With a light clop, Shining poked his head into the room. "The guards are looking edgy." He slipped inside properly, knocking the door shut with a sway of his hips. "Do they have a good reason to be?"
Cadance glowed brightly, her magic tying her to Umbra. There was no time for delays, only action. Their link grew fatter by the moment, their thoughts turning towards one another, but Cadance was working other magic through that crystal thread. "I will be what you need, tonight," she intoned dangerously.
Shining blinked. "O-oh... Um, how can I... help?"
"You are married to us, silly thing." She sounded distracted, working powerful magic.
[start clop]
She surrendered her very form to the needs and wants of Umbra. Her lines melted, becoming stouter, stronger, and a bit pointier in places. She let out a shout as she thrust her hips forward, a great equine member jutted out, newly formed and pulsing with new vitality.
Shining blushed at the sight. "My little monsters," he sang in the tune of the show he didn't know about. With a smile, he went to Umbra, gently nuzzling with her. "How are you feeling?"
"Excited." Umbra shivered softly. She couldn't take her eyes off Cadance and all she was promising without further words required. "Distracted? Excited..." A new scent was in the air. She was putting out all the signals that she was ready for what Cadance was offering. All her doubts, forgotten. There was only room for Cadance, with a teeny tiny slice being given to Shining.
Cadance sauntered closer, just as fixated on Umbra as Umbra was in kind. "I'm going to show you just how loved you are. Our love will be so complete, it'll become a living thing, a pony for us both to adore, forever."
Umbra suddenly went in to touch her nose to Shining's cheek. "I love you."
Shining blinked in clear surprise. "I thought..."
"I don't care." Umbra shook her rump in Cadance's direction. "We know what we want... But you don't." She took a moment, just panting heavily. "Damn her magic..." Love was washing over her overwhelmingly. "I love it, and you, and her... Don't go."
"That's my Umbra." Cadance nuzzled slowly over Umbra's rump, feeling those powerful leg muscles on either side. "Thinking of you even right now... When her mind's on something else entirely. This is Umbra at her best." She nipped at one taught slab of muscles, making them twitch with an excited neigh. "Staring down impossible odds with grim determination."
That Cadance still sounded like the female she still was, despite the other changes, only seemed to turn on Umbra more. She licked those fluttering lips, winking as they were in clear sign that Umbra was quite ready. "Shining, I will want your help. You know how stallions... work. Make sure I do this properly."
"Huh? Sure!" He circled around Umbra, blushing at the thought of what was to come. "You've, uh, been part of this... You know half of it at least."
"At least half." Cadance reared up, her magic pulling Umbra back even as she slid forward. "But not the other half."
Shining could see the first problem. Cadance would be thrusting for some time before finding the mark, being quite new at having that particular part. He hesitated a moment. He'd never touched another stallion there... But it wasn't a stallion. It was his Cadance. He shook away that hesitation and grabbed her, guiding her to her target.
Cadance tensed with a shiver. "Oooo! That... feels nice. Is that what it's like when you're grabbed there? You... never told me... Someone's getting held there more often." Cadance pressed against the grasp of her husband. "Ready?"
"Ready," he called, sure she was aimed for the task. "Go on."
Cadance didn't shove in, instead working gently forward, letting their parts kiss together and only slowly pierce past those fluttering lips that grasped and pulled at her. "Who's a good girl?" she purred at Umbra beneath her, hugging her firmly from above. "Best part, hm... If it doesn't stick, we'll have to keep..." She pressed an inch. "On..." She drew back but thrust further, working her way inside. "Trying..."
That sounded like the most wonderful problem to have. She was a mare! She was being the most mare one could be, pinned beneath a loved stallion, the two with thoughts of quickened life within her. It was, at the primordial, the most basic essence of being a mare. No slight on the poor mares that couldn't, or maybe just didn't want to do that, but she did, and she was ready!
