Summary
     When he’d flirtatiously suggested to Rick that he wanted to top
     during sex for his birthday, Morty expected some kind of sarcastic
     remark, a quip at his age and experience before it went unaddressed
     along with many of his other more ridiculous ideas. What he hadn’t
     expected, however, was for the older man to smirk and agree without
     so much as a single teasing remark, telling the brunette to meet him
     in the elder’s bedroom sometime after dinner. In the moment, it’d
     left the teen in the yellow shirt utterly dumbfounded, staring after
     his grandpa as the scientist exited to the garage with an open mouth
     and a raging hard-on that refused to die down.
Notes
     Ahhhh, here we are again! My Muse is back bitches! I was a bit out of
     my depth with this one. I tried to make Rick a power bottom but I
     think I may have failed a bit lol Oh well! Still a bunch of smutty
     goodness! Enjoy everyone. Oh! By the way! Kudos to anybody who
     notices the pop culture reference I threw in there.
     Dedicated to the ever wonderful Squikkums who is an incredible source
     of inspiration for me and always seems to get my Muse going, no
     matter how much I'm struggling. I couldn't have done it without you,
     Squik!

As the day progressed, Morty could feel himself practically vibrating with
excitement as nervous energy coursed hot and heavy through his veins.
When he’d flirtatiously suggested to Rick that he wanted to top during sex for
his birthday, Morty expected some kind of sarcastic remark, a quip at his age
and experience before it went unaddressed along with many of his other more
ridiculous ideas. What he hadn’t expected, however, was for the older man to
smirk and agree without so much as a single teasing remark, telling the
brunette to meet him in the elder’s bedroom sometime after dinner. In the
moment, it’d left the teen in the yellow shirt utterly dumbfounded, staring
after his grandpa as the scientist exited to the garage with an open mouth and
a raging hard-on that refused to die down.
That was hours ago, and despite the fact that he’d become intimately
reaquainted with his left hand no less than four times already, Morty couldn’t
seem to get rid of the persistent erection that he’d been cursed with since
Rick agreed.
All in all, Morty was glad he didn’t have a party, glad that his parents
weren’t doing anything special for his birthday and all he’d had to put up with
was cake and presents with the family before they all went about their
individual business. Part of the teen wondered how exactly they were going to
pull it off. Normally they waited until everyone was gone if they planned to
have sex in the house and though Summer was absent, Beth and Jerry were still
there and looked as though they had no plans to leave anytime soon. Morty
didn’t think on that too much though. Considering all the things he’d seen Rick
accomplish in their time together, finding a way to make their sexual
adventures go unnoticed by two people who normally couldn’t care less seemed
like much smaller fish in comparison.
On quiet tiptoes, Morty snuck past his parent’s bedroom, trying not to alert
either of them that he’d ever left his room through their barely muffled
arguing. When they were busy shouting at each other it was more than a little
unlikely that they’d notice something as meaningless as Morty walking down the
hall, but he didn’t want to risk it, still unsure of what Rick had in store for
him. Like a ghost, the teen slipped down the stairs, expertly avoiding any and
all of the creaky steps before crossing the living room, stopping in front of
Rick’s door.
Still slightly nervous, Morty tugged at the hem of his shirt, shifting from
foot to foot before steeling his nerves and knocking quietly on the closed
surface with a whispered, “Rick?”
Almost immediately the knob turned and the door opened a crack, inviting the
teen inside. Morty pushed the door open a bit, looking in curiously before
letting out a startled yelp as a hand darted out and grasped his shirt, jerking
him inside with a less than graceful stumble.
In the dimly lit room, Rick stood less than a foot away from the younger man,
his arms crossed over his chest with a signature smirk on his lips, “Jeez
Morty, you look like a -- like a white faced little virgin. Sure you can handle
this?”
Morty blushed, looking down as he continued to fiddle with the bottom of his
favorite yellow shirt, “C’mon Rick, I-I’m just kinda nervous, y’know, it’s my
first time topping.”
Though he didn’t see it, Morty could hear the scoff from his grandfather, “It’s
not rocket surgery, Morty. Fuck, y-you’d think that you were getting ready to
perform multiple heart surgery on a -- a female Oscavarian with how anxious you
look. You ever -- ever  seen  an Oscavarian Morty? Have you? Needles for teeth,
Morty. Tentacles like you wouldn’t believe and like -- like  twelve hearts ,
Mort. You gotta -- gotta --”
Morty cut him off, his erection wilting the slightest bit from the description,
“Yeah, Rick, I get it!”
