After Spike finished having his way with Princess Celestia, he took his dick out of her anus and it was leaking huge amounts of cum out of her ass as she fell on the table. Cadance and Luna both went over to the table where Celestia was laying and grabbed the leaking jizz. After looking at it for a brief second, they put it in their mouths and swallowed it, shocking Spike.

"You sure know how to please a lady, Spike~. Shining Armor would be jealous of you~." Cadance said.

"I agree, Cadance~. There doesn't seem to be a colt in Equestria who can measure up to my nephew~. You are very lucky, sister~." Luna said, patting Celestia on her bouncing ass.

Spike was more exhausted and confused than he ever was when they complimented him on his sexual prowess. On one hand, he felt happy that he was being commended for being useful in pleasing his mother, but on the other, he felt a little weirded out that he had to show it to his relatives. But then Luna said,

"But before we can carry this any further, we need to get ready for the gala and we need the proper attire for the occasion."

"You're right! We have to look proper for the guests and we don't know what to wear. Spike?" Cadance said, looking at Spike.

"Yes?" Spike answered.

"Would it be any trouble if you would... go shopping with us?" Cadance asked.

"Oh no! Just... let me get dressed first." Spike said, looking at his dirtied clothes.

"We'll join you then~." Cadance said, taking a hold of Spike's arm.

"Yes, we shall~." Luna said, holding Spike's hand.

On that note, Spike and the two princesses exited the kitchen, leaving an ahegaoed Celestia resting on the table.

Three hours later, Spike and the princesses were out and about looking for dresses to wear at the gala. Walking through shop after shop, they were coming up short on what dresses they should wear.

"There are so many shops here." Cadance said.

"Indeed. No matter where we go, they are all the same." Luna lamented.

Then Spike interjected,

"Wanna try one Rarity's boutique in Canterlot?"

"Hmm. I suppose it wouldn't be a bad idea. And knowing your friend, she more than likely has the perfect choices for what we wanna wear." Cadance said.

"Agreed. We will have more than enough choices for what to wear at the gala." Luna said.

"Well, let's go!" Spike said in full enthusiasm.

With that said, they made their way to Rarity's Canterlot Boutique where they were greeted by Sassy Saddles.

"Sew my stitches! What a pleasure it is to see you, princesses! You too, Spike!" Sassy Saddles exclaimed.

"Hello, Sassy Saddles. Do you happen to have any dresses that are fit for the gala?" Luna asked.

"Hmm. I do, but I would have to take some measurements if you want to be ready. But first, is there anything you three would care to try out?"

"Hmm..." Luna wondered.

Luna and Cadance proceeded to pick out the dresses that seemed to impress them. After five minutes of choosing, they took the dresses and went into the measuring room while Spike stood outside and read some random magazine hanging by the register.

"Hmm..." Sassy Saddles wondered as she measured Luna.

Luna kept her arms held up as she waited for Sassy to finish measuring.

"You seem to be a size 130 around the bust. As for the waist, you measure around 72. Your hips are also around 98. You're also exceptional tall around 6'7, although not at tall as your sister. You've been doing good in keeping active, Your Highness." Sassy explained.

"Thank you, Sassy Saddles. What dresses would you recommend?" Luna asked.

"I would recommend a dress that would come with a bustier concerning the size of your bosom. I could make a custom dress for you, but it would take awhile and the gala would have already commenced before I even begun. Would you be okay if I picked out a dress that would make you feel comfortable yet not leave you too exposed?" Sassy consulted.

"I would be more than happy." Luna said.

"Your turn, Princess Cadance." Sassy said, turning towards Cadance.

After measuring Cadance's bust, height, and waist, Sassy said,

"Your bust is around 101. You're height is around 6'2. Plus, you waist is around 57. I think I may have a few dresses, but you would have to choose because we're low on stock and materials for making dresses at this time. Is that okay with you?"

"It would be my pleasure, Sassy Saddles." Cadance said.

"But Sassy Saddles, would it trouble you if Spike would help us choose what to wear in here?" Luna asked.

"I don't see why not. I just don't want any misbehavior occurring in my shop if you catch my meaning. But if that's what you want... Spike!" Sassy Saddles shouted.

"Yes?" Spike answered.

"Would you come into the dressing room, please? The princesses want your opinion!"

Hearing this stumped Spike upon being asked that question. The last thing he wanted to do was to awkwardly stare at the princesses as they try on different dresses, but he was in no position to argue as he was asked to come in by the princesses. Knowing that he had no other choice, he got off his seat and went into the dressing room, but not before taking the magazine with him. Before he could go in however, he was greeted by a voice that he knew too well to deny.

"Hello, Spiky~." the voice said.

Knowing full well who it was, he reluctantly turned around and saw that it was Princess Celestia who has recovered from her anal penetration."

"Hi, mom..." Spike said in a glum manner.

"Oh, don't be like that~. You were only trying to prove your dominance~. Are the ladies trying on new dresses~? Let's go in~!" Celestia suggested.

"Uh..."

Before Spike could object however, Celestia grabbed him and went inside the dressing room, where Cadance and Luna were waiting for Spike, but not expecting Celestia.
