Matriarch and Omega
When Obi first laid eyes on her, he knew he would let her do almost anything she wanted to him. It felt like a distant dream at the time to even imagine the two of them together at the time. He was a modestly-built hyena. Athletic, pretty well-hung. Plenty going for him.
But Sekai, she was the utter embodiment of all that was sexy for their shared species. Hefty. Thick. Absolutely the matriarch of any group, any room she happened to be in. Hips so wide she had to squeeze them through doorways. Breasts bigger than his head each. Everything about her a mix of powerful, impressive muscle and soft, warm, almost motherly curves.
Most notable of all, impossible to miss, was that absolutely enormous cock of hers. Pitch black skin was stretched taut over its many inches as it throbbed up between her breasts, dripping a titillating glob of pre loaded with the musky pheromones that drove his instincts wild. For all his confidence, for all his occasional moments of control and dominance he had with others, one huff of her and every part of his body screamed 'submit'.
So he did. Obi remained sprawled there, his arms outstretched as she clutched him by the wrists, holding him flat where her weight alone didn't suffice. Her fingers dug into his forearms, pressing tight to the muscles to the point his hands had gone almost numb. Sufficiently incapacitated by her power and her size, he could only squirm beneath as she gave slippery grinds of her fat shaft back and forth on his.
Both of them were so worked up he could hear the slickness of their dark black dicks rubbing on each other. Coated with a sheen that was mostly pre, but also dabs of sweat, adding to the overall intoxicating haze of musk that came with her lusty frotting on him. He was happy to let her frot him all she liked, until he was soaking in her marking cum, but he saw a look of ambition in her eyes. Something glimmering in those violets, as her toothy hyena grin spread broader across her lips.
"You know what I would enjoy?" she warmly asked him, keeping him clinging to her every word.
"What's that ma'am?"
She smiled and gave his face a lick, steaming him with her hot breath, keeping him in suspense just for a few seconds. It was enough to get him squirm, his legs tensing up with spasms, absolutely needing to know what she wanted so he could fulfill her every desire. Finally, she just leaned in close to one of his perked ears, tugging on it between her teeth. She spoke in a low voice that sent a tingle right down his spine, to the base of his tail.
"I want you to fuck my cock. Empty your balls into mine. Feel how big mama 'yena's dick is compared to yours. How do you like the sound of that?"
Obi just gave a sharp giggle. A fellow hyena like her knew what that meant, as silly as it sounded. He nodded to be sure, and she licked his face again.
"Good. I'm going to squeeze over your every inch until you cum for me, omega. I'm going to make you mine."
There was nothing he needed to do but let her use him. Just give himself entirely to her pleasure, and get rewarded with his own. She shifted on him, still holding him down firmly. Grinding, slicking, dripping all over his fur. He could feel her musky mark upon him. It sunk into his skin, ensuring everyone else would know, hyena or not. He belonged to his matriarch.
Her proposed idea took a little tricky movement, to be certain. But he could tell she'd down this before. An arch of her back, raising that thick spotty ass of hers right up, and she got them both in position. He could only whimper. It was an embarrassing sound to make, but there wasn't much more he could do when he felt the first squeeze of a broad, tight cockslit spreading right over his entire shaft.
People called him big. He didn't think so himself, but he was better hung than many other males. Compared to her, he might as well have been female. She enveloped him in slick, intensely hot hyena cock, burying his length in hers right down to his balls. For all his size, he didn't even make a bulge in that fat piece of pure hyena meat.
She began to thrust, and thought she had called it fucking her, really she was the one fucking him. The sound of his shaft slipping in and out of her length as it overflowed with juicy pre was almost too loud. Slicking, schlicking, schlurking. It went right along with the tight clenches she gave on his meat with every lusty throb.
Enough positioning and she was outright able to start pounding. The angle was a strange one, with her bent right over him like that, knees planted on either side of his hips. But with her strength and experience, she was able to snugly slurp on him from gushing tip to tightening balls, humping, bucking, grinding, until a pool of their mingled pre was splattering out across his crotch and belly in their hot, sweaty fucking.
The scent of her musk just seemed to overwrite his before long. Everyone was going to know who he belonged to. Everyone would draw close to him and wonder where he acquired such a perfect mark. But none could please her better than he could. Or at least he liked to imagine.
Those were the kinds of thoughts running through his head as she thumped him down into the creaking bed. It was already strained under her considerable weight just holding the both of them. With her applying the power in her curves and muscles like that, she threatened to just break it. Send them both tumbling to the floor, or perhaps through it as she fucked his cock right into hers.
Obi had never felt his balls going so tight before. He could feel them churning up an orgasm, feel them getting ready to just fire. He never thought he'd end up cumming inside the momma hyena, but with every deftly slamming motion she made to take him as deeply as he could reach, he could feel it brewing, feel himself tensing dangerously close to simply losing total control. Or not losing control exactly, but having it taken from him by the relentless needs of the bigger, stronger hyena. The leader of his pack. Or at least his sack.
