Rick is nervous, more nervous than he can ever remember feeling in the last 50 odd years. Next to him sits Summer, only four and not a care in the world, not like him. He smiles softly as she grabs his shaking hand with her own small, chubby ones and begins to play with his fingers.
“Why are you shaking, grampa?” she asks without looking up.
“I’m just n- just excited, Sumsum. Excited to meet your new brother.” Gently, Rick pries his fingers from her grasp and wraps his own hand around one of hers, giving a comforting squeeze that was meant more for him than her.
“I don’t want a brother,” Summer sulks, sticking out her bottom lip in an adorable pout. Rick leans over and kisses the top of her head, his next words muffled in her hair.
“You’ll love him sweetheart, I just know it.”
The sound of a car pulling up interrupts the two. Rick shoots up from the couch and very nearly sprints over to the front door, more eager than he thinks a normal person should be to meet his new grandson. His Morty. The front door opens and Beth and Jerry try to hide their surprise over Ricks sudden appearance. He’s smiling wider than either have ever seen before, it looks almost psychotic.
“Do yo-,” Rick starts, his words faltering in his throat once he sees the mass of blankets in Beth’s arms that most definitely contain his grandson. He wants to reach out and take him, just to hold him, but Rick knows better. Beth looks to Jerry then to past Rick, and he gets the idea, going into the house to put away the items he had brought in from their car. This left Beth and Rick mostly alone, save for the likely sleeping baby in Beth’s arms. A tense silence hung over the two for a beat, passing as Beth moves the blankets to reveal her new son to her father.
All at once, Rick’s heart hammers in his chest, his stomach drops and butterflies infest his gut as he sees his Morty for the very first time. He’s beautiful. More beautiful than Summer or Beth had been as babies, maybe even more beautiful than Diane ever was as an adult. It makes Rick happy and slightly sick at the same time, sick because he knows, deep down, that he does not think Morty is beautiful in the way a grandfather should.
“Can I ha-h-hold him?” he asks, holding out his arms as if he already knows the answer. Beth, of course, nods. Why wouldn’t she? There would be no way for her to tell that there was a quickly growing darkness in her father’s heart and mind. Gently, she places Morty in Rick’s hands, careful not to wake him.
In his arms, Morty feels… right, like he is meant to be there and Rick almost hates the feeling. With one arm all that he needs to hold the boy, Rick uses his free hand to gently caress Morty’s soft face, all the while feelings that bubbling darkness spread even more within himself.
“Oh Morty, you…” Rick holds Morty close to him.
You are mine.

A month passes and Rick spends every moment he can around Morty. Beth might have been concerned with just how much attention that her father seems to be giving him, but the jealousy over said attention is just too hard for her to look past to see the disturbing truth. Rick, on the other hand, seems oblivious to all that isn’t Morty. If it isn’t with, about or anything to do with Morty, he doesn’t care. Any moment he spends away from Morty is spent thinking about or, in recent and definitely concerning developments, jacking off to Morty.
It should make him sick, sometimes it does, but Rick is quickly becoming tired of constantly mentally fighting himself over his feelings towards his grandson. It’s wrong, he knows it, but he never actually intends on doing anything about it, so why not just embrace the feelings, that’s what he tells himself anyways, that he is strong and can resist the dark urges to just ravage the baby.
Being alone with Morty really doesn’t help, but he doesn’t care, he needs to be around his baby boy. Changing Morty’s diaper is his most commonly found excuse at the moment, neither Beth or Jerry object to Rick’s willingness to do such a task having already had quite their fill with Summer a few years prior. He uses the minutes alone with Morty to stare at his little body, admiring all the soft curves, all the baby fat in all the right places, and best of all, Mortys little chubby cock. He wishes so badly to grab the boy and start licking him all over, sucking on his little cock and nipples. In his twisted thoughts, he thinks maybe Morty would enjoy it even though he knows logically that it would be years before Morty could even get hard, let alone even begin to enjoy getting fuck- no.. getting raped by his grandfather.
In the end, Rick reluctantly will close the diaper to stop himself from losing control, hand Morty back to Beth then disappear into his room to jack off to thoughts of the boy.

