Halloween in Langley falls was a great holiday for everyone. Time to go treat or treat for free candy and decorate the house with spooky stuff and be in the spirit of things, even someone who is starting to be a little bit old for that, could be put down in his crusade for the sugary needs and costumes.

That, someone, was Steve Smith, 14-year-old nerd of the Smith household.

"Ahh Halloween, how I love this time of the year. I spent months working on the perfect robin costume just for this" He said starting to come downstairs.

The costume he chose was a Robin that he felt would be the most representative and the best mix of all the DC Robins, aka the Cartoon Network Robin with gelled up hair, green spandex pants, and the best damn ass-kicking shoes around.

"Who cares about the others anyway? I'm still young enough to go trick or treating. This is just something you can't let go that easy, and if anyone makes fun of me I throw them a trick" Steve mused, bag in hands. He wonders if his friends would be somewhere perhaps.

'I think I'll call them and ask if we can meet up.' Steve thought as he reached into his yellow utility belt, a special collector's item he got and pulled out his phone.

While the costumed sidekick boy stopped to make his call, the attic door opened, and out came someone rather "special" to Steve.

"Oh hey, Steve!" Roger said to him.

'God damn it...'

Steve didn't want to look Roger in the eye after what happened in the attic on that one rainy day, he was still trying to come on terms with the...well the intimacy that happened between the two.

"I'm busy Roger"

"Yeah I can see that but just hear me out" Roger said but Steve ignored him as he focused more on calling his first friend, Snot.

"Listen Roger I'm going trick or treating with some friends, so I got no time to listen to some silly idea on how to spend your holiday totally drunk''

"I don't get drunk every holiday! Just the ones that involve booze as a tradition, and unfortunately booze isn't traditional on Halloween." Roger said as Steve rolled his eyes as Snot picked up the phone.

"Hello?" Snot said as Steve smiled at his answer.

"Hey, buddy! So, are you ready for Halloween? I bet you and the others got some badass costumes"

"Oh. Sorry, I can't go trick or treating tonight. I've got plans." Snot said as Steve lost his smile.

"What? But we always go trick or treating together, You, me, Toshi, and Barry every year." Steve said as Roger stopped talking and listened to the lesson.

"Well Steve, this might not be easy for you to understand so I will be blunt with you...maybe we are a little too old for that you know? Trick or treating is more of something you should do until your twelve or something. You should be trying to get into Halloween parties for our age, not that it's easy but you get it right?" Snot finished.

"No, I don't get it! It's the only night where you get candy for free and not have to worry about being rejected at parties!" Steve said.

"Steve! Halloween is for little kids who go out in costumes and ask for Candy? Do you really want us to go out dressed up as cartoon characters and whatnot just for the heck of Candy? We should be looking up to those adult parties to make us feel more like men. I don't care if it won't be easy, but we had a good run, since we were little silly kids we did this but...if you want to go trick or treating? It better be at a party, drinking beer and flirting with girls. That's what we should be striving for now"

"Do Barry and Toshi feel the same?" Steve had to ask.

"Well Barry is easy to go along things but you know how Toshi is...actually no you don't, neither of us does because he speaks Japanese"

"Well did he nod yes or shake no?" Steve asked him.

"It doesn't matter, Steve. The point still stands that we are too old to be trick or treating, so I'm sorry but you are going alone tonight." Snot said.

"Don't tell me about you! Got into something better" Steve scoffs thinking he is lying.

"Actually yes. We heard that Vince Chung is gonna have a bonfire in the woods and anyone is invited if you bring booze or full-size candy!" Snot said with excitement.

Though Steve wasn't in the same boat since the last Halloween he went to Vince Chung's bonfire, Toshi hunted him down to kill him and Akiko turned him down for a nine-year-old that could dance like a professional. That was without a doubt, one of his most embarrassing Halloweens ever.

"You mean the guy that teases us because of sleepovers and gave us swirlies in the bathroom with one of our other worst bullies? Fine, you know what? I hope this is all just a trap to prank you" Steve ended the call and looked hurt "Great...now this shit happens, why can't I just enjoy the things I do without being judged?"

"Because this is reality Steve, not some silly cartoon show. But hey! Don't be so down in the dumps, how about I go with you on the candy hunt?" Roger offered.

"You want to go trick or treating with me?" Steve asked him.

"Why not? This holiday was practically made for someone like me." Roger said.

