After sending the Crusaders to the Friendship Castle, the unofficial base of Rainbow's harem, Rainbow herself went in search of more pussies to knock up and keep. She didn't currently have anyone in mind, deciding just to approach the next hot mare she saw. Flying above the town, she soon spotted Trixie's wagon and Starlight outside of it, seemingly waiting on her friend.

Rainbow grinned wide, her eyes flashing pink, and began to glide down to the wagon. She skidded to a stop in front of Starlight, turning a grin to her. As soon as their eyes locked, Starlight was immediately under her sway shown by the pinkish tint covering her eyes. She smiled at Rainbow, eyes unfocused, her pussy juicing itself up already.

"Oh, Rainbow Dash! It's great to see you, what do you need?" Starlight asked.

"Well, y'see, Trixie always seems to have a lot of fun with you on stage, and I thought maybe I'd ask if I could perform too?"

Trixie came trotting out of her wagon, pausing, eyes gaining the same pinkish sheen as everyone else. She blinked, before cocking her head. "You wish to be Trixie's extra assistant?"

"Nah, more like you two assist me. See, I wanna do a like, afterdark show. You know, more...adult. You can charge more for it too, Trix!"

The pair looked at each other, clearly considering it. They both nodded, and turned back to Rainbow. "The Great and Powerful Trixie accepts your offer to make her even more famous, Rainbow Dash!" Trixie said as she posed, before inviting them both in. "Come, tell us what magnificent show you have in mind!"

They entered, Rainbow chuckling as they imagined performing for the whole town, showing off her goods and inviting more ponies to be hers. She couldn't wait...

A good portion of Ponyville turned out for Trixie's Midnight AfterDark Spectacular, starring Rainbow Dash. It was sure to be one hell of a show if both Trixie and Dash collaborated, helped by Starlight's magic. No one wanted to miss it. The fact it was adult only and held in the middle of the night was a mysterious draw to the ponies too.

Trixie's wagon was in the middle of town, in front of the fountain, the stage set up and ready. It was bare, making ponies more curious about it. The only decoration was a banner declaring the shows name. They all sat in a semicircle around the stage, looking excited. No one paid attention to the odd mist swirling around their hooves, making cocks slide free and cunts juice up with as much excitement as the crowd.

Rainbow stepped through the curtain first, head held high, in socks on each leg. The ones on her hindlegs framed her pussy and sheath nicely, the rainbow pattern on them lit up by her artifact. She strutted around proudly, her wings erect and tail hiked up to everypony could see. The Artifact already worked it's magic, no one thinking it was odd to have a porno show in the middle of town, even if it was in the dead of night.

Trixie and Starlight joined her shortly after, letting her strut for a moment, wearing matching rainbow socks on all their legs. The pair also wore tall tail rings that held the tails up and showed off their privates at all times. They were both leaking down their legs, pussies wet and ready.

The pair turned, their backsides to the audience, glistening in the show lights. Rainbow strutted in between them, facing the crowd.

"Mares and gentlestallions, welcome! To the first ever Trixie's Midnight AfterDark Spectacular! A show I can guarantee you've never seen the likes of before!" Rainbow announced, the crowd stomping in applause.

"Tonight, you will see something brand new-Trixie as my assistant! Give a round for our gracious host," she joked, the crowd laughing and applauding again.

"Can everyone see my lovely assistants? Everyone can see how wet they are, how ready? Yes? Awesome. For our first act! Watch in amazement as my massive mare dick invades their foal holes!" she turned to the side, hoof up, her sheath on full display and her cock sliding out of it. The audience made oohing noises, some applauding at the show.

Rainbow mounted Trixie first, her fat cock rubbing against the magicians drooling wet hole. "Behold! As I impregnate my lovely assistant, live, on stage, for your clopping pleasure!" a few members were actually masturbating when they realized it was going to be a sex show. One or two were getting ready to mount another themselves.

Trixie and Rainbow spread wide, tails hiked, everything on display as Rainbow eased her cockhead against the throbbing, needy pussy. Trixie moaned, turning her head to make out with Starlight, adding a bit of lez to the show. Someone wolf whistled, and Starlight moved a hoof to her own genitals, parting her lips so the audience could see inside her slut hole while she rubbed her clit.

Rainbow popped inside Trixie's pussy, the crowd wide eyed and leaning in to watch. Trixie moaned, "Yes! Fuck me Rainbow Dash, impregnate the great Trixie! Knock up my powerful womb, right in front of a crowd!" she was drooling profusely down her hindlegs, apparently having had a voyeur fetish she'd been hiding.

"Damn right, you hot little tease, you love it when they can see my cock stretching you out, don't you? You want them to see the second you get knocked up!" Dash declared as she humped the magician, pussy juice churned up and spraying out around the penetration.

Trixie rolled her hips back onto the meat inside of her, panting in delight, Starlight now with her head on the ground, using both hooves to massage and hoof her own pussy. She watched her friends expression, enjoying it. Dash grinned, turning a bit, lifting Trixie's hind leg up into the air so the crowd got a good view of her pussy gobbling up Dash's girl cock. They could see every pop of her pussy lips over Dash's medial ring, every drop of moisture running down a vein.

