"I-I can't..."

"Please do, I - I'd love to hear it"

There was silence as tension gripped at Specs' throat, putting him into some sort of choke hold that stopped him from releasing anything more than a few "uh" and "um" sounds, stumbling over his words and clearly unable to "explain" himself, as he'd mentioned. Rick - noting this - began his interrogation, flipping through each of the papers to show off his "evidence."

"Well, if you're not going to tell me anything, we'll just have to take a look ourselves. In this one it looks like you're bending over for me and pleading for 'granddaddy' to 'be more gentle, it - it hurts?' Looks like I'm - urp - I'm r - real deep in that ass, huh?"

Rick slid that picture off of the desk and let it hit the floor, showing off the next picture underneath it, a scowl of disgust on his face as saliva dribbled off of the edge of his lips. Specs looked down in shame at Rick's reaction, not knowing what to do or say next. All he knew was that he wanted to get out of here. But that didn't stop Rick from lashing the hell out of Specs for all of the crap that he'd drawn.

"O - O - Or how about this one where you appear to be jerking me off and asking me if it feels good? Wh-What do you take me for? The look on my face certainly shows pleasure. Oh, this one's interesting, this one has us fucking on my god damned desk. L - Look at this shit, you knock - knocked over all my shit. I - It's a fucking mess on the floor."

"I - I can explain..."

Morty was particularly proud of that one, so he'd cringed as he'd heard Rick's critique of that one. He was still at a loss for words and Professor Rick could clearly see that. Sighing with exasperation, he'd grabbed Morty by the chin and pulled his face up, eyes trained on Morty's in an intense glare, his monobrow furrowed with a ferocity of an educator seeking to return his student to the straight and narrow.

"So, what's with these drawings, Glasses Morty?"

"I - I just… just..."

"And don't you dare lie to me."

With the way Professor was holding him, Specs couldn't help but think about all of the things they could be doing. As a result, the inevitable boner formed in his pants, knowing he'd have gotten like this if they were just alone in the same room anyways. This brought back memories of his original Rick before the "Evil Rick" incident… He was able to look into Professor's eyes and see those same eyes that had been torn from him so long ago. In his dimension, everyone wore glasses, and his Rick wore them with thick lenses, making it difficult for Morty to ever see his eyes directly. Now that he could, he found himself hypnotized. Biting his lip and taking a breath, Morty returned Rick's gaze with one of his own, his own shyness extremely apparent.

"I - I - I was… I asked Photographer Morty to get pictures of you, s - s - so that I could… Draw you… and me… a - a - and m - m…"

Morty trailed off, seeming to anger Rick and he'd moved his hand down to Specs' neck, thumb and index pinching his trachea ever so slightly apply pressure in just the right spots to stimulate Morty's pressure points, causing the younger boy to cringe and spit out his answer in a panic.

"M - M - MASTURBATE TO THEM! I - I WAS MASTURBATING TO THEM! ...I - I think you're really hot Professor..."

"Oh, really? You s - sick fuck. I may - may not be your Rick, but I'm still genetically c - connected to you. I - I'm your god damn grandpa. How often do you - urp - you stroke it to me?"

Morty was caught off guard by that question, not really knowing what to say. He hadn't even thought about it before, considering he did it so constantly. He'd never actually kept count. That'd be weird. Even so, as he'd processed the question in his head, he found himself thinking about just how often he'd did it. Clearing his throat and feeling the slightly additional pressure of Rick's fingers on his neck as it moved, Specs was slowly pushing the answer out past his lips.

"Um… I, uh… I - I don't know… wh - whenever I think about you… and I don't think anyone's paying attention to me. I've even done it here… in this class… when everyone was busy testing and you weren't paying us any attention… I - I mean, it's not like y-"

"Noticed? O - Of course I did. Do you take me for some kind of schmuck?"

Specs' heart sank as he'd realized he wasn't nearly as sneaky about it as he'd thought. This only served to make him blush even harder and try to turn his face away. Of course, Rick didn't let go of him, the older man keeping his eyes on Specs'. His struggles in vain, Morty resigned himself and rest his head in Rick's hand, tears forming at the edges of his eyes and he'd began sniffling.

"You're crying now? Jesus - Look, I'm… I'm not mad. It's kind of cute, your little crush on me, I mean.."

"Wh… What?"

"It's clear that these pictures are what you think about when you masturbate to me, Glasses. So, tell me. If we were to indulge, which one of these pictures would you want to play out?"

The smirk on Rick's lips was unmistakable for anything else, the glimmer in his yellow teeth almost alarming for Morty, not expecting this development. Everything he'd done to hide his shame and now he was in the situation he'd always dreamed of? What kind of weird fantasy world was he living in? Just at the very thought, Morty began to shiver with anticipation, not knowing what Rick was thinking, but having a feeling that things would start looking much better from this point on. His unaddressed erection began to dribble with lust and excitement as he was now at a point where he wasn't sure what was going to happen next, but that was where all the fun laid.

"Aw, jeez, Rick, I - I mean, I c - can't…I - I guess I'd be happy with anything, I'm sure anything you do to me...I'd like."

"Guess I'll have to pick, since you clearly can't even process this. Typical Morty."

Before Morty could respond, Rick moved his robe to the side, revealing his already hardening cock. Rick dragged the teen's head down to his waist, grinning now and slapping the tip of his dick against Morty's cheek, rubbing into it ever so lightly to entice the boy. Just the aroma was enough to get Morty dizzy with delight, breathing in and sighing contently as he'd looked up at Professor from below.

