AN: This story is based on the idea from cheeky-cheek-kiss. My muse was instantly hooked on this. I hope that this matches what you had in mind and you like it -^_^-
This is just a small start for now, but I decided to write this as a short multi-chaptered fic, so you already get something to read without having to wait for too long. Also, I'm still undecided if I should end the story with some smut or not…

Warnings: Rick/Morty, fluff and angst, mutual pining, slow burn, also some gore

Unerasable Love – Chapter 1: The First Time was an Accident

If Morty was being honest with himself, he had probably always felt something for his Rick. More than just the admiration that he had for the genius. Feelings that went beyond the familial love that a grandson would hold for his grandfather.

For one, there was the trust.
Even if it might not be the wisest decision, he trusted Rick. Trusted him with his life.

For all the trouble, risks of death and occasional humiliation that Rick caused him, he knew that he was always safe with his grandpa. No matter how out of control their adventures would get, Rick would fix it. Even when he would get hurt, Rick would heal him afterwards – fix him back up as if never anything had happened to Morty in the first place.
At times, Morty even wondered why he used to freak out so much during their raids because he always came out completely fine afterwards.

Yes, he trusted Rick and knew that the scientist would never let him die or would allow anything too bad to happen to him.

It wasn't only this deep trust, which made him feel so strongly for to the other though.
There was also a certain attraction for his amazing grandfather…

However, Morty had never allowed himself to dwell on those thoughts for long and usually ignored those feelings. He knew that it wasn't normal.

Normal was having a crush on Jessica or being interested in other pretty girls. Finding his grandpa sexually attractive was anything but normal. It was just plain weird.
And if Rick would ever know about it, he would either use it against him and humiliate Morty or be really grossed out by his grandson. Morty liked neither of those options, so he simply pretended that he was "normal".

Most of the time, it was easy to ignore those feelings because Rick was enough of an asshole most of the time and Morty could always find one thing or another happening on their adventures that made him angry at the scientist.
However, there were other times when it wouldn't be so easy and today was just one of those days.

Surprisingly this day had even started out pretty nice.
Instead of the usual crazy and life-threatening adventure, Rick had actually taken him to a huge fair in the Firibula System. Rick treated him to all sorts of alien snacks that were similar to cotton candy, ice cream and other delicious-tasting things. They wanted to go and watch some sort of circus show in the big tent that stood in the center of the fair, but Rick needed to use the restroom first.

"I'm gonna go and take a dump. You wait here, Morty." He had said and then left.

Morty just nodded and stood to the side, between two stalls, so he wouldn't be in anyone's way while he waited for his grandpa to finish.

This was actually nice and he wished that Rick would do this more often with him. He blushed a little as he thought that this felt like a date, but quickly shook his head to get rid of that ridiculous thought again. Rick was just acting like a real grandpa for once and seeing how rare those occasions were, he shouldn't sully the moment with his abnormal and confused feelings.

What happened next was completely unexpected and hit the boy out of the blue – quite literally.
More precisely, it was a hard object that hit him in the back of the head and cleanly knocked him out.

The brunet drifted in and out of consciousness as he was dragged over the ground, his vision blurry.

Vaguely he could hear a voice that said, "He's able to see where we're going like this so put a bag over his head."

After that, everything turned black and it became harder to breath.

By the time, that he finally came around again, he found himself in a dark room and tied to a chair. A desk lamp suddenly turned on and its shine was directed at his face, forcing him to squint and also increasing the pounding inside his head.

"Where's Rick Sanchez?!" A scratchy voice demanded loudly, making Morty groan in pain. "We've seen you with him at that fair so don't try to deny that you know him! Where is he?!"

"I-I don't know where he is." The boy replied.

It wasn't a lie. Who knew how much time had passed since these guys had kidnapped him? By now, Rick was most likely finished doing his busy and could be wherever. Hopefully, he was looking for Morty now.
However, his grandfather probably didn't even know that he had been abducted by these guys. Morty still believed that Rick would come to save him though!

"Are you sure you wanna stick to that answer?" The guy with the raspy voice asked and some bigger alien who stood next to the figure was audibly cracking with his knuckles.

