There have been many requests for watersports on and off Ao3, so here it is!
It's pretty tame, so if you're not into it, you should be scared off too much. :)

Enjoy, and happy sinning!

There was a certain grogginess looming over Rick's head, groaning as he'd felt the full force of his hangover, the previous night being particularly harsh to his alcoholism. Rolling out of bed and allowing himself to faceplant onto the carpet below, he'd slowly crawled over to his desk and pulled out a tube of medicine, twisting the top off before popping a few capsules into his mouth and downing them both with a hearty gulp from the fluids in his flask. The moisture on his tongue and lips would be more refreshing if it hadn't all dissipated so quickly and he was forced to pull out a bottle of water from his desk as well, downing the whole thing as a desperate attempt to rehydrate himself. Once he'd chugged the entirety of the bottle, he'd groaned and took a deep breath. The sudden ingestion of liquids caused a familiar feeling to stir in his groin and he'd groaned more now - this time in annoyance. Human processes were cumbersome, but he'd lived his entire life going through the motions. The man slowly got onto his feet and trudged out the door, pulling it closed behind him before he'd made his way to the bathroom.

Burping loudly, he'd pushed the door open and his bare feet dragged from the carpet onto the cold, lifeless tile, sending a shiver up his body in response to the change in temperature and texture. Instincts kicked in more clearly now as he'd stopped in front of the toilet and lifted up the lid and seat, unzipping and unbuttoning his trousers before he'd let his dick flop outside of its cloth prison. Guiding his flaccid genitalia in the direction of the porcelain in front of him, he'd allowed his muscles to relax now and a stream of gold released from his body, a sigh of relief and release leaving his lungs. His head fell back as he allowed himself to wallow in the self-satisfaction of doing the proper, human thing and pissing into a toilet. After just a moment, though, Rick's eyes wandered down at the steady stream of liquid waste, watching the stream splash against the water inside of the toilet and being strangely enamoured by it. This didn't last long, though, and in just a few more seconds Rick was done with his fascination with piss and was moving on with his life.

Zipping his pants up again, Rick turned towards the sink and washed his hands, noticing the distinct lack of breakfast-smell in the air. Maybe Beth hadn't made breakfast today, so it was time to eat some cereal. It had been a long time since he'd had a decent bowl of Strawberry Smiggles anyways. He'd made his way downstairs now and poured himself a bowl of the fruity crisps and brought the bowl to his nostrils and gave that a hearty whiff.

"Oh Mr. Tophat Jones, I would munch on your intestines for these too."

And as he'd moved over to the fridge, he'd pulled it open and discovered a distinct lack of milk. Which was odd, because Beth had just done the grocery shopping two days ago. There was no way that they'd run out of milk within that amount of time. His eyes thinned suspiciously as he'd closed the fridge door and carried his bowl over to the dining room, wondering if anyone was simply holding onto it. His eyes did indeed see the milk jug. Inside of it, though, was not milk. And next to the jug? A particularly nervous Morty, with an empty bowl next to him. Very blatantly annoyed, Rick had put the bowl down onto the table and rubbed his temples.

"What the hell Morty, ever thought maybe - URRRP - someone else would have wanted that milk? Instead you do whatever the fuck with it and replace it with water? How am I gonna eat this cereal? Dry like a f-fucking simpleton? Or do you expect me to eat cereal with water like some sort of idiot?"

"S-sorry, it's just...ugh...I was reading online about how it's good to drink lots of water...

and y-you know, why not just bring a whole jug of it around with me? I saw a few guys around town do it because of the summer heat, so why not, r-right?"

Rick was already suspicious of Morty as-is. All of the sneaking around, finding out about his little side gig, and now this? It seemed Morty was practically saying to Rick, "I'M A MORTY, LOOK AT MEEEE." The old man's eyes thinned to a fierce glare as he'd turned back to the kitchen to pour his Strawberry Smiggles back into the box. As he'd done this, Beth stepped into the kitchen, a bit dishevelled and seemingly recovering from her own hangover. She was able to take note of Rick's little problem, though.

"Did the kids drink all of the milk or something, Dad?"

