Steven was unprepared for this on every plane of existence.

He could only stare at the sight in front of him and try to string together a single thought he was proud of. One hand was propping up his elbow, the hand of which was propping up his head. His brows were furrowed in a mix of lust and awe, but mostly deep perplexity. He'd been going to make some coffee, but that could clearly wait.

Even when it beeped its completion of brewing in the background of his thoughts, he paid it no mind. A flicker of movement Connie had made captured his attention enough for him to get a closer look.

And boy was he looking.

Connie had gone out to Little Homeschool Research and Development after waking up particularly peppy. He wished he had gone with her instead of mumbling he loved her as she jogged in with her thermos for a kiss and a goodbye.

Now, he didn't know what to do.

She didn't look all that different. Her skin was still smooth and dark, her limbs
were still humanoid for the most part. Her long hair stayed the same, she was still glowing (in the human way) from her pregnancy. He couldn't see her tummy, but he could imagine the roundness that was starting to become obvious. But the differences were uncanny... and adorable? And (he realized this was very telling of just how traumatized he must have been) incredibly sexy?

She was perched in his favorite spot to catch her in, the window seat. His fiancé had mentioned she'd be taking advantage of every chance possible to lie on her stomach before she got too big to try, so here she was loafing with a heated blanket or two pulled over her dosing form.

He guessed his Connie was comfortable. Obviously she must have been if she was asleep with no stirring or readjusting, but it only sealed the deal that she was comfortable by the fact that she was purring deeply. Not a snore, no, a deep, sweet purr that made his heart flip flop.

Suddenly he longed to touch her. It was so strong his body moved without his permission to take careful, hopefully silent steps closer. Steven loved cats, hence the giant pink asshole (Lion) he kept around. He was overcome with the urge to pet her. Sure there was a chance she'd lash out with claws he didn't know about, but if not fiancée, why fiancée shaped?

He sat an inch next to her and carefully rested his hand on her head. The purring stopped, but she didn't seem to wake up at all. Two dark chocolate brown ears protruded from her skull and pinned when he ran a thumb over them. It was so amazing he grinned like a toddler. They were velvety soft, so so soft. They twitched at his touch and he giggled to himself, rubbing his index finger with the growth of the fur there. She yawned, showing a few sharp canines before her eyes opened.

"Hello," She purred seductively.

He was speechless as she raised herself up on hands and knees and stretched the blankets off of her, revealing she was naked. Her eyes were catlike too, slitted over a heterochromia of pink and blue and vastly uninterested in everything like most cats looked.

She grinned, giving him another angle of those sharp fangs as she stretched. "What's the matter? Cat got your tongue?"

"I fear what this says about me," He mumbled. He knew his face was as red as it could get without him passing out on the spot. "I fear I'm so far gone I might not even be actually afraid anymore. I fear I may not fear at all."

"A lot of prose just to tell me you wanna fuck me like this." She chuckled and nuzzled into his lap. He scooted back eagerly to press his back against the cool window as she climbed onto him to rest on her knees so he'd be looking up at her. "You like?" She tipped her head, her tail flicking out to the side in curiosity.

"I think I like way, way too much." Sentences were hard to string together when she was looking at him like that. It was so incredible he wanted to personally go down to LHS R&D and thank them personally with a handshake and a hug. Everyone clearly needed at least three raises. His hands finally found motion and ran up her sides reverently. "You're so fucking sexy, Connie Maheswaren." He hummed as she nudged his chin upwards with her nose to litter kisses down his jugular.

"Glad you like. I was a bit worried you'd freak out," She confessed.

Had her voice always been so smooth and sultry? He couldn't have stopped it if he tried. He stared at her in horror as his cock began to strain against his boxers harder than he could ever remember.

She was preoccupied as she began rambling on about the scientific process of modifying the human body, how it was temporary and pregnancy safe. Apparently each new addition was able to pick up her brain waves and move accordingly. He was watching it happen now, her tail swished excitedly as she spoke, her ass subconsciously swaying too as she spoke with increasing ardency.

