Obsidian tries to prove himself as a 'good boy' by following his Handler Pixel's commands- no matter how crazy they get.

Obsidian has never been one to fully step into the world of role-play, finding the whole thing a bit odd to pretend to be something that you're not. Until his wife Pixel introduces him to pet play, that is. When she finds him already in the mindset after coming home one day from work, she can't help but give in- and teach him a lesson when he gets naughty.

Contains: Pet play, F/M, transformation into futa, use of toys, oral, rim jobing, anal, pegging, orgasm denial, large amounts of cum, and a good boy doing good boy things.

"Sit! Beg..."

Pixel's body slumped against the wooden front door to her house as she let out a tired held in sigh, eyelids sliding shut. Yet another nine long hours spent bustling up and down at the fashion agency where she worked at, taking orders from her supervisor and slipping in and out of outfit after outfit until she couldn't remember which one was which anymore. She, for one, was more than glad that it was over, she was that out of it. It was when her eyes reopened did she see her husband's familiar brown satchel hanging stiffly on the nearby coat rack, and his usually filthy, mud caked work boots were surprisingly clean as they sat side by side underneath it. "He must have gotten the day off today," she thought as she wandered down the hall. To make sure, she called for him. "Obsidian? I'm back." There was no response, so she entered the living room, where a low squeaking noise caught her attention.

Rounding the corner, she blinked when her eyes laid upon the dark blue earth pony lying on his belly in the middle of the rug covered floor, dressed in nothing but black boxers and a bright red collar with a golden, jingling bell as his jaw clenched around the black dog bone shaped chew toy nestled under his hands, another squeak erupting from it. Oh. So this was what he was up to. A playful smirk pulled the corners of her mouth, eyes lidding. She knew that her partner took some time to warm up to different ways of 'play', and was intrigued that he was bold enough to get into this new mindset on his own so quickly. Deciding to see how long he would keep it up, she bent over and lightly patted her knees. "Sid! Here, boy!"

The stallion's ears instantly perked up at the sound of her voice, tail going a mile a minute before the rest of his body followed, hips swaying back and forth. His violet eyes gleamed as he happily held the toy in his mouth, bounding towards her until he stopped at her hooves, gently placing it down in front of her. His tongue lolled out of one side of his mouth while he panted, ears slicking back contently as she pet his head, scratching his scalp. The pastel blue unicorn smiled.

"Hi, buddy! Did you miss me?"

Sid yipped in response, and his tail seemed to be going fast enough to lift him up in the air if he tried.

"I missed you too. Have you been practicing your tricks?" At his bark, she rested her hands against her hips in a disbelieving manner. "Really? Let's see it then." One well manicured finger pointed towards his head. "Sit."

The male's legs bent as he shifted into a sitting position, tail rhythmically thumping against the rug.

Pixel nodded in approval. "Good." The digit then drooped to the floor. "Lay down."

And down he went, chin nestled in between his hands while he stretched his body out flat, looking up at her in expectation.

"Atta boy! One more." Her finger moved in a slow circle. "Roll over."

Obsidian teetered onto his back, stayed there for a few seconds, then flopped onto his stomach again. His tongue hung out once more as his ears lifted, chest puffed out as a near goofy grin crept onto his face.

The mare clapped her hands before dropping down to one knee. "Good boy, Sid!" She giggled as he came barreling into her arms, licking the tip of her muzzle. Her breath hitched when his lips suddenly pressed against hers, bringing them both to the ground as he inched closer, causing her to lean back until her head bumped against the hardwood floorboards. When the kiss broke, a warm, fond grin graced her features, lifting a hand to gently rub at his bare belly. "I love you too," she murmured softly.

A playful growl rumbled in his throat as he backed up a few paces, tail wagging again when he spun around in a few circles before picking his toy up and more or less bounded out of the room, glancing back to make sure she was following him. He had something to show her, apparently. "What is it, bud?"

Her heart sank when her eyes took in the absolute mess that the kitchen was in. Crushed water bottles that were pulled out of the open fridge gushed their contents onto the floor, the pantry was ransacked with boxes of food spilling this way and that, and the dining table cloth lay on the ground in a messy heap. Someone sure was busy. She turned to glare at the stallion looking up at her with a proud look on his face. "Obsidian…what do you have to say for yourself?"

His gleeful expression quickly shifted into one of guilt once he caught onto her sharp stare. His perked ears drooped, and his tail stopped its movements to settle in between his legs as he cowered. A saddened whine was the only sound that could escape him in that moment. Oops.

Pixel sighed. There was a reason why it was called "pet" play, and Sid was just contributing to make it as accurate as he could-within reason, of course. And, like a real dog, he was going to need to be disciplined to make sure he didn't do something like this again. And the mare knew just the way to do that. With a frown, she pointed to the doorway. "Go to the Den. I'll be there once I clean this up. Go on."

