Rainbow Dash's Stiffest Wingboner

Rainbow Dash shredded cloud after cloud as she tore through the sky at lightning speed. Her stomach gave a defiant growl when she punched a hole in her twelfth cloud. She had flown all morning, and well into the afternoon, without pause. Her stomach rumbled again. She came to a halt and hovered high above Ponyville.

“I think that's enough flying for one day,” she said, surveying the land below her. Her eyes focused upon Sweet Apple Acres. “Yeah, I think I've earned this.”

Nodding, she hurtled toward the farm. Her mouth began to water at the prospect of biting into one of her friend's various apple concoctions. As she drew closer, she gazed longingly at the fruit-laden apple trees scrolling beneath. The prospect of giving in to temptation and sinking her teeth into a raw apple instead of waiting grew more appetizing by the second.

“No, it'll taste better if I wait.”

Within moments, she touched down next to the barn.

“She's gotta be on her lunch break or something,” said Rainbow, “that must be why she wasn't in the fields. Maybe she's in here.”

She took a step forward and her tail slapped against her flank.

“Ugh, darn mosquitoes!” She wiped her sweaty forehead with a hoof. “Part of me will be glad when summer's over.”

An unearthly scream pierced the air, making her jump ten feet. She landed, panting heavily as she clutched her chest.

“It sounded like it came from the barn!”

She approached it when she had fully recovered. She pressed an ear to the door and heard a steady stream of muffled moans. Gulping, she opened the door as far as she dared. A narrow beam of sunlight shone through the crack. Rainbow peered inside.

“Oh, ponyfeathers!”

The light revealed Applejack laying on a bail of hay. She moaned through a bridle and gag. Behind her, Rainbow beheld Big Macintosh impaling her with his namesake. Before each thrust, he withdrew his stallion cock over a foot from his sister's hungry maregina – whilst leaving untold inches inside her – before hilting himself with a loud slap!

Rainbow's mouth fell open as she watched the scene play out before her eyes. Neither of the siblings seemed to notice their unexpected audience as Big Mac continued to pound away with reckless abandon. Applejack tilted her head back as pure ecstasy swept her away. Rainbow felt a well of heat, that had nothing to do with the humidity, blossom in her nethers. She reached out a forehoof to her rump and placed it between her tight blue marehood lips. She gasped when she felt how soggy her hoof became from the touch alone.

“My mind says no,” she whispered before glancing at her stiffly unfurled wings, “but my body says yes. Oh, Celestia, YES!”

Rainbow swirled a hoof around in the depths of her honey pot as pleasure coursed through her. She felt her foreleg becoming more drenched as her filly fluid issued forth. She bit her lower lip as Big Mac picked up his pace.

“No, you can't be getting close!” said Rainbow under her breath. “I'm not done yet!”

Big Mac disobeyed her unheard command. He closed his eyes, scrambled backward, and pulled out his jet black behemoth from his lover. Rainbow gasped and said, “Where in Equestria did she put all that?” as Big Mac issued a final grunt. Applejack rolled over to face her brother's turgid head before it unleashed a torrent of wet, sticky semen.

Applejack tore off her cum-soaked gag and lapped up as much of Big Mac's horsegasm as she could. They both jerked his massive shaft with their forehooves as it pulsed and sprayed wildly. A lot of his horse semen evaded his sister's incestuous mouth, and instead got everywhere else; her chest, the hay bed they lay on, her mane, her hat, and most of all, her face.

Once his ejaculation had at last subsided, and he opened his eyes once more, Big Mac exhaled. “You sure do make the morning harvest worth it.”

Applejack giggled and licked her lips, collecting a thick dollop of cum on her tongue. “Thanks to you, I don't need no lunch!”

“Eeyup.” He sighed with contentment. “Wait, AJ, did you leave the door open?”

Rainbow pulled her forehoof out of her clenching pussy lips with a wet pop. “Oh, horseapples!”