"Steven? Are you okay?" She kissed him and frowned. "You're so pale suddenly."

He stayed bewildered and silent, staring at her like she had grown new limbs but she had and it was one of the most delectable things that had ever happened to him. At least 3 months worth of childhood trauma melted away by living this moment alone. It was worth it, those three months were so worth it. He cautiously picked up her hand and studied it. She picked up on his cue and unsheathed dark, pointed claws. The elegance was immaculate, he would've thought it was just a trip to the nail salon and a bit more money spent than usual. He brought her hand to his cheek and blew out a slow breath. "Am I actually pale?"

She nodded quietly.

"You wanna know why I'm so pale? Every drop of blood is elsewhere, Ni."

She giggled. "I guessed as much earlier but–,"

"You don't get it." He gathered his courage and pressed her hand against his cock and grunted. "This isn't normal level."

She recoiled in surprise and locked eyes with the now fully aglow man. He was indeed correct, an average erection of his was, well, hard... But she typically didn't have trouble moving it. She almost could feel how much blood was being forced there simply because she'd gained a few traits of one of his favorite animals.

She grinned and batted her lashes at him. "I do wonder how my senses would interpret a bit of messing around. All of them are heightened, you know." Her hand dropped to rub over the wet spot starting to spread and he moaned.

"C-Connie... W-would it be weird if I petted you?" His eyes were closed to avoid the embarrassment but she straddled him and ground down on his bulge. She nodded against his neck so he let his hands wander freely, one down her back and one up to scratch behind one of her feline ears.

The soft mewl she made in his ear nearly  had him busting in his pants. He was too wound up for any type of foreplay if he wanted to be able to take enough time to satisfy his Connie. He had to grab her hips and lift her miserably. "Dang it. I'm sorry, but you're going to make me bust in my pants."

Her eyes studied the absolute torture in his, but her sympathy was lacking as she smirked. "Poor baby~." Her tail brushed against the hand that had ended up resting just above the base of it. His half lidded eyes broke from hers to glance at the fluffy appendage, the pink in them glowing a bit brighter. "I've never seen you like this before. Maybe I want you to ruin your pants for me. Maybe I want to indulge in an extra ego boost..."

He narrowed his eyes and grumbled, "You fucking felines and your attitudes." His big hands encircled her hips tighter and pulled her against him. "I don't even have the patience to let you try."

"Why not?!" She whined as he began to stand.

He chuckled and pressed his lips under her ear, shapeshifting just a bit to emit the kind of growl belonging to a much bigger feline. She tensed so hard he had to laugh as she went limp and her tail fluffed out. "Because I said so. Fuck around with a lion and see how that works out for you, Ni."

Looking back, he was absolutely humiliated at the state of his boxers. Admittedly, the hybrid leaked a lot, he had an eager reproduction system. If he had just let it be, he could've slid in if she was bone dry and had plenty of lubricant with all of the precum coating his throbbing cock. He'd have to wash his bottoms without fail, but at the moment he was one track minded.

He licked and kissed every spot he could reach, starting with planting a gentle kiss or ten around her cat ears. She giggled and pulled him into her, enjoying the way the head of his cock was jabbing into her leg.

"Steven, you're going to get stuck playing with my amenities every time you come across one."

He hummed and finally pulled himself down to kiss her. "You're ruining my self hate with all this kink stuff, by the way. I feel so loved and trusted."

Before she could respond, he kissed her again as if to confirm that fact. Her heart fluttered at his statement and she couldn't help but smile against his lips. "Maybe in return you could ruin my consciousness?"

The hybrid raised an eyebrow and hiked her hips up to his lips, gazing at how glossy and wet she was for him. "Wonder if you animal hybrids go into heat, too?" His tongue dragged along the length of her and she yowled, her legs clenching around his head. That sound started an inferno inside him as he started eating her pussy with unrestrained hunger.

