With an Extra Shitty Cake

“Oh, fuck yeah,” moaned Starlight Glimmer as she bounced up and down on the thick cock buried deep in her pussy. Sunburst grunted from underneath her as her flank slapped down into his lap every few seconds. Her tight snatch a perfect fit for his turgid dick, and his entire length was tingling at the constant contact with her inner walls.

The stallion grunted as the unicorn rolled her hips. “I’m… I’m gonna cum soon,” he warned as her tight pussy milked his cock.

“Quick,” Starlight said hurriedly. “Put it in my ass! I want you to cum inside!”

Sunburst was more than happy to oblige this request, and he swiftly lifted his marefriend up and off of his lap to reposition his throbbing member. His flared head pressed up against the tight rosebud of Starlight’s plump anus. Using her copious amounts of pussy juice as lube, he gently pushed against the hole until it reluctantly spread around his cock and he sunk into her dirty depths.

Starlight let out a long, low moan as her ass was penetrated. The stallion’s penis slid into her ass slowly and gently, but it still wasn’t very long before she felt herself bottom out on top of his lap.

The unicorn let herself get accustomed to the sensation of the large cock in her ass for a few moments. She knew what was going to happen next of course, because she had planned it. Starlight had felt her coltfriend’s dick push through the surprise she had left there, and she knew that he was going to absolutely love it.

She lifted herself up, dragging her sphincter all the way up the stallion’s length until it hit his wide flare. Starlight pushed lightly as she did so - she wanted to make sure that her anus wasn’t so tight as to drag all of the mess she had made for him back up with it.

Sunburst’s eyes widened. A thick film of brown muck had clung to his penis as Starlight lifted herself off. He could feel her anus push outwards around several larger clumps of her leftover shit as she rose, and he moaned as he realized she had most likely left a load behind in her ass when she had gone to the bathroom this morning.

“Oh, Celestia,” muttered Sunburst as he saw the filth coating his cock. “You didn’t clean yourself out?” His dick somehow felt even harder than it had before, and it throbbed hard.

“Ungh, of course not,” Starlight grunted as she lowered herself back down onto his dirty member. “I left some inside for you. I thought you’d love it.”

“Holy shit I do,” he muttered in a shaky breath as he watched her beautiful ass glide up and down on his lap. “I fucking love it.” He could feel his balls tense up as he prepared to unload himself into her ass, and he let out a low whine as his orgasm approached.

Starlight felt the increasing fervour of his upward thrusts, and she smiled. “You gonna’ cum?” she asked.

“Uh huh,” grunted Sunburst in reply.

A devilish glint appeared in her eye as she looked back at him. “And what do we say when we cum?”

“T-thank you,” stammered Sunburst as he felt himself sail over the edge. “...mommy!”

Starlight smiled and slammed her ass down on the stallion’s cock just as his head started to flare deep inside of her. A jet of warm spunk fired off into her dirty ass, painting the inside of her rectum white with Sunburst’s cum. She moaned as she felt herself getting filled with his seed, and she shuddered as her own orgasm overtook her.

Her anus squeezed around the thick intruder as her pussy quivered in her climax. A thin drool of milky liquid oozed out of her snatch and dibbled down onto Sunburt’s plump balls as they emptied their load inside of her.

Their simultaneous orgasm died down after a few moments and Starlight pulled herself off of her coltfriend’s cock with shaky legs. The prodigious member slipped out of her with a wet slurp and draped across his stomach as it softened. Starlight gently pushed the creampie out of her ass, and a dribble of off-white spunk drooled out of her gaped butthole. The semen drizzled across Starburst’s softening cock and mingled with the brown, anal sludge that slicked his length. A weak fart burst out of Starlight’s ass as she pushed, and sent a glob of brownish cum onto the stallion’s chest, and he laughed weakly.

“Wow,” he said, breathless. “That was hot!”

Starlight smiled as she turned back around. “I’m glad you enjoyed your first birthday gift, sweetie,” she said as she leaned over him to kiss his cheek.

“M-my first?” Sunburst asked as his eyes widened.

“Mhm,” Starlight said with a coy grin as her hoof traced circles around his barrel. “Your next one is coming later today, but I have to go out and pick it up.” Her hoof dipped down to his penis before it could fully slip back into its sheath and swiped some of the gross residue off its length. She brought it up to her nose and sniffed it curiously, before bringing it to her mouth.