The blue haired male sneered, uncrossing his arms and turning around to fiddle
with something, “It’s just -- just sex,  Morty . You stick your dick in the
hole and pump your hips back and forth. If Jerry can figure it out, I’m sure
you’ll be fine.”
Dark green eyes barely managed not to roll in exaggeration and though Morty
wanted to make some comment about the fact that if he sucked Rick would never
let him live it down he responded instead by pulling a face, “Aww Jeez, c’mon,
I-I-I don’t wanna think about my parents doing that shit, Rick. That’s gross.”
As Rick turned back towards the teen, he raised an eyebrow in amusement,
“You’re about to f- euuurp -uck your own grandpa, and you think that  your
parents  having sex is gross? Jeez, Morty, you got some unsorted priorities.”
Without waiting for a response, Rick crossed the room and slapped a spidery
looking mechanism on the wall. Morty watched with curiosity as the contraption
stretched out six leg looking things and dug themselves into the wall. A bright
yellow light lit up the surrounding space, stretching across every single
surface present before disappearing with a cheery click, the center of the
spidery machine blinking dimly.
“Woah, Rick, w-w-what was that?”
The elder didn’t look impressed with the question, but rather than brushing it
aside like the teen expected, Rick quickly locked his bedroom door and turned
back towards his grandson, looking at him with amusement, “It’s a portable
longitudinal wave disruptor.”
The blank look on the boy’s face made Rick sigh, “A sound neutralizer, Morty.
It makes the room sound proof.  Y'know, because I-I'm sure one of us willl be
moaning like a -- like a little bitch in a few minutes, Morty. ”  
A frown captured the youth’s lips, his dark brown eyebrows pressing together,
creating a little wrinkle just above the bridge of Morty’s nose as he scowled,
crossing his arms across his chest in a mirror of Rick’s earlier pose as the
elder gave him a pointed look, but the teen said nothing. Rick flicking him
shit was nothing new, in fact, he would’ve been more surprised had it not
happened but that didn’t stop him from being the slightest bit offended. If he
had anything to say about it, Rick would be the one moaning like a bitch but
that was neither here nor there.
 “Yeah Rick, I-I get it, I’m inexperienced.”
The blue haired scientist glanced over his shoulder at his grandson with an odd
look on his face, “Is that a bit of -- a bit of defensiveness I hear there,
Morty?”
Morty said nothing, turning around and reaching behind him to grasp the back of
his collar, tugging his shirt up over his head with a practiced flourish before
dropping it carelessly on the floor. However, before the teen could turn back
around, he felt the unmistakable heat of another body behind him, pressing up
against his back. The scratchy feeling of Rick’s cyan shirt against his bare
skin made the brunette shiver, a scatter of goosebumps peppering his skin,
making his nipples perk up and get hard.
Rick would never openly apologize, it wasn’t in his nature to do so, but Morty
could tell that’s what was happening when the older man casually grasped his
waist and slid his open palms over the curve of his sides and up his torso.
Callused fingertips skimmed over the boy’s ribs, making him squirm slightly
under the ticklish ministrations but he didn’t pull away. Instead, in a
silently spoken sign of forgiveness, Morty grasped the elder’s wrist and
quickly guided it up to his pebbled nipple with a gasp, arching his back
towards the warm sensation of his grandfather’s touch.
Rick paused to pinch the sensitive nub, giving it a gentle twist, “Bold little
shit.”
To anybody that didn’t know Rick as well as the younger man, the statement
would have been perceived as one laced with annoyance but all Morty could hear
was fondness.
Morty gasped as his companion suddenly leaned down and ran a hot stripe up the
length of his neck with his tongue, another shiver going down the teen’s frame
as the damp heat was suddenly met with the cool air of Rick’s room. The
temperature difference, though not greatly different, was still a bit of a
shock and the sensation only grew when Rick latched his mouth onto Morty’s
neck, pressing hot open mouthed kisses along the brunette’s hammering pulse.
"A-are you gonna fuck me, Morty, huh? Is -- is that what you're going to do?”
Rick nipped at his lover’s darkening skin, making the youth mewl in combination
with his words, “You're gonna fuck your -- your grandpa like some sick twisted
pervert?"
