Assigned male drone Jeron: Attention ladies and gentlecolts and gryphons of all ages of adulthood… I know you’ve all been waiting for this moment, as many of us have, we have the commander experimenting with a gender change spell! Needless to say, this has not been successful in our world before and we are all eager to see just what the commander does with it.
… *ahem* anyway, please move along if for some strange reason you’re not interested. Questions? No? Good.

'Yes Legate.' The drone replied, pulling the book out from where Dawn had hidden it and relayed the details of an alleged gender change spell.

Dawn smiled as the instructions were given. "Interesting. I thought it would be more complicated."

Twilight blinked at that answer, not sure what to make of it.

Dawn relayed the five equations of mid-length from the text. "Not too complicated right? At least for you. I have memory retention issues."

'You shouldn't have memory issues anymore' the queen said in the link.

"That's mostly a spell for summoning a door." Stone blinked.

'You'd be surprised.' She replied to Chrysalis before looking at Stone with surprise, "Oh?"

"Yeah." Stone said. She ran through the spell and a wooden door in its frame appeared between them.

Dawn frowned, then tried to perform the spell herself, with Stone as the focus. It took a minute to compile everything together, but she could feel Stone's body shift as she continued to focus the spell until it was finally complete.

Stone blinked and looked between her back legs, but nothing was there that she could see, but she could tell something felt off.

"Uh…" Stone blinked as she looked at herself, then remembered to drop her illusion to her normal self. She was shocked to see a new set of genitals between her back legs, more than decently sized at that.

'Oh, I like!' the queen said approvingly, blatantly looking at her mate’s new appendage.

The Queen had such a look of hunger clear on her face that Dawn didn't need to feel the desire or arousal in the link to know what was on her mind. Her mind was still open to the link, and everything running through it about Twilight was very much not for public view.

Dawn bowed, locking the door to her room with her magic and shifted to her natural state, revealing the collar she still wore, "Is mistress satisfied?"

Twilight jumped from looking at her new member and looked at Dawn.

"Huh? What?" Twilight blinked.

'Oh you are evil or never satisfied. You really are my daughter!' Chrysalis praised.

'I aim to please, my mother,' she chuckled across the link, 'and live up to the changeling way of course.'

Dawn then spoke out loud, "It appears that there are some differences in the magic you know and use, and what I can use... perhaps, if you wish to use this spell later, I can have the book sent to you so the other me may cast it when you wish."

"Uhhh… sure. New spells are always nice." Twilight said, still blinking as the queen began to drop to her natural form and stood with Dawn, also wearing her collar.

'Seems we are making her hard very fast.' The queen said in the link as Twilight’s new member was already sliding out of its sheath.

'Good, after all, she would need to know if it works. Though personally, I wonder if she'll enjoy or hate the fact that she has balls as well like my issue was.' Dawn chuckled before replying, "As you wish."

'One thing I've learned about her is that she just likes sex and has wanted to see what it was like to mount someone with an actual penis.'

Twilight continued to be aroused as she looked between the mares, unaware of their conversation.

'Well, I'm sure you know, it is quite different, but still incredibly enjoyable.' She replied, before saying out loud, "Is mistress pleased? or would she rather be called Master in this state?"

"Huh? What?" Twilight shook her head, confused at what was being proposed.

"Is mistress pleased?" The queen asked. 'You go master, I go mistress and we hit her with both barrels!'

"Is Master pleased?" Dawn asked gingerly, trying to sound like she wanted approval.

"Um… uh…" Twilight stammered, reaching desperately out to Meadow as her mind raced and blood flowed to the new area, ‘Halp!’

'Uhm, w-we're hard…’ Meadow commented, sounding embarrassed, ‘Unless you rub it out or something, i-it's gonna take a while to go down. Maybe an hour.'

"Master… if you aren't happy with it, I can change it to suit how you wish." Dawn said submissively.

"What? Change it?" Twilight asked.

'Make it bigger!' The queen said excitedly.

'I have to be careful,' Dawn replied in the link, ‘I can't make it too big or out of place, or she'll lose too much blood, but perhaps one like an earth pony like Stalwart. Any requests for his balls?' She teased to Chrysalis.

'Y-you have to rub on it to cum and let it go down sooner…' Meadow said, 'D-don't make me repeat it please, I'm so embarrassed…'

'Oh yes, he was a nice size! And you can choose the size of her balls.' the queen said.