“You don’t have to-” Sunburst began timidly, but trailed off as Starlight gave her dirty hoof a lick. She closed her eyes as she registered the taste of her own anal slime mixed with Sunburt’s cum before she swallowed. “How is it?” asked the stallion quietly.

Starlight smiled at him. “Not that bad,” she said. “I’m getting used to the taste.” She stood up off of the bed. “I’m going to need to for later, anyways,” she said quickly as she stretched her legs. “I’m gonna go wash up and get ready to head out.” She planted another kiss on her coltfriend’s cheek before turning away and heading towards their bathroom, keeping her tail hiked up high.

“Okay, Starry.” Sunburst watched her walk away with his half-lidded eyes never leaving her gaped little asshole. “Have a nice trip- wait what do you mean later?!” he called out after her, but she had already shut the bathroom door.

Starlight being gone meant that Sunburst had the entire rest of his morning to think about their wake-up sex and exactly what ‘later’ meant. He was embarrassed to admit that the ideas made him more than a little horny, and probably much too excited for his marefriend to return.

But that was still hours away, and Sunburst himself had work to do, so he decided to make himself busy. And so the hours passed slowly, with only a few breaks in between for some dirty fantasies, and eventually, the afternoon came.

“Sunny, I’m home!” called out Starlight as she came in the front door.

Sunburst quickly got up from the chair in the living room and made his way over to the entrance. “Was your mission successful?” he called out in playful reference to what she went out to do.

“Sure did!” Starlight said as he entered the vestibule and gestured to the pony standing next to her with a downright wicked grin. “Here’s your second birthday gift, Sunny.”

Sunburst’s eyes widened. “M-mom?” he stammered out.

“Hello, Sunny Bun,” Stellar Flare said warmly as she strode into the room. “Happy birthday!” She nuzzled into his side and planted a wet kiss on his cheek.

The stallion blushed and leaned away. “Uh, hi Mom,” he said. “I didn’t know you were coming.”

“Of course!” the older mare said chipperly. “I wouldn’t miss my little stallion’s birthday for anything! Besides, as Starlight said, what better birthday gift could you get than I?”

Sunburst’s blush deepened at the connotation of his mother being his ‘second gift’ of the day. Starlight knew of his more unorthodox fantasies, particularly towards his mother. After all, she made him call her ‘mommy’ every time he wanted to cum. So he couldn’t help but see an underlying connotation to her delivering Stellar Flare as his ‘gift.’

“Oh, uh, of course,” he said as he glanced back at his marefriend. Starlight’s conspiratorial smile did nothing to ease his nerves. “I just thought that Starlight would tell me that you were coming. I didn’t know.” His eyes flicked back to his mother, and his anxiety rose as he saw that she too had a similar smile on her own muzzle.

Something was not right here. Those two mares were planning something, and it made Sunburst nervous. His mother also looked distinctly uncomfortable. Not emotionally speaking, but physically. As she trotted about the living room talking to Starlight, her hind legs kept shifting. They crossed over one another, and her dock was completely flattened against her plump flanks. If Sunburst didn’t know any better, he would assume that she really needed to use the bathroom.

Starlight looked similarly uncomfortable, but to a lesser degree. She was doing a much better job of hiding it than Stellar Flare was, at least. Her eyes, however, kept darting to Sunburst and back, as if making sure he was watching. And then, when their eyes met, she lifted her tail slightly and let out a low, sputtering fart.

The stallion’s eyes widened as the quiet sound barely reached his ears. Starlight’s tail quickly flicked back down as soon as the flatulence had been released, and his mother seemed to take no notice of the quiet fart. The faint scent of her anal air quickly reached his nose, and he did his best not to obviously inhale the fumes as much as he could. Below him, his cock began to slip out of his sheath slightly, and he put one of his rear legs forward to hopefully hide the show from his mother.

And then Stellar Flare farted.

Unlike Starlight, she seemed to make no effort to hide it or conceal it whatsoever. Instead, she spread her hind legs slightly, lifted up her tail to reveal her quivering pucker to Sunburst, and then let a loud and wet fart rip out of her tailhole. She kept her tail raised afterwards to let her son watch her anus flex a few moments as another burst of gas escaped her tight ass.

