Its been awhile since Celestia found out about her nephew didn't have his cutie mark anymore. But more importantly, the confession he gave to her about being a prince of Equestria, that he doesn't want the title anymore. Celestia blamed herself of not seeing the truth sooner about her nephew that he was forcing himself to be the way he currently is.
If she had found out the truth about her nephew sooner, he would of been a great noble for Equestria, but now with the way he is currently, she was thinking that she'll quit being a princess of Equestria and step down from power and let her sister Luna be the only one to rule Equestria instead of together as sisters.
"I..." Celestia started to speak but Blueblood raised a hoof to silence her. She looked at him.
"Aun... no... Celestia, after everything I confessed to you, maybe it's time for me to find a new calling somewhere else then here in Canterlot or even anywhere in Equestria. I know losing my cutie mark was a shocked to you, but..." He said but then sighed. "...maybe it's for the best that I don't get a new cutie mark."
Celestia was dumbfounded from this. "What... but why Blueblood?"
"I don't know okay?! Ever since my training to become a noble, I was getting less and less friendly and more of being a asshole to everypony I meet. Maybe I should change my name to Blueba-." He was interrupted by Celestia kissing him on the lips. His eyes widen from the sudden kiss from her.
Celestia then let go of the kiss she was doing to Blueblood. "Just shut up okay and listen alright?"
He just nodded.
Author's Note
The youtube video in this chapter is when Celestia gives Blueblood her memories of when she and Luna went up against Discord in the past, but ignore Twilight in the video because she wasn't there at all. You can replace Twilight with Blueblood as he'll be able to see what Twilight saw in the video.
Chapter 3(TBU)
It's been a couple of months since Celestia became pregnant with Blueblood's foals. Ever since that day when Blueblood impregnated Celestia, he became alot nicer for a noble and accepted as Celestia's special somepony. The news of that became a top headline in the newspapers all over Canterlot and even Equestria as a whole.
But something went wrong as Celestia felt Discord's seal in his stone prison started to break. She knew that she has to contact her student via dragon-mail for her and her friends to immediately come to Canterlot to deal with Discord after he broke free of his stone imprisonment to wreck havoc across Equestria like he did in the past.
But then she started to think that she can send her lover Blueblood to take care of the Draconequus himself. That stallion of hers have very potent sperm in his balls because just over a month ago, she asked Blueblood to get a sample of his cum and send it to the doctors here in Canterlot to see if his sperm potency would get anypony pregnant whether the pony was in heat or not regardless of gender. And she did got the results of that sample. As it turns out that Blueblood's sperm potency can, in fact, get anypony pregnant regardless of gender, which became a shock to Celestia as she didn't know that her stallion lover have this kind of sperm potency.
But now that she and her stallion lover Blueblood knows of this, she's willing to get Blueblood to have sex with Discord himself as she wants to know if Blueblood can, in fact, get Discord pregnant himself. She really doesn't care who Blueblood involves with himself for to have sex with. Even if it involves the dragon lord himself, she wouldn't mind at all as she's been thinking to start a harem with Blueblood with anyone who he has sex with.
Right now, she and Blueblood were in her day court as she sighed in worriedness. Blueblood heard that sigh from her as he turned his head to Celestia as he began to speak. "Tia, what's wrong?" He knows when Celestia does that kind of sigh and its not good.
Celestia closes her eyes. "Bluey, somethings wrong came up as I felt the seal in his stone imprisonment is breaking right now."
"Who?"
"I'll just send you memories of when me and my sister Luna went up against him okay?"
He just shrugs and then nodded.
She lit up her horn with magic as she lowered her head down to Blueblood, as her horn touches Blueblood's head, his eyes widen and glowed with light as memories flowed inside his mind.

When Blueblood blinked his eyes to get the glow away, he turned his head to see that fish were swimming in the air and then turned his head again as he heard hoofsteps going towards somewhere. Those hoofsteps belonged to both of his aunts, Celestia and Luna. But more importantly, they had scrape marks on their bodies.
But then he saw this being turned his chair that was on the tiled ground. This being had all sorts of different animal parts for his body. He then heard this being's laugh.