The geek thinks for a moment, should he really let Roger go with him? His friends were off the board now but things could get weird again with the alien. Going alone though would make him feel kind of a loser.

"Ugh...Fine, you can come but do you have a costume for Halloween ready?"

"Steve, I always have costumes ready. Fictional or not, I've got costumes you wouldn't believe." Roger said before heading back up to the attic. "I'll be down in a few minutes."

"Fine but hurry, the houses with the full-size candy bars run out quicker than others!" Steve said as he began waiting for the alien to pick his costume, hopefully, nothing like a sexy female character to mess with him.

*SIGHHHHH*

"Man...things sure are changing around here. I bet even the fellas are going to stop wanting to hang out with me, the Halloween will only be the start" Steve said, sad.

As Steve sat sadly and talked to himself, he didn't realize that the few minutes he gave Roger to get ready passed and the alien had come back with his costume on.

"Alright, Steve. I'm ready to go." Roger said as he stood behind Steve.

When turning around, Steve's eyes widened a little when seeing what Roger was wearing.

"Wait...is that what I think you're wearing?"

Standing before the sidekick dress boy was Roger in a chin-length auburn wig, square glasses with no lenses, a baggy and thick turtlenecked orange sweater that hid a large chest(Jennie Gold size), a red skirt, knee-length orange socks, and black Mary Jane shoes.

"Behold Steven, the Scooby-Doo classic costume. Velma Dinkley." Roger said as he gestured to the costume before pulling it a choked that matched his skin tone.

"R-Roger?" Steve started to sweat.

"You like it? I worked on this baby for some good while and took some inspiration through the fanart made on the internet for some details. But I'm a bit worried, can I ask you a question?" Roger looked at him funny.

"W-What question?" He was already nervous.

"Do you think my butt looks too dump truck thanks to this costume?"

Roger\Velma said, bending over slightly letting Steve see his huge grey alien ass that looked to be way thicker than last time he dressed up as Laura Vanderbooben, he sure looked at the Velma fanart alright.

"Uuuum, y-yeah?" Steve said with a blank mind, becoming entranced by the ass again.

"Perfect! Got the costume down to a tee." Roger said as he put the choke on and turned back to Steve. "Now let's get some trick or treating done, huh Steve?"

Steve shook his head "I...Whatever. Let's go before the good stuff gets wiped by any fat kids who are always begging for more"

"Yay! Sugary night! Roger was the first to open the door.

Over the next 2 hours, Steve/Robin and Roger/Velma had hit the neighborhood up and down for all the candy they could get. From fun size to full size and nougat to artificial, the haul they got was something to be envied.

"Damn! We actually got a lot here" Steve said happily.

"All that ks to my costume I bet" Roger said.

"Never understand why my family is the only who seems to realize you're an alien with a wig but everyone else seems to be aloof to it"

"I'm just that good at disguises." Roger said as he flicked the wig hair back.

"Maybe we have enough time to go home?"

"Oh cmon, I'm sure we can..."

Roger then stopped walking for a moment and looked at the left in their path founding something interesting.

"Hey, Steve, how about we go to that one mansion before going home?"

Steve turned around and took a look at what he meant, then it was in that moment he saw what appeared to be an abandoned sort of old house that shows up in classic horror movies.

"Ahn...That doesn't look safe Roger" Steve looked unsure.

"Come on, it's probably like that because the owner doesn't fix it up around this time of year to make it scarier. Plus they must have those huge candy bars you wanted." Roger said as he began leading Steve to the house. "Come on, it'll be fine."

"Y-Yeah! I'm a man after all, not a kid. This is gonna be simple, just a quick grab and go" Steve gulping down.

"That's the spirit, now let's see if this old hole has at least something well worth their sugar"

Heading through the gates of the haunted-looking house, Steve and Roger made their way up to the said house and knocked on the front door.

"Trick or treat!" Roger said as he and Steve waited for an answer.

They waited in turn for twenty seconds but no one came.

"Weird...nobody came" Roger said rubbing his chin.

"Maybe they are not home you know?" Steve started to act cowardly.

"On a Halloween Night?"

"They could be at a neighborhood party or on vacation." Steve countered.

"C'mon! Let's get inside and check it out. This is a Halloween chance in a lifetime, it will be awesome" Roger said reaching for the door.

