The Possibilities of Potions

Rainbow hobbled out of the bed, her legs weak. She made her way across the room to the box, and found the mare transformation potion right where she’d left it. Bringing it back over, she rolled into the sheets beside Twilight and handed her the bottle.

While Twilight drank, Rainbow gave a relaxed sigh. She wasn’t sure how the day could get better, but she was willing to give it a shot.

“Here you go,” said Twilight, her voice returned to normal. Rainbow took the bottle and sipped from it. Soon the transformation hit her, and she grunted as her body shrank back to its original form.

She set the bottle on the nightstand, and then turned back to Twilight. “So, what now?”

Twilight grinned. “You’ve had a sampling of all the available dishes. I’d like to get a taste.”

Rainbow nodded. “Okay,” she said with a small smile, “but I’m thirsty, too.” She crawled down the bed, where she swung her leg up and over Twilight, straddling her face. Before her, Twilight’s legs spread to reveal her tail and her wonderful little privates. Rainbow rubbed them with her nose.

Between her own legs, Rainbow felt a soft, wet touch on her slit. She was a little surprised that she could even get aroused at this point, but after another few licks she was wetter than Twilight’s tongue alone could account for. Twilight leaned up and pressed her tongue firmly at the bottom of Rainbow’s pussy, and she felt a hot, slick sensation as it burrowed inside her.

Humming with delight, she began licking Twilight. Her tongue ran between the unicorn’s velvety folds. She could taste Twilight’s arousal. Her nose was filled with the sweet scent of it, and she felt her own loins grow hotter.

Rainbow felt Twilight’s tongue exploring deeper. She purred as it rubbed over ridges and bumps, wiggling up and down. It wasn’t as filling as a dick, but it was much gentler. Rainbow closed her eyes and thrust her tongue inside Twilight.

Beneath her, Twilight put her hooves on Rainbow's flanks and pulled them down onto her face. She kept tonguing Rainbow, flicking in and out of her ever-wetter pussy. Rainbow returned the motion, trying to see if she could reach the end of Twilight’s tunnel. Her tongue wasn’t long enough, but as she thrust it deeper inside, Twilight began grinding up against her muzzle.

Their pace was measured, almost leisurely. They were both tired from the exertion of so many climaxes, so they were willing to let these last ones come in their own time. Rainbow and Twilight licked and sucked and prodded in slow, tender motions. Rainbow felt a new sense of enjoyment as she realized that they were finally pleasuring each other in their true bodies. It felt more personal, somehow.

Twilight’s tail began swishing back and forth in an involuntary rhythm. It tickled Rainbow’s nose, drawing a smile. Rainbow pushed her tongue up against the bottom of Twilight’s pussy, and slowly drew it out like she was licking the side of a popsicle.

Twilight shuddered beneath her, but it wasn’t yet the telltale pre-climax shake that Rainbow had come to expect. Actually, she was starting to think she’d hit that state before Twilight; the tongue inside her was taking her breath away.

Deciding this was one contest she could lose, Rainbow began idly running her tongue in a tall oval around the outside of Twilight’s pussy. It brushed against her clit on every pass, drawing a little squeak. Below her, Twilight’s tongue was slipping in and out of her like it had Sugar Glider poured on it.

It felt like she was climbing a huge hill, a rising sense of feathery height gradually filling her up. Rainbow slowly lathered saliva on Twilight’s clit, watching her tail flick with every rub. She heard a moan from beneath her, and grazed the button with her upper teeth. Twilight tensed, and then Rainbow felt the tongue leave her.

Twilight began teasing Rainbow’s clit in turn, drawing labored breaths. Rainbow gently rocked her hips back and forth over Twilight’s mouth, reveling in the slow, measured strokes of her tongue. She was close to the peak of the hill, her entire body felt suffused with heat. Pressure built inside her loins, a bubble of pleasure just waiting to pop.

She crested the hill at last, and the bubble burst. Rainbow came soft and slow, with a wordless noise of happiness buzzing in her throat. Her pelvis gently ground against Twilight’s mouth. Twilight’s tongue lapped at her dripping folds, guiding her down from her climax like a warm, wet beacon.

Rainbow cooed with delight, and slumped. Twilight leaned her head back on the pillow to get comfortable, and rubbed her hoof on Rainbow’s flank.

Only one thing left to do. Twilight’s pussy was, to put it mildly, moist. Rainbow dived back into the soaking slit, reveling in the flavor. Twilight squirmed as Rainbow licked her, and clenched her butt. It was the little things that made the sight so arousing; the way she twitched when Rainbow's tongue hit just the right spot inside her, the sticky droplets of white caught in her tail, the shiny patches in her fur where the Sugar Glider and Twilight's own, natural lubricant mixed.

Rainbow pulled back out to start on the clit once more. Twilight moaned quietly as Rainbow teased the sensitive little button. By Celestia, I love the noises she makes. Rainbow tweaked it with her mouth and then rubbed her nose against it. Finally, she pursed her lips tightly and suckled it. Beneath her, Twilight shook, and Rainbow grinned.

