Sexy Brain Parasite Story

Annexation

"Twilight, I'm like totally okay with that."

"I guess I just—Maybe I prefer being told what to do." The words were nonetheless spoken by Twilight into the fuzz on Tree's mons pubis. Down a bit further, thanks to Tree's more equine state, Twilight found her vulva. Thick lips were shaped like an upside-down droplet. Experimentally, Twilight reached out with her tongue and ran it along the cleft between them.

"Would you mind," Thunderbolt asked, "If later was now? I promise not to interrupt."

Twilight's head snapped around to look back at Thunderbolt. He seemed huge, but she still had the undeniable feeling of comfort and safety with him. He, she realized, would help her with her confidence problem too. "Y-Yes."

Positioning himself behind Twilight, Thunderbolt blew a little stream of smoke from his left nostril in excitement. Bracing each wing against the ground, Thunderbolt reached out with one huge talon and gripped Twilight's right thigh, while he used his thumb to firmly push her dock to the side.

The grabbing of her rump made Twilight's eyes widen, but when Thunderbolt's tongue found its way to her cleft, Twilight shoved her snout forward against Tree Hugger's and moaned into the woman. She'd been right, Twilight realized, this was exactly what she'd needed. Lapping and licking at twice the rate of Thunderbolt's slow tongue, Twilight could let her worries and anxiety leak out and away.

"Hey, looks like you're a little more into things now. Like, I guess that was my bad—you needed some warming uhhhhhhp—" Tree's back arched as Twilight dug her snout in and invaded her vulva. For several seconds Tree couldn't focus enough to do more than moan out her delight at Twilight's enthusiasm, but at last she propped herself up on her arms and looked down her body at the mare between her legs.

When Thunderbolt's magic tongue left her body for a full stroke, Twilight let out a whimper of need, only to almost squeal when it instead delved into her anus. She'd been so relaxed and open to him that it had never occurred to her he might go there until he did. For a few licks she shifted her hips at the intrusion, but when he shoved the length far enough to get all the way to the back of her muscled cavern, Twilight let out a more hungry, needy moan.

The more Thunderbolt worked his tongue into her rear, the more Twilight felt her empty vulva start to ache. She wanted more, but he seemed determined to only service her anus. Not noticing that her horn had started glowing, Twilight kept up her own ministrations on Tree, barely aware that her orgasm was almost upon her.

Her eyes widening, Tree watched as motes and streamers of magic left Twilight's horn and spread out, but once a few touched Tree, they all seemed to focus upon her. "It's like—like I'm connected to everything, man…"

Tree Hugger's own magic was spreading not just through the creatures and people in the surrounding area, but those she felt a closer bond with. More and more magic flowed into her, and Tree could feel it filling her up like a balloon. Unable to let out flow out, she fell to her back on the ground as Twilight continued her ministrations.

The first Twilight knew of her orgasm was when it hit her full force. One moment she was coasting on the strangest pleasure trip she'd ever had, the next her body was on fire with a rush of pleasure. It seemed to rush up from under her tail to flutter through her body and exit through her mouth as a deep, guttural moan.

Thunderbolt, of the three, had the best view of what was happening. He watched as the mare whose ass he was eating out started to climax—he could feel her muscles clamping around his tongue, too—and her horn lit up bright purple and a huge burst of magic shot out of it.

Right into Tree Hugger.

Already full of magic, Tree Hugger had no hope in containing the rush that now hit her. With a happy laugh, the free-spirited girl let her own orgasm consume her as the magic rushed out in a wave. Though the magic was pouring out of her still, Tree felt some of it settle upon her like a comfortable weight.

Thunderbolt slowly withdrew his tongue from Twilight's rump and sat up to his full height. He towered above the two females, but it gave him a chance to look them over. Twilight looked much as she did at the start of their little fun, though she now looked a lot more relaxed. Tree looked different to her old self—now sporting a more rounded form and hooves where her hands used to be.

