Sheldon had picked a particularly lousy time in one of his heats to be off of his game. That was for sure. He couldn't find a way to properly describe it, but when his vintage collector of a lover was helping him through rut, he gave off the vibe of someone with a limp dick. He was very much skilled at blowing his back out as much as he was with hunting, collecting items, and even at Jumpstyle, he'll admit that freely. But for him to sudden lack in performance when it was required, it sort of...disappointed him, to say the least.

It had been a week ago when he went into heat, which was demonstrated by him furiously humping a pillow with only his jockstrap still on, his wild hair glowing and flowing wherever it may, and his desire to mate or be mated off the charts. Sheldon walked in on him like this and proceeded accordingly. Restraining the overexcited Noxian without getting his clothes ripped off, which inevitably got reduced to tatters anyway, try to calm him down and use soothing words, and at least hope he sits still long enough for him to fully shed what remaining clothing he had that hasn't been shredded in the tussle before he got down to business.

When bent over and penetrated, the energy behind the Half-Noxian's thrusts started off great. His girth pumping in and out of his naturally lubed rectum as deep as he wanted him to and as fast as he'd go inside him any other time, leaving the twink in utter euphoria, given that he was in rut. This was his second one, thankfully, so the next one would be the last for this month. However, the swift, deep pace set by Sheldon has aptly decreased over time, as he could tell by how less often his prostate was pressed into, and how he had barely felt him go balls-deep. 

He could tell the older behind him was losing his edge in the intercourse, even while feral, considering he still had control over himself this way from previous experiences. He was disappointed, to say the least, and all he got in return was a breathless apology. Arthur hardly cared for that and proceeded to ride him the rest of the way, only saving the chiding for when everything has cooled down. And by then, Sheldon had given him the real reason behind his drop in performance, which was that he was tired, having worked the store by his lonesome and a recent intern and worked out for most of the afternoon before returning home.

He forgave him, of course. But his lack of performance repeated itself more than once, with different excuses. He was faithful to him and wouldn't dare think to cheat on him for any reason, but the reasons for his inadequacy were different and increasingly less believable each time, but Arthur held his tongue, he couldn't expect a good fuck every time, but it was preferable when he was in the mood - and in heat. He was quiet and understanding but was frustrated on the inside, and opted to let that be known today now that he's had enough of it. 

And he has a unique way of expressing it, what with Ryuken's concubine from the underworld being available for all males in need besides just his close companions. That concubine of Ryuken's was none other than the Anubis ruler, King Nacho. A womanizer for both men and women alike, as well as a shoulder to cry on. He leaned against the wall beside the open door in Arthur's bedroom, nude with his arms crossed and his penis fully erect as he watched the pinkette thrust up into the mouth of Sheldon, who was bent over on the bed over him with his pants pulled down to his knees and his bare tush tooting up for the blue dog's viewing pleasure.

"Ahh, as I've said before, Shelly, you have been excessively lacking in your duties of pleasing me, and I do believe that will be ending now, starting with a demonstration by a special guest," Arthur explains, casually fucking his boyfriend's mouth as he sits up to grab a small bottle of lube laying within arm's reach, popping it open with a thumb as the guest approached the couple behind the older man, taking his meat and slapping it on both asscheeks - left and right. "You won't have to pull off to see for yourself, he's Ryuken's side mate. And I do hope there are no hard feelings afterward, right, Your Omnipotence?"

"Yes, of course," Came the deep, accented reply as he prodded the hybrid's hole. "And don't worry my friend, I'll be gentle with you. If your lover allows for it."

"Too right," Arthur nodded, with Sheldon on his dick whimpering in response to feeling a bulbous tip press against him. He hears something squirt and felt a familiar wetness drip onto his hole, followed by the king rubbing it around with his dick. "But do be a gentleman. He's been penetrated, yes, but not enough that he's as loose as I am, so I'll just pour a bit of this and you will be good to go."