"St-St-Steven, Steven, wait!" She was going to cum too quickly, quickly enough she might drench him. She was surprised to find hypersensitive and overstimulated were not the same thing. "Steven you're gonna make me–,"

He smirked and stretched his tongue to work against her g-spot until she was crying out with every stroke. He felt it build before he felt her orgasm hit. The trembling grew harder as her hips grinded frantically against him; then she froze. A small trickle and then a gush made his cock pulse as he lapped all of it up with no intention of slowing down or stopping until she begged.

She mewled and stuttered her hips against him. Maybe he'd had a point about going into heat, because more than anything she wanted him to fuck her as raw as he could but he wouldn't slow down. He could completely forget to worry about his own needs especially since she'd started to get a bit bigger as their child grew. "Steven, fuck me, please!"

He opened his eyes lazily to meet hers and pulled away to lick his lips. "Are you sure? Did Peri clear you?"

"Peridot won't give me anything that prevents us from our 'ritualistic human breeding sessions'," She chuckled breathlessly.

"Smart gem." He gently lowered her legs and leaned forward to kiss her tummy. "You sure it won't hurt, Mamma Cat?"

She blushed and rolled her eyes. "Ask me again when my bump is big enough to not question whether I'm pregnant or just fat. The answer is still no."

Steven didn't really hear her answer. He was zeroed in on her tummy and the way it took less effort for him to notice her bump as he stroked his cock. "Connie... You're so pretty."

"You didn't hear a single thing I just said, did you?" She asked wryly, spreading her legs further to encourage him. "Too busy staring at my tummy to pay me any attention? Steven Universe and his breeding kink, ladies and gentlemen."

He snorted and lined himself up with a bashful grin. "Can't help it. You're the one who got me into kink." The way that his cock slid in, like she was made for him, always made him flush with delight.

The throaty purr she gave him as she pulled him into a kiss sent him into a flying thrust that pushed her so far up the bed the pillow beneath her barely had protected her head from hitting the headboard.

He grinned at the lush sound she provided while she wrapped her legs around him. As much as he would've preferred to fuck her all night, his body gave him a definitive warning he would be cumming first for the first time in a long while.

Wait. He could keep going, and he would for a price, but he was going to have to make his lack of control worth her while.

"Ni." He pushed into her as deeply as he could go and she gasped, tightening at the same time.

"Yeah?"

"It's not going to be like last time, but I can't help myself." His hands found their way under her ass and gripped.

Connie lifted her hips needily. "Last time doing..." Her eyes widened. She knew what he was talking about now. It excited her so much she got creamier for him and he moaned into her neck. "You'll be careful for baby?"

He pushed up to stare down at her for a moment before letting his form change. He grew broader, stronger, taller until he looked like a Diamond. Still within human limits of insane height, but certainly regal instead of boyish. "Always." Even his voice was deeper, it hit her cat ears in a way that told her it was predatory. A part of her mind told her to go limp again, and she obliged happily.

He was now stretching her to her absolute limit, a cock even a centimeter bigger wouldn't have been possible to fit inside her and he couldn't even fit to the base anymore. No worries, he'd get her to stretch out for him. He gave a shallow thrust, sweating already with the effort it took to control his Diamond half. They had to work together as a team, with one goal in mind: getting this girl off as hard as possible. This catgirl. His catgirl.

He pushed in again and descended upon her to start taking her a bit faster and harder, the sound of their skin slapping was drowned out by the array of noises she started making for him. New noises. "F-u-uckkk Stevennnn, your c-cock is a-ah! so fucking–," She trilled and he felt her claws unsheathe at his back.

"Claw me. Do it," He demanded and pushed into her deeper. He didn't like to speak when he was like this, there was something sinister that typically kept him silent. But now he would let her know, he would tell her exactly what he was thinking. Every thrust was now ending with him bottoming out, grinding his cock against the cervix that his sperm had penetrated to get her pregnant. "Take it all while you do it." She whined and dragged them down his back, and Stevens glow began to reach new heights. "Fuck. You're. So. Fucking. Beautiful!" Each word was punctuated by a gritted teeth and near vicious thrust, but she could feel him holding back his strength for her.

