Purple Proboscis

Shining Armor sat on Twilight's couch in the living room. It was after sunset, the clock just passing 8:00 P.M.

"Thanks for letting me stay here for now, Twily. I had a lot of fun today."

"Don't worry about it, brother. We haven't been able to catch up with each other for so long."

"Now I have to ask you.. if there anything else particularly special that you want for your birthday?"

"Kinda late to ask that, isn't it sis? Besides, I have everything I could ever need. I've got a wife who loves me and a sister who cares about me."

"Well no, I mean like something you REALLY want but can never have."

Twilight leaned seductively towards him.

"Are you sure about that? Because I think you want something else."

Wait, what?! Is she... No way.

He scooted back on the couch.

Twilight could sense his uneasiness.

Shining's mind raced, his heart skipped a beat, wondering what had gotten into his sister.

"Oh Shining, you're so overreactive to everything. If I really wanted to do that I would be wearing Cadences's thigh high socks that I know you love so much.'

As smart as her brother was, he was very bad at reading other ponies' body language, which made it all the more fun to tease him.

"Oh... Haha."

"Oh, stop worrying. I just thought that since it's your birthday and I haven't seen you in such a long time, maybe I could give you something more special than a gift I can buy at the store. I'm sure there are other things you want more than any amount of money could buy."

"So Shining, what kind of... sexual desires do you have?"

"Twily, it's not something I feel comfortable talking about right now."

"Why not? Shining, you're a full grown Stallion. We've been close our whole lives but you never discuss anything, well, intimate with me. I'm just curious, really it's not going to kill you to talk about it. Loosen up."

"It's ironic to hear that coming from you, Twily."

Sigh

"True, but I've learned a lot in the past years Shining. Keeping secrets to yourself your whole life just isn't healthy. Don't you think it would be fun to openly discuss them for once?"

"It's just not something that I'm comfortable sharing with anypony. Just give it a rest Twilight."

"Would you reconsider if I divulge my kinks first? Yours is probably more normal than you think, Shining."

"Uhm... Twilight, just don't. You don't need to tell me this stuff."

"You know, for a big strong stallion, your afraid of some pretty trivial things."

"Don't pull that card on me, it's not about being strong. Why do you have to push everything? Learn to take no for an answer, Twilight."

"If you won't tell me, then I'll just have to start guessing."

"Well ok then. If you insist on wasting your time then go right ahead."

"Is it another pony besides Cadance"

"Oh for Celestia's sake, don't start this..."

"What about an object?"

"This is pointless, Twilight..."

"An animal perhaps."

"Twilight, cut it out! What would even make you think that, anyway?"

Twilight curled her lips.

"Nothing in particular. What I want to know is, why would you be curious about that? Unless of course I'm right."

"Is this something from one of your stupid equine psychology books?"

"You sound really uptight."

"What? No, I'm just irritated with you."

"Are you sure about that?"

"Sigh..."

"So what type of animal is it?"

"Ok, ok... I'll tell you, just promise to keep your mouth shut and don't bring this up around anypony else."

"Alright, sounds good."

There was a long silence. Shining merely shuffled in his seat, rotating his head around the living room and trying to pass time.

"Just tell me what you want to stick your dick in, jeez!"

Another short pause.

Sigh

"Well... Uh...

Shining paused.

"I've always kinda loved... You know..."

"Go on."

His breathing  and heart rate quickened. It was unavoidable at his point.

"Even if I told you, it's not exactly something that YOU could do... If that makes any sense."

Twilight elicited a chuckle.

"Oh, I see you've got a little fetish for somepony else?"

"No I mean that... it's just... not a p-pony that I want...."

Twilight's curiosity piqued.

"What, you mean like bestiality?"

Shining cringed internally at her objectiveness and utter straightforward thought.

"Would it help if I told you mine first?"

"Um, yeah sure."

Anything to stall the time and give him an opportunity to think it though.

"Shining, to be honest... You briefly mentioned your fetish years ago, don't you remember? We were staying up late just talking, getting to know each other more. I had asked you what your fetish was and you just gave me two words. What did the first one start with again, I think it was an "E"?

