Rainbow & Blueblood's Best Night Ever

***

***

After both Rainbow & Blueblood sang these songs, they looked away from each other, but they looked back with love in their eyes. They both got close to each other and then they closed the gap, kissing each other. They both closed their eyes as they deepen the kiss. Rarity saw this with her eyes widen, her shining armor, kissing Rainbow... maybe it's for the best. Rarity sighed sadly as she left the ball room, probably to go to Applejack's stand to get something or whatever. Rainbow & Blueblood continue to kiss each other as they wrestle their tongues together. After a moment of this, they let go of the kiss, leaving a string of saliva from their mouths. They look into each other eyes as they smiled lovin'ly.

After sometime, Blueblood was the first to say something. "We can continue this in my room, here in the castle. Auntie Celestia won't mind in the slightest if her nephew is in love with a commoner. I may act like a snobby noble to Canterlot, but sometimes..." He looked around and whispered to Rainbow. "I really act like a colt that wants to have adventures." He sighed as he looked down. "I really miss those days to have fun and not worry about all of the nobles that the only thing they think about is money." He looked back up with a small sad smile. "You know? Let's just get to my room."

Wow... I never knew this side of him before. Maybe I can do something for him so we both can have fun. Rainbow thought to herself as she and Blueblood walk towards his room.

They both were chatting as they were walking towards his room. They talked about each other, like their names and stuff. Including this piece of information. They were only halfway towards his room when this topic came up.

"Soo... you had any love in your life Bluey?" Rainbow asked him about if he had any love in his life to this point. And yes, she started calling him Bluey when they were talking. He liked the nickname she gave him, reminded him of his young life as a colt.

Blueblood thinks about this for a few seconds. "Well... yes, but not love-love like you & me."

Rainbow slide her head to the side. "How so?" She was confused and curious about this.

They both stop as Blueblood puts his hoof under his chin and ponders about this. "Well... its just... it's for the royal bloodline type of marriage. To marry somepony they didn't know about at all and they all of a sudden, got married for to continue their bloodline that they didn't want at all. I didn't want to be married with several mares that I didn't like at all, but Auntie Celestia said it's for my own good. And now I'm stuck with 3 mares that want me for my money and sex only and not what I want."

Rainbow just let all of what Blueblood said to sink in. After a couple of seconds. "Wow. That's not right at all. I think I can help you with your problem Bluey...... Say, whose are those mares did you get forcefully married into anyway?"

"Well... their names are Jane Lilly, Katie Fang Lee, & Maddie Coltterson." Blueblood said as he tells Rainbow who he was forcefully married into.

Rainbow ponders about this for a few seconds before saying. "Can you do anything to get them to unmarried to you, like at all?"

Blueblood shakes his head. "Sorry Rainbow, I can't do anything about that. My auntie made it public about my marriage to those 3 mares when she was there for it."

Rainbow just groaned in frustration. "That fucking sucks Bluey. Let's just get to your room already."

Blueblood just patted Rainbow on the back with a hoof. "I know. And yeah. We're only halfway towards my room right now."

They continued walking from there and they chat some more until they get to a blue door that saids "Blueblood" on it.

"Well, here we are, my room. Those 3 mares should be still in that ball room. Now I gotta unlock it first." Blueblood said before using his magic to get the key to his room out of his pocket dimension to unlock the door. The key in question is a special shape kind of key. Like those special made keys that are for dungeon rooms. He got it out and used his magic to float the key to the keyhole, he turned it until it made an unlocking sound. He then put his key back into his pocket dimension. He then turn the doorknob, opening the door. "Well, mares first." He said suggesting a hoof over to let Rainbow in.

"Thank you Bluey." Rainbow said thanking him.

"Your welcome. Now let's get inside before those 3 mares decided that I'm not in the ball room at all and come here." Blueblood said letting Rainbow in his room.

Inside Blueblood's room looks like what you see in a noble's room, well a noble that is a nephew to Princess Celestia Solaris. There are a couple of paintings that look like ponies from olden times, a prince-size bed(aka king-size) with royal blue coverings on it, the decor is what Blueblood suggested to his auntie when he didn't have a room to begin with when he became a prince, the flooring is a special carpet type, couple of plotted plants, some books from the Royal Canterlot Library, and a chest with all kinds of stuff ranging from sex toys that those 3 mares forcefully used on him to foal toys.

