1 - Silver Shield 17a - Fast Change

Fast led Silver along with a bounce in her step. "So... I got something special to show you. Now that every single pony involved's given the alright on it, there's nothing stopping me." She whipped her tail across Silver's snout, brushing it with the silky hairs and tickling with the coarseness of the individual strands. "No escape for you."

Silver let out a little laugh even as he grew nervous. "You don't need to trap me, Fast. You've had me for a--"

Fast spun on him and shook her head. "Don't even finish that! Don't even say it... I haven't had you. I've had, at best, fond dreams of getting you back, but that's not the same, not even close." She rolled her eyes as she turned back around. "But now.... Now things are different. You're mine, and I will handle my lovely stallion just right, don't worry."

"Should I kill her?" asked Nefertari, slipping between here and there to have her claws at Fast's neck. "I'll make it clean."

Silver's eyes went wide. "No! Christ, leave her alone."

Fast flared with green magic, suddenly wrapped around Nefertari in the form of a great serpent that squeezed her from every side. "Stop thinking you're the last word on fighting."

Nefertari grunted softly in the tightening grip. "So you can do something besides awkward advances... this is good." She was gone, a few feet displaced to the left. "I expect a positive report from him when you're done, or this will be far from the last conversation we have."

She was gone, and Fast grunted where Nefertari was before becoming her ruddy red unicorn self. "I bet she gives the absolute best angry love."

Silver burst into soft laughter at that, dimly remembering the dream times. "That's one way to put it, yes. She feels everything hot, even when she's trying to pretend she has no feelings. Especially then, come to think."

Fast swayed her tail as she resumed her walk. "Well you won't have that problem with me. If I'm annoyed, I'll say so."

They arrived at one of the many bedrooms that dotted the palace. They were placed there for guests, important and not. But when they were not in use, there was no rule preventing others from enjoying them.

Silver pulled a 'do not disturb' sign from his saddlebag and set it on the handle of the door before proceeding inside. "So what is it you've been waiting to show me?" His wings fidgeted a little with nervous anticipation.

"I could just tell you... But that's boring. Let's not be boring." Fast looked over her shoulder at her could-be stallion and gave a flirtatious smile before she circled around and rose up onto her hind legs, walking towards him with practiced steps. She had experience moving the biped way. "It's about time you got a taste of home."

Silver's ears went straight up. As skilled at Fast was moving, she was still a quadruped. Still a horse. It looked more funny than sexy as his mind went to every little imperfection. She was lost in the uncanny valley. Still, he smiled and didn't burst her bubble. "You're going to play human for me?"

"That and more." She reached out a hoof to brush across Silver's soft snout, trailing from the cheek towards the end of the snout. As she went, the hoof softened and split like hot wax, becoming fingers as they reached the end of his startled face. She tapped his twitching nose. "My little pony, tonight you are my stallion to ride..."

Tightness blossomed between his hindlegs at the husky whisper of her voice, the sweet scent of her breath, and the naked promise of those caressing fingers. She brought in her other hoof, still unchanged. The alien mix of the two sent strange confused signals through him and he was caught in the middle, gaping at her as his breathing picked up. "Lost?" she asked as she reached those fingers up, gently teasing the fur along until she reached one of his big equine ears and began to rub over it gently. "Skin is very good for exploring. Touching and feeling everything, and you give so much to explore..."

Silver licked over his lips. It was the first taste of humanity that didn't have strings attached that frightened him. All of his herd had approved. The only pony that stood in the way was himself, and he wasn't sure he had the will to even consider it. He leaned forward a little and nuzzled into the curve of her belly. She was still a pony there. She was still missing parts. "Will you go all the way?"

"No rush," she said in a teasing tone as she pulled his head in against herself. He felt something warm and soft press against the top of his head and he jerked back to see her chest was pushing out in two familiar swells. Each curve was capped with a thick teat, each glistening with some odd fluid.

Silver realized what it was almost immediately. Fast was making herself with foal, which included milk on top of swollen udders, er, breasts. She was becoming a vision of fertility and damn if it wasn't working on him. He sat back and felt his throbbing member slap up against his belly, as hard as steel with his mounting arousal.

She stepped in as he sat back and reached down for that excitement. Both hooves had flowed smoothly into grasping fingers, and she needed both to fully encircle that proud equine pole that she had stirred into action. Slowly she caressed downwards, pulling the flesh tight before she gripped tight and pulled back up, making it wrinkle and its owner wheeze with an almost painful pleasure. Everything in him wanted to act. She was there for him, and that meant that pole had other things to do than be worshipped, as lovely as that was.

He moved to rise to his hooves, but she put a hand on his snout and pressed him right back down despite his angry snort. "Easy there, my stallion. Enjoy the build." She brought her hands to her chest and ran them across to her sides. "I'm not even close to finished. I'm hideous."

Hideous? Silver had many objections to the idea, but his words were quelled before they emerged as she ran those hands down her sides and her form flowed like the melted butter it was at her will. She gained real hips and her waist cinched. She circled in place as if part of a dance, showing off her perfect grabbable bottom. "Getting closer."

Silver could not be so easily denied, and he was too worked up to allow it. His magic exploded outwards just to come at Fast, a blanket of lecherous silver energy. He pinched and felt over her breasts even as he embraced her. She squealed in surprise, though that sound turned quickly into a moan as she realized it was Silver's actions and not something unknown and frightening. She became as helpless as he had been as he began to devour her with his magic, feeling over every inch of her body. One mental brush found between her legs, but she was still as a mare down there. Her various openings were more behind her. He hardly cared, but his teasing of those winking lips drew her attention to it.

Those lips flowed as her equine doughnut pulled into a more human one and her pouting lips ceased their spasming jerks and became the nethers of a proper human woman. Her fur began to recede, rapidly exposing her skin, her deliciously sensitive skin. "Touch me everywhere," she breathed out even as her snout withdrew away, ceasing to be.