Cadance pulled Umbra with her hooves, coming in as close as she could and sinking to completion, the two as firmly together as they could be. "You are just as lovely inside as you are on the outside." She nuzzled into the wafting mane of her mare, just to be held in kind by it. "I forget that part." She drew a few inches back to smoothly saw forward. "So... eager to join Luna and Celestia, were you? The animate mane club..."
Shining ran his arcane grasp over the two in their mating dance, petting and stroking them gently. "You two are doing great," he encouraged, perhaps sounding more like an eager coach. "Um, one little thing."
Umbra twitched an ear towards him, so much of her distracted by the wonderful motions being made against her. "What's... that?"
"After this." He worried his hooves together. "No reason we can't do this for fun."
Umbra siezed, just to burst into laughter. "Oh, my... god..." She shook her head firmly. "Silly horse. Yes, of course. I'll torment you after Cadance finishes ravishing a foal into me."
"Wait your turn," gently sang Cadance between her firm pushes. "It's coming, promise... We both happen to like what you have. You won't be bored for long, I assure." She grit her teeth against the building tension. "I feel... close... Mmm, damn new... parts..." She tried to hold it back, to keep it going, but those were entirely foreign sensations, at least for her to experience firsthoof. She was losing grip quickly. "It's coming."
"No, you are," chuckled out Umbra before a moan drove her joke from her. But then, she felt it. She'd felt it before, and yet, it seemed new. Warmth spreading through her insides, but it wasn't just that. She could imagine Cadance atop her, completed in some new way, hear their gasping moan, their desperate clutching. Umbra could imagine that spark, the fire that would catch inside her and start a new thing. The fantasy rolled over her, twitching and squeaking as she fell headfirst into female completion.
But it wasn't the end of their session, soft kisses and nuzzles making her twitch at the new sensations. "W-wha..." She craked open an eye to see Shining nuzzling against her, working deeper into her pelt. "Lovely boy."
"He is," Cadance sighed out, sliding back to her hooves. "But he isn't wrong. This isn't over." She bit at Umbra's rump. "You are more than a place to plant a seed! I won't let you start thinking that."
Umbra started with a jerk. "What?" But the question came quickly as the two diarchs pressed against her front front and back, soft kisses and gentle nuzzles drawing the warmth from her. "This... This is..." Kinda great? That felt lame. There had to be a better way to phrase that. She stepped from hoof to hoof slowly as they explored her. "I..."
Shining stood up to kiss her under the chin. "I love you."
So flat, so direct. Umbra felt as if she had been slapped with it. "I..." She grabbed him, hoof to either of his cheeks. "I'm a mess, but I'm learning to like this, a lot..." She pressed her nose to his, hooves falling. "How can I return the favor?"
"You can stop thinking about that." Cadance nipped at the base of Umbra's tail, at her dock. "You can enjoy what we're doing and make little sounds. Each gasp we get from you tells us we're doing it right."
Umbra delivered a shallow gasp as if demanded. "Unfair!" But she was caught between two loving ponies. "Un... fair." She half-lid her eyes, tail swaying just over Cadance's snout, to jump as a wet tongue pressed against her sensitive doughnut. "Ee," she squeaked, blushing anew. "I want a turn!" Her horn glowed as she took firm hold of Shining across his form.
"A turn at what, exactly?" He didn't resist the grasp, calming to let her speak. "This is about all of us, so go ahead."
"Now... Not entirely true." She reached up a hind hoof to poke at Cadance. "This one here has dibs on where the foals come from until we know it stuck. But there is more than one way to make a male happy."
Shining flipped an ear back. "Is that... so? What sort of ways?"
"As if you don't know." Umbra tugged him closer, biting into his shoulder with her sharp umbrum teeth. "Like it or not, besides being close to the ones you like, males have this big stick that they love playing with."
Cadance burst into giggles. "One of their favorite things." She moved up along Umbra, rubbing against her. "We don't want him to think we don't like it too."
"Love it." Umbra licked over her lips. "Willing to prove it."