When Rainbow looked around his room, she notice the chest with the weird smell. She pointed a hoof over to the chest. "What's that Bluey?"

Blueblood just locked his door when he notice where Rainbow is pointing her hoof at. "Oh that chest. Well..." He also notices the weird smell coming from that chest. "I will say that those 3 mares... don't do gentle at all and instead do forceful on me with those sex toys that they brought over from the local Canterlot Sex shop called Le XXX Sex Shop. It was very painful that they used those toys on me. They raped me Rainbow. They never let me cum... at all. They started to call me Blueballs because of me getting blueballs. I still do have blueballs, look."

Rainbow took a look behind Blueblood and saw that his balls were indeed blue and were kinda big. "I can see that Bluey, also your balls are big as well."

"What? Let me look." Blueblood said before moving his head so that he can look under him. There, he saw that his balls are indeed big as well. "I can't believe that those 3 mares caused me to have this, so can you help me release all of that cum?"

Rainbow smiled. "Sure. Want me to do oral or go straight to my marehood? Or here's a 3rd option... cock docking?"

Blueblood raised an eyebrow at that 3rd option. "What's cock docking?"

"Well, it's when you put your cock inside the other male's cock." Rainbow explained.

Blueblood still has his eyebrow raised, but has disbelief on his face. "How? You're a mare. And I don't see an-" Blueblood stopped to see that Rainbow is on her back on the floor with her legs being spread apart showing him that she has a sheathe and balls. Blueblood blushed. "I stand corrected. I guess you do have a cock." He then twist his head so that he can have a look down there. He sees Rainbow's pussy and ponut as well. "What kind of mare are you?"

"I'm a futanari mare. I have both genitals. Soo... yeah cock docking... want to do that?" Rainbow said as she just started to float off the floor and flew to the bed before laying on her back on it.

Blueblood sees the cock twitching, thinking on what his marefriend Rainbow asked him. He haven't done this since he was a colt. He was curious at the time, but now with being a prince and being married with 3 mares he didn't loved at all, I guess I'll try this. He just nods at what Rainbow suggested.

"Cool." Rainbow said. "Now just line your cock above mine and we can get started." She really loves him with all of her heart and wanted to do this with him. "But before we do that, I might have an idea on what we're gonna do tomorrow."

His ears perked up at that statement from his marefriend as he let out a 'hm?'.

Rainbow is about to tell her stallionfriend, the, most, evilest, pla-I mean idea ever. "Well..." She rubs her hoof behind her head. "If you got a fetish for killing, tomorrow, we kill those 3 mares while their drunk with a special drink that I got in my saddlebags and act a list of fetishes that I'll be writting down before you wake up tomorrow morning. Soo... how about that Bluey?"

While Rainbow was saying that, Blueblood's eyes widen, his jaw dropped, but the idea of killing those 3 mares made his cock even harder than ever as it was leaking pre. He has his own ideas on what to do tomorrow as well with those 3 mares. When Rainbow was finishing speaking, he got a question to ask her. "Well before I answer that, I got a question of my own to ask you."

Rainbow's look telling him to 'go on'.

"Do you want to marry me now, so I can tell Auntie Celestia about this tomorrow?" When he asked that question, he saw her eyes widen at the sudden proposal of marriage.

Rainbow nodded her head, telling him yes. "Yes I do now." As she said that, she leaped on him and kissed him on the lips. Making lip contact with him. He closed his eyes and kissed her back. His cock twitched as he felt a hoof on it, rubbing it. More pre was coming out of his cock. He moans as they continue to kiss.

After a few more seconds, they both let go of the kiss. Rainbow's eyes were like of a predator, hungry for more. Blueblood's spine tingle as he saw those prodigious eyes of hers. The cock rubbing stopped as he continues to look into her eyes. After a few more seconds, he finally understands what she wants to do next. He leans towards her ear and whispers 'want the cock docking now?'

He leans towards her, making her lay on her back on the bed, his cock still very rock hard, lines it up to hers that was standing up straight, erected than ever, twitching with each of her heartbeat.

He then went down onto her, his cock into hers, the sudden penetration of both cocks inside each other made them moan loudly. They looked at each other, their expressions on their faces telling each other that this felt right. Both of their cocks are fully inside of each other. Pre going through each of their cocks, making them twitch. His cock was sensitive from denying of his orgasm from reaching his peak from those three mares before the Gala even started.

