It hadn't really come as a surprise when Grace had asked him. He was a scientist after all, and what scientist would ever say no to a chance to study something like this? Rocky was happy to help, especially when he had seen how excited Grace had been about it.
Even Simon, ever the stoic type, had shown some curiosity when they had discussed the subject. Rocky found that amusing, if not a little sexy.
The process wasn't too difficult. All it had taken to start the transition, was stimulation of his g-spot multiple times over several days along with some brooding of a xenonite egg that he had built and then carried around close to his body. The first part he had gotten help with from both of his mates and when they were not available, he had used a selfmade toy.
He knew the transition had begun when he had started cramping for a couple days in a row and clear liquid would spontaneously begin running down the inside of his thighs every now and then. He wasn't embarrassed about it, it was very normal for his kind after all.
Now it had been about a month.
Rocky stood in the shower, head lowered and forehead against the wet wall as the water rained down on his naked body and slow, deep breaths left his lips. His legs trembled slightly under him and his nails slowly scraped down the wall as he shuddered from the overwhelming heat inside his body. It ached. Craved. And the strings of clear slick between his thighs, revealed just how much.
He let out a bothered sigh, annoyed at how unbearable the sensation was. Obviously he'd been horny before but this was on a whole different level. It felt like he might actually die or go insane if he didn't soon fill out the bothersome emptiness inside.
He let one hand slowly slide down his own chest, over his abs and his fingertips trailed through the very slight trail of fuzz running down his lower stomach. It had lessened since he transitioned and there was barely any hair there anymore. Same with his stubble. It was still there, but it was just less prominent than before.
On unsteady feet he followed the plexiglass wall to the opening and reached out of the shower, feeling around on the floor till his hand found what it was searching for. He grabbed it and pulled it into the shower. A black, xenonite toy. It was about seven inches long and had a rounded, smooth tip while the shaft was slightly S curved. It looked like the human made g spot toys that he had seen when he had looked up such things on one of their laptops.
He shifted and turned his back against the wall underneath the shower head, slowly sliding down till he was sitting on the floor. He leant back against the wall and spread his legs out wide, gritting his teeth when he saw the amount of clear slick being washed off his inner thighs by the warm water.
" This is ridiculous.. " He murmured under his breath as he aligned the toy with the plump, swollen slit between his legs.
During the transition, his cock had slowly retreated back inside and shrunken to barely bigger than a thumb, hidden within the top of the slit. It was still as sensitive as before, though.
All that was visible from the outside now was the entire length of the slit, not too dissimilar to a human female, just longer.
Rocky groaned a bit when another surge of heat rushed through his body and straight to his cunt and he watched as it twitched and another dribble of slick leaked out and got immediately washed away by the water.
" Fuck... " He exhaled as he pushed the tip of the toy against the taut slit until it slipped inside. His hips twitched and squirmed a little as he did and he let out a half-pleased, half-annoyed sigh before shoving half of it inside in a smooth, slick thrust.
His head jerked back against the wall with a groan and his hand continued moving, wrist skillfully rolling and thrusting the smooth plaything in and out of the slit while his thighs trembled and hips rolled in time with every thrust.
Needy whimpers and cooing sounds started playing from his throat and lips but he quickly realized it wouldn't be enough. Nowhere near enough. There wasn't enough pressure. All it did was make him more horny, if that was even possible.
Frustrated, he tossed the toy aside and winced a bit, his breathing fast and frantic. He stood up on shaky legs and turned around to shut off the water before stumbling to the steps of the tub and getting out, water dripping off his soaked body along with the thicker liquid running down his inner thighs.
He reached for his towel and grabbed it, pulling it over his head to dry off the dark gray locks till they no longer dripped water. Then he dried his body, the sensation of the soft fabric sending shivers and goosebumps over his skin. He hummed to himself, trying to distract his mind but to no avail. He could only think about one thing.
After drying off, he wrapped the towel around his waist tightly to make sure it would stay there and he marched out of the bathroom. He stopped inside the dormitory, eyes flicking around at the plain boring beds and white interior. No. That wouldn't work. The beds would be a hassle. Too easy to fall out of.
He walked up to his own bed and grabbed the mattress, swiftly yanking it off the bed with ease. He dragged it to the corner of the room, pushing it against the walls before going back for a second mattress, this one from Grace's bed. He dragged it to the corner as well, placing it side by side with the other so there was a wide, soft bed on the floor.
