Bedroom Experiments

Twilight Sparkle and Flash Sentry followed the porter as he carried their bags up the many stairs towards the royal suite of the Canterlot Castle. Their excitement could hardly be contained. They had just been through the most beautiful and lavish ceremony they could have ever dreamed of: their wedding. It had all the ingredients for a proper fairytale recipe, and Twilight truly felt like a princess. She knew that it was considered “girly” to think in such a manner, but she also realized how important it was for her to find a stallion.

Flash had always held sway over her heart and, with the number of male suitors that she had growing exponentially on a daily basis, it became clear that she needed to make a decision. So, she made the obvious, yet heavily criticized one. The shallow Equestrian tabloids made a lot of sport out of her and Flash’s relationship, but she allowed it to go in one ear and right out the other one. She was a young mare in love, and she was not going to allow anypony’s baffling sense of yellow journalism to take that away from her. Flash was hers, and she was his, and the recent proceedings had bound them together forever.

“Your room, Your Majesties,” the porter said as he bowed to the princess and her new prince, “I truly hope your stay is enjoyable.”

“Thank you, Bell Hoof,” Twilight said, “I am sure it will be.”

Flash pulled out fifteen bits and gave it to the veteran castle staff member, who promptly leapt for joy and hugged them both. He then chuckled sheepishly, doffed his cap, and returned downstairs. In all his years working at the castle, he did not remember receiving a tip of such an amount. It certainly showed the generosity of the young royals, and he was very pleased to call them both his superiors and his friends. He turned at the bottom of the stairs and smiled back up to where the door had closed. Young love certainly does warm the heart, he thought, that, and a fifteen bit tip!

Meanwhile, back in the room, Twilight and Flash unpacked their things and settled in for their first evening as husband and wife. They both blushed when they saw that there was only one bed, and forgot for a moment that their oaths tied them in both the day and the night. Their marriage ceremony might have been fun, but now they realized that it was their job to become one. They were no longer separate ponies, but conjoined by their love and affection. The thought that they would wake to each other for the rest of their lives was both comforting and frightening, but they quickly disregarded it.

Flash made the first move, stepping over to his new mate and kissing her cheeks gingerly. “Well…I think you know what comes next.”

She nodded and gulped. “Yeah, I do…but…I’m…nervous.”

“Oh, Twily, there’s no need to be nervous,” Flash said.

“Oh, no?” Twilight asked before pointing at his quaking hooves.

“Alright, alright, so I’m a little bit on edge,” Flash huffed, “but can you blame me? I mean, I’m about to stick my penis inside your vagina!”

Twilight blushed heavily. Even though the terms were scientifically accurate, and now that they were married, completely necessary, she still wished that he hadn’t spoken of them so bluntly and negatively. “Why do you have to talk about them like they’re the devil?” She asked.

“Oh, I’m sorry, Twilight,” he said, pulling her into a hug, “I guess I’m just feeling the pressure. I mean, I have to please you!”

Twilight smiled. “There’s no need for that, baby. You please me just by being in my life!”

“Alright,” Flash said, blushing, “let’s get on with it before things get any mushier.”

They began to kiss deeply, and Flash wound his tongue around Twilight’s, earning some soft sighs of happiness in the process. Their velvety muscles moved in a perfectly beautiful rhythm, leaving them both breathless and mentally begging for more. When they broke apart, Twilight remembered what Rarity had taught her in those quiet moments when the mares discussed her sexuality and dove right for her new husband’s member.

But Flash stopped her, and she gave him an odd look. “Aren’t I supposed to suck you down there?”

“Yes, darling,” Flash responded, “but before you begin, I do have a small request.”

“What’s that?”

“I want to have scientifically accurate sex,” Flash said. He was just as big a lover of books and science as Twilight was, and he was determined to play out a certain formula he’d read about. Apparently, there was a way to achieve a perfect orgasm through pinpoint cunnilingus, fellatio, and intercourse, and he was absolutely bound to the idea. He wanted to give Twilight what she deserved: the height of pleasure. He couldn’t wait until she was squealing and screaming as he went faster and faster, knowing the exact spots to nail in order to give Twilight her special moment.

“Well, baby, you know I’d love nothing more than to honor the scientific method in our pleasurable endeavors,” Twilight responded, “but how is it done?”

“Lean back on the bed and I’ll show you…” Flash said seductively.

Twilight smiled and blushed, but quietly sat down and followed his directions. She spread her legs wide, giving him the most stunning view he’d ever witnessed. Her small cunt seemed to play with itself and tease at his eyes. Its beautiful pink lips begged him to come in and tease them. He also noted that she was already dripping with liquid, signaling that she was ready and willing. He looked at her and then began toying with her flower, tracing circles around it with his tongue. He remembered the article and how there were certain pleasurable checkpoints on the route that he needed to hit. He would plant little kisses on these patches of fur and skin, leaving Twilight absolutely euphoric above him. But it was not overplayed moans and screams that used the air as a pathway to his ears. Instead, they were simple moans that let him know that his task was successful.

Having made three or four laps around her vulva and clitoris, he finally decided to dive in. Once again, he remembered the system he’d read about, and knew exactly where the formula told him to lick her. He would drag his tongue over her lips, savoring the sweetness of her flesh and bodily discharges, before lightly playing with her tender clit. This was where she became louder and louder, and he knew that his theories were working. He felt his penis become as hard as a rock at the wondrous noises, and continued his work diligently, yet gently.

