****** Sweet As Sin ******

Summary
     Rick has a sweet-tooth.
Notes
     A friend and I were talking about how Rick is always eating junk food
     and well, this is the result of that.
See the end of the work for more notes
"Morty, c'mon'ere." Rick grunted and waved his grandson over. The boy was
freshly showered and smelled faintly of pine-scented deodorant—Rick's pine-
scented deodorant. The little shit loved the lather himself in Rick's scent,
and Rick couldn't deny he the way he relished breathing Morty in, all nervous
energy and fresh shampoo and near constant fucking arousal. Like right now,
even though it was only 9 am on Saturday, Morty's underlying scent of delicious
want drifted across Rick's skin and permeated his bloodstream. He couldn't
escape the fucking kid, and he didn't want to.

The time since they started fucking was the best. They worked together better.
Morty constantly eager to please, but still the same moral-bound, tight-as-a-
wound-spring little shithead Rick was absolutely enamored with. It was
intoxicating. And the little doe-eyed fiend he was managed to soften Rick's
rough edges and sharp tongue. He wasn't as reckless. He had something gorgeous,
a beautiful creature made of glass, all to himself, that he didn't want to
jeopardize in any way.

 "W–what's up, Rick? D–Do you have any adventures planned today?" Morty leaned
over Rick's shoulder, looking down at work table, nearly empty except for a few
stray nuts and bolts, and a recently opened package of caramel candies. "Oh,
shit, Rick. I love these! C–Can I have one?"
Rick smiled indulgently and ruffled Morty’s curls. “Sure, kiddo.”
Morty bounced on the balls of his feet as he unwrapped a candy. They were those
Werther’s Originals, just a solid piece of hard caramel. Morty plopped it into
his mouth and sucked noisily around the drop. Rick saw the way he shifted the
candy around from each side of his mouth, pushing it with his little tongue and
closing his eyes at the delicious taste. Morty missed the basket and bent down,
showing off his ass as he picked up the wrapper and placed it in the garbage.
Rick suddenly got an idea.
As Morty came back toward him he grabbed the boy by his hips and balanced him
on one of his knees. Tipping Morty’s head to the side, he slanted their mouths
together and pushed his tongue inside. He shivered as the taste of his boy and
hot caramel flooded his senses. Morty sighed into the kiss and wrapped his arms
around Rick’s neck. Retreating from the mouth with one last swipe, Rick pushed
Morty onto the table, stomach-down.
Morty giggled as Rick’s hands tugged at his jeans. Reaching under the table,
Morty unbuttoned his pants, assisting Rick in his quest. As he tugged the jeans
and boxers down in one go, Rick leaned over Morty’s back and pressed his
clothed hardness against his ass.
“You wanna be filled up, baby?” Rick breathed, sucking gently on the column of
his grandson’s throat.
Morty bucked back against him, “y-yeah, Granddaddy.” He reached back and pulled
Rick’s hips tighter against him.
Rick chuckled and nipped along the shell of his ear. “I’m gonna fill you up,
baby. B-But not with that you’re thinking.” He reached to the table and grabbed
one of the candies. Unwrapping it, he pulled away from his grandson and dipped
his head down to mouth at his hole.
“R-Rick,” he moaned in both delight and mild protest, “y-y-you can’t put that
in me. I-It’ll get all melty. I-I-I just showered.”
Rick pressed his tongue against the pucker and groaned at how easily it opened
for him. “D-Don’t worry. I’m gonna clean you up afterwards.” He pulled away and
pushed the candy in. The sphincter relaxed at the intrusion then tightened back
up, sucking the caramel into its velvet canal, definitely not satisfied with
the meager size when it was accustomed to Rick’s girth.
Morty whimpered at the emptiness and Rick was quick to unwrapped six more
candies and stuff them inside him. Each time the pink hole fluttered open
eagerly then clenched closed once it had gotten past the widest part of the
candy. Rick put three in his mouth and added them in with his tongue. Rubbing
the ring of muscle, Rick paused and mused:
“H-H-How many do you think we can get in you, Morty?” He pushed his finger in
easily. The candies slipped around his finger, coated in his saliva. He used
the pad of his finger and pushed them deeper. “You’ve had two mega seeds up
there before, so I think you can take quite a few.”
“Oh, jeez, Rick, I dunno. They-I mean-they don’t really feel that good.”
“You mean they’re not big enough,” chuckled Rick.
Morty buried his head in his arms and flexed his ass. “Y-Y-Yeah.”
Rick clapped each of Morty’s cheeks, squeezing them as he pursed his lips,
“well, Morty. T-T-There’s about fifty in a bag.  A serving is three pieces, and
