Hello everyone, this is my first ever Fan-fiction. It is highly erotic in nature so reader beware. It will contains MF, MFF. It's pretty vanilla, but there will be some light Bondage. I hope you enjoy reading it as much as I enjoyed writing it.

O.K. I've made some revisions to all three chapters. Most notably I've expanded the climax ;p of chapter 2 as well as chapter 3 . the17thcollosus was right. I rushed the ending scene with the three exuberant youths. I was tired. I was so excited to share with you guys that I did it a disservice. I hope that it feels better paced. Chapter 4 is outlined and incoming. I'm considering expanding this into an AU... idk we'll see. Stay tuned and thank you for reading :)

Star Butterfly stared lazily out the car window, watching the the beautiful town of Echo Creek pass her by. Her window was open, and the warm air flung her hair in a flurry of blonde. Palm trees lined the street as they turned into the suburban neighborhood that they lived in. Generic homes lined sloping streets, arid dirt lawns peppered with cacti. Star spotted the Diaz household in the distance. The home stuck out due to the remarkable Mewni style tower, it rose far above everything else in sight. She loved it here on earth, the last 3 years had been an incredible adventure. She looked to her left, and smirked at the driver.

Marco Diaz was driving at least 5 miles below the speed limit. 'You could never be too careful while driving a car' he would say. It was humorous to her because, she knew for a fact Marco speeds. It was only when she was with him in the car that Marco would drive like a old lady with bad eyesight.

Star sighed, and did the usual mental comparison with her boyfriend Oscar. Oscar didn't give a single care, and sped constantly. He had a lot of tickets. She frowned. Oscar hadn't been to school today. In fact Oscar hadn't even seen or called or responded to Star's text messages in 3 days. She was getting quite fed up with it. Not a great way to start their 4th month together.

Marco turned down the music that was blasting and pulled into their driveway. He looked at her and smiled. Star smiled back and got out of Marco's used Volkswagen beach buggy. It was dark green, the board rack was rusted and the paint was chipping. It took Star three tries to get her door to slam shut. He had gotten it to impress Jackie, he had even spent a summer going to the beach with her and learned how to surf. That was when they dated. Star grimaced, she liked Jackie a lot and was surprised when their relationship only lasted 6 months.

Marco had told her that when he actually got to know Jackie, she didn't live up to the perfect image he had built of her in his mind. Star looked up at the beautiful two story house she called home, it's extra-dimensional add on sticking out like a jagged nail. She snuffled to herself following Marco inside, thinking that she was in a similar situation. The longer she dated Oscar the more she learned that the aloof bad boy, had qualities she didn't much care for. They barely even hung out.

Mrs. Diaz came out of the kitchen brandishing a large bowl of nachos, they were steaming from their recent cheese deluge. She stopped in front of the two teens in the foryar and held out the bowl. Mrs. Diaz smiled warmly "Marco! Star! Welcome home my loves, how was school?"

Marco cheered "Nachos? How did you know?" he asked as he snatched the bowl and headed for the stairs. "School was normal. No pop quizzes, no monster attacks. Although, there was this incident at lunch. Ferguson told the dirtiest joke and made Alphonso shoot milk out of his nose. Incredibly, it landed on Brittany Wong!"

Star laughed loudly, following Marco up the stairs. "I don't know Marco, I think a tantrum from Brittany is par for the course."

Mrs. Diaz rolled her eyes and said "Well, those should hold you until dinner. Which is at 7:30. Your father is barbecuing ribs. " Star and Marco hooted in a declaration of rib love.

The two finished their accent and headed down the hallway towards their bedrooms. Marco stopped in front of his door, "Hey Star? Do you want to watch a movie?"

"Absolutely! Let me go put my stuff away and I'll grab a movie from the pile that Pony Head sent me" Star performed a sloppy pirouette and skipped towards her door, her blue dress danced flippantly.

"OK, I'll get my couch ready for the Ultimate Cinema experience" Marco waved and shoved a handful of nachos into his mouth. He turn, and entered his room. Star finished her jig down the hall and reached her door. It was covered in wooden planks that patched to hole the new born Cthulhu infant had made in it. She giggled remembering how cute it was when it hatched. Too bad they couldn't keep her. Mrs. Diaz didn't appreciate having to replace all the furniture that lined the hallway. Mr. Diaz didn't mind though, he had made most of that furniture and it took no time at all to make more.

Star pushed the Blu-ray of "Attack of the Sea Lords" into Marco's PS4 and did a twirling dance back to where Marco sat on a love-seat sofa located at the foot of Marco's bed, It barely fit the two of them, but their closeness wasn't anything new.

