If I Must...

Twilight’s jaw cracked as she yawned loud and long. She leaned back from the small wooden desk and stretched. Answering her subjects’ letters always tired her out, and tonight’s workload—all of the correspondence she had received over the past week—was certainly no exception. The tower of letters to be read and responded to loomed high above the short stack that Twilight had gone through so far, and already the two fat candles she had lit were halfway melted..

Another yawn forced its way past her jaws only to be swallowed up in the surrounding darkness. Although this workroom wasn’t particularly large, it seemed difficult to light up; the darkness swallowed any illumination that might otherwise expose its secrets. Gloom pressed in on the small sphere of light that enclosed Twilight’s small mahogany desk.

Suddenly a loud snap like a thousand rubber bands breaking at once slapped Twilight from behind; the large stack of parchment toppled over, and only at the last possible second did Twilight reach out and keep it from falling onto a candle. As soon as she was confident that her castle wasn’t going to burn down, she spun around and opened her mouth only to find that a cloud of smoke had appeared. Before she could think to not breathe, she sucked in a lungful and immediately began to cough. She fell to her knees, coughing and clutching at her neck.

“Twilight Sparkle!” a mare’s voice said from within the cloud. “Is that you?”

Another round of coughing cut Twilight off before she could even begin to answer. Through the tears building in her eyes, she saw the smoke cloud blasted away as the figure hidden inside gave a powerful flap of her wings. Twilight would have gasped in surprise if she wasn’t already gasping for breath.

“Twilight Sparkle, are you well?” Princess Luna furled her wings and knelt by Twilight, laying a hoof on her back. If Twilight’s eyes weren’t forced shut by yet another coughing fit, she would have glared.

At last, after a few minutes of collecting her breath while Luna rubbed her back, Twilight clambered to her hooves. “Luna,” she croaked. Her throat threatened to seize up again at any moment, but at least she could speak. As soon as she counted the number of questions she had, another three popped into her head, so she picked the most important one. “Why are you here?”

Luna lifted an eyebrow, then yanked her hoof away and straightened up. “Yes, the important reason that I am here is a reason of the utmost importance! Equestria is in danger!”

“It is?” Twilight forced all other thoughts from her mind. “What’s wrong? What can I do to help?”

“Equestria is in danger, and in order to save it—” Luna covered her mouth and coughed delicately “—the two of us must make love immediately!”

Twilight nodded. “Okay, that makes sen—” She stopped, mouth hanging open. “I’m sorry, but could you repeat that?”

“Of course,” Luna said. “To save Equestria, the two of us must make love immediately!”

“Immediately?” Twilight asked.

“Immediately!”

“Right here?” Twilight said. “In this room?”

“Your bed chambers shall suffice.”

Twilight’s mouth quirked to the side. “Why are we, uh, making love?”

“I have not the time to explain that now!” Luna glanced around, almost as though whatever threatened Equestria was preparing to leap out of the darkness at her. “The longer we tarry, the closer we all come to certain doom!”

“Well…” Twilight’s voice trailed off until she finally nodded. “If it’s to save Equestria, then of course I’ll help.” She reached out and took Luna’s hoof. “Here, hold on.”

“What—” Luna began.

Twilight’s horn flared, and the entire world around them was sucked into it. A second later reality spewed back out, but instead of the library, they now stood in a candlelit bedroom. Twilight’s four-poster bed, complete with purple sheets and pillows, sat against the crystalline wall.

“Here we are!” Twilight said cheerfully.

Luna put a hoof to her mouth. “In the—in the future, please give more warning before doing that, if you would.”

“Sorry.” Twilight gave an apologetic laugh, then hopped onto the bed. She waited for Luna to take a deep breath and lower her hoof. “So, what do I do—” Her words became a yelp as Princess Luna tackled her. “Luna!”

“Dearest Twilight,” Luna purred, forehooves pinning Twilight to the bed, “if I am not mistaken, you are blushing.”

Twilight’s already feverish cheeks burned even hotter. “Of course I am,” she said, staring up into Luna’s pale-blue eyes. “I’m a little out of my—” She stumbled over her words as Luna leaned in and licked from her collarbone to her ear “—c-comfort zone.” A shudder wracked her body from the wet trail left in her coat.

Luna pulled back just far enough to bump their noses together. “A mare as beautiful and wise as thou’rt hath no need to be nervous.”

“You still use the early-Modern Equestrian dialect?” Twilight asked.

“Only when the mood catcheth my fancy.” Luna’s breath was warm, blooming against Twilight’s face in hot puffs. It smelled like spring flowers both fresh and young.

“Well—” Twilight cleared her throat “I, um—”

Before she could speak further, Luna closed the gap between them, and pressed their lips together in a tight kiss. Where her breath had been warm, her lips were both warm and alive, Twilight realized. They were soft and moist, hot and delicious; Twilight’s eyes closed and she lost track of everything except the feeling of those wonderful lips on hers. She wanted to taste them, to hold on to them forever and ever.

Luna pulled away, making Twilight whine, but a moment later the lips returned in full force. Where the first kiss had been firm and comforting, however, this second one was hungry. Luna took Twilight’s lower lip and sucked on it lightly, then gave it a short tug.

“Don’t stop,” Twilight moaned into Luna’s mouth.

Luna gave a chuckle that vibrated through all of Twilight; she wriggled in delight and giggled, herself. A pair of hooves caressed her back, massaging and probing up and down. Twilight trembled at the touch.

“Twilight,” Luna whispered, running a hoof up and down the other mare’s belly. “Are you prepared?”

“Yes,” Twilight answered as she leaned in to plant a soft kiss on Luna’s muzzle.

