A/N: this is the end but I think y'all will like it. Enjoy and the picture I made it myself. Hope y'all like that too.

"Where are they?"
"Just hang in there Dumbbell Junior." Dumbbell told his son. "They'll be here any moment."
After five years together, Rainbow Dash and Dumbbell have been married and had twins of their own. Dumbbell Junior was their son and he was a lot like Rainbow Dash. Athletic, fast, and a demanding colt. Then there's their daughter Rainbow Sky. She's just more like her father but athletic just like her brother. But mostly sweet is what she is.
Dumbbell Junior had his father's coat color and blue eyes, but had his mother's mane and tail colors.
Rainbow Sky had her mother's coat color and magenta eyes, but had her father's mane and tail colors too.
Seems yet were identical twins with no cutie marks yet.
"I know work is real hard and it is my dream too," Dumbbell Junior said. "But I don't see why it takes so long for them to come home."
"Hey, with your mom being a Wonderbolt, it ain't easy. You gotta take is calm with her."
Seems after two years, Rainbow Dash finally passed her years at the Wonderbolts academy and became a Wonderbolt. She finally lived her dream, but she always remember her family first.
Suddenly, Dumbbell saw two Pegasus in the sky flying towards them and whispered to his son "Get ready. Here they come."
They flew, hiding behind the table as their mother and sister were coming home.
Rainbow Dash still had her Wonderbolts uniform on. She didn't feel in need to take it off.
"Next time Rainbow Sky, don't listen to your father about flying for me all alone please." She said to her daughter.
"Sorry mom." She said smiling. "Just been told this is a special occasion for you."
"What's the occasion?"
Then Rainbow Sky's smile got bigger and pointed her hoof towards their home. "This."
Rainbow Dash took a glance and saw loads of decoration all over their house. There was a table with a cake and some present on their including plates and silverware. There were loads of balloons and a banner that had big letters in magenta.
Dumbbell and their son pop out from the table an threw confetti in the air yelling "Surprise!"
Rainbow Dash was definitely surprise. Almost in shock. But then she smiled and flew down to the two stallions with her daughter.
"Happy birthday Rainbow Dash." Dumbbell said hugging his wife.
"Awww thanks guys." She said blushing pink.
"Mom, did you put on makeup?" Dumbbell Junior asked.
"Oh no. I guess I'm blushing a little. So who's idea was this?"
"Ours!" The twins said hugging each other.
"Yeah. Seems they wanted to give a very happy birthday, including myself, and we thought this was a good idea." Dumbbell said. "Do you like it?"
"Like it? I love it!" Then she hugged her husband with a big smile.
"Oh. Sorry we're late." They eats voices from behind appear.
Seems two long friends have finally join the party with presents in the mouths as they flew up to the home cloud.
"Hey guys." Rainbow smiled seeing her friends.
"Auntie Fluttershy and Twilight!" The twins were happy to see their aunts come.
"Hey guys. Heard your mother was having a party," Twilight said. "So we thought we stop by and join y'all."
"Now this party is perfect!" Rainbow Sky jumped up and down.
"Heck yeah!" Dumbbell Junior mostly hugged Fluttershy since she was his favorite aunt.
Rainbow Dash love seeing her foals be happy. By then, Dumbbell poked her shoulder and had a present in his mouth which was from him. "Happy birthday Rainbow." He said handing it to her.
Rainbow Dash began to open the present and was surprised by a familiar clip. It was the one she wore at the Grand Galloping Gala. She kinda lost it after a while.
She smiled. "Oh my gosh! I haven't seen this in forever!"
Dumbbell then grabbed it in his mouth and clipped it on her mane just like she did at the Gala. "Now you look just like my queen." He said.
"No no. Twilight's a princess." She joked making him chuckle.
Just then she gave him another hug a kiss on the cheek happy about this day.

Dumbbell seemed to be a good father and Fluttershy was definitely a good aunt. Rainbow Sky and Dumbbell Junior like their aunts since Twilight was a princess and Fluttershy is always willing to make them happy.