"Prove it... how?" Shining was tense with eagerness, but still, other than his swaying tail behind him.
Umbra's horn glowed all the brighter as she forced him to kneel and slowly roll over. "You are mine, right now. Little sun defender. You can't keep the princess of shadows at bay." She loomed over him. "Just a matter of whose tongue is going where, really..."
Shining grew brighter as the naughty speak became more blunt. "I thought it was my turn."
"I did say that," sighed Umbra in defeat. "Promises are promises." She sank, not putting her honeypot near him, instead where she could coil down and nudge in, nuzzling the side of his boated sheath and its heavy staff. "I never really had time to just... enjoy this. Only what cadance shared, and that isn't the same thing."
Shining ran his hooves across Umbra's undercarriage, shivering at the touches. "No... no it isn't... Um, speaking of... Mmm, that..." His member twitched hard, a lone spurt of building fluid emerging. "You will be a mom for the first time."
"Thanks for the reminder." She nipped his staff carefully, engulfing it between her lips and drawing it in. There wasn't time for more words, nursing as she was with little lewd noises of suction. It was at that time that Umbra learned what it was to have an equine member across her tongue, flat ended and just faintly swollen towards the end with its excitement. It wasn't like a human tool, but it was a fine one, and it belong to a pony she liked. She purred into it, making its owner squirm as she worked deeper into it, using the space her snout provided to take it in easily as her tongue curled and teased at the sensitive length.
"I like what I see..." Cadance petted across the two with softly applied hooves. "Such love..." Her horn glowed as she focused on the thread between them, growing it rapidly until the two had little room for her, but she had done it on purpose, not being upset or surprised by it. "Drink it in..."
The pleasure she was bringing was, itself, becoming a point of delight. Just knowing what wonders she was bringing to the pony that meant so much made it rebound on her and it was her everything. She grasped with her magic, playing with his heavy seed-filled orbs. Just playing with them made her think of his masculine traits, so strong, defensive, stout... He was also a nerd, but she liked that part too. She worked them in time with her slow rocking motions, sinking him in and across her tongue. There was no room for words, just the adoring motions.
Umbra jumped in surprise at a new sensation. Shining couldn't quite reach her, all the way back there, but he found another spot that only mares hade. Stallions, unlike humans, had no teats. Mares did, and he gently licked and pulled at hers, making her squirm with louder groans with each motion. Their pleasure had formed a full loop, feeding into one another.
Free of her own distractions, Cadance focused on them, keeping their attentions turned on one another. "What is your favorite part of Shining Armor?"
Umbra's reply was muffled by the turgid length in her mouth, if it even was words. Few could hope to say. But she did know that Shining was tripping over the finish line. His shaft was swelling against her, preparing for that final moment. Umbra sealed her lips and pulled with her tongue, roughly emulating the loving embrace of a mare's passage as it reached its peak stiffness and exploded, each surge of fluid flowing up the pole to splash across her waiting tongue.
She swallowed as quickly as she could, gulping it down like the protein shake it was. Just as she thought she was reaching her limit, it petered to a stop, leaving her with the softening example of his passion. She smooched it, nuzzling back away from it. "Damned stallion... Thank you."
"You're welcome," he got out between gulps for air. "Um..." He looked over at the smiling Cadance, trying to return the gesture with only middling success. "You alright?"
"Watching that was fun." She rose to her hooves. "I just feel a little awkward."
[end clop]
Cadance colored in a subtly different way, not of fatigue or working herself up. "I... didn't expect that to end so swiftly."
Shining snorted at that. "Easy to say, not to do." He grabbed a towel and got to wiping down both of them. "How do you feel, Umbra? Too short?"
"N-no?" The whole focus on Cadance had faded entirely. It was fading during the act, with the distraction the act itself provided. "No. I feel... pretty damned fine..." Umbra shook herself to the limit allowed in that stance. "Um... Let's clean up, then we can talk and maybe sleep and do other things married people do at night?"
