Spermatosaurus Mutations

For Mohrahk

By Draconicon

It was the first time in years that the sergal didn't feel horny enough to fuck an anthill, and Mohrahk honestly didn't know how to feel about that. It was like he had been completely deadened to his sexual needs, and while that was going to feel a bit creepy if it stayed that way, at the moment, it was a relief. The fact that he didn't want to rape every female that he saw...well, it left him feeling at least a little bit better about himself.

He walked on bare paws down the street, taking a few moments to actually smile as he watched people go by. Sure, he was wearing half-drenched sweatpants from the walk down here from Vasilisa, and sure, he was still a bit messy, but he felt like things were actually turning around. The urge to hunt, the urge to rut, the hypersensitivity that had been driving him through the roof were no longer there. He was...

Well, normal was a bit of a stretch, but it was better than it was. Even his balls felt like they weren't quite so much bigger than they had been, though he blamed the employee back at the agency for that. Whatever sort of registration and extraction they had going, it seemed to be working.

The sergal walked down to the tram station, pulling the fare money from his pocket to make sure he had enough before sitting at the stop. It was comfortable enough, though not perfect. The benches were hard, not to mention cold, and there were puddles aplenty to make his feet feel like they were freezing.

But nothing to ruin his mood. Nothing to take away the feeling that he was...

Sniff. Sniff.

The sergal blinked, rubbing his nose. There was a scent on the air, and not an unpleasant one. He turned his head, his head tilted back as he tracked it coming around the bend. He cocked his head to the side.

Then, the vixen that was making it stepped onto the platform.

She walked by, her tail flagged up high over her track pants, and almost instantly it swished towards his face. The smell, the overwhelming stench of a woman in heat hit him like a slap in the face, and he gasped before he could stop himself.

Almost instantly, the effects started working him over. The medicine was helping a bit, but not nearly enough for his tastes. His cock was starting to rise again, and he swore it felt like every remaining sperm cell in his balls were waking back up, spinning around down there and getting more and more active.

It didn't help that, when he looked at her, he could almost tell that she had been a mother. There was something different about the smell, like an older, more experienced scent to it. The sort of scent of someone that had borne children before, and was ready to do it again.

Mohrahk rubbed his nose repeatedly, trying to keep the scent from going any further in his brain, but it was still there. Every time she twitched her tail, he could smell it getting stronger and stronger. His cock had gotten half-hard and was trying to get harder, the stiff thing trying to fight against the medication and get even bigger. He groaned, shaking his head again and again, the woman ignoring him as she pulled out a phone and flicked through it.

No...no...

He shook his head again, on the verge of slapping himself until he remembered the medication in his pocket. If one pill wasn't working, then he'd better use two. That was the way that these things worked, right?

Opening the pill bottle with one hand, he flicked another little pill out and swallowed it, hard. There was the same bitter taste, but right behind it, there was the feeling that he needed. That blissful sensation of relief as he felt his cock going back down, as his balls stopped churning. It left him with a heavy feeling in the pit of his stomach, but at least the urge to jump and rut died with it.

The tram arrived, slowing to a stop in front of him. The vixen stood up, getting on it, and Mohrahk winced. With how close that had been in the open air, there was no way that he was going to risk taking the tram with the doors close. He waved at the driver, saying he'd wait for the next one, and watched the tram head off.

He sighed, shaking his head. This was going to be a long day.

He'd ended up skipping two more trams before a third one came along with no females in need on it. The pill had long since given up, and the little breezes here and there kept bringing him hints of heat. He kept thinking that he was smelling someone right around the corner, and he kept having to shake his head and keep moving on, brushing his own scent around to try and mask the worst of it.

It worked...kinda. Not well, and not completely, but better than nothing. At the very least, it made sure that he didn't have to focus on them as much as he did on his cock.

He was three pills in, three pills in less than two hours. That had to be a problem, considering that they only wanted him to take one every four. What the hell was going on with him? Why was this not working?

Vasilisa. He needed to talk to Vasilisa.

Almost there, now. Her place was right down the road, and he didn't smell any other males in the area. That meant that she wasn't entertaining, or that she'd have him wait on the porch the way that she'd done other times. She'd be ready for him. He hoped. He really, really hoped.

Around the corner and up the steps, and then at her front door. The sergal lifted his hand, knocked on the door with the back of his knuckles.

One, two, and then the door opened before the third. The dark-furred feline smiled at him, running a finger along the underside of his chin.

"Mmmm, it's about time you got back."

"What -"

"Get in."

She grabbed him by the balls, pulling on them just enough to shut up any question that he might have had. The feeling of her grip didn't help the urges he was trying to hold back, either, particularly as he shivered, gasped, and humped against her grip as she dragged him through the doorway.

It had barely closed when she stopped, reaching down and patting his balls again. They bounced slightly in his pants, but she looked...disappointed.

"What happened? These were bigger."

"I...you had me go and order them to do an extraction, remember?"

"They extracted more than usual."

"Yeah, and they told me about the...the Spermatosaurus."

"Oh, yes. That. Forget that," she said, waving her hand.

"But they said -"

"They are not as knowledgeable as they think they are. And they are more focused on 'prevention' and 'cures' than they are on the truth."

