Under the Influence
By Onyx Cheetah

Wrapping his arms around the slender cheetah's shoulders, the large purple dinosaur- Barney the Dinosaur to be specific- growled seductively, almost inaudibly, into the dark-yellow furred ear. The feline squirmed in his seat on the public park bench, a soft rustling coming from under the girlish clothing he was told to wear.
Barney nibbled on the cheetah's ear and reminded him that today the cat was going to prove his love for the big dino. That he was going to do anything that he was told to do. No matter how dirty, or wrong, it may be. He would "protect” him, of course, Barney always had some strange kind of magic that always went over the cheetah's head, but fascinated him. Even so, the thought of having to do everything Barney told him to do  turned the cheetah on, yet frightened him. Making the cheetah do everything asked of him even if it was totally against the way the cheetah's mind supposedly thought. 
It ultimately didn't really matter what the cheetah thought anyway; Barney could use his "imagination” magic to change the cat's mind subtly to do his bidding- especially with the cat head over heels for the incredibly naughty dinosaur. Touching the cheetah's cheek with his plush paw, Barney moved the cat's head to face his own. "Aww, my little Onyx, you have no clue why we're here, huh?”
The cat shook his head blushing at the dino's surprisingly lusty gaze, reminding Onyx of the look Barney gave the night the cat admitted his love of the plush dinosaur and the resulting hours upon hours of sweaty, rough, hard and mind blowing love making. Absent-mindedly, the cat began to bulge under his pants and into the diaper hidden under them. Getting hard right there- in public.
Barney growled again and groped at the small bulge not even showing more than a tiny bump through the upper layer of the cat's clothing. Embarrassed, the cheetah squirmed again. They were in a public park after all, around children and their parents, but Barney held a firm grip and chuckled."This. This is why we're here. Your little baby dick is so ready to play, but you're so afraid of everyone else around you. Well, I got to cure that.” He gripped the trapped member tighter. "So, you're going to end up satisfying a little one.” 
Barney moaned in ecstasy to himself while the cheetah went wide eyed in disbelief. The plush dinosaur’s words slowly dawned on him, probing deep into the poor, unsuspecting cheetah's mind. "That's right.” His grip started to massage and tease the poor cat. "This is going to fill a cute cub. And no matter what you are thinking now, you're gonna love it.” 
Barney stared into his eyes smiling warmly as he said this, causing the cheetah to squirm as he continued to be taken back by his words. Barney held firm though, holding the squirming cheetah to him despite the shock and pushback from the kitty. Unbeknownst to the cheetah, Barney's magic was beginning, just barely using it to subtly get the idea in the cat's mind that he might subconsciously want to actually fill a young cub. His squirming turned slowly into an embarrassed blush the more he stared into the attractive plush dino's eyes, eventually hiding his face into the plush chest. Occasionally, the large dinosaur forced the feline to turn his head out towards the various areas of the park as he whispered in the cheetah’s ear about how adorable certain cubs looked and what he thought about each one- adding some profane words and ideas to each one he liked.
Conflict fought inside the cheetah's mind, but the magic continued to fight off any thoughts of this entire venture being bad. His own cock didn't help, remaining rock hard at each and every thing Barney mentioned doing. And at least a few times twitching as Barney told him to look at one of the cubs passing by. Every time Barney whispered into the feline’s ear, his heart would race and the predicament seemed more natural and he'd want to do it more and more.
The longer the cheetah hid in the plush green chest the stronger a certain familiar, attractive scent became. Looking all around, he found the scent as he looked down towards the plush dinosaur's crotch. The purple tip of Barney's member was pushing up out of the slit in his crotch, pre already forming on the tip and dripping slowly down the length that had freed itself from its home. Unashamed, Barney ran a paw over the thick girth and moaned deeply, staring off at something or someone out in the distance of the playground.
Turning to where the dinosaur was staring, Onyx spotted a little mouse girl no older than 5, running around a basketball court all alone while bouncing a playful rubber ball. Onyx looked back up at Barney, but his gaze continued to stare lustfully at the cub girl.
"Oh my! I think we found a new playmate to come and play with my little sissy cub girl.” His throaty-nasal voice seemed to echo through the cheetah's entire mind, causing him to once again hide his face back into the plush chest.
