Celestia stalked towards her waiting room. The thought of the help that awaited her there made it more difficult to control her body's outward signals of readiness. It just wasn't seemly for a princess to let her nethers flap with more force than a panicked bird, so she kept them still, mostly. The occasional twitch was all the world had to see as she walked with all due composure.

She thought back to the courtroom. She hadn't expected Twilight to just announce her preference so strongly, so... firmly. It was quite shocking to hear. That was, perhaps, one of the reasons Celestia had agreed. "I must speak to her."

Her horn opened the door before her effortlessly, shrouded in the same golden light as her sun. Inside were her two potential companions. Troubleshoes was on his haunches on one of the pillows that were sized for herself or Luna. It fit him well. He raised a hoof and waved it sheepishly. "Good ta see ya, ma'am."

Celestia nodded at him as she closed the door behind herself. "Good to see you too... Troubleshoes, was it? Twilight. We have things to discuss."

Twilight cleared her throat as she thrust a hoof at a wall where her horn made a glowing picture, a diagram. "As you can see, copulation with me, or any number of other mes in this case, will result in a child with far greater magical potential." The graph had a long line with a smiling Twilight face on it. "My competition, the alternative, is an unknown for magical potential, but a quick bit of research shows no great magical abilities run in his family." She lowered her hoof to show the much smaller bar with Troubleshoe's moping face. "Why take chances? I am the sure bet. Breed with me and we'll make a foal that will rock Equestria."

Troubleshoes looked at the floating diagram a moment. "Well..." He licked over his lips, clearly considering his words. "If you pick me, Ah'll... rock you as hard as Miss Sparkle's promising your foal could do." He gave a firm nod, satisfied with his words. "This is about you. You deserve it."

Celestia sank down onto her own cushion, squirming a little at either's offers, for great magic, or pleasure. On one hoof, she did want a foal worthy of the position, on the other, magic was not the only measure of that. "Troubleshoes, tell me about your... strengths." Her wings fidgeted with a mind of their own. In that private room, she could let some of her control go.

He stood up on his cushion. "Well, ah'm strong." He reached forward for the table that rested between them all and easily hefted it up with sheer kinetic grip with his hooves, showing some mastery with that subtle talent of hoof magic. "Ah'm a performer too." He set the table back where it had come from, but the tilt had caused some parts of it to start sliding, and they didn't stop because the table was put down. A collection of cookies fell across Trouble's face with a clatter. He smiled at Celestia, an assortment of those cookies revealed laying across his teeth in a ridiculous display.

Celestia chuckled softly as her magic reached to free the stallion of the mess he had made. "I see..." She wanted both. Normally she would carefully consider the merits of either and make a choice, giving up the other, but that day would not be like the others. "I want both." Her eyes settled on Twilight. "You will assist me."

Twilight looked baffled, ears going askew as her head fell to the left a little. "How will that work, Celestia?"

Celestia pointed between Troubleshoe's hindlegs. "We will not require a clone of yours. I want you to enchant him, where it counts. I want you to enchant him so hard, well, his foals will feel it. When he breeds me, I want your magic to be part of it, and my child will have his strength and your magic." She licked over her lips, warming with the thought of it. "I want you both, and you will deliver it." It came out more forcefully than she had intended, but it was the truth and she didn't feel like blunting her words.

Twilight shivered softly, a little smile spreading on her face. "If you're sure, Princess?"

Celestia had told Twilight plenty of times to not call her a princess, but if it meant things moved forward. "Yes, proceed."

Twilight rose to her hooves, bowed low before Celestia, then turned to the somewhat nervous Troubleshoes. "Our princess has commanded it, and I have no intention of denying it. Will you accept it?" Her horn glowed softly with a promise. "Or will I have to hold you down? For her, I would do just that."

Troubleshoes shook his head quickly. "Now h-hold on! Will this hurt?"

"A little." Twilight stepped towards the larger stallion. "Only at first. Besides, you get to top the Princess Celestia. A little discomfort is a mild price to pay. You will be her consort, and I imagine she will treat you quite kindly. Consider this a mark of ascension, a rite of passage as it were." She spread her wings wide. "Do you think these came without pain? Growth hurts, but I think you will enjoy it in the end, oh so very much."

Celestia watched her former student with a raised brow. Her sudden aggression was interesting, and a little arousing. She had claimed to have no interest in breeding Celestia, but she was starting to doubt that was the entire truth. Twilight, dear Twilight, adored her. She was willing to much for her happiness. Celestia smiled gently. She did not deserve such devotion, but it warmed her heart to have it. Alas, other parts of her were competing with warmth. Rubbing her hind legs together, she looked to Troubleshoes. "Close your eyes and relax. Twilight is a caring pony. If you trust in her and allow her to work, she will do her best to make this a pleasant experience."

Troubleshoes looked between the two. "A-alright... Ah mean... yer both good ponies." He smiled, a nervous one. "'Sides, would be my luck, go ahead." He didn't close his eyes though. They remained focused on Twilight, watching her intently.