He knew her well enough to know when she was annoyed, and he knew better than to argue right then and there. The powers of the Kotyavr were not to be trifled with, and the last thing that he wanted was to tempt her to use them on him. While he was never clear just what she could do, he didn't want to see if there was something she could do in anger.

She turned back to him again, then pushed his pants down. She didn't even look down as she did it; she just grabbed them and yanked. The sudden cool air on his cock should have made it go down, but no. It was still just as stiff, more than half-hard despite all the medication in his system, and Vasilisa was teasing it, running her fingers along the base of the shaft all the way up towards the tip.

He had been scared by the barbs before, but she had no worries about them. She seemed to know they were there, and stopped her hand just before they would have touched. Moving them up and around, she tapped her fingertips against the head of his cock, rubbing them down again, smirking.

"Don't worry about what you can do with this...worry about what you need to do to satisfy me."

"But...but..."

"Mohrahk. I'm giving you free rein to breed me."

His cock just about jumped off his crotch as she said that, throbbing hard, the barbs stiffening and growing a bit longer. Yet, at the same time, something else changed, too. He swore he felt his tongue...his tongue was growing, too? And there was much more drool in his mouth at the thought of -

"Ah!"

Once more, the dark-furred feline had him by the balls, holding him still, her fangs showing past her lips as she gave him a snarling grin. She pulled him close, his cock sliding against her belly, the smooth fur stroking him better than her hand had.

"You're going to breed me...or at the very least, you're going to try. Try, and try, and try again until you can't move. You want that, don't you?"

Mohrahk gulped at the thought of being on top of the sexy cat for that long. Sure, he had imagined it more than once, even entertained the idea of being her best stud, but he had never imagined that she'd allow it. The idea of his cock being buried inside of her, the fact that she would let him rut her again and again, and then ride him to drain him more...

All the exhaustion from the time at the agency was gone. He could feel his balls trembling, churning, and he swore that they suddenly dropped, becoming heavier than ever. He hissed softly, a silver string of something that wasn't spit sliding out of the side of his mouth.

Vasilisa smiled, pulling him by his balls. He followed, his breath coming in harsh pants, still drooling. She pulled him from the hallway all the way to her bedroom, and somehow, she seemed to be slipping out of her clothes as she did it. He saw her breasts, looked down to see her pussy and the slimy strings running from it to her panties. He saw the way that she teased him, flaunted herself as she turned at the last minute and climbed on the bed.

And as soon as she opened her pussy for him, holding her fingers against the outer lips, he was lost.

Moh leaped for her, grabbing her by the hips and ramming his cock in. One thrust, two, three before he found his rhythm, a jackhammer that pushed in hard, fast, and deep with every thrust. He growled, unable to help himself as he leaned forward, swearing that his body was on autopilot as he humped into her warm, wet depths. She moaned for him, and he went with it, the rut coming to him and seizing control.

Every thrust was met with a wet squeeze, her inner depths holding him tight and refusing to let him go. They did, eventually, his barbs raking over her inner walls, making her squeal with pleasure. She arched her back every time he pulled out, and he started emphasizing that, slowing down just a little as he pulled back, and then slamming in hard and fast. It seemed to work, as she moaned for him.

But he couldn't hold onto his self-control for long. He rammed in again, and again, each time faster than the last, until the rhythm was gone. All that was left was the rampant humping of the beast, her body thrusting back to encourage him, her moans a song to keep him motivated. In and out, in and out, that hot, wet tunnel dragging his cock in deeper, and -

His balls. His balls were definitely growing again. Moh tried to slow down, thinking something was wrong, but the Kotyavr grabbed him by the balls, pulling him forward again.

"Don't even think about stopping..."

Just like that, the urge to slow down, the caution that the swelling feeling had given him, disappeared. He needed to rut, and so rut he did.

They changed positions again and again. Sometimes, he was on top. Sometimes, she was. Always, his cock stayed inside of her, swimming in a pool of his own seed, one that was constantly getting added to as Vasilisa encouraged him, teased him, made him cum again and again and again.

For all that he was cumming like mad, his balls were not shrinking. If anything, they were slightly bigger than when he had started, and still growing, and he was still all too aware of the movements of his own sperm. They were eager to strike, eager to seek out the woman on top of him. They wanted her pregnant, just like he did.

Another shift of position, this time with her on top. He grinned at her...and then...then he frowned.

Something was wrong. The light was different. They'd been fucking for a long time, but the room shouldn't have been dark. The sun would still be up, and she had a window, and the curtains weren't closed, and -

She's glowing...

And it wasn't magic. It was heat. He was not seeing her with normal eyes, but with heat vision. Everywhere else in the room was orange or blue, while she was red. He strained to open his eyes, but they refused.

"Nnnngh!"

He tried to scream, but all he could do was bark. He slapped his hands down, and they were paws.

"Moh - Mohrahk!"

He threw her off of him, amazed that he had the strength. She fell to the floor, and he jumped for the door. The half-transformed sergal was almost there when something froze him in place.

"Stop. Stay!" Vasilisa shouted. "You...you're not leaving...not like that..."

The End