Then he went for their blankets and pillows, gathering them up in his arms and carrying them over to the nest. He threw them onto the mattresses, piling them up against the walls slightly before walking over to grab Grace's beloved quilt. As he carried it over, he held it up to his face and took in the sweet scent. The faint scent of sweat and Grace's musk made his breath stutter and his eyes fall closed.
He hesitated by the foot of the nest before slowly spreading out the quilt over the mattresses, then looked at his work proudly.
Rocky turned around and began walking out of the dormitory, heart beginning to beat faster and faster the closer he got to the lab. The stronger he could hear the heartbeats of his two mates inside, the more his skin flushed and felt hotter than normal. He let out a shaky sigh as he rounded the corner to the lab, pace quickening as he walked inside, almost sprinting at the end.
His eyes immediately focused and locked on the two of them as his legs subconsciously moved him towards them. He looked almost entranced, mind stuck on one single need.
Grace heard the Eridian's fast footsteps and lifted his face from his laptop curiously, sitting in a shrimp like posture, hunched forward with one leg up on the chair, glasses crooked on his face.
He turned his head to look at Rocky when the man stopped next to him, only wearing the damp towel... Oh.
Grace's blue eyes widened and his face immediately flushed as his eyes lingered on the man's waist for a second longer than he had intended. He looked up to meet his face instead.
" Oh... wow- uh h-hi Rock, you alright ? You're breathing kinda heavy - " He started, but was cut off when Rocky grabbed his arm and tugged him up to his feet.
Grace followed the tug and stood up, facing the slightly taller male as he looked him in the eyes, a befuddled expression on the scientist's face.
Rocky took deep, self calming breaths that failed miserably, almost unable to control himself while Grace stood so close to him. He wanted to just grab him and push him down onto the table and have him right there, on top of papers and laptops and whatever other knickknacks were on there and with Simon right there to watch.
No.. he didn't want to freak them out. He HAD to control himself.
Rocky swallowed hard and smiled nervously, his lips quivering ever so slightly which Grace noticed, a concerned expression forming on his face as he reached a hand up to correct his crooked glasses.
" Rocky ? Are you okay ? " He asked again and the Eridian hummed desperately before speaking, voice trembling.
" Need... help. Transition done, statement. " He said, words slurring on his tongue from the amount of saliva in his mouth. He stepped back and turned around, hand still holding onto Grace's arm and he began pulling him along as he started walking towards the exit of the lab.
Grace looked surprised, eyes widening a little before sparkling somewhat with excitement. He followed along without question but they both heard Simon's voice exclaim behind them.
" Um ?? Should I be concerned or.. ? " He asked and Rocky shot him a glance and a smile, shaking his head.
" Will come get you later... " He purred and Simon's eyes widened in response. He watched them leave, too stunned to respond.
Rocky pulled Grace along down the halls, still purring deep in his chest. The blonde stumbled after him, looking blissfully unaware of where this was all going. He noticed a shiny trail of clear drops on the floor under them, realizing they were coming from under Rocky's towel. His face immediately heated up and turned even redder as he realized why.
" Oh.. wow. So - you're finally fully transitioned? Oh I can't wait to examine - " He began happily but Rocky cut him off, smiling.
" You can do that later... " Rocky said, fingers squeezing the blonde's arm softly.
He pulled him into the dormitory, swiftly turning the dial by the door to lower the lights down to a pleasant, half dark luminosity as he walked through the doorway. Grace watched and then saw the stripped beds, tilting his head curiously before his eyes fell on the nest of mattresses, pillows and blankets in the corner.
He felt his stomach flutter a little as the pieces slowly fell into place in his mind.
Rocky stopped at the foot of the nest and turned to face the blonde, head tilted to the side slightly. His arms wrapped around Grace's waist and pulled him close and Grace gave in, putting his hands on the Eridian's chest as they looked at each other, exchanging unspoken words for a moment before Rocky leant in close to the blonde's flushed face.
" Grace.. " he whispered against his lips, fingers curling under the man's shirt and slowly snaking up his bare back underneath, making him shiver.
Grace swallowed hard and wet his lips softly before going in for the kiss, head tilted for better access as the kiss immediately turned deep and passionate and Rocky reciprocated with a deep hum of lust, eyes staring intensely into the blues of his mate while their tongues fought and danced against each other.
