Twilight x Spike:: #Beastiality #Non-Con #Knotting #Mental Regression

-

Spike ran down the hallway toward the library where he and Twilight were planning to sleep for one more night. They had started keeping their return visits to this world shorter as of late but Twilight said she had some important stuff she needed to stay for and that sounded boring enough to Spike to not question further. He trusted Twilight enough if she wanted to stay, even though he distinctly didn’t like staying too long in this world.

It wasn’t just from being a dog, he had gotten used to that part, but there was something unusual that had arisen. Spike had tried bringing it up to Twilight once but he’d noticed that after so many days in this world, that his mind would start to slip in weird ways, he would get a little hazier, and he suspected that he was becoming more dog-like. So far none of it had stuck once he went back through the portal, so he wasn’t too worried about it, but it always felt weird when he was aware of it. It had been about that long for this visit but just another day or two shouldn’t be a serious problem.

Spike rounded the corner, sliding a bit on the tile and more slowly pranced into the library. He perked up a bit at seeing Twilight lying down, a little surprised that she’d already gone to sleep. By no means was it early but he was used to her staying up far too late for her own good.

“Whew. I’m a little glad that she… that she’d- um.” Spike mumbled as he walked a little closer, noticing that Twilight’s blanket had slid off of her and it revealed the girl’s naked lower half.

Twilight had never gotten fully used to this world’s strange clothes and liked to at least get rid of them while she slept. Spike couldn’t help but stare as the girl’s legs hung limply to the sides, leaving him a clear view between them.

Spike felt a little drool fall and shook his head, noticing he’d been staring too hard.

“Calm down, Spike. Twi probably wouldn’t want you to stare. Although…”

Spike’s mind felt a little foggy, probably because it was so late and he was tired too. Without realising it, he’d drawn even closer, able to clearly smell Twilight’s scent. Specifically, the scent that emanated from between her legs and it was tickling his nose. Spike felt his cock start to protrude and he blinked, shaking his head again.

“Huh, wow, I’m glad Twilight’s not awake to see this… I wonder what it would feel like- wait no. Get yourself under control!" Spike sat up and tried to smack himself with his soft little puppy-paws. It was ineffective. "If Twi knew what you were thinking. I mean, I’m a dog here! Even the thought of- of mounting her... Uh, no way, she’d be furious- a girl-dog wouldn’t mind it. Wait, how do I know that? Ugh.”

Spike suddenly realised that his hips were moving and he stopped them, glancing down at his red protruding penis, wincing at what he’d let happen.

“Jeez, I need to get this body under control. I mean, how am I even gonna take care of this? I definitely feel like I’ll need to… I need to-”

Spike looked back between Twilight’s legs, absentmindedly wagging his tail and walking up to her.

“I’m- I just want to smell it is all. That’s normal for a dog.”

Spike leaned in with his nose and poked Twilight’s entrance, sniffing her and feeling a shiver at how strong it was to his hyper-sensitive dog-nose. His tongue flicked out to lap at it, letting her musk wash over his mind in a way that made it feel numb.

“Gah! I didn't mean to…" Spike suddenly parted from her in a brief moment of clarity. But it didn't last long as her scent surrounded him. "She wouldn’t… I can’t, um… A dog wouldn’t mind. Yeah, Twilight uh… she doesn't mind. I can smell it. She...”

Spike realised his paws were already on Twilight’s hips and he started panting as he looked down at her. The tip of his cock brushed between her lips and his last bit of clarity was lost in the fog of arousal.

Spike’s hips started moving on their own and started humping, at first just rubbing his cock against her labia but after a few seconds it slipped inside of her and Spike’s tongue fell out. He started humping more vigorously, pawing at her hips for a better grasp and panting as he felt her pussy around his cock. Spike’s knot came out and Spike tried to push himself closer, pawing at her hips, eagerly humping until, pop, his knot slipped inside of her.

Spike started to whine as he felt his sensitive knot submerged inside of Twilight’s passage, feeling it swell larger. Twilight’s pussy naturally gripped him and was squeezing his knot and Spike was drooling all over her navel as he humped more erratically, the feeling in his knot triggering his pleasure to hit him all at once.

