** 19 **

“Go on. Down on the floor for changey time. Let’s go, sweetie,” said Marzipan, laying a changing mat down on the floor before giving her niece a pat on the butt to get her moving.

Melody let out a little squeak as she felt her Aunt’s big, strong hand against the seat of her diaper, embarrassed that her Auntie would be able to feel the heavy pile packed inside. She instinctively reached back, her hands still locked in thickly-padded mitts as she tried to cover the obvious bulge protruding from her bottom. Though it would hardly matter in the end. Her Aunt Marzipan was about to change her out of her dirty Pampers right in the middle of the living room floor. She’d see everything that Melody was ashamed of, and there was nothing the younger mare could do about it.

Her anxiety-addled brain spun in circles, trying to think of some excuse to run away and hide in the bathroom again, but nothing sprang to mind through the dense fog that had enveloped her mind as she faced her greatest crisis yet. Of all the things she’d been through during her visit, this seemingly innocuous diaper change from her beloved Auntie scared her the most. She’d known her Aunt her entire life. She’d probably know her for the rest of her life. How could Melody bear the thought of her own family member seeing that which could never be unseen. The sight of her own naked crotch, stinking to high heaven, coated in filth for all to witness.

Melody whimpered a bit, and shrunk down into herself. She really didn’t want to get down on the floor to be changed, but she also didn’t want to hurt her Auntie’s feelings. Marz was trying her best to make her feel comfortable, and here she was recoiling from the most gentle touch, as though her Aunt’s love and affection meant nothing to her. Melody was conflicted. Ashamed of the fully-loaded diaper hanging around her hips, as well as the feelings of trepidation she felt toward her Aunt’s gracious offer to clean up the infantile mess she’d made in her pants. Thankfully, the dizzy girl snapped out of her brain fog as Marzipan brought her back to reality.

“C’mon, what’re you waiting for?” asked Marz, trying to hurry things along while still respecting her niece's boundaries. “You still got more to push out, or do you just enjoy having a mushy butt?”

“Nuh uh, don’t be gross,” Melody replied, immediately trying to discredit the idea that she actually enjoyed the warm, slippery feeling of her own manure against her backside as she hurried down onto the floor.

Suddenly, the blushing mare was eager to get the whole embarrassing spectacle over with, determined to prove that she wasn’t some brainless little diaper pooper with a kink for stink. She forced herself to go through the essential motions, lying down on her back with her knees up and her legs hanging wide open as if to say, “Hurry up and get this nasty thing off me!”

“Aw, don’t be so sensitive, kiddo,” said Marz, kneeling down to join her niece on the floor. “Mushy butts are just part of being a baby, and there’s nothing you can show me that I haven’t seen before.”
	
Melody hoped that was true, because she had a sinking feeling that the inside of her diaper was going to be a total disaster area. She’d been eating Fifi’s special recipes nonstop, and the massive dose of laxatives she had with dinner had seemingly cleared out a lot of bulk fiber that she’d been holding onto, if the impressive weight in the seat of her pants was anything to go by. She tried not to think about it, feeling her insecurities creeping back up as her Aunt tugged on the tapes of her diaper.

“W-wait!” said Melody, stammering slightly as she reached down to stop her Aunt from going any further. She couldn’t let her see the dirty mess she’d made, covering the waistband of her diaper with her mitts as she lay on the floor nearly naked. However, Marzipan wasn’t deterred in the slightest, picking up her niece’s oversized pacifier and popping it back between the girl’s lips before holding up a big floppy pony plushie to distract her.

“Shhh… Just relax, little one. Good little fillies don’t squirm during changie time,” said Marz, pushing the plush toy between her niece’s dainty padded mitts to distract her. “Just play with Princess Pony for a minute and it’ll all be over before you know it. Then you can squirm all you want, okay?”

Melody blushed, rendered speechless as she looked up at her Aunt who was smiling down at her with a look of patient understanding. The defiant college girl had been pacified, feeling genuine comfort as she clutched the soft plushie to her chest and nodded her approval to proceed. She’d never felt littler in her entire life than she did at that moment as she lay her head back down on the carpet and stared at the ceiling, waiting for her Auntie to get her all cleaned up.

Marzipan seized this moment of peaceful tranquility and quickly got to work, hoping to finish before her niece snapped out of the trance-like headspace brought on by her pacifier. Though, the big tough Clydesdale didn’t realize how big of a job she’d volunteered for until she finally peeled the girl’s diaper open, nearly causing a mudslide as the full weight of Melody’s post-dinner shit was unleashed.

“No worries, honey… Your Auntie will get you all cleaned up in no time. Just lift those legs up for me like a good girl,” said Marzipan, trying to psych herself up as she inspected the damage. Though, the tone in her voice wasn’t totally reassuring.

