Some Combustible Lemons

You had always had a thing for unicorn mares.

The one in front of your pressed every button you had. Haughty, with a brilliant white coat and sapphire eyes, she stood before you, demanding and receiving your undivided attention.

"Hello, big boy," she purred, fluttering her eyelashes, "my friend and I will be requiring your services in a most challenging and dangerous affair."

Her friend, a purple unicorn, gave you a sweet look, blushed, and hissed to her alabaster companion, "Rarity! If you ask him like that, he'll think you're propositioning him!"

She smiled and whispered perfectly audibly, "Who's to say I'm not, darling?"

Her friend rolled her eyes and shrugged.

It was a forgone conclusion that you'd take the job, even if it was just hauling a cart through dangerous country.

As it turned out, this was exactly what the girls needed from you. Their goal was a magical cavern on the far side of the Whitetail Forest, at the bottom of the Misty Gorge, a mountain-sized geode known as the Depths of Desire. The first stop was Rarity's shop, the Carousel Boutique. You arrived promptly at the appointed time with your wagon.

She was waiting out front, impatient, standing next to a huge pile of trunks and suitcases and what appeared to be a traveling garment rack. She smiled sweetly and gestured towards her luggage. "Good morning! Be a dear and load this into your wagon."

You lowered the ramp on the back of your wagon and started pushing the heavy trunks as her friend arrived in a flash of magenta light. She looked at Rarity's baggage and remarked, "Gee, Rarity -- what do you need all this stuff for?"

"Now, dear -- we're going to be out in the wilderness. Every comfort helps, and there's no reason I shouldn't look my best." She winked saucily at you as she finished her sentence.

You hoped she couldn't see you blush. You decided it was wisest to concentrate on getting all her luggage into the back of your wagon.

Her purple friend scrunched her face, and a pair of large trunks popped next to her in a flash of light. You tried to shift one of them, but it was astoundingly heavy. "Wait a minute," the purple unicorn said as she retrieved a scroll from her saddlebags. "I want to double-check that I didn't forget anything important."

The heavy trunk's lid popped open, and you saw it was filled with books. The purple unicorn carefully inspected the contents, checking her list. "Let's see, Perilous Places, Volumes one through thirty -- check! An Annotated Atlas of All Equestria -- check! Oh! Princess Luna's Secret Garden!" She blushed. "What's that doing in there?"

You could feel Rarity's glare bore into the back of your head. "Twilight Sparkle...."

"What? It's a seminal work of ancient Equestrian erotic poetry." Twilight smirked at you. "Princess Luna had quite the imagination when she was younger. I've been working on translating it to modern vernacular to make it more accessible."

You turned to her other trunk, but she shooed you away. "Let me handle that. There's delicate equipment in there, like my telescope, sextant, compass, mineral assay kit, and star charts... oh dear, where did I put the star charts?" She stuck her head into the trunk filled with books. "I'd prefer you let me load it myself."

Rarity appeared mollified as you trotted back to her. "Give her a while. She's a dear friend, but once she gets started with her check-lists, she just can't stop."

Rarity was right, too. It took her little purple friend half an hour until she had run through everything -- twice. She then plopped her little purple butt on the ground and lifted her chin with a satisfied smirk. "Got everything!"

You moved to help her, but her horn glowed magenta, and the two heavy trunks floated weightlessly into the back of the cart. You cringed as she released her grip and you heard wood strain beneath the weight.

Fortunately, your wagon was up to the task. The girls clambered on board, and you engaged your harness and began to pull. Your hooves dug in deep as you pulled the wagon forwards, but momentum was your friend.

The roads out of Ponyville were in good shape, the sun was shining, and the clip-clop rhythm of your hooves drove you on. Pulling loads was relaxing, and once you got the wagon moving it was easy to fall into routine. You flicked your ears back to listen to the girls talk.

"Rarity, one of us needs to watch where we're going. You're just staring at his--"

"Darling, everypony thinks attractive mares only talk about sex," Rarity interrupted. "If we're going fall into this dreadful stereotype, let's fall in style. How's the tutoring with Applejack coming along?" The tone of her voice was saucy.

"She's an excellent student! We've already started--"

"That's not what I meant," purred Rarity wickedly. "Is she?"

The tone of her voice was enough to make you suddenly aware of your stallion parts. You hoped Rarity wasn't looking at that.