That was a request Silver could honor. He was on his hooves, but did not move to touch her, not directly. He had her in his silver field and he liked her there. He pressed in carefully at those altered lips, but only to expand his feel, to fill her every nook and cranny with his presence and begin rubbing her from the inside in a strange sensation that had no friction yet set the nerves on fire with building sensations. That fire he gladly stoked, watching her moan and arch her human back. She still had a tail, and hooves, but almost everything else...

He leaned in and bit at the base of that thrashing limb and she squealed. He could feel the wetness around his magic as she hit a minor peak. The tail withdrew rapidly at the reminder that it was there. He sent his magic down her legs, caressing and squeezing in abject adoration for her form until he reached where the flesh turned to hooves and he teased at the point of transition. It felt like he was massaging the hooves away as they slowly became naked feet, bare as the rest of her, save the hair on her head.

Fast was a human, entirely, completely, and she was his. Silver flashed a smile, filled with lust, adoration, and burning want. "All done."

"We're far from done," she promised as she stepped away. Her movement did not pull her from the magic that clung to her, still grabbing, rubbing, pinching and exploring. Her front was dotted with drops of milk extracted from her heaving breasts. She climbed up onto the soft bed and arched her rump up into the air. "Shall we do it like ponies?" She rolled over, belly up. "Or do you prefer it this way?"

Silver strode for the bed, his turgid length swaying with every step. His heavy balls churned with seed. He was ready to be a stud. He had been lent out by his wives, in accordance to ancient traditions that had largely fell out of favor, yet, there he was. He hopped up onto the bed over her. "I think we'll try both before we're done."

Fast burst into eager giggles as she spread her legs. "That's the right answer... I'm ready."

Silver pulled her up with his magic, drawing her even with his twitching length. With a powerful thrust of his equine hips, he pressed the sensitive organ deep inside of her. He could feel her flowing around him, growing large enough to be comfortable for the both of them even as he started to rut her like the feral animal he felt like he was at that moment. He craned his head down and nipped into the side of her naked neck, nibbling down. Her hands swept around his head and held tight to him despite the magic holding up. She tensed and hissed every time he hit just the right spot. Every little noise she made was a little victory that drove him on harder and faster.

He felt her tightening around him. It wasn't like one of her adjustments. Muscles were growing tense and the movements changed for it. He pushed despite it, eager to draw out the loudest wail from her.

He received his wish. Fast pressed tight to him as she cried out, "I love you!"

Then it was light. Too bright. Silver jerked back, almost falling from the bed from surprise. The body around his shaft convulsed in ways he'd never felt by him before. Fast was engulfed in light. Something was happening. Surprise warred with lust, but the sensations were too much to ignore and he was far too close. He exploded into her with a deep grunting wheeze of satisfaction, huge balls leaping up with every fire of potent equine seed into her changing form.

The light faded quite suddenly. Silver was not hugging a human woman anymore. He was hugging an insect. Not a changeling, something else? Fast was looking at him with alien eyes, tears growing rapidly.

2 - Crossing Rainbow Bridges 9b - Rainbows In Darkness

Twilight nosed into the darkness, rubbing her soft fur gently across his front. "Are you awake?" she whispered so quietly, she might have feared either answer.

"I am now," he replied with equal silence. The weight atop him shifted and there was a small nip against his chin. "Is that you, Twilight?"

She shuffled over his body, breathing softly against his neck. "It is, hm." She sat up on him, tail swaying against his lower belly and thighs. "I can't sleep."

He reached down to her, gently petting along her belly and sides, up to the bottom of her ribcage. He paused when she sighed at the touch, going still.

Twilight lifted her forehooves and braced them against the wall above him. "Don't stop, please. I swear, every little touch." She swallowed hard as she stretched out over him. Her slender muzzle bumped into his hand and she nuzzled at it. "There's a part of me I am quite curious to see if it reacts the same way or not. I feel like a silly giggling filly just imagining it."

He let her guide him lower with those little nudges, exploring her fuzzy form as he went. He found a shoulder and stroked down that way, following her underarm until he could go no further. He had arrived at where her thighs rested on his belly and gently explored through her fur, her tension growing with every inch. His fingertips brushed her sensitive flesh and she twitched against him. "Wow."

She whispered softly, trying to remain quiet so they didn't wake Spike. "It's amazing. I didn't expect that to feel so nice." She looked up from the way she was holding herself, still keeping her voice quiet. "Please, continue." She swallowed thickly. "For science, and friendship."

He smiled up at her and nodded. His fingertips kept tracing along her. The slow soft breaths she gave at his every motion made it impossible not to continue, rubbing a little harder and more intentionally against her skin. His own flesh grew firm, jutting up into the air as he worked. The passage he teased was so close, part of him wanted the two to come together, but betraying Twilight's trust like that felt even worse than that possibility seemed grand.

His fingers brushed past her depths, teasing her belly instead. She huffed at him and then let out a whimper. He slowed and looked at her curiously. "Are you okay?"

She leaned closer and shifted up his body with a low whicker. "You're getting shy suddenly. Lower, kindly, please." She shivered with thoughts of his fingers. "Please."

He trailed down and slipped his fingers into her fur once more. The sweet scent of her tickled his nose as he traced back to the same spot. This time, he slid past and down into her heated core. Her entire body tensed as he slipped precious inches into her very being. She squeezed around him, panting softly.

Twilight rested more firmly on him. "That feels, different than expected." She turned her head to nibble at the top of his finger. "More, if you're willing."

Brad was a patient man, but Twilight's analytical approach was wearing upon him. "Twilight, please." He curled his thumb, teasing at her more delicate nubs as his fingers probed deeper. "Let me."

She huffed softly, back arching with how far she'd moved forward. "I think we can move on from this." She relaxed against him, tail raised. "Proceed. Thank you for being patient."

He removed his hand and put it on her belly, resisting the urge to taste her essence upon his skin. There were other pressing matters, and its urgent throbbing couldn't be ignored a moment longer. He lifted her up and back, just over his throbbing length. "Ready?"

She wiggled in his grasp, making those sweet little sounds again. "Yes. And Brad?" She looked up at him with that wondrous smile of hers. "Thank you."