Twilight came again, as wet and wild as the first time. Rainbow covered Twilight’s pussy with her mouth, riding it up and down as her pelvis pulsed. Juicy squirts filled her mouth, and she drank them down like honey. Twilight’s spasms continued for what seemed like ages, but Rainbow stayed on her for the duration.

At last, the shudders subsided. Rainbow licked up the last few drops, savoring the taste. Twilight's chest was heaving under her, and her butt was still clenching and unclenching as the muscle twitches faded. Rainbow leaned down and planted a long, tender kiss on Twilight's damp, pink folds.

She crawled back up around to Twilight, finding the unicorn’s face flushed blank with ecstasy. She gave her a light peck on the cheek, leaving a wet mark. Twilight rolled her head over and smiled, her eyes half-lidded with sleepy satisfaction. “Kiss me again.”

Rainbow closed her eyes and complied. Their lips met in the best kiss she had ever had. It wasn’t as passionate or invasive as their earlier one, but it was warmer and deeper and filled with some elusive quality Rainbow thought she might label intimacy. They melted into each other, and Rainbow wrapped her forelegs around Twilight to pull her closer.

When did this go from simple rutting to making love? Rainbow’s mouth took a brief detour to suck on Twilight’s bottom lip, before rejoining the kiss. I think Twilight said it, earlier. We know each other inside and out, better than we ever could have without those potions. Wherever you are, Zecora... thanks.

Finally, they pulled their mouths apart. Nuzzling her head up against Twilight’s shoulder, Rainbow sighed in total satisfaction. They cuddled for a few minutes, gently rubbing their hooves on each other’s fur, relaxing in the aftermath of nearly three hours of lovemaking.

Rainbow opened her eyes and kissed Twilight’s neck again. “So, what now?”

“Now?” Twilight hugged her. “I don’t know. I’ve never felt this happy and, and... full, before.”

“Full? Twilight, I’m a mare again, remember?”

Twilight kissed her again. “It’s a different kind of full.”

“I know what you mean,” said Rainbow with a smile, tracing Twilight’s cheek with a hoof. “Me too.”

They lay together for a little while, lost in each other’s eyes. Rainbow felt like she could spend the rest of the week in bed with Twilight, just sitting like this, holding each other. She smiled. “We could go to sleep.”

Twilight laughed. “I may have to buy a new bed, first.” She ran a hoof through Rainbow’s multicolored hair. “Your mane is beautiful, Rainbow, have I ever told you that?”

“Yes,” said Rainbow, looking into Twilight’s eyes and grinning. “But you can tell me again.”

Twilight rolled her eyes and closed them. Her mouth curled. “Aha, that’s what we should do.”

“Hm?”

“Take a bath.”

Rainbow murmured in agreement. “Is your tub big enough for two?”

“Sure is.” Twilight opened her eyes happily. “Let’s go put some bubbles in the water. I want to wash your mane. I made a bit of a mess in it earlier, and I want to make it up to you.”

“Okay,” said Rainbow, rubbing Twilight’s belly. “When you’re done, I’d be happy to return the favor.”

“Thank you,” said Twilight, giving her one more kiss on the lips. “For everything.”

Rainbow dived through the cloud, bursting from the other side with a mighty flap of her wings. She shook herself, raining little droplets of water down toward the ground far below. Looping up again, she spotted her floating house, making a beeline for the entrance.

She landed by the mailbox, stretching her legs in post-flight cooldown. Ponyville would be having another gorgeous morning, thanks to her efforts. Rainbow smiled and checked her mail. The postmare had been by, and she found a cluster of letters inside.

Flipping through them as she walked up to her front door, Rainbow folded her wings to her sides. “Bill... bill... ad... bill...” She paused, finding a lavender purple envelope in the stack. “From Twilight...” Opening the letter with a spark of excitement, she scanned the words.

Dear Rainbow Dash,

It’s been three weeks since you helped me run those potion experiments, and I’m happy to report that I’ve finally gotten some results. Now, normally I’d go over the data with Spike, but I’m afraid he’s going to be busy all day running a list of errands for me. A very long list. Since you were so instrumental in the tests, I thought you might like to come over and have a look. I had Zecora mix up a few more bottles, to ensure our experiment can be repeated with full scientific rigor. I’ve cleared my whole afternoon. If you’re interested, please come over at your earliest convenience.

Love, Twilight Sparkle

P.S.: I’ve been working on a new cotton waterproofing spell I think you’ll like.

P.P.S.: It’s so hot out! Bring some water with you. We may need to re-hydrate.

Rainbow finished the letter with a smile. She dropped the letters on her doorstep. “Of course I’ll come,” she said, laughing. “After all, I am a great lover of the sciences.”

Grabbing a fluffy bit of cloud to use for drinking water later, Rainbow took off. Her body floated down toward Ponyville, but her heart soared up into the sky, flying high with delight and anticipation. As the library grew larger below her, Rainbow’s eyes narrowed, and she grinned. She couldn’t wait to explore more of the possibilities of potions.
