Chapter Text
It’s going to be over in just a minute. He’s going to leave you alone if you don’t struggle. Just keep still. Morty thought trembling as the old man pulled him out of his sheets and manoeuvred him towards the wall next to his desk.
This wasn’t the first time Rick barged into his room in the middle of the night, drunk out of his mind, stumbling, slurring, reeking of whiskey or whatever concentrated alcohol he had been consuming. But only recently had it become…weird.
The first time, Rick had been sitting on his office chair, just watching. Scaring Morty shitless as he woke up to get some water.
The second time, the old man had been standing right next to his bed. Hand outstretched when Morty awoke with a scream on his lips.
The third time, Morty had awoken drowsily and gotten an eyeful of his grandfather bent over the end of the boy’s bed, eyes shut closed, cock out in the open, stroking fervently. Morty had turned away quickly only to hear Rick groan a second later and jut against the wood of his bed.
It seemed that with time, Rick increased the intensity and the frequency of his visits. Just last night, Morty had woken up because someone had been watching him and then Rick’s face had materialized in front of his foggy vision and rubbed his cheeks raw with his stubble. Then suddenly everything was tight and hot and he realised that the old man was pressing himself against his body that was frozen with fear, breathing acid down his neck, panting, groaning until after painful jerk, he let go and left him alone.
During the day, everything seemed just fine. Nothing had changed. The same banter. The same old terrifying adventures and offhanded insults. Nothing let on what Rick was doing to his grandson. Only at night, his grandfather morphed into a hungry predator. So Morty tried to convince himself that it wasn’t that bad. That his grandfather had always been a little weird, a little strange. And until now nothing really bad had happened, right?
It would be like that today too. He just had to keep still.
Rick stood there holding Morty for a moment seemingly wanting to pull back but then leaned down and pressed his mouth against his.
Eyes wide with horror, Morty struggled under his grip, trying to turn his head away.
“R-Rick. What…W-what?” Rick shut him up before he could finish his question with a finger on his plump lips.
“You’re such a good boy.” he whispered and grabbed his ass with both hands to lift him up against the wall.
The boy gasped and Rick moaned full of hungry lust as he pushed his hips between Morty’s welcoming thighs.
“R-Rick…” He pushed against the bony shoulders of his grandfather to get him off but it seemed as if he were pushing against a boulder.
“Mo-argh-rty…why won’t you let me…”, he shut himself up by biting into Morty’s earlobe.
“Please… l- let me go.” Morty squirmed at the unfamiliar touch of lips on his ear.
“Come on…” His gravelly voice urged when his firm hands dug fiercely into Morty’s soft rear, tearing at his underwear.
“I won’t take no for an answer.” He moaned against Morty’s neck grinding his longing hips on his, to Morty’s shock, growing bulge.
A wave of shame washed over him when he realised that he was getting hard at his grandfather’s ministrations.
“R-Rick. Please….no.” He was breathing erratically.
Without any regard for Morty’s pleas, Rick’s right hand disappeared inside the boy’s whitey-tighties, caressing the soft flesh and inching closer to that sweet clenched pucker until the pad of his finger was sneakily rimming his hole.
“Rick! Stooop.” Morty whined, confused by what his grandpa was doing to him. He struggled against the hard grip he had on him. “Let me g-go.”
Rick remained undeterred as if spurred on by his grandson’s desperate little attempts to get him off. The old man softly nibbled at Morty’s jaw and gradually forced the dry tip of his index finger inside.
Morty whimpered torn between wanting to explore this weird new feeling of clenching down on something and being overwhelmed by the pain that was shooting through his ass.
Using the trembling of Morty’s hips to push in further, Rick managed to get his whole finger up inside the heat of his tight little ass and could stroke at that one deliciously-sensitive spot.
He got exactly the reaction he was looking for, when Morty gasped for air and grabbed at his shoulders.
“Rick! Fuck.”
In a fit of pleasure his hips twitched against the long finger in his butt, asking for more. There was no way he could stop. No way he could escape the heat that was pooling in his crotch. Lips apart, head thrown back against the wall Morty uninhibitedly moaned his grandfather’s name as a second finger wriggled itself inside.
“You’re - you’re g-g-gonna make me come in m-my pants”, he frowned, desperately clinging to Rick’s neck and shoulders. Meanwhile the old man was continuously rubbing his own hard tent against Morty’s little prick, kissing the salty skin on his neck, leaving purple marks all over.
“Such a good little slut.” He whispered and Morty groaned; face flushed with embarrassment as a progressively growing wave of lust made him involuntarily curl his toes and...
“You came like a little whore, just with a couple of fingers up your ass.” He snickered. “Now hold on and let grandpa finish too.”
Rick took himself out of his pants, gripping Morty only with one hand, with the other he freed Morty’s spent half-hard willy from his tighty-whitey prison. White cum was slowly drying on the tip of his little cock and Morty watched Rick bite his lower lip as he wrapped his right hand around the softening flesh and pulled back the foreskin.
“Ah!” He cried out at the firm grip of his grandfather.
“Shut your trap, Morty!” He commanded breathlessly and spit down a big dollop onto both their cocks. Far too roughly and far too quickly did he force them together in his big palm, sliding his rock-hard dick up and down Morty’s shrivelling wiener.
“God Morty!” He groaned deeply, tightening his grip, fucking into his hand. And then suddenly, thick ropes of cum painted Morty’s belly as Rick came all over him, growling like a dog.
When the final high of his orgasm had dissipated, Rick let the boy sink down to his feet.
“Wa-agh-sn’t so bad now, was it?” Rick kissed the exposed skin showing through the neck of Morty’s oversized t-shirt but he could only stare at the ground, his sweaty fringe clinging to his forehead. He didn’t know how to feel about what just happened.