"But then why are you asking me?"

"No reason.. I just want to hear you describe it again. In as much detail as possible. Plus you never explained it very much and fell asleep on me. I want to hear the rest."

"Come on, Twily.."

"Well you do want it don't you? Besides, how can I do it exactly the way you want if you refuse to elaborate? Tell me why it makes your pee pee go doing."

"I hate when you say that."

"I know, silly."

"And that doesn't explain how you'll be able to do it."

"You seem to forget about the horns on our heads. I've got spells for anything you need."

Shining sighed, and took a long, deep breath.

"Alright..."

Another pause. He mentally prepared the sentence in his head, to be as clear as possible. He didn't want to have to repeat himself.

"I want to have an Elephant suck my penis with it's trunk. I-It's like... you know..."

Shining reeled, wondering how he could ever say that. Twilight's interest piqued, so he continued, unwilling to drag it out longer than necessary. Anything to get it over with.

"I mean their trunks are so dexterous, and they're like vacuum cleaners... Their nostrils are as wide as pool balls so it would be a perfect fit. "

A sudden conflicting wave of both embarresment and relief flooded over him. This had been a fetish of his all his life, never had he admitted it directly to anypony. Not even his own sister.

"So big brother, when exactly did you 'discover' this longing to blitzkrieg your dick up an elephant's giant snozz?"

"So yeah, that's when it kinda... clicked, I guess? That's the closest you can get to a natural milking machine. I just suddenly though about how incredible it felt. It's like a leathery vacuum hose, but no so much suction that it hurts. It had just drank a lot so the trunk was really moist, and was relatively clean. I just started thinking like... How amazing would that feel if it sucked my dick dry with that thing? Sadly, I had to stave off the though because I was in public. We eventually left, and the exhibit moved to another city the next day. It comes back once a year, but I can't risk going to see that anymore... Not when I can't even look a picture of an Elephant without getting a giant, raging boner, let alone a real, breathing one."

Twilight giggled at his crudity.

"So, how do you ever plan to... accomplish this?"

"I really don't know Twily... It's not like I can just walk in there and be like, 'Hey zookeeper, can I have some alone time with your Elephant? I want to fuck it in the trunk. And make sure it's a female one too!"

Twilight was elated to see that he had loosened up enough to say it in such a lighthearted way. It was exactly as she had hoped.

"So... What would you say if I told you that there's this spell..."

A strange feeling pieced his mind, he let her continue.

"That let's me grow appendages specific to other animals. Any animal. Would that be something you'll want to try?"

"A- what.. A-are you serious? Like you can actually give yourself a trunk a-a-and-"

"Yes brother, I sure can. I can suck you allllllll night if you want."

Shining felt a strange relief emanating from his very soul.

"Twilight, this is just... this has eluded me my entire life. You can't fathom how much this will mean to me."

"Oh, don't worry about it. I think this will be fun for the both of us. Also, it's nice to see your ramping up your vocabulary; guess your fetish brings out a whole new side of you."

"Heh, being around you all day it would be impossible to not learn something new here and there."

Twilight cracked a smile.

"Thank you Twilight."

"Don't thank me yet, save that for when I'm probing your penis with my proboscis."

Shining felt like he should know what that meant, but he was nonetheless perplexed.

"Um... I'm guessing that's, uh.. just science talk for-"

"Sucking your big stallion wee-wee with my trunk."

"Heh... learning can be fun somethimes..."

"And then milking you for all your cum as I throttle it within my nostrils and inhale-"

"ALRIGHT, please stop, don't ruin the mood for me..."

"Oh please, you could do push ups with your boner right now."

Shining shamelessly glanced down between his legs.

"Ughhh... how long will the transformation take?"

"Not long. I've done it before."

"Wait, what? When?"

"Now it looks like it's my turn to tell you a story."

"Uh, can this wait?"

"Nope, too late. It's short though, I promise."

"Fine."