"I really don't know where he is right now. Probably still at the fair." Morty began to sweat at the obvious promise of pain, but he was sure that lying would only buy him so much time and maybe they wouldn't even believe him.

"We'll see about that." The small alien said and then gave his gorilla-like partner a signal.

Morty tried to shrink in on himself as much as he could, but tied up as he was, he was practically immobile right now. Without a way to dodge or defend himself a hard fist connected with his face.

"There's more where that came from. Are you sure that you don't know where Rick Sanchez is?" his tormentor asked.

Since the large alien was shielding him from the light, he could see that it had blue skin, a single big green eye and two small antenna…or maybe those were horns.

"I don't know!" Morty yelled in defiance despite his aching cheek, which rapidly began to swell and bruise.

The fist connected with his face again, this time smashing against his other cheekbone.

The smaller alien, who seemed to be the boss, spoke up again. "Then I'll guess, Bliploo will have to convince you until you change your mind."

"I really don't know where he is!" The air was knocked out of Morty as the next punch landed in his stomach and he could only wheeze, "You're going to regret this. Rick is going to come for you."

"Oh, I actually do hope that he will come to rescue his little boyfriend." Boss alien sounded delighted.

The brunet blushed and had a weird feeling in his stomach from the false assumption that had nothing to do with the beating that he received.

"I'm not his—" he didn't get any further as the punishing fist hit him hard enough to break a rib.

The boss alien continued. "When Sanchez gets here, he'll be as good as dead."

It worried Morty a little to know that his kidnappers where trying to lure Rick into a trap with him as bait, but he also knew that his grandpa was smart and foresighted enough that he would surely be aware of this and manage to trick the bad guys.
The only thing that he should worry about right now was his own health as the only thing that he could do now was hold out until Rick would come.

Unfortunately, the scientist seemed to take his sweet time with the rescue mission. The beating went on for hours and at one point the pain became so much that Morty had started to cry and wail like a little kid. Everything hurt so much and he was so close to tipping into unconsciousness again.

'Where are you, Rick? What's taking you so long? You are coming to save me, aren't you?' he wondered.

He didn't want to think that Rick had just abandoned him. Of course, he knew that his grandfather still had that voucher, but he had to believe that Rick hadn't just decided that coming to save him was too much of a hassle and went to get himself a new Morty instead.

He sobbed pathetically as he felt his last shred of hope quickly slip with each passing second that he was in pain.
Even the buffoon that was beating the living shit out of him was breathless and becoming tired and his boss was constantly on his walky-talky to check with his henchmen if Rick Sanchez had already showed up.

Morty's ears perked up though as he heard the boss ask for one alien and didn't get a response.

"Shloomie, are you there? Over." His voice became panicky as only static answered him. "Please answer me, Shloomie! Over."

A weak smile stole itself on Morty's face. He knew what this meant. He was finally here.

The leader alien tried to contact his other underlings, but from each line, only static-y silence greeted him. Realizing that his men were strategically taken out one after another, made the small, orange-skinned alien with the three eyes almost hyperventilate.
Even the blue cyclops had stopped hitting Morty and looked with a questioning and slightly scared stare at his boss, clearly awaiting a good plan and further orders on what he should do now.

Before the boss could even utter a word, a metallic tentacle-like appendage with a claw on its end broke through the wall and snatched the gorilla, pulling him out of the room as quickly as it had entered.
The orange alien screamed, obviously freaked out by the situation.

Next thing, the entire wall crumbled into tiny pieces and as soon as the dust settled again, none other than Rick Sanchez stood there. On the floor around him was a mass of presumably dead aliens. He wore something like a backpack that had two thick metallic arms sticking out of its sides.
Also, he looked super pissed off right now.

Morty's heart made a little jump at his grandfather's heroic entrance while his kidnapper looked rightfully terrified.

Rick's expression darkened when his eyes fell on his grandson.

"Bad move, Greemo." He said sinisterly. "No one fucks with Rick Sanchez or what belongs to him."