She turned and galloped off as quickly as her hooves would carry her, almost slipping on her rainbow juice-soaked forehoof. When she felt she was a safe distance from the barn, she tried to fly away. Her wings would not respond.

“W-what's going on?”

Rainbow placed a forehoof on her left wing and tried to move it. It did not budge. She tried her right and got an identical result. Her head pounded and her wings throbbed. Sweat covered her body as her exertions took their toll. Fatigue and unbridled mareousal hit her like a locomotive. She had no idea why her wings were too stiff to fly. She had gotten plenty of wingboners, but none like this.

One hoof fell in front of another as she willed herself to reach the Ponyville Hospital, but every step was more difficult than the last. She had cleared the orchard and her destination was in sight. Rainbow stood atop a hill. The hospital lay at the end of the valley that stretched fifty feet below her. As she took her first step downward, she felt the last of her strength leave her limbs. Exhausted and horny, she vaguely recalled tumbling down the hill before everything went black.

*

Stars filled Rainbow's eyes as she came to. It did not take long before the pain in her head and wings – and the ravenous hunger of her marehood – began to palpitate again. The room swam into focus as consciousness returned. She lay tucked into a bed with pristine white covers. A sunbeam shone across the bed through a gap in the blue curtains. The room was sparely furnished with wooden beds and matching bedside tables identical to hers.

“Oh, you're awake!”

The voice came from the open doorway. Its accent was exotic, and Rainbow was unable to place it. It belonged to a beautiful white mare with a medium-length purple mane. She balanced a tray of food on a forehoof and beamed at Rainbow as she approached. She set the tray down on the adjacent table.

“You'd better eat up and get your strength back,” she said, giving the tray a nudge.

“Who are –?”

The earth pony's cheeks reddened. “Oh, how rude of me! I am Doctor Panacea,” she said, nodding. “You're fortunate I found you when I did, oh yes,” – Rainbow's eyes darted to her flank, which bore a stethoscope – “and if you follow Doctor's orders, you will be... ahem... 'relieved' in no time!”

Rainbow's wings gave a painful throb. Panacea's unique accent was driving her wild. “O-orders?”

Panacea's eyes, which matched her mane, stared into Rainbow's. “Oh, yes,” she purred. “I have encountered your condition in both pegasus mares and stallions numerous times. I know precisely the treatment you require.”

Rainbow scratched her head. “Condition?”

“You have never experienced this before?” said Panacea, sitting down and placing her forehooves on the bedside. “It is quite common in young adult pegasi, I assure you. At your age, hormones are coursing through your body like the rapids. Sometimes, a pegasus will become so stimulated that they are sent into overdrive.”

She lifted the covers and ran her hooves along Rainbow's left wing, prompting her to involuntarily shiver. “Your wings have been diamond-hard since I found you laying unconscious at the bottom of the hill four hours ago.”

Rainbow bolted upright. “You mean I've had this wingboner for four hours?”

Panacea gave her a soft smile. “Oh, yes, my dear. Not to worry; with my care and special treatment, you'll be right as the rainclouds you sleep on. Now, eat up while I prepare your treatment.”

Her words reminded Rainbow of her hunger's extent. She hummed with contentment as she delved muzzle-first into the bowl of hospital mush. Apples and cinnamon. She felt a hoof lightly touch her shoulder as she devoured it. In under a minute, the bowl was nearly clean, and she cracked an eye open. She nearly dropped the meal's remains.

Across the room, Panacea's curvaceous flank bobbed up and down, and her tail swished from side to side like a metronome. She was rummaging through a chest of drawers for something, but Rainbow paid no attention to what she pulled from them. Even from this distance, she could tell that Panacea's slit was slick with her fluids. Rainbow wolfed down what she could and cast the bowl aside before she plunged her forehooves into her aching pony pussy. Proof of her excitement had formed a small puddle on the bed.

“Oh my, eager to get started, are we?” Panacea turned around and winked.