there’s sixteen servings in the bag. I’m not gonna wait for you to do that
math. It’s forty-eight, Morty. I had seven before you came in here wiggling
your ass like the little eager, over-sexed toy you are. You had one, so that
makes it forty. We’ve got thirty more to go, assuming the quality control at
this company is pretty good. The-urp-the only issue here is stuffing them all
inside you before they melt. So I’m gonna have to work fast. Get to unwrapping
and I’ll get to stuffing.”
Morty did as he was told and unwrapped candy after candy and handed them back
to his grandfather, who shoved one after another into his willing ass.
Around the thirtieth candy, Morty couldn’t take anymore. The candies knocked
against each other and pressed against his walls. He was stuffed so full he
wasn’t sure his grandpa could stuff more in him.
“R-R-Rick? I-I think I’m at my limit- ooh~ ” he keened as grabbed his ass and
forced him completely onto the table.
“O-On your hands and knees, Morty.”
Morty complied but his movements were slow and cautious, he was so nervous his
ass would spill out all the candies onto the floor.
“R-Rick, I-I don’t think I can keep them in.”
Rick tisked, “don’t worry, Morty, your slutty hole wouldn’t let such a good
thing go to waste.
Morty could feel them sliding around his insides. The first ones had liquified
and slicked up his channel. He really wanted the pressure relieved. It felt
like he was about to burst.
As if reading his mind, Rick pulled Morty’s cheeks apart and groaned at the
honey-colored goo seeping out of the hole. “ Fuck,  Morty, y-you should see
yourself. Leaking everywhere. God, I wish I had this much cum in me. I’d do
this to you every night.” Rick ran his tongue over the sugary caramel dripping
down and growled. “Oh my, God, Morty. S-S-Somehow your ass made them taste even
better. I-I-I don’t think I’ll ever be able to eat caramel again unless it’s
dripping from your hole.”
Morty moaned and pressed his ass against Rick’s face, encouraging him. His cock
sat heavily between his legs, dripping pre and painfully neglected.
“P-P-Please, Rick,” Morty begged.
Smirking, Rick reached between the kid’s thighs and lazily fisted his cock.
“Gotta wait for them all to melt, baby. T-Then I’m gonna suck you all out and
lick you clean. Y-Your ass is gonna smell like caramel for the rest of the
night. Fuck, and I still have some left. ‘Cause your ass is so small it
couldn’t take it all. It’s so eager but it can only take so much. I-I-I-I don’t
know how someone who can basically engulf my dick in one motion can’t handle
more than thirty pieces of candy shoved into his ass but it’s okay, baby boy.”
Rick stroked Morty with one hand and wormed two fingers into his ass with the
other, coating them in the syrupy stickiness. “Wanna taste, babe?”
Rick didn’t wait for more to answer. He shoved two dripping fingers into
Morty’s mouth and grunted appreciatively as the boy’s hot tongue lathered his
fingers the same way they sucked his cock. Feeling nasty, Rick worked his other
fingers into the boy’s mouth and moved toward the back of his mouth, gagging
him around his hand. He released Morty’s cock, buried his face back into his
ass, slurping up the melted caramel practically spilled from his hole, and
palmed his own cock through his pants.
Morty protested as Rick withdrew his fingers. Rick unbuckled his pants and
pulled out his cock and resumed stroking himself, this time with the hand
covered in his grandson’s saliva. He continued eating his grandson out of all
the sugary goodness coating his walls and starting stroking both of them with
increasing desperation.
Morty moaned and rutted into Rick’s fist and bucked back against his tongue. As
Morty neared his orgasm Rick plunged his cock into his ass. The walls clenched
tight around him and he only needed to thrust a few times before Morty was
spasming around his cock. He jerked Morty off, drawing out his orgasm as long
as possible. He came apart after a particularly hard thrust had Morty crying
out his name. He spilled inside the boy, mixing his cum with the remnants of
whatever caramel he wasn’t able to get out. He withdrew his cock and tugged
Morty off the table. Morty sunk to his knees immediately and licked Rick’s cock
clean, taking it down to the base made easier as it softened.
Reaching around his ass, Morty buried his fingers in and scooped out his
grandfather’s spunk mixed with caramel. He leaned against the table and made a
show of licking his fingers clean, even moaning around them.
“T-Tastes really good, Grandaddy.”
Rick growled, gripped his grandson’s hair, and kissed him hungrily.
“I think I know what those fuckers were talking about when they said, ‘sweet as
sin’, Morty.”
End Notes
     Please don't do this the candies would migrate into your colon and
     compact into one solid piece and you'd probably die.
