Okay. Here I go. I love the Twins. They are awesome. I've wanted to write a twin-centric fic for a long time, but for some reason I couldn't do it. Sunstreaker and Sideswipe are twins. They are one spark that has split. Therefore, for them to bond, they must find another spark that will satisfy their broken spark. Make sense? .5+.5=1. 1+1= Bliss. So, while this fic is a threesome-centric fic, it was vital for me to do it this way. There was no way I could give the twins separate girls. To me, there would have been too many sparks running around.

Sunstreaker stood apart from the group. He was never really a part of the group to begin with, but this time he was physically separated from the group.

Sideswipe brushed his spark, sending him feelings of excitement. Sunstreaker smirked as the 'going' group folded into their alt-modes and took off for the landing site. He knew what Sides was excited for. Femmes. Apparently, from the lightning fast rumors that circulated the base, there were four unattached femmes on the ship. For mechs who hadn't seen or interfaced with a femme in many hundreds of years, it was exciting news to say the least.

Sunstreaker was excited also, in the interfacing department. He and Sideswipe always worked together to get the femmes. It was Sunstreaker's job to look handsome and entice them with his body. It was Sideswipe's job to look like a friendly mech. Together, the combination was nearly perfect. Of course, they never could agree on what to do with them afterwards. Usually, Sideswipe wanted the femmes to stay and start a relationship. Sunstreaker couldn't wait to see them walk away.

But, the femmes were usually scared enough of him that they would leave of their own accord. Sides was better at hiding his need to kill. Sunstreaker could not care less about hiding his need to shed energon. He was going to do it, whether he was on the battlefield, or if he was in the gladiatorial ring. It was also no secret that Sunstreaker was only an Autobot because he was loyal to Sideswipe, who was loyal to Optimus Prime.

Sideswipe wanted Sunstreaker to intercept the incoming Autobots. He was going to put on his 'handsome and charming' face and pretend like he cared about those around him. At the very least, he was going to pretend like he didn't want to actively kill them. If they didn't scratch him, he wouldn't scratch them. That was the way it worked.

Internally, Sunstreaker smirked, at least Optimus had the insight to send the most handsome mech in the Autobot army to greet the femmes. He would certainly smile and look inviting for them. But, the mechs on board had better watch out; he was in no mood to put up with talk of their 'conquests' the femmes on board. He and Sides had gone without interface for a long time. And that made him angry. Although, what didn't make him angry these days?

Sunstreaker allowed himself a smile as the personnel hatch on the ship opened, revealing a number of broad mechs. Some he knew, some he did not. But they couldn't have mattered less. What he was concerned about were the femmes. They were mixed in with the mechs, but stayed together, as femmes were prone to doing.

Femmes were…wary of the twins. They weren't stupid. They could nearly feel the waves of menace coming off of Sunstreaker. With Sideswipe, it's a little different. He could hide his darker side behind broad smiles and soft kisses. There was nothing Sunstreaker could do to try to hide; he was better off being gorgeous and let the femmes know that while he was dangerous, he was also an amazing lover.

There was no doubt about that, he thought to himself as he squared his broad shoulders, smiling at the femmes. His smile only broadened as he noticed the femmes looking in his direction. He flexed his crossed arms, watching as they began whispering with each other. With femmes, it was all about making sure they knew that the twins were always available.

"Well?" Sideswipe asked as the door to their shared quarters whipped open and revealed Sunstreaker.

"They'll be knocking down our door." Sunny smiled at his brother, walking across the room and settling into his berth for the night.

Their room was cluttered with all knick-knacks and thing-a-ma-bobs that Sideswipe had collect on their various journeys throughout the various galaxies. Sunstreaker tolerated the junk because it made his brother smile when he recalled a memory associated with the item. If it were up to him, the only thing in the room would be paint and canvas.

A knock on the door had both Sunstreaker and Sideswipe sitting bolt upright, looking at each other with excitement. Swipe was the first one up and to the door, nearly slipping on an old tube of red touch-up paint that had fallen from its shelf.