"Yeah, that's what it looks like."

"Oh, don't worry about it. I'll just make you something to eat. I… overslept a little today. So sit back and I'll have some eggs and bacon for you in just a bit."

"Th-Thanks, sweetheart. You're the best."

Rick hugs his daughter a bit with one arm and kisses her forehead, Beth mouthing "Oh, Dad" before smiling and turning to cook her father some dinner. Rick's attention was soon returned to the dining room, Morty just about done with his own breakfast and seemingly looking through some other things on his phone. Which Rick now noticed was a new phone. When the hell did he get that? He'd taken a seat at the other end of the table, eying Morty and connecting that Morty had a bunch of money to do whatever he'd liked at this point. Noticing this, Morty raised an eyebrow at Rick and slowly scooted out, uncomfortable with the way he was being scrutinized.

"Wh-What's up, Rick?"

"Oh, n-nothing. Just a little more than a bit annoyed at not getting my Strawberry Smiggles, Morty."

"I already apologized, Rick. Geez... Wh-What the hell's got you all w-w-worked up today?"

"I told you, it's nothing. J-Just thinking about our next b-big adventure."

Morty looked a little guilty as Rick had mentioned that, the old man noting that reaction and connecting that to the fact that he was more than likely doing cam shows instead of hanging out with Rick. He'd turned away, scoffing at the young adult across from him and continuing to wait for Beth to provide his nourishment. Fortunately for him, that hadn't taken too long and Beth had come into the room with the promised bacon and eggs, leaving the plate in front of her father and supplying him with a fork. Rick had nodded his thanks to her before turning back to where Morty… was previously sitting. It seemed the boy had taken the time to go ahead and leave - not even so much as a "see you later" or "I'll catch you on the flip side" or whatever the fuck kids say these days.

Not that it mattered. Rick already knew what the boy was going to be doing later tonight anyways. At this point it was time to capitalize even more on that premium account. The only curious thing at this point was that god damned gallon of water Morty was holding so close to his heart. There was something nagging Rick at the back of his mind, not quite sure what to think of it all and the answer not quite forming in his brain yet. Maybe that answer would come tonight as well…

Distracting himself by fixing and tinkering with various machines in the garage, Rick had forced himself to remember when Morty was streaming and made note of the fact that no one else was home besides the two of them. Man, it seemed that the little bastard was better at planning things out than Rick had thought. Summer was out with her college friends and Beth had a late night ahead of her, providing surgical assistance to horses in their times of need. Typically, Rick would leave Morty alone at around this time - knowing full well that the kid needed sleep. Using that information, Rick knew Morty scheduled this show with all of that in mind. Seems like Morty had grown craftier in all of the years that they'd been adventuring together. Returning to his room, Rick turned on his PC and let the screen whir to life, quickly logging into the machine and onto his account on Masturbation With Friends. GrandsonFk3R. While it wasn't as inconspicuous as Rick would normally like, it was to the point and he wasn't going to go through the trouble of another string of names that were already taken.

As the stream flickered to a complete connection, Rick had made the connection that Morty was in the bathroom, sitting in an empty bathtub. What was interesting was that he was already naked and stroking his blood-filled phallus, licking his lips and looking into his camera with a sultry stare. Rick gulped a bit as he could feel his loins stirring once again, his fuck muscle twitching to a firm stature as well. The older man was already removing his belt and pushing his pants down to his ankles, allowing his shaft to wave around freely before he'd clenched it in his left hand, beginning to slowly tug at it to get the juices flowing.

Morty, on the other hand, seemed to be giggling and watching as messages flooded the chat room. All of them seemed to be familiar with Morty and they all sent messages of their desire to fill his tight anus with their allegedly large cocks. Grimacing a bit at the thought of other men taking his grandson, Rick had pushed the chat to the side bar, noticing that messages were still pouring in and his eyes would wander off to the side every so often to catch note of a few that caught his interest.

