Demon Dragon

Spike and Luna was having the time of their life. Luna felt like she had reached paradise, wich wasn't a surprise considering she hadn't had sex in over a thousand year's, because no pony could fulfill her need's. Luna was laying on her back on Spike's bed.

She was wearing a blue dress that blended in to her skin, she was so close to just ripping it of from her body, and go into full go sex. Spike was kissing her lovingly and passionately, making Luna moan.

Spike started removing the dress from Luna, but he didn't want to rip it. He still wanted her to wear something when she left. Luna guided him in helping her take of the dress. Eventually she was just wearing her bra and panties, that looked like it could flood a whole pool. Spike grinned at this and started taking of his t-shirt pant's sock's and eventually his underwear.

Luna looked at Spike's cock in absolute bliss and shock. His cock was atleast twenty centimeters! She was going to have fun....

Luna quickly cast an silencing charm in the room, and Spike put his cock into her soaked wet marehood. Luna gasped in glee and bit her lip's. Spike got into a nice rhythm. He got in and out slowly as to not hurt her. She haven't exactly had sex in a thousand year's, wich probably have made Luna almost crave some stallion's cock.

Spike continued slowly and eventually went a little bit faster. Luna was moaning so loudly, Spike thought that Lucifer was looking up in wonder. Spike couldn't blame her tho, she hasn't had "good sleep" in a while.

"Oh....oh my.........God.........Spike.........I'M GONNA CUUUUUUM!!!!" Luna shouted at the top of her lung's. She cummed all over Spike's cock and went also over the bed.

Luna looked like she was sent to heaven, wich Spike can't blame her for. Demon's also have feel's like that. Because they have sex incredibly often, their lust is very strong. Asmodeus is never late to give any demon their pleasure.

Spike continued as he hadn't cummed yet, and started building up the rhythm. Luna let out a cute 'EEP' and soon she started to enjoy herself more. Spike eventually had to release wich took a while, then again he is a half dragon half demon.

"Luna I'm gonna-" Spike started, but was cut of by Luna.

"Do it Spike. Do it inside me!~" Luna said, in a seductive tone.

Spike shot his cum inside Luna, who gasped in shock and soon started to grin like she had just won.

'I maybe sharing Spike with Nightmare Moon and Chrysalis, but out of all the ponies in this castle, he is all mine~" Luna thought seductively.

Spike pulled out of Luna who sighed in bliss. She all of a sudden got sex ideas with her other two partner's. She liked Chrysalis's body. She would do anything for that body! She wasn't even surprised that her nephew love's her, heck she is starting to....

She bolted almost out of bed, making Spike look at her with boredom on his face. She looked at Spike, and she knew he would be mad at her. She had to tell him tho, she just had to.

"Spike, i-i think I might be developing f-feeling's for the other two." Luna said, she was now expecting him to shout at her in anger, but it never came, instead he was laughing as if it was the funniest thing he had ever heard.

"Luna, I told you," Spike started but started laughing a bit. After a few seconds he continues. "I was in an open relationship, I fact I want you to develop these feeling's."

Luna felt her face become red from embarrassment. She had forgotten about that. She went over and hugged Spike. Spike hugged back. They were like that for a few minute's before they thought it would be good to go down.

Luna put on her dress and made sure her hair looked presentable. She looked stunning again. Spike put on his business outfit and looked like he was in the mafia or something.

Luna looked at him surprised, but shrugged it of. He is Celestia's son after all, he is bound to get some money.

Luna walked down first, and Spike came down a few second's later, heading for the kitchen.

"So what did he need you for?" Celestia asked, her sister deeply curious.

"Well, I helped him relieve his stress." Luna said, smirking at the faces she got.

The main five and Starlight looked completely shocked. Would Spike really go that far? Then again he has been distant from them since the day they got to know him. Celestia and Twilight looked like they had been hit with a baseball bat.

"Why sister? Why did you do that?" Celestia asked, shocked.

Luna gave her sister an expression that said: "make up you're mind" and Celestia looked away.

"Sister, you have been talking non-stop about his estrus, then he start's to make-out with me and we have some fun." Luna said, as if it was no big deal.

"WAIT! SPIKE MADE OUT WITH YOU!?!" Twilight screamed in shock.

"Yes, I did Twilight now please stay out of family affairs." Spike said, with a hint of bite.

Everypony in the room looked at Spike gobsmacked. Spike only talked like that when he was irritated or angry, and even Discord is very wary of when Spike is angry.

Twilight looked a little hurt, but didn't say anything.

"Spike, I'm sorry, but you can't leave the castle during you're estrus cycle." Celestia said.

"Why? I don't see you saying anything when it happen's to mare's." Spike said, in a tone that made everypony except Luna flinch.

They also flinched because he had a very, very good point. Celestia thought about it and sighed. She knew this was gonna come up, and she didn't really have a backup plan since she can't deny what he is saying.

"Besides, what right do you have over me? I'm eighteen, and I haven't exactly had a mother when I grew up, so for the love of the Shadow Pony stop acting like one." Spike said, with hatred.

Celestia nearly cried because she felt incredibly hurt. He had a point, she had never really been there for him. The other ponies in the room had never seen Spike this hateful before.

"Pathetic angelic filth. No wonder Lucifer hates you're kind, never spend time with family. Just going on fucking meetings that has absolutely no importance. I'd understand security, trials, military, but not the other fucking garbage." Spike said, as he rushed out the door and slammed it.

Leaving the ponies to collect themselves from their shock.