Sunstreaker followed, but at a leisurely pace. There was no reason to make the femmes feel like he was excitable. Excitable mechs were expendable mechs, both in the femme arena and the gladiatorial arena.

Sideswipe pushed the glowing red button by the side of the door, which unlocked and opened the door with a light 'whooshing' noise. On the other side of the barrier was a little, pretty, delicate femme.

Carina had experienced what the humans would have called 'a hell of a day.' It had all started with a rocky landing, meaning that she was on the hook for repairs. Oh, the life of a mechanic. It was constant work on the ship, which was nice for her. She got a little…twitchy with nothing to do.

But, her luck hadn't stopped there. When she had gotten off the ship, well after everyone else had debarked, so she could examine her ship, she was told to report to Prowl's office. Well, Prowl was not in his office, but was in a meeting with Optimus Prime himself, so she had sat in the hallway outside the office for two earth hours. With nothing to do. Twitchy.

After Prowl had emerged, he had the gall to yell at her for 'eavesdropping' outside Optimus Prime's office. At which point she had snorted a very un-femme like snort and told Prowl that the walls surrounding the Prime's office were thicker than his helm. She had never seen a mech so angry that he couldn't process his vocalizations.

After being threatened with the brig and having a nice mech named Jazz come to her rescue, she was let off the hook and given a stack of data-pads that was taller than chassis to go through in the next several days.

Naturally, she had no idea where her quarters were, so she had to comm-link with Prowl to ask him (politely) where her quarters were. He told her the number and sector, but there were no numbers outside of doors. Luckily, there were sector names painted in standard Iaconian in the halls, letting her know that she was at least in the correct sector.

After dumping her datapads in the corner, she picked a door in the hallway and knocked. Of course, there was no answer. So, she quickly found herself on a downwards spiral. She was beyond tired and ready to recharge right there in the hallway. She sunk down the wall, right next to the stack of datapads. There was no way she was recharging in the hall. She had learned that lesson- after Warpath had stepped on her. Then asked her out.

She sighed, moving her head to the side in defeat. There was one more door. She stood tiredly, moving towards it. It looked for all the world like somebody had decorated the door. It was painted both red and gold. Somebody had to live here. It was far too odd for a storage door to be painted so beautifully.

She raised her hand and knocked, rocking back on her heels, waiting for a response.

The femme was small and green. Sunstreaker usually hated green, but this femme looked good in green. It was a dark, hunter green, not at all like the lime green like Ratchet had decided upon. Her blue optics clashed magnificently with her green paint job. She was about ¾ their size, but seemed bigger because of her build.

She had a very femme-esque build. She had a large bust, small waist and fuller hips. She looked nothing like the other femmes who had landed that day. She wasn't streamlined enough to be an administrative bot, but she wasn't big enough to be a warrior bot. She was somewhere in between.

Sunstreaker relayed this thought to his brother over the internal com-link. Sideswipe's response was so male and desperate he almost chuckled.

'I don't care if she is somewhere in between an administrative bot and a warrior bot. As long as she's in between us, it doesn't matter.'

'She looks tired. We should invite her in for some recharge.' Sideswipe turned to invite the femme in, but was surprised when the little femme opened her mouth and ruined his come-on.

"Where is room 216? I need to find it, please." Her blue optics looked up at them flatly, as though she knew what kind of conversation they were having in private.

The door slid open to reveal two of the most beautiful mechs she had ever seen. They were side by side, with the red one slightly in front and the gold one in back. The red one was non-threatening, with his hands down to his sides. It was the golden one who looked semi-threatening. His optics were piercingly blue and keyed in on her like she was prey.

'They look exactly the same,' she thought to herself, 'Just…different colors.' She cocked her head, looking at him with knowing optics. They were having an internal-conversation on their comm-links. How rude.

She waited patiently for the mechs to at least recognize her presence, but neither of them made any move to welcome her or invite her in. Rude.

"Where is room 216? I need to find it, please." Her tone was a tad short, but she was fed up with the rudeness of the mechs on this base. First Prowl, then these two.