Grace's hands slowly slipped from the other's chest and slipped down to grab his waist instead, holding him close while he enjoyed the feeling of Rocky's nails slowly grazing down his back with so much need and unspoken pleading that Grace felt his heart skip a beat.
Their lips broke away from each other, tongues still connected messily in the space between while both breathed out shaky sighs, then let their lips return together. A small whimper left Rocky's throat and when Grace heard the sound, his eyes widened a tiny bit.
He slowly broke away and moved one hand up to cup the side of the older man's neck, looking at his surprisingly flustered face.
" Hey, what's going on with you.. " the scientist asked gently and Rocky licked his own glistening lips without breaking eye contact, savoring the taste of him that still lingered.
" Body has gone into heat... It's unbearable. Grace help me, question ? " Rocky half whispered, half sighed as his eyes fell near closed.
Grace listened and felt his stomach flip a little at the word Heat. Indecent thoughts started teasing him in his mind but he tried to stay professional about it so he cleared his throat a little.
" Oh... s-shoot, right so how can I help you ? " He asked innocently despite deep down knowing the answer. And he thought correctly as Rocky took a step back, quivering hands leaving the blonde's body and instead slid over his own bare chest and stomach sensually. He grinned wide but his brows furrowed down and his eyes were desperate as he spoke.
" Need you to fuck me... Please. " He said and watched as Grace's jaw fell slack, staring at him in disbelief. The blonde's face turned red to the point that even his ears and chest had changed color and Rocky loved it. He found it absolutely adorable.
The scientist stuttered out some incoherent nonsense before gathering his thoughts enough to speak properly again.
" I- but- o-oh man... I don't k-know if- I could- but... I've only ever b-been with a woman once, l-like way back in college and I was drunk so- I'm- I don't think I'm good enough Rock, y-you're married and all I mean- oh gosh - ... "
He babbled on, going on another one of his nervous tangents while Rocky just watched him, grin still on his lips. He slowly stepped forward again while the blonde still spoke and before he could protest, Rocky had scooped Grace up in his arms and lowered him down onto the nest of mattresses and pillows. He placed him on his back and slowly leant down over him, catching his lips in another deep but more sloppy kiss that stopped the man's rambling.
Grace gasped but kissed back, unable to resist the super heated lips and skillful tongue. It was intoxicating. He shut his eyes tightly, face still hot and red as he thought about what Rocky had asked him to do.
Could he do it? It wasn't that he didn't want to. Oh god he wanted to but he was genuinely too insecure and worried that he wouldn't be able to satisfy the Eridian, and that anxiety was keeping him soft and his body tense.
Rocky could tell. And he found it amusing. He was gonna have him one way or another, so he decided to take it into his own hands.
He slowly broke the kiss, licking across the blonde's lower lip playfully while he purred and cooed to him, watching how his blue eyes shyly opened to meet with his.
Rocky began planting wet kisses down over the scruffy blonde beard, over his jaw and then down his neck, licking a hot streak over the skin every couple kisses as he made his way down lower and lower. His hands found the hem of his shirt and he lifted it up with a chuckle as Grace helped take it off without question.
" Just lay there and look pretty for me, Grace ~ " Rocky hummed before licking down the middle of his abs, to his navel, dipping his tongue into the small hollow. Grace's stomach squirmed a little and his back arched, pressing his belly up against the other's face and a small groan left his lips.
" R-Rocky... " Grace whimpered, one hand by his own face, cupping his own burning hot cheek while his other hand gripped at the blanket under them.
Rocky hummed against his stomach, smiling teasingly as he kept crawling lower. His fingers trailed down the blonde's sides and gripped the waistband of his sweatpants while he slowly nibbled at the fabric. He could tell he wasn't hard yet but that wasn't gonna stop him.
He purred and slowly pulled the soft fabric down, reaching a hand under Grace's leg to lift it so he could pull it down to his knees, then he did the same thing with his boxers. Once he had gotten the bothersome clothes out of the way, he slowly laid down on his side, between the blonde's legs, resting his head on the scientist's thigh as he looked at his soft member with hungry eyes.
His gaze flicked up to meet with the blues of Grace who watched him with a shy, anticipating look that made Rocky chuckle.
" Beautiful.. " Rocky hummed, smiling at him lovingly before he looked back down at the task at hand. With one hand on Grace's thigh, he leant in and grabbed his soft length with his other hand before slowly pressing his tongue against the shaft, holding it there to let the heat and wetness soak in, earning him a small whimper from Grace.