Melody hid behind her plush, covering her face in shame as she sensed the apprehension in her Aunt’s voice. It took all of her mental fortitude to lift her legs up and show off even more of her messy backside, but it was too late to back out now. Luckily, her Auntie had the size and strength to hold her legs up in the air with one hand, while using fistfulls of pony-sized baby wipes to scrape the gooey patina of filth from the girl’s undercarriage.

“There we go… Almost done… Just a little longer,” said Marzipan, trying to ease her big filly’s nerves as she wiped and wiped with seemingly no end in sight.

Though, the longer it took to get her cleaned up, the more Melody began to realize how good those cold little wipes felt against her warm bottom. All the wiping and stimulation had her feeling all squirmy again, but for a totally different reason, and she was no longer hiding her face out of embarrassment, but because she didn’t want her Aunt to see her enjoying something so dirty.

She had to bite down on her pacifier to stop herself from whimpering like a naughty little diaper slut as her pussy was wiped clean. Her Aunt was being very gentle with her most delicate areas, but it only made it tickle more. Despite her efforts to be sneaky, Melody groaned and arched her back slightly, rubbing her cheek against the soft fuzzy skin of the plushie that was pressed against her face. She was acutely aware of how silly she must have looked, but she couldn’t stop herself as she felt another cool baby wipe probing around her sensitive flower petals.

The content filly exhaled sharply as her Aunt cleaned around the top of her vulva, stimulating her clit just enough to send a wave of pleasurable sensations throughout her body. For a moment, Melody let her guard down, sliding the plush toy down across her neck and onto her naked chest, allowing the soft felt to rub against her nipples as she breathed heavily into her pacifier. As naughty as it was, she wanted her Auntie to keep rubbing her there, but she couldn’t work up the courage to ask for more. Unfortunately, that meant only a fleeting moment of divine sexual pleasure, but it was enough to get the pent-up young mare wet between her legs.

Melody felt lightheaded. Her cheeks were flushed, and her legs were trembling by the time her Aunt slid an extra-thick diaper under her butt and began sprinkling baby powder all over her glistening pink crevice. A moment later, she felt the soft padding of a fresh diaper hugging her powered crotch, enveloping her quivering sex-starved pussy, signaling that “playtime” was over for now. Melody was a bit disappointed, but as her raging libido died down a bit, she was relieved that it ended when it did. Any longer and she may have gone all in and begged her Aunt for more, revealing herself for the filthy pervert she was.

Of course, Marzipan noticed her niece’s not-so-subtle response to being cleaned up down there. The younger mare’s excessive gratification from even the slightest touch was obvious, but Marz was kind enough to keep her teasing comments about the girl’s twitching, wet sex to herself in the hopes that her niece would be less bashful next time she needed a diaper change. Marzipan enjoyed pampering her big diaper-baby of a niece, and didn’t want to send her running to the bathroom to cry.

“There, now doesn’t it feel good to be all powdered and padded up?” asked Marz, tickling Melody’s tummy before helping her up off the floor. “Let’s hurry and pick a scary movie before Fifi gets back and makes us watch something for babies.”

“Too late! I’m back now, and I say no scary movies before bed,” said Miss Fifi, injecting herself into the conversation as the big pudgy Basset Hound returned from the nursery with Melody’s purple pajamas in hand.

“Aw, come on. Don’t make us watch something lame,” said Marzipan, pouting like a moody teenager as Fifi stepped in and began helping Melody into her jammies.

“Don’t start with me,” snapped Fifi. “Melody is going nighty-night after movie time, so nothing that’s going to give her nightmares, or you for that matter.”

“That was only one time,” said Marz, rolling her eyes.

“Don’t care,” said Fifi, dismissively. “Pick something that’s appropriate for bedtime, or I’m going to choose the movie and you get diddly-dick.”

“Fiiine… I’ll pick something for babies,” said Marz, sticking her tongue out at the bossy hound the moment her back was turned.

Seeing that Melody was distracted by her Aunt’s hijinks, Fifi snapped her fingers to get the girl’s attention.

“Time for peejays, dear. Let’s get you ready for bedtime,” Fifi said, holding up a pair of locking plastic underpants.

Melody knew there was no point arguing after getting caught with her mitts down the front of her waistband earlier. She stepped right into them like a good filly and let Fifi pull them up over her diaper and lock them nice and snug, ensuring there’d be no unauthorized access.

“Very good, little one. You’ve earned a cookie,” said Miss Fifi, helping Melody into her purple jammies. “Just let me zip you up in the back, and I’ll go and grab us some snacks.”

“Is Marcus coming back?” Melody asked.

“No, he’s already in the crib. It’s just going to be the three of us tonight,” answered FIfi. “If you want a little friend to keep you company, take this.”