Brad hesitated a moment, caught off guard by her words. "Um." But there was one thing he needed in that moment, so he drew her down carefully, as if afraid she might shatter. His member slid into her waiting passage, gasping as she flexed against him, winking as any equine would do. "You're... very tight." He paused once inside her, holding her just at his hilt.

She was barely fitting him, holding him deep inside with little muscular contractions, something like a second heartbeat within her. Her tail flicked against his thighs lightly. "You're bigger than expected. I thought maybe it was my imagination." She wiggled a little, bringing more delightful friction between them.

He gasped and his hips rose on their own. "As long as it fits." He rubbed up against her in a thrust with nowhere to go. "Good. Twilight, mmm."

She just purred and wiggled at him. "Please." She tensed at the sensation of him moving inside her.

"Unfair." A familiar pony strode in, RC scowling at them. "I've been hunting him forever and you just take him like that?!"

Twilight froze at the voice, though she didn't pull away from Brad. "RC? I didn't see you?"

"And it's a good thing you didn't!" She stepped up beside the bed, reaching out to Twilight's mane and giving it a little stroke. "Little Miss Science was the first to act? Unfair. Also, I can feel you two going at it! It's driving me crazy. I bet Bella's losing her mind too."

Twilight blushed and giggled. "Oh? You can feel it too? How curious." She ground down against Brad. "Will you be okay?"

RC rolled her eyes at that. "You have the nerve to ask that while you go on ahead?" She stepped up onto the bed. "The only way to make this better is for me to join."

Twilight squirmed lightly at the thoughts RC was sending, more than a few of them involving a position involving Brad's head being buried between her hind legs. "I guess I should... participate?"

"Please," she almost whined.

Brad colored in a new way at the shared thought. "Twi, you already are." He waved for RC to come over.

RC gladly stepped over Brad and sank down, presenting her already dripping and winking nethers to him. "Go on, and don't stop. Keep going until you're both happy."

Twilight nodded and sat up a little higher. She nuzzled up against RC and gasped as Brad lifted her hind legs. "W-woah!"

She stretched out over him like a bridged to one side. She continued to stroke through RC's fur, mind filled with pleasure. Her passage twitched and fluttered around Brad's thick intruder, all while he throbbed inside her.

Brad tasted RC's passage, being almost smothered by it. In his addled state, feeling the pleasure of the two mares gently bouncing back at him, he didn't mind where he'd found himself. He kissed along her needy flesh, tasting her to his heart's content. His tongue probed deep into her, using what he could to bring her more pleasure. He sucked gently at her lips, slurping and lapping at her juices.

The way that portal yawned open, just to snap wetly at his tongue only drove him deeper as he worked his hips up against Twilight. The double feedback loop of sensation only grew in strength, and he could sense how they felt it as well.

RC groaned as she leaned against the wall and rubbed at Twilight's ears. "What are you waiting for, Brad? You felt, wow, on edge before I even got here. Don't hold back."

He sat up a little more to reply. "That was before I had two beautiful mares laying across me. This is going to be quick, sorry."

She rolled her eyes. "I'm asking you not to." She glanced back at Twilight's absurdly pleasured face. "She may pass out if we go too long." She hissed out a sigh of pleasure, her own nethers trembling. "I'm right beside her."

He relaxed a little. "Then, here we go." He bucked into Twilight more firmly, fucking into her from below. Her passage tightened around him in turn, clenching down in waves as he pressed against her depths. He could feel her working him over, seeking every possible bit of stimulation within her body.

RC cried out basically in sync with Twilight, as if Brad were fucking them both at the same time. She howled and shook with waves of pleasure as she ground herself against him. "Yes. Yes!"

Brad followed soon after, feeling RC's shared ecstasy triggering his own, filling Twilight with his seed. That didn't stop him from stroking within her, helping RC along with those sensations. At least until they all fell atop him, becoming smothered by two heaving mares.

He could barely breathe, let alone move, but that was fine. They slowly untangled and helped one another settle into the bed again. He chuckled softly and stroked Twilight's belly. "That was fun."

RC smirked faintly. "I'll get out of here before we bother some little dragon." She slid to the floor and shook herself out. "But entirely worth it." She trotted for the stairs and vanished from view.

Twilight huffed gently. "I hope we didn't bother him too much." She purred as he kept stroking her, pausing only to catch her breath when he teased over her sensitive spots. "Now you've done it."

"Hm?" He stopped and leaned down to kiss her nose.

Twilight crossed her eyes to look at where she'd been kissed. "You appear to be trying to seduce me. I hate that it's working." She glanced away and back. "So, how are you on literary works?"

"Uh?" He wasn't sure why that was relevant in that moment, but he was learning to roll with it. "Not that many? Mostly movie things, I guess."

She nodded as if that made perfect sense. "I see. And what would you say is your absolute favorite book?"

He leaned back and considered that question. "In my childhood, maybe the Berenstein Bears? In high school, I was pretty obsessed with V for Vendetta."

Both were words she didn't know, but she nodded along anyway. "I'm glad you have some. If you plan to remain in my company, expect many more books in the future. I will share them with you, and expect feedback. Is that acceptable?"

He considered what she meant, then kissed her again, making her whicker happily. "Whatever you want." He gave her a gentle hug, nuzzling into her mane. "It's okay to ask."

"Asking is good," she got out sleepily, tail twitching. "Now, let's go to sleep. I hope we didn't bother him too much."

"You did."

Twilight glanced aside at where Spike's bed was, face aghast with horror. "Spike, I'm so sorry."

"It's fine." He raised a claw, showing that he'd covered his ears. "It's not like I could get any sleep with you all going on like that."

Twilight's shame only grew. "I'm so sorry! We're going to bed, for real, right now. Promise."

Brad laughed gently. "Sorry, Spike. I wasn't expecting it either."

Spike grumbled and turned away from them. "Just go to sleep, or I'll, um, something." He huffed a bit of smoke, abandoning his empty threat.

Brad arched a brow at that. Still, it was quiet time, so he settled with Twilight and they didn't make any more noise to bother Spike.