After swallowing a good bit of her vaginal liquid, he got up and climbed on top of her. He knew that the formula demanded her own satisfying oral experience, so he gently pushed his cock into the correct position. “Now, then,” he said, “you need to make two sucks, followed by three swirls with your tongue.”

“Good grief, Flash!” Twilight exclaimed, “you sure have…mapped this out.”

“The piece I read on the formula for proper and perfect sex demanded oral stimulation for both genders, and this was what it recommended for the mare to do.”

Twilight, not wanting to stand in the way of science, shrugged her shoulders and began to lay her mouth onto his shaft. His mouth fell open at the warm, beautiful sensation of her saliva against his bareness and he realized just how much he enjoyed showing his private parts to her. It had been so taboo before this day, but now that they were married, every single burned bridge had been rebuilt. They were on an absolute road to a heaven that some ponies never got to experience. In that moment, with the most amazing mare in all Equestria gently suckling up and down, he felt terrible for them.

But the thoughts exploded as she made her way all the way down to his balls. “Oh! Oh, Twily!” He moaned, “that’s…not…in the formula!”

“Haven’t you ever heard of amending a theory?” She asked with love and seduction as she used a hoof to toy with his sensitive tip.

“Yeah, but-“

“But nothing, my love,” Twilight responded, “your formula sounds fun, but I think I have a much more improved postulate. I believe we should try it out…”

With those words, she got up and crouched on the bed, moving her tail so that he could have unfettered access to her two most secret areas. Her eyelids narrowed until her beautiful purple orbs shone like diamonds, and he could not resist her. He knew of the traditional way to mate, but he also knew of the formula. As much as he loved her and wanted to take her thoughts into account, he also remembered the "guaranteed perfect orgasm" that the scientific method promised. So, he decided to knock her onto her back and try it that way. Using his strength, he overpowered her and jumped on top of her, kneading at her chest fluff with desperate hooves and kissing her deeply. She responded perfectly, wrapping herself around him and rubbing at his member with every ounce of her crotch.

“Oh…fuck me, you big, handsome bastard!” She cursed.

"You aren't mad about me changing back to what we were doing?" He asked.

"Oh, I don't give a fuck! I can feel you brushing my entrance, and I need you inside me! Just screw me until you can't anymore!"

He smiled and slowly pushed himself into her pussy, breaking through the curtains inside and causing some blood to pulse out and stain the comforter. Neither of them seemed to care, though, as he continued to lovingly torture her. His thrusts weren’t violent and rapid, but rather smooth and precise. He would pump himself in and hold himself there, relishing the screams that came with it, before slowly pulling out and repeating the cycle. He knew that quality meant more than quantity, and he had pinpointed her most sensitive area almost off the bat.

His torturous methods were deeply appreciated by his lover, who squealed and shrieked for more. He pushed himself in once again, targeting her G Spot, and hitting a complete bullseye. He held himself there and wiggled back and forth, swiping over her special area multiple times. Each time brought her closer and closer to that wondrous mountaintop of sexual happiness, but he would deny her every single time and pull out. She would giggle, and then he would shove back into her, thus starting the pleasurable agony all over again. Push, scream, giggle, and pull. Push, scream, giggle, and pull. The system was working to perfection, and he knew it. He was in complete control of their first time.

“Alright, my little princess, what would you like now?” He asked as he pulled out again.

“I just wanna CUM!” Twilight squealed, “the torture’s been fun, but please, PLEASE let me cum! Just fuck me hard and let me experience that wonderful, beauteous feeling of euphoria that my friends have told me about! Please, make me cum, my love!”

Flash smiled, ready to do his princess’s bidding. He pumped into her again, only this time, he actually thrusted rhythmically. He took great pride in the amount of screams that emanated from Twilight’s throat, and he bent down so she could bite him. It was a common practice among mating ponies that the mare would give the stallion a small hickey to remember her by. That and, when mares had their orgasms, it was often a violent affair, accompanied by much shaking and shrieking. When he bent over and felt her teeth meet in his skin, he bit back a bit of pain and kissed her cheek before grabbing her and pumping harder than ever. He felt his orgasm coming along as well as hers, and he had a very important question for her.

“In or out?!” He yelled.

“WHAT THE FUCK DO YOU MEAN BY THAT?!” Twilight screamed as her climax began grabbing her by the mane.

“I MEAN, DO YOU WANT ME TO CUM IN OR OUT OF YOUR PUSSY?!”

“IN IT, YOU FUCKING BASTARD!” Twilight shrieked, “CUM INSIDE ME!”

Flash took a moment to think of the potential consequences of such an act, but decided to go along with her request. His thrusts turned even more rapid and the two ponies both screamed as their orgasms slammed into them like freight trains. Twilight shrieked and smacked Flash down to the floor, so she might have all the room she needed to roll around and release her agony. Flash didn’t even have time to put all of his sperm inside of her, as he felt his penis pump out even more after he hit the floor.

He slowly got to his hooves and turned to face his beloved bride. He saw her squirming and shaking in the aftermath of her climax. He knew it was his job to comfort her and bring her back down to Earth, so he gently pulled the covers down and helped his wife underneath them. Then he got into bed and pulled her into him, wrapping his wings around her and allowing her to kiss and nuzzle him as she needed to. In a few moments, her breathing slowed and she cooled her emotions to the point where she could speak properly.

“You’re such a great lover,” she complimented as she nestled further into him, “and a smart stallion. Your formula worked beautifully.”

“I think there are some other experiments I’d like to try at some point,” he said suggestively, giving her a light tap on the rump.

“I’d love to be your partner,” she said as she yawned and fell asleep against him.