Sunburst could not tear his eyes away from his mother’s pert little butthole, even as she turned her head around to look back at him. Her tail flicked idly as she smiled, but she still did not lower it to cover herself up at all.

“See something you like, Sunny Bun?” she asked. “Or should I say, smell?”

“Uhhh,” was all that he could think to say as his penis fully slipped out of his sheath and flexed painfully against his barrel.

“Ohhh, did Mommy make her baby horny?” Starlight teased as she sidled on up next to her coltfriend. She reached under him with a hoof to give his turgid member a few teasing strokes.

Sunburst’s eyes widened. “Starlight!” he hissed and shooed her away. “Not in front of Mommy- I mean my mother!”

“It’s okay, sweetie,” Stellar Flare said as she turned around to face him. “I already know about your… fantasies about me.”

“M-my what?” he asked as his face paled. His glasses slipped slightly down his muzzle as his ears drooped. “I d-don’t know w-what you’re t-talking about!”

His mom gently pressed a kiss to the side of his face and his cheeks quickly went from pale as a ghost to red as cherry in an instant. “If you want to know the truth, I think you’re a pretty handsome stallion yourself,” she whispered huskily in his ear, and he let out a startled yelp as her horn lit up and some warm magic fondled his hefty ballsack and throbbing cock. “And so well-equipped too!”

A louder fart from Starlight interrupted them, and Stellar Flare laughed as she pulled away. She gave her son one, last wet kiss on the cheek before she grunted at let out an equally urgent fart of her own.

“Would you like your cake now, Sunburst?” Starlight asked with a sultry smile.

The question briefly broke him out of his trance. “Cake?” he asked absently. “I didn’t know you picked one up.”

“Oh, I didn’t,” Starlight replied. “Your Mommy and I are going to make it for you right now. In front of you.” A ceramic platter suddenly hovered in front of them, and was placed down gently on the coffee table between them.

“Why don’t you take a seat, Sunny Bun,” Stellar Flare whispered sultrily as she walked over to stand next to Starlight.

Sunburst felt a gentle magic pushing him down to the floor, right in front of the living room coffee table. His penis sprung out in front of him comically, and he scooted forward to stuff the offending organ underneath the table in the hopes that the other two mares wouldn’t notice it. In his combined arousal and embarrassment, he failed to remember that the tabletop was actually made of glass and that both of them could see right through it as his flared head smeared precum against the underside.

They shared a giggle as both of them turned around and their flanks hovered over the coffee table - Starlight’s soft, well-sculpted rear beside his mother’s round, curvy bottom. Their tails were lifted up and out of the way to reveal their pert ponuts and wet pussies. Both of them looked to be incredibly aroused, and their plump clits winked in and out of their dripping snatches rhythmically.

“I hope you’re hungry,” Starlight grunted as her pucker flexed around another sputtering fart.

“Indeed,” added Stellar Flare with a groan. “We’ve baked quite a cake for you, Sunny bun.”

Then, Starlight’s anus began to flex again and Sunburst realized exactly what was about to happen. He watched as his marefriend’s butthole slowly spread around the head of a thick turd, and the hole stretched open around the advancing log. It was dark brown and mostly firm, and it kept its shape as it slowly bent down towards the plate below. A light film of grease smeared off of it as it passed through Starlight’s wrinkled pucker, and she groaned as she forced the thick rope of manure out of her rectum.

Its weight eventually betrayed it, and the turd broke off and fell to the plate with a dull thud. The rest of it slid out rather quickly and dropped on top of its former half. But Starlight was far from finished as the start of a second, knobby log quickly followed the first.

Sunburst had never seen Starlight poop before. As a matter of fact, he had never seen any other mare poop before. The scene unfolding before him was captivating. He watched intently and leaned in closer as his marefriend’s pucker spread around each new horseapple. He observed the way the tight ring of muscle gripped each, firm log as it slid out, and breathed in the scent of her fresh manure as it joined the growing pile of shit on the plate in front of him. His cock pressed up against the table as he leaned forward slightly, and his hoof wandered down to touch himself gently.

Starlight’s greasy ponut clenched around the sudden emptiness as the last log of shit finally slipped out of her. The unicorn had created quite a sizable mound of pony poop on the plate behind her, and she sighed as her bowels were finally empty. “Damn, I’ve been holding that in all morning!”

“That’s nice, dear, but now it’s my turn!” the other mare exclaimed as her round ass quickly nudged Starlight’s out of the way.