Then they both started to deeply kiss each other, their tongues touching each other. They moan in their mouths as he started to begin fucking this mare in the dick. They continue to fuck each other for awhile until he felt his loins begin to stir. He was about to have the biggest orgasm of his entire life after being denied of his orgasm. He was about to cum inside Dash's cock. She was close as well.

They both fucked the fastest they can go until both of their balls clenched as they both started to cum inside of each other. He let out a sigh of relief as his balls were finally be abled to pump out cum of them. He even felt his balls were growing and shrinking as both of them exchanged cum from both of their balls. After a couple of moments, they stopped cumming. They were spent and trying to catch their breaths from the aftermath of their orgasms.

None of them wanted to say anything at the moment. They smile at each other.

Rainbow felt pain in her bladder. She drank alot of the stuff the gala was serving and now she has to pee, badly. She chuckled. "Uhh Bluey..." She started to say. Both of their cocks were still inside each other, not softening at all. "...I have to pee, like right now."

If there was one thing Blueblood did when he was alone in his room without anypony bothering him, it's drinking his own pee. He has a huge watersports fetish and hearing Rainbow saying she has to pee right now was making his cock twitch in her cock. On a few occasions even though he's a prince by title, he likes being a urinal for any male species. And now he gets to be a urinal for Rainbow as she was about to pee into his cock.

She even felt his cock twitch in her's. She takes a deep breath and lets out a sigh, relaxing her bladder muscles. Her bladder relaxed as urine exited her bladder. She felt the urine going through her cock and into Bluey's cock.

He felt her urine entering his cock and going inside his balls. He felt his balls were growing from urine entering there. He never had somepony pee inside his cock before. He let out a moan as his balls continue to grow. If you had x-ray vision to see inside Blueblood's balls, then you would have seen that, both cum and urine in there began to merge, creating something entirely new in there.

Rainbow kept on peeing for to seem like forever, but in reality, it was only for about 2 more minutes until her bladder felt empty. That was when the last of her urine came out of her cock.

She let out a sigh of relief as she was satisfied. Her cock finally begins to soften after peeing for 2 1/2 minutes. It was siding out of Blueblood's cock as it was retreating back into her sheathe. After a little bit, her cock was fully back inside her sheathe.

But as for Blueblood's cock, it was still erect and hard. His cock continues to twitch from his heartbeat.

She can tell that he's not fully satisfied. He needed relief from his huge balls. She put a hoof under his balls and touch it. That made Blueblood gasp from the touch. She felt that it was full of both cum and urine in there that needs to come out.

She looked at him. "You know after I peed inside your cock and after felt your huge balls with my hoof, I think I know how to get your erection to soften."

He raised an eyebrow. "And that is?" He was curious as to what his current marefriend Rainbow will do.

"I need you to fuck me hard, in my marehood." She said with a needy look on her face.

He couldn't believed what he was hearing. Rainbow Dash, the element of loyalty, and current marefriend to him, needed him to fuck her in her marehood, hard.

So, she got up from where she was and raised her rump in the air, facing towards him, and then came down on his cock in her pussy. She went down on him that the base of his cock was touching her. This continues for about a minute. She could really feel his cock twitching inside her pussy.

He let out a groan as he felt his balls clenched up and released his load inside her womb. Painting her insides a yellowish-white as he came.

Rainbow felt her womb was filling up with his sizable load, spurt after spurt. This continued for about 30 seconds until his cock stopped cumming inside of her.

He let out a sigh as his cock finally begins to soften and back into his sheathe. After his cock was out of her pussy, the leftover of his load begins to fall onto his softening cock and balls.

His balls are finally back to its normal size after cumming like that.

"I'll definably become pregnant from all of your cum that's still inside of my womb. Thank you Bluey." Rainbow said while smiling.

"You're welcome." He said. "Now you can get off of me."

She did.

Both of them were getting tired from all of this sex. Rainbow was still in his bed, but lying down. While Blueblood was still lying down, but moving over next to Rainbow.

They faced each other. They kissed one more time before falling asleep.

"Night Rainbow."

"Night Bluey."

And now they fell asleep, together dreaming of their plans for those 3 mares tomorrow.