"What? No! We can't just go in, this place is probably locked away! I'll show you." Steve said as he reached for the doorknob but as he turned, he found it wasn't locked at all.

"Well, what do you know? Maybe they forgot to lock it. Trust me it happens more often than you think" Roger smirked.

Moving past the teenager, and giving a subtle sway in his hips, Roger walked into the house as Steve tried to stop him but he had fallen under the alien's hypnotic spell. Again.

'No. Please, not tonight.' Steve thought as he tried but failed to look away.

"Come on, Steve. They may have some candy hidden away inside." He called out to Steve.

He sighs deeply "I hope I don't regret getting inside some weird-ass anomalies in there"

"Don't be a scary cat. I protect you, big baby"

Begrudgingly following "Velma" inside, Steve gently closed the door behind him and followed "her" through the house.

The inside of the house was old and just like some old movie where a slasher would come at any moment. Roger Aka Velma walked skin close to Steve all the time like he was a girl in need of protection.

"We should probably head to the kitchen and see if the candy is there" Steve said as he looked around for it.

"Yeah the kitchen is the best-UPS!"

Roger clumsily fell to the floor and dropped his glasses on the floor just like Velma.

"Oh no! My glasses"

Getting on "her" knees, "Velma" began to feel around to find with "her" ass in the air in front of Steve.

It casually moved left and right with a subtle jiggle letting him see the red thong.

"R-Roger! Cmon, those glasses don't even have lenses" He said without breaking eye contact with the booty.

"I still need help finding them, they tie the whole costume together!" Roger said he shook his ass a bit faster, faking to find them even though he could see them under the couch.

That vision made a blood pump through Steve's "Staff" which was more prominent now thanks to the costume. Somehow that shapeshifting ass expansion always got to him.

"Ugh, fine let me see"

Wanting to not be swayed by the large ass any longer, Steve moved Roger aside to find his Velma glasses for him.

'I swear the things that I go through for Candy. I sure hope Snot is having a bad time wherever he is" Steve got on four looking for the glasses.

As Steve searched the floor for the fake glasses, Roger had grown a smirk while his back was turned as things were going exactly how he wanted them to be. See back at the house, Roger had planned something special for him and Steve to do tonight but it was derailed so Steve wanted to go trick or treating. So with some slight quick alterations, Roger came up with a new plan.

'Just a little push and the last nail will be put down' Roger then starts to mess with something hidden on the choker.

A small button was pushed and Roger gave a few whispers to test it out.

"Testing testing. Jinkies" Roger whispered as his voice was now exactly like Velma Dinkly. "Perfect."

The stacked cosplayed alien walks slowly towards Steve and decides to surprise him with his new voice, first of all, he covers the geek eyes with his hands.

"What? Cmon Roger, we don't have time to play around"

"Guess who..." Roger said in his ear.

If his eyes weren't covered, they would be seen as dinner plates as Steve jolted right as he grabbed the glasses and slowly sat upright.

"My glasses!" The voice said as the hands were taken from his eyes and allowed Steve to see Roger taking the glasses from him. "Thanks, Steve."

"R-R-Roger?" Steve stuttered out.

He was not going crazy right? That was still Roger but his voice...was that of Velma? The one from the old cartoon shows?

"Is something wrong Steve? You seem like you saw a ghost" Roger\Velma makes a cute and clueless face of Steve's reaction.

"I-I-I-I'm FINE!" Steve shouted as he stood straight up. "He's fine!"

"Looks like no one is here, what a mystery right?" Roger\Velma said, noticing the boner on his crotch area.

"Um...ye-yeah. Makes you wo-wonder where they went." Steve said, unintentionally playing along with "Velma."

"How about we put the candy on hold and find out? Maybe there's some clue around the house that could tell us." "Velma" suggested as she looked around the house, lit by the outside moonlight.

'Fuck! That voice is doing things to me' "Maybe upstairs?" He tries not to look too much at "Velma"

"Great idea, let's have a look." "She" said with a nod as she went to the stairs, shaking her ass back and forth as Steve followed.

'Oh god, is it happening again?' He thought in surprise as he subconsciously followed "Velma."

'Right on track.' Roger thought as he headed towards the bedroom, where a nice Queen sized bed was waiting.

There was no way to hide it from him, Roger knew how much Steve was now craving "Velma'' Even more now that he added the voice, only making it sound more real and add to every nerd's dream to have their favorite cartoon girl in real life.

