube.
“Did that… feel good, Rock? Fingering your hole?” I ask, and he makes a grunting noise. “It’s okay, you can do it some more,” I urge him, and Rocky seems almost frantic as he thrusts his digits into his hole.
“Grace cock will feel even better, statement.”
I have to bite the inside of my cheek to keep from moaning. Wrapping the quilt around my shoulders, I climb off the bed and make my way to the pilot’s seat, waving for Rocky to follow. He scampers after me, a little wobbly as he makes his way through the ship in his newly-adjusted suit. My cock juts out in front of me like it knows where we’re going.
Good thing one of us does, I guess.
I climb into the chair with the blanket draped around me, sitting with my thighs spread apart.
“You still want this, Rock?” I ask, watching Rocky approach slowly, his last few steps tentative as he reaches my feet.
“Yes, want. Climb into Grace lap, question?” he asks, and I hold out my arms. He takes one of my hands to pull himself up and fffffuck it’s like hauling an anchor up from the ocean floor. I hadn’t realized just how much Rocky was compensating before to avoid putting too much weight on me.
The pilot’s seat is designed to slide and rotate on the track through the cockpit, so there’s not much to hold onto except for me (and the chair, which is mostly under me). Rocky eventually manages to grab a hold of the back of the chair and then he’s in my lap, two arms around the metal frame of the headrest. He brushes one claw against my cheek so softly I almost want to cry.
Rocky could crush me so easily. He’s being so careful not to.
“I… I love you, Rock,” I whisper, and he snuggles his carapace against my chest.
“No understand word,” he says, then chirps something in Eridian that I don’t understand and I wrap both arms around his body.
We’re quiet for a beat.
“Rocky lie just now,” he confesses. “Did understand. Rocky 🎶🎶Grace too. No, 🎶🎶feel too small of word. Rocky 🎵🎶🎶🎵Grace.”
“What’s that, Rock?”
“Love without end,” Rocky replies. “No matter what.”
“Like… unconditional love,” I say, tears welling up in my eyes. This was supposed to be fun and sexy and I’m leaking again. Stupid human emotional responses.
“Yes. Grace not need to leak. Rocky would love Grace even if they not save stars together. If just met in space by chance. Would still love funny, beautiful human.”
“You know,” I say, “humans believe sex is sometimes better when the partners share a deep emotional bond. Shall we… find out if that’s true?”
Rocky traces his claw behind my ear, the digits striking through the close-cropped hair there.
“Yes. We have sex now, statement.”
I press my lips to the top of Rocky’s carapace, slipping a hand under him where he’s hovering above my lap. The new panel Rocky installed is incredibly thin and flexible, and I run my fingertips over it.
“You like being touched there, Rock?” I ask, and he makes a low, grunting sound, wiggling the bottom of his carapace eagerly against my hand. “I’ll take that as a yes,” I add, grinning.
Rocky’s got three arms anchoring him to the chair around me, one claw cupping my face, and another arched under himself to gently grasp my cock, which has started getting hard again after my brief emotional outburst had me flagging slightly.
Hard is, of course, relative in comparison with a rock-like alien, but, you know.
He seems pleased, and it’s such a relief to be touched like this that I’m moaning and whimpering before long, too. Rocky’s opening has grown, and I can feel the warm, gooey lube as I trace it with my fingers.
“Rocky make hole n-nice and warm for Grace. Not too hot for human,” he croaks, and before I can think about it any more I’m lining myself up and Rocky is easing into position and sinking down on me and oh fuck- oh fuck-
“Grace heart beat fast fast fast. Feel good, question?”
“Yeah, Rock,” I pant. “You’re just so perfect - warm and wet and so damn snug,” I groan. “How do you feel- in- inside? Does my cock f-feel good?”
Rocky’s whole body seems to be vibrating, he’s shuddering so hard.
“Grace cock so good, statement. Different from Eridian organ. Throb with pulse and make organ very wet inside too.”
I grin, slipping my fingers between us to rub at the rim of Rocky’s hole.
“You like this too?” I ask, and Rocky’s whine rises an octave.
“Grace fuck Rocky, now now now,” he demands, and I chuckle as I thrust my hips up into him, Rocky just about wailing as my cock sinks into his body over and over. His hole is perfect; the layer added is so thin I can’t even feel it. The wet core of him is draped over and around me, and I’m panting helplessly as he squeezes - gently - with his own organ.
“Oh, Rock… if you squeeze me like that, I’m gonna cum. Gonna fill that pretty hole of yours,” I babble, and Rocky bears down on me, still careful with my delicate human flesh but hard enough to make me see stars even without the Petrova-scope.
“Yes, yes. Cum inside Rocky. Beautiful Grace. My 🎶🎶. My 🎵🎶🎶🎵.”
I howl with pleasure as I feel my balls tighten up for a moment and then I hit my peak, spilling over and over inside Rocky. More and more shoots from me, the warm, sticky substance mixing with the lube inside Rocky’s engineering feat of an interspecies condom.
“Mm… wet on Rocky side too. Leak inside from arousal,” he says, a little dazed and slow.
“Love you too, Rock,” I whisper, and I wrap the blanket around both of us. Rocky shifts just slightly, gentle and slow as he holds me inside his body.
“Rocky look this up on portable earth thinking machine. Grace like cockwarming, question?”
I can’t quite keep the surprise off my face.
“Yeah, Rock. That’s very thoughtful of you.”
“Thank. Rocky also like. Can keep Grace cock inside for longer. Connected like one being.”
“Sometimes humans like being touched or, uh, pleased while asleep, Rock. Only if they talk about it first.”
Rocky’s vents do something dramatic. He looks scandalized.
“Sex while sleeping, question? On purpose, question?”
“Yeah. If you, uh… ever see that I’m hard in bed and want to touch me or do something sexual to me… that would be okay, Rock. I’m consenting.”
“Grace very freaky.” He pauses. “Rocky like. Adrian will also like. They will fall over in shock that Grace want this.”
I chuckle, giving Rocky’s carapace another kiss.
“We’ve got some more experimenting to do first, though,” I say, nuzzling Rocky. “Like, for example, will that layer work for you to put your organ inside my hole?”
“Experiment only way to be sure,” Rocky replies.
He really is getting good at the scientific method.