Fifi scooped the Princess Pony plush up off the floor and stuffed it under Melody’s arm before urging the overgrown filly to find her spot on the sofa. Then she disappeared into the kitchen to gather movie night supplies while Marz picked a movie. Melody watched from the sofa, cuddling with her plushie companion and sucking on her pacifier like a big dopey toddler. The warm cozy pajamas made her feel nice and secure, and she was glad to finally have some clothes on her naked body again, not to mention a clean diaper.

“Melody?” asked Marz, “Would you rather watch a boring movie about a kangaroo who goes to ballet school? Or an awesome movie about a bus that can’t slow down?”

“Just put on the damn ballet movie and sit down before Melody steals all your cookies,” snapped Fifi, returning from the kitchen with a stack of cookies for each of her favorite mares and a pony-sized baby bottle under her arm.

“Pfff… Fine, but you don’t know what you’re missing”, grumbled Marz as she dimmed the lights and took her spot on the sofa next to her niece.
	
Melody spent the evening clinging to Marzipan and being fed oatmeal cookies. She didn’t care about the movie, she just liked dozing off in her Auntie’s big strong arms while she sucked on her bottle. She wasn’t sure exactly what it was, but it tasted like milk with cinnamon and sugar, and it made her really sleepy, which is probably why Miss Fifi told her to drink it slow. Though, to her credit, she made it through most of the movie before falling asleep with her head on her Aunt’s lap. She only intended to rest her eyes, but when she opened them back up, the movie was over and Marz was tickling her neck, trying to wake her up.

“Hey kiddo, movie’s over, let’s get you to bed,” said Marz.
	
“What time is it?” asked Melody, brushing her mane out of her eyes.
	
“Bed time,” Marz answered, and took her by the arm. “C’mon, don’t make me carry you.”
	
Melody yawned and used her sleeve to wipe the drool from the corner of her mouth before being escorted down the hall toward the nursery. She leaned on her Aunt the whole way, feeling a bit wobbly thanks to the alcoholic baby formula she used to wash down her cookies earlier. Thankfully, they made it to the nursery without incident, where the nightlight was already on to guide her to bed.

** 20 **

Marcus laid in the crib, waiting for whatever movie they were watching in the living room to be over. He had no idea what they were watching, but the wolf’s sensitive ears couldn’t ignore the bass vibrating through the walls, keeping him awake. Marzipan and Miss Fifi had been putting him through the harshest training imaginable and he just wanted to sleep. At least a few hours to give him a break from his new life of constant diaper discipline, but it was obviously going to be a long night.
	
His diaper rash was driving him nuts, and the extra small chastity cage locked over his neglected little clit tugged on his swollen, unmilked balls every time he changed positions to escape the itching and burning of his bumpy red rash. He wanted nothing more than to reach down the front of his diaper and adjust his boyhood, but that was impossible, thanks to the straitjacket Miss FIfi had buckled him into before bedtime. Between that and the leather muzzle, he could only roll around in the crib, kick his legs, and suck on the dick-shaped pacifier that was stuck in his mouth.

As if that wasn’t enough, his hairless, shaven ass was still stinging from the lashing he’d gotten from Marzipan earlier, and his tailhole ached from the big studded buttplug that FIfi had stuffed up inside him before taping him into his extra thick nighttime diapers. It was shaped like a nice fat knot to make sure he remembered his place, but it was also hollow, ensuring he’d helplessly soil his pants whenever he had the slightest urge. With the tight crotch straps of the straitjacket holding his thick diaper against his posterior, there was no way it would be coming out before morning, no matter how hard he pushed.

All of these distractions, along with the cacophony of noise reverberating through the walls, would be enough to keep the heavily restrained wolf boy tossing and turning all night. Sleep seemed like it would never come, and the wimpy little diaper slave had been driven to tears of frustration multiple times already. Though, he kept his pathetic mewling as subdued as  possible, knowing that Miss Fifi would likely be listening via the baby monitor, and so much as a peep after lights out could earn him another day of degrading punishments, or even a visit from Marzipan before the night was through.

Eventually, the stress and exhaustion was enough to overcome his other senses, and he began drifting in and out of consciousness. He lost track of time. Dreams and reality began melding together, until he wasn’t sure which sounds were coming from the living room and which were entirely in his imagination. 

Finally, after some imperceivable amount of time, he awoke to find the nursery completely silent. The noises coming through the wall had finally stopped, and just as soon as he started wondering whether he’d dreamt the entire evening up till this point, he heard a voice coming from just outside the door. He closed his eyes and pretended to be asleep as soon as he saw the door begin to creak open, assuming it had to be Fifi stopping by to check on him, but the first voice he heard was Melody’s as she went back and forth with her Aunt Marzipan.

Melody’s voice was barely audible, somewhere between whispering and mumbling as she tried to talk quietly with a pacifier in her mouth. Marcus really had to focus to understand her, and even then it was hard to make out what she was saying, but it sounded like she was asking permission to sleep in the crib tonight.