Barney's scent now seemed to flow from his entire being, driving the cat wild. Thoughts of being so naughty gripped every bit of his mind; his cock unrelenting against its diaper prison, threatening to break though at any moment. Barney's magic had done its deed. It made the kitty a slave for what he wanted to happen.
Barney, knowing that the poor kitty was under his special "guidance” let out one of his patented "Dawws!” and a grope to the diapered rear, both of which caused the kitty to press his face into the plush chest harder.
Letting out another "Daww,” this time more guttural and deep, straight into the cheetah's ear- more along the lines of a needy growl rather than finding something cute or adorable like he would normally do- Barney moaned. Onyx looked towards the little girl. She must have lost control over her ball as she chased after the ball rolling away toward the two of them. The cat once again went wide eyed as he realized why Barney was giving off almost primal growls as she grew closer. He tried to hide his face again but Barney forced him to look at his newest fixation as she unknowingly came up to the naughty dinosaur and embarrassed kitty.
As the ball came up to the two of them, Barney stopped it with his foot, having the young mouse come right up to him and bend over in front of him- oblivious to the large dripping dino member twitching right in front of her face. Onyx looked up at Barney and he smiled pointing at his dripping cock. As Onyx looked back it disappeared and reappeared. He was using his magic to shield himself from public view!
"Hehe, such a sweet little mouse!” he smiled down at her, holding the ball under his footpaw keeping her around as he examined her. Barely audible he whispered deeply into the cheetah's ear as if he was reaching into his very bones, reverberating the feeling throughout the mesmerized cheetah using more of his magic. “Such an innocent and sexy one too.”
The cheetah's face went redder than ever, reaching up to his very ears.
"Now Onyx, go on and help out our sweet little new friend here with getting her ball.” The incredibly embarrassed cheetah looked up at Barney confused, the ball was right there why did he have to get it? What was the dinosaur going to do?
Standing up with a blush and a lightheadedness from the magic and the constant blood flow to his crotch, the cheetah grabbed the ball and climbed over the purple footpaw intending to head towards the mouse. Instead though, as the cat stepped over Barney lifted his foot causing the poor confused cheetah to trip and roll onto the ground, his loose pants sliding down just enough to expose a bit of his pink diaper to the world. Smartly, Barney blocked the view for anyone but those close to the cat.
She gasped, running over quickly to help the dazed cheetah as she was taught to do in her pre-school class if she saw anyone get hurt. She couldn't really do anything to help but she still wanted to help if she could. It wasn't until she got right up to him that Barney let her vision through his blocked magic, letting her see the exposed diaper without question of what it was. The tapes, the design, the crinkly pink plastic- it was a nice thick diaper. The little mouse stared. He was unable to do little more than sit there, exposed and embarrassed.
"Is that…?! Mommy lied! They do make them bigger!”
The cat squirmed as he sat there, the little one overly examining him, super excited; her mind seemingly going through everything her parents told her that could be wrong. Her tail lifted up, wagging as she thought of all the possibilities.
Barney stood up walking over to the pair, standing right over top of the kitty and dripping onto him. “Oh, do you like diapers, little mousey?” Barney sweetly smiled at her, his cock twitching against Onyx, causing such an innocent question to become a naughty, dirty one.
She nodded her head, and her body shook excitedly. "Uh huh! Momma says I have to leave them soon, but I love them, I dun wanna!”
Barney let out an almost inaudible moan yet again and rubbed his cock, still hidden by his imagination magic. "Almost too good to be true. I knew you were a special little mouse wanting to stay a cute little toddler girl forever, just like my little toddler girl here!” He grabbed hold of the shocked and embarrassed cat under his armpits, and lifted him onto his feet, standing there with the top of his diaper still exposed to the little mouse. "I bet you'd love to see how they fully look!”
The cheetah’s eyes went wide as he realized what was actually happening: the dirty dinosaur was going to make Onyx expose himself or worse to the young cub! But for some reason, he couldn’t fight it. Part of his brain was yelling at him to stop it, begging him to just leave, but the other part was needing to show off to the young girl. By the time his brain had stopped arguing, his body had already made a choice- he was already on his way following the purple dinosaur and the sweet, excited young mouse girl towards a public bathroom on the far off side of the park.