Panting, coming down from her magical high, Tree Hugger could already feel the changes in her body. She felt more alive, however, and held up what used to be a hand before her face. "Whoah. Groovy." Flexing her new hoof, Tree tilted her head to the side and willed herself to change.

Tree's hooves became hands and her chest started to swell out again. She stopped there, liking the feel of her fuzzy body. "Not to harsh your buzz or anything, but what just happened?"

Stretching and dropping back his more comfortable all-fours, Thunderbolt shrugged. "Don't know. Eating ass, Twilight blasted magic, you changed. Looked good."

Tree shivered and raised her arms up into the air. "It, like, felt amazing. I was connected to so many people. So how do you feel, Twilight?"

"I-I didn't know you could—I mean, I'd read about anal orgasms, but I thought they were all just, well, stories. So, uh, what now?" Twilight looked between Thunderbolt and Tree.

Thunderbolt curled his draconic features into a smile. "Wanna fuck more?"


Pressed against Spicy's side, Rainbow looked almost as relaxed as could be. They were both still watching Braeburn cooking on the grill when all three of them felt a tingle.

Shivering at the touch of magic, Rainbow sat upright and looked around. "Do you feel that?"

"Yeah." Spicy drew his wing back from around Rainbow and tried to pinpoint what felt odd. His body quickly started to pony-up more than his baseline. With his wings growing and his legs resembling pony limbs, he was at a similar state as the evening they'd all fought against the sirens. The tingle got stronger, then a lot stronger, and then he felt the wave of magic slam into him. His body felt a little more rounded and his hands curled up and balled into hooves before his eyes. "What the—?"

Braeburn's cute pony ears and longer hair changed as well. He felt his body shrink and his hair gather up to the top and back of his head like a mane. As the big wave hit him, he felt new strength pour into his muscles.

Rainbow Dash tumbled forward off her seat as the wave hit her. Her hands changed to hooves and her chest flattened completely. It took her several seconds of standing comfortably on all fours before she realize how comfortable it felt. Her human instincts tried to kick in and she jumped up to two legs. Despite how logic said it should have felt uncomfortable, she found herself similarly at ease standing like that.

All three looked at each other and while Rainbow and Spicy let out sighs, Braeburn let out a very country-sounding whoop of excitement.

"Woo hoo! We almost all changed completely!" Braeburn froze in place and turned to the side. Very deliberately—though not quite as deliberately as in a show—he pulled down his pants and swished his tail behind him. "I got a proper, pony tail!"

Rainbow's attention was drawn from her own changes to the very tight butt before her. It was so much of a distraction that she managed to forget she'd just had a serious downgrade in manipulative dexterity. She let out a happy sigh. "Maybe you should compare asses, Spicy?"

"You just want to see both our butts together. Well, you can, but it needs to be a three-way contest." Spicy stood up and reached down to shuck his way out of his pants. "Oh, hey, I have a horse cock."

There wasn't a phrase more likely to have Braeburn spin around as what Spicy had just said. Staring at what lay between Spicy's legs, Braeburn felt more possessive than ever for his sub. "Spicy Hot, you've made me the happiest guy in the world."

Moving around behind Spicy—stepping out of her own clothes to do so—Rainbow crouched a little and reached around each hip to press her hooves gently against Spicy's new sheath. "What have we got here?"

Spicy laughed and stood proudly while Rainbow slowly rubbed his shaft with her hooves. "I don't know if this is doing anything for you, Brae, but it's definitely working for me." It was obvious it was, of course, what with his shaft now poking out of his sheath and getting longer by the second.

"Ya know, I wasn't all that sure about having a girl in the bedroom with us, Spicy, but there's something about her that makes me appreciate having someone to share your subby little self with." Walking froward and crouching down, Braeburn shuddered at the growing shaft before him. There was a musky aroma of it that made him want to dip his head down and suck his way to heaven. "Let go of him and get around here so I can look at you."