Morty’s cheeks flamed, his erection coming back full force, "Y-yeah Rick,
that's what I-I'm gonna do, I'm gonna f-fuck you."
Rick released the boy’s throat and gently nipped his earlobe, his voice husky
and low, “Then fuckin’ act like it, Morty.”
Sensing that the moment of tenderness had passed for the moment, Morty spun and
took advantage of the fact that Rick was already slightly bent over to claim
his mouth in a hot and commanding kiss. Kissing was something he was used to,
something that didn’t intimidate him in the least and he accentuated that fact,
sucking teasingly on the vibrantly blue haired man’s lower lip, dragging his
teeth lightly over the soft flesh. While momentarily caught by surprise, Rick
quickly snapped out of it and giving as good as he got, darting his tongue
against the seam of Morty’s lips, demanding entrance.
Morty didn’t even dream of denying him, opening his mouth with a wanton moan as
Rick’s own tongue slipped into his mouth, dragging sensually along the
brunette’s own slick muscle. Without thinking, Morty shifted the balance,
capturing the man’s tongue and sucking shamelessly on it, moaning softly as he
felt Rick’s hands grab his hips in response.
It was passionate, hot and slick as they devoured each other's mouths before it
suddenly wasn’t enough and Morty found himself desperate to feel skin against
skin. He wanted to feel Rick’s wiry arms wrapped around him, grabbing at his
flesh and pulling him closer, wanted to feel the hot column of his lover’s cock
against his naked thigh, and he wanted it now.
Fumbling under the dazed and dopey haze of his lust fogged brain, Morty found
himself clumsily pushing the well worn lab coat from Rick’s shoulders, barely
noticing as it dropped to the floor behind his companion in a puddle of
material. Impatient hands dove up under the elder’s shirt, palms sliding over
warm skin with a moan against Rick’s mouth. Both men seemed to pull away from
each other at the same time, breathing heavily and though Rick was more
composed and in control of himself than Morty, it wasn’t by much.
But the brunette wasn’t satisfied with that space for long. He allowed it only
long enough fumble with Rick’s shirt, dragging it desperately over the old
man’s shoulders and throwing it aside before reclaiming his mouth, grabbing at
his lover’s hair and pulling him closer, gasping into his mouth as their torsos
collided. With the introduction of skin on skin, Morty could practically feel
his grandfather’s heart beat through his chest, the teen’s own heart slamming
behind his ribs, eager to meet Rick’s in the middle. Though dark and more than
a bit morbid, Morty imagined, for the briefest second, stripping away the flesh
and the muscles, removing both their ribs and allowing their hearts to beat
side by side but somehow Morty knew even that wouldn’t be enough. No matter how
close they got or how far they were buried in each other’s bodies it would
never be close enough.
As if sensing his thoughts, Rick’s lengthy fingers grabbed the waistband of the
teen’s pants and jerked him closer, grinding their covered arousals together
with a growl into the youth’s mouth before pulling away.
“If you plan to fuck me, Morty, then I better get a -- a fuckin blowjob. Down,
Morty, get on your knees for grandpa.”
Morty went down without hesitation, dropping heavily to his knees with the
barest of grunts, ignoring the fact that his knees would probably be sore later
from the abuse. Kneeling in front of Rick, his face inches away from the
undeniable bulge in the elder’s trousers, Morty felt a sense of pride, as he
always did, knowing that he was the cause. He made Rick hard, made him hot and
bothered, made the genius’ cock swell and press uncomfortably against the
inside of his trousers and the very idea that he was about to please the older
man left his mouth to water.
Rick affectionately brushed a lock of stray hair back from Morty’s forehead,
“You look so good down there, baby, bebé tan bonito.”
Morty didn’t speak anything beyond a C- level amount of Spanish, but he could
recognize the word ‘pretty’ easily enough, the foreign language in combination
with Rick’s assumed comment making the teen blush and all of a sudden, he
wanted to impress Rick. He wanted this night to stick out in the older man’s
mind for more reasons than just because Morty was the one on top for once.
Sliding his arms behind his back, Morty leaned forward and sucked the button of
the scientist’s trousers into his mouth, swirling his tongue around the cool
metal before popping it open with a well placed flick, smirking to himself as
he heard the sharp inhale above him. Looking up at his lover, Morty released
the button, brushing his tongue over it one last time before dipping his head
the slightest bit and dragging the zipper down with his teeth, leaning forward
to nuzzle his nose against the newly exposed bulge in Rick’s boxers.