Stepping into the dimly lit bathroom, Barney locked the door behind the three of them, giving special attention to make sure to shroud themselves from everyone with his magic before walking in. Turning, he smiled at the two “cubs” standing there in front of him, one trying to hide himself in embarrassment and the other bouncing innocently and happily.
Staring at the cheetah, who only seemed to crunch up into himself the longer he stood there, the plush dino gave a smirk and soft growl. “Pants off, lil girl.”
Onyx squirmed and whimpered, turning bright red, but slowly started to unbutton and pull down his pants exposing a lightly wet pink diaper fully to the 4 or 5 year old mouse girl. Her eyes went wide and she giddily clapped her paws together and ran up close to the cat, placing her little paws on the diaper to feel the plastic. The cheetah instantly stood up straight, his muscles stiffening and unmoving, barely letting out a breath. The only movement came from inside the diaper, his little feline member stiffening itself to an unhidable tent, throbbing hard as all of Barney’s mental influence came to a head as the tiny paw explored the plastic of the diaper… including the outline of his tent.
“How about you show off yours, hun?!” Barney played up his playful voice as he smiled at the mouse. “I think it’s only fair! And I also bet that my little cubby girl would love to see your cute little diaper, and maybe ask Daddy Barney for similar ones in the future!”
She pulled her paw off the front of the tent and nodded to the purple dino innocently. She stepped back and pulled down her skirt, allowing full view of her very childish, thick, pink diaper sitting snugly on her waist. A very light urine scent filled the air as her diaper waistband became free from the skirt that had been constricting it to herself. Hidden within the urine smell was a young musky scent. Not a harsh scent, but one the cheetah recognized from his own youth, reminding the cat just how young she was. Onyx stared at the newly revealed diaper- it was all he could do as every manipulated dirty thought entered through his mind and flowed down into his crotch, ending with a twitch inside his diaper.
Barney walked over to the panting feline wrapping an arm around him and whispering into his ear, the lust in his voice fully on display. “Isn’t she the cutest little 4 year old? Diaper lover and wet, just like my little girl. Just like you. She was made for you.” His dripping member pressed into the cheetah’s spotted side as he excitedly talked about his capture. “She is so excited to learn she can be a cub forever, and I bet you can show her what older cubs love to do.” He let out a long, needy sigh in the cat’s ear and stared at the little mouse. Reaching his paw down to the cheetah’s tented diaper front, squeezing it and rubbing it softly, the dino moaned.
The cheetah’s eyes rolled back into his head as Barney’s magic continued to wreak havoc on the poor subby feline mind; the coercion ran through his entire being. His cock twitched with the rubs and leaked an overabundance of pre into his diaper. Onyx squirmed and let out a deep and needy sigh.
“Mmmm. That’s right. Look at her diaper.” Barney continued as he rubbed the cheetah’s privates, “I bet it would feel so good, just like yours does.” The dino squeezed the twitching member hard, “I bet it would smell even better! Why don’t you ask her if she needs a change? Give her diaper a little feel like she did yours, give her a diaper check!”
Everything screaming “No!” inside his mind was drowned out as his love, his obsession, pressured and coerced him. Barney’s magic pressed hard into his mind, pulling the dirtiest thoughts hiding in the depths of his mind to come out to the forefront. Without thinking about it, the cheetah walked up to her and gave the front of her diaper a touch like she innocently gave him. Electricity felt like it flowed through him, his diaper twitching hard with a crinkle. In turn, she responded with a playful giggle and spread her legs a little, giving him access to lay his full paw against the mouse’s crotch. Beet red up to his ears, the cheetah gave the diaper a slow, soft rub.
“L-looks… looks like uhh… well… your d-diaper.” The cat stammered and the little mouse looked at him curiously. “Your diaper is wet!” The cat blurted out loudly unintentionally, unable to collect his thoughts in a smart manner from all the mental manipulation. He looked down, paw still on her diaper, and collected himself with a deep breath. “Your diaper is w-wet… would you like a c-change?” The cheetah throbbed in his diaper as he got through the innocent question.