"Understood," Nacho hummed, using the tip of his cock to spread the lube poured onto the older pinkette's asshole around before palming his rear and the base of his cock, pushing in slowly and as gently as possible, feeling him tense and clench on him. He was only halfway in before he discovers that Arthur's boyfriend has fully relaxed on him and that he was sliding further in with no issues, but with a pleasant feeling that he couldn't help but get more of by firmly grasping both cheeks and pushing in completely.

"Hmmh!" Sheldon moaned on the twink's cock, as did the latter upon being penetrated balls-deep. The canine responsible for that felt really girthy and long. Longer than he was used to when bottoming. He heard him mutter his catchphrase before he was pushed into repeatedly at a relatively slow pace, feeling him slide back to the tip, and back in as deep as before. "Mmmh..."

"You like that, Shelly?" You may have started out faster than this but you went just as deep too." Arthur said, sighing from the sensation of his mouth coming down on him with more effort than before with the king giving him all ten inches back and forth. "But after that, your performance wanes, and disappointingly so, meaning I have to do all the work and be too tired to do anything else." He meant every word, despite not being very upset. He forgave Sheldon and this was his way of showing it, by having someone bigger than him dick him down as a way to teach him a lesson to remember for later.

"If you're tired or occupied with other matters, then say that, don't just go through with giving it to me and not have the energy to make it worthwhile, you know." He emphasized by sinking himself flat against the fondue-haired man's face, sliding his shaft along his tongue that undulated under him as Nacho's deep thrusts rock him back and forth, pushing him to suck him off more. "So now, you will learn to know better in my place. Mind going a little faster, my good sir?"

The increase of the canine's pace behind him had Sheldon bucking back against him, as his thick girth stretching him whilst now periodically striking his sweet spot has him surrendering to his influence. He hasn't bottomed in quite some time, and to do it again with a different man who outsized him was even better than he was counting on. He hadn't counted on this being the lesson from the get-go since coming home, but now he doesn't mind. If this was the lesson he had to be taught to do better in bed, he was all for it, considering the lack of sense it made to him.

"Mh-Mhmmm, eeenhh~." He groaned, darting his submissive eyes up toward the Noxian while sucking harder on his cock, giving him an apologetic look, and even trying to say so with him in his mouth but from Nacho's actions, it was proving difficult, but the pinkette knew well enough what he was gesturing. "Mmmh!"

"I know, I know, Shelly, I forgive you," Arthur hummed, laying back now to really fuck his mouth, holding his head firmly and musing his hair. "I'm not mad...ah...I'm just disappointed, is all. But I will admit one thing..." He trails off to moan again, the mouth of his lover the best thing he's ever felt. He's rarely taken him in his mouth before and he couldn't deny that it was the next best thing.

"Hmmhmm, take it all the way in..." The king behind him growled softly, freeing one paw to harshly smack Sheldon's left cheek, leaving behind a pawprint while deeply pistoning his cock inside of him with semi-rough snaps of his hips. He didn't feel too different from Denzel or any of his friends with benefits he's topped in the past, but with the way he was pushing back against him at his current pace, he couldn't help but increase the force of his movements. "Just like that. A-ahh."

The next rough thrust inside of Sheldon had him groaning on Arthur's cock as his twitched and he spilled his load all over the bed. The latter noticed him jolting in his grip, prompting him to snicker. He looks down and sees that the hybrid's hair had taken on a magenta shade whilst his dazed expression told that he was completely out of it from being given dick from both sides for such an extended period of time. He may have been more of a bottom than he looked, but he topped just as often, and he could never get that look out of the man no matter what he did. Of course, an anthropomorphic dog got it out of him easily, and he couldn't help but feel jealous.

"Ooh, fucked to an orgasm already? It's only been seven minutes, babe" Arthur noted with a laugh, watching his guest just bottom out the love of his life while matching his pace within his mouth. "I could never get that much out of you until now."

"Through me!" Nacho grunted in the midst of his thrusts. His balls slapped against the Noxian hybrid's that echoed in the bedroom coupled with his paws occasionally smacking his reddening ass if the force of his hips slamming against him weren't doing the job enough. "I'm that good, after all." He spread his legs to better his thrusts, panting along with the teen that made good use of his lover's mouth, having gone at it for long enough that the smooth, yet partially tight feel of his ass was taking a toll on him.

