For better or worse, Silver was feeling more confident about himself than he had a week prior. Taking charge of situations had its advantages, and was a fair sight better than waiting for things to happen to him and react to it. Thinking on that, he looked aside to Celestia, who was eating breakfast quietly. "Are we expected in court soon?"
Celestia perked an ear at him. "Court begins at noon today. We have several more hours to ourselves to do as we please."
Silver nodded as he looked to Shei and Aila. "Go into town and fetch a silver tail bracelet, have it engraved 'The Sun Shines at Night in the Splendor of the Moon' and have a crescent moon put on both ends."
Shei raised a brow. "I could do that alone, master?"
"And yet my command remains."
Shei rose to her hooves with Aila, and the two departed, escorted by the guards. Silver called out to them. "See they travel safely. It would reflect poorly on yourselves and the pharaoh if they come to harm in your care." And then they were gone.
Celestia turned to face Silver. "You look like you have something on your mind."
"You." Silver rose up to his hooves. "I'm done waiting for you to attack."
Celestia smiled gently. "Are you now? What do you propose be done?"
Silver circled around the still-seated Celestia. "Attack first, of course. You are another challenge, my princess. A very large and majestic challenge, but one I will conquer, or be crushed by."
Celestia squirmed faintly, her flowing tail giving a light twitch in response, but she sat in her usual regal position. "Am I? Will you try to lay me low with some clever magic?"
Silver leaned in and nipped at one of her suns before nuzzling into it. Celestia went rigid. "I warned you. Have you made your peace?"
Silver nuzzled her tail aside even as it twitched as if to swat him aside. He buried his snout against her nethers and lapped across her heated vulva. "Stand up, unless you prefer going belly-to-belly."
Celestia's ears twitched softly as she rolled over. "As lovely as it is, my tail makes that position... awkward at times. If you are serious, then come, Prince."
Silver slid in on top of her, grinding his already rigid pole along her soft white fur. His fangs went for her throat. "You are mine, Princess of the Sun. Not in the same fashion as the girls, but mine nonetheless." He sank them into her and she tensed, breathing quickly beneath him. He didn't feed her emotions, instead he drew at her magic, tapping into that vast pool of solar magic. His entire body started to warm swiftly and he channeled it along with his own fury between his hind-legs. He began to swell, orbs growing with every loud pound of his own heart. He would succeed, or possibly kill himself, but not for lack of effort.
With the intense magic back there, he couldn't hold back any further. He moved himself into position and sunk into her without further preamble, sinking into the burning furnace of Celestia's silken passage. He had to break his connection to her, drawing back with a loud hissing gasp of air. Being in her was a new pleasure, and a new pain. She contracted tight around him, milking at him with enough force that he felt he could simply remain attached to her and reach climax if he desired, but he didn't want that. He gripped around her and pulled back before thrusting in powerfully, starting to build a rapid tempo into her resisting body. Her tunnel fought his every move, but her soft gasps and moans said that she was enjoying it despite the fierce battle that her body was presenting.
Even as he ran his tongue across her neck, he focused on building his own magic to a fever pitch. The room swayed and rocked, dizzy with a combination of solar and personal magic raising his temperature dangerously, but he wasn't ready to give up yet. For better or worse, climax crashed down upon him swiftly, and his mighty balls jumped, forcing the seed down his cannon. Suddenly Celestia squeezed tight enough to stop the flow. "Last chance."
Silver grunted in frustration and moved in to kiss Celestia, locking snouts in a passionate exchange. The pressure lessened and he fired into her like a hose, spraying down the burning flame that had tormented her. He felt the suction, pulling him in to the hilt in her and nursing eagerly at the energy held in his swollen balls, though they seemed to be contracting back towards their normal size as she pulled and pulled at his masculine energy without stop. It was debilitatingly wonderful. If he just let go, he could die a happy stallion, but he didn't want to give up yet. He kept the fever pitch high and funneled the magic as quickly as his body could produce it, feeling like he was running a frantic chase with a dragon right at his tail, biting at it and setting it on fire with its breath. The heat was becoming too much, and he sagged against Celestia, wheezing for breath as the sucking pulled at him mercilessly. It felt like it was starting to reach deeper, as if it would rip his soul out if need be to finish the job.
Silver lost consciousness, suddenly back on Earth, perched on his bed as an alicorn prince. Luna walked in with a smile, which quickly became an expression of horror. "Silver Stars! What happened?"
Silver looked down to see that he was becoming emaciated and drawn. "I... I need more energy. More power. I thought I was strong enough."