The male whined again, scampering out of the room, though secretly he was very, very excited to see what she had planned for his 'punishment'.

Sid's nostrils flared as he let out an annoyed snort. His new position- slumped over on a footstool with his round, bubbly rump on full display in the air- wasn't much of an issue, but the new additions his Handler had decided to put on him were. A black leash clipped around the ring on his collar, and the other end was tied snugly near the dock of his tail, so that every quick move from his head forced it to hike up even further than he normally would have liked. Worse still, his drooping prick was locked into a chastity cage, meaning he wouldn't be able to get himself off even if he wanted to. Well, he could, but it would be difficult, especially like this. Sucks to suck.

Feeling something suddenly brush against his exposed ballsack caused him to jump, unintentionally pulling his head towards his chest, the end of his tail now completely draping onto his back. When he was able to compose himself, a low growl shot towards an amused Pixel who was sitting behind him, tickling him with a feather. The unicorn then not too gently slapped the hanging orbs with her hand, earning a pained yelp as he squirmed, tugging at his dock even harder.

"That's what you get," she griped, though she rubbed at them gently with her fingertips to make sure he was okay. Feeling him start to lean into her touch, she smirked. Her pup was just too easy to please. "Be glad I didn't stuff your dry ass with Big Benson."

The earth pony gulped at that. Big Benson was a huge, vein covered black dildo that the mare had gotten as a gag gift from a coworker one year for Hearth's Warming. Too bad she never got to use it on herself. The behemoth of a dick was so thick, Obsidian was honestly surprised that he hadn't been ripped in two the first time she shoved it into him, and that was with half a bottle of lube coating it from base to tip. To try to imagine it sliding into his already tight tunnel without so much as a lick of saliva to help it along was more than enough to get him to clench his cheeks, shivers trickling up his spine. That would have certainly been a good punishment to whip him back into shape. But something told him his mate had other plans.

He quickly got drawn out of his thoughts when he felt her hands rest on top of his flanks, delicate fingers slowly dragging backwards until they reached the dark blue valley amidst two rolling hills of soft, jiggly flesh, pulling them apart. The cool air that caressed his round tailhole sent a bolt of pleasure straight down to his cock, biting back a grunt as it pulsed and throbbed helplessly within its binding. His ears perked when he heard her whisper, "You'll be a good boy, won't you Sid? You'll let me tongue your little asshole without any complaints, yes?"

He couldn't wag his tail, lest he wanted to risk accidentally choking himself, so he settled for gently swaying his hips, coupled with a soft purr as his answer.

"That's my pup." Her lips engulfed the tightened pucker, warming up with a few painfully slow licks across it before swirling the tip of her tongue all around its rim. Hearing his low, barely audible groan only prompted her to start sucking at it, noticing his hind legs were opening up wider as he leaned back more, nonverbaly asking her to start pushing in, to further tease his sensitive nerves. She complied for a few minutes, thrusting the organ into him at a quick pace that fizzled into a snail's one, only to pull free with a pop. The stallion's whine clearly displayed his dissatisfaction, but she merely patted the small of his back before standing up. "Don't move, ok? I just have to go get a few things. I'll be right back!"

The command was simple, but he found it hard to obey as he watched her own round rump jiggle subtly within the fabric of her jeans as she walked-no, more like sashayed out of the room. Her hips swayed like a pendulum, making it even more difficult to stay put as he wanted to pull the key keeping his stallionhood caged out of her pocket, throw the wretched thing aside, and ram her like the animal he was-or at least, the one he pretended to be. An eyebrow raised once the door closed behind her. What was she up to?

The stallion didn't realize he had dozed off until he felt fingers suddenly claw into his mane, roughly yanking his head up whilst something cold and hard was shoved into his mouth and buckles tightened straps against his cheeks. His body went into defense mode, head thrashing as he tried to get away, only to slip off of the stool and fall onto the floor with a thud. A sharp tug to his tail caused him to wheeze as his collar dug into his windpipe and it stayed there for a few seconds before it was released, coughing and sputtering as he struggled to catch his breath. Only when things got quiet did he open his eyes.

Pixel peered down at him with her arms crossed over her chest. "What did I tell you about letting your guard down?" she chided, though her voice was light. "Pup doesn't want to be separated from his Handler, now does he?" Watching his ears slick back, she gently pet his head. "Sorry for startling you, Sid. I just couldn't help myself, with you looking so cute and all."

The earth pony was getting ready to growl at her to show his disapproval for whatever made her take so long, but then looked down, suddenly aware that she wasn't wearing any pants, or panties for that matter. And he could see why.