'I...what? You mean masturbate?' Twilight asked.

'Big enough to make a good slapping sound against our flanks it is.' Dawn chuckled lewdly to her queen. 'He ought to enjoy this.'

'Y-yeah...' Meadow said, 'J-just need some privacy.'

'Do it now while she's distracted~~' the queen said, practically drooling.

'Already done.' Dawn said, her horn glowing briefly as she grew those hanging orbs to the desired effect. 'Now they're slightly bigger than Stalwart's, fitting for an alicorn no?'

'Most definitely.'

Twilight gasped and moaned as she felt the growth, a spike of pleasure spreading through her lower parts in a tingling wave.

Dawn pined, hoping to appeal to Twilight's dominance as she said, "Is that better master?"

Twilight looked at her, licking her lips once as she seemed to study Dawn and Chrysalis hungrily.

'Present yourself!' The queen said in the link.

Dawn turned herself around and held her tail to the side toward Chrysalis, Chrysalis doing similarly with her own body and draping her tail over Dawn’s as the two mares showed their hindsides, marehoods in full view and begging for domination.

Twilight’s arousal grew even more, clearly getting hard as she shivered in place.

'W-why are they doing that? Th-that's only making it worse!' Meadow protested, 'God you are so hard right now…'

Twilight ignored Meadow as she started to walk towards them, eyes locked onto their flanks as her mind was flood with lust.

Dawn looked up at Twilight, quietly saying, "Please go easy on my foals Master." She subtly shifted her body, separating her womb from the passage and leaving a little hollow at the end, so they would not be much more than mildly shaken.

'You adapt well.' the queen praised as Twilight approached.

Dawn wiggled her hip, looking down at the rod that Twilight was carrying and commented, "Is your mark a tower master? It's so big..."

Twilight stopped and blinked. "Huh?" She asked as the lust was replaced with confusion.

'Huh?' The queen mirrored her mate.

'... seriously?' Dawn asked, 'You've never had someone say that their penis is so big that their cutie mark must be a tower? Stalwart gets that all the damn time. Hell, I’ve even said it as much and Twilight laughed!'

'I have never heard that in my life.' Chrysalis insisted and went though he link. 'None of the drones have either, and I really don't see how those two things are remotely connected.’

'Way to kill the mood..' Dawn sighed and looked to Twilight to see if Twilight was still in the mood herself.

Twilight had softened a bit as she looked at Dawn confused.

Dawn curled up, saddened that they didn't know and she had only confused them, "Sorry master..."

Dawn shared her numerous experiences with Chrysalis, showing how she and others had used that phrase to compliment Stalwart or a suitably sizable stallion, her following suit after three others had.

'That still doesn't make any sense.' The queen said. 'Sure he's big but I don't see how that has to do with a tower or his Cutie Mark....'

Twilight became fully soft as her confusion was replaced with concern for Dawn.

Dawn sighed and then uncurled herself only to crawl beside Twilight and then under her, using her muzzle to rub against Twilight’s pleasurable zone, trying to bring some life into it as she replied playfully, 'Oh shush the analysis and help me tease him.'

The queen blinked and Twilight stepped back.

"Are you ok?" Twilight asked concerned.

Dawn paused, looking up at Twilight with a small frown of disappointment, "Should I not be?"

"You were just upset and curled into a ball a second ago."

Dawn sighed and gave up, pulling back and climbing up onto the bed. "Nevermind. I said the wrong thing and just… nevermind…"

She felt horrible. She felt like she had been doing her best to help tease like she was supposed to, yet the one cultural difference that she experienced often not being understood by either of them caused it to all fall apart.

Twilight's ears splayed back against her skull and her worry was replaced with being upset.

'Are you ok?' The queen asked concerned

'Not really, but I will be.' She replied quietly to her queen.

Twilight felt horrible not sure what she had done to mess up. "I’ll… I'll leave you alone… " she said and became Stonewall again before leaving the room.

Jeron: … I…. Legate… I can’t facehoof hard enough to express my frustration at what the hells happened without breaking my chitin! Here we were, ready to see a Stallion Twilight in action and it got halted so bad even the audience lost it! … I guess I should take a poll to see which author people agree with, that it was Twilight who couldn’t make a connection and roll with it or Dawn for making an obtuse sexual reference. Those who feel like saying it, I’ll be here… tasting your disappointment.
