Next he tried to get the pacifier gag out. Not that it would matter much. Mommy would probably put it right back in. As expected, it was impossible and he only noticed Mommy was watching his futile attempts when he heard the amused giggle.

"I would think that a little boy who's already in trouble would be on his best behavior."

Spike resigned himself to sucking on his pacifier.

Rarity dated around for a while, brought different people home for the night and Spike hardly saw them and almost never actually spoke to them.

Until Applejack that is. When Applejack came into their lives, everything changed.

She had been endeared by Spike at first sight. Spike was the cutest thing she'd ever seen and she fell in love with the way the boy liked to be humiliated. She loved the idea of the sweet young boy toy Rarity kept, to take care of and love in her own twisted way.

She was attracted to Rarity for different reasons, both of them shared a love for power. They admired each other's intellect and maturity, found comfort in each other's headstrong personalities and driven attitudes.

But having Spike in their lives filled a gap that neither could ever have imagined they'd have in their relationship.

Dominating the sweet boy sometimes got them both so riled up that punishing him was becoming one of their favorite kinds of foreplay.

And Spike could not bare how attractive the two were. If Rarity could command a conversation, Applejack could command a room. Applejack was intimidating in a way that Rarity wasn't, was stricter and scarier and Spike loved it. It satisfied a deep need within him that had been there for too long and that he had thought might never be filled.

Rarity, strictly a top when dating women, was now submitting to the woman in a way Spike had never imagined would happen. But somehow Applejack had managed to change even that.

Applejack sometimes even told Rarity what to do, and Rarity listened. (Something Spike found unimaginable).

For that reason, Spike didn't argue at all when Applejack started laying down new rules.

The first of which was that she expected to be called Mama.

Mommy had caught him right before he reached the toilet and hadn't been pleased with Spike at all. He had been placed straight into his bouncer and hadn't been let out since. He was working hard to hold it but as time passed it was only getting more difficult.

Spike thought he couldn’t possibly have felt more like a stupid baby than at that moment. The pacifier gag certainly was not helping and he imagined it made him look completely infantile and helpless. It was humiliating but comforting and he couldn't decide whether he was turned on or mortified. It was somewhere in between and the cage around his cock meant it didn't matter which one it was since he couldn't do much about it either way.

But then he felt it, and he heard it and he was pretty sure Mommy heard it too. The pee escaped him with a sharp hiss, having been held for so long, the liquid released with a force and he could feel the padding around his crotch catching it and filling, growing heavier. The diaper expanded beneath the straps of the harness that held it tightly against him and he whined, wiggled, tried to make space for the way it was swelling around him.

And then something harder began pushing out at the back, into the seat of his nappy. It was warm and there was no space for it to go so it spread inside his diaper, making it feel heavier and uncomfortably sticky. It didn't smell great.

The worst place to be with a messy diaper was in the bouncer harness. It held the diaper against his body, forced him to feel all the warm wet mess against his skin and there was no way to free himself or lift himself out of it. It was the most degrading and humiliating thing he could imagine, which is probably why it was a punishment.

Warm, wet, messy, stupid, baby. The words cycled through his head like a mantra.

“Aw, Spikey Wikey, did you finally make a mess sweetheart?” Mommy sang.

Without meeting Mommy's eyes, Spike tried to hold onto the bouncy ropes to keep himself still in the swing.

The sound of the front door opening and closing travelled through to the living room and Spike could feel his heart hammering in his chest, nearly louder than the sound of shoes being removed at the entrance.

Mama walked in wearing her usual overalls, looking confident, self-assured, gorgeous and more dominating than ever. Spike felt emasculated by her mere presence and he kicked in his swing, not knowing what he wanted to achieve by it but trying anyway.

"How's my beautiful girl and my favorit' little boy hm?" She greeted, hanging her hat up on the coat rack and loosening her Timberlands as she made her way into the living room. She rolled up her sleeves to just below her elbows and Spike could see that Mommy's eyes were drinking in her delicious appearance. Spike's eyes were doing the same.