The two of them took their focus off each other and focused solely on her. It was nearly overwhelming. But, she hadn't lasted this long among the warriors without having a spinal structure around such domineering personalities. She tilted her head back a fraction and crossed her arms in front of her body, waiting for a response.

Both of the mechs suddenly looked tense, but the mech in front- the red one- relaxed visibly. Then, he smiled. She was a little embarrassed to say, but her vents hitched when he smiled. He was so beautiful. The smile didn't quite reach his optics. It made him look even more handsome in a way- it made him seem like he had something going on behind his optics.

"Please come in, missy. I'm sure we will be able to pull up a map for you." The red one moved backwards, shoving paint and odds and ends out of his way, clearing a path for the femme and his golden friend.

The golden mech didn't move a cable. He stayed unmovable, faceplate unreadable. Carina moved around him, edging into the room, ducking slightly. She followed the red mech into the messy room, watching as he seated himself at a personal computer terminal in the back of the room.

"I apologize for the mess, missy. We're usually not this messy, but it's been hectic…we've had to move rooms lately." He grinned up at her before going back to his terminal, typing quickly.

"And who are 'we?'" She asked as she began to wander the room. Her femme creator had always told her how rude she looked when she let her curiosity rule, but it was a life-long habit. She always made herself at home, no matter where she was- or who she was with. It was a personality quirk that often times got the small femme in trouble.

"We, little femme, are Sunstreaker and Sideswipe." The golden one answered, from where he was leaned against one of the berths. He looked at her with a disdainful optic, noseplates turned into the air.

"Well...," She paused, looking between the brothers in an exaggerated manner, "That does explain a lot." She smirked at the golden twin, who merely watched her impassively, large arms crossed over his immense chest.

The two beds, the paint splattered everywhere, the bad attitudes, the rudeness. It all made perfect sense now. The two infamous twins. Kept in the Autobot army because they were two of the best fighters Optimus Prime could ever have. But, there was always a price to pay when it comes to keeping the best. They were known for being rude, reckless and downright violent.

"Room 216 is just down the hall. I'll take you to it," The red twin, Sideswipe, stood from the terminal and walked to her, "C'mon, little femme."

"Carina. My designation is Carina." She blinked up at him, noting how broad he was.

One of those massive arms reached around her shoulders and guided her from the room. Safely past the glowering golden mech who was guarding his berth. They exited the mech's quarters smoothly, with Carina, allowing Sideswipe to guide her. While she was a cold, cruel and calculating bitch from time to time, she knew the importance of friends. Especially friends in low places. And these mechs seemed to fit in the 'low places.'

The pair walked down the corridor swiftly, although Carina was somewhat unsure of the situation. Tales of the pair had begun to trickle into her processor. Stories that were macabre and ominous. Stories that had made her shiver and have feelings of gratitude that she was on their side, instead of against them.

The one that was with her, Sideswipe, was quite the lady's man. He was known as being the more tame of the two, and therefore the femmes were attracted to him. He was a taste of danger, but still tame enough to know when to stop. Sunstreaker on the other hand was a rat-bastard. She had heard enough stories to fill a volume of Alpha-Trion's works with his exploits.

He was the gladiator. He was the one who appeared to truly enjoy slaughtering his opponents. He would stand over the top of his fallen enemy with his sword held high, smiling like a mad man. After getting out of the rings and winning his fame and freedom, he had still participated in underground fight rings, making a ton of money.

One side of her wanted to name him a cold-sparked murderer and leave it at that. But, he couldn't be all bad. Some of his paintings were the most beautiful works of art that Cybertron had ever seen. Some of his sketches were so valuable that they had sold for hundreds of thousands of credits. Unfinished, rough sketches had sold for hundreds of thousands of credits. The mere thought had her processes spinning wildly.

It was said that for Sunstreaker to paint you was akin to the Prime naming you a Lord- it was one of the most distinguishing things a spark could do. Some of his paintings were hung in the Prime's offices, and some resided in the Iaconian library. What she wouldn't give to have one of his paintings, even if just for the sheer amount of credits she could sell it for.