Finally there came a stroke over his shaft, the tip of her cock pressing deep against his balls, the inside of her shift clamping down all over his in every perfect way, that sent him over. There was absolutely nothing he could do, no restraint, no muscle he could strain, to keep from cumming for her. His hips jumped as if hit with lightning as he twitched and shook through climax, yipping sharply while she just deeply cackled in response. He came right down her dick, spurting, spurting, feeling like he was just unloading a continuous stream of pure seed right into her. Filling up that slick and slippery length until it flowed right down to her own nuts.
When he was done, he simply let his tongue hang free, panting, gasping, eyes going blurry. Every part of him was lit up with pleasure, working through his muscles, an afterglow of ecstasy that hit him almost hard as the orgasm itself. All he could do was lay there breathing heavy for a while, chest heaving up and down. Staring up at him as she granted him that approving grin, with all her teeth. He hadn't disappointed her by going off that quickly.
His balls still felt tight even after cumming. Almost impossibly so, pulling tighter to his body than he'd ever felt them. Only with a glance down at them did he really notice what that strange feeling really meant. It wasn't that his sack was still pulled taut to him, but rather it was simply smaller. Shrunken down in wake of that draining cumshot, hanging not shrivelled but just shrunken as her cock slorped loudly against them. He stared there a while, then back up to her and the wild, horny look in her eyes.
Her simple response was to nod as he gave that disbelieving look. Whether or not he had truly figured out what was happening to him, she offered no further explanation. He liked how it felt. He could tell she wanted it. So there were no complaints.
Especially not when he was experiencing a series of sensations like he'd never felt before. Every kneading suckle her shaft gave on his, and he felt just a little less male. As if she were outright changing how his mind worked, taking away all that made him brash, bold, brave. Replacing it with just greater and greater submission. It probably wasn't that complicated. She didn't know any fancy mind-control tricks. Instead, it was just him breaking. Giving up more of himself mentally as she stole away his malehood, physically.
She was sucking it right down her dick, or absorbing it, however it really worked. It was clear enough once it had some time to work on him. His balls were simply shrinking, not retracting as he first thought. He'd given her all the cum he'd ever give, and he didn't need them anymore. From hefty, bulging, down to modest and then lower. Smaller, until they were cute and tiny, barely jiggling as she kept fucking her own cock with his. Using it for her own. Stealing away his size and adding it to her own sack, padding, growing out those big fat hyena nuts with everything she'd taken from him.
It wasn't much, in truth. Even if it meant taking absolutely everything from him, it was only a little extra heft on the dark black pair of balls that swung between her thighs. A modest trophy. She wasn't done claiming it from him, either. Once his balls were shrunken down against him, smaller to the point of barely there. Tighter, tighter, and then they were simply gone.
Instead, there was just null space. Bare fur, soaked in fluids, nothing more. His balls stolen to add to her own. She wanted the rest of his package too. Still bucking, thrusting, fucking, she squeezed down even tighter on his shaft as it remained hard within hers. In a moment, he felt whatever forces they were working on his inches.
Even his voice itself seemed higher as he yipped and whimpered in submission. She was making him so very much less male with every moment. But it wasn't rapid. Just taking it from him one throb at a time, bulging out that vein that stretched all down her length. Pleasuring her with every moment of the theft. His wondering about his altered voice was confirmed when he finally spoke again.
"Are you gonna take it all?"
She licked her lips wetly. "That would please my little omega, wouldn't it? Giving away your inches for good, adding them to please and thicken your matriarch's own cock? Just think how good it will feel when I turn you over and fuck you with it. My dick that much fatter after taking yours from you. Not like you'll need it when I'm mounting your cute ass over and over and over."
His response was just a hot huff through his gritted teeth, barely able to even handle how good it made him feel just knowing he was pleasing her. He nodded and she cackled, but as much as it sounded like wicked, mocking laughter, it was quite the opposite. Hyenas had their own language, as crazy as it could sound, and that was her expressing her utmost of approval.
For the moment he still had a malehood, even if he lacked balls by then. Her every clench on him was still blissful, nearly paralyzing him, keeping him from going all the squirming and kicking he might otherwise. Not to get away, but just because the pleasure was too much. Her dick seemed almost to swallow, tugging inwards and drinking down the cum he gave her into her freshly fattened balls. With every one of those compressions, he was a little smaller. Just like that.
From well-hung, he became more modest. It was a gradual process, absorbing him through stages. Not just inches, she stole girth at the same time, downsizing him to less and less impressive with every bit she took from him. A few minutes, and he was still reasonably thick, a little above average, but she kept on working to bring him down from that.
As she made him a little less masculine with every bulging throb, he cycled through his fantasies with her and even felt those changing. Where once he might have dreamed about her lips around him, or even getting a chance at humping under her tail, he couldn't even feel desire for that anymore. Why bother when he could simply daydream of her using him, of fucking him and grinding on him, covering him with her delicious cum for him to drink and wear like a musky badge of pride?
Smaller still, until his throbs were passing through a decisively embarrassing length. Something he'd be shy to ever show anyone, so small, so useless. Something that would never pleasure anyone. He might as well not even have it. If she stopped then, it would already be an utter shift, a total rewrite of everything he loved and lusted for. But she still wasn't done with him.
