Silver rose to his full height before Twilight, overcoming her by a few precious inches. Stallions grew larger, faster, than mares, and despite his still young form, he enjoyed a height advantage. She smiled up at him, looking both nervous and anxious. He leaned in and gently nipped along her snout. "It's been too long. Has anyone reminded you just how pretty you are?"
Twilight leaned her head back as she challenged. "What kind of pretty?"
What kind of pretty? Well... "You are beautiful in your majestic strength. You have the raw power to dominate what is around you, and the grace to not do that in most situations. You have the adorable awkwardness of a scholar, who's knowledge and insight draws me just as fiercely. You have the overwhelming aura of purpose, surrounded in a field of destiny that cannot be denied. I am yours because it was decided, and I wouldn't want it any other way."
Twilight colored more and more as Silver spoke. When he reached the end, her wings were extended, stiff and wide. "Are you just saying that?"
Silver brought his wings forward to hold Twilight gently. "I said something a long time ago. I would allow myself to be laid bare before you, my lovely scientist. My pretty scholar. I am your subject, your stallion. I am yours."
Fast Change rolled her eyes. "You're supposed to be dominating her, you goof, not setting yourself up to be dominated."
Twilight gave Fast a sour look before she smiled at me. "Lay down." Silver slowly sank to his belly. She made a twirling motion and he slowly rolled with her motion until he was on his back. She giggled a little, not used to the idea of having that sort of power. Even acting like a princess still got to her at times and made her feel awkward, but here was this stallion, proven and even bloodied, doing as she asked with a smile. "Now then, it's time I got my answers."
She trotted around Silver in an almost-walk with how slow it was. "Tell me what you did with Celestia? I want to hear all of it. Spare no detail." She suddenly leaned over Silver. "Did you and she, you know... did you?"
Silver nodded and suddenly Twilight's magic wrapped around his sheath, stroking along it. "Go on," she beckoned as she teased him. "Details, all of them."
Being wrapped in Twilight's magic always tingled a little, having it focused on his sheath made him pant a little as he quickly returned to full hardness beneath her. "I tried to give her a foal, and almost killed myself in the attempt."
Twilight recoiled. "What? How?"
Silver reached a hoof and gently ran it over her snout. "To quicken the womb of a true alicorn is quite a challenge, possibly one that grows in magnitude with age. She is ancient and powerful, and I wasn't stallion enough to fill her, and almost paid the price for it."
Twilight glanced back at her barrel and frowned at Silver. "And yet... we have a foal. Tell me, how many foals have you left scattered around in your journeys?" She pulled and stroked gently with her purple-pink magic. "Did you leave a swollen mare in every port?"
Silver grunted with pleasure and bucked his hips. Thin streams of preseed ran down his member as his excitement grew. "It's not... It's not meant to be. I've sampled mares, but my seed isn't... It isn't right. Maybe it's the... That I'm not what I seem to be."
Twilight perked her ears curiously. "You're infertile? But you gave Night Watch a foal." She pulled at his flared head while rubbing just under it. "Explain."
Rough Tumble raised a hoof and looked ready to approach, but Fast Change threw out a leg in front of him. "Let them."
Silver squirmed under her teasing. She had complete control over very sensitive parts of his anatomy, but he knew he could throw it off if he really wanted to, but he didn't. "I have theories. I gave her a foal before I was an alicorn, before things got as complicated as they are."
Twilight tickled downwards along that member and grasped his balls in her magic, massaging and gently working over them as she watched his face. "You know, you weren't the only one doing irresponsible things... learning things... Being changed."
Silver perked his ears. "What happened?" He grunted as Twilight began stroking him at the same time as playing with his heavy, jeweled, balls. "Ooo, whatever it was, please... I'm here for you."
Twilight's face fell a little. "Is that your 'forgive everything' mentality showing again? You shouldn't forgive me for this." She squeezed painfully and Silver squeaked. "It's not something small."
Silver threw off her magic suddenly and rolled up onto his belly, facing her. "Twilight, whatever it is, tell me. Let me make my own decisions."
Twilight's eyes fell a quiet moment before she nodded. "Very well... Do you remember the experiment I ran, trying to reach your world?"
"It didn't work, what about it?" asked Silver curiously.
Twilight slowly rolled a hoof. "Only sort of. I created a corruption. I destroyed harmony in a very real way, and that corruption came to say hello." Silver sat up sharply and Twilight pushed him down with her magic, settling him back on his belly. "They weren't hostile. They were very kind, even, if confused, and badly warped by my failure. I... I caught some of it, and it overwhelmed me."
Silver looked Twilight over, but she looked entirely fine. "What happened?"