3 - Crossing Rainbow Bridges 10b - RC's Revenge

Safely in his own bed, Brad nestled into the sheets. As nice as it had been to share time and intimacy with the ponies, having privacy and quiet was a blessing all to itself. He snuggled under the covers and breathed deep of the familiar scents of home. "Mm, this is nice." He shifted about a little, trying to find the right position. "Almost."

Something landed on his bed, making it lurch in a new direction. Brad cracked open an eye and looked around in the darkness for a moment before he felt RC's questing snout bumping against him. "Rainbow?" He knew it was her, but he was startled that she'd followed him home.

She nodded her head into his hands, purring gently at the contact. "Of course it's me. The stables aren't built to keep a pony inside if they want to get out." She rolled her expansive eyes at the very idea. "Now, hope you had fun with Twilight, but I still want my turn, for real."

He started to protest, but then paused and smiled instead. "For real?" He considered a moment. "Won't Twilight feel this, us, I mean? If we start doing anything, the secret's out."

"Then we'll stop being so secretive about it." She crawled onto the bed and slipped under the covers, pressing herself up against his body. Her fur tickled against his skin, and her heated breath warmed him through the sheets. "I'm not trying to hide it from her. Maybe she'll sneak over, but it'll be too late, as you'll already be mine." She nipped gently at his chest. "My little human."

He smiled at that and pulled her up against him, allowing the blanket to slide down around her back and rump. "So forward." He kissed the top of her head, making her grin in return. "Well, I can't really stop you from sneaking into my bed."

She looked up at him with a wicked smirk. "You could try, but it wouldn't work and you know it." She kneaded at him with her round hooves, eyes locked on him. "I don't think I've come out and say it, so I will. Brad, I like you, a lot. A lot lot. I know we've only just met, but I feel happy every time I see you, no crazy magic. I felt that from the start. I want to be with you." She stretched out over his belly and chest, wiggling gently to get comfortable. "Will you let me?"

He knew he should refuse, at least for a moment. He had other things he was supposed to be doing, right? Not being caught with RC in his bed felt high on that list, but the way she was cuddling him was exciting him in other ways, and he gently rubbed up at her, feeling more excited by the moment. "I think you're pretty great too."

She giggled at that and leaned into his strokes. "More than pretty great. We both know that." She bumped her head up under his chin, getting comfortable there. "Can I stay tonight?"

Brad pet gently across her back, thoughts of trying to banish her feeling so far away. "If you're quiet."

"That's more up to you, stud." She flicked her tail across his legs as she ground gently against him. "I'm ready to make a little noise."

Brad pressed a hand behind her ears, scratching gently as he had with Twilight. RC grinned and leaned into the attention, purring softly in return. Her gentle pawing at his body increased in intensity, grinding harder against him. He had been wearing his boxers, which did little to contain his turgid pole as it sprang free of the cloth.

RC bumped her head against his chin once more, playfully nudging him before sliding down his chest. She paused at his nipples, giving each a nip in turn, making him flinch and hiss. With a little twist, she sat up and back, pressing that ready pole against her winking nethers. "I meant what I said. Brad, I want you. I want you with me, in this world, and in Equestria."

He lifted the blankets and watched as she slid down along his body, one gentle inch at a time. He had to raise his hips slightly to help her along, his passage through her inner gates eased by the slickness that her nethers had already coated him in. Pressing into ponies was a delightfully smooth process even as she grabbed and rippled along his length, seeking to coax every inch of him into her needy depths.

"That feels amazing." She was nearly at his hilt when she finally spoke again, sitting fully upon him. Her winking flesh gripped at him tightly as she pressed him up against her depths. "I am you mare." She put a hoof at her chest. "You are my stallion, pony or not. Mmm, do what studs do, stud."

He began to slowly buck up against her, drawing himself out of her tightness before pressing back in. Each motion drove her to lean forward, eyes closed and lips parted in a very un-pony like pant. He stroked along her sides even with every motion, working her body in counter with his motions inside of her. The tight fluttering of her tunnel around him told him he was doing it right.

She gasped and huffed as he kept at her, pounding her steadily. He gripped her rump, lifting her slightly so he could get a little more range of motion with his thrusts. Each slap of their hips was punctuated by a soft little gasp from RC. "Brad! Yeah, mmm, harder." She trembled with the motions, a pleased smile plastered on her face.

The bed lurched softly.

"You know I can feel that, right?" Twilight approached them in the darkness, wings fluttering. "And it's very distracting, to say the least."

RC only giggled and nodded. "Yeah, kinda figured. Hope you don't mind. If you do, feel free to get on over here and stop me." She lifted her tail, giving Brad a clear view of their joined flesh. "Keep going, Stud."

Brad colored lightly and shook his head, still holding RC up against him with one hand as he drove into her again and again. "She came to me." He winced at the poor choice of words. "Sorry?"

Twilight whickered in a properly equine fashion. "I don't blame you. This is RC's idea." She leaned in to nose RC's cheek even as it bounced. "She's the one deciding this, and we're along for the ride."

"Couldn't put it better myself." RC managed between moans. "Besides, who's to say you can't have both? Our stallion could ravage you next."

Twilight colored as she sat on her haunches, watching Brad drive into RC with his every thrust. She ran a hoof over her muzzle, considering that possibility. "A curious idea, but I'd like to do this my way. He was tired before you arrived, and finishing you will leave him quite ready for sleep and little else."

RC let out a happy yip. "Do your worst, because Brad is doing his best."

Twilight swatted at RC with a wing. "Stop teasing. Brad, I apologize on her behalf. Kindly finish, then get your sleep." She stood up and walked around the bed. "Besides, I know you're close."

"We're both close," he managed to get out as he hammered RC hard and fast. He could feel the two mares shifting in ways beyond just his touch, through that connection they all seemed to share. Bella, curiously, was not a part of things for a change. A small part of him wondered what she was up to, but the immediate needs of the moment drove the thought out as he bit down a cry, his peak crashing upon him. He jammed RC down against him and filled her depths with his seed, even as she shuddered in turn, yipping out in pleasure as her passage clutched at him.

Both came down from their peaks together, with a satisfied sigh from RC. She grabbed him and rolled over, cuddling and making no move to separate from him.