Panacea's smile widened as Rainbow started to maresturbate. She stalked toward the bed, her movements catlike, before grabbing the bedsheets in her teeth and yanking them off in one fluid motion. Her tail dropped a couple of unknown objects at the foot of the bed before she clambered on top and stood over Rainbow.

“The first part of the procedure,” said Panacea, licking her lips, “is the oral examination. Would the patient kindly remove her hooves from my path?”

Unable to form words, Rainbow simply moaned and complied. Panacea closed her eyes and gave Rainbow one of her trademark heartwarming smiles before diving in, like a cat pouncing on a mouse. All of Rainbow's limbs quivered as she felt Panacea's muzzle bore into her foal garden as far as it would go.

Rainbow let out a long, guttural moan and she wrapped her hind legs around Panacea's head in an attempt to push her muzzle further in. Her pussy lips clenched on the muzzle between them as hard as they could. Every one of her nerve endings flared when she felt Panacea's tongue dancing inside of her, hitting all of her spots with surgical precision.

Her forehooves thrashed against the mattress as Panacea continued to help herself to Rainbow's unending banquet of pony love juice. Her eyes rolled into the back of her head as she felt her climax drawing nearer by the second. Her heart thundered in her chest and her breathing grew rapid and ragged as she neared her limit. She had never felt anything so good. Nopony's muff diving skill could hold a candle to the wonderful Panacea.

Every muscle in her body tensed up as she finally achieved horsegasm. Her broth washed over Panacea's muzzle as she was utterly overcome with pleasure. Time seemed to stop. She wanted to ride this high forever. Her lover's expert tongue continued to massage her g-spot as she eagerly lapped up Rainbow's fluids. She never wanted the Doctor's head to be anywhere but between her legs. She at last released her grip as she felt herself coming down. Panacea's face emerged from her maregina, looking as if nothing had happened – save for the juices dripping from her muzzle.

“You're – you're amazing!” said Rainbow. “I've never felt anything like it!”

“Oh, thank you!” said Panacea as she clambered atop her. “You sure know how to make a pony feel good.”

Before Rainbow knew what was happening, she found Panacea's muzzle making contact with her own. The taste of her own juices was overwhelming. She leaned into the kiss, her tongue passionately dancing with her lover's. Rainbow's hooves snaked around Panacea's back and made their way down until they found her rump. With one hoof, Rainbow groped her firm, yet supple flank. With the other, she massaged her waiting vagina.

Panacea deepened their kiss as she grinded against Rainbow's hoof, her hungry snatch devouring as much of it as it could. Rainbow worked her tongue inside her partner's mouth as if determined to explore every nook and cranny. She felt Panacea's nether lips begin to clench around her hoof. Sensing the Doctor's horsegasm fast approaching, she plunged her hoof in as far it could go and gave her a hard spank.

Panacea's eyes shot open as she abruptly broke the kiss and gave a loud whinny. She rocked her hips back and forth on Rainbow's hoof as she came almost as intensely as Rainbow had. Her tongue lolled out as her climax rocked her. She leaned down and gave Rainbow's muzzle an affectionate lick as she came down.

“N-now, my dear,” said Panacea with as much professionalism as she could manage, “we must examine your wings. How do they feel?”

Rainbow leaned forward and kissed her. She gave her tongue a brief suck before she turned to her wings. “No go.”

Panacea nibbled on Rainbow's left ear before dismounting the bed. “I thought as much; it usually takes multiple orgasms before the patient is fully relieved of their condition. I recall having to service a member of the Wonderbolts no less than four times before he was satisfied.”

Rainbow looked at her with awe. “Who? Who was it?”

“That,” said Panacea, playfully booping Rainbow on the snout, “is confidential.”

“I'll bet it was Soarin,” muttered Rainbow as Panacea turned her attention to the objects on the floor.