Twilight let out a soft sigh and settled to her own belly. "They burned it out of me. I... hurt them, again, but they cured me. Please don't be angry at them, they really did everything they could to put it to right."
Silver nodded stiffly. "Alright, so... why are you upset? If it's fixed, then what's the harm?"
Twilight pointed downwards with a hoof. "I was pregnant with our foal at the time."
Silver cringed. "He was... fixed too, right? He looked alright."
Twilight leaned forward and flopped, exposing her neck to Silver. "I think so, but how can I be sure? My failure brought danger to him, that little life you trusted to me."
Silver felt the urge to tell her it was alright, that he forgave her, and that everything would be alright, but that wasn't what was wanted. He darted in and grabbed her by the throat, his jaws closing dangerously close to cutting off her air and crushing her windpipe. "Why?"
Twilight swallowed heavily around those intruding fangs as red blood stained her purple fur. "I... I was curious. I wanted to see your world, then I made a mistake, and... it all ran out of control! I'm so sorry!"
Silver drew back and ran a long tongue across her fresh wounds as his eyes lifted to Fast Change. "What do you think I should do with her? My little scholar put her nose in the wrong book and got a nasty burn for it."
Fast frowned a little. "Clearly, she needs to be reminded her actions have consequences."
Silver moved over Twilight, who was still belly-up. "For every action, there is a reaction. This is one of the basic laws of the universe, and cannot be denied. Even more immutable than the very force of destiny itself, my lovely little learner." He inched up and over her, pressing the flared tip of his member to her folds, making her gasp at its girthy presence against her. "You've set this new action in motion. We'll have to work together, as a herd, to counter it, but even that, you well know, will have its consequences. There's no escape, my lovely princess. We have been touched by your actions."
Fast leered softly. "Are you going to show her her mistake the stallion way? I didn't think you had that in you."
Silver shook his head. "That is exactly what she wants." He pulled back from her winking vulva and kissed her across an ear. "My cherished seeker of the unknown, I'm afraid you're getting it last, and I pray you use the time to consider yourself. I know you can do better."
Twilight looked shaken and confused. She slowly sat up and peered at him, then looked across to Fast and Tumble, who were both looking a little sheepish. Fast shrugged softly. "Sorry, he gets to call the punishment on this one."
Twilight struggled to her hooves. "But... Didn't you want?" She looked like she wanted to protest that she wanted it too, but decorum stopped her wagging tongue and she pawed at the ground. "If this... is what you feel is fair..." She licked over her lips. "I... I still want to know, everything."
Silver put a hoof on her nose, allowing the warmth of his earth pony magic to gently wash over her. "You always want to know everything, and it's one of your wonderful traits, but this time, you'll have to wait. That's part of the punishment."
Twilight trembled softly as the powerful magic ran through her snout and she crossed her eyes, looking at his hoof. "What is that? Please! Tell me." But Silver didn't oblige her. She squirmed and grunted and looked quite upset, but it was a good upset, so far Silver could see. She would be punished, and they would move on, together.
Fast moved over and bumped Silver, nose-to-nose. "Come on. Night Watch hasn't gotten her turn, and she deserves one. Poor girl's been so worried for you. Did you miss her?"
Silver quirked an ear. "Miss her? Of course I did! She is the closest I have to a first wife, officially, and I think about her all the time."
Fast nuzzled his cheek. "Then show it. I'll relieve her of duty and you two can go do whatever nature and love compels you, and it better be raunchy." She trotted out the door with her tail swaying.
Rough Tumble smiled nervously. "I'll help watch the foals. You go and have a good time."
Silver nuzzled Twilight, then Rough Tumble. "You're both good ponies, even if I do get angry sometimes." He turned and followed Fast quickly to the stairs, with Tumble following just behind. Twilight remained in the observatory for the moment. As they descended the stairs, Silver swiveled an ear towards Tumble. "We barely started our date. A quick bout, no matter how intense, is not a replacement for actually getting to know one another. A real date."
Tumble blushed gently. "Maybe we could go out to eat?"
Fast snickered softly. "He can take you out to eat when--"
"I use your tricks," cut in and finished Silver. Fast looked at him curiously. "Shapeshifting. If I go as another pony, we'll just be two colt cuddlers, enjoying our deviance, without royalty involved."
Fast snorted softly. "When did you learn shapeshifting spells? They're very complicated."
Silver shook his head. "I didn't, and I probably won't, but that won't stop me from casting by the numbers."
Fast burst into a giggling laugh. "If you don't know what you're doing, you're going to be one generic pony at best."
Tumble slid up alongside Silver. "I don't care what he goes as, so long as we're together."
Fast smiled. "Aw, that was sweet... I'll show you some spells, Silver, after you see to Night Watch."