Marcus was fully onboard with that idea, but he didn’t get his hopes up. As expected, Marzipan denied her request, citing the fact that there was a “pervy little shit machine” sleeping in there already, but Melody remained steadfast. She got a bit louder, almost taking a whining tone with her Aunt as she pleaded her case, saying she never got to try the crib before and she didn’t mind sharing. 

Still, Marzipan wasn’t having it. At least, that’s how it seemed at first, until Melody started in with some uncharacteristic baby talk that seemed to turn the tide in her favor. Marcus didn’t really know Melody all that well yet, but even he was surprised to hear her acting like a big spoiled baby to get what she wanted. Apparently it worked though, because Marzipan actually unlocked the crib and lowered the bars.

“Hey, sissy boy! You awake?” asked Marzipan, raising her voice to normal speaking volume to see if she’d get a response from the motionless wolf boy.

Marcus remained silent, still pretending to be asleep. Though, it wouldn’t be that easy to fool Marzipan, and he received a sharp poke to the belly a second later to see if he was really sleeping. The Clydesdale’s big meaty finger jabbed him so hard that it knocked the wind out of him, and it was all he could do to not curl up in the fetal position and whimper like a big baby.

Fortunately, his straitjacket kept him relatively still, and his pacifier helped muffle the involuntary grunt that escaped his throat as he was suckerpunched. Those brief signs of life actually made his performance more believable, appearing as though he’d been shocked half awake for a moment before immediately falling back asleep in a stupor. At least, it was enough to convince Marzipan he wasn’t a threat.

“I guess it’s okay,” said Marz. “Miss Fifi must have drugged him up before bed to keep him from struggling, but if you catch him snuggling up next to you, just give him a knee between the legs to set him straight and I’ll deal with him in the morning. Got it?”

“Yes, Auntie,” replied Melody. “I’ll make sure he behaves. Thank you! Thank you! Thank you!”

“Yeah yeah, just get your butt in there before I change my mind.”

“Okay… but could I ask for one more tiny little thing?”

“C’mon Melody, you already got your one thing, and it’s past your bedtime.”

“I know, but Auntie… I can’t sleep in these jammies; they’re too warm.”

“Too warm? That’s the point–”

“Yeah I know, but I’ve been boiling in these jammies all night, and I didn’t want to say anything cuz I was watching the movie wif you. Please, Auntie…”

“Fine, but you’d better go right to sleep after this, and don’t come crying to me if you wind up with a cold.”

Marcus could hardly believe his luck as he heard Melody’s pajamas being unzipped. He didn’t dare open his eyes, even for a quick peek, but he was more than happy to recreate the whole scene in his imagination. He shamelessly pictured Melody stepping out of her jammies, vividly recalling the sight of her naked breasts from earlier that day. He felt a shred of guilt as his overeager little boyhood got stiff inside its tiny chastity cage, but he got over it fast. As pathetic as it was, this was probably the closest he’d ever get to sleeping with a topless female who wasn’t his own mother.

The perverted wolf could hardly contain himself as he felt Melody climb up into the crib and lay right next to him. She was so close that he could hear the rustling of her locking plastic underwear as she tried to get comfortable. His heart fluttered as he felt her leg brush against his, but he stayed perfectly still as he waited for her Aunt to leave.

“Nighty night, honey,” said Marzipan, raising the crib bars and locking them in place. “See you in the morning. Sweet dreams, baby girl.”

“Nighty night,” replied Melody, nuzzling her pillow one last time for maximum coziness.

After that, Marcus listened as the big Clydesdale exited the nursery, waiting patiently for his chance to be alone with Melody. He felt an incredible sense of relief as he heard the door click shut. He’d actually tricked Marzipan and gotten away with it. Of course, it wasn’t a massive victory by any stretch of the imagination, but considering how thoroughly domineering she’d been over the last few days, he felt tremendous satisfaction that he’d managed to get one over on her. Now all he had to do was wait for Melody to fall asleep.

He didn’t have any nefarious plans; he just wanted to watch her sleep. Maybe he could even scooch closer to her and fall asleep with his leg pressed against hers to get the experience of sleeping next to a cute diaper girl all night. It’s not like he could go any further than that, even if he wanted to. His arms were useless as long as they remained locked in his straitjacket, and the ever present baby monitor meant that Melody could summon her Aunt at a moment’s notice if she woke up to find a horny little pest humping her leg in the middle of the night. However, it seemed Melody wasn’t in any hurry to get to sleep.