Spike panted happily as his cock started throbbing and he felt his cum shooting inside of Twilight. He had never cum with this body before and was loving the feeling, his balls trembling as his cum poured out of his cock in long streams and flowed into Twilight. The way her pussy caressed his swollen knot was incredible and all that Spike could think was how happy he was to be cumming inside of Twilight.

Spike continued to hump for a bit before realising he’d stopped cumming, just dwelling on the feeling of Twilight’s pussy. He eventually came to rest in that position, lying limply on top of her hips, still buried inside of her.

Twilight began to shift, bending one of her legs up and causing Spike to perk up again as she lazily lifted a hand to rub her eye.

Spike was instantly awake again and his actions flooded into his mind, almost as though he’d just awoken from a dream. Unfortunately, it was painfully obvious that it wasn’t a dream from his position.

What was he thinking, he just… what did he just do? Spike tried to dismount from Twilight, wincing at the realisation that his knot was still quite swollen in the small girl’s passage and wasn’t coming out anytime soon. There was nothing he could do.

“Spike, what are-? Spike!” Twilight’s eye’s snapped open, looking at her puppy between her legs as she felt the presence of something inside of her. “Spike, what did you do?!”

Twilight reached down and placed two fingers on either side of her slit, trying to slightly spread herself in vain to confirm what was there. It unintentionally squeezed Spike’s knot causing one more small spurt of cum to shoot out and Twilight could suddenly feel the mass of his hot load resting inside of her.

“Spike, I don’t- I can’t believe… what the fuck did you do?”

“Twilight, I’m so sorry. It’s this- yap!”

Twilight grabbed Spike by the waist and tried to pull him out by force, causing him to yip. Twilight also winced at feeling just how much his knot was stretching her. Once she put him back down Spike staggered to quickly turn himself around, avoiding looking straight at Twilight.

“Twilight, I swear, I didn’t mean to. I-I’m starting to revert to being a dog.”

Twilight was still barely able to comprehend what was right between her legs but she listened carefully and felt a deep sinking feeling in her gut. Spike had mentioned such a phenomenon to her once and… and she wanted to trust Spike. She loved Spike. But any thought was hard to parse as she confronted the fact that Spike’s penis was stuck inside of her vagina and that she was filled with his cum.

“Shit… It’s- it’s okay Spike. I believe you. Ugh…“

“I’m sorry Twilight. As soon as I get unstuck I’ll help you clean up… um, how long do you think I’ll be stuck.”

Twilight sighed and placed a hand to her forehead.

“Dogs tend to stay stuck for up to fourty minutes… how long were you stuck before I woke up.”

“It was at the same time that you woke up, actually.”

“Jeez… that’s just great. I mean, I guess I could just try and pull you out early.”

“But it kind of hurt before.”

“Yeah… doesn’t exactly help that this happened while I slept, so I’m not exactly wet down there.”

“Would it make a difference if you were wet?”

“Well, sure, probably. The slipperiness has got to make it easier.”

Spike glanced backward at her and after a moment leaned his head between his legs and started licking Twilight.

“Heh, uh spike.” Twilight blushed and grinned down at her puppy. “I don’t mean wet like that. I mean like aroused.”

“Oh…” Spike ceased his licking and turned to face away again, not saying anything.

“But thanks for trying. This will probably be… well, I was gonna say it’ll be weird but you’ve already cum inside of me, so no need to hold back. I’m going to need to masturbate a little to get things flowing down there. Hopefully, this will work.”

Twilight reached down and touched her clit, her cheeks feeling hot as she started rubbing it. She just had to remind herself that this was for a purpose. For just a moment, she felt kind of bad touching herself in front of Spike but she couldn’t avoid the fact that Spike’s cock was currently inside of her pussy.

Twilight kind of hated to admit it but once she started stroking herself more earnestly and felt her blood flow increase, she was finding the sensation of Spike’s knot lightly stretching her inner lips, to be aiding in her arousal quite pleasantly. That was an uncomfortable thought to have but she couldn’t deny it to herself when she realised her walls were naturally starting to undulate around Spike cock and hug his knot.