He let out a small cooing sound again, sultry eyes rising to lock with Grace's as he slowly took him into his mouth and started sucking and licking in an agonizingly slow pace, barely even moving his head at all. He hummed deeply while he worked him hard, vibrations shooting through Grace's spine and through his lower stomach as the well known pressure and heat began to appear and blood started rushing south.
Grace watched him, enamored by the sight of Rocky splayed out between his legs like that with his cock in his mouth and his chin and nose pressed against his groin.
He felt embarrassed, but he couldn't look away. It was like Rocky's eyes had locked his own in place and he didn't dare look away in case this was all just a lovely dream and he'd slip away and wake up all hot and bothered.
" Ah..hnn.. god, Rocky you're.. " Grace breathed, lips parted as a shaky exhale left them. " So sexy.. " he continued, voice breaking into a small moan at the end.
The Eridian purred in acknowledgment, then winked at him before he began suddenly bobbing his head fast, feeling how Grace was already half hard inside his mouth and throat. He still didn't break the eye contact, revelling in Grace's expression and how it changed the second he began actually blowing him properly. He loved how the blonde's eyes crossed somewhat, how he bit his teeth together hard and how his head tipped back ever so slightly.
His gorgeous, adorable alien mate. Oh how his chest swelled with love and his cunt ached and stomach tightened with lust.
Rocky hummed louder, upping the intensity of the vibrations while he sloppily bobbed his head up and down, sucking and licking over the underside of the shaft with every headbob and feeling him grow harder by the second. He felt the twitches and the veins begin to bulge, pumped full of blood.
Grace's breathing was quickening and he was beginning to struggle with keeping the eye contact as his eyes almost rolled back from pleasure. One of his hands slowly slid down the mattress and found its way subconsciously into Rocky's gray wavy hair, earning him a moan from the Eridian around his cock.
" H-hah..n..nn- fuu.. R-Rocky... "
The older man cooed again, finally tasting the salty flavor of pre-cum on his tongue so he slowed down the relentless pace and instead just slowly pushed him into his near burning hot throat instead, holding him there for several seconds before he pulled back with a wet, slick sound as his lips suckled saliva off the tip and he lifted his head off his groin, watching how his cock stood hard against his lower stomach now.
He smirked proudly and raised an eyebrow before looking up at the blonde's face, watching him slowly come down from the high and meet his gaze again.
Grace breathed slow and heavy, eyes already blissed out somewhat and he swallowed hard, his hand still resting on Rocky's head.
" Hey I- hah.. I want to return the f-favor.. " he panted out and saw how Rocky's eyes lit up before he sat up on his knees. He watched the Eridian slowly run his hands down his own well muscled torso till his fingers gripped the edge of the towel still wrapped around his waist.
" Mmn.. please do. " Rocky purred, smile undeniably excited as he tugged the towel down and tossed it aside, off the nest. He sat there on his knees, fully revealed for the first time to Grace who stared in awe.
Grace looked over his lower stomach, eyes trailing over the turquoise piercing that usually sat right above his cock, but now it just decorated the flat skin above a plump, taut slit that ran down between his legs, to the perineum. A single opening, like Rocky had explained when they once examined him and Grace had asked about their reproductive anatomy while he was still in his ' male - mode '. This was the opposite. This was the ' female - mode ' as they had decided to call it.
Grace saw the absolutely obscene amount of clear slick that decorated all of the inside of Rocky's thighs. So much that it was stringing between his legs in places, dripping down onto the mattress underneath. He felt his mouth water and his gut tighten harshly from pure, primal instinct. His cock twitched and dribbled a bit more pre-cum in response.
" Oh... My god. " Grace exhaled, slack jawed and almost drooling at the sight. He loved Rocky's cock but this was lewd on a whole different level and was doing something unholy to his brain.
Rocky chuckled and lifted his arms above his head, stretching them slowly and sensually, muscles flexing.
" Not god, just me. " He purred.
He reached down and grabbed the stunned scientist's hips, yanking him down slightly so that Grace fell down flat on his back with a small gasp. He then leant down and slowly crawled over him on all fours, till he straddled Grace's chest, knees on each side of him.
