"What's the matter, can't keep up anymore?"

"You started before I did! That's cheating!"

"Primus you're such a baby! C'mon try to catch me!"

With a playful revv of his engine Sunstreaker sped off away from Sideswipe, his rear mounted engine roaring and his tires squealing on the desert roads. Their patrol had been quite uneventful up to that point so now the twins were racing -and bickering- as if it was one of their days off. After revving his own engine in the same playful manner, Sideswipe caught up with his brother, and softly bumped the nose of his alt mode in his brother's rear bumper.

"Nice aft!" He chuckled when he heard his brother's indignant yell. The golden Lamborghini had been just about to scream something about his paint getting scratched when he heard his brother's words, and he instead purred through their comm-link, his voice betraying the smirk that would be tugging at his lip-plates if he had been in his robot mode. "Of course it is, it's the best one you'll ever see. Glad to see you like it."

"Primus Sunshine, you're insufferable!" Sideswipe laughed, moving to drive side by side with his twin. Sunstreaker laughed too, revving his powerful engine. The yellow warrior was in a fairly good mood... no matter how unbelievable that was. His patrol shift with Sideswipe had made him forget the previous encounter with Tracks and the rest of the mechs in the Rec Room. Sideswipe had always had both the ability to frag him off completely, and make him forget about everything wrong in life, bringing out that elusive smile of his. Yup, he couldn't imagine what his life would be without his brother, no matter how irritating he could be from time to time. "I'm not insufferable!" He tried to sound offended, but his laugh completely ruined the effect. After a few more miles both twins pulled over to sit under a couple of trees that were on the side of the road, not caring that they should be patrolling the area instead of fooling around. The Decepticons had been laying low lately, so they decided to take a little break. What Prowl didn't know, didn't harm him, right?

Sideswipe sat on the ground first, looking up at his brother as he scrutinized the ground. Sunstreaker's face was contorted in a frown as he looked down at the dirty floor, glaring at the dust that was surely gonna get his armor dirty. The red front-liner grinned, and even though he knew Sunstreaker wouldn't be pleased with him, he grabbed his hand and pulled him down to his lap, the golden mech landing gracelessly on his legs with a loud clanking sound.

"You idiot, if you scratch my paint I'll kick your aft!" He growled as he straddled his brother's hip-plates, one leg on each side of him as he slid his arms around the red mech's neck. Sideswipe's grin never faltered, his optics bright with amusement and now, given their current position, barely hidden desire. Wrapping his arms around his golden twin's waist he pulled him closer, capturing his lip-plates in a soft, tender kiss. Just like all the previous times Sunstreaker lost himself in it, the gentleness of their kiss slowly driving him insane. After a moment Sideswipe pulled away, pressing his fore-helm against his brother's, their gazes locked together as he let out a long sigh.

"Sunny, are you sure you want to do this?" He said after a few silent minutes. He knew what his brother had told him a couple hours ago, but he still couldn't believe his brother, his perfect and beautiful brother would want to be with him. Not only because they were twins, but because Sunstreaker could have anyone he wanted. Track's words were still swirling in his processor but he didn't mention it, knowing his twin would probably not like it at all.

"Do what, Sideswipe?" The golden mech asked warily, his optics slighlty narrowing as he glared at his twin.

"You know what I mean. This. Us." He said almost painfully, never breaking optic contact even though he wanted to.

Sunstreaker sighed irritably, softly thumping his helm against his brother's. "Are you dense or just stupid? I already told you back in the base what I wanted. You know I don't like saying things more than once." He growled, his glare defiantly locked in his brother's gaze. "I like this. I want this. I want /you/. What else do you need to know, dumbaft?" He hissed, but leaned closer to kiss his brother again. Sunstreaker would have loved to tell his twin exactly why he wanted it, why he wanted to be with him but... he didn't know how to. Words had never been his strong point. Neither were emotions.

"I don't need to know anything else now." He smiled, returning the kiss and letting his hands caress his brother's back-plates. Grinning mischievously he slid his fingers into one of the back seams, finding a node that he knew was particularly sensitive and without breaking the kiss he pinched it, choosing that exact moment to deepen their already heated kiss, sliding his glossa into his twin's mouth. Sunstreaker's back arched as he let out a loud moan, the pain and pleasure torturously running through his lines and setting his circuits ablaze. Deciding to be a tad bolder he pushed his golden twin until his back was pressed against the ground and he climbed on top of him, expecting some sort of reproach about the dirty ground. When he got none he leaned down to kiss his brother again, his hands travelling through the expanse of Sunstreaker's body as the latter writhed and moaned under him, his back arching everytime his brother found and pinched an overly sensitized node.

"Sideswipe!" Sunstreaker cried out his brother's name when he felt the red mech's dental-plates closing over one of the lines in his neck, softly and teasingly biting his way down to his golden chest-plates. Sunstreaker was in heaven, the pain and pleasure from his brother's ministrations were revving him entirely too far and he moaned again, his hands moving up to caress Sideswipe's side-seams. However, as his hands finally brushed against his twin's plate he found his wrists being strongly captured and securely pinned above his head . "Tsk, tsk... No Sunshine, I'm the one touching now. You're gonna have to wait for your turn." Sideswipe grinned, shifting so only one of his hands was holding his brother's wrists and the other went back to the amazing task of mapping his brother's body. He knew Sunstreaker liked this. He knew his brother was a fierce warrior and just as tough as everyone thought he was... and he wasn't meant for being nice. He'd give him exactly what he knew his brother needed.