Mama first headed to couch where Mommy sat. She fell into the seat next to her lover and the two shared a tender kiss but stopped just as it got too heated, Mama pulling away to apologize for being late. They looked so good together. So lean and pretty.

Then Mama walked over to the bouncer. She smelled like expensive wine and the apple blossoms in her family's apple orchard. Brushing Spike's hair back, Mama placed a soft kiss on his forehead, making him blush despite the rest of his predicament and bondage.

"Howdy sugar-cube," Mama said, and then her nose crinkled and Spike wished he didn't know why. "Uh-oh. Does somebody needa change?"

Spike's bare feet swung shamefully and there was an awful squishy wet sound from his crotch. He needed a change, but something about not being given one was degrading in a way that he hated to admit he liked. "We should get ya changed, huh kiddo?" Mama said, reaching towards the buckles to free Spike from the bouncer and Spike felt a small twinkle of hope.

“Just a second darling, I think our baby has something he wants to tell his Mama," Rarity said, throwing her head back to finish off her wine. She hadn't brushed her hair this morning, making her look a bit more rugged than usual. Spike liked it.

Mama's hands stopped before the harness could be opened. “Really? Do ya need to tell Mama somethang, sugar?"

As reluctant as Spike was about having to say anything at all to Mama in this situation, he nodded, knowing it was inevitable.

He expected Mama to take out his pacifier so he could tell her what happened today, but instead Mama just cooed at him. "Go on sweet-pea. I'm listening," she said, pseudo-sweetly, stroking Spike's gag-rounded cheek with the back of her hand.

Spike let out a plaintive little whine but Mama merely waited, with expectant eyes. So Spike tried, as humiliating as it was, to explain that he had been naughty today and all that came out was muffled little groans and muted mumbling.

Mama nodded along patronizingly, as one would so with a real toddler who was baby-babbling, before turning to Mommy for a translation. "

"Is that why mah little baby is in his bouncer?"

Spike nodded, mouth sadly still full of rubber gag.

"What did mah little boy do to get in so much trouble hm?" Mama asked, examining Spike's flushed face with her penetrative eyes. Spike stared back at her, eyes wide and pleading but Mama remained inscrutable.

Mommy answered from the couch, "Spikey tried to use the toilet like a big boy."

"Ya don't say? I thought our little boy knew better than that."

Mommy looked at Spike with a raised eyebrow as she put her wine glass on the coffee table. "You want to tell Mama what happened after that?"

Spike shook his head no, eyes wide and silently pleading with Mommy not to tell.

"Sugar-cube, is there more? Is Mama going to be mad?" Mama asked, eyes darkening as she held Spike's gaze with intent. Spike shifted a bit in his mess which was a mistake and he winced, trying to ignore the hot feeling of soft shit around his groin.

"Guess who called me Rarity today?" Mommy said, tone lighter than Spike thought the incriminating sentence warranted.

Mama finally turned to look back at Mommy and then her dark eyes were on Spike again. "Not our sweet little boy?" Mama whispered like it was an awful secret and Spike's head fell forward, no longer able to look at her surprised face. But Mama wouldn't let him escape and used a finger to lift the boy's chin so that their eyes met, both of them in vastly different positions of power. Spike could smell Mama's breath when she leaned in contemplating,"Maybe we should start spanking him, hm? Maybe we haven't been disciplining him enough."

Mommy hummed in thought, clearly pleased by the idea but Spike whined, shaking his head no. He didn't want to be spanked. Would they spank him? He'd be good! He wished he could promise out loud that he would be good but little boys didn't get to decide their punishment, did they?

"Seems like someone needs a reminder of the rules, hm?"

Spike squirmed. Mommy was hottest when she was laying down rules. Even if she was pretending to be mad about something trivial.

"Try keep it down Spike," Mama said gently, as she took a seat again beside Mommy, arm stretching out so the other woman could curl against her. "The grown ups are going to watch a movie and discuss your punishment. And then maybe we'll change you after the movie is over okay?"

What movie? They hadn't even started watching a movie. How long away was that?

The opening titles had barely started and already Mommy's jaw was being held delicately in Mama's hand, guiding her lips into a kiss.