Twilight let out a gentler sigh, her climax rippling through her in an echo of the great crash RC and Brad just experienced. "That is surprisingly almost as good even when I'm not the one involved." She turned an ear back. "We do need to figure out why that's happening, as pleasant as it is."

"In the morning." RC sighed with contentment. "I've never felt so full before." She giggled gently and nipped at Brad's chin. "Just going to sleep like this. That alright?"

Brad murmured something, but the words were entirely lost. Sleep had him in its grip.

"Ah." Twilight giggled and curled up against Brad's other side. "Can I join you? It's more comfortable than it looks."

"Yup!" RC nestled with her stallion, seemingly entirely ready to share with Twilight. "Way better than the stables, that's for sure. What are we, horses?"

The two snorted at that, and soon the room grew quiet as they all faded gently into slumber.

Elsewhere, Bella nodded at one of the ranch dogs. They communicated in the ways animals had, no actual words spoken. "I went to a special place."

"You smell different," replied the dog. She was female, tall and fit. Her ears perked up, nose sniffing at Bella curiously. "Stronger, healthier." She lolled her tongue and paced back and forth curiously.

Bella nodded at that. "I feel stronger, healthier. I feel different." Bella was quiet a moment. "I feel closer. Closer to father."

"Oh!" the dog barked out. "I want closer. Closer to father. Share?"

Bella shook her head. "Don't know how. Learning. Will share what I can."

The dog stretched out beside Bella, panting happily. "Very happy. Feel more powerful. We will be best friends." She grinned at Bella, showing off her teeth.

Bella whickered gently. She leaned down and nosed the dog gently. "Good dog." It didn't matter the language, it seemed dogs understood those two words, and the dog made happy noises at that basic fact being confirmed. "Other world, little horses. Not horses." She struggled to get the meaning out with the limited vocabulary. "You see little horse?"

"Yes." The dog rolled to her paws. "Two little horses. Wings. Horses not have wings. Why wings?"

"Not horses." Bella huffed gently. "Ponies. Ponies can help big plan."

That got the dog's entire attention. "Yes! Learn more."

Brad woke up to a knocking at the door. The worse part was that the doorknob was already turning. Dazed from sleep, he struggled to get himself upright in a hurry. "Who is it?!"

A familiar voice answered. "Sarah." She pushed in even as a pony tried to slip out a window. "What?"

Twilight slumped, her escape ruined. "Um, hello?"

"It's fine, Sarah." Brad shrugged a little at that. "We all have secrets. Don't judge, okay?"

"Alright." She eyed them a moment. "This isn't really something I can skip judging. Oh shit!" She jumped back as RC peeked out from the covers. "You have both of them. Why are you sleeping with them?"

Brad rubbed at his eyes. "My god, it's too early for this." He rubbed along Twilight's neck. "Sarah, she's nice, and warm, and soft, and fuzzy. Also, really cuddly."

Sarah took a slow step back. "Real cuddly. Right." She slipped out the door with a gentle click.

Twilight inclined her head. "She did not seem to accept that well."

RC wriggled atop the covers. "And neither will the rest. Let's get back to the stables before we're missed."

Author's Note

RC had to have her turn. Twilight is accepting of this, it would seem. But Bella is busy chatting with a friendly dog.

4 - Crossing Rainbow Bridges 17c - All Ponies Here

Bella nipped and pulled at Brad. "We're not in public." She flicked an ear away. "Away from prying eyes." She nosed at Brad's new wings. "And I really like what I see." She tossed her head about and giggled as she pawed the ground. "What will you do to me? I bet I know!"

RC puffed up her mane. "You clearly aren't as smart as you look if you don't know what's coming next." She charged in between the two. "But you're wrong even then. I called dibs on him over a moon ago!"

Twilight appeared behind Bella, bodily lifting her away from the scuffle. "RC, that was unnecessary. Can we all calm down please?"

Bella whirled around on Twilight. "I don't want to." Each word was quite clear. "I've had to be a silent supporter for Brad years before he even met RC. I want him. I am a pony, and so is he, so we can have ponies, together." She began clapping, leering at the thought of what was to come.

Brad finally stepped into the center of the room. "What if I wanted to get to know my new body better?" He shook his rump a little. "On my own?"

That brought the two mares up short, both eyeing him over. RC snickered softly. "A little tussle in the hay sounds like a good way to get used to how things move. I think we'd both be happy to help with that."

Bella slid in next to RC. "I can agree with her there. Let us show you how wonderful you are right now."

Brad chuckled softly. "N-no. I meant it. I want to explore on my own."

Twilight colored. "O-oh! Oh, you wish to engage in auto-erotic stimulation? I never witnessed a stallion performing that before."

Brad stomped the ground with a clop on the wood. "No! Twi." He sank a little. "I just meant some, ugh." He looked between the three ponies that all seemed to have some amount of dib on his love life. It didn't help that he felt like he wanted them back at least as much. "Never mind."

RC tried to look innocent, and failed utterly. "Can we watch?"

Brad whirled on her, wings flaring up behind him. "No!" He leveled a hoof at them. "Stay!"

RC attacked where she knew a pegasus would be weakest. She latched onto a wing and started gently preening over it. In her mouth, she aligned his feathers and slicked them down with a protective layer diligently.

Brad shuddered, the sensation of this entirely new, but so good. His body quivered and shook with her gentle attention, pleasure racing up and down his back. "R-RC! Oh... wow." He felt like he was in heaven, despite not even being close to being fully erect. It was like he knew, in that moment, that RC cared deeply about him. She knew exactly what he wanted and needed. It was amazing.

Twilight had stepped closer as well, gently preening the other wing. "I have heard that pegasi enjoy this—" She squeaked, brushed out of the way.

Bella was the one doing the shoving, joining RC in the preening. The two mares were quite unified in their desire to please their stallion. She pressed in on him, so close he could smell her. His ears lowered. That spicy scent was back. Her body wanted him, and his own was very much listening to it.