Twilight sounded a little embarrassed. "I value her too much as a friend to come on too strong. I'm not even sure she notices."

"Oh, of course she notices. I think she's just jealous of Rainbow Dash." Rarity seemed to be enjoying this.

Twilight let out an embarrassed squeak. "Well... Rainbow Dash is pretty awesome..."

"And awesomely pretty. A diamond in the rough."

"Well, we have fooled around a little, but..." Twilight sounded sad. "...when I supervised her and Big Macintosh running on that treadmill, I thought I was going to melt."

"If I were a naughty, naughty pony," Rarity opined, "I would see if I could use the rivalry between her and Applejack to your advantage."

"Rarity, that's dreadful!" Twilight sounded shocked and intrigued.

This was going to be a long, hard trip.

You took a break in the late afternoon, and cooled yourself down in a cold stream. You'd make the edge of the Whitetail Forest by sun-down. The girls picnicked, munching on daisy sandwiches wrapped in colorful napkins. Refreshed, you stopped to graze on some tall grass.

As you returned, Rarity was carefully folding the blanket. She looked up at you and smiled brightly. "Twilight! He's back!"

Twilight Sparkle trotted out from behind the wagon. You struggled to maintain a blank expression.

She was wearing a harness and smiling brightly. Her voice dripped with helpful innocence.

"I thought you might want some help pulling the wagon. We've made excellent time, and you've been working so hard!"

"Twilight... Sparkle...." Rarity hissed icily.

You couldn't help but smile. Rarity stared daggers at you, but you agreed.

Twilight used her horn to help you get started, and easily fell into your rhythm. She was in remarkably good shape for a scholar, and appeared to be familiar with the geography, geology, flora, and fauna of the plains, and spoke animatedly as you trotted next to her on the increasingly rough road.

Sometimes she would ask you questions, and you told her a few stories about the plains and the Whitetail Forest. She seemed sincerely interested, and you realized that she didn't mean to come off as a know-it-all, that this was an expression of her thirst for knowledge and not an attempt to impress or intimidate you. Talking to her made you feel smart.

It also took your mind off the gorgeous white unicorn watching both of you intently from the wagon.

You made camp at the edge of the Whitetail Forest. You had a moment to relax with the girls as the sun went down. Twilight seemed to be excited about something. You felt a little awkward. It was hard to talk to them, and they were both so friendly.

A few hours later, Twilight trotted away from the camp site, carrying her telescope in her glowing magenta grip. "Are you sure you two don't want to come along? This occlusion only happens once a century!"

"I'm sure we'll be fine," purred Rarity. She smirked at you sweetly as Twilight disappeared into the woods.

Rarity snuggled up to you next to the camp fire. Her white coat was tinted orange by the flickering flames. Her flanks were warm and soft.

"Oh, this is lovely." You had to agree. The warmth of her body and the smell of her perfume made you nervous and aroused. "You feel tense, dear."

She looked at you, eyes half open, then turned her gaze away, looking downcast.

"You must think me a terrible tease," Rarity pouted.

You didn't know what to say. She was teasing you, you could feel your cock threatening to get hard. It had been like this the whole day, and it made it hard to talk to her.

She looked you in the eye, bit her lower lip, and nuzzled you gently beneath your ear, pressing her white warmth against your side. Lust surged inside you and your heart raced as she gently nibbled and licked your ear. She whispered, "I don't just tease, darling..."

She pushed gently and you rolled over. Your cock, fully extended, erect, and throbbing, swung into view. Rarity covered her mouth with her hoof and blushed. Her giggle was sweet, too sweet for you to feel like she was mocking you. "Oh my, you're in quite a state."

Her pink tongue slid out of her alabaster mouth and slowly licked the length of your shaft. She was slow and deliberate, gently probing the bottom of your cock with the tip of her tongue, lingering a little at the end, before popping the tip into her mouth. She took you inside her mouth slowly, and you felt her tongue pressing against you as she lowered her head to your belly. She nuzzled your belly with your dick in her mouth, her tongue stroking its shaft, and then her head began bobbing up and down.

You saw her cheeks redden beneath her white coat, and saw her squeeze her rear legs together and writhe. You could smell a hint of her musk in the air. Her head bobbed faster, and you moaned, provoking a soft moan from her as well. As she lifted her head, she looked at you with half-open sapphire eyes and broke into a broad smile, the tip of your cock still in her mouth.