Marcus felt stomach jump into his mouth when Melody pressed her entire body against his. He clamped his lips shut around his pacifier and tried to stay as quiet as possible as the oversized filly wrapped her arms around him and squeezed him tightly into her chest, burying his blushing cheeks deep into her bountiful bosom. He did his best to keep up the charade that he was sleeping, but his heart was pounding so hard he feared he’d wake up everyone in the house. His useless, locked-up dicklette strained against its chastity cage until he had to adjust his hips to try and take some of the pressure off his eager little nub.

Melody didn’t seem to notice, continuing to smother him between her breasts as she curled her legs around his body, treating him like a living body pillow. She wriggled her pelvis, hungrily rubbing her crotch against him in an effort to get herself off through the thick padding of her diaper. Finding little relief from her sexual frustration, she spat out her pacifier and whispered in his ear.

“Are you awake, little boy?” Melody asked, speaking as quietly as possible to avoid being picked up on a baby monitor.

Marcus felt a rush of pleasure throughout his entire body as Melody’s breath tickled the inside of his ear. Maybe it wasn’t overtly sexual, but it was definitely a first for him, and he wasn’t sure how to react. Did she want him to be awake? Was it a trap? Why did her breath reek of booze? He opted to play it safe and stayed silent, but really it had less to do with safety and everything to do with being too intimidated to look her in the eye.

However, Melody didn’t stop there. She reached down between his legs and rubbed the front of his diaper with her mitts, trying to fondle his little dick and balls through the damp padding of his wet Huggies. When that didn’t get a rise out of her new plaything, she took it a step further and began chewing on his ear, refusing to take “no” for an answer.

Finally, Marcus dropped the act and pulled away, afraid that if she bit down any harder, he’d let out a yelp that would wake the neighbors. His eyes popped open and he shot a nasty face at Melody, equal parts surprised and annoyed that she’d pull a stunt like that when any sound could land them both in a heap of trouble. Though, his anger quickly subsided as he caught a glimpse of her lovely figure looming over him, illuminated by the warm glow of the nightlight.

His expression softened, and he put up no resistance as the young mare climbed on top of him. She pinned his shoulders to the mattress with her soft, padded mitts as she straddled him, allowing her naked breasts to hang just inches from his face. He stared up at them in reverence, enjoying the perfect view of her chest. Somehow she looked even more beautiful bathed in the soft light of the nightlight. He wished he could wrap his arms around her and pull her down on top of him, but the straitjacket kept his eager paws bundled up nice and snug, forcing him to lie and wait for her next move.

"Naughty little boy… I knew you were awake,” whispered Melody, grinning playfully as she stared deep into his eyes.

For once, Marcus didn’t look away. He stared back, captivated by her gaze. Was she really serious, or simply toying with him? Did it matter? He’d never gotten this far with a member of the opposite sex before, and he wasn’t sure if he ever would again, so he wasn’t going to fight it. As far as he was concerned, she could do anything he wanted to him and he’d be eternally grateful for it. He would’ve gladly told her as much if it weren’t for the pacifier stuck in his mouth, but Melody certainly wasn’t waiting for his approval.

She began moving her hips again, grinding against him in sheer desperation as he lay beneath her. She exhaled deep lungfuls of hot steamy breath into his face as she rubbed the front of her thick diaper against his, and despite nearly being crushed under her weight, Marcus was smart enough to prop his knee up, giving her his leg so she could thrust into it.
	
She humped at a feverish pace as though she were in estrus, pounding her crotch against his thigh like it was the last stallion on earth. She was red hot with passion and Marcus savored every moment as he bathed in her body heat. Even though his twitching little pecker was caged up, he still relished the feeling of Melody’s nether regions pressed against his leg, and the fact that she was enjoying it so much filled him with a sense of pride that he’d never felt before.
	
After a few more minutes of frantic rubbing, she finally paused to catch her breath. The scent of her wet sex managed to reach Marcus’s sensitive nose and he wondered if she’d actually managed to reach climax. Melody never gave him an answer to that question, but she was nice enough to keep the crotch of her diaper pressed firmly against his leg as she shamelessly pissed herself, allowing her cuddly little plaything to enjoy the warmth of her strongly scented urine as she flooded her padding.
	
“Enjoying yourself?” she asked, leaning in close to whisper in his ear once again.
	
Marcus nodded, staring up at her with a look of adoration.

“Do you want to suck these tits, little boy?” Melody continued.

Again, Marcus nodded with sincerity, wanting nothing more than a chance at her perky nipples. Unfortunately, the only thing he’d be sucking tonight would be the cock-shaped pacifier that filled his mouth, or so he thought.

Melody moved in even closer, like she was going to plant a kiss on his wet nose. Marcus closed his eyes and waited for his first kiss, but it didn’t come. Instead, Melody grabbed his pacifier with her teeth and started tugging. The leather muzzle strapped around his head kept his maw clamped shut around the base of the rubber phallus, but with enough effort, Melody was able to free it from the wolf’s mouth, allowing his lips to be used for her own pleasure.