He could hear her working into a frenzy. It was intimidating, but he knew she didn't mean him any harm. A rising rumble, then a snarl. Drawing out from between her gnashing teeth. Any other species might have seen it as a threat, as anger. But they were hyenas, and he knew a happy one of his kind when he saw it. She was going to cum so hard, and it was all because of him.
Not until the theft was completed though. She squeezed and squeezed, but he felt less of it every second. There was less to clamp down on, as she took away his inches, everything that he once had, that he had plunged into eager females time and time again. Now he was her female, never to feel male pleasures again and perfectly content with that if it meant serving that snarling, mighty goddess.
Finally, her cockslit went as tight as before, finding absolutely nothing to clench on any longer. She'd taken away everything, not even leaving him an inch. Balls, cock, sheath. All of it was gone, smoothed over and simply nullified as if they had never really existed. He move his hips, grinding at the air, feeling how very smooth the patch of fur was there, completely unmarked, no sign of him ever having anything there that resembled malehood. His voice was high and soft as he moaned with the new feeling.
He'd definitely made her cock fatter, but maybe it was just the extra arousal from stealing away his masculinity like that. If he had expected the gift, or the theft, to make her enormously bigger, to double the size of her shaft or weigh her balls down to the floor when she walked, he would have been wrong. But he wasn't disappointed. His contribution was just one among surely many, adding, building, pumping up the girth of that delicious hyena shaft to be just that much more perfect.
Plenty happy to taste it when she offered, he began drawing long slurps up and down its every detail as she pushed the tip up to his face. Slup, slup, slup. He went for it automatically. Servicing his alpha's dick was simply ingrained in his mind. He even wrapped his arms around it, given it was big enough to hug, and pressed his chest and middle against it, letting it grind all the way down to his voided crotch, smoothing up and down between his legs where his balls and shaft used to be. Now there was just soft fur for her to hump, to use as a runway for her gliding, dripping, enhanced dick.
He flattened his ears as he felt that certain twitch running all through it. Pumping, pulsing, bulging even bigger. He heard her snickering growl, her moan, her huff, and then he felt her sack tighten between his legs, her balls resting on the inside of his thighs, sloshing, churning up something powerful. Until it finally hit him.
The impact actually stunned him, splattering in his face as she unloaded all that rich hyena cum. Fuelled by that cock of his she'd taken. Maybe she was cumming his malehood right back on him? He wasn't really sure how it worked. What he did know was he was getting hosed down in her thick load in faceful after faceful, the sound of it almost hurting his ears as it got everywhere.
It was in his mouth, in his nose, in his everything, the musk of it all so potent he almost didn't notice at first. His senses needed time for it to really set in, for the flavour to become apparent as he tasted and smelled it all at once. And then it nearly knocked him out, blasting him with everything he ever wanted. With the exact pheromones that told his body everything was perfect, his absolute biological need sated in every single way.
Not that she was finished hosing him down. Even once his face had been coated in layer after layer of fresh, hot hyena cum. She simply went grinding down, rubbing on his chest as she kept on spurting. Gushing it under his chin, and into as much of his fur as she could until he was just laying in a puddle of it. From chest, to belly, to his newly nullified crotch. All the pleasure she'd taken from making him less male, she took out on that spot, snarling out as she finished her extended climax by milking her extra engorged balls out all over where his dick used to be.
When she was done and panting, briefly winded but no less dominating, she took him by the the hair and wiped as much off of her shaft as she could. Sweat, cum, pre. It all had accumulated in an overwhelming cocktail that bombarded his nose as she used him like a rag. There wasn't much of him that wasn't already marked in her scent, that was even remotely dry, but she used his soft head of hair like her personal rag to clean up that perfect shaft as thoroughly as she could. From top to bottom, letting him feel just how much thicker he had made it as it softened there against him. For the moment.
Then she simply sprawled with him, putting an arm around him and not caring how messy it was to cuddle him in that moment. His malehood was part of her now, but she wasn't going to just take it and leave for other things. That he could tell as she pulled him close to her chest, burying him in her hefty bosom. He cuddled in, and gave a kiss there to one breast, just above his heart as he felt it beating hard.
"Is there anything else I can do for you, ma'am?" he softly asked, his voice fully changed to something higher to fit his newfound submission.
"Of course there is, my new omega. You can serve me, please me, do everything I ever ask you until the end of time. You can keep being your sweet, pretty self while I mount you, fuck you, demolish that tight spotted ass of yours until it's the only thing you ever want." She licked his face. "But most of all, you can keep on loving every second of attention I give you in your new perfect form. How does that sound?"
Obi couldn't really articulate how good that felt to hear, so he didn't even try. Instead, he just snuggled closer, sniffing at her fur for even more of that scent he loved, feeling her warmth, her loving embrace, and the safety she provided him. There was so much pleasure to be had, so many things to explore together, and he didn't mind her change to him one bit. After all, how could an omega male like him possibly know better than his sweet and potent matriarch?