Her horn glowed, and you felt her magical grip gently fondle your balls. She popped your cock out of her mouth with a kiss on the tip. "You're about to... oh my... well, I won't leave you waiting."

Opening her mouth, she took you inside her again, and her head began bobbing frantically as she massaged your testicles. Your forehoof scratched the ground and you gasped for breath. It didn't take long for your excitement to peak. You tried to tell her you were coming, but only managed a strangled moan.

She popped your cock out of her mouth with expert timing, and the cool night air on your wet shaft brought you over the edge. She nuzzled you between your cock and balls as you blew a remarkably large load that splattered on the stones surrounding the camp fire.

"Oh my... that was impressive."

You got up slowly and pushed toward her. Rarity kissed you, taking your tongue inside her mouth, wrestling you gently.

You pushed a little more, and Rarity rolled over on her back, rear legs spread. Her marehood was in full blossom, and her musk made you dizzy. You slowly dragged your tongue down her toned belly, to the top of her swollen pink slit.

You circled her pink pearl before going down further, to probe between her moist, swollen inner lips. She tasted as good as she smelled. Her hole wasn't ready for your tongue, not yet.

She panted for breath as you went back up to her clitoris, circling around and crossing over gently, first slowly, then quicker as her moans became more intense.

Your cock was soon rock-hard again. Your tongue probed between her inner lips, and she opened, just a bit, to let the tip of your tongue inside her. "Oh, darling... please... now..."

She didn't need to ask you twice. You positioned your cock, and gently pushed the tip inside her. She was tight, but very wet, and you teased her a little with the tip of your dick, pushing slowly inwards as her pussy relaxed, taking your full length inside her.

Her warm wet walls grasped you firmly as you penetrated her. She closed her eyes and moaned.

Rarity began to buck against you as her excitement grew. She panted and moaned and you saw her belly subtly flush light pink. "Oh... my.... ohhh.... ohhhhh..." Her eyes were closed, her mouth open, her breathy moaning became deeper and more musical.

Her climax was a long fermata of "Ohhhhh!". Her pussy clenched as she squirmed beneath you, milking a few last drops of semen from your balls.

You held her beside the dying fire in the sweaty afterglow of your love-making. Rarity pressed against you and you nuzzled her behind her ear. "That was divine..." You couldn't disagree.

However, something was bothering you. Over the crackling of the camp fire and the rhythm of Rarity's breathing, you could swear you heard something scurrying in the bushes, sometimes even something that sounded like a muffled cry.

You excused yourself from Rarity and got up to take a look. As you got on your hooves, a flushed-looking Twilight Sparkle appeared in the shrubbery.

The blushing purple unicorn smiled awkwardly. "Oh... uh... I forgot my star charts..."

The next morning was nowhere near as embarrassing as you had feared. Twilight seemed to be stifling a giggle as she gave you a saucy wink. Rarity fussed over your harness as it came time to break camp, and gave you a playful nibble on the ear before boarding the wagon.

Officially, there was a road through the Whitetail Forest. In reality, it was more of a trail than anything else, passable for a wagon, but difficult going.

Overhanging branches forced the girls to dismount and walk beside you. Rarity made a point of rubbing her flank against you. Remembering the night before, your cock grew semi-erect.

You caught Twilight peeking at it once. She blushed sweetly, and decided to concentrate on her map. She would occasionally cast a glance sideways and nibble on her lower lip.

You were exhausted when the purple unicorn announced that it was only a short hike through the Misty Gorge until you would reach your goal. She found a clearing overlooking the canyon, and you took a much needed break.

You took a cool bath in a nearby stream, and Rarity came to you as you dried yourself off.

"Oh dear. We still have some daylight left, but you look to be in no shape to keep going."

She levitated a bottle of scented oil from her saddlebags. "Perhaps I can help."

The oil splashed on your sore back, and Rarity's fore-hooves began kneading your aching muscles, starting with your lower back. You heard a little splash of oil as she prepared to move up to your shoulders.

Her belly was slippery with oil as she climbed on top of you, almost mounting you, and she slid back and forth over your hips and flanks as she rubbed down your aching shoulders. She finished and lay on top of you, slick belly to back, slowly rocking back and forth, sometimes stopping to gently nibble your ear.

She whispered, "Feeling better?"

