I'll only mention a few of the character's costumes, if I don't mention a costume for some characters then you are free to imagine what they're dressing up as

"God, we're like thirty minutes late now..." Scourge grumbled, he folded his arms over his chest and stared out the window of his passenger seat.

Fleetway was driving them from their agency's halloween party to their friend's party. The road that night was busy with halloween decorations and people trick-or-treating.

"Don't worry, they already know why we're late. Besides, it's gonna be dramatic to have you fashionably late." Fleetway assured. He was dressed as a character from a horror movie, specifically as the murderer.

The couple finally arrived at the club where the party was held. It wasn't too crowded because the girls only invited their old classmates to the party, so it was more of a private party.

Before they could enter, the bouncer outside made sure that they were on the list. Once their names were confirmed on the paper, the bouncer allowed them to come into the club. Fleetway opened the door for his wife and they both finally stepped inside.

"Oh wait– Scourge! Fleetway! You made it!" Rouge said while holding a microphone. "Guys, they're here!"

Everyone's attention were focused on the two that just arrived and everyone cheered.

"Fleetway! Hey, it's been a long time, man!" An old friend greeted.

"Fleetway! Scourge! Cool costumes!" Another old friend greeted them.

The couple were happy to meet their old classmates again. It was more amusing since everyone was wearing their halloween costumes.

"Scourge!" Sonic shouted with a microphone  from the DJ booth upstairs, he had requested the DJ to tone the music down for a moment.

Scourge saw him and he snickered, "you're ACTUALLY wearing that?!" He shouted back while holding his laughter.

"You may be the famous one out of everyone here, but don't forget that tonight I'm THE diva." Sonic pointed his finger at him.

"Sonic, get down from there!" Shadow screamed.

After greeting all of their old friends, Scourge and Fleetway went to meet the others who gathered in one of the longues. Fleetway noticed that Mephiles and Infinite were at the bar, so he decided to go there while Scourge stayed at the lounge.

"Scourge, I'm so happy you made it!" Silver got up from the sofa and hugged him.

Scourge was stunned. He was frozen in place when Silver decided to jump and hug him tightly. He did not expect his costume was going to be that cute. He finally wrapped his arms around the slimmer hedgehog.

"You're so cute."

"I wanted to try and change my look to be scarier but I didn't know how." Silver said as he pulled away from the hug, "so I gave up and just accepted that my yeti costume is cute." He chuckled.

"I'm so glad I can make it to the party." Scourge said with a playful smirk, and pulled the other closer.

"HEYYY HEY HEY HEY." Gadget suddenly ran pass between them, separating the two hedgehogs. "Nope! I'm the horny police for tonight! No horny!" He pointed his fake baton at Scourge.

"Gadget, what the f–"

"THE SENSATIONAL DIVA HAS ARRIVED." Sonic ran and hugged Scourge from the side. "You're lucky to be in my presence." He smirked and made Silver laugh.

Scourge, on the other hand, was annoyed. Mostly because he wanted to flirt with Silver but kept getting interrupted.

"Silver, come sit."

The twinks noticed that Mephiles came back to the lounge. Silver nodded his head and followed his fiancé to sit on the large sofa. Shadow, Infinite, and Knuckles also came to the lounge seat.

"Aand there goes my chance." Scourge groaned.

Sonic let go of him and he went to Shadow instead. "Shadow! The music's so good right now, let's go dance!" He bounced energetically and pulled on his boyfriend's hand.

"Okay okay." Shadow chuckled and let himself be dragged to the dance floor where they also dance with their old frienda.

Amy and Blaze finally arrived at the lounge with a tray of a few bottle of drinks.

"God, Sonic's already acting like he's drunk and he's only had a glass." Amy commented.

"He's probably just happy that we get to hangout like this again. I mean, when's the last time we had a party with all our classmates?" Knuckles said while pouring himself a drink.

"I agree with Knuckles, so far it's been so fun and I had lots of candies already." Silver giggled.

"Oh I had like three bars of chocolate already." Infinite said.

Fleetway came back from the bar and handed his wife a drink he specifically ordered for him.

"Honey you look annoyed, you okay? We just got here." Fleetway asked worryingly and floated down to sit beside him.

"It's fine. Thanks for the drink." Scourge pouted and took a sip.