They played with the foals giving them a good day, while Twilight and Rainbow Dash remain in a loud eating cake. They enjoyed watching the foals play.
"I'm guessing the others couldn't huh?" Dash said.
"Yeah. Applejack and Applebloom are in Appleloosa, Rarity is on a big date, and Pinkie Pie also has to babysit the babies from mr and mrs. Cake." Twilight said. "But they all wish you a very happy birthday."
"And I think I enjoyed this one."
"I'm surprised they don't haven't there cutie marks yet."
"I'm sure Dumbbell Junior will get his soon since he's just like me. Rainbow Sky, I'm a little worried about."
"Oh I'm sure she'll be doing something great that includes her cutie mark."
"So, how is it being a princess and a wife to Flash Sentry?"
Seems Twilight Sparkle has finally married a guard from the crystal kingdom. She was certainly happy with him.
"Been nice actually. Flash is always on duty except for night, which I enjoy very much."
"Well that's good. Cause if he hurt I wipe his sorry butt."
Twilight only chuckled at her friend, still remaining herself.
"Hey Auntie Twilight!" They heard Rainbow Sky called. "Wanna play catch the boneless chicken?"
Twilight at Rainbow Dash wondering, and Rainbow nodded her head and she flew down joining the game.
Rainbow Dash was certainly proud of what her life has become. She has a family of twins, she's a Wonderbolt, and she still has the awesomest friends ever.
Just then, Dumbbell flew to her and sat on the cloud next to her surprising her. "Hey, why are you doing here by yourself?" He asked, worried if she's not happy.
"Oh nothing. I just like watching Twilight an Fluttershy with the kids."
He smiled, knowing that wasn't it. "Come on Rainbow Dash. I've seen you lie better than this."
Seemed he caught her since she said "Okay. I guess I'm a little worried about Rainbow Sky. I mean, why if she never gets her cutie mark and she doesn't have a future. We can already tell Junior might have one, but Sky I'm really worried."
"Rainbow Dash, it takes time getting a cutie mark. You can't just force it. I think whatever happens with Rainbow Sky, she'll have a bright future."
Rainbow looked back down at her disgusted and still worried. But maybe he was right. Maybe she will have a brith future and her cutie mark very soon.
She smiled look up at him and said "I guess you're right."
"Well that's good. I mean, you already have a future. An awesome mom is what you are as a Wonderbolt."
"Well I believe that's good." But then she pushed him against the cloud being on top and smiled "Cause if you don't show up at my next performance, I'll kick your tail."
He smirked at his wife. "I'd like to see that, Rainbow Crash." He teased with her old nickname.
She smirked and kissed him on the lips enjoying the feeling she's always had in her stomach.
But their moment was ruined with Junior's interruption. "Ew! Mom as dad are kissing!"
They laughed of how silly their son was being.
"Now Junior, that wasn't very nice." Fluttershy said.
"No it's okay Flutters." Dash said. "He'll learn."
"Nope. I'll be heartless." He crossed his arms.
But then his sister flew towards him and said "You already are heartless."
"Am not."
"Are too."
"Am not."
"Okay guys." Twilight stopped the fight. "Hey who wants more cake?"
"Me!" They cheered flying back down with the aunts.
They finally left them alone and Rainbow Dash continued to kiss the love of her life.
And it seems their children did have a better future.
Dumbbell Junior was able to be in a flight school and his cutie mark was a thundering cloud of fast and furious. He was very athletic in his schools.
As for Rainbow Sky, aunt Rarity fell in love with her niece. Not literally. Seems Rainbow Sky loved the idea of fashion ask wanted to create her own work. She made a rainbow scarf as a silly and earn her cutie mark. It was a needle in thread making the scarf. She began helping Rarity with any ideas if she ever needed her.
Rainbow Dash and Dumbbell stayed together no matter what. And as much as most couple say, they were the happiest couple in Equestria.
And they all lived happily ever after.