“Jesus, Morty.”
It wasn’t often that the teen was able to reduce his loud mouth grandfather to
so little words, so he savored the moment by reaching up to slide his fingers
into the belt loops of Rick’s pants, dragging them down and pausing long enough
to let the older man step out of them. Faced with the thick outline of his
lover’s cock, held back by flimsy material, Morty felt his cheeks coloring, the
blush most likely going down his neck and perhaps even beginning to spread over
his chest like heavily dripped ink on parchment.
Eager lips leaned forward to press along the cotton covered length, mouthing
shamelessly at it, sliding his tongue over the fabric with a moan. Even through
his boxers, Morty could feel the heat against his tongue, could smell the scent
of arousal coming off Rick in strong waves and the teen felt dizzy and overcome
with lust. He longed to tease, to soak the material in his saliva until every
single ridge and vein was visible, even through the cotton, until it was
clinging to Rick’s cock like a second skin but he didn’t have the patience.
Morty looked up at his grandpa through thick eyelashes, staring into the
elder’s eyes as he rose up a bit and dragged his tongue along the bottom of the
older man’s abdomen, half of his tongue trailing along the waistband of Rick’s
trousers. Rick, for his part, didn’t take his eyes off of Morty for a second,
watching with they eyes of a hawk as Morty shimmied his boxers down over his
hips and dropped them around his ankles. The attention made Morty feel
powerful, made him feel more in control than he did in any other area of his
life and he couldn’t resist the temptation to tease Rick some more, leaning
forward to ghost a breath of hot air over the tip of his straining cock,
watching as an involuntary shudder went through the elder’s frame.
The teen’s lips lifted in a smirk but before his grandpa could speak up and
call him some variation of a cocky little shit, Morty leaned forward and
brushed his lips over the head of Rick’s cock, the very tip of his tongue
darting out to flick against the slit, lapping at the bitter drops of precum.
Above, Rick sucked in a sharp breath and dropped his hand down to the back of
Morty’s head, cupping his skull and applying a small amount of pressure, trying
to get the boy to continue, but the brunette wasn’t having it. He knew that the
moment he was tasked with opening Rick up and starting the process to being on
top, he could lose confidence and, for the moment, he stubbornly chose to cling
to his version of control.
Morty let Rick push his head down, but rather than taking the blue haired man’s
member into his mouth, he let Rick’s shaft glide across his cheek, smearing
precum along his skin as he dipped his head and ran the flat of his tongue over
his companion’s balls, moaning softly at the feeling of the velvet sac against
his tongue. Dexterous fingers gripped the strands of his hair so hard that it
almost hurt, but Morty ignored the tingle of his skull, content to suck each
one of Rick’s balls into his mouth, lavishing them both with individual
attention, swirling his hot tongue around each one before releasing it from his
mouth with a lewd pop.
When he was satisfied with his work, Morty turned his head to the side and
nipped the inside of his lover’s thigh before pulling back a bit and using his
hand to hold up Rick’s cock, dragging the flat of his tongue against the thick
and throbbing vein along the bottom. In the back of his mind, the teen vaguely
recognized Rick’s breathy groans of pleasure, but he wasn’t focused on that.
All the boy could focus on was the taste, the hot feel of Rick’s shaft as he
ran his tongue up and down the length of it like a melting ice lolly, flicking
his tongue against the weeping tip at the end of every stroke before pulling
all the way back. As his fingers wrapped around the base of the genius’ dick,
the youth glided the crown of Rick’s cock back and forth over the swell of
Morty’s lower lip, slicking his mouth with precum.
Rick momentarily released the teen’s hair and cupped his face, smoothing his
thumb along the boy’s cheek, “ A la mierda bebé, lo puso en su boca.  Suck it
for me, Morty.”
Despite having no clue what the older man said, Morty felt a bolt of lust flow
through him at the sound of Rick’s arousal laced tone murmuring to him in
Spanish and he could no longer deny his lover, or himself.
Mouth slick with pooling saliva, Morty covered his teeth with his lips but
pressed them tightly together before laying the unyielding tip of Rick’s cock
against his tight mouth, pushing forward and mimicking the feeling of Rick
sinking his cock into a tight hole to the best of his ability. If the gasp
above was anything to go by, Morty knew that the intention wasn’t misplaced.