She resurfaced with an enormous pink double-ended dildo in her hooves and a bottle of lubricant in her teeth. She squeezed the bottle, and a generous dollop of lube coated the massive interhorse toy. After she set the toy on the bed and discarded the bottle, she began to spread the fluid around the shaft. It was thicker than one of their forelegs.

“What is that?” said Rainbow, gawking at it.

“The second part of the procedure, of course!”

Rainbow gulped. “But that's even bigger than Big Macintosh! That's gotta be at least –”

“About two feet, yes,” said Panacea matter-of-factly. “When I acquired it in Canterlot, I was assured that it is the Princess's favourite; presumably she enjoys all of it by herself. But not to worry, it comes equipped with two ends. We can use half each.”

Rainbow looked away. “But I don't know if I can... you see, I've never...”

Panacea cradled Rainbow's muzzle and turned her head toward hers. She leaned in and kissed Rainbow deeply. “I will be gentle at first, until you are used to it. Not to worry. A fully grown mare is more than capable of taking twelve inches at least. I have thoroughly studied anatomy. Why, some are able to handle almost twenty!”

“Okay, I trust you, Doctor.”

“Good, because this is my favourite part.”

Panacea sat on the bed and spread her lips wide with a hoof. With another, she grabbed the fake stallionhood and pressed it against her craving maregina. She moaned as she inserted inch after inch, shuddering from the shock waves of pleasure. A final whinny escaped her throat as her cunny devoured her half of the pink monstrosity.

She winked. “Now it's your turn. Spread your hind legs and do not move until it is all the way in. Doctor's orders!”

Looking like she was equipped with a phallus of her own, Panacea prowled toward Rainbow and leveled the other end of the dildo with her partner's foal garden. She mischievously bit her lip as she slid the lubricated tip past Rainbow's lips. Rainbow closed her eyes and exhaled as the thick rubber entered her.

Panacea continued her descent into Rainbow's love tunnel, one centimeter at a time, placing her hooves firmly on Rainbow's flanks as she guided herself in. Rainbow felt herself drawing closer to reaching her limit for the second time as Panacea delved deeper. She bit into a forehoof when two thirds of the shaft had penetrated her.

Panacea held true to her word; her pace remained slow, gentle, and constant, but Rainbow felt the last vestiges of self-control melting away as the dildo explored her aching abyss. Rainbow looked down. Only about two inches remained unsheathed. Feeling her final resistances snap, she circled her hind legs around Panacea's flank and lunged forward.

Gasping, Panacea fell flat on her back, and the rest of the phony phallus entered Rainbow. With an entire foot of hard shaft inside her, Rainbow's maregina lips gripped it like a vise and she came with the force of a sonic rainboom. Her vagina quivered as it felt not only the shaft, but Panacea's pussy. She leaned down and kissed the astonished Doctor, plunging her tongue in as deeply as it would go. Rainbow's tongue thrashed around wildly as Panacea paid her back in kind.

Rainbow moaned as she withdrew her mouth from Panacea's. “Where can I get one of these?”

Panacea giggled. “You are more than welcome to this one if you would like. I have a couple of spares in my personal collection.”

With every nerve ending in her love canal stimulated to the point of near unbearable pleasure, Rainbow gazed into the twin purple pools of Panacea's eyes, losing herself in them. “So... what next?”

Panacea pecked Rainbow on the muzzle several times. “Now – if you pardon my colloquialism – we horse around until you are spent,” she whispered between kisses.

Rainbow puffed her chest out. “Are you sure you can last that long? I'm quite the endurance flier, ya know!”

Panacea giggled and fondled Rainbow's flank. “Oh, yes, I am quite sure. This is a standard medical procedure, and I have had extensive training.”

Rainbow licked her lips. “Are you ready? You're just so darn cute, I don't think I can hold back any longer! I may get a little rough...”

Blood rushed to Panacea's face. “That is quite alright. Go as hard as you like; I am used to it.”

“Okay!”