You did feel better, and while pulling a cart down a narrow, rocky canyon was not exactly what you wanted to do right now, you were quite prepared to soldier on.

Twilight Sparkle was at first surprised, and then amused as she smelled the scented oil that clung to you and Rarity. She offered to lower the wagon into the canyon with her horn, and you gratefully accepted.

Finding the mountain was easy, but finding the entrance to the caves was trickier. Twilight teleported to several different locations before calling you and Rarity to a cliff a little above the canyon floor. "It's over here!"

Rarity smiled, and levitated a pair of lanterns from the wagon as she nimbly climbed up to the cave entrance.

The shaft to the center of the geode was dank. The light from the lanterns sparkled off the facets of the crystals that coated the interior of the tunnel. Soon, all three of you saw the path widen before you as you reached the center.

The gemstone was gigantic. That was the only word that fit. A faceted sphere of sapphire the size of a pony caught the lights from Twilight's and Rarity's floating lamps.

Rarity's lower lip trembled as she slowly lowered her lantern to the floor of the cavern and released her magical grip.

"It's... beautiful..."

"Yes! I'm sure it will be perfect! Just the thing for the Princesses' state dinner with the King of Draconia!"

Rarity pouted. "Couldn't we find another gem for the Dragon Lords to eat? It's so beautiful...."

Rarity's lower lip trembled. "That beautiful hunk of rock even matches my eyes..."

You remained behind the girls, and were gazing lustfully at Rarity's graceful alabaster rump when you saw Rarity's pink slit flush and swell. She stared at the gem, seemingly hypnotized.

Her marehood trembled. "I cannot permit you to feed this glorious mineral Adonis to a bunch of scaly ruffians! It would be a crime! Against! Beauty!"

Twilight's horn glowed, and you saw a wave of magenta energy playfully slap against Rarity's elegant ass.

The purple unicorn's eyes widened as a tendril of energy slipped between Rarity's lower lips. Alarmed, Twilight cried, "Rarity?"

"You... you groped me!"

"I... I didn't know you reacted to gigantic gemstones like that! It was an acc --"

Twilight's apology was cut short as Rarity's horn ignited, and blue lightning danced over Twilight's purple haunches.

Twilight's legs buckled as she let out an involuntary moan. "Ohhhh... Rarity..."

Whatever Rarity was doing to her must have felt good. The cute purple unicorn blushed bright red as she rolled over on her side and began to writhe with pleasure. Her eyes were half closed as her horn also began to glow.

You saw as a long, thick purple shaft parted the moist lips of Rarity's vulva, thrusting deep inside the alabaster unicorn, spreading her open for you to see. Rarity moaned, and it was soon her turn to join her friend in writhing on the floor of the cavern.

The girls were fucking each other with magic dildos, moaning and panting as their solidified lusty intent pumped the other's sodden mare-hole. Heavy breathing and soft moans echoed in the cavern.

You and your erection watched, transfixed and flummoxed and throbbing.

Rarity lay her head on the ground, her haunches held high to accept the powerful pumping of Twilight's purple shaft. Rarity's back hooves were lifted a little off the cavern floor as Twilight's thrusts grew in intensity.

The cute purple unicorn rolled over on her back, spreading her back legs. Rarity's magic was tingling over a half-dozen sensitive spots, and Twilight arched her back as a blue spark probed her anus.

Evidently, that was enough to bring Twilight over the edge. As her pleasurable screams echoed in the cavern and her back arched, a gush of liquid spurted from her pussy. Rarity regained control as Twilight's magic member disappeared.

Moving slowly and carefully, Rarity lifted Twilight's harness from her saddlebags. Twilight protested weakly as the white unicorn roughly lashed her legs together with the thick leather straps.

"Rarity..." she gasped weakly, "you can't leave me like this..."

The alabaster unicorn did exactly that, leaving her friend struggling on the ground. Rarity's magic flared, pulling the stone from its resting place. Head held high, she began to head back out of the tunnel.

Ashamed and a little afraid of Rarity, you hid behind a crystalline stalagmite.

Your mother raised you to be a gentle-colt, and despite your erection and aching balls, Twilight's soft panting made you feel guilty about hiding and watching the girls... well, "fight" wasn't really the word for it. Watching Twilight struggle on the ground with her legs bound together was just too much to bear. You thought that maybe you should help her.