22:03:40 DADDYSSLUT35 - Yea look into the camera babe

22:03:47 Kum4meplZ - dam u so hot morty

22:03:55 BeatmeatM3 - stroke it nice and slwo

22:04:00 Grandadsbitch1959 - Use that tongue on my dick sexxi boi

In a move that caught everyone off guard, Morty turned his body around and allowed his ass to face the camera, bent over on his knees and his face pressed against the bottom of the tub. He was still stroking his dick, though, and he used his free hand to spread his asscheeks out a bit, revealing his puckering, pink anus - an almost inviting motion as he'd undulated his hips ever so slightly to allure all of his viewers. His hand let go of his cheek before long though, lifting to give it a hard spank, leaving a pink handprint where he'd struck himself. Accompanying the snap of his palm landing on his flesh was a moan of pleasure, the hand on his shaft gripping a bit tightly in response to the pain. Rick could feel some precum form on the tip of his dick as his excitement skyrocketed, but he'd kept himself under control. He'd had an entire livestream to get through.

22:12:23 BeatmeatM3 - Ahhh shit look at that thight little asshole

22:12:27 SAUsageHUT - God damn son wanna put my hug3 cock in that teen ass

22:12:48 GAYGrampa599 - YEAH SPnk That Azzzz sum more or im gona have to du it bitch

"Alright, daddies, it's almost time to finish up here~ And we're going for the golden goal tonight, since we h-hit that point last time."

He'd given himself one more teasing spank before flipping around, Morty was back to facing the camera and he'd licked his small, soft lips in anticipation of the supposed "golden goal." Morty spoke into the camera in a different manner than Rick was used to, though. Those clips that he'd sampled on yesterday were only a shadow in comparison to hearing his voice live. Saying all of these sensual things was enough to push most men who were into this sort of thing to orgasm. Of course, Rick wasn't used to hearing Morty's voice like this, so he was especially hard. There was something about Morty's eyes in the camera that set off Rick, almost as if Morty's look was actually for him. Of course, that was the nature of cam sites like this. It was to cater to every watcher's needs and desires. As Rick made note of all of these things in his mind, though, he'd spied something familiar in view of the camera. A milk jug. That was now completely empty. That thought was interrupted by Morty's voice going up in pitch, Rick noticing that his stroking of his dick was getting particularly swift. Soon, Rick was matching Morty's pace, groaning and listening to Morty in tune with himself.

"Y-You l-li-little shit, f-fucking showing off to all th-these fucking perverts - f-fuck - just f-fucking show me what you got!"

Morty came first, spurting all over himself as the cum shot upwards and coated his upper body, globs sticking onto his chest and dripping down to his abdomen, covering one of his nipples as he'd moaned delightedly. This pushed Rick to the edge and just as he was about to explode Morty's livestream lit up with activity, Morty's spent-but-still-hard dick now shooting a stream of piss into the air as an arc, landing on his chest and washing the spermy coating onto the tub below. The stream lasted a good fifteen seconds, washing off the impurity of his jizz with the impurity of that golden shower - an apt name in a situation where he's sitting in a tub. The sight of Morty's body glistening with gold was all it took and Rick came harder than he ever thought someone his age could, spraying his screen with a grimy layer of cum and even spurting out of control onto his keyboard and speakers. He'd collapsed against his chair - completely spent and remembering just how many times he'd cum yesterday. Clearly today's stream hit his kinks just right.

22:28:51 Gotdatgudseamen - HOLYSHIT

22:28:59 Scholongferdayz - So sexy and wet!

22:29:05 Babeegotbakk - YESSSSSS! # ! THIS LIttle FREAK !

22:29:12 Dinga0000ling - This bitch knos how to maek me cum wowwww….

"Alright, my h-hot and horny daddies, thanks for watching the show. Remember, t-tomorrow is this month's deadline for the big one-on-one so that a special someone can show me how much you love this t-tight hole of mine~ I'll see how many of you have put in for me and whoever shows me the most bling will get the fling~ See you tomorrow, daddies!"

Hearing that, Rick's body sprang to life, looking all through Morty's profile and record donations and figuring out how much he'd need to give to be that one. Luckily, none of these "daddies" were putting in even as much as Rick could put in. Time to show Morty the real value of a shmeckle.