Stellar Flare let out a wet, bubbly fart as she began to push. Her anus quickly opened up and a soft, brown log of shit rapidly slid out. Loud, crackling farts accompanied the thin, smelly rope of poop as it squeezed out of her ass and coiled down on top of Starlight’s darker, firmer logs. It smelled a lot more potent than Starlight’s shit as well, and Sunburst’s nose crinkled at the foul odor. It wasn’t entirely unpleasant though - just different - and he was enamored by the scene all the same.

The older mare’s shit broke off into several small bursts, quickly losing its consistency until it was a semi-solid sludge that was pouring out of her asshole and onto the plate. The slop covered all of the shit like frosting on a cake, and Sunburst wondered if this was somehow planned to be this way.

His mother’s bowel movement ended with a sharp, wet fart and a loose spray of small fecal matter right onto his muzzle, and he leaned back in surprise. “Oops, sorry dear,” Stellar Flare called back to him sheepishly. “But, I’m guessing you probably enjoyed that anyways.” She was right, he did, and his tongue darted out to lap at the small flecks of shit dotting the front of his muzzle.

Cerulean magic slowly lifted a candle over to the pile of pony poop on the plate in front of him and gingerly pushed it down into the soft waste. Then, with a flash of Starlight’s horn, the candle sparked to life.

“Happy birthday, Sunburst,” Starlight said with a smile. “Now it’s time to eat your cake.”

The stallion needed no further encouragement. He was now fully stroking his cock as he leaned in and the hard member pressed up against the glass painfully. But he paid it no mind as his muzzle hovered over the steaming hot pile of shit in front of him. The smell was rich and earthy, and he pressed in further until his muzzle was practically in the mound of horseapples. And then, he parted his lips and extended his tongue.

“Wait,” said Starlight all of a sudden. “Aren’t you going to blow out your candle?”

Sunburst froze, and looked up at the two mares watching him. To be honest, in the few short moments that he had been leaning in, he had totally forgotten that he even had an audience. He blushed and pulled away slightly, puckering his lips to blow at the lit candle. It went out on the first try and his ears burned red as Starlight and Stellar both clapped loudly with sultry smiles on their faces.

“Good job, Sunny Bun,” Stellar Flare said. “Mommy is very proud of you. Now enjoy that cake!”

Sunburst whimpered as his cock flexed painfully in his grip at his mother’s words, and he leaned back down towards his ‘cake.’ His tongue reached out and made contact with his mother’s softer shit first. The foul, bitter flavor of pony poop spread across his tongue, and his body shuddered in a combination of pleasure and disgust. The soft, gritty texture smeared against his lips as he leaned in, and dug his tongue into the warm pile.

The stallion had, of course, tasted his own waste before, but he had yet to find anypony who would fully indulge him in this kink until now. Since admitting his fetish to Starlight, she would sometimes not wipe before sex and let him clean her dirty pucker, but the taste was always faint and fleeting. Digging his muzzle into a fresh pile of horseapples was entirely different though., and he nearly came as he took the first bite out of the mound.

His teeth carved through the soft, loose excrement of his mother before they came the firmer, denser logs that his marefriend had squeezed out. The unicorn pulled back, his mouth full of shit, and began to happily chew the scat down into a thick, gritty paste that smeared around his teeth and his gums. He couldn’t resist touching his throbbing cock as the bitter and foul flavors filled his mouth, and he began to stroke himself gently as he swallowed his first mouthful of pony poop.

“How is it?” asked Starlight quietly. The mare had leaned in slightly, her head directly above the steaming pile, and watched intensely as her coltfriend swallowed her scat.

Sunburst smacked his lips to clear some of the thick muck before he replied. “It’s… amazing,” he said in awe as he looked up at Starlight.

Starlight smiled softly at him. “What does it taste like?” she asked.

The stallion shook his head. “It tastes like…” he trailed off and shook his head as he tried to find the words. “It’s bitter, and slightly sour. There’s like, and underlying saltiness or sweetness to it, too. And M-mommy’s is slightly spicy.” He stuttered over the endearing moniker, but the wide smile on his mother’s muzzle encouraged him to continue. “But I like yours more. It’s firmer, and earthier, and almost feels like… like a brownie…”

Starlight looked between Sunburst and the pile of horseapples thoughtfully for a few moments. And then, she leaned down and took a small, tentative bite out of her own droppings.