"Y-you're smelling better," he mumbled. The scents of Bella before were just that of a horse. He had learned to ignore it entirely. As a pony, all the rules had changed. His will to resist them crumbled as they worked on either of his wings. The world fell away, replaced by their care for him and his pleasure. His senses were filled with nothing but them and what they were doing to him. Their touch was absolute in its focus on his wing.

With a soft sigh of release, his new pony shaft sprang into full thickness, throbbing with need and desire. He panted softly at the strange yet familiar sensations, head spinning a little from the double dose of preening. "We, uh, not here?"

RC snickered gently. "Come on then." She nuzzled his throat, then turned to walk towards the bedroom. "Follow us."

"Come on!" Bella raced to be at RC's side, waving her tail at him with her vulva winking with clear invitation. "This way." She laughed as she scooted ahead of RC, aiming to be first into the room.

Twilight trotted in behind them all, smiling at their antics. "Have fun. Don't forget you have a whole new body to get used to."

Brad's eyes were on the two mares in front of him. The winking of Bella's nethers were just impossible to ignore, sexy in some strange new way he'd never experienced before. He flapped his new colorful wings, a reminder that he had become a brightly-colored pegasus. Something he was enjoying far more than he should. He trotted after them, going down the hall and into the bedroom.

Bella had claimed one side of the bed, while RC was waiting for him on the other.

Twilight followed after Brad, but stopped at the entrance to her own bedroom.

Brad moved to the bed, following that enticing scent up onto it. His shaft dripped a bead of excited fluid as he climbed aboard. He kept going, going up to Bella. "You smell amazing."

Bella squeed with delight, almost rolling into his side. "That's my estrus talking, and you liking it." She kicked her legs in little cycles. "And I'm agreeing. Please. Rut me. Rut me now!"

RC growled and got up between them, shoving Bella away with her hooves. "I claimed him first, so back off."

Twilight trotted into the room with a sigh. "Guys, really? You already have him. Let him pick, and no fighting."

Brad leaned in and touched his nose to Bella's, nuzzling gently as he bumped against her. He knew exactly what he was doing, guided by that instinct they had all told him about. "Do I smell good?"

"The best!" Bella squeaked out the words as she ground herself up against him. She wrapped a leg around his rump, her tail flicking out of the way for him. The idea of doing it on her back was a new one, but ponies were not horses, and the way he was getting in closer was all the right kinds of things. "Do it."

RC tried to shove them apart again, but Brad wasn't having it. He twisted and bucked RC off, forcing her to scramble away and slip off the bed. He was very focused on Bella, pressing his front legs over her shoulders as he fitted himself up into place. With a low groan, he pressed into her, separating her flexing vulva with his blunt-ended tool. He pushed up into her depths, shuddering at the feeling of her gripping and rippling along his shaft.

She squealed out in delight, bouncing beneath him with each of his motions. "Yes! Mmm, yes!" She hugged him tighter with all four hooves. "Yes!" There was so much more to it as a pony, and she was adoring every second of it. He was deep, far deeper than any human could ever get, and filling her so wonderfully with that stiff spear of his. Her walls were perfectly textured to rub along every inch of his tool. She shuddered both under and around him, welcoming him in to the root.

The motion wasn't as precise or practiced as his human form would have been, but instinct seemed to be working wonders in that regard. Each push into her depths was blindingly wonderful for them both. He leaned his head down to touch his nose to hers, even as his hips kept a steady pace. His tail wagged shudderingly with each push into her, slapping his equine balls against her.

Bella made soft little huffs with each push into her depths, purring gently as she met his eyes. "Stallion. Mine." She pressed her hooves into his back, gripping at him and keeping him there.

"Mine," grumped RC. "At least say he's ours!"

Not that Brad was paying her much mind, rocking deeper and deeper until a powerful twitch ran through him. He could feel it, bursting free of him with all the force he could have ever asked for. His shaft throbbed with its own desires, unloading directly into Bella's accepting depths. She giggled and gasped, holding him tighter with each squirt from him.

Pleasure blinded him a moment, fading with each rapid thump of his heart. He sagged and fell against her, huffing for breath with a wheezing laugh. "That... was amazing."

Bella cuddled him close. "Yes! My stallion!" She kicked a hoof about excitedly, not letting him go in the slightest.

Twilight sat at the edge of the bed, watching them. "Fascinating. Bella, how do you feel?"

Bella wriggled about on the bed. "Like I want to do it again."

RC made a disgusted noise. "With me, and with better technique. Here, stud, let me show you how it's done." She stuck out her tongue. "You had your turn. Time for you to be nice."

"Fine." Bella rolled her eyes before going in for a smooch with Brad. "I love you so much."

Brad pulled back, still a little dizzy if smiling. "Love you too." He slid off of her, turning over onto his back. He flopped about with his wings outstretched.

RC didn't hesitate in the slightest. She mounted up on top of him and shoved into place. She sank back on his shaft, not giving it time to soften. With a few good bounces, she had him well and firmly back inside her. She made short motions, pushing and pulling against him as she did her best to polish his cannon with her silken depths. "Mmm, that's the stuff. You, mm, have a wonderful pony cock. Use it! Plow me!"

Bella giggled and crawled over next to Brad, dropping her head onto his shoulder. "Yeah, do it! Ravage her!"

Brad wasn't exactly moving much beyond his hips, which were swaying in time with RC's motions. His haze was clearing up rapidly, getting back into the renewed passion of rutting. "You're not, mmm, in season."

"And?" RC stuck out her tongue. "Like humans only fuck during their cycles. Harder, mmm, harder! That's better. Yes!" She panted, nostrils flaring as she let her head fall back. "It's all about pleasing my stallion. There's no difference for me between seasons. Your stallion cock is so, so good." She beat her own wings in energetic flaps. "And me too, not gonna lie. Being drilled by you, rating pretty high on the fun scale."

Bella wiggled up against Brad's other side, head on his chest. "Liar. She loves you. Not going to lie about that either. She'd take you away from me if she could."

RC pawed at Bella. "Hey! Look, oh Celestia, we're all wives, right? Sorry, mmf, for fighting." She rocked against him firmly, pushing him deeper. "We can share him."

