The boys finally arrived at the castle and were excited about their first actual date with Lyra and Bon Bon. As soon as they got to the castle gates. They decided to wait for the girls. Besides it would be extremely rude if they went in and not be patient for their girlfriends.

"Alright George. This is it. The big night has come." Harold smiled.

"It sure has. And since Celestia made us the guests of honor we really should thank her for this." George said.

The two nodded in agreement and knew that they will thank her for everything. Then right on cue the boys see a carriage coming into view. It landed right in front of them and we see the girls coming out in there beautiful dresses. Even Lyra and Bon Bon were in lovely dresses too. Lyra wore a sky blue dress and Bon Bon had on a hot pink dress.

"Yoohoo! Boys! Your dates have arrived!" Lyra called out.

George and Harold saw them and went to them giving them each a kiss. They also blushed by their beauty. They couldn't deny that they are beautiful.

"Whoa. Bon Bon. You look beautiful tonight." Harold complimented.

"Thank you sweetie. And you look quite handsome yourself." Bon Bon said.

"So you boys ready to have the best night ever?" Lyra asked.

"Oh yes Lyra. We sure are. And Lyra? Since Harold and Bon Bon want a private waltz would it be okay if me and you had one too with them?" George answered.

"That would be lovely George! You couldn't possibly be more romantic than you are now if you tried. Yes I would love a waltz with you. Now take our arms and lead us in. Will you?" Lyra asked.

"Sure thing my lady." George answered.

Lyra blushed and George gently took her hoof and led her in the castle. Harold did the same thing with Bon Bon. The Mane Six smiled seeing the boys treat them with lots of respect and showing good manners. In the castle the gang were walking down the halls and the boys saw a colored window of them and Captain Underpants defeating Chrysalis in her monster form. Then they all reached the doors to the ballroom and opened them. Celestia and all the other ponies smiled seeing them here tonight.

"Twilight Sparkle. I'm so glad you made it here." Celestia smiled.

"Me too princess." Twilight said.

"And it's an honor to have you boys here. I hope you liked that little present in the hall I left for you." Celestia complimented.

"That colored window of us and Captain Underpants defeating Chrysalis? Yeah we noticed. Thanks for that." Harold smiled.

"Your welcome. Now go enjoy the Gala everyone." Celestia said.

Soon everyone separated to do their own thing but George and Harold wanted to stay with Lyra and Bon Bon. The girls didn't mind it and they loved their boyfriends company. Then the two couples heard some salsa music and decided to break out a move. The musicians started playing and the gang started to move.

We see them dancing and doing the tango while everyone was watching our stars going at it. George and Harold pulled off some spicy moves and Harold held Bon Bon by the waist and lifted her in the air doing The Flying Eagle. After that he placed her down and continued dancing. George and Lyra were doing the tango and twirling around. But then George had an idea to do a special move known as The Flying Peacock. He lifted her in the air and twirled her around like she is flying like a bird. Then he put her down and continued dancing. Then the two boys salsa danced for the girls as they grabbed some fans covering their faces making them look sexy. Then they all danced til they did the tango again. They continued dancing til when they got to the end they posed ending the dance. Everyone cheered seeing a wonderful performance as they took a bow and sat back at their table.

"Wow George you were amazing. Now I can honestly say that my feelings for you are stronger than ever and our relationship is unbreakable." Lyra smiled.

"Thanks but I'm not taking all the credit. You were great too." George reminded her.

"Thanks babe. And I see Harold and Bon Bon having another moment." Lyra said pointing at them.

We zoom out seeing them staring lovingly into each other's eyes and had yet another kiss. George chuckled at that and Lyra wrapped her arms around him.

"They really love each other don't they?" Lyra asked.

"They sure do. It's like the love lava keeps boiling and with never cool off." George replied.

Meanwhile with Harold and Bon Bon they separated lips and held each other close.

"You just couldn't stop loving on me could you sweetie?" Bon Bon smirked.

"You're too beautiful and cute so I couldn't stop if I wanted to." Harold replied.

"Oh you." Bon Bon giggled. "Hey you still giving me that private waltz right?"

"Of course Bonnie. I never forgot that." Harold answered.

"Bonnie? I love that nickname. Lyra used to call me that sometimes." Bon Bon smiled.

Harold took her hoof and led her to the place for their private waltz. At the same time George and Lyra followed them to the place too. They all arrived in a special garden and everywhere they looked there was beautiful flowers blooming. They noticed that George and Lyra wanted to join them in this and they accepted Then Bon Bon saw Harold playing a special tune that would truly make this night the best.

"Aww sweetie you shouldn't have." Bon Bon smiled.

"But I should. Since you asked us to be your dates I have to make this special. Come now. Let's waltz my princess." Harold said.

"As you wish my handsome prince." Bon Bon replied.

They both held hands and started waltzing. The same thing was happening with Lyra and George. Then like a fairytale ending both of the couples were doing their private waltz in the garden before Bon Bon lays her head on Harold's neck, and Lyra laid her head on George's neck. But what they didn't know is that watching behind was The Mane Six who couldn't stop seeing them so happy together.

"Were happy for you boys. You have your princesses." Fluttershy smiled.

The girls left leaving the couples to continue their waltz. After that we cut to the night seeing the treehouse the boys lived in. The two changed into their cozy pajamas, hung up a picture of them and their girls on the wall, grabbed a cookie and A glass of grape soda and looked at the night sky.

"What a great night it's been. And we earned ourselves a girl." George smiled.

"Yeah. You know I never thought I say this but I really think me and Bon Bon are two peas in a pod." Harold replied.

"You kissed her like 20 times. It's quite clear that you are really in love with Bon Bon." George laughed.

"Yeah you could say that. Well I'm really tired George. Let's rest up for the night. We got a big day with Lyra and Bon Bon tomorrow." Harold said.

"We sure do. Okay Harold. Night bud." George said.

"Night man." Harold said back.

George went to the lamp and turned off the light. Then the two crawled into their beds and soon enough they fell fast asleep smiling and dreaming about what tomorrow brings them in Equestria.