“No!” The mouse called out loudly, enough to worry Barney for a second before remembering his magic meant no one would know they were around. The call made Onyx pull back in shock, his paw dropping from her crotch, pushing his mental state partially back to reality. He kneeled there in a stunned position, his mind twisting over itself with his own dark coerced thoughts and his own free thoughts colliding for just that moment. “I like being wet!” She giggled and wiggled her diapered bottom, causing the wet garment to squish and wiggle around in the feline’s view. The sight of her cubby diaper moving around on her pushed his thoughts back into his naughty state.
Barney kneeled down and smiled at her, “Daww! Just like my little cub! I think you two will be great friends!” Picking up the cub, he opened up the changing table in the room and sat her upon it on the edge of the table, letting her little legs swing off the side. “I think my cub is just jealous of your pretty diaper! But if she gets a close enough look for a bit, she can know what to buy next time we buy her diapers! Can she have a better look at it?”
	The plush paw patted against her head and she smiled with an “mmhmm” and spread her legs wide, showing off the wet diaper’s thickness on the edge of the table. Barney walked over to the cat and pulled him over to her before pushing him onto the floor, his vision greeted with the 4 year old’s wet diapered crotch staring back at him. The kitten let out a whine and a soft moan. The dino’s paw pushed on his head and slowly “helped” the kitty get closer and closer to the diaper sitting right before his muzzle until it lay against it. The cheetah couldn’t help but inhale her immature scent- not that he wanted to stop. His everything wanted to breathe in that scent. As Barney held his muzzle in place tight to the mouse cub’s diaper, making it impossible to pull away, the cheetah’s diaper gave one last premature twitch before his entire body stiffened. Starting just from his crotch, he began to violently twitch all over, his first orgasm pushing any doubt of loving this away from his mind, maybe for good, as each pump of feline seed exploded into the cheetah’s diaper front. Barney smiled a mischievous smirk and held the cat in place until the violent orgasm finally subsided.
	Barney moved his paw from the cat’s head but the kitten didn’t follow back, continuing to inhale the cub’s wet diaper scent of his own free will. Barney’s cock throbbed as he smiled watching the scene in front of him, knowing that his will was now his kitten cub’s will. He murred and his sweet and nasally voice lowered, “I wanna see how your diapers look like together, front to front!” He smiled big at the two, Onyx blushing as he looked up to face him as he slowly registered the naughty suggestion his big dino gave. The little mouse nodded happily, ignorant to anything naughty going on.
	Onyx stood up on shaky legs, using the changing table to balance looking back over the tiny girl. She seemed different to him now after he had exploded in his diaper to her. More… sensual. Her little movements and spread legs made things inside his brain light up, his diaper re-tenting already. Gripping her legs he gently slid her closer to him, her diaper ending up barely over the edge of the table as he stopped pulling her. Feeling his heart continue to pound in his chest, he slid close to her, settling his tented diaper against hers.
	Clapping, the mouse girl giggled. “They look the same!” She beamed, so happy that she could one day have similar diapers as the ones she currently wore and loved.
	Moaning, Barney smiled. “Uh huh! And they’re both very pretty! I know my little girl thinks yours is pretty. Do you think hers are pretty too?” The mouse girl nodded. Barney growled lustfully under his breath, everything was sliding perfectly into place. He knew the next step was going to be make or break- for all of them. He put on his giddy attitude, one that was comforting for the little girl to help push her towards a positive answer. “Wanna know how bigger cubs show their friend’s that they are pretty?”
	As Barney’s question echoed in his mind, Onyx felt as if he started to wake from a dream, the mental influence dropping from his mind, leaving him alone inside his own head. He stared at the scene in front of him, shocked. He shook his head, trying to piece together his feelings and thoughts of everything that had happened, looking over at Barney who just smiled back.
	“I know you want to.” The two cubs took Barney’s statement in different ways, the mouse nodding to answer Barney’s question while the cheetah huffed as he knew what he had already done, and that he loved it. He knew Barney helped him forward through it, but it was all him. He wanted to sniff that crotch, he wanted to be diaper to diaper with the cub, and he was still tenting his diaper as they remained together. But he was still too hesitant, too nervous to answer. Barney smiled as he saw the realization in his eyes and knew his cub would go further. He just needed a little bit more of a push, sliding the cheetah back into his influenced mental state.
