The Elements of Harmony Test the Orgasmatron

The illustrious, studious, and regal Princess Twilight Sparkle lay, spread eagle, across Princess Celestia's pink-sheeted mattress. To her feet, Celestia's recent invention, The Orgasmatron, stood. The device's defining feature, it's toy-tipped rod, protruded outward, the "toy" a mere few inches from Twilight's love. Nervous sweat dropped from Twilight's forehead. This was due both to her current position, as well as the fact that Princess Celestia sat in a wooden chair, a mere few feet to the left of the bed. Outside of the room, the other five elements waited for their turns to test the device.

"Princess, I'm all for testing your... device... for you," Twilight began, nervously "But do you really have to be in here while I do it?"

Princess Celestia sat, as previously stated, in a wooden chair to the left of her bed. She was clad in a snow-white dress that was coated in neon-rainbow colored floral designs. Such a proper, well-stitched outfit clashed with the scene that was next to the Princess in a manner that was almost comical. In Celestia's magical grip, a small note pad and a pen were present, as well as The Orgasmatron's remote. Celestia looked up at Twilight.

"Of course I have to be in here, Twilight." Celestia said, in response to Twilight's question. "I have to record your reactions to the device. If you're uncomfortable, I can strip down, too."

"No, no!" Twilight began, dreading the thought of her position becoming even more awkward. "There'll be no need for that. I'll be fine."

"Suit yourself." Celestia joked. "Are you ready to begin the tests?"

"As ready as I can force myself to be..." Twilight said, awkwardly.

"Great!" Celestia replied, ignoring Twilight's uncomfortable state. "How the test will work is simple. I'll turn the tool on on it's lowest setting, and we'll gradually increase it's speed as the test goes on. This will continue until you either climax, or can't handle any more. Understood?"

"Y-Yes... I think I understand..." Twilight said, uncomfortably.

"Wunderbar." Celestia said. "I'm going to turn the device on, now."

Twilight nodded. Without any further conversation being made, Celestia flicked the device onto it's lowest setting of speed. With a quiet whirring noise, the device powered on. Before Twilight could do anything, she noticed the toy at the tip of the machine's rod being pushed forward. After a few seconds, it had been pushed against Twilight's folds. A moment passed, and the toy had separated her folds. It had quickly entered her body. Twilight stiffened up at this feeling, before giving out a moan.

"Slow down, Twilight." Celestia jeered. "We're still only on the lowest setting."

Celestia pushed another button on the Orgasmatron's remote, causing every inch of the toy, except for it's tip, to pull out of Twilight's trail. Before long, however, the toy had pushed back in. It repeated this several times. Twilight's eyes closed. Her waist began lifting in a seemingly instinctive manner. Twilight's body began rocking in sync with the device's thrusts. Celestia pushed another button on the remote, causing the toy at the tip of the rod to begin vibrating. This caused Twilight to give out a loud "Ah!". This yelp quickly dissolved into a moan. Celestia turned her head to Twilight's waist, noticing the slick wetness between her legs.

"Enjoying the test, Twily?" Celestia joked.

"Y-Yes..." Twilight managed to moan out.

"Alright, I'm going to increase the speed, now. This is the only time that I'll let you know before I do this. Understood?" Celestia asked.

Twilight, too lost in her own pleasure to vocally respond, simply moaned and nodded her head. Celestia gave a quiet laugh at this, before flicking the device to it's next speed setting. The sudden increase in speed caused Twilight to give another yelp, which was followed by a moan that had mimicked the previous yelp's. Twilight began grinding her hips into the air. Her wings completely erect, Twilight moaned with passion as the device penetrated her.

Celestia once again increased the device's speed, earning another yelp from Twilight. Celestia, wanting to make the test enjoyable for Twilight, flicked another button on the remote, This caused the device's toy to begin rotating, alternating between a clockwise and counter clockwise movement every few moments. This caused Twilight's moans to increase in potency, and her hips to begin rhythmically bucking.

Twilight, feeling the simultaneous force from the device's rotations, vibrations, and thrusts, couldn't ask for a better feeling between her folds. The feeling that this device had brought upon was unlike anything that any stallion could hope to mimic. After only Celestia knows how long, however, Twilight could feel her yearning clitoris just begging to be massaged. Using her right hoof, Twilight began rubbing the tiny nub of flesh.

Celestia once again increased the device's speed. The device, now only one setting away from it's maximum speed, was thrusting into Twilight with enough speed to force Twilight up and down. Twilight certainly didn't seem to mind, though. She squealed, moaned, and cried out in such a way that assured to Celestia that she was having a good time.

After a while, Twilight could feel her walls begin to contract around the toy. She knew that her climax was steadily approaching. The only thing that Twilight did not enjoy about the device was that it was unable to have it's own climax, inside of her. That certainly wasn't going to hinder her enjoyment of it, too much, though.

Celestia, noticing Twilight's convulsing movements, also knew that the mare was approaching her climax. Knowing this, Celestia flicked the device onto it's fasted speed setting. This caused Twilight to cry out in ecstasy.

"Ooh! OOH! P-Princess!" She squealed. "I-I think I'm going to ~AH!"~ I think I'm going to come!"

Celestia nodded her head, and began writing in her sketch pad. She then looked back at Twilight. Twilight, who was grinding with more force than before, was crying out and moaning with great volume. Her legs and hips were bucking, uncontrollably. Before long, Twilight reached her peak. She practically screamed in euphoria as an exuberant stream of liquid expelled from between her folds. She then collapsed, finished. Celestia, knowing that Twilight had hit her peak, turned the device off. Twilight used her magic to pull the device's toy out from in between her folds.

"So... How was it?" Celestia asked the exhausted princess.

"It... It was magnificent. I've never felt anything like it." Twilight replied, weakly. "Princess... Can I use your shower?"

"Of course." Celestia replied, pointing her horn in the direction of her bedroom's neighboring bathroom.

Twilight bowed, respectfully, before walking into the bathroom, and closing the door. Celestia sighed, looked at her notes, and approached the door to the hallway. She opened the door, and greeted the five awaiting elements who rested outside of it with a bow.

"How... How was she?" Rainbow Dash asked Celestia.

"Twilight enjoyed the device. She described it as "magnificent". She's in the shower, right now." Celestia replied.

The princess then stepped to her side, leaving a gap in the door just large enough for one of the other mares to step through.

"So, who's next?" Celestia asked.

Out of all of the mares present, Celestia was surprised to see that Rarity was the one who had stepped forward.

"I would... Like to test your device." Rarity said, raising a hoof.

"Sounds like a plan." Celestia chuckled out. "Let's."

With this, the two entered the room, and closed the door, behind them.