Grace's gaze was transfixed on the heat between the other's legs and his eyes almost sparkled from excitement. His hands somewhat mindlessly came up and placed themselves firmly on Rocky's hips, trying to pull him closer eagerly but Rocky didn't let him. He just sat down on his chest instead, not putting his full weight down but just slowly grinded against his chest, wet thighs rubbing against the blonde's ribs.
" Mnn never done this either, question ? " Rocky hummed, tilting his head as he watched the man stare at him hungrily. He saw Grace shake his head and it made him laugh softly. He reached a hand down and grabbed the other's glasses, gently taking them off and placing them a bit away so they wouldn't get damaged. Then he smiled and gave another roll of his hips against Grace's chest, feeling how he once again pulled on his hips.
Rocky sighed shakily, wanting to tease him some more but fuck, he couldn't wait any longer. He felt like he was burning up on the inside.
When Grace tugged eagerly again, he finally gave in and shuffled forward some more on his knees till he straddled the scientist's face, hovering just above it. He could feel the hot, anticipating breaths hit his slit and he almost doubled over from the electric pleasure that shot through his stomach.
His hands slipped down and ran through the younger male's dusty blonde hair, fingertips caressing over his scalp and in return he felt how Grace's fingertips dug into his hips.
" Nice and slow mnn.. good good Grace ~ " he cooed before slowly lowering his hips down till he felt warm wet lips and tongue slip across the slit, then plunge inside him feverishly, lapping at the soft, wet flesh inside.
His thighs spasmed a bit and his head jerked back immediately, the sensation so strong that he almost got lightheaded. A long, shaky moan left his lips. A sound he rarely made. And Grace in response, groaned and hummed against his cunt, hands squeezing his hips and massaging them.
Rocky sighed deeply, eyes rolling back a little as he stared blankly up at nothing and his hips slowly rolled back and forth a tiny bit against the other's face. One of his hands let go of Grace's hair and he ran it up over his own stomach and chest with a purr, placing it on his own neck. He slowly tipped his head back down and looked down at the blonde with a smile of trembling lips and half lidded eyes so full of lust that his pupils were blown wide.
Grace met his eyes, his own dazed and full of admiration as he kept working the wet slit that grinded against his lips, tongue toying around, slipping in and out with every roll of Rocky's hips as he lapped at it with the flat of his tongue.
The Eridian tugged slightly on Grace's hair, fingers gripping the blonde locks firmly but not hard. He hummed and licked his own lips a bit, tilting his head.
" Mmnn- c-come on.. h-hah.. deeper Grace... mm.. good boy.. ' he purred out, watching how a visible shudder rippled through the blonde upon hearing the praise. He chuckled a bit and shifted down further, smothering the man's mouth and nose in his heat.
Grace groaned and whimpered a little when his hair was tugged and he heard the praise. The words went straight to his cock and he moaned when he felt the searing heat and wetness envelop the lower half of his face.
He opened his mouth as wide as he could and stuck his tongue out as much as possible, pushing his face up against the other's cunt, tongue pushing as deep inside as it could, bottoming out. He began moving his face in time with Rocky's hips, suckling and licking feverishly at the plump flesh and sweet, clear liquid streaming out from deep inside. It ran down his chin and cheeks, stringing between Rocky's groin and his face.
Rocky's eyes widened and crossed, his body jerking and shaking as white-hot pleasure surged through him like magma, melting him from the inside. He bit down on his lower lip so hard that it drew blood and the droplets of silver fell and landed on Grace's face. His moans turned melodic as he sung out several swears in Eridian, forgetting how to speak English for a moment.
" Ag - ♫ ghn ! - ♪ nn... ♬ ♩. ♫ .. "
Grace moaned continuously against him, vibrations rippling deep inside and making his insides spasm up, clenching around the male's tongue and face. Rocky twitched and his hips stuttered, face screwing up slightly at the overwhelming sensation and he swayed a little, lightheaded from the pleasure. It kept building and building, his stomach tightening more and more which was making him squirm and tighten which Grace could feel.
Grace forced his head back just enough to take in a deep, shaky breath before diving right back in hungrily, licking up from the top of the slit and up over the piercing, playing with it with the tip of his tongue. He placed a kiss on it, then licked back down to the heat and buried his mouth against it again, feeling how Rocky twitched and jerked against his mouth.
Rocky moved his free hand back down and gently wiped the drops of silver off of the scientist's face, then slipped it into Grace's hair again, holding onto his head with both hands as he began grinding his hips hard, slow at first but when Grace followed along, licking and sucking faster and faster and deeper and deeper, he subconsciously followed with his hips, speeding up more and more as well.