"What do you want to do with it, Glasses?"

"O - Oh please, Professor, c - can I suck it…? I - I wanna taste you… Y - you're sooooo big… It looks delicious..."

"Fuck, a full year of teaching you abandoned Mortys and you're the first to offer a hole to me so willingly. Like, Jesus, so many of you are so s - sick, wanting to get stuffed by your own grandfather...figures my grandson would be such a fucking whore. D - Did you suck your original Rick's dick too?"

"N - No… never… I -"

Morty was cut off by the feeling of a thick rod in his mouth, jamming his jaw open and filling him up. His eyes began to roll up in pleasure, moaning delightedly as the tip of Rick's shaft struck the back of his throat, causing him to gag a bit and he'd been forced to take a deep breath through his nose to try and not suffocate. Rick groaned with the pleasure as he'd felt the hot feeling of a Morty's supple mouth wrapped around his junk. The other Ricks weren't kidding when they'd mentioned to him that he could take advantage of his position. Of course, he just wanted to teach these Mortys to be good Mortys to whichever Rick they ended up with. Naturally, if some of them were a little more sexually oriented - Professor had no complaints. If these Mortys needed "quality control," then he would be glad to provide. With a 90% retention rate, Mortys were more willing to stay with their Ricks and he was proud of his work.

"How's it taste, Glasses? I'd ask you to answer, but it seems like you're a bit stuffed at the moment."

There was a bit of a gurgling noise from Morty as Rick picked up one of the pictures on the desk and looked at it, enjoying the view of Morty riding his dick while stroking his own. Every detail was well defined, each drop of cum spread out on Morty's stomach and shooting from his own dick was such a sight to behold. Right down to the veiny design on Rick's rod, the drawing was certainly something worth stroking it off to. Seems like Glasses was quite the talented artist. Rick was pulled from his thoughts when he'd realized that Morty was almost passed out from pleasure, eyes rolling. Pulling the boy's head off of his dick, Rick let Morty lean back against the chair, coughing up threads of saliva and taking deep breaths through his throat. The look on Rick's face was smug with power and pleasure as he'd pulled Morty up and dragged him over to his desk. Inevitably, he'd tossed the boy onto the wood - knocking over all of his shit - and began undoing Morty's pants, the teenager in a daze, but very visibly excited. At least, the goods that Glasses was sporting was the same size as any other Morty's. That's what Rick liked. Consistency. He'd gripped the dick in his hand and began to roughly work it, Morty's hips jerking in response to the new stimulation and the boy moaning with extreme pleasure.

What happened next is what caught the boy off guard was when he'd felt something get jammed into his asshole, squealing with surprise as Rick had pushed his index and his middle fingers into Morty's asshole, the two digits squirming and stroking against Morty's sensitive walls, making the boy moan more and more like a dog in heat. There was a brief moment when Rick's fingers stopped, though, and he'd began to open up the space between his fingers, spreading Morty's anus out a bit and making the boy gasp with surprise, air trapped in his throat as the best he could manage was a "Aauuuu…! Aw-ooooh…!" His fingers continued to open and close, stimulating Morty even further. With what Rick was planning, though, this was just the tip of the iceberg. Or rather, the dick.

Between the stroking of his eager member and the stimulation of his asshole, Morty had lost all focus on the world. His glasses were tilted ever so slightly and his hair frayed, hands grabbing at the edges of the desk as he'd tried his hardest to maintain himself so that he could enjoy this to the very end. He found himself unconsciously whining when Rick had pulled his fingers out of his tight hole and was treated the the explosion of a sensation when Rick had bottomed out in his asshole, screaming in pain-pleasure as his anus was spread out even more than Rick's fingers prepared him for.

"Th - this what you want, you piece of shit? F - Fuck, you feel so good! Your fucking anus could rip my god damned dick off if I weren't so fucking thick. I could feel that tight ass ring. People would k - kill for this prime cut of meat."

"G - Gee, th - thanks, Professor…"

"N - No. Call me Grandpa, baby. L - Like a good Morty would. Like I've taught you allllll semester."

That statement followed with Rick pulling his length out to the edge of his shaft before bottoming out inside of Specs again, his glasses even more off-center now as he'd moaned and pushed back with his hips to try and take Rick as deeply as possible.

"O - Oh, G - Grandpa Rick! Grandpa Rick, f - f - fuck me!"

"Don't gotta tell me twice! Grandpa's gonna take real-real good care of you."

It wasn't long before Rick was pumping in and out of Morty, pinning him to the desk and pushing his dick down to the base with every thrust, working Morty's insides with vigor and eagerness betraying his age. Morty was a moaning, groaning mess of lust and pleasure, practically drowning in it as he'd let his head fall back and he'd allowed himself to just be a cock sleeve for Rick.

"Ah-ah, you're such a good little slut for me M-Morty. You're grandpa's good little boy. Got-got such a fuckable hole. So fucking tight."

"Hhoooohh, Grandpa R-Rick…."

After several long moments of Rick pistoning into Morty, he'd grit his teeth and pushed as deeply into Morty as he could, not even giving a warning as he roared and shot a stream of hot sperm into Morty's ass, filling him up with jet after jet of steaming jizz before pulling out and continuing to erupt all of his body, shooting a strong release of white over his face and smothering his glasses. His breathing was heavy as he'd looked down at Specs, who by this point had been fucked senseless and had passed out. Appreciating his work, Rick grinned and spat on Specs, using Spec's pants to clean off his dick before tossing them on top of the boy and walking away. Another Morty, another day.
