The First Time

Author's Note

All the characters in this story, although have a human body, stayed with their hind hooves, horns and wings.

The First Time

Flash Sentry had always been a very dedicated Royal Guard. Since he was a young colt who dreamed of one day wear an armor and protect those who were in need. It was a dream that come true when he donned his armor for the first time, when he started his dreamed career.

When he received an invitation to join the Crystal Empire Royal Guard, Flash was delighted, feeling that this would be an improvement on his career. However, all this cheer was gunned down when he was assigned to his post: Princess Cadance and Prince Shining Armor’s room guard.

It was a lousy job, as this involved listening to royal couple making sex every day, both wrenching of pleasure and making Flash Sentry imagine the entire scene. Of course they used to make a magic sound barrier to prevent those who were outside of hearing room, but while they were doing the coitus, their concentration on the spell decreased and, despite prevent those who were passing through the hallway of hearing them, it did not stopped the person who was right in front of the door of hearing them.

One day, Shining Armor had to go on a trip for a week to deal with important Royal Guard business and other things. When he heard the news, Flash was a bit relieved because he thought he wouldn't have to hear moans of pleasure, while he was at his post, at least until his captain’s return.

However, on the night following Shining’s departure, Flash was quiet in his post until he started hearing Cadance giving moans, but moans of pleasure, similar to those that she did when she had sex with Shining. Flash rolled his eyes, not wanting to believe that even with his captain out, he could not have peace and quiet.

Later, he asked about the reason for Cadance was giving moans like those. For a moment, he thought the princess of love had a lover, but discarded that idea, because he knew how the royal couple loved each other. In fact, it was their love for each other that saved Equestria from the Changelings.

But then he realized what might be happening inside of those four walls: Princess Cadance should be masturbating herself.

Cadance’s moans made up in Flash an overwhelming desire, a desire of lust which, when mixed with his desire of giving Cadance the payback for all the boners that she had given him thanks to her moans and screams, led him to extend a hand to the handle of the door and get in.

Moving his hooves slowly, Flash entered cautiously, closing the door behind him quietly. He advanced cautiously and hiding he could see Cadance lying on her huge bed, dressed with a white shirt with the top buttons untied, with a blue mini skirt and no underwear, while had one of her hands under her skirt to make masturbation and the other playing with one of her breasts.

Flash then began to take off his armor, making sure he was not making to much noise. However, Cadance was so entertained with what she was doing she didn’t even saw him. Flash landed silently the parts of his armor on the ground, taking off then his chain mail shirt and sweater that was underneath it, staying shirtless. But he didn't stop there, because she took off his pants and then his boxer brief, getting completely naked.

After undressing, Flash, without hesitation, walked up to the bed where there was the princess that he intended to dominate. He climbed on the bed, advanced to her and gave her a big kiss on the mouth, while taking one of his hands under her skirt and began to play with her pussy and took the other to the other Cadance’s breast. Cadance moaned of pleasure.

Although she knew that wasn't her husband, she didn’t dare to move Flash away, because he had given her what she wanted, what she had every night before her husband had to travel: caresses in her most intimate parts, while making tongue fights. They stayed that way for a few minutes and all the pleasure that Cadance felt made her cum several times.

Flash then broke the kiss and retreated, standing up and putting himself ahead of the end of the bed. Cadance could see his entire naked body. In short, he wasn't as muscled as Shining, but nevertheless, that was not what Cadance cared about. She didn't care aboute the pectorals, the abdominals or the strength of the arms and legs. There was only one part of the stallions that the princess of love admired the most when it comes to sex: the dick; and, when she saw Flash’s dick, her eyes were bulging with the shock.

Shining’s dick was the size of a normal human dick, even slightly longer, but Flash’s... Cadance didn't even have words to describe what she was seeing. It seemed to be the size of a big and virile horse dick. Never before she had seen a cock like that, not even in the images of pornographic magazines for women she used to read.

Faced with this image, Cadance licked her lips lustfully and hungrily. Seeing how she stayed when Cadance saw his dick, Flash smirked and asked her:

"See something you like, princess?"

She looked at him and replied:

"In fact, I see. But first, I must get at it at its hardest. That's how I do things."

Cadance then stood up, placing herself in front of Flash. She then grabbed him and then pushed him into the bed, where he leaned with his arms. The princess of love smirked to Flash and, using her magic, she made a song start playing. It was a song used many times by the strippers.

And, in fact, Cadance started dancing in a very seductive way, wagging her ass, while she began to untie her shirt in a sensual way. As soon as she finished untying the shirt, Cadance opened it suddenly, showing Flash her wonderful breasts. She then removed her shirt and threw it to Flash, falling on top of his chest. He took it and sniffed it, sensing a slightly musky smell.