Grace's hands guided his hips, pulling him into each grind and he began moaning loudly into him, voice growing high pitched and needy, his moans mixing with the lewd, wet sounds that were growing louder and louder.
Rocky's hips stuttered more and more, thighs straight up shaking as the coil in his stomach tightened to critical levels before snapping. He threw his head back suddenly, biting his teeth together hard enough to chip a tooth as he pushed down against the male's face with even more weight, smothering Grace in the pulsing, spasming heat as he orgasmed and cried out, voice breaking and trembling into long, high pitched musical notes.
Grace stopped moving and just let his tongue stay inside the heat, feeling how a gush of sticky, warm liquid coated his tongue and lips and how the plush insides constricted, then relaxed, then tightened again, over and over while Rocky rode it out. It went straight to his brain like pure ecstasy. Fuck he needed to be inside him like, right now !
Rocky slowly released his iron grip on the other's hair, trying to pant out an apology but no voice left his lips between his heavy breaths. He looked down at Grace, swearing he almost saw heart shapes in the blonde's eyes. He sighed shakily, pupils still blown wide.
Oh he wasn't done yet.
Grace met his eyes and waited a little before slowly moving his lips and tongue again, caressing the spasming insides soothingly until Rocky decided to lift away. But he didn't lift away. He just slowly rolled his hips again, making Grace whimper a little.
He teased him a little more before slowly lifting up his hips and shuffling back until he sat on the blonde's chest again.
Grace's tongue slipped out of him with a wet sound and he panted breathlessly with his mouth wide open and slick covered tongue hanging out like a dog, strings of the liquid connecting his mouth and face to Rocky's slit when he backed away from his face.
Grace tipped his head back a little against the mattress, enamoured eyes locked with Rocky's as he panted and slowly closed his mouth, swallowing the sweet nectar in a single gulp. Rocky watched and cooed happily, licking his own lips before he leant down on top of him, head tilted to the side playfully as he begged for a kiss and a taste.
Grace parted his lips again, inviting him in and they kissed, slow and sloppily, sharing spit and slick slowly as their tongues rubbed against each other and teeth scraped over teeth.
While they kissed, Rocky crawled back a little, till his knees were on each side of the blonde's hips. He slowly hummed against the other's lips and broke away enough to whisper.
" So good, mmn.. my Grace... Doing so good. Just enjoy yourself and look pretty for me now. " He teased, nibbling the blonde's lower lip, earning a small, needy whimper from him.
Rocky put both hands on Grace's chest and pushed himself to sit up, sitting on his lower stomach. He smiled down at his mate, half lidded eyes still as lustful as ever. He wasn't even close to being done with him and Grace felt honored and like the luckiest man in the universe. He watched blissfully as Rocky reached down, grabbing his almost painfully hard cock and holding it up before lifting up above it.
He shot Grace a mischievous smirk before slowly slipping down on his cock with ease, not breaking eye contact for even a second. It slipped inside him so easily with just how incredibly wet he was.
Grace was enveloped in sweltering hot, soaked insides, all the way to the hilt as Rocky only stopped when he was sitting flush on his lap, purring playfully when he saw Grace's body tense up and his head press back against the mattress.
He fought demons internally to not move his hips and Rocky noticed this which made him chuckle so he relaxed till his full weight pressed down on Grace's lap, pinning him down. Even if Grace tried to move his hips, he wouldn't be able to. Rocky was too heavy.
Grace groaned loudly, cock twitching and dribbling happily inside the plush, so intensely warm insides. It was almost too much. It almost felt too good.
" H-oooly s-shit... a-ahhm-my god Rocky-y-y ... " Grace winced loud and shamelessly, desperately grabbing the Eridian's hips and trying to get some kind of friction as Rocky just sat still, teasing him by just holding him so deep inside.
Rocky purred and looked down, rubbing his hands all over the man's torso, spreading the beads of sweat that had started to form in some places. He caressed all over his upper body before cupping his pecs, a wicked grin on his lips.
" Pretty p-pretty pretty... So beautiful, so good. " He teased, waiting for Grace to begin squirming under him from the praise. He slipped his hands down to Grace's stomach instead, firmly placing them there so he could brace himself. Once he knew he was ready, he began lifting his hips and weight back up, all the way till Grace's cock almost slipped out of him, then he halted for a second before slamming back down onto his lap, their hips bouncing slightly on the springy mattress.
