FrostBite and Nightloo landed on the balcony of his house moments before Pinkie poked her head out. "Oh good. I found you." She chimed. "There's a surprise for you two in the play room."

"The play room?" Nightloo asked.

"The sex dungeon, silly." Pinkie giggled. "Oh and Dashy went to get some things for the party."

FrostBite and Nightloo look at each other in confusion for a moment before letting out a sigh and starting to make their way down.

As they passed the living room, they greeted the other members of the herd and introduced Nightloo's new look. While most of their herd mates were happy for her. To nopony's surprise, Twilight wanted to do several tests to see what all changed and any possible dangers they may need to look out for.

Thankfully however, Pinkie was able to distract her long enough for the two to slip down stairs.

As they get downstairs, the two glance at each other, neither of them fully knowing what to expect. To their surprise, as they opened the door Chrysalis was sitting with the princesses with a tendril of magic connected to them.

"What are you doing here?" FrostBite asked.

"Luna asked me to scan her sister and the dragon lord to see if there's any lingering magic. Or if they have been… mounted before coming here." Chrysalis replied with a smile. "Oh. And I was going to ask about hopefully starting a new Hive in town."

"Did you talk to Twilight about it?"

She sighed and nodded. "If you say it's ok. Then Twilight will have a plot of land set up for it."

FrostBite narrowed his eyes on her. "And?"

"And I promise to run everything by you before attempting and plans."She sighed… speaking of which. I would like to seek out a mare to make the next queen."

Hearing this Sweetie Belle spoke up. "How would that work? Would the princess need to feed on love? Wouldn't she need to join the herd?"

Chrysalis smiled at her then glanced at FrostBite. Shrugging he smiled. "If she wants. Then go for it. But she does bring up good points."

Chrysalis nodded. "There are ways to make a pony part changeling. But it takes a lot out of a queen to do each time. So I won't do it often unless I have the strength. And that would require a lot of love energy." She explained, cutting the connection to the others. "It would be easier if they were a part of the herd. More love passes between all of you than I've seen since the wedding. And being part changeling means that a part of you diet will include love. But you can get that easy in the herd. Even if you just stay in the same room as them." She turned to each of them and asked. "Does that answer your questions?"

"Will it hurt?" Sweetie asked.

"You'll be asleep. So no." She tapped on the cage thoughtfully. "It's not an ideal. But I may be able to use this in place of a traditional cocoon." Seeing Sweetie smile excitedly, she smiled and started and started vomiting out a green goo as her hooves worked to wrap the cage as Sweetie noticed a violet liquid start to fill the cage the more goo covered the cage.

Shrugging the two turned to the princesses as Luna came over with a soft smile. "Hello alpha. Have you come to claim your prizes?" She asked softly before noticing Nightloo. Blinking, she gasped and let out an excited squeal. "I can't believe what I'm seeing. Scootaloo?"

Nightloo smiled and bowed. "Please. Call me Nightloo."

Luna smiled and nodded. "Nightloo. I am pleased to see you taking this path." She let out a soft sigh. "I only wish there were more of the old guard left. So few bat ponies live. And even fewer that are well enough to hold the mantle."

Nightloo thought for a moment and smiled. "Well… maybe we can fix that. And… you can teach me about the old guard?"

Luna smiled and nodded. "Then let us go to another room so that your mate and my sister may have some time alone."

With a nod the two left the room soon followed by Chrysalis and the cocooned cage, leaving FrostBite to look at the two nobles. Biting his lip FrostBite bullet off their blindfolds and removed the gags.

"I didn't expect to meet you like this. But… hello princess… I'm FrostBite."

"Celestia." She panted. "Would you be so kind as to release us?"

Smiling nervously he rubbed the back of his neck. "I would. But there are a few things we need to go over before I do that."

"Such as?" Ember asked.

"How big is your herd, Ember?"

She blinked and looked away. "I… lost it to Spike…" Sighing she smirked at him. "So you won our game. As expected. Claim your prize when ready."

He nodded and turned to Celestia. "Don't worry. I don't plan to try and take over Equestria. If that's what you're worried about."

Celestia smiled for a moment before moaning at the feeling in her hindquarters. "Then am I right to assume that even if we join the herd, you won't be against us continuing as the rulers."

FrostBite smiled and nodded. "Though if you two do end up getting pregnant. I have a feeling the ponies would ask questions."

"You have a good point." Celestia sighed. "But don't worry. It wouldn't be hard for them to believe that I asked a stallion to father my offspring." She sighed. "Though I would likely prefer them to know who the father is. If you are not against that."

FrostBite smiled. "If it means that I can be a part of their life. Then I would love that." He made his way behind her with a soft smile. "And I'm glad to see that your sister is so excited about Scootaloo becoming part bat pony."

Celestia blinked. "Oh? Has anypony else gone through any other changes?"

"You didn't hear about Sweetie Belle?" He asked.

"My sisters put an enchantment on the blindfold so I wouldn't be able to hear." She explained.

"Bloom is part timberwolf, Rainbow is part dragon and Sweetie is going to be part changeling and Chrysalis's aer." He explained.

Celestia listened closely to his explanation before giving him a look of shock. "Chrysalis?" He nodded. "You truly are an alpha among stallions to have such a queen bow to you. Once we are done here. I would like to see the girls for myself. If that is OK with you."

Mounting her from the back, FrostBite smiled and lined his dick with her pussy. "I think I can arrange that. But for now. What do you say, I welcome you into the herd. Properly."