Twilight nodded primly and reached out for Troubleshoes. She rest a hoof on his furry testicles, gently rubbing over them. "Average, for your size, but we'll soon address that." Her hoof slid along underneath the orbs and lifted the uneven sack into the air. "Of course, your size is considerable." She weighed those seed factories as her horn began to glow brighter and brighter. "First, I will open the pathway my magic will flow."

"What way is--" His words cut off into a low groan as Twilight's magic grabbed hold of his member. It tingled all along his half-hard pole with the force of her arcane will. She was drawing it towards herself even as it pulsed with new blood, growing firmer and longer by the moment.

She opened her mouth as it drew close and kissed its flat tip, right over the hole that led where she wanted to go. Her tongue slipped free of her snout and delved into that sensitive passage, making Troubleshoes squirm with escalating sensation. Her magic flowed around her tongue, pressing down along the thick tube that his seed should have taken. It was spreading him out from the inside, pressing further and further. It was like Twilight was fucking him in a way no pony should have ever done so before.

The worst part, perhaps, was that it felt great! He put his forehooves on her shoulders, grunting with pleasure. Was this the pain that was promised? He would gladly take it!

Celestia watched the two with half-lid eyes. She was jealous of her former-student, being allowed to play with that enormous slab of equine meat before her. Part of her wanted to swat Twilight aside and take her rightful place, but she had more control than that, yes. Twilight was simply preparing him, for her... It would be all the better once it was done. she just had to have... patience. "I've waited this long," she barely breathed out to herself, calming herself a little.

Twilight's magic delved deeper as her mouth stretched to accept the crown of the mighty tool she held between her hooves carefully. A spurt of pre-fluid began forcing its way up, becoming mixed with her magic as it forced its way up with powerful contractions of Trouble's cock. Twilight closed her eyes as it escaped into her mouth in a powerful spurt of dimly glowing seed, splashing her tongue with the bitter brew of life. She swallowed it down, unwilling to release her grip as she worked.

Her probing will met the first barrier she knew had been coming. She had reached his prostate. With gentle exploration, she felt around the sensitive organ, seeking the next passage that would send her deeper into his masculine tools. Trouble squirmed, grunting out, "That... feels funny..." If that would be the height of discomfort, Twilight would considered the operation a success. She found the exit towards where the lemonade was made first, and skipped over that. She knew where her mouth was, so there was little use for that. The narrow little tube that ran down into his great balls came into her feel. She pressed down into it and knew she had arrived. The power of potential life thrummed around her as seed was already being prepared to spray.

Step 1. She clamped down on the whole thing, shutting down the process. Trouble let out a sudden howl of pain as his seed factories were put on forced pause.

Step 2. She let her influence spread over the entirety of his testicles, filling him through the line she had made through his stallion bits.

Celestia's tongue slipped free just a little as Trouble's balls began to glow softly with Twilight's magic. "Go on... make him full of your magic. Give it all... I want his balls to have your cutie mark."

Troubleshoes blushed, still recovering from that instant of sudden pain. The idea of having Twilight's stars on him in such a private area was a strange idea, but he had committed, and he was a pony of his word. "It'll still be mah foal, right?"

Twilight nodded as well as she could, sinking another inch of Trouble's pulsing member into her soft lips. The glow of her horn intensified with every passing moment. She was on step 3, saturation. She filled his balls with magic, pure magic, with no intent or will, unbridled and free. Much of it would escape, but she kept pushing. What escaped made a glow, but what was absorbed was more important. She could feel it being taken in. His balls were warming with all the energy, but the heat was not harming his virile seed, as they were taking it in as well. She could feel motion, tiny motion, wriggling against her magic as his little swimmers grew more numerous and more active. The very organs that produced them swelled with given power and the whole thing began to grow with every beat of either of their hearts. She lowered her hooves from his dick down to his balls, feeling them grow between them.

She was empowering his fertility and virility in the most direct way possible, and she enjoyed the feeling of power in it. She could feel her own power waning. She was powerful, even more powerful as an alicorn, but her stamina did have limits, and she was pushing as hard as she could to make his balls a new source of magic. She strained and began to snort for air through her nostrils, her mouth still sealed on his member. It was becoming work, true work, but she would not give up.

The discomfort of before was forgotten, wiped clear with the increasing sensations of utter virility. He felt like he could take on all the mares of Equestria, one after the other, without pause. He pulled Twilight closer with his hooves on her shoulders, his hind hooves squirming and fidgeting. He wanted to breed, to mount every mare in sight. He looked up and saw her. Celestia. He saw her with new eyes. There was a female that matched the intense sensation of utter masculinity he was feeling. He would top the sun.

"Just my luck," he practically growled out. With great balls that glowed with fierce purple light, he pushed Twilight back. She pulled free of his shaft with a wet pop, panting for breath. "Wait yer turn." He pointed to a corner. "Ah'll get to ya." The idea of letting a mare, any mare, escape without his attention had become entirely alien. "But first..." He strode towards the snorting Celestia. He could smell she wanted him as bad as he wanted her. Her eyes were glassy with desires she was surrendering to. She would be his, and he was ready.