A loud moan trembled from Grace's lips and his eyes fell almost closed, hands jerking up to grab Rocky's sides and hold onto them firmly.
Rocky smirked and began purring loudly, licking his own lips as he kept lifting up, then slamming back down on his lap several more times. He couldn't help but groan a bit, his stomach fluttering so deliciously every time.
Finally. Finally he felt full, but he wasn't satisfied yet. His body still craved more.
He slipped down on his lap again and began rolling his hips skillfully, leaning back slightly with one hand moving to grip Grace's thigh behind him for support as he grinded and rolled hard on him, gasping as he felt his cock rub against his tight insides.
He looked down and watched how his fluids pooled on Grace's groin, sticking to his inner thighs every time he moved and he listened to the wet, slick sounds that had started playing with every grind and roll of his hips.
Grace heard the sounds as well and shuddered, head tipping back and his back arching off the bed which only bore him deeper inside the Eridian, causing Rocky to moan out in surprise.
" O-oh fuck- fuu-h-haa..hnn- Rocky... Rocky-y-y - " Grace gasped out, voice breaking and hitching in his throat from his head being arched back. His fingertips curled into Rocky's sides, gripping him firmly.
Rocky hummed playfully, listening to the sweet sound of his name rolling off his mate's lips like music. It only fuelled his arousal even more so he started speeding up his grinds, then began lifting off his lap with a roll of his hips every time, properly bouncing on his cock.
" Mmnn- Good boy Grace- hah.. give me e-everything m-my Sun ~ " Rocky sang out between gasps and groans, smiling widely. He reached both hands behind himself, arching his back even more and tapped Grace's legs a few times, telling him to lift his knees.
And so Grace did, planting his feet on the mattress and lifting up his knees. The shift in angle made him moan and whimper a bit when he felt less pinned so he instinctively began thrusting his hips up in time with Rocky's movements, hips slapping against ass louder and louder the more they sped up.
Grace's eyes rolled back in his head a bit and his mouth was agape, panting and moaning in time with each thrust and Rocky sounded the same, purrs stuttering in his throat when the different angle made Grace slam straight into his g-spot every time he thrusted into him.
As lewd sounds filled the room, Grace's moans began breaking and becoming more and more high pitched as he felt his stomach tighten rapidly. His nails ran down Rocky's sides and he gripped his hips tightly, fingertips digging into his warm skin.
A deep moan erupted from Rocky's throat when Grace suddenly slammed him down onto his lap so hard that the Eridian's whole body jerked and his legs shook on each side of Grace's hips violently, muscles spasming out. He threw his head back and cried out raspily.
" Y-yes ! YE-E-S - ♫ ♩ ♬ ! ! "
Grace winced loudly and his back squirmed into the mattresses, his vision whitening out and stars pricked in front of his eyes as he came harder than he had in a long time, his cum almost reaching Rocky's womb.
He breathed in loudly through his teeth, then a deep moan hitched in his throat as he began to slowly grind his hips, riding out the orgasm, greatly helped by Rocky grinding with him.
He felt the wetness inside the Eridian overflow and leak out onto his groin and it sent a shudder through him. The heat inside him was growing. It was almost too much, bordering on the edge of too hot to be comfortable.
Rocky slowly lowered his head again to watch the spent male under him. He smiled and began leaning down on top of him, making sure to still keep Grace's now softening dick inside him.
He put his hands on the blonde's face, slowly caressing his cheeks while he kissed his chin and purred deep in his chest, but his eyes had a wicked look to them.
" My beautiful, good, perfect Grace ~ " he praised between purrs and kisses to his face.
Grace opened his eyes tiredly, meeting Rocky's gaze and smiled at him when he heard the words of affirmation. But when he saw the look in his eyes, Grace's face flushed even harder.
" R-Rocky y-you're still - " he began, voice raspy from moaning but Rocky cut him off with a grin and a kiss to the lips before sitting back up on his lap.
He reached behind to grab Grace's legs, then started grinding on his soft cock, listening to the lewd squelching sounds it made as more of the liquid and cum left him and trickled down Grace's hips.
Grace gasped and his face screwed up when Rocky began moving again, immediately feeling overstimulated and overly sensitive. It was too much. Every movement sent sparks of electricity through his spent body, making his muscles twitch and tremble.