Sheldon's moans were barely coherent by then by the 'lesson' he was being given, what with his bottom's throbbing dick tapping the back of his throat. Being used from both sides has taken the stimulation of his nerves to new heights. He was surely going to remember this moment, and pretty much ask to be done this way more often. He truly has discovered a new kink today, that was for sure. 

He was so filled with bliss that he doesn't acknowledge Arthur's warning about him being close before his mouth was overrun by the sudden rush of cum and the feminine squeal that filled his ears. It was apparent he had cum in his mouth, and he was already drinking it down as the schlong shafting him was now his main focus.

"Oh, shelly! Oh! F-fuck, baby!" Arthur shuddered, keeping Sheldon pinned flush to his crotch as he was stimulated during his orgasm. "Aaa-aaah, fuck...nnngh!"

"There you go, Sheldon, take your boyfriend's spunk!" Nacho growled, watching it all play out as he was balls-deep in the hybrid, grinding against him while holding firmly onto his hips. "Because I'm about to give you my own~!" His snarls quickly become moans when he pulls out and thrusts back in, going slow and deep as he approached his big moment one push of his hips at a time. 

"Gi-give it to him," Arthur moaned, still thrusting into Sheldon's mouth. "Fill him up for me~."

The canine groaned shakily, hilting himself completely inside the hybrid and tightly squeezing his hips as the man beneath him let off from the teen's cock to cry out loud. "I will! Gonna...gonna...fill his guts- HnnNNNNG!!!"

"Oh, GoOooOOoD!!!" The pinkette bent over yells, his eyes rolling up and his glowing magenta hair flaring, spiraling out of control as his anal orifice was pumped full of canine sperm as the latter seethed through clenched teeth, holding him close during the process. His spunk spilled like a broken dam, coating his anal walls with only a few drops spilling out and dripping down his balls. Both men panted, releasing numerous orgasmic sounds with Arthur sitting back and enjoying the show, biting his lip with a lusty smile.

"Fantastic, baby," He hummed.

When the ordeal was done and over with, Nacho's grip on Sheldon finally diminishes and he slowly pulls out, exhaling softly in the middle of his heavy panting, his cock coming out covered in a mixture of sperm and some lube left over. The tip pops wetly out of the half Noxian's ass, revealing the hole to gape a couple centimeters wider than before penetration, giving him a nice eyeful of his handiwork that flooded his insides. He chuckled when recovering, patting the man's tender rear and straightening up. "King Nacho likes."

Ugh, he can so say something else. But it's his main go-to for things that interest him. 

"you've done a nice job, my liege, well done," Arthur said, patting the well-fucked man on the back who was still with his ass still in the air. "How was it?"

"A new experience, that's for sure," Replied the canine before he licked his lips peering back at Sheldon's gaping asshole. "Especially since I've made his ass a tad bit wider for future uses. You're free to take a look if you're interested."

"Is that so?" Arthur hummed in question, sliding out from under the older man and getting off from the bed to indeed, see for himself. "Oh, goodness me." He gasped upon seeing that his lover's pucker was indeed gaped, and leaking the ruler's cum freely. He saw no tears, meaning that the lube he used was the right kind, and that he would need to get a bigger dildo for him to use. "You weren't holding back."

"As I never do, how else would I have gained a reputation of being everyone's 'daddy'?"

The word had the teen shivering with desire, but figured he'd let him be for the time being before reaching up to pet the chihuahua who leaned down to let him, given their height, he dwarfed him by three feet after all. "I see. Well, I hope you've enjoyed your stay so far. Thank you so much for your time."

He was then rewarded with a cheek lick from the ruler before he left. When he did, the teen turned back to the pinkette, who was on his side, fast asleep and snoring quite loudly. It seems he was actually tired when he came back. And the spitroasting had pretty much tuckered him out as it seems. "Huh. I was just about to ask if he's learned something out of this, but oh well." Arthur shrugged upon finishing, going to peck Sheldon's cheek before leaving to fetch some cleaning supplies, the blanket he came all over was dry-clean only. Great.