She flung his pacifier out of the way and laid down next to her eager plaything. She rolled onto her side to face him and pulled him in close, squeezing him tight like one of her plushies. With one of her mitts on the back of his head, she guided his mouth toward her nipple and waited for the timid little virgin to latch on.

Without needing to be told what to do, Marcus took her firm, meaty nipple between his pursed lips and started suckling like a big baby. He started out nice and easy, lubricating the fleshy nub with his saliva before sucking it deeper, careful not to let his jagged incisors get in the way. In just a few seconds, her nipple was fully engorged, swollen and bumpy as he tickled it with the tip of his warm, slippery tongue. He listened intently, taking his cues from the sound of her breathing to know when he was on the right track, speeding up until he heard her gasping for air, and then slowing down before it became too much.

“Ungh… good boy,” Melody whispered through clenched teeth as she reached down with her free hand and pawed at the front of her diaper ineffectually with her mitt, desperate to stimulate her excited little clit through the layers of thick padding.

Marcus considered that high praise, coming from the mouth of a goddess like Melody, and he wanted nothing more than to help her achieve orgasm. He switched breasts the moment he felt her begin to cool down, allowing the first nipple a chance to regain its sensitivity as he started anew with the other, repeating the process of getting it wet and slick before sucking it past his lips and rolling it around with his tongue. Just as he’d hoped, he could feel her breathing becoming ragged and shallow again as he worked the fresh nipple between his lips, bringing her closer to the edge as she enthusiastically groped her damp, twitching pussy through her diaper.

“Keep going… Please don’t stop,” continued Melody, muttering encouragement under her breath as she arched her back. “Oh god… Don’t fucking stop…”

Marcus didn’t need to be told twice. He was fully invested in getting her there. Hungry to prove himself, he darted his tongue out, lapping all around her sensitive nipples and areola. Once they were soaked with spit, he blew on them, tickling them with a sharp stream of cool air that sent a chill up her spine before resuming his sucking and slurping. He continued switching between nipples, doing his best to focus on whichever one seemed the most responsive at any given time. He savored every little moan and vocalization he managed to draw out of her, reveling in her pleasure as if it were his own, becoming more concerned with making her shudder than keeping her quiet.

The closer Melody got, the noisier she became. At first, Marcus had to gauge his success based on the intensity of her breathing, then he started to hear an occasional groan or murmur. Soon, he had her whimpering each time he flicked one of her nipples with his tongue. He was mindful of the volume, knowing they were playing with fire, but he was already in for a whole pound at this point. Surely, he would face retribution when Miss Fifi found him in Melody’s arms the next morning with his pacifier on the other side of the crib. So he figured he may as well try to make his lovely playmate cum before anybody had a chance to stop him. Then he’d have at least one positive sexual experience to remember as he lived out the rest of his life as a dickless sissy diaper sniffer.

Luckily, despite all of the buildup, Melody didn’t make a sound when she finally climaxed. She opened her mouth like she was going to, but nothing came out. She remained silent as she continued to rub the front of her diaper in a fit of excited delirium, trying to extract every last second of pleasure before she was fully spent. Every muscle in her body tensed up, and she squeezed Marcus so tight that it forced the air from his lungs. He wasn’t about to complain though. This was exactly what he wanted. He got to watch, and feel, Melody cumming her brains out, and it was he who helped get her there.

“Okay, enough… No more,” she muttered, barely audible over the heavy panting breaths that escaped her chest.

The wolf boy’s chastity cage had never felt tighter, but it was a small price to pay for a chance to slobber all over Melody’s chest. He went to lay his head on her shoulder, but she pushed him away. Marcus was disappointed, but not totally surprised. Even still, he considered that night to be a massive victory, and probably the best he’d ever have. He rolled onto his back and closed his eyes, doing his best to think about anything else until his erection went away, but that was easier said than done. Especially when he found himself wrapped up in Melody’s arms once again.

This time she’d taken the position of the big spoon, forcing him to be her little spoon all night. His arm was in sort of an uncomfortable position, and her leg felt like it was crushing him after a while. On top of that, she continuously exhaled hot, humid air into his face that smelled like pure alcohol with a hint of cinnamon, but he wasn’t going to let any of that bother him. He was content to be her stuffie for as long as she’d let him, even if it meant he didn’t get any sleep at all that night.

** 21 **

Miss Fifi’s office chair creaked under the weight of the plump basset hound as she leaned forward to grab a wet wipe, needing something to remove the scent of wet dog pussy from her paws. She knew Melody and Marcus were up to something in the crib last night, and her first act of business in the morning was to check the nanny cam to find out just how much trouble those two were going to be in after breakfast. Naturally, her investigation revealed pretty much what she’d expected. Though, she hadn’t expected to start soaking through her panties halfway through.
	