Sunburst nearly came right then and there as he watched his marefriend taste her own shit. She let the small nugget sit in her mouth for a moment, and then her muzzle scrunched up as the full force of the flavors hit her. But she refused to spit it out, and let her tongue roll the feces around in her mouth for a bit longer. Eventually, she decided that the taste wasn’t nearly as horrendous as she thought it would be and bit down into it. The action released even more potent flavors from within the scat, but nothing more gross or nasty than the first initial bite. Her chewing sped up until the horseapple in her mouth was all but gone and she swallowed the paste that was left.

“H-how was it?” Sunburst asked, echoing her own question from earlier.

His marefirend looked back at him with a sultry smile on her face that slowly spread into a shit-eating grin. “Delicious,” she said with a wink. “I think I baked a good cake.”

“Okay,” Stellar Flare cut in. “Let me have a taste.” The older unicorn leaned in beside Starlight and took a generous bite out of the pile, making sure to get a good helping of both mare’s shit. She moaned as the disgusting flavors hit her tongue, and her eyes rolled back as she savored the filthy fudge. “Mmmm, that’s good.”

“M-mommy?” Sunburst questioned as his eyes widened. “You… you like…”

“Of course, Sunny Bun,” Stellar Flare answered as she swallowed her bit swiftly. “Where do you think you got it from?”

“Celestia…” Sunburst swore under his breath as his mother leaned back down into the pile of crap with Starlight right beside her. Their cheeks rested against each other as they eagerly took generous bites of the horseapples into their maws. Sunburst leaned in to join them and took his own healthy serving of scat.

The stallion was doing his best to hold back from cumming as the three of them quickly devoured the entire mound of shit. Their muzzles were each smeared with copious amounts of soft and wet feces, and their breath would probably stink of pony poop for hours afterwards. But as he licked up the last smear of Starlight’s poop from the ceramic plate, he couldn’t help but want more.

“You’re looking a little pent up, there,” his mother said softly as her magic moved the coffee table away and to the other side of the room. “Why don’t you let Mommy help you out with that?”

The stallion’s cock throbbed painfully at the offer and he groaned as a dribble of precum drooled from his cumslit and dizzled over his flared head. He watched as his mother approached and reclined back on the couch with her hind legs spread wide in an open invitation for him to take her as he pleased.

Sunburst got to his feet and reared up over his mother. His thick, hard cock slapped down against her wet pussy with a heavy smack, and she cooed in delight at the sudden, harsh stimulus. The stallion dragged his dick across his mother’s drooling slit and ground against her for a few moments before he pulled back and lined the tip of his turgid horsecock up against her waiting cunt. Then, he pushed in.

Both ponies let out simultaneous, loud moans as Sunburst entered the hole he was born from. His penis speared into Stellar’s warm, wet folds and he easily slid balls deep in a matter of seconds. “Mommy,” he moaned as he hilted into her, and his balls draped against her sullied anus.

“It’s a perfect fit,” the older mare whispered up to him with a smile. “Now fuck your mommy.”

Sunburst quickly drew the length of his shaft out of her pussy before slamming it back home with a grunt. His mother moaned as her son began to thrust into her, and she spread her hind legs wider to provide a better angle for the two of them. Her body rocked with each impact and her full breasts rocked up and down as his cock slammed deep inside of her. His balls smacked heavily against her dock and ass as he fucked her without any hesitation, each impact bringing him closer and closer to both of their orgasms.

Stellar smiled up at Starlight as the unicorn climbed on top of her. Starlight pushed her ass upwards and into Sunburst’s face as she leaned down to lock lips with Stellar in a dirty, deep kiss. Their tongues quickly met each other and swapped the wet, shitty muck between their mouths as they kissed, and Starlight wiggled her ass back at her coltfriend to get his attention.

The stallion’s eyes widened as his marefriend’s ass was presented to him. He wasted no time in pressing his muzzle up against her dirty, purple pucker and breathed in deeply. The scent of her shitty ass made him begin to thrust faster as he inhaled her foul musk as he pushed his nose deep into her wrinkled star. He moaned with delight as the brown hole opened up slightly to let out a hissing fart, and he took the opportunity to quickly huff her anal air before moving up and slipping his tongue into her still parted hole.