Star looked around the room as the previews rolled. It had changed so much since she first arrived on Earth. The walls were covered in posters and certificates of achievement. Most of it covered the dark blue paint that gave the room a dark complexion. There was now a King sized mattress, that dominated most of the space in the room. Marco had a shelf of trophies which were occupied by several championship placings. *Marco is quite the skilled warrior, Star thought, He even bested King River in Mewni Mud wrestling. Which is saying something, because Mewni mud is twice as thick as Earth mud

She turned her attention back to the 50' flat screen that was mounted on the wall opposite of them, the movie had started and they sat in attentive awe as the violent movie opened with an incredible invasion scene. She didn't know how the main character was going to get out of it alive. The lead was played by Francisco Del Toya, a long time Hollywood action star. She bit her lip, the man was SEXY! *I guess I have a thing for tall dark and handsome...* Star thought as she stole a glance at Marco.

Who was staring at her! She averted her eyes back to the screen, her face feeling hot. Why was he staring at her? "UHH, Marco, why are you staring at me?"

Marco threw his head back and laughed, "Haha! You finally caught me, I like to watch you watch movies. You make the funniest faces when something crazy happens."

Star laughed and returned her gaze at the movie, trying really hard not to notice Marco in her peripheral. The movie was super gory which was her favorite. To Star's surprise in the middle of the second act, right before there was going to be a huge battle, Francisco's character started a steamy sex scene with his co-star Chloe Grace Moretz.

*Oh my!* Star thought *This is getting really good* Star shifted in her seat unconsciously pointed herself towards Marco, her knees touching his. She felt her face start to heat up, then cool suddenly as blood rushed towards her nether. *I am getting really turned on... I wonder if Marco is getting a hard on?* Barely focusing on the movie Star imagined Marco and herself, sweaty from a battle with Monsters, hugging in victory, an embrace that lasted longer than a friendly hug should.

Star closed her eyes, fully committing to her mental narrative. Daydream Marco whispered sweet nothings into Daydream Star's ear, as he passionately necked her. Dream-Star ran her hands through Dream-Marco's straight Latin hair down his neck looping around front to get a feel for his well toned chest. Using the mental memory of Marco's latest MMA victory physique Star made Dream-Marco start to remover her dress over her head-

"Star?" Marco snapped Star out of her daydream. She hadn't noticed she was fidgeting, rubbing her knees together, attempting to stimulate herself. "You're distracting me from the movie. " The sex scene was over and the screen currently showed Francisco disemboweling a poor Sea Lord grunt.

"Oh! Sorry!" Star blurted, face flushed, sweat beaded her forehead. "I'm actually not following this movie very well. I'm going to go take a shower before dinner. See You!" Star practically dashed from the room, and went straight to the bathroom, where she ripped off her clothes, turned on the bathroom ghetto blaster to Speed Metal, and jumped into the shower at full heat. She then proceeded to finish her fantasy, as well as herself.

Cloud Lounge Dimension

"Yeah, so I masturbated furiously for like, 20 minutes and had probably the best orgasm I've had in a while." Star, put down her drink and looked at her two Other-Dimensional Besties.

Kelly blushed even deeper than usual, adjusted her glasses and said "That. Was. So. Hot."

Pony Head threw her head back and laughed,"Damn guurrl, I didn't know you thought of Earth Turd like that!"

Star bushed."Neither did I. That movie really set me off." Kelly brushed a green lock out of her face and giggled "Well Marco has been training for a fight. I bet you get to see his chiseled bod, like, all the time."

It was true, Marco was training constantly for an upcoming MMA match. Not that he needed to. Years of fighting monsters had honed Marco into a very dangerous weapon. His matches rarely made it to the second round. Marco was training hard for this one because if he won, he was guaranteed a spot on Ultimate Fighter. Star was so proud of him.

She never really put much thought into the fact that Marco had turned his body into the perfect specimen these last few months. She was with Oscar, who could stand to put on a few pounds, and some muscle. He was basically a stick man. *There I go again, comparing Oscar to Marco. More and more Oscar falls short*

Pony Head nudged into Star and teased "If I didn't know any better, I'd say you've fallen for the Earth Turd!" Star blushed.

Kelly nodded "Yeah, I've about had it with Oscar too, he's not doing anything with himself. Has he even written anything new for his band lately."

Pony Head snuffed "I doubt it. STAR, girl, you gotta drop that skeez and get with the Earth Turd" Kelly fist bumped(tapped Pony Head on the nose) Pony Head and affirmed "I agree, Marco is choice. You'd better lock that down before he becomes a famous UFC star."