" W-wait a-ahn-ooh fuu-ck o-h sh-i-t - "
He bit his lower lip hard, eyes rolling back and crossing as he tried to protest but no more words left his lips. Only incoherent babbles between horny, pleading moans.
Rocky watched and listened, delighted that he broke his mate completely like this. His insides twitched and tightened again, still aroused despite having already orgasmed twice. Fuck this heat was really ruining him.
He laughed breathlessly while his hips continued to roll and grind hard, smothering Grace in the wetness and heat in a truly ungodly way. Rocky didn't stop. He kept rolling his hips feverishly, trying to satisfy himself while Grace whimpered and squirmed underneath him, reduced to a sweat soaked, flushed mess.
Rocky leant down over him again and caught his moaning lips in a wet, sloppy kiss, eyes staring into Grace's near unresponsive blues as he licked and played with his mouth. He could still taste himself on the blonde's tongue. How delicious...
After several more minutes of the relentless grinding and Grace's brain having entirely checked out from overstimulation, Rocky felt him actually grow hard inside him again.
His eyes shot wide open and he grinned wickedly, immediately feeling himself almost cum yet again at the sensation. He put his hands on Grace's sweaty, heaving chest and pushed himself to sit up, immediately beginning to bounce on his lap again while a loud trill exploded from his chest.
" ♫. ♩ ! Ye-ss, haa- fuck y-yes, h-hnn yess-s Sunlight, s-so good ! Grace-e-e hnn- Gracegrace-gra-c-e ♬ ! ♪ "
Rocky straight up cried his mate's name, voice going higher pitched than ever before as his bounces began stuttering. His muscles gave in and he slammed down on the other's lap, burying his mate deep inside again as Grace miraculously came a second time, but nowhere near as much or as violently as the first time.
A full body shudder rippled through the scientist and he groaned and winced weakly, hands gripping the blanket underneath him so tight that his knuckles turned white.
Rocky panted and gasped for air, body drenched in sweat and wide eyes staring blankly up, his brain short circuiting a little from the completely overwhelming amounts of pleasure and sensitivity. A trail of steam escaped his lips as he panted, showing just how worked up he was inside, running even hotter than normal.
He just sat there, arms limply hanging down his sides and legs quivering from overexertion before he slowly slipped off Grace's lap with a wet 'schlik ', then collapsed next to him on his side.
He panted heavily, eyes blankly watching Grace who looked like he had passed out next to him so he chuckled and reached a hand out, softly caressing the blonde's cheek. He could tell from the sound of his pounding heart and his breathing that he was still awake, just completely drunk off of sex and overstimulated out of his mind.
" Thank you, beautiful mn ~ " Rocky purred, shifting closer to kiss Grace's scarred shoulder slowly.
He noticed a new sound, seconds before it happened.
A strong heartbeat. And deep, eager breathing.
Simon.
The younger male pushed open the door to the dormitory and stepped inside, dark eyes immediately locked on the two of them.
Rocky felt a shiver run down his spine when he sensed the hungry gaze that landed on him specifically. He swallowed hard and smiled wide, licking his own lips slowly as he turned his face to look up at the man towering over them at the foot of the nest.
Simon stared at them. At him. His eyes were dark and predatory almost. Needy. Rocky knew what he was in for, and he couldn't be more ready even if he tried.
He flinched when Simon reached down and carefully scooped a limp Grace up into his arms, then slowly carried him over to the one bed that still had its mattress and placed him down on it, looking him over.
" Holy shit... You really fucked his brain out of his ears this time huh. " Simon murmured, voice deep and alluring as he looked Grace over, just to make sure he was actually okay and just completely sex drunk.
Then he slowly turned around and stared at Rocky who was still on the nest, on his side but he slowly rolled onto his back instead.
Rocky sighed and stretched his muscular arms above his head slowly.
" Apology. In heat... Can't help it. " He murmured with an amused tone, sending Simon a smirk. But his face dropped a little when the younger male ominously began walking towards him while unzipping his cargo pants.
He reached into them without breaking eye contact with the Eridian and slowly grabbed and pulled out his big, stone hard mutated cock, holding it with one hand as it dripped a single bead of pre-cum.
" Well then. Maybe this can help, hm ? "
He asked as he stopped at the foot of the mattresses, towering over Rocky who grinned wide, mouth drooling almost as much as his cunt from the sight.