"Um…femme?" Came Sideswipe's clear, strong timbre as he looked down at her. "We're here. Room 216."

"Oh! Sorry. I was lost in the abyss of my processor," She said bashfully as she realized that they had been standing in front of the door for about a half a breem.

Sideswipe chuckled, rubbing his large hand between her shoulder armor, "It's no big deal. We've all been known to trail off into our thoughts on occasion." He leaned down, crowding her with his chest plates in front of her and his large hand between her shoulders, "Were the thoughts of me? How about Sunstreaker?"

She laughed lightly, trying not to let on that he was entirely correct, even if was incorrect in thinking that the thoughts were inappropriate.

"Of course not. I was only thinking about how I was going to decorate my quarters. I was thinking red and gold. They seem like great colors, especially for a berth room. What do you think?" She giggled as his optics unfocused slightly, then refocused on her face.

"I think that I could personally rub some of my paint on your berth." The way he purred was definitely doing something for her, she could tell by the way her pump sped up and her optics threatened to unfocus.

"I think...no. No way." She giggled at the downtrodden look on the mech's face.

She turned, opening the door with her own pre-programmed code and stepped inside. At least this time Sideswipe stayed in the doorway. Maybe this one was not as rude as she had initially thought.

"Come in." She ordered him in with her back turned.

"Bossy femme," The femme was stunned to find that the voice was right behind her, more than three paces into the room. How had he moved that quickly? "I think that you need to check your tone with me and my twin. Surely you know the ramifications if you don't." His voice was so sexy. It was deep and smooth, but had a hard edge of male-dominance to it. She was silent for a few moments, just soaking in the sensation of his vents on the back of her neck.

"I don't want you to hurt yourself choking on those big words, sweetspark. I think that you need to stick to words that you can pronounce quickly and easily." His presence was overwhelming, he must have been as close as he could be without actually touching her.

Sweet, hot vented air reached her neck. She knew, in the back of her processor, that she should be scared of this mech. She really should be frightened. But, there was no way she was going to back down. She would never back down from a fight. It usually got her aft beaten, but there was no way she could afford a reputation as a mechanic who backed down from a fight.

"I like you."

"There you go! Use small, easy to say words! Good mech." After that jab, there was no way she could turn to face him. She would laugh in his face and while she was okay teasing the bull, there was no way she was going to wave her ire in his face.

Slowly, as if he was thinking it through as he moved, he pressed himself into her back. Wide red hands appeared on her stomach, tracing the ridges that rested there. A chin made itself at home on her helm. A small, feminine part of her processor, noted with pleasure that they fit together perfectly. Which meant that she and Sunstreaker would fit together perfectly as well.

"I can feel that you like me too, little Carina." He chuckled when she couldn't stop the tiny purr from escaping her vocals. "How long has it been for you, little Carina? For Sunny and I, it's been a while. We would more than welcome you to our berth."

While Carina would never go to a mech's berth the first night she met him, she was nothing if not a vicious tease.

"I'm not sure your berth would fit both of us, sweetspark." She chuckled as his hands ducked lower, only to be covered with her own. There was no way he was going to get a free feel. She had some amount of dignity left in her life and it would not be wasted on this randy mech.

"All three of us," He corrected with a heated vent to the back of her helm. "Both of our berths will push together and make a berth that is more than large enough for the both of us to partake in a lengthy and satisfying interface."

"There you go again. Stop trying to use big words. I'm starting to get worried that you're going to hurt yourself. Then where would we be?" She laughed softly when he nipped the back of her neck in warning.

A gush of feminine fluids told her that she was letting the teasing get out of hand. It was time to separate herself from this mech. She turned out of his grasp, with her hands still clutching his own. His optics were burning with the intensity of the Cybertronian moons. She almost- almost- felt guilty for letting the both of them get this worked up.

"Sideswipe. I will not interface with either you or your brother. Not tonight. And never with your brother. He looks like he ingested bad energon. I can't get off when somebody looks like that in the berth. Sorry." She had the good sense of processes to look contrite.

Sideswipe grimaced, shifting his stature uneasily. His hands came free of her own, which immediately rubbed his chest, right above his sparkcasing.