Twilight tapped a hoof on the floor. "Yes, I do agree with that. We are all married. You need to learn to trust each other more."

"Trust." Bella leaned up to touch noses with Brad. "I'm sorry."

Brad laughed, rubbing his nose to hers. "You still have that spicy smell, and it's making me, nng." He grabbed RC by the hips, driving into her with increasing fury. "Want you again."

Bella laughed gently. "Oh yes. It will take time for that to go away. Several days, in fact. Get used to it. And, um." She touched noses to him again, rubbing over him and getting close. "For now, make RC happy. I know you know how."

RC let out a gentle giggle. "Lies! He knows how to make us all happy. Just look at him, wings spread and cock buried inside me. If that isn't making me happy, I don't know what is." She suddenly howled, body trembling as she hit her peak. Her inner walls fluttered around him, drawing on him greedily. Her slick passage brought him off with her, gushing once more. She locked hooves with him, shaking atop him as he throbbed within her.

Brad groaned as he pumped thick gushes of his pony seed into her. He twitched a little with each, shivering in time to her own spasms. He watched as she sank against him, the two panting and quivering together.

"N-now I'm happy." RC pulled away from him, sliding off to one side. "So, uh, glad we're all married and all that."

Twilight bonked RC gently. "Don't say that like you're only here to be rutted." She rolled her eyes. "Brad, you have many wonderful qualities that have little to do with your bedroom performance."

Brad coughed into his hoof. "Thanks, I guess?"

Bella touched noses with him, purring as she rubbed against him. "All three of us care about you deeply, but yes, your stallion cock is rather fun." She grinned with newfound pleasure, including the power to smile like that. "Thank you, for sharing this with me." She hopped up to her hooves on the bed. "Being a pony is so fun!"

Brad nodded slowly, wings drooping. "It really is." He moved to the edge of the bed and stretched out his limbs. "Twi? When I change back, am I going to change back to human or stallion?"

Twilight opened her mouth to spit out an answer that looked obvious, until it didn't. "Oh. Oh, we hadn't considered that." She danced in place. "I hope you can return to being a human." She tensed, teeth clenched. "But there's only one way to find out."

"Huh?" Brad fluttered his wings. "And how is that?"

Twilight smiled nervously. "We have to try it." She licked over her lips. "Don't worry, I'll be right here with you." She pulled out the statue. "We all will be."

5 - Crossing Rainbow Bridges 20b

Brad trailed his hoof along Twilight's horn. "Where'd Bella wander to? She's usually around for snuggles."

Twilight was carefully inspecting every part of his body. "She decided to explore Ponyville. Said she wanted to introduce herself as a pony instead of a horse."

"Fair." Brad tensed up, wings going stiff behind him. "Wait. Does that mean I have to?"

RC thumped against his other side. "You are new to the whole pony thing. We aren't humans. We put this stuff out there nice and clear."

Twilight darkened, her face heating up with a blush. "You, um, really didn't notice?" Brad's clueless face was hint enough. "We are in estrus." She lifted an ear at Brad. "Unlike an animal, we are sapient, and can decide what to do about it, and ourselves. It does increase our libido all the same. Fortunately, or unfortunately, we have a specific partner already at hoof for such things."

Brad twitched an ear back and forth. "I think I remember that being explained. Huh. Wow, you do smell good." He took a deep breath, sighing gently as he rubbed along Twilight's flank, just to nuzzle RC, snout to snout. "Both of you. Is that what I'm smelling?"

RC reached out with her hoof to lift his chin up. "Yeah. It is. And we're going to get a lot worse before it's over." She gave him a predatory look, licking over her lips. "Though our sweet stallion can take care of us." She turned away, tail flipping upwards. "In a way only a stallion can."

Brad's head was already spinning, but he followed his instincts, pressing in close. The aroma had been there all along, and he had been responding as expected. His wings were spread, and he was pressing right in against her with a growing firmness. He squeaked as he felt something grip him down there.

Twilight's horn was glowing as she made a stroking gesture, her magic following along. "I'll help." As promised, she guided him towards her waiting entrance. "We both want a turn, maybe a few, tonight."

Brad didn't feel like arguing, letting the magic guide him. He sank into her depths with ease, the mare's body accepting him entirely. The motions were nothing like his old hips, but the sensations were amazing all the same. Her body was drenched on the inside, making each movement a moment for both to shudder and groan. "Rainbow..."

RC whickered, a gentle laugh. "That's good, stud. Keep going."

Brad huffed softly, pushing deep into her depths, pressing firmly up against her. Her wings fluttered, the mare's head lolling to one side. He spread his in response, finding their mutual motions could help smooth the process as he rocked into her. His balls felt full and tense, eager for the task. "W-wait, if you're, oh, what if you end up with a foal?" He was quite sure this was going to lead there.

RC rolled back against him, panting lightly as he filled and emptied her with each thrust. "Good! I'm ready. This family is ready to grow." She kneaded at the bedding with her hooves. "I won't, mmm, let Bella race ahead of us."

Brad gave a good thrust that took them both by surprise. RC shuddered, a short whine escaping her. He could feel her body gripping at him, holding him in tight as if she intended to milk him then and there. He couldn't hold back an instant longer. With a firm push, he shoved himself deep within and let go, erupting into her depths. The mare's eyes rolled as he throbbed into her, seed splashing against her walls with enough force to make her twitch around him.

Twilight gently stroked either of their sides. "Mmm, that looked proper. Now, Brad, you still have more to do, and I imagine you're a little out of breath too. Why don't we take a break?" She leaned in and gently kissed Brad on the neck. "I'll be waiting for you."

Brad panted softly and pulled back, slowly slipping free of Rainbow with a low pop and dribble. He fell back onto his haunches, then flopped to his side. "Damn you mares," he laughed out. His mild complaint died entirely when Twilight when in for hugs. He wrapped his hooves around her, pulling her against him. They rolled a little, coming to a rest with her on top.

"Hello," she whispered, pressing in to nuzzle against his neck. "As a unicorn, I have a few other tricks I fully intend to utilize." She grinned at him, her horn glowing. She lifted into the air, levitated by magic alone. She floated down atop him, easing onto his shaft. She pushed until they were one, letting out a gentle sigh as she sank all the way down to the base. "I will stay on top, if you please."