Their bodies moved together in feminine harmony, kissing and moaning with familiar intimacy. They knew where to touch each other to get the loudest whines and they knew how to position themselves so Spike had the most explicit view.

Confident hands pulled at clothes, two dominant women undressing without hesitation. There were no trembling fingers. They both pushed against each other with certainty, wanting to feel more, wanting to be touched.

There was complete self-assuredness in the way Mama held onto Mommy's ankles and pulled her legs wide. Mommy's fingers curled into the couch seat but her eyes were hungry as she urged Mama to get a move on and touch her.

They were both sweaty, and Spike was entranced by the way the muscles rolled across their glistening backs and arms.

The movie was ignored, and at first glance it would appear as if Spike was too. But he was as much a part of the intercourse as he wasn't. Every move and every groan was exaggerated, part of an exclusive show made for their little chastity boy as a punishment.

Even when it seemed like he was forgotten, like they were both caught up in their own pleasure, Mommy would meet Spike's eyes over Mama's shoulder and moan loud and purposeful.

The two women enjoying each other's bodies in such an adult way only made the contrast between them and Spike in his messy diaper more obvious.

Eventually Spike couldn't keep quiet anymore. He wanted to touch! His cock was hurting inside its metal cage and the wetness inside his diaper was growing cold. He whined around his gag, high and helpless.

Mama didn't stop when he spoke. "If ya need to go again ya can go in your diaper baby. It can hold an awful a lot more, Mama promises."

It already felt full and wet and gross. But he couldn't argue with his gagged mouth so he just kicked his legs. To his chagrin, the stretchy ropes bounced him up and down and he made small noises of complaint behind his babyish gag.

"Aw sugar-cube. Ah know. It's not nice. But that's why it's a punishment. And we know ya love it," Mama grunted as she penetrated Rarity's entrance with her fingers, "Love being our helpless little baby boy. With two hot mommies, don't ya?"

It was true and they already knew it was true but somehow, saying it in words with the sole purpose of humiliating him was taking their sex to a new level.

Mama increased her force and speed, making Mommy gasp and tense. They orgasmed over each other with animalistic grunts and moans, nothing at all like Spike's whines and whimpers.

Mama switched off the movie that no one had watched and finally helped Spike out of the bouncer. They cooed at him, sandwiched his body between their sweaty ones, not caring for the dirty squish of his diaper. They kissed his face all over, told him what a good boy he'd been while they carried him to the changing table in his room.

They didn't take the gag out because they said he looked too cute and sad with it and they wanted to see him cum with his daddies' help while sucking on his pacifier like a helpless little boy.

It would help him learn respect, they said. And boy did Spike feel respectful when Mommy finally pulled off his dirty diaper and cleaned him up with pretty-smelling citrus wet wipes and baby-smelling talcum powder.

He was so relieved to finally be out of the mess and rid of the smell and he couldn't help but giggle when Mama came over and blew a raspberry on his tummy.

"There's our happy little boy," Mama smiled, pleased with his response. "Happy to be in a clean diaper, aren't you?"

Spike nodded. He was indeed relieved. Mama unlocked the metal chastity cage and was kind enough to play with Spike's excited little cock.

Mama praised him for taking his punishment so well, reminded him of the rules, reminded him that little boys weren't allowed to use the toilet.

"Such a naughty little boy Spikey Wikey, getting hard in your messy diaper watching your mommies do grown up things," Mommy cooed as if Spike wouldn't understand what she was saying anyway. And Spike was so so close that the words indeed hardly penetrated his mind.

But his Mama leaned in close, breath hot against his cheek and her hand worked Spike's cock faster and harder. "You'll never be allowed to do that sweet-pea. You're much too little."

And Spike came all over Mama's hand, pacifier still in his mouth as he groaned.

"Aw look at mah little boy making such a big mess. Don't worry, we'll clean you up baby boy."

They did just that. And when Spike was all snug in his dry diaper and buttoned up into a tight cozy onesie, they tucked him into his crib, each woman leaving a kiss on his forehead and turning on the night light before exiting with light footsteps to enjoy themselves upstairs.
