It's finally here: the biggest mail-order dildo money can buy. Flitter knows just who to try it out with.

This was written for Patches in Equestria as a part of Summer Sin 2021 story exchange!

Contains:  Twin sister/sister incest; public sex; unreasonably large strap-on cervical penetration; slightly rough sex.

This was a very different writing assignment, and somewhat outside my usual lane. However, I enjoyed this enough I wrote an author's notes blog post. Also, please consider reading Patches in Equestria's impressive Flitter's Friday, which is better than anything I have ever written.

Title suggested by Samey90; I can't believe it wasn't previously used in ten years of Fimfiction!

Put a bow on it

I had that day off work and slept in. I was barely out of bed, drinking my first cup of coffee, when my doorbell rang. My bow wasn't even in my hair yet.

Blearily, I opened the door. Gabby clawed over a large cardboard box. "Hi, Flitter! Imported from Griffonstone. I need you to sign the customs forms."

I squealed and flapped my wings. It was here! Six to eight weeks for delivery? Try eleven! So popular it had been backordered. Something vague tingled under my tail. I took Gabby's extended pen in my feathers and signed. Gabby tore off the bottom carbon sheet, waved a talon at me, and said "Have fun!" before flying away.

Looking at the customs form, I realized griffons didn't believe in discreet packaging: the shipper was listed as Birds, Bees, and Barbs Sex Toys and the contents as One 'Gallus' strap-on, size Extra-Extra-Large.

I rolled my eyes. Well, it didn't matter. It wasn't like I hadn't been in a threesome with Gabby before.

But, I knew exactly with whom I needed to break in my new toy. Glancing at the clock on my mantle, I saw we were coming up towards lunchtime. Perfect! I brushed my mane, put my bow in, cradled the box to my breast, and flew off toward Sweet Apple Acres.

The weather crew was building a large bank of clouds above the Apples' orchard. Sunshower Raindrops sat on a cloud above the others, supervising. Warm Front, Blossomforth, Clear Skies, and the others worked in two teams, circling in narrow orbits to condense water vapor into fluffy clouds.

And there, in the middle, wings flapping hard, powerful muscles straining under sweat-slicked fur, mane dripping from exertion, panting to move the multiton clouds and weave the magic that would force them into the rainstorms the Apples needed, was Cloudchaser.

I landed on a cloud and flattened myself down. My bow was too big and visible to hope to be inconspicuous, but none of them were looking in my direction. My tail raised and dampness—not from the cloud—built up underneath it.

The weather crew constructed clouds and brought them to Cloudchaser, then she melded them into the nimbostratus the Apples and the other farmers on that side of Ponyville had ordered from the weather bureau.

I reached my hoof down and played it across my clit as I watched Cloudchaser struggle and strain to move a dozen tons of water vapor, her flanks and chest knotted with the thick cords of muscle as she flapped and pressed with her forelegs, fighting the clouds into place. I rubbed myself desperately, the tingle in my clit spreading through my lower body. Even from fifty yards away, my own pegasus magic could sense how much effort Cloudchaser was putting in to cancel the clouds' inertia and get them into place. Sweat matted her mane down to her face and neck. Her tail sagged.

(That, of course, was why I had quit the weather patrol and gotten a nice desk job in the Hospital's records department. But she loves the outdoors and exercise.)

Cloudchaser shifted position, no longer working side-on to me, but coming around and pointing her rump at my vantage point. Her rear legs strained as she stood on one cloud to push another, her tail swishing and giving me glances under it...

My body shuddered and I gasped as I came, squirting prodigiously over the cloud I huddled on and soaking the underside of my tail. I sniffed and found I smelled like a whorehouse.

Perfect.

Gathering up the box again, I leaped into the air, flitted to where Cloudchaser was working so hard to build the nimbus clouds, and bucked the cloud she was hauling, evaporating it and wrecking her last fifteen minutes of work.

Face going instantly red, she shouted at me, "What the—Flitter! What are you doing? We've been working for hours and y—"

I turned around and wagged my whorehouse-smelling tail right in her face. She spluttered, stopping her rant in mid-syllable. Sunshower and the others zoomed down to where we were, abandoning their efforts in order to check on the commotion.