"One of Celestia's assignment a while back was to practice transformation spells for a big exam. At that point I had the basics down pat, but the exam was pretty extensive. She was expecting me to be prepared for anything. So for a whole day straight I flipped though a book of animals, trying to accurately transform into as many as I could, sometimes giving myself specific appendages to tighten my accuracy. Eventually, I got around to Elephants and tried giving myself a trunk. I spend a few minutes getting used to it, just because it was fun to use. But I was alone in the library. Let's just say that their trunks are indeed... dexterous. And I can assure you, with a good deep breath the suction is pretttty great."

Shining's mind was suddenly filled with disturbing, yet erotic thoughts.

"My point it, I've had lots of practice with it if that's what your worried about."

"So, um... that weird slurping sound I heard coming from your room last night..."

"Yep."

"Or maybe that was Spike getting a little something."

"What!?"

"I'm just pulling your leg. Nobody else knows about it."

"Can you describe it now?"

"Enough describing, brother. I can show all of it to you. Stand back."

A low hum filled the air as Twilight channeled energy into up her horn.

The room lit up with a blinding white light. When the overwhelming light subsided, Shining nearly fainted. It was exactly as he had imagined. His pulse quicked and his breaths shortened as his eyes adjusted to see Twilight in full clarity with a long, purple trunk dangling in front of her where her muzzle used to be. Her mouth had shifted south. Her face had slightly altered shape to be bulkier and support the heavy appendage attached there.

"Does it work?"

Twilight responded with a Facehoof. She lifted her trunk up like a periscope, curving into an S shape with the nostrils facing towards him. It felt so strange to have this so close to him. She took a deep breath and inhaled. The room was quite, so he could hear the air rushing through her nasal passages.

She set a bucket in front of him and filled it with a gallon of water. She dipped her trunk below the surface, and sucked up every drop. She dragged it around the edges, pulling in every last drop with ease.

Twilight trotted over and casually sat up straight on the couch next to him. She wrapped her trunk around his belly and let the tip come to rest on his chest, gently stroking at the furry skin with the tip. She pulled him closer. The single finger-like lip curled and stroked. Shining could hear the deep huffs of her breathing.

"Enough teasing Twilight, let's get to business."

Twilight pushed her trunk up against her vagina and gave it a little rub until she was turned on.

Twilight goes to the bathroom and swished water through her trunk before starting so it is soft and moist. She returned, and curled her trunk seductively as she kneeled down in front of him.

She lifted it directly in front of his muzzle, giving him time to collect a good view. It was strange seeing it so up close and personal. She edged it right in front of his eyes. Shining could see straight up the fleshy, pinkish interior, visibly noticing as her nostrils expanded and contracted slightly with her breathing. It was like a living, breathing vacuum hose. Her hot breath assaulted his face. She lowered her trunk and sucked in against his muzzle.

Shining took the opportunity to stick out his tongue, and probed deep into her nostril. It felt strangely like a mouth, except without another tongue to fight back. She tugged and suckled at his tongue, it felt amazing. The dexterity she possessed was unreal.

She let go, and wafted over to his left front hoof. She Stroked the fabric of the sock with the finger-like lips of her trunk. She placed her open nostril over the flat end of his hoof, and inhaled. The sock bunched up and lifted off his hoof.

Shhhhcccclluuucccckkkkkkkkkkk

Shining watched it dissappear into the darkness of her trunk with a "Fomp" sound. It was strangely arousing. She fired it out of her trunk across the room, and did the same to his left hoof.

The foreplay had made him achingly hard.

She withdrew it, and brought it back over his chest. She planted her nose forward, and with a quick "puck" sound, locked her nostrils to the skin of his chest. Her trunk felt like a moist, fleshy vacuum hose. She shifted her trunk slightly to give him another kiss, this time even more powerful, it felt powerful enough that he was afraid it would leave him a hickey. Shining quivered with nervous excitement as she tenderly rolled her trunk across his chest in a circular motion, stopping every few seconds to inhale a bit, leaving a small mark on his skin. It left a light trail of moisture wherever she touched. Twilight seemed excited too, as she deftly took in his scent.

She climbed over him, head over his crotch and trunk set forward, tip perpendicular to his skin. Shining felt a tinge of warm air pulsing in and out from her trunk in tandem with the rising and falling of her chest. Her every breath sent shivers though his body.