A dark blue cock hung in between the mare's legs, seemly stirring to life from the other's awe filled stare. It rose to attention in a slow, almost graceful manner, curved tip nearly smacking him in the muzzle as it inched up by it. The unicorn's grin was wide when their eyes met. "Like it? The spell I used said it could be finicky, so I was just making sure that it worked properly before I tried it on you. You are the one getting punished."

Obsidian stared at the long, thick, smooth thing for a second or two, then back at her, repeating the motion a few times. He knew that his partner could rock his world with a strap on, but this? This was ridiculous. As much as he wanted to verbally protest how much that that wasn't going to fit in him, he remembered the one rule that the both of them agreed on whenever he was in this mindset: not to speak unless he was told to. And Celestia, was his brain threatening to betray him and end all of this for good. It was then that he noticed what was in his mouth-a spider gag. It held his jaw slack while his teeth clamped around the metal ring in its center, forcing his maw to stay open and allow anything- especially a dick- to slip in. His growl finally made its way out, though it was laced with a hint of worry.

Pixel gave him a reassuring look as she hefted the large shaft of mare meat up with a hand, slowly stroking its underside. "Relax, it's not as thick as Benson, so your colon is safe. But…" Her voice started to waver as her fingers glided faster, "I-mmm… I think I could use a good tongue bath, d-don't you?"

He snorted, but didn't seem to have much of a choice, she was going to ram his throat with or without the gag, so it was probably best to get it out of the way first. Plus, it would hopefully help keep his thoughts away from his own eager prick, which was pulsing underneath him even harder now. His eyes closed as he waited, nostrils filling with the sweet yet potent aroma of her droplets of pre as she got closer. At least she had that going for her. The second the tip pushed through the ring, his fur bristled in the best way possible. He wasn't able to close his lips around it thanks to the gag keeping them spread, but didn't mind it as the warm cock dipped into his wet pie hole, tongue hungrily slurping and wrapping around it like it was a lollipop, desperate to get a taste of her sweet sugar.

The mare gasped and shuddered, grabbing his head and letting her hips do the work as they thrusted into him, apple sized testes slamming against his drool drenched chin as she worked herself deeper towards the back of his throat. His mouth was always a delight to feel against her marehood, but it made her mind melt when it was being taken like this, without an ounce of mercy as she attempted to cram every inch down his esophagus.

His body rocked with her movements, the wet squeaks and squelches paired with low, passion filled whimpers and grunts trickling out of him coaxing her to go harder, breathing heavily when she suddenly stiffened, thick load launching into his belly. She sighed in content while carefully pulling herself out once she regained feeling in her legs, the limp dick dripping the excess of all it was coated with onto the floor.

"G-good boy," she shakily praised as she slowly lowered herself into a sitting position, smiling when Sid crept towards her, picking up the washcloth she had left behind earlier and cleaned him up, taking both the gag and leash off in the process. He curled up against her chest, tail wagging with a renewed vigor. He was happy that he made her happy, but he was in need of a break as well, simply content with breathing her scent. The unicorn lovingly gave him the comforting ear scritches and belly rubs he craved, but soon was giving him another command, this one causing him to twitch in his cage. "Clean me with your tongue and I may consider lubing up before I plow your naughty little ass." He didn't skip a beat, head dipping down to get to work at the task at hand.

A pleased whine slipped out of the male as his chastity cage was finally rid of him after successfully bathing his Handler's member from tip to base in a thin coat of saliva, earning more words of praise and teasing kisses to his forehead. His ears twitched when she told him to turn around, hiking his tail for emphasis. Something was telling him that she was ready to go again, surprisingly quickly after how much she had poured into him earlier. Still, he wasn't one to ask questions if he didn't feel the need to, and just went with what he was asked to do.

The mare's horn lit up, and he felt his fur tingle when she pushed the blunt tip of a lubricated butt plug into his rear, hind legs trembling while she slowly pistoned it in and out of his tailhole, making even more of a mess on the floor due to his freed tip drooling pre all over the spot underneath his waist. How he was able to keep it together for so long was beyond him, but it wasn't going to last much longer if she kept toying with him like this. To get his point across, he let out a yip, rocking himself against the plug to further increase the pull and push of the toy stretching his pucker.

Pixel beamed, easing it out and rising to her knees. "You want it now, huh? Ok, I'll bite. You know what to do if you want me to stop, right?"

Obsidian reached out for the bell that had been removed from his collar to prevent false alarms and rang it three times, shivering at the feeling of the mare's cock rubbing against his as she held onto his hips and let hers bump against his rump. There was no turning back now.