Before Greemo could do anything, the two metallic claws grabbed him tightly and squeezed literally the air out of him. He struggled and plead for his life, but Rick had no mercy with the scumbag.
The force of the gadget kept bearing down unrelentingly and the alien's face drastically started to change color.

Morty had to look away as Greemo's three eyes plopped out of his skull with sickening pops. Only few seconds later, the rest of his body burst from the pressure and a green-translucent liquid that was probably his blood splattered all over the room, including Rick and Morty.

"Morty? Are you okay?"

Only after hearing his grandfather's voice directly in front of himself, did the boy dare to open his eyes. He was met with Rick's gaze, which showed genuine concern and worry.
Morty thought that this must have been the very first time that he ever saw the scientist look at him like that. Normally there wasn't much emotion in those blue orbs, but right now there was so much that it was almost overwhelming, taking his breath away.

"Let's go back home." Rick broke their eye contact to free the brunet from his binds.

Then he shot a portal and lifted Morty into his arms bridal style, judging that the boy was in no condition to walk by himself right now.

Even though Morty knew that his grandfather was extraordinarily strong and not only for his age, – something that he had always admired about the man – he still could only look up at the older in amazement. Feeling how Rick carried him with such ease, his muscles unwavering as if Morty weighed nothing, made the boy feel so save and secure as never before in his life and he wished that his grandpa would never let go of him again.

His eyes were dreamy and there was a light blush dusting his cheeks as he stared up at Rick, for the first time able to admire him from this perspective and taking in every hard line on the old man's face as he still frowned at their surroundings. A look that was so different from the one that he had mere moments ago when his eyes had been on Morty.
It only showed that he was still super pissed off from what Morty's kidnappers had done to the small brunet.

Still, Morty liked what he saw. Not even the green goo was able to take an ounce of his grandpa's handsomeness away.

Rick carried him without a word through the portal, which led straight into his garage and then sat him gently down on his workbench.

"R-Rick? I have to-to tell you something…" Morty's mouth began to move on its own.

He didn't know if it was the adrenaline rush or an effect from his head trauma, but he couldn't stop himself from talking. The feelings that he hadn't fully acknowledged until now and buried under the pretense of being a normal teenager with normal love interests in attractive females were fighting their way outside of him.

Rick only hummed in response as he rummaged through one of his drawers and retrieved something that looked like a gun. However, it was some kind of injector since there was a needle attached to it and the scientist casually screwed a vile with a green-colored liquid on it.

"Rick, I-I-I…" Morty continued to stammer while Rick injected him with the serum and after the initial painful prick, he could feel relieve flooding his body that took all the pain away with it. "…I really like you, Rick. I mean li-like really, really like you. What I mean is, I-I-I love you, Rick, and…not in the way that family does…"

The boy became quieter as he saw how Rick's face hardened with each spoken word and inside his chest, he could feel his little heart slowly crumbling.
This was a mistake! Or, more like an accident, really! He hadn't meant to tell him that! Why had he just said that? Why couldn't he just have kept this to himself?! Now Rick was going to hate him!

The scientist shook his head and sighed. "What the heck, Morty? You can't really mean that. How hard did these idiots hit your head for you to sprout such nonsense?"

"No! I really mean it! I lo—" Morty stopped himself and his eyes widened as he saw his grandfather suddenly pull a gun out of his lab coat and pointing it at him. "R-Rick?"

A tint of fear crept into his voice and into his heart. Even if he still trusted his grandpa with his life, the situation was worrying him.
Before he had the chance to ask any more questions, Rick pulled the trigger of his memory gun and took away the entire day from Morty's mind.

The elder pocketed his device again and sighed once more while smiling sadly at the brunet who was in a momentary haze from the sudden memory-loss. It would take him a minute before he would become fully aware again.

"Trust me, Morty. You don't want that. Not with me. I'm no good for you, Morty. I'd only end up hurting you. Destroying you." He said quietly and stroked softly over the still dazed boy's cheek. "It's better this way. For both of us…"

AN: I admit that this was heavily inspired by the Rick and Morty comic when Morty had been kidnapped, but on the other hand, I imagine that this is probably happening quite often.