Rainbow pulled up about ten inches before driving herself back down, prompting a whinny from both mares. A few thrusts later, she fell into a rhythm of pulling herself up as until her legs locked, and then pounding Panacea as hard as possible. A loud slap accompanied each thrust. Panacea's tail intertwined with Rainbow's as she lay spread-eagled, taking everything Rainbow had to give.

Covered in sweat and grunting from the strain of mercilessly pile-driving her partner, Rainbow only quickened her pace and put more power into it. She was so swept away in the heat of interhorse that she took no notice of Panacea, who had entered a state of unending horsegasm. The bed's springs squealed in protest to Rainbow's rapid slamming.

Finally, it was too much for Panacea. She wrapped her hind legs around Rainbow's rump during a downward thrust and held her in place as her climax reached fever pitch. Panacea cried out as she found herself paralyzed from pleasure.

Rainbow gazed down at her. “Done already? I thought you said you could take it!”

Panacea was too exhausted to offer a rebuttal.

“So, how much of this thing can you take, anyway?”

Easing herself into an upright position, Panacea blushed again. “Oh, only about seventeen inches.”

Rainbow pouted. “That's a lot. Anyway, are we done, or what? I can finish by myself; I think my wings are starting to work again, too!”

Panacea shook her head. “Oh, no, no, no. The procedure must be completed correctly. I always let my patients exhaust themselves before I have my turn.”

“Your... turn?”

Panacea's forehooves wrapped around Rainbow as she kissed her fiercely, guiding Rainbow onto her back. Rainbow, her vitality flagging, allowed herself to be swept away by her Doctor. Panacea worked her tongue with renewed vigour as Rainbow moaned into her muzzle.

When Panacea came up for air, her muzzle bore a wide grin. “Oh, yes! Now that you have loosened up, I am going to give you what I have got until you cannot walk straight for a week!”

Rainbow gulped as Panacea flipped her over with surprising strength. She felt her Doctor's forehooves on her back as she mounted up. Without warning, Panacea pulled her hips back and thrust them forward with incredible force. The whole bed rocked from the shock wave of the impact. Rainbow scarcely had time to recover before Panacea gave another thrust, and another.

Rainbow felt Panacea's hot breath on her neck as the Doctor pumped her hips harder and faster than she had before. Grabbing a nearby pillow, Rainbow stuffed it into her mouth to muffle her cries of pleasure as her foal garden was rapidly beset by the mammoth pink invader. The slapping of Panacea's crotch against Rainbow's flank became so rapid, the sound of the next slap reached her ears before its predecessor had left.

It was too much. Rainbow had not one ounce of strength left in her body. Everything had given way to pleasure. She climaxed in a crescendo of ecstasy. Throwing the pillow from her mouth, she let out a high-pitched scream until she felt her voice crack and give out, along with the rest of her body. She collapsed onto the bed, utterly spent, and her wings folded.

Giving one final, mighty thrust, Panacea at last loosened her maregina's grip on the dildo, allowing it to fall out of her pussy with a loud pop. She pressed a hoof against the exposed head, pushing the toy into Rainbow as far as it would go. She let out a sharp gasp.

“It looks like only six inches remain!” she said. “You truly are one remarkable patient, Rainbow Dash.”

“I-is the procedure complete?” she moaned.

Panacea patted Rainbow's folded wings. “Oh, yes, it definitely is. As promised, you may keep the medical device. Here, allow me to repackage it for you.”

She grabbed the shaft with both forehooves, planted a hind leg against Rainbow's moist flank, and pulled with the air of one drawing Excalibur from its stony prison. Rainbow's nether lips gave a thankful quiver as the head was removed. Panacea leaned in and gave her vagina a soft kiss.

“That will make it feel all better.”

“T-thanks, Doctor Panacea,” painted Rainbow.

Panacea set about toweling off the dildo before placing back in its case, along with the lube. “If you ever go into relapse, you know just the pony to talk to!”

“Best treatment ever!” mumbled Rainbow before blissfully passing out.
