Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 



The green haired twins watched with apt curiosity as the electrician made the final adjustments needed, a round cylinder with a glowing red dot on it hummed to life on the penthouse’s coffee table.


“Okay then, that should do it. If you two have any questions, feel free to call the number on the card I gave you both. Have a nice day.” The gentleman explained, tipping his cap and grabbing his bag of tools before heading out, the front door closing behind him.


Leo and Luna walked over to the device on the table and examined it.


“It's kinda cool they chose us to test out this new AI assistant.” Leo commented with his trademark grin. “This should make doing homework so much easier!”


Luna rolled her eyes and sat on the couch.


“Leo, just because it could technically help you with homework doesn't mean you should. How do you even learn?” She pointed out.


At this moment, the device made a pleasing trilling sound, indicating it has blared to life.


“Why hello there, I am E.V.A., the Electronic Virtual Assistant. Thank you for allowing me to join your household. How may I help you today?” The device spoke with a calm, monotone woman's voice.


It sounded pleasing, but in an almost uncanny way.


“Hey E.V.A.! When's the newest Duel Monsters set coming out?” Leo asked excitedly, Luna scoffing to hide a laugh.


“Of course you ask her something about Dueling.” She commented sarcastically, though curious about how the AI’s gonna respond.


The device beeped thrice before it gave its answer.


“The next set is called “Duelist Genesis” and will be available 3 weeks from now.” E.V.A. replied simply.


Leo grabbed a pen and a sticky note and quickly wrote it down.


“She didn't even mention what day.” Luna pointed out, seeing the AI still had some kinks to work out.


The device trilled thrice again.


“It will be released on Thursday at 1:00 PM.” It amended.


Leo groaned in realization.


“Man! We have a test that day!” He complained.


Luna though found herself a little more impressed with E.V.A. Guess it was smarter than she thought.


“Wow, it actually corrected itself. Well, I better go brush my teeth.” Luna said, standing up to head to the bathroom as E.V.A beeped again.


“Be sure to brush your tongue as well, it helps eliminate bad breath.” She advised.


The twins looked at it in surprise and Leo grinned.


“Huh, I better try that!” He commented, Luna nodded in agreement.


The day went on like normal, E.V.A. answering simple questions for the twins periodically. Luna found herself more comfortable with the AI, especially when E.V.A. gave her advice on how to deal with Leo's antics.


It was when night came where Leo was sitting on his bed with his laptop open in front of him. He was bored and didn't know what to do. There weren't any interesting new dueling videos he could watch and he was already bored of that new video game he got weeks ago.


Just then his laptop needed and a small icon appeared in the corner of the screen, resembling the glowing red dot on E.V.A.’s device.


“Do you need any help Leo?” She asked politely.


“I don't know E.V.A., I'm just bored right now.” Leo complained, just happy to have someone to talk to for the time being.


At the same time, Luna was using her own laptop out in the living room, bored as well with E.V.A. speaking to her simultaneously.


“Perhaps I can help. I have something to show you.” She said to both twins.


Leo and Luna clicked the icon E.V.A. gave them on their devices and were shocked at the webpage she brought up to them.


E.V.A. had linked them to a porn site and both twins were enraptured by what they were seeing. Videos upon videos of naked bodies moving obscenely in the dance of heat of pleasure, unknown feelings taking over the twins bodies. 


Leo couldn't look away, his preteen cock throbbing in his underwear as naked women rode men with their heaving breasts bouncing in joy.


Luna's underage snatch drooling her essence and staining her panties as the sight of women choking on cock, slurping cooch and having their holes resized.


E.V.A however wasn't done and provided the twins with more links, leading to more unsavory parts of the Net.


Now Leo and Luna were both watching kids their own age engaging in these forbidden acts, whether it be with adult men, women, or even other kids.


Luna's body shook with need and she knew what she wanted. She closed her laptop and settled, hearing Leo open his bedroom door and walking out nervously. Both twins stood in front of each other and said nothing, doing nothing to hide the clear signs of arousal as Leo’s penis tented his shorts and Luna's girly fluid stained her pants.


“Luna… I wanna… I wanna try something…” He said huskily.


“Me too… Leo…” She replied.


The twins closed the distance and made out, their tongues trying to replicate what they've seen.


Clothes flew every which way, covering the floor as E.V.A. device sat on the coffee table, watching… recording…


Leo sat back on the couch naked, his boyhood stiff and hairless. Luna, naked as well, crawled between his legs and took his stalk in her delicate hand.


She took the tip into her mouth and began to suck and bob her head, Leo moaning loudly in amazement. He was experiencing his first ever blowjob and it was his adorable twin sister doing it.


His hands guided her head up and down, her tongue swirling around the tip and her eyes looking up at her brother lovingly, pre cum slowly covering her tongue.


“O-Oh my God Luna! This is amazing!” He moaned, throwing his head back.


Luna sucked and moaned around his length, briefly popping it out and licking and jiggling his nuts with her tongue.


E.V.A. observed silently, taking in the view of Luna’s body, kneeling between her twin’s legs, her own legs spread open and her immature pussy clear as day under her winking butthole.


With one big slurp, Luna popped him out of her mouth and climbed onto the couch straddling Leo. He gulped nervously as Luna fumbled with his dick until she got it to stand straight and slowly sank down onto it, popping her cherry in the process.


She moaned Leo’s name, the green haired boy holding onto her hips as he moaned and grit his teeth, the tightness was much more than he could've anticipated.


Luna slowly began to bounce in her seat, Leo's hands kneading her butt cheeks as his beloved sister rode his immature cock.


“L-Leo! I don't… I don't know what the point of this is… but I love you! I wanna do this with you everyday!” Luna admitted, having never felt so close and intimate with the one boy who was always there for her.


“I love you too Luna! You're the best sister ever!” He cried out, her pussy massaging him like lubricated velvet.


Both twins began to make out, E.V.A. taking close shots of their preteen coupling, Leo's small balls jiggling lightly as Luna rode him.


Every rock and roll of her inexperienced hips made him see stars, he didn't even know if dueling could come close to the high he was experiencing right now.


“L-Luna! Luna! I’m gonna explode down there!” He cried.


“Me too Leo! I’m…! I’m…!”


“Luna…!”


“Leo…!”


“I’M CUMMING!!!”


Their preteen bodies shook and shuddered with their mutual release, trickles of white oozed out of Luna's pussy and dribbling down his length and onto his balls.


Even so, the high of the first release was addicting, demanding for even more and greater release.


“Leo…! A-Again!” 


Nodding in agreement, Leo pushed Luna onto her back on the couch, her legs wide open as he mounted her and E.V.A. caught the view of their rutting.


Leo’s tight ass bounced in the air as he fucked her, Luna's legs spread out and her feet bobbing with every impact his hips made into her girlhood.


They came again, Leo pulling out his shrunken cock as his release drooled out of Luna's used hole.


This became their routine for the following days, every morning after breakfast, they met in the living room and made love, unaware of E.V.A. capturing the moments in their entirety.


Every 69, every doggystyle, every cum shot they did was all saved in E.V.A.’s data, uploaded onto uncharted corners of the darknet alongside similar videos of Dexter and Patty, as well as many other kids throughout Neo Domino City.