She lifted her trunk up to his horn and sniffed. Gingerly, she grasped it and massaged up and down. A sharp tinge of pleasure shot through his spine, the hyper-sensitive nerves in his horn hurting. Slowly, she moved to the top and fully enveloped his horn, creating a tight suction seal to his forehead. Shining felt a sharp pang of pleasure slice through his body as his horn began pulsing.  The magically energy emanating from him ran though to Twilight's body as well.

As though she could sense his want to move on from foreplay, Twilight slowly shuffled backwards on her knees. She slowed down as she neared his crotch. Shining was fully erect now, eagerly awaiting her. He could see that each nostril was wide enough to take in his whole stallionhood, as the anticipation took over is entire body, his cock fully erect and eager to be sucked.

"Hope you don't mind if I hold you down for a minute. Cuz' I'd sure like to get a whiff of your nice, juicy cock."

With a glowing of her horn, Shining's limbs were thrown back and pinned against the blanket, leaving him fully exposed. Twilight lifted her prehensile trunk into position over his erect member, snuffing and sniffing in circular motions near his tip, examining every inch with incredible precision. The warm, pulsing breath emanating from within her agile appendage was intoxicating.

"Ennnngggg... come on Twilight j-just do it! My balls feel like they're gonna explode!"

The though of Blitkrieging his dick up nature's most formidable nasal instrument was a frightening, yet strangely alluring prospect to him. Twilight paused for a brief moment. She sniffed and snuffed around his crotch, circling his raging boner with her trunk, brushing up against it numerous times to tease him.

Shining was now panting with desire, his body at the edge with no room for turning back. She finally lifted her trunk and positioned it directly above his penis. Pre-cum was dribbling out. She lowered until the tip of her nostril brushed against his head, and took a deep whiff. The rushing air encircled his member and Shining whimpered, his penis achingly stiff. His body shook and he tried to thrust his hips up, but was still restricted by her magic. Suddenly, she released her magical grip and expertly slammed her trunk down, swallowing his penis into her left nostril. She pushed down with a wet shluck sound until he was fully enveloped, creating a tight seal between the finger-like lips and the skin of his crotch. She clasped her fleshy nostril around his shaft, stroking him up and down. Shining could feel every ounce of blood in his body surging to his pelvis, the sensation nearly overwhelming him.

Twilight felt her loins growing wet from the experience. Watching her big, strong brother squirm in foalish delight as she pleasured him was highly arousing. An enormous smile plastered his face, front legs bending up and contracting. She had never witnessed her brother in the throes of sheer pleasure at this level, and it was a great feeling to see him this happy.

She repeatedly flexed and contracted her nostrils, all the while twisting her trunk and stroking up and down. She sucked with incredible precision, and the vigorousness of a milking machine. She possessed a rare, pleasing combination of dexterity and power. The vibrations caused from the space around his penis was amazing.

She looked him right in the eyes, evidently eager to suck away his load. The sensitive nerves in her trunk were on fire, and she could sense his raging hormones radiating through.

Twilight's heart rate quickened as her arousal increased. Her breathing accelerated, and Shining felt the heat within the confines of her nostril skyrocketing. The pulsing, intense heat combined with the fluid motion and incredible suction was too much for him to hold in any longer. He shivered as his load began to fly. Twilight tightened her grip on his shaft, just barely managing to hold it down as he spasmed, his hard penis throbbing as he pumped burst after burst up her nasal passage. She sucked with every breath she could muster until he was finished. She finished drawing the sticky liquid up, slid her trunk off and sealed her nostrils so it wouldn't spill on the floor. It made a slick sound as she pulled off his lubricated dick.

Shining panted as the shockwave of euphoria gradually subsided and his penis began to soften. He felt purged, and clean. Every ounce of pent up testosterone had been drained from his body, and he felt at ease. Starting to focus a bit more, he looked up from his dick to Twilight, still leaning over him with her seductive purple eyes, winking her lashes. She had a goofy smile plastered across her face.

"So, I take it you enjoyed that?."