Luna rushed to him and presented her neck. "Drink. Drink deep."
Silver barely got his fangs into her and began to nurse from her willingly-given essence. The power of the moon was relatively cool compared to the blaze of the sun. The fading sensation began to recede, and he awoke.
Silver let out a loud and choked gasp before breaking into a coughing fit. He felt sore everywhere, and tired beside. Celestia was softly petting his mane with a hoof. "I thought I lost you..."
Silver smiled gently and tried to rise from her, but his legs didn't want to cooperate. Celestia held him, hugging. "Stay here for now. You've done an amazing thing."
They lay snuggled together as Celestia spoke in gentle words. "I had sought to motivate you, Silver. I wanted to drive you ever onwards to be the best you could be, for yourself, and everypony around you that relies on you. I didn't think you'd be so rash..."
Silver snorted out a half-giggle. "I thought you knew me better than that."
Celestia quirked a smile. "Clearly my mistake, but not a fatal one. Are you feeling better?"
Silver tried to rise again with moderate success. He was shaking and wobbly, but moving. Celestia brushed his hanging member with a fetlock. "Foolish stallion. That was almost your end. You looked awful."
Silver cringed, that tool feeling tender and sore. "Did it work? Your... sister helped."
Celestia perked an ear. "Did she? Hmm... There is a certain poetry in you needing the support of us both to make a true royal heir." She rolled up to her hooves, looking none the worse for wear for the journey. "I'm sorry for what it took out of you. If it's any consolation, I never felt better."
Silver burst into laughter at her words. "I'll try to keep that in mind. Help me to the bath?"
Celestia easily lifted him in her magic and they both retired to the tub, where they soaked, quietly at first. Celestia softly nuzzled the slowly-recovering Silver. "You are truly my husband now. My stallion."
Silver smiled gently. "Does that change much?"
"Of course." Celestia tilted her head faintly. "If any thought your claim to princehood was undeserved before, they have been proven wrong. You have also rose to my challenges, as harsh as they have been, and faced each in your own way." She raised a hoof to lift Silver's tired head. "I may have thought you would fail, but you don't like it when I'm right about predicting ponies, do you?"
Silver nuzzled her hoof lightly. "I live to surprise you, sun butt."
Celestia rolled her eyes. "You may not use that term in public. Besides, what are you? Scribble flank?"
Silver shuffled closed and leaned in against Celestia. "I'm your stallion."
Celestia chuckled softly. "Remember that it is the mare that controls, not the stallion. I will protect you, Silver Stars. You've more than proven worthy of it." A large feathery wing emerged from the water as Celestia wrapped Silver gently, hugging him. "Now let's see if we can't get a nation stabilized, hmm? Compared to rutting me, that should be foal's play."
Aila and Shei returned to find them clean and content looking. Silver had mostly recovered from his draining task, lying limply on the ground, but not looking dead or dying. Aila nudged him. "Laying down already? It's not even halfway through the day! We fetched your bauble, master." She set a box down in front of Silver's nose.
"Thank you." Silver rolled upright and gently plucked up the jewelry in his magic before moving it over to Celestia and quickly wrapping it around the base of her tail. "For my princess."
Celestia spread her wings abruptly. "I thought that would be for Luna!" She looked over her shoulder at the silver band with its talk of the moon and its crescent moons. "What is the meaning of this?"
Silver smiled gently. "It simply says that I can always feel your warmth, even in the dark of night."
Celestia's wings folded back onto her sides as she snorted. "I see... That's very touching." She leaned over and kissed Silver on the tip of his nose. "I do wonder what Lulu will think of it when she sees it." She looked to the girls. "We leave in half-an-hour, be ready for court, and no outbursts today, hmm?"
Shei blushed softly at the admonishment. "I won't, I promise, mistress. Sorry for embarrassing you..."
Silver sat up straight. "You shouldn't feel shame in protecting your sister. That's a noble intent if ever I heard of one. Just..." He rolled a hoof. "Let's not make ourselves look odd in court."
Shei moved off towards her clothes. "Of course, right. I won't do it again, really. Did you eat breakfast? You look like you could use more." She returned to Silver with a plate with a two pomegranates and an orange on it. "You need your strength."
With the food in front of him, his body solidly agreed with Shei, and he tore into the offered fruits eagerly, feeling significantly better for it. "Thank you, I needed that."
Aila snorted softly. "Maybe he wasn't joking. You really do need servants, master. You'd forget your tail if it wasn't attached to you."
Celestia clopped her hooves together in two quick claps. "Enough of that. Let's all be ready to go."