Starlight cooed as Sunburst’s tongue entered her ass. She pushed back against him as he orally cleaned out the inside of her rectum and lapped up whatever fecal residue was left inside. The musky taste of the inside of her ass pleased him as his tongue wriggled around and collected all of the fecal sludge that he could find. He pushed as far as he could, tasting the deepest parts of the mare’s ass that he could reach before he was satisfied that her colon was cleared out. Then, he pulled out slightly to run his tongue around the wrinkled ridges of her puckered star.

Bits of grime and fecal residue were lapped off of her puffy ponut as his tongue made rapid circles around her anus. He moaned into the dirty rimjob and enjoyed the taste, the feeling, and degeneracy of what he was doing as he orally cleaned her butthole. Each ridge of the nasty tailhole scraped against his tongue as he swiped the last of the filth from its puckered flesh before he pressed back in and lovingly made out with the unicorn’s musky anus.

As Sunburst ate out her ass, the unicorn felt another need growing inside of her, and she sighed into Stellar’s mouth as she relaxed her bladder. A pale yellow stream of piss sprayed out of her wet pussy and carelessly splashed against Sunburst’s chest. The warm shower dribbled down his front and fell to his mother’s lap as he tongued Starlight’s ass. Not wanting to miss a golden opportunity, he reluctantly pulled his mouth off of his marefriend’s now mostly-clean ponut and instead locked them around her pussy.

Salty urine flowed into his mouth and quickly filled his cheeks. He pulled away to gargle the yellow nectar before he swallowed it with a gasp and leaned back in for more. His tongue swirled against her parted lips and tickled her peehole before wandering down to press against her winking clit. Starlight moaned at the oral ministrations as she emptied her bladder into his mouth, which quickly overflowed and poured down onto his mother’s teats below.

It was the taste of shit and piss and the feeling of the warm urine mingling with his mother’s pussy juice that brought Sunburst over the edge. He hilted himself fully inside of his mommy’s cunt as his cock flared and a jet of spunk erupted into her waiting womb. His muzzle pushed forward as he came, and fully slipped inside of his marefriend’s wet slit as her urine stream slowed to a trickle, and he took the opportunity to taste the depths of her pussy.

Stellar Flare moaned as she felt her son cum deep inside of her pussy, and she let out a low cry as the feeling of the hot, fertile spunk flowing into her made her cum as well. Her body shook underneath the other two ponies as a weak jet of clear fluid sprayed out of her pussy around her son’s penis and slashed against his already soaked lap.

Sunburst’s balls slowly stopped pumping out cum into his mother, and he sighed as he nuzzled deeper into Starlight’s pussy. The unicorn began grinding back on his face as she rapidly sped closer to her own climax. The feeling of the stallion pushing his muzzle up into her pussy was what finally pushed her over the edge and she cried out as she came. Her entire body shuddered and a low fart spluttered out of her anus as she lost control. The warm flatulence blew right into Sunburst’s face and he moaned into her cunt at the feeling of the fart against his forehead.

The three of them eventually collapsed into a pile of sweat and piss and filth as they all panted heavily and tried to catch their breath. Starlight fell forward on top of Stellar Flare, and let out a weak moan as Sunburt’s muzzle slipped out of her gaping pussy with a wet pop. Released from his marefriend’s cunt, the stallion pulled himself out of his mother and fell back onto the floor in exhaustion. He watched as his cum began to flow out of Stellar’s gaped cunt and onto the fabric of the couch. Starlight was right above her, her own pussy slick with saliva and piss as the two mare’s breasts squished against one another as they lay.

“Damn,” Sunburst panted as his cock slowly retreated back into his sheath. “That…. That was hot…”

“Yeah,” agreed Stellar and she looked up at Starlight. “So you’re into scat now?”

Starlight merely nodded tiredly as her head fell into the crook of Stellar’s neck, who laughed. “Yeah,” she said quietly. “That was pretty fucking hot.”

Stellar Flare looked down at her son from around his marefriend with a satisfied smile on her face. “I’m glad you liked it, Sunny Bun,” she said sweetly. “But, if I’m not mistaken, there’s one thing left.” Both ponies looked at the older mare in confusion as a devilish smile came across her face. She looked back down at Sunburst. “What do you say when you cum?”

Sunburst blushed deeply and his ears flopped down. He struggled to meet his mother’s gaze as he practically whispered, “T-thank you, Mommy.”