"It was even better than in my fantasies, sis. So uh, how did that feel for you? Like when I-, I-"

"It felt incredible. You sure pack some gooood equipment, brother."

Her voiced trailed into a sexy undertone as she grinded her hips together.

"Now... we're not done here yet. You're going to return the favor. Hold still, this might feel a bit weird."

Oh man

Her horn light up glowing. A magical aura spiraled around it. Suddenly, it blasted straight at Shining's muzzle. He felt the skin expanding, until a tube began to form. Within 15 seconds the spell was complete, and a long, muscular trunk dangled from his face.

"Think you can learn to use this as fast as you came?"

Shining almost felt nervous at the prospect, but he had no choice. Twilight had given him exactly what he wanted and he couldn't leave her hanging.

"I want you to get a bucket of water, and show me that you can do this."

Shining successfully sucks up the water after a few tries.

Shining sucked her horn, feeling the leftover energy from the spell pulsing from her horn.

She laid back with her legs spread apart, showcasing her bulging clitoris. She curled her trunk up and stuck out the finger-lip, making a pointing motion between her legs.

Shining approached, hovering over her body. He brought his trunk down and began sucking at tufts of chest fuzz, circling her belly button. Finally, he placed his trunk near the opening of her marehood, exhaling slowly. Twilight shuddered in anticipation from the feeling of his tantalizing warm breath. She elicited a deep moan. With a swift motion, he sucked in deeply and rammed his trunk forward. There was a loud foomp sound as the suction selaed his trunk to her crotch, fully encircling her opening. He used his front hooves to pin down her legs, and began sucking more vigorously, rubbing circles around her marehood as he bended and twisted it like a snake.

"Eeeeeeeep! Huff, heauah- ennggg!"

Twilight quivered and squealed in ecstasy as her limbs locked up. It was as though every nerve in her body was paralyzed except down there. Warm juices were already beginning to leak. Shining rubbed harder, breathing deeper, pushing her to the edge. Shining started to realize how sensitive the trunk was. The sensitive skin started to feel warmer from her heightening arousal.

With hardly any warning, she erupted a stream of warm fluids and flooded his trunk. There was a loud sloshing as he could hear the juices being channeled up his wide nose. He struggled to suck away her cum as fast as it gushed out of her body, but managed to contain it with only mere drops escaping onto the blanket below. Her body shivered harder and harder as each wave was whisked away. She spasmed violently as the final purge came. Her body almost felt lighter.

Twilight seemed to relax, and he pulled away, folding over the finger-like lip of his nostril to pinch the trunk shut and keep her mare juices from running out. His trunk tingled from the heat the expounded juices were giving off, radiating outwards through the thick, sensitive skin. It felt like nearly a quart, weighing a considerable amount.

"Huff, haAAaaaa... Guh... Shining, your were incredible!"

"Who says we have to stop now?"

A sudden thought struck his head. He placed the tip of his trunk back over her clit, and blew outwards as hard as he could. Twilight screamed in pleasure. He proceeded to suck it back out, and started to exhale and inhale rapidly, alternating every few seconds. A pang shot through her lower body in her pelvis as the jet ripped through her. Twilight could feel her hormones recharging now, and see the bulge in her belly expanding out with every blast.

"Aaaagghghh, don't stop! This is a-am ama-aaahhh!!"

Twilight was overwhelmed. The sudden pang of it blasting into her like a fire hose and the sensation of it being pulled out again was incredible. The cacophony of slurping and sloshing became louder and faster. Shining had to pin her legs down extra hard to keep them from flailing dangerously.

"Aaaaaaaffghhg!"

Twilight nearly blacked out as her body exploded outwards a large new wave of cum. He sucked if all up and pinned his nostrils shut before finally pulling back. Twilight panted and heaved like she had just gotten back from a 10 mile trot.

Shining laid back and tilted his trunk upwards above his dick. He slowly opened and rammed himself inside. He did the same thing fo himself as he had to Twilight, until he shot a load in.

Sealing his trunk, it was bulging and very full. He went back to her side.

"Was that good enough, sis?"