The brunette swirled his tongue around the exposed crown, flicking his tongue
against spongy tip as he started to bob his head a little bit, only taking the
first inch or so into his mouth.
“Jesus, Morty, your mouth was -- was meant to be wrapped around my cock. Fuck,”
Morty glanced up at Rick, watching the older man watch him as he slid his mouth
further down, angling his head to alternate between gliding Rick’s cock against
the silky insides of his cheek and the textured roof of his mouth, “Suck it
babe,  dame fuerza.”
Morty complied, applying a bit of suction and bobbing his head up and down
Rick’s length, taking a little more of his cock into his mouth with each trip
downward until he could feel the tip brushing over the tight ring of muscle
guarding his throat. With the extent of his focus, Morty tried to relax his
muscles, to prepare for what he was about to do, but even with all of that, it
still made his eyes water when he surged forward and slid the tip of his cock
down into his throat.
Above, RIck choked out a gasp, his fingers returning to the teen’s hair,
gripping the brown strands tightly, trying to anchor himself as Morty bobbed,
taking him further and further down his throat until the teen’s nose and lips
were buried in his light blue pubes.
“Christ, Morty. H-have you been practicing? Jesus, such a good little
cocksucker for me, babe, such a good boy for grandpa.”
Morty groaned at the praise but, unable to stay down any longer, was forced to
pull off of Rick’s cock with a cough, his cheeks red, eyes watering as he drew
in deep breaths. As he prepared to go again, Morty wrapped his thin fingers
around his lover’s cock and pumped them slowly up and down the length, leaning
over to spit down the length of Rick’s shaft before diving back down, taking
the genius’ dick back between his lips. Prepared for the intrusion, Morty slid
his mouth up and down the elder’s shaft mercilessly, sliding him in and out of
his throat with minimal resistance, taking him from base to tip with every
single stroke of his mouth.
But in a burst of control, Rick used his grip on the boy’s hair to push his
mouth down, keeping him buried in his throat, “You look gorgeous down there
babe, fuckin’ beautiful Morty. Your lips are -- are all swollen from sucking me
and I can see my cock making your -- making your throat bulge. Fuck, Morty.”
Rick reached down with his free hand and wrapped his hand around Morty’s
throat, squeezing slightly as he pumped his shaft in and out of Morty’s throat
with shallow thrusts, feeling his cock sliding in and out just under his fist.
He tried to stay, to linger as long as he could, but Morty felt himself
starting to gag, his muscles gripping the elder’s cock tightly, to Rick’s
delight before Morty pulled off, gagging slightly and trying not to heave.
Rick pinched the boy’s chin between his thumb and forefinger and tilted Morty’s
face up towards him, taking in the teen’s watering eyes and his ragged breaths,
the spit slicked lips and his bright red face, “You’re such a -- such a good
boy for grandpa, Morty. My good little cockslut. C’mon.”
Morty allowed himself to be pulled to his feet and he shed his pants and boxers
with ease, kicking them over to lay with Rick’s as they both approached the
bed.
Rick looked down at him, “H-how do you wanna do this, Mort? It’s your show.”
The dark haired male blushed, looking nervously down at the floor, avoiding
Rick’s eyes as his heart slammed uncomfortably behind his chest, “O-on your
back, Rick. I want to -- to see your eyes, y’know?”
Rick scoffed but didn’t tease the teen further as he flopped onto the bed,
shoving a pillow under his hips and leaving his legs splayed open, exposing
absolutely everything to his grandson, “Sentimental little shit, grab the lube,
Morty.”
Unabashed in his nakedness, Morty looked around the room, even going as far as
to pick up Rick’s coat and rummage through the many pockets with no success
before turning back towards Rick, “Where i-is it, RIck?”
On the bed, the blue haired genius lazily fisted his cock, watching the boy
with amusement, “How -- how the fuck should I know,  Morty ? It’s probably the
last place that I threw it, you know, the last time we f- eeuuuurp -ucked.”  
Morty grumbled at the unhelpfulness of Rick’s comment before looking around
more thoroughly, searching half assed through drawers before dropping down to
the ground, letting out a victorious sound as he found the half empty bottle
under the bed. Morty snatched it up and scrambled back up onto the bed, his
anxiety practically drowning him as he laid in-between Rick’s legs, looking and
feeling more unsure with every passing second.