You were expecting her to glare at you. After all, here you were, much too late to help, and there was no way you could hide your boner. It took you a second to read the purple unicorn's face.

She was biting her lower lip and blushing. You realized she was looking directly at your throbbing member with a glint in her eye.

"Um... do you think you could... come over here?"

You approached gingerly as she struggled to roll over. Next thing you knew, her purple haunches were pointed at the ceiling, and her tail arched towards her head.

"You can't be --"

"Just do it already. Fuck me."

She was still sopping wet and loose from her "fight" with Rarity, and you sank balls deep into her. She moaned. "Oh, yes. Yes, please don't stop."

She could barely move as you began pumping her overheated hole, and was barely holding herself together. You slid yourself into and out of her, increasing the pace as she panted, "Yes! Yes! Yes! Yes- Yes- Yes- Yes- Yes!"

It didn't take her long to climax, and your aching balls were in no position to hold back any longer. You blew your load as you slid yourself deep inside her, and she grunted contentedly as she felt you fill her up.

She rolled over on her side and writhed a little. As your erection died down, you took a step to help her out of her fetters, when she suddenly disappeared in a flash of magenta light.

You gawked at the empty harness on the ground as she re-appeared beside you and gave your ear a gentle nibble.

"Mmm. Thanks, I really needed it." Her eyes traced a circle as she grinned smugly and said, "I could barely think all tied up like that."

Rarity had not only absconded with the gem, she had also taken the wagon, dumping Twilight's trunks to make room for the stone.

Twilight pouted. "Oh, Rarity... we'll see how far you get..."

An idea came to her, and she smiled wickedly and looked at you with a glimmer in her eyes. "Yes... I think I know the perfect way to slow her down." There was a decidedly lascivious tone to the purple unicorn's voice, and you were hardly surprised when her rump and tail lifted.

What did surprise you was the glowing of her horn and the swirling orange aura that obscured her hole. "It's a portal spell. I think you can guess where the I put the other portal."

She stuck out her tongue and blushed, wiggling her purple haunches invitingly. "I'm sure she's still pretty hot, but take it slow -- I don't want to hurt her."

Your skepticism disappeared as you the tip of your hard cock probed a tight, hot, and wet slit. It accepted the head of your shaft before closing tightly on you, which just made it even wetter.

Rarity's musk wafted through the portal. "How's she feeling?" Twilight asked, smirking wickedly.

Rarity' resistance was fading as you ventured deeper, eventually releasing a near gusher of hot unicorn juice as your shaft slid inside her. "Oh, I think she's ready," Twilight growled.

Twilight took over, bucking hard against you, forcing your full length into and out of Rarity's increasingly hot, wet cunt. You felt Rarity melt around your cock as Twilight increased the pace.

The scent of Twilight's musk intensified as she fucked her friend with your dick. A tiny spark appeared, burning at the base of Twilight's slit, and she bucked even harder against you until she had to stop to catch her breath.

"Pay attention, I think she's going to like this."

Twilight pushed her pretty purple ass towards you and began grinding, thrusting you deep inside her friend, twisting your cock inside her hot, slippery walls.

Rarity finally lost all resistance, and her pussy became a hot, wet, sloppy mess that you eagerly rutted. Twilight giggled as moans began to echo through the canyon.

"Go ahead and finish up. I don't think she'll be going anywhere anytime soon."

You eagerly complied. Twilight moaned as she presented her friend's pussy for your energetic rutting, rubbing her own clit vigorously. Her cheeks and hindquarters were flushed and sweaty, and you wondered if you or Twilight was going to cum first. The echoes of Rarity's moans of pleasure increased in pitch and frequency.

Twilight turned her head to look at you, her eyes slightly unfocused and shining.

A little later, you and Twilight made your way down the canyon, where you found a flushed, sweaty, blushing white unicorn panting on the ground. She weakly lifted her head and gave Twilight a dirty look.

"Twilight... Sparkle... you... depraved... pervert!" Rarity's lusty, flushed glare turned to you. "And you! Taking advantage of me in my... condition."

Rarity bit her lower lip and lowered her gaze. "Oh, I am sorry. I don't know what came into me..."

She looked again at you, lust in her eyes. "...well, except for you."

Apologies were made, and as you watched the unicorns embrace, you found yourself eagerly anticipating the trip back to Ponyville.