"That sounds lovely." Cadance smooched Umbra on the back of the head and slipped to the floor carefully. "Congratulations."
Umbra perked an ear. "What am I being congratulated for?"
"I could be wrong." Cadance waved a hoof over Umbra's form, her own returned to its usual female lines. "But you couldn't be before. Now you are one. You are a pony that is making other ponies. Congratulations."
"I'm a breeder," laughed out Umbra, realizing what Cadance was getting at. "Oh no..." She accepted a glass Shining was offering and swigged half of it in a hurry. "Oh, thank you." She went for a kiss and got one, sharing with Shining. "You were very polite and helpful. I know that didn't have a lot for you, which makes it even better."
"Hey." Shining tapped his horn against Umbra's. "Two ponies I happen to like a lot were sharing a special moment. There was plenty for me." He sat and crossed his arms. "Besides, for one, you did give me something, and we just went over it. Not like there won't be other things later. Playing support one time won't kill me." He threw the towel into the waiting hamper. "Bath?"
Cadance pricked at that. "Excellent idea. Umbra, you haven't experienced the joy of having a bath attached to your bedroom. Come along, time to cleanse ourselves." She led the short way to the waiting bath. "Just hop in and enjoy yourself. No awkward steps down a hallway or three."
Umbra sank into the water, placing her tiara aside. Her mane went limp without that. With soft splashes, two others joined her. "Oh, thought." She turned in the water, enjoying its warmth. "Was the rest of my family told about this move?"
Shining thrust a hoof out of the water. "I made sure they knew." His horn glowed as he grabbed a bottle of shampoo. "Now, how about we get to the lather." Both mares giggled, but didn't fight the offer for a good, clean, time.
The next day, Umbra sat in the throneroom. She nodded or shook her head at each request that came to her. She did her best to be an impartial judge, to the limit of such things, to render fair rulings on each that came before her. It seemed to be going well, and it got Cadance a day to herself. Wins all around.
It was also kinda nice, being a queen. Er, princess. Ponies and their queenly aversions... "Next!"
The room grew darker as a familiar figure strode in with a smirk. "We meet again."
Umbra's eyes narrowed as she hopped to her hooves. "Jerk!"
It was the jerk. He had a name, Sombra, if one forgot. "This kingdom was mine, and shall be again. I've been restored to my full power, and your pathetic imitation is no match for it."
Umbra flipped an ear back, wishing a moment she hadn't sent Starlight on home. A helper to blast the jerk woulda been really nice. "I'm not going to just let you do that."
"I wasn't asking." With a toss of his horn, the eyes of several guards went from wary to blank, their will to fight beaten from them in a snap. "I'm taking them, and you. Where's that pink one?"
"You won't need to see her." That was a reminder. Umbra focused on the image of Sombra in all his malicious glory. She shared it across her link, trying to broadcast it as hard as she could. Where he stood, how he stood, and the words he was saying. They needed to know that. "You won't make it past this room." With a great stomp, she summoned a wall of crystals behind him. "You didn't come here to conquer me, you just surrendered to me."
"I think not." He waved at the crystals as they dissolved and shattered. "I was playing with crystals before you even existed. You had me at a disadvantage, wounded and weak as I was. No longer! Feeble shade, bow to your superior and I may allow you to breathe for another day."
Umbra squared her shoulders. "No." A shadow bolt few at her and she dodged Sombra's attack, melting into the ground a moment to re-emerge a few feet away. "No."
"Not a question," sang Sombra as he slid heavy helmets onto the subdued guards. "I am informing you of the reality of things. Capture her." They weren't the only ones, other ponies marching in from outside, all wearing the same ghastly helmets with glowing eyes as they headed straight for Umbra.
"Flash..." She recognized one of them right away. Fighting her former friends and allies felt... "I'll be back." She sent the image of her departing to the others, but did just that, fleeing the scene rather than press the fight.