"Oh! He wanted to flirt with Silver but I stopped him." Gadget raised his hand.

"WHAT–"

"Calm down, I didn't even get to do anything." Scourge rolled his eyes at Mephiles.

"THAT DOESN'T MAKE IT BETTER." Mephiles shouted and Silver just facepalmed.

"Aaanyway, come on Finny. I wanna dance too!" Gadget got up from the sofa and pulled his boyfriend's hand.

"Alright, let's go." Infinite smiled.

Blaze got up to join them, then Amy also stood from her seat.

"Hey, don't be so bitter tonight. It's a Halloween Dance Party. Rouge, Blaze and I worked hard to plan this, so just have fun!" Amy said to them with a bright smile before leaving to join her girlfriend on the dance floor.

The only ones left on the lounge were Scourge, Silver, Fleetway, Mephiles and Knuckles.

"Aren't you gonna look for Rouge?" Fleetway asked to the echidna dressed like a pirate.

"She's currently 'girl gossiping' with her old gossip group, so I told her I'd wait here." Knuckles shrugged then took another sip of his drink.

Suddenly, the crowd on the dance floor were repeatedly shouting 'Miku'. They turned their heads to stare at the crowd and saw their friends cheering for Sonic who took over the spot by breakdancing. Shadow looked proud.

"I haven't seen Sonic move like that since our high school days." Scourge chuckled.

"Yeah, I can't believe he can still spin on his head." Knuckles laughed.

"Silver, do you want to– HEY NO NO NO." Mephiles looked away for a moment and Silver was already drinking straight from the bottle. "USE THE GLASS." He pulled the bottle away.

Scourge laughed at them while Fleetway and Knuckles looked impressed but worried at the same time.

"I don't care, this is the only time where I have a bottle of alcohol right in front of me since you never have one stocked in our pantry. Let me have another!" Silver demanded.

"Yes, drink Silver! Finish the bottle!" Scourge cheered.

"Hey, you do you, twink." Knuckles raised his glass at him.

Sonic suddenly came back to the lounge, not even breaking a sweat from the breakdancing.

"Hey guys, I wanna drink." He took a bottle and poured it to his glass. "I can't believe I just took over the floor like that, did you guys see me?" He asked before taking a long sip.

"See? Even Hatsune Miku use a glass! You use it too!" Mephiles pointed and almost made Sonic spit out his drink to laugh.

"I haven't seen you dance like that in so long, that was honestly hot of you." Scourge complimented.

"Thanks. Uh– hey, Meph, what was that for?" He chuckled.

"Silver wants the whole bottle to himself." Mephiles grumbled.

"I mean, when is he gonna get another chance to drink a whole bottle? Just let him."

"See?! Hatsune Miku said I can have it!" Silver pointed and Mephiles facepalmed. Scourge threw himself back from laughing, Knuckles covered his face and laughed too.

"Well, Hatsune Miku is needed on the dance floor. I'll talk to you soon." Sonic giggled and left to go back to dance with his friends.

Shadow spotted his boyfriend coming back from the lounge and he caught him in his arms.

"There you are, my cute little idol." He flirted.

"Hehe, my handsome cowboy." Sonic blushed and gave him a peck on the lips.

As the party continued, Silver ended up drunk and kept flirting at Mephiles as if they weren't engaged already. Mephiles thought he looked cuter when drunk, but now he had to make sure that his fiancé is safe with him while he's in that state.

Rouge came back from her gossip group and finally sit down with her boyfriend to enjoy some drinks.

Scourge continued to drink and got a little drunk, he almost spent the rest of the party just making out with his husband and asking him to fuck. Fleetway had to hold him down so he don't suddenly jump on his lap and fuck himself on him.

Sonic eventually got tired from dancing and asked Shadow to take him back to the lounge so they could rest. Shadow couldn't drink because he took his medicine, but he always poured one for Sonic whenever he asked for it.

Gadget went from being the horny police to the horniest police in the club, Infinite kept teasing him and only gave small kisses to the poor wolf.

Amy and Blaze were being the best host of the party, they kept checking om their friends and made sure that everyone was having just as much fun as they do.

The party was chaotic, the music was loud and the lights were dim with a bit of flashy colorful lights and thin fog to set up the mood, but overall it was the best party that they ever had in forever.