	The cub smiled and looked at her two new, much older, friends. “I wanna know! I wanna be a big cub like her when I grow up! Teach me!” 
	Barney growled and moaned, his dick twitching and throbbing as he knew he convinced the young mouse down the path away from innocence. He slid close to the two, pulling the cheetah back slightly giving him a view of the cub’s crotch. Grabbing the leg gathers of the wet diaper he pulled, stretching them slowly so as to not rip, but far enough to leave her wet, immature cunny exposed. The cheetah huffed but tried to look off to the side, away from his treat. Gently Barney moved his head back, forcing him to look at the cub’s most intimate, private bits.
	As the cheetah stared at the first cub vagina he’d ever seen, Barney grabbed hold of Onyx’s own leg gathers, doing the same thing as he had done to the little girl’s. The feline’s 3 inch member lost no time in bouncing out, freeing it from the tight jail of the diaper. It dripped onto the floor as it throbbed, his cum covered cock already needing new release as it dripped fresh pre. “There’s a good girl, my little cub lover.” He growled lustfully in the cheetah’s ear, “Just like me!” Grabbing hold of the small member, he pulled him forward slowly, agonizingly slow, towards the 4 year old’s tight little slit.
	He laid the cheetah’s tip against the pussy and gave off another “Daww!” as he looked at the scene, clearly enjoying himself. But he pulled his paw away, letting the member just sit there against the hole. “That’s as far as I’ll help you. I know you want it.” He moaned softly but his voice became serious. “Now, are you my dirty little cub, or do we end here?”
	The cheetah’s mind cleared of the coercion, becoming clear again, but his lust remained. What had been in his most naughty fantasies was right in front of him. Dick against the young mouse, a little toddler. Onyx looked toward his purple dinosaur and his throbbing dino member, dripping as he stared at the diapered pair. The cat groaned as he shot pre onto the tight slit.
Onyx stared at the little mouse on the table below him, swallowing slowly as he slowly pushed his small cheetah dick into the tight hole that lay open for him, wet with pee. A whimper erupted from the tiny maw of the cub as the foreign invader plunged into her orifice. 
Though way smaller than that of the dinosaur giddily watching from the side, the cheetah's dick was still much larger than any finger that may have slid against or in during a diaper change. She shut her eyes, tears slowly forming, not from sadness or any real pain, just some soreness from her being slowly stretched out. She fought to hold back any whining or crying out. She wanted to be a big girl in diapers, like the kitty in front of her pushing into her. Like the nice, fun dino said.
The cheetah came across a barrier as he gently pushed into her. He felt her squirm more and stopped, looking down at her teary eyes. Almost pulling out there, Barney held him in place. "Dun worry, it's just her cherry. She's a good little virgin. It'll hurt her for a second, but she'll love it after."
Still unsure, Onyx closed his eyes and breathed in deeply before looking back at her. She opened her eyes back up as he hadn't moved inside her in a bit and stared back at him. "Do you want me to stop?" 
She quickly shook her head. "I'm a big girl, I can wear diapers and be a big girl. I wanna play good big girl games!"
Barney smiled at him, settling back behind the cat to rub his shoulders, encouraging the cheetah to keep going, his dino dick rock hard as the cheetah pushed harder until her virginity was taken forever, her insides unable to hold him back even if she had wanted to. She tensed and let out a long sustained cry as the pain enveloped her immature body, the cheetah softly petting her until the pain dulled. As he pushed into the tightest, warmest orifice he had ever been in, he felt a warm slickness suddenly land on his lower back, right over his rear. Looking back, he saw that Barney had exploded all over his backside as he took her innocence. The cheetah blushed, but his lust grew more and more as he knew his dinosaur was proud of him.
As her body finally relaxed the toddler mouse looked up to the two in tearful eyes, sniffling. "A-am I a big girl?"
Barney smiled and grabbed her paw, holding it gently before placing it in Onyx's. "Yes you are, you two are very good big girls!" 
Onyx knew that he meant that as praise for him going through with taking the cub's virginity, as well as for the young mouse's comfort. He could plainly see it in the way the dino meat throbbed as he watched. Though it wasn't as if he was only doing it for Barney, his kitty dick was the hardest it'd been since he played with Barney for the first time. He loved being inside the tiny mouse, it felt so good just to let his feral needs take over and to make the little mouse cub his. He began rocking his crotch, pulling his kitty dick slowly out then back in, letting himself push in deeper each time. 