"Perfect. I'll start slow." It took a few tries, but she managed to pull herself back far enough to line up with his entrance, head steadily becoming engulfed in his heat as she continued to add pressure while pushing forward. The first couple of inches squeezed in without a hitch, but soon the stallion was hissing through clenched teeth when the shaft started to creep past the point where the lube coated his walls. A few times she wanted to stop and make sure he was ok, but he didn't make a move to ring the bell, so she had no other choice but to trust his judgement and keep pushing. When she finally hilted within him did she not bother with moving, instead rubbing at the earth pony's upper back with her free hand while the other kept her anchored. "You doing alright? You were hissing like a kitty earlier."

He didn't make any noise, but flicked his tail in confirmation: he was ok. Though she couldn't see it, he was biting his bottom lip hard, because where she was now, her tip was maybe a few centimeters from brushing against his prostate, and was worried if he tried to make a sound all that would come out would be words: loud, desperate, slutty sounding words. It was getting harder and harder for him to contain himself, but he had to wait. To please his Handler.

"Alright, if you're sure." Her first thrust was a little slower than she normally would have preferred, but she'd rather her husband be comfortable than be pushed to his limit too quickly. Speaking of which- she found it a bit odd that he had fallen so quiet all of a sudden. Normally he would have at least started panting or even shuddered, but apart from his tunnel tightening around her for a split second, there was nothing. Another shove, this time came a muffled grunt, but not quite what she was looking for. Then it clicked. He was waiting for her permission. With a playful grin breaking out on her face, she leaned forward, grabbed a fistful of his mane and pulled him back towards her to spear him even deeper, whispering into his twitching ear, "It's okay. You can let it all out. Speak."

The loudest, most feminine sounding moan Pixel thinks she ever heard come out of him tumbled from his lips, and the next thing she knew, he was pushing himself back against her even harder, as if all that was in him wasn't enough. And then came the begging. "F-fuck...O-oh Pix… turn me into your cumslut! Your cocksleeve! Rut me like the little bitch that I am! Fuck my ass until I can't sit for days! P-please!"

Well then. He didn't need to ask her twice. Her body went into overdrive, slamming in and out of his tightness like it was the only thing keeping her grounded. Their balls battered against each other with every stroke, each blow sending shockwaves up the stallion's spine while his back arched, now not much more than a pleading, moaning, trembling pile of nerves. His cock was drenching itself with its juices with all of the quick movements, though it still didn't hold a candle to the pure love on the floor. All too soon, his wire was coming to its end, and he felt his limbs shake even harder as his stallionhood filled itself with the seed that had been churning within him for who knows how long at this point. But before he could see stars flash behind his eyes, he had one last command to follow. "M-may I- oh- cum, Pixel?"

Her reply came with a final squeeze to his hips as she came undone herself with a cry, head buried deep inside flaring before unleashing a river of boiling spunk that gurgled and gushed as it flooded any empty space it could find. Sid followed soon after, shooting his ropes everywhere in front of him, hitting his arms, the bell, and the washcloth. The two were beyond exhausted, the unicorn not even having the strength to pull herself out while he toppled over, getting dragged down with him. They laid there motionlessly, the only sign of them still being conscious were their eyes blinking while they gasped for air.

Pixel reached out for the buckle of his collar once she could see straight, letting the piece of leather fall with a quiet thump. A light throbbing in her head signaled that the spell had run out, groaning as her shaft rapidly shrank and retreated back towards her nethers before disappearing into thin air. The weight from her sack had also lifted, so it took little effort to pull herself closer to him so their bodies were flush, nuzzling his sweaty coat. "You can come back now. Everything feeling okay? I think that's the first time I ever heard you beg like that."

A low chuckle left him as he rolled over to face her, pressing a hard kiss to the tip of her muzzle, and a soft one to her lips. "What can I say? I'm full of surprises." Lightly digging his fingers into where they touched her skin as he held her, his eyes narrowed. "However… I think you need to realize when your leaving a colt hanging. We are simple creatures with simple needs, and I think not having them met right away triggered my… ahem.. bitchy mode."

The female stuck out her lip in a dramatic pout. "Oh, boo hoo. Pup didn't get to make a bigger stain on the carpet when he wanted to, how tragic." Watching him shake his head caused her to giggle. "Hey, calm your tits. At least you still weren't tied to your collar, right? Maybe I should try that next time."

Obsidian couldn't help but gulp nervously at that. "Next time?"

"Yeah! Ooh, maybe I could throw in Benson and my dick in there. We could even do it tomorrow! And- I'm kidding, you big lug. I'll give you some time to rest before we can play again. How does that sound?"

He was instantly reminded of the searing ache that seeped into his cheeks, wincing when even the weight of his tail brushed against them. It was going to be a long week. "Wonderful. Simply wonderful."