Trixie rolled her hips back as best she could with one of her legs upright. The thrill of being watched, until she was impregnated no less! Kept her cunt gripping and rolling, massaging the welcome cock with each thrust. Everyone could see-see every thrust, every drip of pussy juice so they'd KNOW how much she loved this, what a nasty little slut she was, and the thoughts just made the puddle of precum and pussy juice grow around her hindleg still on the ground.

More than a few ponies were now mounting up or being mounted. Lyra and Bonbon were scissoring frantically in the front of the crowd, and the Cakes had stood on a bench so Mrs Cake could be mounted while they both had a good view of the action. Couples and strangers alike fell to the Artifact's general aura, all of them full of lust and no idea how to actually sate it. Those without or who couldn't find a partner did their best to sate themselves with a hoof, magic, or wing.

Rainbow grinned as she looked out over the crowd, her pink eyes glowing brightly even over the stage lights. She hooked her front legs under Trixie, letting go of her hind leg, and thrusting faster, Trixie's dirty talk now a random word salad of moans and encouragement. She tensed, moving her hips back, shivering in delight and effort as she raced to her own finish. She eyed the crowd, making eye contact with many of them.

"Yes! Watch me, everypony! Watch me be literally bred by this fine specimen, only the best cock for TrixIEEEEE!" She squealed, cumming hard, the front row of the crowd a splash zone. No one seemed to mind, many opening their mouths to taste and swallow it down or reaching a hoof out, using her squirt to lube themselves as they wanked.

"Here it cums! The climax of our first act, everypony!" Dash declared, holding Trixie's hips close to her, moaning as she spurted a large amount of foal batter into the fertile hole. She gave a few thrusts to pack it in, her own tainted cum splattering some ponies. Everypony that tasted it or put it on their genitals seemed to lose it, reaching Pinkie levels of random sluttery. Muzzles in pussies or assholes, suckling on dick or teat, it didn't matter. The show had become a massive orgy.

Dash pulled out, chuckling, Trixie collapsing to the stage floor. Her pussy was stretched wide open after their fucking, cum filling the space entirely and drooling down her legs. Starlight got to her hooves, picking up Trixie in her magic and moving her behind the curtain-Dash needed to be sure Trixie was pregnant with her foal before she got to slut around.

Once finished with her chore, Starlight trotted up to Dash at the front of the stage. "Everypony! If I may have your attention!" she called, everypony turning to look at her. Dash laid on her back, side to the audience. "Watch in amazement, as I make this massive cock vanish and reappear rapidly, right in front of your astonished eyes! You won't see an inch of this magnificent member, I guarantee it!"

The crowd cheered as she positioned her rear over the fat cock Rainbow held upright with her fore hooves. Starlight nestled her pussy against the tip, winking at the audience. "Here I cum!" she declared to laughter and delight.

She sat on the cock, the length quickly disappearing inside of her pussy. She shivered, cunt honey flowing freely around the deep penetration. She raised her hips, making it 'appear' before sitting down and 'disappearing' it again. She did it in quick succession, the crowd cheering her on. Rainbow grasped her hips, announcing, "Here's my surprise magic trick!" she grinned, raising her hips to meet Starlight's, and popped through her cervix to the pleasant warmth and grip of a currently unused womb. She fucked through it thoroughly, opening it wide.

Starlight cried out, and then moaned, rolling her hips to meet Rainbow's with each and every thrust. They met with wet smacks, splattering the audience even more. Starlight raised her tail, looping it around a foreleg, keeping it out of the way so they could see the penetration into her sloppy cunt. She wasn't into being watched like Trixie, but she had to admit she loved this.

Rainbow moved her hooves from Starlight's hips to her teats, pressing against them, feeling them up with a smile. They were very decent breasts, and Rainbow was very much looking forward to playing with them when they were heavy with milk for yet another of her foals. The thought had her gritting her teeth, rushing towards another orgasm. The Artifact ensured she could go as long or as often as she pleased, sending throbs of pleasure itself into her pussy-like if she was fucking herself like she was currently fucking Starlight.

Rainbow grasped Starlight tight, slamming her body down, and came in a rush of magical sperm, bloating Starlight's gut. Starlight trembled, the magic sperm in her womb making her hornier, wanting more cum. She didn't stop moving her hips, her pussy milking the fat cock inside her for every tiny spurt of semen. She only stopped-with a whine-when Dash herself pushed her off. Starlight grumbled, but trotted to the curtain, joining Trixie behind it, and the pair began to lick the cum out of each other.

Rainbow strutted back to the front of the stage. "This concludes the show part of the afterdark spectacular! If anyone wishes to meet my lovely assistants, you can join them behind the curtain in their cunt licking. As for me...I'll be taking applications for my harem all...night...long," she grinned, the Artifacts power enforcing her words. No one wanted to leave any more, each and every one regardless of gender or ability wanted her to breed them, feeling her warm cum surge up into their bodies. No one in town was immune, and after this town, no one in Equestria would be-and she had high aspirations.