"This looks like a good place to look, shall we?"

Stopping behind her, Steve looked around and realized that they were inside the master bedroom with pristine royal blue sheets and black transparent curtains hanging over it. Nice wooden dressers and a large window casting moonlight over the bed.

"Oh! We're looking here first?!" Steve said in surprise, dropping his sack of candy to the ground as he looked around the room.

While Steve was busy looking around the room amazed by how beautiful it was even though the rest of the place looked ready to crumble. Roger slowly closed the door and locked up the key and all.

"Oh you know how these things go, the bigger the room...the more stuff can happen here" "Velma" Said with seduction.

"Yeah, you never know what could happen in a room like this." Steve said without thinking as "Velma" walked to the bed.

"Maybe we should just take a little rest" Roger started getting in a position.

"A rest? But we haven't fou-" Steve said as he turned but paused when he saw Velma, laying on the bed with "her" legs crossed with a hand on "her" hip and the hand on "her" face with the elbow on the bed.

The skirt of her costume was pulled up to show "her" thong hugged hip while "Velma" gave "Robin" bedroom eyes.

"Yeah, don't you think we've earned it after all the ~hard~ work we've done tonight, Robin?" "She" said to him as "her" eyes fluttered.

"What...What are you doing?" Steve gulped down, erection getting harder.

"Who me? Nothing much, I'm just worried about your well being. All those houses and the heavy bags of Candy, maybe it's time to lay down and...ravish said sweets" Roger said with innuendos

This was it, this was the same feeling he got from that drinking truth or dare game. Though no longer dulled by alcohol, it was screaming at him and his lower half to go to Roger.

"I-I-I-I gu-guess we can." Steve said, having forgotten that he dropped his large sack of candy, and walked towards the bed.

"Excellent. You will love it, this bed feels super soft like...jiggly pudding"

Roger then changed position, laying on the bed with its chest against it, letting Steve see more of his ass, almost like he was ready to get on four if he asked.

'Comes on, take the bait, Steve! You don't know how much of what we did is still on my mind!' Roger thought with a bit lip, thinking back to when they first had sex.

Not that Roger would admit it, Steve was one of the best sexual partners he had in decades, and do not want more of it when they could have more, it would be a crime!

"Roger...are you seducing me?" Steve looked at him suspiciously "That Velma's voice is sus"

"And if I was, "Robin?" Would you have such a problem with an innocent mystery solver like me being attracted to such a strong hero like you?" "Velma" asked as she looked back at him.

"Well...As a hero, I need to pay attention to all kinds of crimes. And it appears to you! Have been too naughty" He got closer.

"Velma" Gasps in surprise "Me? Or I would never try to get between you and the law"

"Well from what I've seen tonight, you have been very naughty tonight. Invasion of privacy, home invasion, and seduction." "Robin" listed off as he finally reached "Velma." "I'd say you've got quite the serious rap sheet."

And just like that the hand of justice had descended...right on top of "Velma" phat left ass cheek, with such force it made it jiggle quite a lot.

"Oh!" "Velma" shouted in surprise, liking the rough slap to the ass.

"You little bitch, I know this nerdy exterior is just hiding how much of a perv you really are" Steve said, slapping the other cheek.

"Oooo! Like you're one to talk, you're into this as much as I am! Now drop the good boy act and keep spanking me!" "She" said as Steve kept slapping her ass.

Anyone who got closer to the abandoned house at that moment would hear the sounds of moaning at a high pitch thinking it was a banshee, and soon a horror theory was created from that.

The house really was haunted and anyone who came by it turned tail and ran away as fast as they could!

"Little sluts like you are always going around taking innocent bystanders to the bad side"

Steve dropped some of his weight on "Velma's" Back and started rubbing his raging boner on the soft ass mounds. The skirt being pushed up revealing more skin.

"A hard lesson needs to be taught" Steve grinned a bit maniacally. Like he was telling himself this was normal.

"Oh my! Are you gonna beat me up with that big weapon?" Roger made sure to use the new voice and make the most of the passive type of girl.

"You beat your criminal ass I am. Get ready cuz I'm a master with my staff." Steve said as he grabbed the gray hips.

Held onto Velma's body and turned her over to him before the teen started to french kiss her as their bodies rubbed against each other. Roger saw that Steve was into it so things were about to heat up, in this case not for booze.