Star looked into her drink a thought about what her friends were saying. Maybe they were right...

Star had the wildest idea. She hummed to herself as she ran about the kitchen, putting the finishing touches on the bowl of Nachos. Mrs. Diaz nearly tripped over Star as she flew past, and jumped up the entire flight of stairs. Star Twirled gracefully down the hall and snatched up the Blu-ray that sat on a cupboard in the hall and continued towards Marco's room pausing briefly at the thermostat and turn it to sixty degrees.

Star had concocted this plan after her conversation with Pony Head and Kelly the night before. She wanted to test the waters and see if Marco had any interest in her.

"Marco!" Star kicked at Marco's door, as her hands were full, "Marco! Pony Head sent me a new Blu-ray. Lets watch it right NOW!"

Marco open his bedroom door, and gaped at star. This pleased Star immensely. She was wearing her hair in a ponytail, a black Tool tee-shirt that stopped at her bellybutton and dark blue 100% cotton short shorts. Her modest C cup breasts kept the tee from touching her tight stomach, showing off her hard earned abs. She usually wore dresses, so she bet Marco wasn't even aware that her ass couldn't be contained by such short shorts.

"Well, let me in!" Star beamed at Marco who stammered

"Y-yea, come on in, "

Marco scampered around his room, snatching cloths off of the floor, and quickly shoving them into the laundry hamper. Star ogled at him while he was distracted. He was wearing his gym shorts, that hugged his tight butt. He wore a tank top with the name of his gym on the back of it with a large "DIAZ" embroidered underneath it.

Star settled herself onto the couch and handed Marco the Blu-ray to put into the console.

This was no ordinary movie. This movie was specifically curated by Kelly and Pony Head. This movie was another action film, this time staring Chris Pratt and Zooey Deschanel . This movie was chosen because it had a rather racey, and lengthy sex scene in it. It was called "Revenge of the Wilder-beast from Underneath!"

"Pony Head told me that this movie is awesome" Start informed Marco as he sat down next to her. She noted that Marco was not looking her in the eyes. The hearts on her cheeks seemed to get redder, and they nearly touched her eyes when she smiled. Pony Head had told Star that she had 47 minutes to implement the plan.

The nervous princess looked at the clock, *10 minutes to go!* she thought. She shivered very noticeably, and quite genuinely. "It is really cold in here" she said," I'm going to usurp your body heat" sitting up and leaning into Marco's face. He blushed and blinked at her.

Star stood up, turned and grabbed the comforter off of the bed and sat in the space between Marco's legs, flung the comfortable blanket over the both of them and activated the recliner function, forcing Marco to lay back. Star fidgeted quickly and lay her head back on Marco's chest. She took his arms and wrapped them around her neck. She sighed loudly "MUCH, Much, better" she finished her sentence in a whisper. She could feel Marco's substantial package against the back of her ass. It twitched.

Ten minutes later, as forecasted Chris Pratt took Zooey Deschanel into a log cabin and started furiously kissing her. *This is hotter than the scene in Sea Lords!* Star thought. As the scene progressed, Star noticed her breathing had become heavy. She clutched at Marco's muscular arms located around her neck and breathed in deep through her nose. Marco smelled incredible. She wiggled, shifting her weight slowly from side to side, using only her hips. She could feel him start to grow immediately. She could also feel herself getting wet.

Marco's length stopped it's journey upwards at the small of Star's back. She let go of his arms not saying a word and leaned into him and started gyrating slowly. His dick fitting snugly between her cheeks. Marco's member twitched against her and Star inhaled sharply,

"Star..." Marco began, but Star shushed him and positioned herself higher on his chest, his dick sliding deeper into her rear. Still moving her hips she turned her head and nuzzled his neck breathing in his scent. He smelled of the beach. She nipped at his neck, leaving tiny bite marks where she struck. Marco's cock twitched again making Star gasp loudly. She arched her back and brought the tip of his bulge to her guarded entrance. If they were naked he would have penetrated her right there. Star prodded Marco against her moist shorts making small noises of pleasure.

Time seemed to stop as the two youths leaned into one another. Both of them on the edge of oblivion. Marco held his breath as he climaxed, his dick pulsating into Star's crotch. Both of them were breathing hard and neither moved as Marco's spunk soaked through his shorts, mingling with her dampness. Star planted a long kiss on his neck, "I'm sorry" she whispered and fled to the bathroom where she finished herself off.

It didn't take long.