Brad shuddered and nodded, holding her with his hooves as she started to move. Her body was just as slick as RC's had been, and yet it felt like a different kind of riding. Being forced to let her do the majority of the movement was different, but quite pleasant, and relaxing after the last round. He spread his legs and wings to either side. "You can use me as much as you like." His head spun a little. The scents of them both were getting stronger.

A soft squeeze made him jump as something groped his filling orbs. He could see her horn glowing, giving a hint as to who was responsible. That glow extended up along her belly, then down beneath her, clutching at him gently. It was almost as if there were a second mare atop him, encouraging his growth. The sensation of being touched there even as he plunged into Twilight's hot depths was new and entirely unexpected.

Brad groaned, holding Twilight closer. She was moving slowly but steadily, each motion sending another jolt through him. His senses were on overdrive, smelling more of her scent, tasting her tongue as they kissed, feeling everything all at once. "Y-you want a foal too?"

"I don't want to be left out." She huffed gently. "It is, perhaps, a foalish reason, but you have three wives, and two of them are moving to have a foal. I don't want to be the only one not experiencing this." Her eyes glazed with desire as she ground against him. Her inner walls rippled and shivered along him, pulling at his flesh. It felt like she was stroking him all over inside, even though she was doing very little, at least physically. Her horn shimmered as her magic worked at him, teasing him constantly. "As your princess, I command that you inseminate me."

Brad blinked, confused a moment. "This isn't, mmmf, arti—" As if in complaint at his nerdy speech, tension exploded and released through him, pumping into her depths and filling her up. He could feel her body tensing and relaxing around him with her own peak. They came as one, bodies working to make it last as long as they could, pushing to the limits of their pleasure.

He fell back, twice as fatigued from the second burst. "That... that was even better." He wheezed softly for air, coming down from his peak.

Twilight hummed gently, nuzzling him. "I love you too, and yes, it was." She curled a hoof to her chin. "But I may be biased. I could only distantly feel the passion and love you two were sharing with one another. It was intoxicating, but nothing like the actual thing."

"Tell me about it." RC was watching the two, wings flapping gently. "That was incredible to watch. My turn next time?"

Twilight smiled and leaned back against Brad's chest. "Yes, but give him some time to recover." She reached over and stroked over his balls. "I'm afraid that these are empty at the moment, and he's already tired. We have all night, so we can take our time."

Brad nodded. "Yeah. That would be easier for my poor body."

As Twilight promised, they took their time with him. With his own mind starting to understand more of how it was to be a stallion. That didn't make the look RC was giving any less concerning. "You have something in mind?"

"You bet I do." She flapped her wings with a grin. "Something only pegasi, and I guess alicorns, can do."

Brad leaned in close. "But Twilight—"

"—Is already asleep." She nudged at Brad, pushing him away from Twilight, who was indeed snoring gently. "Come on, we don't want to wake her either."

Brad moved over with RC, letting her push him into the corner of the bed. "Alright?" He blinked at her. "What are you planning, anyway?"

RC nuzzled up against him. "Follow me." She led with a lively trot from the library. "We pegasi have a specific set of talents. Flying is involved in most of them."

Brad blinked. "Wait. How does flying—"

"Quiet, stallion. I am in charge, and I'm saying it's time to fly." She spread her wings and leaped into the sky.

Brad took a deep breath and followed, finding his wings doing the work for him. It was like flying, with more third dimensional action. It still amazed him how much he was getting a grasp on it.

RC flew in close to him, brushing his side with her hooves. "Now, two choices. We do it in the air, which involves a lot more skill, or we find a comfy cloud."

"Cloud please?" Brad wasn't sure about his abilities yet. "I'd hate to fall out of a rut."

RC laughed gently. "You would be fine, but I get your meaning." She rolled her eyes. "But I will hold this against you, coward."

Brad huffed softly. "Yes, I'm afraid of doing it wrong."

RC shook her head. "Fear is not what makes a great flier." She found a good spot and dropped, landing with a gentle bounce on a nearby cloud. "Nice, soft, and private." She turned around on the cloud with a nod. "Perfect for making more pegasi." She laid herself on it, tail flipping high. "What are you waiting for?"

Brad dropped heavily to the cloud's surface, sinking in slightly. "I was thinking." He walked up to her and nosed against her exposed privates. "I've never been a dad before, and now I'll be three at once?"

"And I never was a mom before. We're all learning." She gently smacked him with her tail. "More rutting. Less talking."

Brad snorted and took her with one smooth move. His hips moved with a lot more sureness this time. It didn't hurt that she was more than ready to take it, her body slick around him. They met belly to belly, rocking against one another side by side on the soft embrace of the cloud. Their motions sent ripples through the vapor.

He held her close, his motions growing stronger. Having done this twice before, he was learning fast how to make it work for him, and for her too. The two called out, knowing nothing but a passing bird was likely to hear their cries.

Brad's wings fluttered behind him as he thrust harder, his balls tensing once more with their duty. "R-RC!" He let himself go, pounding into her as he exploded. His body spasmed as he held himself there, pumping thick gouts of stallionhood into her.

She wrapped her wings around him, laughing as she nuzzled in close. "You have a hair trigger. I'm guessing it's being a new stallion, not at all used to being around ready mares."

Brad grumbled softly. "I would argue, but the evidence is a little stacked against me."

RC giggled lightly. She pulled back, letting his spent stallionhood flop free. It was a clear night out, and the moon was full out here, away from the lights of Ponyville. They were alone with nothing but the moonlight and the soft bed of cloud beneath them.

RC settled in against him, wings closing down. "That was unfair of me, maybe, a little. You were already tired." She kissed around his ear. "Thank you for putting up with me."

Brad closed his eyes, nuzzling in close. "It was a pleasure."

She hugged him tighter as they both drifted into sleep.

Author's Note

Continuing this, the mares find another use for Brad as a stallion. Bella may have beat them a little, but that won't stop them.