“Jeez Morty, calm the fuck down. No matter what, I guarantee that I-I’ve had
worse.”
That didn’t reassure the youth in any way and he expressed that by looking up
at Rick with uncertainty, his face no longer smug and cocky like he’d been
during the blowjob.
Rick signed and propped himself up on his elbows, looking down at Morty with a
look borderlining on irritation, “It’s just like when I -- when I do it to you,
Morty. Uncap the fucking tube, smear some lube on your fingers a-and open me
up.” Rick dropped heavily back down to the bed, ‘Christ Morty, you’d think you
really  were  trying to perform multiple heart surgery on a -- on an
Oscavarian.”
Not wanting to imagine the alien creature Rick described earlier, Morty did as
be was told, flicking the cap open with his thumb nail and drizzling the
slippery liquid all over two of his fingers. He used more than he probably
should have, wincing slightly as the clear substance dripped off his digits and
onto Rick’s bedspread. Morty reached out with a certain amount of hesitation
and pressed the tip of his finger against Rick’s opening, rubbing the tight
ring slowly with the pad of his finger. Beneath his touch, Morty could feel the
muscle fluttering, and remembering what he liked, Morty added a bit of
pressure, pushing forward until he breached the ring and his finger slid
inside.
At the slick velvet warmth inside of his lover’s body, Morty’s mouth formed
into a little “o” of surprise. Cautiously, ever afraid of hurting RIck, Morty
slid his finger in and out of his grandfather’s hole, his cock twitching
between his legs as he rubbed the silky inner wall, imagining what they would
feel like around his dick.
“C’mon, Morty, I-I’m not some fragile virgin like you, hurry up before -
- before I blow my fucking load.”
Morty bristled, “Alright, Rick, jeez.”
Without having to be told twice, Morty slid a second finger inside his lover,
marveling at the way his hole looked stretched around two fingers, “Yeah, Mort,
that’s good. Keep goin’.”
The teen nodded, pumping his fingers in and out of the bossy man’s entrance,
spreading his fingers uncertainly, scissoring him with all the confidence of a
beginner. It was a slow process, one that Rick endured with a certain amount of
impatience as Morty clumsily opened him, eventually getting a third finger in
and stretching him further. The elder was quiet, only giving snarky comments
and a few hints here and there, and despite being hard as a rock, Morty could
feel his confidence flagging. When he was on the receiving end, he was moaning
and pushing back against Rick’s fingers and trying to get him to hurry up, out
of his mind with lust, babbling with arousal, but his grandpa was pretty quiet.
A few moans here and there, but nothing like when they were reversed. He almost
wished that he wouldn’t have asked to top. He wanted the experience to be
pleasurable for both of them, but Rick didn’t appear to be having a good time
at all. The older man was still hard, his cock still releasing drops of precum
against his stomach, but he wasn’t a quivering mess, and that made Morty more
nervous than anything.
Feeling Rick’s growing impatience, Morty pushed all those thoughts aside and
pulled his fingers free, scooting forward as he grabbed the lube again,
applying a liberal amount to his cock and slicking himself up before
positioning the tip against his lover’s entrance.
With a look of confirmation up at his grandfather, Morty slowly started pushing
in, an unadulterated look of absolute bliss crossing his features as he sunk
further and further into his companion’s body. It was nothing like his
imagination, nothing like his own fist or even Rick’s mouth. It was all tight
heat, slick and silky walls clenched around him from every angle, impossibly
hot and as Morty felt his balls touch Rick’s skin, he had to hold himself
there, gripping the elder's thighs as the overwhelming sensations tried to
swallow him whole.
“Well, Morty?” Rick clenched his muscles around the teen’s length, drawing a
little whimper from the brunette’s lips, “Do you have the the stamina to fuck
me or are you gonna blow your -- your load?”
Morty grit his teeth, digging his fingers into Rick’s skin as he pulled his
hips back the slightest amount and pushed them forward again, sliding back into
the heat of Rick’s body with a little gasp. It was overwhelming, and he felt
like he was going to cum at any second, his heart hammering as he tried to
avoid humiliating himself, and apparently Rick wasn’t helping.
Below him the man smirked, clenching and releasing his muscles with expert
precision, rolling his hips tantalizingly in slow, deep circles as he stared up
at Morty, “Look at you, Morty, so -- so close to cumming aren’t you. Just from
being inside your -- your grandpa’s hole.”