"I, was I naughty?" I asked. "I've misbehaved! You're going to need to show me the error of my ways."

Cloudy's voice dropped to a whisper. "Flitter, what the Tartarus? This is in public" —she pointed a hoof at Sunshower— "and my boss is watching!"

The other weather ponies settled onto a cloud above us, looking down, and Big Mac stood next to an apple tree, looking up.

"Like there's a pony in town who doesn't know about us," I said. "Heck, we've had threesomes with Mac or Warm Front in the past. And your boss caught us in the school bathroom way-back-when."

"Ugggh, worst day ever." Cloudchaser's face shifted from the red of fury to the pink of embarrassment. She dropped to a nearby cloud and stood, legs spread wide, wings tucked. "What's wrong with you, though? You wrecked all our hard work!"

"It's your lunchtime, isn't it?" I said, loudly.

"It is!" Sunshower called down. "Looks like we get a show with lunch, huh?"

Cloudchaser panted, hyperventilating, looking between me and her co-workers.

"Eeeyup," came from below us.

I craned my neck over the edge of the cloud and waved at Big Mac. He waved a hoof back, his eldritch abomination of an erection flopping under his barrel.

"Fl—Flitter," Cloudchaser said, "I'm afraid to ask what's in the box."

I tore it open, revealing the biggest insertable available for purchase anywhere in the world.

Cloudchaser's jaw dropped open, sweat from her bangs rolling down her cheeks, as she stared at it. After a moment, she read its name, "'The Gallus?' What does that even mean?"

"No clue."

The main part of the griffon-form dildo was blue, a foot and a half long, and terrifyingly huge in diameter, pointed and flared—and, best of all, barbed just like a griffon, too.

The other side end of the dildo curved up and around, bifurcating into two smaller flare-ended dildos, so that it could be anchored into the ass and pussy of the mare wielding it.

Cloudchaser's eyes ran up and down the huge—and hugely expensive—hunk of rubber, slowly gaging the intended use. "Are you serious?"

I bucked another cloud, destroying another ten minutes of her sweaty exertion. "I need to be taught a lesson."

She frowned, clearly angry, but her wings were getting stiff and her tail flagged high. I knew those signs meant I had her. I just needed to seal the deal.

"Turn around and I'll put it in you."

"Fine, if you promise to leave me alone and let me work after."

"Of course!"

Cloudchaser looked at the others. "You all are just gonna watch, then?"

They nodded. Warm Front gestured to his massive erection. "Unless you tag me in."

"Drop by my place tonight!" I said.

He winked and flicked his ears.

Cloudchaser turned around and raised her tail. I leaned in, sniffing her treasure box, which was strong with her sweat. I let the soft peach-fuzz of my snout brush across her clit as I breathed deep, luxuriating in the smell of the pony I loved most and had always been closest to. "Tonight," I whispered, "I can suck Warm Front's cum out of you." Her body shuddered, wings flapping, and her pussy winked at me. I leaned down and grabbed the back of the dildo in my teeth and lifted it from the box, lining up the two shorter, flared dildo-ends up with her two entrances.

I pressed forward and, true to the advertising copy in the catalog, the spells locked into the dildo's matrix self-lubricated the two ends—not that her pussy needed any help—and then slid in, locking into place.

She gasped and panted, a shiver running up her spine and her left-rear hoof spasmed, pounding the cloud several times. The top of her tail flicked my head and mussed my bow. The scent of her excitement waxed, overwhelming the scent of her exertion, and I licked up and down her labia and nibbled on her dock, which tasted of salty sweat.

I closed my eyes and sighed contentedly. The massive, intimidating hunk of rubber griffon hung under her barrel, puissant and stiff and oh my Luna I wanted it inside me so bad.

"Can we do this?" she said, frowning over her shoulder at me. "I still need to eat lunch."

I stood up straight and rested my chin on the base of her tail. "You know," I said, "I'm probably going to wreck more of your clouds. I'm so badly behaved. I think only some negative reinforcement will stop me from messing up more of your work after your lunch break is over."

Her eyes widened. "Wait, you want... want that in front of the others?" Her face went pale.

I stuck out my tongue and nodded. "I need to be taught a lesson."

"In. Public?"