"This is so much fun, how about a game of pin the tail on the pony?" This being said as he got his Aunt Celestia's tail in his paw.
Celestia's wings extend outward as she lift her left hoof up and look behind her to see that she doesn't have her tail anymore and gasped. As for Luna, she looked to her sister and saw that her sister's tail was not there but didn't gasped as her sister did.
Blueblood continued to look at the scene in front of him and saw both of his aunts walked closer towards this being.
"Play time is over for you Discord." Celestia said.
So that's his name, Discord huh? Blueblood thought to himself.
Discord snaps his fingers and produces a small pouch. He munches on the strange looking snack it contains.
"Oh, I doubt that." Discord said. "Hungry?" Discord offers up his snack bag. They make no effort to accept his offer. "Suit yourselves."
Blueblood saw both of his aunt's horns lit up with magic as they brought out what looks like Elements of Harmony, but in gem form.
Discord then saw those gems and drops that snack bag of his and those strange seeds inside it onto the ground below him.
"Oooh. What do you got there?" Discord asked.
"The Elements of Harmony." Celestia said as the Elements of Harmony began to spin around both sisters.
"With them, we shall defeat you." Luna continued.
Discord just laughed in his chair. "You should see yourselves right now. The expressions on your faces. So intense. So sure of yourselves." He continued to laugh as Blueblood as his aunt's lit up horns touching each other as he saw a beam of rainbow coming from both sisters as it raised into the sky it got near Discord. "Hilarious." The beam of rainbow hit Discord as he continued to laugh and then Discord started to turned into stone as the Elements of Harmony did its job to him, imprisoning Discord into stone.
Blueblood then returned back to reality as his eyes no longer glowed brightly and looked at Celestia.
"Yes Bluey, what you just witnessed was when me and my sister Luna used the Elements of Harmony on Discord for the very first time back in the past. But now that he's breaking free of his stone prison..." She then sighed. Can't believe I'm saying this to him. "...I want you to have sex with him." Damn the fucking consequences of the future. Celestia will allow this change to happen.

Discord groaned as Blueblood was fucking his ass, but then he heard the unicorn sigh. His eyes widen from what Blueblood is doing. He heard the sound of 'pssss' as Blueblood was peeing inside his ass.
It's been awhile since the end of the Grand Galloping Gala, Twilight and her friends returned back to Ponyville after that night. Canterlot Castle been not that active since that night. The nobles of Canterlot were worried from one of their nobles, Prince Blueblood, even though he was called alot of names including Bratty Prince and Blueballs, they were worried that the prince wouldn't come out of his own room in the castle for anything, including the bathroom. Even Fancy Pants, Canterlot's most nicest noble, was worried about his fellow noble. Fancy Pants was the only noble to have feelings for the prince, even though he was married to Fleur de Lis. He was bisexual.
These concerns reached to Princess Celestia, the auntie of Prince Blueblood. She looked at the ponies current in her day court. "I know that everypony is worried about my nephew Prince Blueblood about what happened at the gala not that long ago, I'll go check on him and see what's wrong with him. The rest of day court is cancelled."
They understand and let the sun princess leave her day court to check on her nephew.
Princess Celestia left her day court room and went straight towards her nephew's room, as she drew in closer, she notice a disgusting smell coming from his room. This kind of smell reminds her of when ponies taking a shit in the toilet. There is no way that her nephew did this in his room, but she has to be sure.
So when she got to her nephew's room door, the smell was really strong and used her magic to block her nose. She then knock on his room door. "Nephew? It's your auntie. Ponies were worried and concerned about you not coming out of your room since after the gala was over."
It was awhile until she heard her nephew say or really yelled from inside his room. "FUCK OFF AUNTIE!"
Celestia's eyes widen as she never heard her nephew used this kind of language before. She has no idea on where her nephew heard that kind of word before. She just sighed and used her magic to get a battering ram from her pocket dimension.
"Blueblood! I'm respecting your privacy by knocking but asserting my authority as your auntie I'm coming in anyway!"
She used the battering ram and broke the door to pieces and saw what her nephew was doing.
