"You are quite fortunate you know." Princess Celestia commented, walking along the halls of Canterlot Castle. At her side, nervous, yet curious as what was to come, was Shining Armor; the stallion in his guard armor. "If it wasn't for Cadance's constant nagging, I may have overlooked you for this."
"I-I'm sorry." Armor replied, hanging his head low as he followed the Princess. He had only been in the guard for a few months, and while rumors of his transition only being possible because of his relation to Princess Cadance, he still felt like Celestia did not fully approve of him. This was his chance to make an impression. "A-and what is the Trial of the Captain?"
"A trial of willpower and endurance." Celestia stated, her tone sounding far more serious than before. "You see, being Captain of Royal Guard is about how to handle difficult, almost impossible choices and situations." Being let into a dark room, she ignited her horn. The room became suddenly enveloped in both an illumination and what appeared to be a soundproof spell. "As well as how loyal you are to your Princess."
"I-I-I'll do whatever it takes." Armor declared, only just noticing just how sweet Celestia smelled. Getting a better look, he also noticed how this was not any ordinary room. This was the Princess' own personal chambers; the source of countless wet dreams among the guards, both cadets and veterans. "A-a-an what are we going to do?"
"I am going to test you, and you will do as you are ordered." Celestia replied, her tone almost piercing Armor's mind. "Now, I am ordering you to disrobe and lay on the bed."
Armor was shocked, almost thinking he misheard the Princess. This couldn't be true, could it? Did Celestia just as him, a regular guard, and lover to her niece, to get naked and lay on her royal bed?! But what else could he do? He had to obey his Princess. Maybe this was just part of the trial, a way to show his obedience to her orders, no matter how strange. Yes, that had to be it. Gulping hard, he took off her armor, but the tension, as well as Celestia's sweet smell was making him hard. His cock was slowly making its way out of his sheath. Nervously, he tried to make his way to the bed without her noticed. But as he sat on the bed, his cock was already at half mast.
"Well now, that was fast." Celestia smirked, her gaze running up and down Armor's body as she slowly approached him. "Usually I have to coerce it out, but you've already anticipated my orders." Leaning in, her hot breath kissed at Armor's cock, making it twitch slightly. "Not bad, not bad."
"W-w-w-what are you doing?" Armor asked, his nervous tone making him sound even more timid than before. "I-i-i-is this part of the trial?"
"That and more." Celestia teased, using her magic to readjust Armor so he was now laying in the middle, with the Princess positioning herself so she was facing away from him. "Now, I believe we can begin." Slowly, she lowered herself on the stallion's cock, her soaked pussy easily taking his thick size. "Your trial will run a full twenty four hours...and it begins...NOW!"
Slamming down hard, Armor gritted his teeth as he fired off his first of what would be countless orgasms in the Princess' pussy. Her womb was instantly saturated with his seed, but she kept on riding. Her ass bounced hard on the stallion, not giving him a moment to recover as her pussy squeezed against his length. This was like a dream come true, a wish he didn't know he wanted. Princess Celestia, the alicorn who was like a mother to all of Equestria, was not riding on his lowly, guard cock with the talents of a master courtesan. Huffing, Armor knew he wasn't going to last at this rate, especially given how sensitive he was from his first spurt. But he had to do this, he had to prove his worth, not only to Celestia, but to Cadance.
The next twenty four hours were the slowest to have ever pass the stallion. Armor couldn't feel anything, and yet he had kept his focus, as best as he could. More times than he could count, he felt he was ready to give up, but he carried on. Even as the minutes were reaching their end, Celestia was reaching her own limits. The bed was soaked in their cum and juices. Feeling the last of his strength leaving him, Armor held out as long as he could; until, finally, Celestia's alluring flank stopped. Settling for a moment, the Princess trembled as she let out a soft moan. Her noise was so seductive, the overly sensitive stallion gasped as he let out another large orgasm. Despite her own fortitude, Celestia felt the brunt of her own orgasms. Her belly was swollen, heavy with Armor's numerous loads.
"Well now, that was very unexpected." Celestia cooed, slowly lifting herself off Armor's cock; the shaft was caked with the countless orgasms from both himself and the princess. "Congratulations, Shining Armor. For having endured the twenty four hour fuck gauntlet, you're now the Captain of the Royal Guard." Looking over to him, she could tell he was just barely hanging on to consciousness, but his cock continued to twitch as if it was ready for more. Smirking, she couldn't help but giggle at it. "Do a good enough job, and who knows. Maybe I'll let you marry Cadance."
"I won't...let you down." Armor replied, heavily panting between words. "J-just give me a moment, to catch my breath."
"Already quick to continue servicing me?" Celestia asked, raising an eyebrow. "I can see why Cadance loves you do." Looking down at the massive amount of cum gushing out of her, a playful thought ran across her mind. "Who knows, maybe she won't be the only alicorn you knock up."