“Sorry Spike if that uh, if that feels weird. But things seem to be waking up down there so this should start working soon.”

Spike didn’t respond but just stood there, lightly wagging his tail.

“Spike?”

Twilight tapped him on his butt and he glanced back over his shoulder with a smile. He staggered to shift himself back around and placed his paws back on her hips to look up at her. Twilight frowned at the way spike just looked up with his tongue hanging out like a… well like a dog. It was pretty clear that he was losing control again, which worried her, but her best bet was to keep working on her wetness.

Twilight stroked her clit a little more quickly, though it felt kind of awkward now with Spike watching her. That is, if it could get any more awkward than it already was. She felt herself twitch again and involuntarily squeezed Spike’s knot. Spike seemed to noticed and whined a little, leaning down to nose Twilight’s finger, letting his long tongue come out to lick at her mound. Twilight blushed and moved her hand aside, watching as spike began licking her clit and she had to admit that it felt amazing, so she didn't stop him. As spike got into it, Twilight noticed her pussy was twitching more often, which was a good sign, but Spike seemed to struggle to focus as she involuntarily massaged his knot. He stopped licking her and just looked up, happily panting and Twilight just waited a moment to see what he’d do. Her mouth fell open as he just started humping her again.

“Oh, come on, Spike! Your knot hasn’t even gone down and you’re already humping again?”

Spike, of course, didn’t respond, pawing at her hips for a better grip as he humped frantically. Twilight sighed at the display, thinking through the situation. She wasn’t really an expert on dogs but she hoped that if he really emptied his balls that it would cause his knot to go down sooner. And even if that wasn’t the case, based on what Spike said, once he cums then her spike would return to her.

“Damnit, Spike. You better feel lucky that I love you this much.”

Twilight reached down between her puppy’s legs and felt his balls, gently holding them in her fingers and rubbing them, making him whine while he humped into her.

“Do you like that, boy?”

She moved a little further and felt the very base of his cock and where his knot began, lightly rubbing it and carefully pushing on it. It slid further inside of her and Twilight gasped, surprised by the sensation of Spike knot suddenly pushing against her g-spot. Twilight just stared wide-eyed down at her mound, overwhelmed by the wholly new sensation as Spike’s knot even seemed to swell a little bit bigger, stretching her passage and pushing constantly into that most sensitive spot.

Twilight’s pleasure was coming on so fast that she didn’t know how to handle it, leaning back on one of her hands and just watching Spike hump her with her mouth agape. Spike just smiled and panted, seeming like the happiest puppy in the world to just keep humping her, totally unaware of how intensely it made Twilight tingle between her legs. Twilight felt no control over her orgasm as it crashed into her.

Twilight threw her head back and moaned as she came, her hips quivering and her pussy contracting, crushing Spike’s knot inside of her. Spike reacted immediately and started whining, not even slowing his humping as his cum begun to pour inside of her. Twilight was amazed by the heat of Spike’s cum as it poured out into her and added to the growing pool within her depths. Twilight was being overwhelmed by all of these new sensations that wracked her brain, and her orgasm seemed to have no end in sight as her contractions continued to press her g-spot into Spike’s knot even more tightly, thereby drawing even more cum out of him.

Twilight lost all sense of time for a moment, lost in her own world of animal pleasure. Twilight gawked down at Spike, having calmed down between her legs. And while her orgasm had faded enough that she could think, his knot remained ever-present pressing against her g-spot, providing a constant sensation to her and just waiting for her sensitivity to return to overwhelm her again. She met Spike’s eyes and he was clearly back to his usual self as he looked worried.

“Hey, Twi, are you alright? Maybe I should just try and pull out again.”

“No no!” Twilight leaned forward and placed a hand on his back. “Don’t worry, Spike, I’ve decided to just wait it out. Let’s just relax.”

“Okay… sorry about all this. I can’t wait until we can get back home and everything is back to normal.”

Twilight eye twinkled at the mention and she smiled at Spike.

“Say, Spike. Just out of intellectual curiosity. Do dragons have knots?”