Bringing her hips forward to give Spicy's butt a playful hump, Rainbow stood back up. "It's kinda odd, the hooves I mean. I hope this doesn't stop me being able to drive." She kissed and nuzzled the spot between Spicy's wings before walking around him. Rainbow had never been the tallest of the group with her friends, but now she was far shorter than both Spicy and Braeburn—her head only coming up to Spicy's shoulders.

Surprise registered on Braeburn's face. He looked at the smooth chest of Rainbow and down her body. Between her legs was what used to be on her chest, and like when she'd been more human, there was nothing to her teats—no swell and definitely no mounding. Reaching out, Braeburn held eye-contact with Rainbow as he touched her chest. It was impossible for Braeburn to keep from smiling. "You know, I don't think I've ever met a girl like you. So you're going to turn all the way into a pony eventually, right?"

Rainbow could feel Braeburn's fingers tracing the strong muscles that crossed her breastbone that linked up with her wings. "I mean, probably sooner rather than later with how all this has been going, but yeah. Guess I'll have to make a few adjustments around the house."

Moving on, Braeburn turned to Rainbow's side and ran one hand along her shoulder and the other back to her wing. "Stretch this out for me." She complied smoothly, stretching the wing wide. "What's it like having six limbs?"

"Uh, you mean my wings?" The way Braeburn touched her wings—exploring yet firm—made all kinds of things tighten inside her.

Running his hand along Rainbow's outstretched wing, Braeburn was being as careful as he could while still making sure Rainbow could feel his hands on her. "Yeah your wings. Are they like arms? How're you curling your feathers like this?"

Rainbow turned her head to see Braeburn running a finger along one of her big flight feathers and as he did the feather curled around his finger. "I have no idea. I—I think I'm doing it."

"You might have an advantage over most of us, then, if you can curl your feathers enough to hold things." Braeburn leaned forward and ran his upper lip along the big feather. The touch was a dozen times more intimate and sensitive as his fingers—for both of them.

What Rainbow wanted more than anything else was to cup Braeburn's jaw and pull him back to her chest—what she did was slap him in the cheek. "S-Sorry. I think I'm gonna have to work on these."

"If I know how your limbs bend—how they're comfortable—I can tie them up. No more slapping or struggling." Braeburn almost bit his lip. "I don't know why I'm getting this hot for a girl. I don't want to fuck you, if that's what you were thinking, but I wouldn't mind just tying you up so you can watch me pound your boyfriend's ass."

A shiver ran from Rainbow's Dock all the way up her spine to the back of her head, then it played out as a warm tingling that spread over her neck and scalp. "Sounds pretty hot, actually. Make sure I'm tightly bound, though. If I can get free, I'm grabbing a strap-on and hunting for his ass myself."

"Do I get a say in this?" Spicy asked. Truth be told, his dick was getting longer and harder just imagining what the pair were planning.

"You know you can say your safe word at any time, batty." Braeburn turned on Spicy. He still had some height on the smaller man, and some muscle too, though he distinctly didn't want to get in a fight with Spicy Hot if he could help it. Luckily, Spicy didn't put up much fight in the bedroom. "So?"

Spicy Hot dropped to his knees and tucked his wings behind him tight, then he crawled up to Braeburn and pressed his cheek against Braeburn's abs and let out a dreamy sigh. "I promise I'll be good."

When Braeburn's hand found Spicy's head and stared rubbing at his ear, Spicy sighed happily.

Petting his submissive, Braeburn looked back to Rainbow and held out his free hand to her. When she leaned toward him and he found a handful of rainbow mane to pet, Braeburn let out a happy sigh. "Well, we need to find somewhere to play. I don't suppose your house has somewhere with some ropes and things?"

Rainbow nodded, not wanting to let words get in the way of a good petting.

"Wait. Hold up. Pussy. Can we finish eating before getting a scene on?" Spicy tilted his head enough to kiss the fingers of Braeburn's hand. "Please?"

Braeburn couldn't resist a request like that. "Sure can. Let me finish cooking up these burgers."