Her tail had a mind of its own and swished against his balls, delivering a full body tremble as he filled her with a load and fucked it into her. The resulting climax rose quickly. She had already been about to tell him she was close, but his magical cum was as swift as his fuck and shoved her right into the ecstasy with no warning.

For what she could swear was the first time in her life, she experienced an out of body orgasm. Her soul felt like it left as the pleasure got so intense she screamed. Every sense was more aware, she was more lucid than she had ever been.

Steven pulled back to watch the way her pupils dilated and her ears pressed against her head. It was magnificent, his pregnant wife so feline a dark sound burst out of her as her claws really dug into him this time. Earlier she'd held back but as she came on his cock so hard it actually hurt, she growled at him like an animal.

Being what most logical people considered the strongest Diamond, he took that as a challenge. He pulled out and watched the torrent of fluid that was finally released onto him. Their eyes locked and he gave her a dangerous smile before flipping her over and folding her to his liking. As he pressed inside her and she made another warning sound deep in her chest, he leaned down to chuckle in her ear. "I see. If you're going to act like an animal, you're going to be fucked like one."

"I can take it, I can take it, I can–," She was going to change her tune very quickly, he swore it. He gripped her hips hard and grunted, letting the slick feel of her pussy quaking around him fuel the flames he felt licking through his body as he watched her tail twitch and tremble. It only took him another couple of minutes to get her to scream his name, and he dragged the orgasm out as far as he could.

"Again." 

"Yes!" She turned to him and bared her teeth aggressively, her canines threatening him to keep going or else.

It was a threat he could not take. He pushed her head sideways onto the bed and let her watch as his horns grew, his own teeth and nails lengthened and sharpened, and his eyes darkened around the pupils. He was out of control, and he would stay that way with those crossed eyes and her tongue lolling out of her mouth. "You make me wild."

She squirmed as he swirled his hips, loving the cream he was drowning in. Her pussy was sucking on his cock so hard he could hardly keep the pace. Good, his body felt so so good and he wanted to keep fucking this woman until she was limp with exhaustion. He wanted her completely and 100% drained and not able to withstand so much as a breath brushing up against her pussy.

He rumbled at her when she started meeting his thrusts with a strength he didn't show she possessed. He guided her faster, and she fucked him harder until his skin started to sting with every contact. Every time he was completely submerged he chuffed and snarled, losing his human vocabulary entirely. She squeaked and meowed up at him, pushing him into a mindset so desperate and feral that he leaned down to latch onto her neck with his teeth for another way to hold her in place. He was working on pure primal instinct now, and for a while he was lost to it all entirely.

He fucked her like that for so long the bedsheets underneath them were starting to turn dark with their sweat and cum but he wasn't done even when she began to shred them with her claws. He grabbed her wrists and pinned them behind her back, trying to find the correct sentence to speak. "Bad girl. None of that."

She smirked up at him and brushed her tail under his chin mischievously, a nearly hilarious feat when her eyes kept rolling to the back of her head. Now she started struggling, and struggling hard. "H-hold me down. H-h-haaaarder!"

He pushed her from ass up to completely flat against the bed and bellowed from the depths of his soul at how tight she grew around him. The windows around them shivered, and their vanity mirror shattered on impact of the sound wave he let out. He'd let himself feel bad about it later, but now he felt proud and he watched her indulge in how any struggling she did was futile. He was going to fuck her and she was going to take it. And she loved that.