The little mouse gasped and squirmed, thinking that just that pop and pain was the end. Instead her loins filled with strange sensations she'd never known before. The pain still existed, but it devolved into just a small flame surrounded by the new feelings. As he pushed deeper and deeper with each hump she felt a feeling of being full- but it was as foreign as familiar, feeling it come from a different place. She also felt as if she was shocked by static electricity, but not in a bad way. Like the tingling of it without the pain of it, and it kind of tickled her insides. It made her feel good. An unmistakable moan escaped her cubby lips, igniting the lustful need filling the cheetah's eyes.
Letting off a small growl, Onyx finally pushed his entire member fully into the little hole, hilting the mouse cub. As he felt their two crotches connect the cheetah moaned loudly, a bit of pre shooting from his tip. He was fully inside the mouse, inside a 4 year old cub- and he loved it. 
Barney let out a fresh "Daww!" as he watched from the side as his kitten took the cub fully, loving the sight as he rubbed his thick dino dick again, still soaked in his cum. The cheetah looked over at the purple rex, staring deep into his eyes. "There you go, there's my little cub fucker! Fully inside a little one and I bet someone's close to cumming, huh?!" He sounded so happy and giddy that Onyx was inside, causing the kitten's pleasure centers in his brain to go wild as if it was everything he lived for. The kitten could only nod enthusiastically, panting as he began to pump into the girl.
The mouse was also panting, the new intense feelings causing her mind to overload. The only thing she could do was feel- and she felt so good, so amazing. It was so much, almost too much. She felt as if a dam inside her was about to break, that she would pee. She tried saying something, but the only thing that came out of her tiny muzzle was more squeaks and moans. She tried holding the feeling back, but every push inside by her new big girl friend drew it closer and closer to breaking until finally she felt it, and she squealed.
Onyx first felt the vice-like grip upon his dick before her squeal, her tiny pussy beginning to quiver around him as she had her first orgasm ever. He couldn't hold back after that. The only thing he could do was push himself in hard as she squirmed and squealed, himself moaning loud as he began to cum into her tiny body.
Excited about the scene in front of him Barney clapped his hands. "Oh boy! This is a fantastic sight to see! Good girls!" He looked toward his little kitten's face as he came into the girl. Grabbing Onyx by the back of his head he pulled him toward him, forcing him down eye level to his throbbing, dripping cock. Pushing his tip to the cheetah's lip, he smiled. "Open, baby girl!"
As the cheetah opened his maw, the dino slipped in quickly, the cat could taste the last load he had exploded all over his back. He blushed and lapped it up, still throbbing and cumming inside the mouse girl. Barney moaned and held him there making him suck on the thick, throbbing dick. He pushed his paw hard, holding him in place, thrusting a few times into him before exploding again down the new cub fucker's throat.
The cheetah pulled back at the sudden gush of dino cum entered his throat, but Barney held him firmly in place as he let load after load into him. What came earlier all over the kitten's backside was nothing compared to what he was letting out now. Barney finally felt full relief as his own mate was now a certifiable cub fucker just like he was, his balls emptying into the warm cat throat.
Onyx felt faint as he was held there, forced to drink so much of his naughty t-rex's seed. He felt himself slowly fade, his vision becoming white. The intensity of his own orgasm mixed with being held into his lover's crotch was too much. He began to drift, slowly whiting out before the dick was pulled from his maw. The cheetah gasped and coughed hard as Barney painted his muzzle with the last of his cum.
The two adults stood there breathing hard, the cub still impaled by the cheetah cock panting as well; all unable to move or say anything quite yet as they recovered from their amazing orgasms. 
The little mouse girl was the one who broke the silence. "Wow, that was a fun game! I wanna play it again!" The cheetah moaned, his softening dick quickly filling with blood again, causing him to throb inside the little girl. 
Barney smiled and put a paw on her head, ruffling her hair. "Oh, I'm sure my little girl would love to! She loved playing with you so much!" Onyx began to slowly hump into her causing her little muzzle to gasp. "And if you love playing with her, that makes you two girlfriends!" Barney smiled up at the lust filled eyes of the cat. "Isn't that right?" Onyx nodded frantically, his thrusting increased as he took the toddler with all his need, her little moans driving him crazy.