She’d heard a whimper or two come through the baby monitor last night while she and Marz were getting ready for playtime. Marz wanted to go check on them right at that moment, but the clever hound was able to pacify her partner by insisting that Melody was probably just talking in her sleep, and pointing out that the baby monitor went silent immediately after. Of course, Fifi had a feeling her little diaper slut Melody was probably in there humping anything she could get her mitts on, and a review of the baby cam footage the next morning confirmed she was at least half right.
	
She wasn’t surprised to see the perpetually horny college girl climbing all over the straitjacketed wolf, but the part where she made him suck her tits was downright brazen, considering both she and Marz were on the other side of the baby monitor all night. To their credit, the frollicking diaper slaves nearly avoided detection, if not for Melody’s coquettish little whimpers during the height of her ecstasy. Despite being annoyed that her promiscuous pony plaything would pull a stunt like that after all her training, Fifi had to admit she was kind of impressed with the girl’s sex drive. Enough so that the hound couldn’t resist hiking up her dress, stuffing a fat, greedy paw down the front of her panties, and aggressively stroking herself off in the middle of her office.

After she’d satisfied herself and cleaned up her sticky paws, she continued to scrub through the footage from last night to see if Melody got into any other shenanigans that needed a harsh correction. However, it looked like the two of them slept through the rest of the night without incident, and Fifi was just about to go let her naughty babies out of the crib when she glanced at the live feed from the baby cam and noticed Melody was already awake. 

Miss Fifi plopped her big round butt back down in front of her computer and zoomed in on the crib to see what that little reprobate was up to now. Much to her amusement, she saw Melody caressing Marcus’s padded ass with her mitt-covered hands. Turning up the sensitivity on the baby monitor, she could hear every creak of the mattress along with a ton of irritating white noise. Thankfully, it didn’t take long to catch Melody whispering in the wolf boy’s ear.

Fifi couldn’t stop grinning as she spied on Melody’s perverted escapades. Just a day ago, the bashful filly could barely bring herself to utter the word “diaper” out loud, and now she was mashing a diaperful of warm shit all over her new plaything’s messy backside while scolding him for stinking up the crib. The voyeuristic hound snickered, enjoying the fact that the sissy wolf boy was being teased for loading his Huggies during the night even though the hollow butt plug stuffed up his tailhole made it impossible for him to control his bowels. So not only did bitch boy have to suffer the indignity of soiling himself in front of a girl he liked, he also had to take the blame for something that wasn’t even his fault. That was nearly enough to get Fifi’s motor running again on its own, but things only escalated from there.

The curious hound watched as Melody climbed on top of the helpless wolf and shoved the seat of her wet diaper right in his face while ordering him to spread his legs. Unsurprisingly, the docile little mommy’s boy did what he was told without hesitation, and was rewarded handsomely as Melody massaged the front of his swollen diaper with her padded mitts, seemingly trying to coat every last inch of his diaper area with filth.

Fifi couldn’t help but notice all the extra work Melody was making for her, and she was already trying to think of an appropriate punishment for the disrespectful brat. However, Marcus seemed to be enjoying himself, bobbing his knees up and down as Melody played a perverted game of pattycake with the front of his Pampers, completely unaware of what was coming next.

Melody leaned forward and lifted her tail, keeping her diaper planted on the oblivious pup’s face as she pushed out a heavy payload of manure into her pants, assaulting Marcus’s unsuspecting nostrils with the fetid stench of her shit before he could pull his nose away. He immediately began to try and squirm out from underneath her heavy diaper, but his straitjacket rendered him totally helpless as Melody pinned him down and forced him to sniff the bulge in the seat of her Huggies.

“What’s the matter? I had to smell your muddy diaper all morning. It’s only fair that you have to smell mine,” said Melody with a smirk, her voice coming through perfectly clear on the baby monitor now that she wasn’t even bothering to whisper.

Fifi watched on as Marcus weakly kicked his legs, trying to make it look like he was putting up a fight, but it was obviously all for show. He didn’t really want to get away from Melody. The incorrigible little sissy was probably rock hard in his chastity cage as he bathed in her stink, and he was just too ashamed to admit it. Not that it mattered, Melody was going to keep bullying him either way.

“Oh, so you can dish it out, but you can’t take it?” she asked, forcing him to nuzzle her lumpy, well-used diaper. “If you want me to keep playing nice, you’d better give it a big sloppy kiss.”

Fifi smiled wide as she watched her once so innocent filly tormenting the wimpy wolf boy like a pro. The girl definitely had a knack for making a diaper perv like Marcus squirm, and the hound’s eyes stayed riveted to the screen as she waited to see what would happen next. Unfortunately, she didn’t have a great view of Marcus from this angle, but the little sissy bitch obviously didn’t follow orders quickly enough for Melody’s liking.