The teen wanted to deny it, wanted to claim that he could fuck his lover right
through the mattress, but in all reality he really wasn’t so sure that he
wouldn’t explode at a moment’s notice.
“A-and you were doing so well, Morty,” Rick wiggles his hips, “Are you just
gonna leave me unsatisfied Morty? Hmm?”
It was that one little statement, that mocking tone that was only half joking
that steeled the boy like he’d never felt before. Jaw clenched, Morty swallowed
his need, thought of every unappealing thing he could, pushing his desperate
need to cum to the back of his mind and as his lover opened his mouth to say
something else, Morty pulled his hips back and slammed them forward, pulling a
startled yelp from the older man’s throat.
At first, Morty didn’t say anything, he just drove his hips forward and back,
pounding his cock in and out of his grandpa’s body at a speed he hadn’t thought
possible with how quickly he was approaching his end, but as he thought over
and over about leaving Rick unsatisfied, any and all thoughts of release fell
away. He knew that he wouldn’t cum, couldn’t cum and the boy refused to stop
until Rick was squirming with cum all over his stomach.
Even more than that though, Morty refused to cum until his grandfather did so
without a single intentional touch on to his cock.
Fingers tight just under his lover’s knees, Morty hefted them up, tossing the
Rick’s legs over his shoulders, practically bending the blue haired genius in
half as he leaned over and drove his cock home, panting alongside his lover as
drove his length in and out of the blissfully tight heat surrounding him like a
vice. On a whim, Morty shifted the slightest bit and, to his delight, realized
that he’d accidently struck Rick’s prostate when the older man cried out.
It was an intoxicating sound. When Rick was on top, he rarely ever made loud
sounds. Breathy groans and growls? Sure. Even going as far as to gasp Morty’s
name when he came, but never a full fledged cry and the very sound of it nearly
drove Morty back to the edge. It made him feel powerful, made him want to force
Rick to make it over and over again until his throat was hoarse, made his
confidence return and, in that split second, Morty felt nothing but a need to
dominate his lover and prove himself worthy.
“L-listen to you Rick,” Morty drove his hips forward, grazing the elder’s spot
again and watching him gasp and squirm, his fingers fisting in the sheets,
“Crying out like some o-old slut, just begging for my cock. What’s what y-y-you
are, isn’t it Rick? Just a needy cockslut.”
Looking him square in the eye, Morty could practically see his grandpa’s pupils
get larger and he knew that he was on the right track. There would be time
later for vanilla, for stolen moments of love filled passion but this wasn’t
one of them. This was the time for filthy words, for affectionate insults and
nasty terms of endearment, for rough and brutal sex and Morty was more than
happy to provide that.
Morty pulled his cock free with a pop and manhandled Rick onto his stomach,
hiking the elder’s hips up and shoving his knees apart before grabbing the back
of his neck and slamming the genius’ face down into the sheets, using his grip
on his neck as leverage as he slid his cock back inside, listening to the long
drawn out moan of pleasure as Rick was once again filled by his grandson.
“Yeah, who’s moaning like a bitch now?” The teen clapped an open palm down on
Rick’s asscheek, basking in the spike of lust that shot through him at the
answering gasp, “Your hole just swallows my cock, Rick. So desperate and needy
for me. You’re fucking sick, Rick, letting your grandson fuck you.”
In his overwhelming arousal, Morty’s speech impediment all but disappeared,
leaving his words spoken with authority and Rick responded, driving his hips
back eagerly as best as he could, groaning shamelessly into the sheets, the
sound muffled as Morty pushed his face further into the bedding.
“I can’t hear you, Rick, can’t hear your pretty moans through the sheets,” The
teen slid his cock out, rubbing the head against Rick’s opened hole, watching
as the muscles fluttered, clenching and trying to draw him back inside, “Maybe
you don’t want my cock that bad, maybe I should just leave you hard and
desperate like this. What do you think?”
Morty listened to Rick’s nearly inaudible babble, feeling him trying to shake
his head and the teen just smirked, summoning his inner Rick as he plunged back
inside the hot and wanton body below. Right as the teen was about to unleash
another mouthful of filthy words directed towards his grandfather, he heard
three short knocks on Rick’s bedroom door.
Below him, Morty felt his lover’s muscles tense up but the brunette couldn’t
care less. He vaguely remembered Rick locking the door and unless his whoever
was at the door started screaming bloody murder, there wasn’t a single chance
that he was stopping.