“There is a spell for pleasuring a mare.” Luna leaned away, but didn’t release her embrace. “Casting it is simple, but using it is less so. Might I demonstrate it for you?”

Twilight’s ears had perked up at the word “spell”. “Yes, of course!”

“Very well,” Luna said, grinning. “Do pay attention, although if you cannot, ‘tis through no fault of your own.” A dark-blue nimbus of light appeared around her horn.

“Why wouldn’t I be able to—”

Luna’s horn flared, and a ribbon of magic snaked out of it and down between Twilight’s legs. Twilight couldn’t keep herself from yelping as the spell probed at her lips.

“Simply relax,” Luna said in a soft, comforting voice, pulling Twilight close. “I will not harm you.”

“O-of course not,” Twilight said, although the last word ended in a yelp; Luna’s magic pushed its way inside, then explored. It gently pushed on all sides, making Twilight shudder in anticipation. “That’s—that’s nice.” Her voice sounded harsh and raspy in her ears.

As Luna’s spell probed about, Twilight felt it begin to swell. It happened slowly—so slowly that at first she wondered if she was imagining it—but within a few minutes, it had inflated so that it filled her almost entirely.

She felt Luna’s breath against her ear. “Follow’st thou my technique?” Luna whispered, voice hot and moist.

“Y-yeah,” Twilight said.

No sooner had she responded than the magic changed. It began to pulsate inside her, moderately at first, but faster and faster. Twilight’s heartbeat hammered in her ears as the spell pushed and throbbed against her. Her breathing quickened in time with the pulses. In and out, short and shallow, faster and faster and faster. She squeezed the bulging knot of energy as best she could in short, rapid bursts.

Everything in the room grew both brighter and darker at the same time, so Twilight closed her eyes. Without sight, she could focus entirely on what was happening inside her. She felt Luna’s embrace tighten, and she gripped harder in return.

“Don’t stop,” Twilight panted, licking her lips. “Please.”

“I won’t.”

The spell pulled out a bit, and Twilight gave a short whine. The whine melted into a loud moan as Luna rammed her magic back in, then pulled out again only to slam it in once more. The pulsating, the probing, and the thrusting was too much. Twilight’s mouth opened and her tongue lolled, but she didn’t notice. Even Luna’s hooves holding her tightly barely registered; all that mattered right then was that painfully delightful bundle of magic thrusting in and out, over and over and over again.

She felt herself responding, and in a moment of surreal clarity realized that the bed sheets would require a very thorough cleaning afterwards, ideally before Spike woke up. That is, assuming her now-rhythmic moaning hadn’t woken him up already. A second later, she had forgotten all about this line of thought.

“You like it?” Luna whispered.

“Yes!” Twilight gasped, voice cracking.

The thrusts came faster now. Twilight could feel a pressure building inside of her that existed separate from the magical swelling member, and every thrust simply added to it. Her mind stopped registering sounds. She could taste the acrid sweat on her lips, could smell it as it poured down her face, but even that was secondary to the growing sense that in her groin was about to burst, and that it had to happen soon or she was going to go utterly mad.

Then the spell began to vibrate, and Twilight lost what little control she had left.

The dam burst inside; her sweaty body convulsed once, then twice, over and over again as the purest pleasure she had ever experienced slammed into her like a series of tidal waves. She was helpless to resist the searing delight that tossed her about like a rag doll, but then she felt the crushing grip of Luna’s embrace about her. She stopped resisting and cried out in the throes of orgasm as the spell pulsed and vibrated and thrust, all at the same time.

After what felt like hours, Twilight regained full awareness. Where her body was exposed to the air, it felt cold and clammy, likely a result of the sour-smelling sweat drenching her coat. The breaths rattled in her throat. At some point, Luna had released her magic, and Twilight felt empty now that it was gone.

“Ssssshh,” she could hear Luna whispering in her ear. “Sssssh, it’s alright.”

“Luna!” Twilight said in a choked voice, and only then did she realize that the sweat on her face was mixed with tears. “Luna, I—I don’t know what to say.”

“It’s alright.” Luna stroked her lover’s mane. “We will speak in a few—”

Twilight pulled back, then bulled forward, stealing Luna’s breath in a hot kiss. She forced the other mare’s lips open, and their eager tongues wrapped around each other. Their bodies writhed together in an effort to get even closer than was possible. A loud smack rang out as Twilight broke the kiss off.

“So,” she said with a mischievous grin, “mind if I show you how good a student I am?”

Luna’s eyes widened for a moment before a wide smile spread across her face. “Pray, do.”

Twilight and Luna leaned back against the headboard, each with a hoof around the other’s shoulders. Twilight passed over a pixie stick, then tore off the end of one for herself.

“Twilight Sparkle,” Luna said as she set down her pixie stick, “this was—this was the greatest night I have had in more than a thousand years. But there is something I must confess.”

Twilight took a long draw of granulated sugar. “Equestria isn’t actually in danger?”

“You see, Equestria isn’t actually in—” Luna paused and shut her mouth with a snap. A long moment passed in silence. “You knew?”

“Of course I knew,” Twilight said with a giggle. “What kind of danger is there that could be solved with sex?”

“Well, there could have been danger…” Luna said, sticking out her lower lip in a pout. After a moment, her expression grew serious. “But if you knew from the start, then why did you go along with it?”

“Because you’re a wonderful pony, and I want to get to know you better.” Twilight sucked on the pixie stick again, then tossed it onto the nightstand. “And I think I know just how to do that.”

Luna fiddled with the end of her mane. “What do you propose?”

“Would you like to save Equestria again?”