With herself pressed by her lower back and shoulder into the bed, she let herself drift in and out of consciousness. She was helpless, completely vulnerable to the half primal animal, half passionate man, half ruthless Diamond fucking her so hard she was seeing galaxies instead of stars. She'd lost count of how many times she'd cum, only being able to know for sure that she would have to spend weeks rehydrating for the sake of the baby. She was littered in bite marks and his sweat was now dripping off of him and onto her as he showed no signs of exhaustion just yet. He was holding out on her though, she could feel the way he was shaking harder than he ever had. His moans rose in volume when she started shifting her entire body, praying he wouldn't let go as she lived out her fantasy of being completely at his mercy as he cruelly pounded into her. In a moment of completely falling into his mind, she felt an almost funny readjustment inside of her. His cock shapeshifted just a bit smaller so he wasn't hitting her cervix so hard. He must have been thinking of her pregnancy because a cocky chuckle burned out of him. She loved how much he bathed in the pride of getting her pregnant, he barely mentioned it but he'd been using the free use rule far more often lately. She'd walk by and suddenly he'd be taking huge sniffs of her perfume and following her in midair like a cartoon character before they giggled and he carried her to the bedroom.

She felt her body leave the bed altogether and forced her eyes to stop rolling. He was picking her up with her still skewered on his cock and turning her to face the one mirror at the end of their bed that hadn't shattered apparently. Humorously she wondered to herself if he'd gotten a stronger duty mirror for that one knowing his power could break them if he got too immersed in pleasure, but the humor quickly turned to a near perfectly synchronized moment of clarity in them as they locked eyes through it.

He smiled, just a bit, beastly and handsome and almost a little unnerving. His hair was sticking to his face, and his skin glowed with pink light so bright she had to squint a little. His horns, crystalline and pink and purple, were beginning to glow too. The pools of blackness maybe should have scared her, but to know she had tamed the inky darkness made her begin to pulse around him again as another orgasm nipped at her toes.

Meanwhile, Steven was looking down at his Connie and wondering if they could be immortal. Could he keep her forever and will his gem to keep him alive with her? The thought passed as he buried himself to the hilt again and watched her tail quiver. He rubbed at the base of it and she mewed, her pussy stroking at full force. Her skin shone with sweat and his mouth watered with the need to taste it. He never broke eye contact as he kissed and licked along it, a fiery roar croak combination reaching her ears as her taste drove him closer to completion. This was going to be big, and it was going to be loud.

Six seconds before they came together, he realized he was going to destroy their house with the force of his orgasm.

Four seconds before her pussy clamped down on him and she yowled so deeply she went from house cat to cougar, he fought through the pleasure with his bare hands to focus the little spare energy he had to bubble them.

Two seconds before he roared and filled her with a load that shouldn't have been possible, a load that he released so violently it sprayed out around him, he double bubbled them and pressed his hands against her ears.

The orgasm ripped through him painfully. It hurt, the pleasure hurt so good and he knew she was feeling it too. Thank the stars he couldn't fuse when he was corrupted–

Wrong. He'd been wrong. He could admit that to himself as two layers of bubble absorbed their cries but shattered with the effort.

A light enveloped the two as they let out monstrous sounds that shredded their voices and their fusion became so unstable that it spat them back out with him still balls deep and them both crying out with the effort it took to even stay still as they were assaulted with the release of it all because moving again might break their minds.

Steven was only able to move when he'd gone soft, and even then just barely. He returned to normal of his own fruition, thank the stars. His human body would probably have died if he kept pushing so hard. The thought of a narrowly avoided demise while pounding into her pussy made the ghost of a smile lift his features. His blurry eyes couldn't read the clock, but he knew they'd been going long enough that even though they'd started when it was light, it was dark now. But not nighttime dark, early morning dark. They had fucked all day and all night and into the early morning again. It wasn't impossible to imagine with the large areas of blackness in his memory (had he blacked out at some point?), but it was certainly the first time.

He was sore and aching over every inch of his body. His cock was throbbing even soft and his head felt like it was going to break into two clean halves. He needed to use the last bit of consciousness to heal himself.

Instead, he used every iota of power he had left to place two sloppy wet kisses to a near unconscious Connies cheeks and then flip her over so he could run his tongue along hers for more direct contact.

The savior of the Universe passed out mid motion as he tried to lay down again and slipped off of the bed.