The knock came again before Beth’s voice could be heard on the other side of
the door, “Dad? Are you in there? I can’t find Morty and I was just wondering
if you guys went out on an adventure or something?”
Morty’s mouth turned up in a wicked grin before he released the back of his
lover’s neck and slid his fingers around to the front of Rick’s throat, pulling
him up flush against Morty’s chest. Their height difference was even more
prominent at this angle and, even kneeling, Morty’s face only came up to about
the middle of Rick’s neck, but that only enflamed him further. That he had this
powerful, unshakable man here with him, submitting and making all those
delicious noises just for him.
Morty squeezed his fingers around his grandfather’s neck, choking him out,
driving up into him with a slower pace but more force as he nipped at the
elder’s earlobe “Yeah, Rick, why don’t you tell her where I am? Why don’t you
tell her that I’m in here with you and you’re letting me pound my cock into
your willing hole? Huh Rick? What do you think she would do if she knew that
you were letting her son fuck your brains out?”
Beneath his hand, Morty could feel Rick’s throat working as he tried to talk,
but the brunette only squeezed harder, really making the elder work for it,
“Harder Morty, give it to me harder!  Dámelo, bebé, me coge con más fuerza, dar
a mí .”
Realizing that Rick had unintentionally slipped into spanish made Morty
redouble his efforts as he released his lover’s throat and practically threw
him forward, watching Rick pressed his palms up against the wall, his head
falling forward and his back curving at an incredibly attractive angle.
“Fuck Morty, I -- I’m gonna --” Rick’s statement choked off as a particularly
brutal thrust grazed his prostate, making the elder cry out in agonized bliss.
WIth a low groan, Morty leaned over his back, nipping at his shoulders, his
voice husky as he felt his balls start to draw up, “I hope you can cum without
a single touch to your cock, Rick, otherwise you’re gonna have to go without.”
Morty, of course, knew that he would never leave his lover unsatisfied in such
a way but the treat must have done the trick because all of a sudden Rick was
nearly hyperventilating, gasping for breath, his fingers clawing at the wall as
the muscles surrounding Morty’s cock got almost painfully tight before Rick was
screaming out, driving his hips forward as shot after shot of thick, white cum
poured from the tip of his dick, soiling the sheets below him.
That in itself was to much. Feeling Rick quaking under him, watching him come
apart so thoroughly by the teen’s own hand and having put off his orgasm for so
long, it sent him directly over the edge without even the faintest hint of
warning. Morty gripped the blue haired scientist’s hips, digging his fingers
into the lean muscles below as he drove forward, crying out Rick’s name as he
emptied his load inside of the willing body, gasping and clawing at the elder’s
skin as he fucked them both through it, the slickness of his cum only adding to
the bliss he felt.
Weak with fatigue, his muscles quivering, Morty pulled his cock free, watching
with more than a little satisfaction as Rick’s hole started winking shut,
pushing dribbles of the teen’s cum out.
Without thought, Morty rolled to the side, dropping heavily to the bed,
dragging in breath after breath as his heart continued to hammer at what seemed
like inhuman speeds inside of his chest. However, Rick wasn’t much better. he’d
flopped onto his back, not seeming to care about the mess he was laying in or
the sweat clinging to his skin.
Immediately, Morty felt his dominant streak start to melt away and all he felt
was an immense need for closeness. He just wanted to be wrapped up in Rick’s
arms, basking in their shared afterglow. And he did just that, snuggling up
against Rick and burying his head under Rick’s chin, smiling as he felt the
other man’s arms wrap around him.
“Did I, y’know, do good Rick?”
The blue haired genius snorted, running his fingers through the brunette’s dark
hair with an unseen smile, ‘Yeah, Mort. Y-you did real good. I’m proud of you,
babe. Happy birthday.”
Morty smiled against Rick’s neck, those words washing over him and soothing any
sort of uncertainty he might have felt. It was like a balm to his soul and
Morty instantly knew that he’d more than satisfied his lover, which only served
to make him feel that much more successful.
Morty couldn’t resist though, and with a cocky grin and an affectionate nuzzle
to his companion’s neck, he lifted his head looking up at Rick with a smirk,
“Good thing y-you put up that sound blocker thing Rick, y’know, since one of us
was moaning like a-a bitch.”