Another month passes by and Rick has not gotten any better, only worse. It's becoming harder and harder for him to hold back from touching Morty, often finding himself getting close while spacing out only to come back to reality and pull his hands away, face burning hot while Morty stares at him all cute and innocent like. It doesn’t help that Morty has started to recognise and remember him, getting excited every time he sees Rick. It fills Rick’s heart with joy and dread. He wonders how Morty would react if he.. no, he shouldn’t even entertain the idea, Morty is a baby, a small and fragile baby. He shouldn’t have to suffer because of Rick's disgusting desires.
But what if he didn’t suffer?
Rick sighs and pushes away the thoughts, instead focusing on Morty in his lap. The baby has grabbed onto Rick’s lab coat and was shoving it in his mouth, gently gnawing on the fabric, seemingly content. Rick smiles.
It’s late in the night, everyone but the two asleep. This is not so unusual for Rick, but is for Morty. The boy apparently didn’t want to sleep at all, struggling and crying when Rick had tried to put him down and instead of dealing with a crying baby that would wake everyone up, Rick decided to let Morty stay up with him, the two now watching TV together despite the fact Morty definitely had no idea what was going on on the screen. If he is being truthful, Rick is glad Morty didn’t want to sleep, it meant they could be alone together for hours.
Alone.
It’s dangerous, Rick knows, but danger has never stopped him before. Not like that is a good thing.
“Hey Morty,” Rick whispers. Morty doesnt look up, still preoccupied with the coat in his mouth. Rick tries again, this time lifting Morty’s head so he’s forced to look at Rick.
“Hey, Morty.” No response, of course, just Morty’s big eyes looking up at him. “You love grandpa, don’t cha?” Morty drops the lab coat from his mouth and smiles as if he understands Rick’s words. Rick takes this as a yes.
“Of course you do. I love you too, baby boy.” Rick leans in to kiss Morty’s forehead but stops for a moment before moving his lips lower and kissing Morty’s lips. It’s only for a few seconds but those seconds are pure bliss. Morty’s lips are so soft and delicious. If he died right in that moment, he would have died a happy man. As Rick pulls away from the kiss, he feels a slight tug on his hair. Morty had grabbed a few stray strands that he could reach and was now holding Rick in place. Well, not really, Rick could easily pull away but, instead, he keeps himself there and rationalises that Morty wants another kiss. He does just that, leaning in to kiss the boy again, pressing his lips harder and for longer. Under him, Morty squirms, a little uncomfortable and confused, but the squirming only helps Rick’s pants grow tight.
Rick pulls away, face red and panting heavily. Morty is staring up at him, lips flushed and plump from Rick’s own. In that moment, Rick can feel all his restraint falling away by the second, his lust, his need for Morty taking over his mind and heart. He can feel himself shaking, whether from fear or anticipation, he cannot tell. Slowly, Rick reaches out, trembling, hand grabbing at Morty’s shirt and lifting it, exposing the boy’s soft chest and tiny nipples to the hungry eyes of a gross old man.
“You’re so beautiful,” he whispers, voice trembling. Morty makes a gurgling noise then smiles again. Rick’s heart melts. He can’t hold back anymore, he just can’t.“I’m sorry,” he adds.
Rick picks Morty up and takes him to the garage, locking the doors and making sure his sound proof barrier is up. He didn’t want to be disturbed. Rick shakes off his lab coat and lays it on his workbench, then places Morty on it. The boy giggles and coos, unaware of just how much danger he is in. Quickly and with practiced ease, Rick takes off Morty’s shirt and diaper, leaving him naked and exposed. Rick’s heart is going crazy in his chest, he’s going to do it, he’s really going to molest his own grandson. Maybe if he were normal, that thought might have finally pulled him out of whatever horny stupor he was in, but he wasn’t normal and if anything, it just made his dick harder.
For a moment, Rick is overwhelmed with all the possibilities of where to start, then decides that he’ll work his way down from the top; kisses go from the top of Morty’s head all the way down to his chest. After the kisses, Morty’s nipples are next. Rick licks small circles around his small nipples then takes a soft bite of one, making the boy squeal loudly; Rick tells himself it was a squeal of pleasure. Continuing his path down, Rick licks over Morty’s tummy, coating the skin in a thin layer of saliva; he makes sure to pause at Morty’s belly button, dipping his tongue in to earn another squeal from the boy. Morty is absolutely delicious, his skin is so soft and delectable, so addictive. Rick isn’t sure he’d be able to stop himself from ever doing this again, he knows what his grandson tastes like and now never wants to stop tasting him.