After a bit more playtime, and the kitten's balls completely emptied, it was time to say goodbye. Barney ran off quickly to find a clean diaper and some wipes to clean her up with, leaving the cat and mouse alone together.
Onyx didn't really know what to say or do, he'd just spent however long filling her immature insides with his cum. How was he supposed to say anything?! He looked around awkwardly, grabbing some paper towels and wiping off his own cum covered fur. He would have wiped her down too, but he knew better. If he smelled like sex that was whatever, but she would need those wipes to at least hide it a little bit.
She was sitting up on the table staring at him and as he sat to wipe down some harder to reach areas. She slid close to him and laid her muzzle on his chest. His heart started racing and he looked down at her small head. He reached his paw up, rubbing her back. She wasn't upset or afraid or anything, she just seemed happy to be close to him.
Looking up, she caught him staring down at her and smiled. She sat up and looked back in his eyes. "You're my girlfriend!" Her tail started swishing happily, Onyx blushed at that thought. He didn't know how to say no nor did he want to, so he nodded his head. He couldn't get words out, staring at her and swallowing. 
Giggling, the mouse girl stood up on the table, fully naked, her crotch dribbling the cat's cum at her feet. The cheetah stared into her eyes and she smiled. "I always see mommy kiss her boyfriends at the end of the night, can we kiss?!" She bounced on her feet excitedly.
Blushing, the cheetah nodded slightly. She puckered cartoonishly, far away, not understanding how to kiss quite yet. Sliding himself close to her, the cheetah's muzzle tip met hers. But, instead of just the peck she was expecting, his paw laid against the back of her head pushing her in closer. As she closed the distance her muzzle relaxed and she received her first real kiss. Her tail raised stiffly and her body stopped bouncing, all her energy and focus went to the new feelings. The cheetah's tongue pressed into her maw, exploring her tiny muzzle, her tiny tongue and her tiny teeth. The two kissed for what felt like an eternity, the two of them melting together into one being of attraction until Barney opened the sealed door with his magic, catching the two playing tongue twister.
"Well, isn't that just precious!" Barney smiled, closing the door behind him, fresh diaper and wipes in paw. Breaking their kiss, the cheetah blushed, his cock already escaping from his sheath, pushing into his diaper front.
"Can we play this game again sometime?!" The mouse girl laid back as Barney prepared the change.
"Of course hun." He wiped her cum filled slit slowly, making sure to rub over her clit to make her squirm. "I know I won't be able to keep your girlfriend away for long! We'll play again soon!" He softly murred, and looked over at the cat. "Won't we, my cub fucking little kitty?"
Onyx slowly nodded, his bulging diaper front already answering for him. "Uh huh, we'll play lots!"
The mouse squeaked and clapped her hands. Before she knew it she was taped up and ready to go. She smiled and sat up, thanking Barney as she gave another hug to her girlfriend. Onyx picked her up and put her down on the floor before walking over to the door. As he did she grabbed hold of his paw.
"Daww don't you two look adorable!" Barney smiled, causing Onyx to blush looking back at his dino mate.
They heard a noise from outside- a banging on the door. Onyx stiffened, ears and tail lowering until he heard the voice of a little kid. "C'mon, are you done? I gotta goooo!" Sighing in relief, his body untensed. Barney grabbed the door handle and opened it, a 5 year old bear cub stood in front holding his crotch trying to keep from wetting himself. Onyx and his little girlfriend walked through to the outside as Barney held the door. 
He didn't follow the pair, though. Smiling at the cub as he held the door, he mmm'd. "It's all yours kiddo! And… you're all mine!" Looking back at the two holding hands he began closing the door with him on the inside as well. "Give her a nice walk home, I'll be a bit!"
Onyx stared, blushing hard as the door closed shut, knowing his dino was going to play with the innocent cub that just walked by. He must have gotten lost in his thoughts as he felt a pull on his arm, the little mouse pulling him to walk her home and show him where she lived. He squeezed her paw and turned forward crinkling next to her as the two new lovers walked off together, looking forward to hearing about what went on in the bathroom after they left.