"Tease." His optics bore into her own, wanting her to deny it.

"Of course. What femme isn't?" She returned, squaring her shoulders, readying herself for a fight. Unlike Warpath, however, Sideswipe's faceplate broke out into an unexpected grin. It stretched across his entire handsome face and reached his optics.

In that instant, she almost regretted saying that there was no way she would interface with him. He looked so alluring, standing there in front of her. A mech she knew almost nothing about, standing in front of her, mech-handling her. And she liked it.

Sideswipe and Carina stared at each other for more than was necessary. Sideswipe was desperately hoping the femme would go back on her word and jump his gears. The femme was hoping the mech would simply leave, so she wouldn't have to deal with the awkwardness.

Sideswipe felt the pull of his brother's spark on his own. Sunny was wondering where he was, what was taking so long?

'You aren't screwing her, are you?'

'No.' He returned to his brother. 'I wouldn't do that to you.'

"Well, my femme, I must bid you good recharge. And I hope you find all your decorations in time, including the paint shades you need." With that, Sideswipe ducked out of the room, and headed straight down the hallway, to his own room.

Sunstreaker was still wide awake by the time Sideswipe stepped out their washrack. It was one of the perks of having a brother that 'bots were uncomfortable with. Separate everything. They even had their own energon and high-grade dispenser.

"So…" Sunny began, "Why are you giving me the warm-and-fuzzies if you didn't screw her?"

"I'm not all the way like you, you know. I don't have to screw a femme to like her."

"That's where you're wrong," Sunstreaker said with a smirk. "I don't even like them after I've screwed them."

Sideswipe snorted. He knew better. "So, that's why you cuddle up with them and won't allow them to go home until after they've recharged with you, right?"

Silence met his inquiry. There was no lying to the other half of your spark. Sunny knew that, but sometimes he needed reminding that there was no way Sideswipe was ever going to let him forget that he felt every emotion Sunny had.

"I just don't like her." Sunny stated, kicking back further into his berth, propping his head on his hands.

"Why not?" Sideswipe asked as he clambered into his own berth, flipping over so he could watch his twin.

"She's just…just…pushy. Mean. Stubborn. Rude. She gives me a weird vibe."

Sideswipe laughed. "She gives you…the wrong vibe? That's the funniest thing I've ever heard you say. Except that one time when you got stuck on the grate right outside the tournament grounds."

Sunstreaker looked at him sourly, the usually handsome mech's faceplate turned in disgust.

"I'm just telling you. I get an uneasy feeling about her." The golden mech stated, flipping over so his back was presented to his brother.

"I can tell you what I felt," Sideswipe said quietly, pensively. "I felt her body. It was the body of a young and beautiful femme. And I want a piece of that. So, if you please, be nice to her and maybe I'll share with you."

Sideswipe barely managed to duck the pillow that came flying at his face. He laughed loudly, knowing that his brother was perturbed by the thought of him 'doing' a femme without the golden brother. Anything that one did was immediately transmitted into the spark of the other. Therefore, having a hot and heavy interface session with any femme would be fed from one spark to the other. It would make things uncomfortable at the least, embarrassingly angry at the most.

Carina lay in her berth, thinking over her day. It had started out horribly, but ended…with her spark getting revved unexpectedly. She smiled into her berth covering. She could live with that. She might even encourage it in the future.

But for tomorrow, there was a stack of datapads in the corner that was threatening to have its own gravitational pull. That would be her focus for the next couple of days, or Prowl would have her head.

Well, there it is. It's the making of a beautiful something with the twins. I like writing Sideswipe, but Sunstreaker will come in heavier later in the fic. I hope you all like the feisty and snarky Carina. Carina is the name of a constellation somewhere, so it relates to transformers. Sort of. But, there you go. I like them all.

Sideswipe is very forward, but that's just in his personality. Sunstreaker is an asshole. And Carina is going to be caught in the middle of a mech smitten and a mech smote. It should be fun.

Please review. I can't know if you like it or hate it without a review. I live for them.