I turned around and lowered my chin and chest to the clouds, down to my elbows, rump high in the air. My tail raised and shifted left, out of the way, and I felt all the pairs of eyes on my pussy. I clenched, the motion I knew made my asshole wink, and heard the slap of Warm Front's jumping cock against his underside.

Cloudchaser's face was turning red again. Her eyes went from embarrassed-wide to angry-narrowed and she smacked me across the rump with a wing. Wings aren't that solid, of course, but she'd concentrated a fair portion of her magic into it and the sting ran up my spine and left a nice tingle in my head. "A spanking isn't going to suffice, this time," I said.

She swept my back legs out from under me. My belly flopped to the cloud and I was now lying prostrate. Her forehooves then landed on my spine and slid down, forcing my wings to flare and she dropped onto them, pinning me to the cloud. Pain flared up my wings and into my body and I moaned as another orgasm hit me, my pussy squirting once more. She shifted her weight and the pain of a plucked primary feather stung my right wing.

"Yeah, that's pegasus punishment," I growled.

She ground her hooves down and the pain doubled. Tears formed in my eyes and I panted, biting down on the cloud, as my pussy throbbed, begging to get filled. The tip of the massive griffon dong brushed against my lips and then Cloudchaser rammed her hips forward, jamming it into me in an instant, piledriving the pointed tip into my cervix. Teeth clamped around my left ear, biting so hard it yanked my head and neck up as she pushed down on my wings and hilted the huge dildo into me.

I'd ordered it because it was the biggest that money could buy, but—my Luna! Inside me, it felt unlike anything I could remember or imagine. The absolute fullness as it stretched out my lips, my opening, the whole length of my channel. My entire body seemed to be rearranging to make room for it.

The agony in my wings, the sharp pain in my ear, and the massive fullness of the giant dildo in my pussy all combined and I moaned. The pain made the wonder of the fullness even deeper, pain and pleasure contrasting and reinforcing each other as my pussy clenched hard. I came again, my wings trying to flap but absolutely pinned, my muscles nowhere close to strong enough to throw her off me. She shifted her weight, kneeling instead of standing on my wings so that her chest pressed down on my spine and her weight pressed my wings even more deeply into the springy surface of the cloud.

"Okay?" she whispered, releasing my ear. "Not too much?"

"More," I said.

"I don't want to hurt you."

"You're not. Pump that dildo."

Cloudchaser shifted her weight off my wings and licked my bruised ear. Her hot tongue sent another shiver down into me. It filled me and shot down my spine, another spasm of contractions through my belly clenching on the dildo. Luna, how I loved her, loved this. I've fucked most of Ponyville, but Cloudchasher is still my favorite lover, the one I can't live without. Cloudchaser won't admit it, but she's done the same, and always seems to come back to me, too.

As she shifted her hips backwards, the catlike spines up-and-down the massive rubber griffon meat engaged, raking the velvety insides of my pussy and I raised my head and howled at the pain. Sunshower and the others cheered. Clear Skies even flew across to our cloud and landed a few feet from me, staring into my eyes, and started rubbing herself off as she watched.

The prickling-scraping-rasping of the dildo barbs continued seemingly forever as Cloudchaser withdrew the enormous slab of rubber from me. My pussy throbbed and a forlorn moan escaped me, suddenly so empty. Once Cloudchaser had her hips withdrawn and only the tip rested between my labia, she bit my ear again and she shot her hips forward, smashing the pointed tip of the dildo into me once more.

I screamed. Cloudy Skies came, squirting all over her own tail and she masturbated to the show Cloudchaser and I were putting on.

Without even a delay, Cloudchaser yanked her hips back and the barbs raked my inside again. "Ouch!" I shouted.

"Still good?" she whispered into my damaged ear.

"Harder and faster."

"You're a weird one, sis." She slowly inserted herself, a tiny scootch at a time, letting the massive inches fill me gradually. I shook. Muscular contractions across my belly anticipated each hair's-breadth of insertion until I was shaking, my whole body in tremors like a pony caught in a blizzard, and every muscle in my belly trembled with anticipation.

