Luna trotted down the huge elaborate hallways of the royal castle. Passing Celestia, she gave a warm greeting to her sleepy older sister, who was on her way to retire in her chamber for the night. Every night after raising the moon, Luna sat upon the throne and magically generated dreams for all of Equestria. After the spell was cast and the ponies were all off to sleep, her schedule was fairly empty. In the wee hours of night she would do her best to focus on study and inventing magical spells, but boredom takes a toll on a princess, and the dreams she generated became more and more sexually driven. She delved deep into the sexual psyche of ponies long and far, seeing the different deviations and fetishes they all kept hidden. She even had began modifying the dreams of her sister. She needed more, she was desperate for any physical contact she could get. That's when she discovered how to put her guards to use.

It all started simple, the night was dark and Luna was done with her work, she had tried to read and study, but boredom quickly set in. She looked up from her book and around the room.There was only one guard posted next to the throne, making the room seem oddly unsymmetrical.

"Guard, is there not supposed to be two of you?" she inquired.
without loosing his vigilance on his post the guard gave a quick answer. "The other guard is sick... do you require assistance?"
"no" she sighed.

She stared at her guard for a moment. He had black fur that contrasting perfectly with the purple armor that was usual for night guards.peeking in-between his flowing tail, she got a look at a sizable package hanging below him. This wasn't the first time she peeked at one of her guards,in fact, she often found her self looking at her guards during the boring hours of the night.

A mischievous thought found its way into her mind, an idea for a spell similar to the dreams she placed into ponies minds. Her horn lit up with a purplish-blue magic that casted light across the throne room. A shudder from her guard was all she needed to know that it worked.

"my guard, do you find me attractive?"
"of course my lady."
"I have a royal order for you, do you think you can handle that?"
"of course my lady."
"I order you to mate with me."

She wasn't too experienced with sex, but she had read many of Fluttershy's adult novels, and wasn't unfamiliar with any of the concepts. She presented herself to the guard and without warning the guards hormone filled brain forced him to mount her.

She couldn't achieve orgasm easily alone, especially without any toys, but with the stallions large erection deep inside her, she lost count of her orgasms. After several minutes of extreme pleasure, the guard pushed into her hard with a final thrust, coating her royal insides with his sticky fluids.

Afterwards the guard trotted back to his post, as her magic lost its power over him, his memory of the last moments faded away.It seemed that her magic deleted all memory of it ever being used after the fact, this proved to be exceedingly useful. This way there were no strings attached, no conveniences. (unless she got pregnant, which was unlikely considering her alicorn biology)She did feel bad, of course, for using her guards like sex-toys, but those feeling faded after the ninth night in a row.

She let the guard try anything he wanted, even anal a few times, but one wasn't enough.She began inviting more and more guards, at one point, she rounded up six guards, each one fighting over her body. She never felt so full, and never so happy.

After weeks of Luna's sexual deviation, she set into a comfortable state. Every new guard would be tested for their sexual prowess, this way, she became to have a very personal understanding of her guards, even if they were unaware of it.One guard in particular stuck out against all the others, Silver Sheath, He was one of the only guards to remember Luna's usage of him. At first she was nervous, but when he confessed his feelings for her and promised he would let her use him any time and in any way she wanted, she appointed him on full time guard duty. He would be at her side every night, and they became attached on a extremely personal level.

Luna liked it rough, and always had... but as she became more and more adventurous she needed more, more power, more domination. That's when she had the an idea.

The royal library contained many magical spells that could change a ponies body for a limited amount of time, only one could generate working stallion biology. The first time she tried it, she tried it alone. From under her body a long Erection sprouted, along with a full looking pair of balls.A quick peek in the mirror showed that she was fairly indistinguishable from a stallion, she was about normal size, maby a bit larger. Its color was much similar to her cutie mark, with purple with bluish-black spots. She attempted masturbation, but as before, she would need some help in order to reach orgasm.

"Silver!" she called out through her chamber door.

The door unlocked and in trotted her royal guard.A blush plastered his face the moment he saw her throbbing erection.
After the moment of shock her blurted out "Care for some help,Luna?"

She didn't even need to use her spell anymore,just the idea of helping Luna cum would be enough for him.
Lowering his neck under himself, he pulled the drawstring on his armor causing the purple steel plates to tumble onto the floor. Silver sheath always felt naked and defenseless without his armor on, even after many times, he still felt nervous in the first moments with her.

"How shall we go about this?" he asked
"Get on your knees , use your mouth." she ordered.

He knelt down low to the ground, allowing the princess to position herself over him, her erection dangling above his head.
Silver sheath wasted no time, He began pushing her erection deep into his mouth, coating it with saliva. The feeling of her erection pushing deep into his mouth, dripping precum down his throat was quite uncomfortable at first, but hearing Luna moan above him with the same pleasurable sound was enough for him to enjoy it.

"ah, ah, im ... mmm im coming!" she whimpered between moans of pleasure

Her legs shaked as she filled his mouth, cum overfilled out the sides of his lips and dripped onto the floor in strands.Under his chest his erection pinned between him and the ground shot out ropes of cum, sticking on his stomach fur and the floor.

"You OK?" She asked while he struggled to swallow the cum left in his mouth.
"... Its a pleasure to please you."

"That's a good boy." She said in a playful manner wiping the seed from the corner of his cheek.
just her saying that was enough to send a few more cumshots from his member, there was not much more he loved in the world than pleasing Luna.

With a magic light her erection zapped away,returning to her regular, more familiar genitalia.

...

The new guards were chosen a few this morning, a new guard would be assigned to her throne room along with silver sheath. She told Silver her plans for "initiation" which he wholeheartedly agreed with.

When luna opened the throne room doors, she was greeted with a unsteady looking guard, perhaps having heard of the rumors surrounding her. His eyes fixed on her, subtly shaking.

"Hello, you must be the new guard on duty."