He let out a weak yelp as the pushy young mare smacked the front of his diaper to get his attention, giving him all the motivation he needed as the exaggerated sounds of Marcus frantically smooching Melody’s rear end were picked up on the baby monitor a moment later.

“That’s a good boy,” continued Melody, rubbing her filthy padded ass all over the boy’s face. “Now keep going. Keep kissing my mushy butt until I tell you to stop.”

Marcus obliged, planting a seemingly never ending barrage of smooches on Melody’s rump as she went back to kneading the front of his squishy Pampers as best she could with her dainty little mitts, but that didn’t stop her from teasing him incessantly as she worked.

“Do you enjoy having your sorry little unmilked balls buried in slippery baby shit?” asked Melody, her tone becoming more serious as she squeezed and smooshed his filthy diaper-clad genitals through his diaper. “Answer me, boy… Don’t make me crush your worthless little grapes.”

The kissing sounds came to a halt as Marcus timidly attempted a response before being cut off prematurely, “Y-yes, Melod–”
	
“Excuse me?” she asked, feigning disbelief as she stopped the wolf boy short with another quick smack between the legs. “You’ll address me as ‘Miss Melody’, got it?”
	
“Yes, Miss Melody!” cried Marcus, likely too afraid of receiving another blow to his already aching, pent-up testicles to stifle the volume of his voice, forgetting all the harsh training Fifi and Marz had put him through in favor of pleasing his new diaper queen, Melody. Little did he know, his domineering nightmare nanny was nearly in hysterics in the other room as she watched over them from the privacy of her office.
	
“That’s a good bitch,” said Melody, refocusing her attention on the boy’s excited little locked-up nub. “Now I want you to push your dumb fuckboy nose deep up into my padding so I can feel it tickling my tailhole, understand?”

“Y-yes, Miss Melody,” answered Marcus, a little less overzealous this time, but still loud enough to be heard clearly over the din of crinkling diapers.

Melody sneered as she felt his muzzle poking her between the asscheeks, bossing her new favorite plaything around as she continued to mash the sissy boy’s soft stool into his short, stubby cock cage.

“That’s right! Now keep it there,” ordered Melody. “Savor the aroma, you nasty little poop sniffer.”

“Yes, Miss Melody…” said Marcus, his voice wavering slightly as he felt his balls begin to twitch from the pleasure. His neglected little dicklette hadn’t felt anything other than discomfort since being locked away in chastity, so even just the feeling of his own warm mud squishing around the head of his cock was incredibly stimulating.

Suddenly, he felt his muscles spasm. His legs stretched out in front of him, straight and rigid, as thick, creamy cum oozed from the end of his cramped little sissy clit and pooled around his quivering shit-covered nutsack. He let out an embarrassingly high pitched whimper as he was rocked by the most powerful orgasm of his life. His toes splayed out and his tail curled up between his legs as he waited for the backed up semen to exit his balls. Then, after only a few seconds of complete ecstasy, his body went limp, melting into a puddle under Melody’s weight.

The befuddled young mare didn’t say anything for a moment, wondering if the sissy wolf boy really just did what she was thinking he’d done. Then she let out a laugh that reminded Marcus was a complete joke he’d become.

“Oh my god… Did you seriously spooge your Pampers from that?” she asked, still laughing as she climbed off of him in disgust. “Admit it! You came from fucking the inside of your shitty diaper, didn’t you?”

“Y-yes… Miss Melody,” answered Marcus, on the brink of falling asleep, totally drained from the whole experience.

“Wow, that’s pretty gross. Pretty hilarious, but also pretty gross,” said Melody, ruthlessly teasing the exhausted sissy as he lay helpless in his straightjacket and soiled diaper. “Well, what are you waiting for? Thank me, you little ingrate!”

“Thank you, Miss Melody,” replied Marcus, resting peacefully, seemingly unconcerned with the degrading manner in which he’d gotten off. He thought he’d never cum again, so he’d happily take what he could get at this point in his life.

“Miss Fifi was right, you really are a pathetic excuse for a boy, you know that?” asked Melody, not giving the contented pup a chance to relax as she switched positions, plopping her sizable breasts down on his dopey face, expecting a repeat of the previous night. “Now thank me properly, before I rip that diaper off your waist and shove your nose in it.”

Meanwhile, Fifi’s already sizable ego inflated like a balloon as she overheard Melody emulating her like that. It was truly a testament to her skills as a domme that she’d turned the shy college girl into a full-blown diaper slut in such a short amount of time, and there was still plenty of time left to explore all manner of sick, twisted fun with her new protégé. The depraved hound stuck her paw back down into her already soaked panties as she thought about how she’d be torturing and tormenting Melody for the remainder of the day as punishment for her morning mischief, and Marcus too. Though, first she was going to sit in her office and enjoy the rest of the show for however long it lasted, or at least until she was fully satisfied.