Rick finally makes it down to Morty’s cock and immediately takes it, balls and all, in his mouth, alternating between sucking on the soft flesh and playing around with it with his tongue. Under him, Morty is now squirming around and making loud, distressed noises that Rick ignores in favour of sucking harder. He only stops when the tightness of his pants turns to pain. Pulling away, a string of saliva connects Rick’s mouth with Morty’s cock, broken by Rick licking his lips.
Rick hurriedly does away with his belt and unzips his fly, near ripping off his pants in his rush to free his cock’s constraints. Wearing no underwear meant that his cock bobbed free easily, flushed and heavily leaking precum. Looking at the size of Morty then the size of his own cock he realised that there was definitely no hope that any dick penetration was going to be happening any time soon. But his dick wasn’t the only thing he could penetrate with. Rick smiles as he rummages around to find one of his bottles of lube. Successful, he grabs the bottle, opens it and pours a large amount of lube over his pointer finger; he doubts he’d be able to get more than one into Morty’s little asshole.
Turning back, Rick sees that Morty has one foot in his mouth, as if showing off his tight ass to his grandpa. Rick licks his lips again and moves back towards Morty, all inhibitions and concerns over what he is doing long gone. He is a disgusting man and now he revels in it.
Spreading Morty’s cheeks with one hand, Rick admires the boys hole for a second, watching it, watching the way it seems to invite him in. Then he presses his finger against the pliant flesh but doesn’t push it. Morty yelps at the feeling of something cold and unfamiliar against his ass. Rick waits a minute then, slowly, pushes the tip of his finger in a couple of centimetres. The slow pace does nothing to stop the panic filling Morty, who begins to scream and cry, thrashing around to try and get rid of the intrusion.
This quickly frustrates Rick. He uses his non penetrating hand to hold down the baby, using just the right amount to keep Morty down without hurting him. Morty still struggles with all his baby might, but there isn’t much he can do against a much stronger and larger Rick. Seeing that the thrashing had stopped, Rick continues to push his finger in, going until he physically could not, Morty continuing to cry and scream all the while. The boy’s obvious pain did absolutely nothing to deter Rick. In fact, it made him even harder.
Not wanting to wait, Rick began pumping his finger in and out of Morty’s asshole, picking up speed with each renter until he was viciously raping his baby grandson with his finger, all the while fantasising that it was his cock instead pumping in and out instead. Rick watches as tears stream down Morty’s face, his eyes puffy and snot covering the bottom half of his face, and he can’t help but think that in this moment, Morty is the pinnacle of eroticism.
As Rick feels himself on the verge of cumming, he gets an idea. He pulls out his finger and grabs a hold of his cock. Bringing it up to Morty’s lubed up asshole, he presses just the tip against the entrance, careful to not accidentally penetrate the boy, and begins to furious pump his cock. It doesn’t take long, and soon Rick is cumming, his jizz spilling into Morty’s ass and filling the boy up so much that his belly even distends a little, making Rick moan at the sight. After making sure every last drop of cum has been pumped into Morty, Rick pulls back and watches as cum leaks out of his ass and onto Rick’s lab coat.
“Fuck, baby boy, you’re so hot,” he mumbles mostly to himself. Rick takes a step back and watches Morty for a moment. The boy is still crying but has long since stopped screaming, his little lungs having grown too tired. He wishes he could keep Morty like this forever, but he knows he would grow frustrated of not being able to actually penetrate the boy with his cock. So, he resigns himself to watching the boy grow and thinks that maybe, when the boy is 4 or 5, he age he estimates Morty would be able to take his dick, he might be able to stop the ageing and keep him like that forever. The thought is tempted but he knows better than to settle on an idea right after sex.
Instead, he decides he should clean Morty up and get him to bed. Before he does though, Rick grabs a camera from his piles of junk and takes more than a few photos of Morty splayed out on his lab coat, cum leaking from his ass and tear tracks down his face. Perfect jack off material. With enough photos taken, Rick actually gets to cleaning Morty up, wiping of the tears, snot, sweat and cum off then redressing him. As he finishes up, Morty lets out a yawn; perfect timing. Rick picks Morty up and the boy reaches out to him, seeming to have forgotten what had just happened to him. Rick smiles, kisses Morty’s lips then takes him upstairs and into his room. Morty goes down easily, too tired to fight, and falls asleep minutes after.
Rick watches him, content. Morty is so cute when he sleeps, peacefully unaware of the dangers of this world; of the dangers in his home.