Warm Front landed behind Cloudy Skies and hopped up, mounting her from behind and slowly inserted his cock into her ass as they both stared into my eyes. Luna, I always loved it when I kicked off an orgy! Watching Cloudy Skies's face—ears perking up, mouth widening into an O, wings flaring—as Warm Front filled her butt just made my own excitement burgeon even higher.

As Cloudchaser hilted, reaching full depth, I let my muscles relax and engaged in the practiced motions that grabbed the flared tip of the dildo and clenched it with my cervix. The motion was a bit different from grabbing a stallion that way, but it was close enough. I pulled the tip deep into my womb.

From somewhere below us, from the Apple's orchard, I heard a massive eeeyup and I noticed Blossomforth wasn't anywhere to be seen.

As I pulled the dildo deep into my womb, that gave us the last hoof's-width of insertion and Cloudchaser's vulva pressed against my rump, the dildo now entirely inside me.

"Yikes," she said. "That thing's huge and you took it like Celestia sucks down cake."

Closing my eyes, forehooves kneading the cloud, I found the right muscles inside me and tugged.

"Hey!" she shouted, as my pull pressed the two other ends of the dildo deeper into her. "Hey, do that again."

When I relaxed, the barbs along the shaft engaged, but the painful sensation was barely the brush of a feather compared to the wonder of the massive flare deep in my womb and the thick shaft clenched in my cervix. Every bit of me tingled and trembled with the sensation as Cloudchaser penetrated into my deepest, most intimate places. Sweat broke out along my brow and down my spine and I clenched again. Cloudchaser sighed with the sensation, her double-headed end of the dildo pressing into her ass and her pussy as I pulled my end deeper into me, then the two ends relaxing inside her when I relaxed.

I pulled again and she moaned we settled into a rhythm. She lowered her head to rest on mine and shifted her weight, lying on me, pressing me deeper into the cloud. We both flapped in time with my pulling and she hugged her forelegs tight around my shoulders, kissing my neck and the top of my head. Cloudy Skies and Warm Front buttfucked quietly just in front of us, or maybe they were being loud and my ears were just ringing from my own heartbeat thudding in them. Either way, as I pulled with my deepest muscles, Cloudchaser pressed her hips forward, gently, and we built a rhythm that led to a sensation like lava spreading from the point deep in my womb where the dildo's tip rested, spreading down my pussy like a flow from a volcano and then across my rump and up my body, filling me, until everything burned with the pleasure and then Cloudchaser screamed in my ear and her orgasm wet my backside, where her pubis pressed against me and her forelegs spasmed around my neck and then I came, too, my whole pussy and insides yanking on the dildo, desperately trying to pull it even farther in as I stiffened and my wings flared and I squirted pussy juice all over her and then... then, we both collapsed onto the cloud, spent.

Cloudy Skies and Warm Front stared at me, and I stared back at them, and he hilted her one last time, finishing deep inside her with a whinny.

Everypony cheered. "Best lunch break ever!" Sunshower called.

Cloudchaser kissed my ear. "I'm sorry. Anything hurt or just sore?"

"Don't be sorry," I said. "Pull out. Gently. Just sore."

She inched backwards. I covered my eyes with my forehooves. With the orgasm passed and the endorphins fading, the griffon dick barbs on the dildo hurt as she backed off me. My womb spasmed at the sudden emptiness. After a few seconds, I heard the schlurp sound of the dildo breaking contact with me and smelled my own aftersex. Warm Front was just dismounting Cloudy Skies and the smell of their aftersex mixed in, too, leading to a wonderfully erotic melange that sent a last shiver down my spine to tingle my nethers.

Cloudchaser licked up my pussy, gathering my juices, and I found my body had one last teeny-tiny orgasm left. My feathers ruffled and then it passed, my body spent.

"All right," Cloudchaser said. "Get the monstrosity out of me."

I stood, shakily, and wandered around behind her. Tail raised, she stood still. I admired her for a moment, the huge hunks of rubber spreading her vag wide and leaving her asshole taut and puckered, everything slick with pussy juice. I bit the dildo's end and gently pulled it, closing my eyes and enjoying the scent of her aftersex, luxuriating in the olfactory proof I'd done my job well.

With a thunk, I dropped the massive hunk of rubber back in the box.

Cloudchaser kissed me on the nose. "Take that to your place and wash it. You can try it on me tonight."