"Your mouth tastes like Candy, did you take some of it when I was not looking? Ohhh the crime just increases" Steve said between laughs.

"Try taming me if you must, but all my secrets are locked down below" "Velma's" Said rubbing his cheek.

"Really? Well lucky for me, I'm good at picking locks." Steve said as he reached up to her ass to her thong, hooking a finger right in the middle. "Found the keyhole."

Meanwhile back at his house, Stan was still going with the whole "My house decoration is scarier than all the others" Sort of deal. Francine came downstairs dressed up as a blonde-haired Elvira.

"Stan do you think Steve is coming home soon? Normally he doesn't take this long" She asks worriedly.

"Don't you worry your head, honey. Steve is just going around asking for candy like he is still ten years old or something, he comes around with his friends like always"

Thinking he knew his dork son as well as he did, Stan went back to decorating the house as Francine had to agree with him while adjusting her standing hair.

"I guess you're right, Stan. And it does make me feel better that he's at least not alone tonight." Francine said as she went to the kitchen for the candy to give any more tricks or treats that came by.

"Yeah, though I wish he outgrows that trick or treats phase and...I don't know went to an actual Halloween party full of booze and bad decisions"

"Maybe get laid by a confused drunk girl?" Francine laughed at her joke.

"Haha! Yeah, that kid is so hormonal sometimes it's like he would stick his banana in anything"

As the two Smith adults laughed at the notion of Steve "sticking his banana in anything," they were unaware of how true that was when he already stuck it in something large, gray, and strangely sexy.

"AHN! AHN! AHN! Ahn N! Fuck! Ohh shit!" "Velma" Screamed loudly.

"Robin" had grabbed the criminal "Velma" From behind and attacked the stacked bitch from behind like a dog. Pounding his stick of justice in it, deep and hard...multiple times.

"We can add noise violation to your rap sheet too!" "Robin" said with grit teeth as he kept "serving justice."

Funny how Steve didn't seem to hate this as much as he thought. Being sober he thought for sure this would crack his pride and self-esteem...Nah he could lie, this felt weirdly amazing

'Oh god, it's all coming back to me! This feeling, this tightness! I'm starting to wonder why I didn't fuck Roger when he came on to me before that night!' Steve thought as he reached up to "Velma's" sweater and groped her... 'No bra, either! He wanted this as much as I did!'

"Oh, Jinkies! Jinkies! Yes, more!" "Velma" said as she lifted "her" sweater up and freed "her" breasts, holding "Robin's" hand over the right one!

"You're a bitch Velma. A horny slut urging for the seed that I have and you want it all inside of you, allow me to fill you up with punishment" Steve speeds up.

"Yes, yes! You solved the mystery! Now give it to me!" "Velma" screamed as "she" began to push back and forth against the rhythms of his thrusts! "Fill me up, fill me up with you hard, hot justice!"

"AHNNNNN!"

With one last mighty thrust, Steve exploded his magnum opus deep inside meant to drain his balls.

"JINKIES!" "Velma" howled as loud as "she" could as "Robin" pushed her into the bed as hard as he could, making sure his cum got as deep as he could get it!

He wanted to do just like those porn videos he watched and make this woman's stomach bloat with his cum!

"Ooo fuck~..."

It splurted, gushed, oozed, you name it. Steve was never able to blast a load of this size since after that one night with Roger even jerking off became weird for him.

'I suppose to fix the problem, you have to face the problem. Does this mean I can only get off to Roger?' He thought as he slumped on top of the gray-skinned "woman," feeling months of release drain in one amazing go.

'Or maybe I'm just too worried about this being gay...huuuuhhh' "I'm pooped''

Finally feeling his stream shit off, Steve made them both turn to the side and pulled his cock out of the alien's ass.

"Something tells me I can get out of good behavior now?" "Velma" asked.

"I-I didn't say that but...parol with me giving scheduled checkups might work." "Robin" said as he caressed "her" thighs. "And a possible cavity search in case you try to hide anything inside your body."

"Oh! I think that would be a great time to spend time together ``''Velma" smirked "Should we go back home or get ready for round two?"

"Hmmm...round two. But only after a quick refuel with some sugary treats." Steve said as he looked at his dropped sack of candy.

"Yeah, I'm sure your parents won't mind the hour. After all...you are the man right?" "Velma" said, making sure to rub his ego.

"Indeed!" Steve smirked before eating some choco balls.