Then, Cadance approached Flash and sat on his legs and the Royal Guard sank his face in the middle of Cadance’s breast. She moaned with pleasure, while she was feeling Flash going through her chest.

Then she pushed Flash away, making he fall on his back on the bed and then stood up, starting then to withdraw her mini skirt. She did it slowly, turning her ass to Flash while taking the mini skirt off. Flash saw her buttocks appearing. While watching the striptease, Flash could feel his cock getting even more erect. Cadance took the mini skirt off and then walked in Flash’s direction, while the music stopped.

She put herself on him and the two started kissing while he took his hands to her ass and fondled it. The two bodies touched and scrubbed each other, sharing the warmth that they emitted.

It was then that Flash was over Cadance and departed her legs, approached his member of her pussy and penetrated it by her vagina up. That made Cadance drop long and loud moan. The fact of having a dick that size into her own body made her find herself in another world and, when Flash started thrusting, the moans increased in intensity.

"Yes... Yes! YEAHHH!! "Cadance yelled, full of pleasure. "Don't stop, Flash! Continue! Yes, KEEP GOING!"

It didn’t take long until the two get to the top of their orgasm and have a mixture of fluids in the penetration area.

It was the best sexual experience Cadance had ever experienced. Not even Shining could give her the pleasure that Flash was giving... and for a long time. Yes, because all the action goes for days, to be exact all week. They ate the food that Cadance’s magic invoked, but they did so while having sex.

She couldn't believe that was really happening. She never had sex for days in a row without stopping before, not even to eat or sleep. Not only Flash had a bigger penis than Shining’s, but he also could have non-stop sex for days and days while Shining Armor only could do it for a few hours. Flash was the stallion with more strength and energy that she has ever known.

On the last day of the week, the day Shining would return from his trip, Cadance and Flash let themselves finally fall on the bed, panting, ceasing finally the long duration of the coitus.

"Wow!" Cadance exclaimed. "I… I don't even have words."

"Did you like it?" Flash asked.

"Like it?" Cadance repeated. "I loved it! I had never had sex like this before."

There was a silence and then Cadance said:

"Listen, Flash, this doesn't change anything, you know. I, in spite of everything, still love Shining, even if, after this, he doesn't satisfy me sexually."

"Don't worry, Princess" Flash answered her. "I also do not intend to have your love. I just wanted to give you the payback for all the images that you made me imagine during the times you had sex with your husband, while I was on watch to your room."

"Shining will be here in a couple of hours" she said, as she stood up. "I better go take a shower."

She then looked to Flash, who still had his dick fully erect, and added:

"If possible, with a stallion that made me feel as the luckiest mare with his wonderful dick."

Although briefly surprised Princess Cadance still wanted more of his wonderful dick, Flash smiled and then stood up and the two headed to the bathroom, where they took a shower, while Cadance was possessed by her winged lover once more, while the water rampaged through their bodies.

Shortly after this final act, both dried each other, while Flash gave kisses to Cadance’s whole body. She then wore one of her dresses, while Flash wore his boxer brief, his pants, his sweaters and then his armor.

Together, acting as princess and guard they were, they went to receive Shining in the train station. After he leaves the train, carrying his bag, Cadance ran to him, saying:

"Shining, my dear!"

The two hugged and then Cadance said:

"I missed you so much."

"And I missed you too, my love" he replied, finishing the hug with his wife. "How did the things go here?"

"Not very well" Cadance replied. "Without you, I felt terribly lonely. Fortunately, Flash came up to me and helped me with my loneliness."

She then made to the guard a seductive look. It cost a lot to Flash to not give a laugh or something because his captain had no idea how he had managed to deal with his wife’s loneliness.

"Seriously?" Shining asked, turning to Flash. "I am very happy to hear that. Very well, cadet, I’m glad you helped my wife not to miss me too much."

"It was nothing, sir" Flash replied, bowing his head. "I just did my duty."

"Honey, could I suggest something?" Cadance asked. "I know that the Royal Guard affairs are your responsibility, but I think you could make Flash Sentry into my personal bodyguard. So, I could have company when we're not together."

She made one more seductive look to Flash, a look full of lust and desire.

"It seems to me a good idea" Shining Armor replied, turning then to Flash. "Cadet Flash Sentry, from now on, you shall be my wife's personal bodyguard. Be sure you keep her safe and that you will make her company whenever she wishes."

"Yes, sir" he replied.

Of course Shining didn't know that by doing this, he would be giving her wife more opportunities to be with his new personal sex toy. Despite Cadance still loved Shining Armor, she now had a stallion that was better than him in the bed and that could satisfy her lust whenever she wanted.