He cut his brother's retort with a heated kiss and moving his hand up to caress his brother's helm-fins, before he moved his helm to whisper in his twin's audio receptor. "I'm gonna take you right now, Sunshine." He purred, teasingly running his glossa down the golden ridges in the fin. Sunstreaker moaned at his brother's words, his cooling fans kicking in to try and cool his rapidly heating frame. Hearing Sideswipe like that was too slagging hot for him. "I'm gonna make you scream my name over and over again..." The red mech softly bit the black rim of his twin's helm-fin before he finally continued, "I'm going to fuck you and you're gonna overload for me..." His voice trailed off as he slid his free hand down his twin's body until it was finally teasing his brother's panel, smirking when the soft click of the retracting metal reached his audio-receptor. Leaning down for a crushing kiss, he reached down with his hand to caress his brother's now exposed valve, sliding his fingers over the lubricant coated metal before slowly, teasingly sinking one of his fingers inside of his brother's writhing body.

Sunstreaker gasped, arching his hips in invitation, his valve clenching around his twin's finger that was now stroking him and caressing nodes that had never before been touched. A soft moan escaped his lip-plates as Sideswipe dug another finger inside of him, hot pleasure running thickly through his lines. He wanted his hands to be free, he wanted to caress his brother back, to touch all those sensors that would make his twin gasp and moan for him, but he was securely pinned, and Sideswipe didn't look anywhere near letting him go.

"Like this?" Sideswipe purred at him after he broke the kiss, grinning predatorily. He tightened his grip around his brother's wrists and after pulling his fingers out of his twin's valve he positioned himself between his long and golden legs, letting his own panel slide aside to reveal his own interface array and allowing his spike to expand outwards. The tip of his spike brushed against his twin's valve, ripping a moan out of both twin's vocalizer.

Without waiting another second Sideswipe thrusted hard into Sunstreaker, causing his perfect yellow brother to cry out in pleasure. Letting out a soft moan himself he paused for a second, allowing his brother's body to adjust before he set a slamming pace, thrusting into his brother relentlessly. "Sides..." Sunstreaker groaned his brother's name, unable to say anything else as his brother's lips closed over his own in a searing kiss, the feeling of his Sideswipe's spike sliding inside and out of him sending pleasurable jolts of torment through his heated and overly sensitized frame.

Sideswipe thrust harder every time, the feeling of his brother's slick valve clenching around his spike was driving him insane with pleasure and he leaned closer to kiss his brother one more time as his free hand caressed his helm-fins again, stroking the black rim with his thumb. Sunstreaker whimpered softly under him, arching his back and angling his hips upwards to get even more of his brother. That new angle allowed Sideswipe's spike to go even deeper, stroking all those nodes that were slowly pushing his brother over the edge as he moaned and groaned his brother's name. Sideswipe kept his pace, moaning as he stared at his brother's writhing form under him. Sunstreaker looked absolutely beautiful laid out beneath him, his whole frame trembling as his brother pounded into him, pleasure only increasing his already growing charge and setting his circuits ablaze.

Sunstreaker would have never imagined doing this with his brother. To have his twin's spike filling him and thrusting hardly into him, pushing him towards a steadily growing overload was something he never before thought about. Now, however, it was all that mattered to him. He spread his legs wide, wanting more of Sideswipe, more of his twin, more of his spike inside of him, pounding relentlessly into him. Sideswipe had never thought about that either, even though he had always known about his brother's stunning beauty. The memory of his golden brother taking him the night before, and the feeling of his brother's slick valve surrounding him was burning him alive, barely able to focus on anything else as he dove into his twin with abandon, the feeling of completeness that was crawling up to his spark made him whimper, sealing his brother's lip-plates with his own in a scorching kiss.

Sunstreaker's overload was the most intense pleasure he had ever felt in his life, liquid fire pouring through his lines and burning through him as he screamed his brother's name, just as Sideswipe had told him he would. Sideswipe thrusted harder, faster and deeper into him as he overloaded, the feeling of his twin's valve quivering around his spike along with the sounds his golden brother was making pushed him over the edge as well, release finally reaching him as he remained buried deep within his twin's body, finally letting go of his wrists and allowing him to move. Sunstreaker's arms instantly wrapped around Sideswipe's waist, keeping him right where he was between his legs, panting and still whimpering as he felt his brother's overload pouring into him.

They remained intertwined and locked together for a few minutes, both twins panting after the powerful overloads they had reached. Sideswipe lifted a hand to caress his brother's face-plates, still buried to the hilt within his Sunstreaker's body. Sunstreaker's lips curled upwards in a tiny smile as he looked up at his twin's beautiful face, exhaustion evident in both their gazes. "Sides... " He was at a loss, completely unsure about what to say. He wanted to tell him how great it had all felt, how much he cared about him, how glad he was for having done what they had done the night before that had led them to this but.. he didn't know how to. Instead he settled for tightening his grip around his twin's waist, pulling him closer and pressing a soft, lingering kiss to his brother's lip-plates, one his twin eagerly returned.

"Sunny, that was... perfect. /You/ are perfect" Sideswipe all but whispered as his spike receded back into it's housing, the grinding sensation sending shivers down both their frames. Sunstreaker's smile grew larger at that, a soft chuckle escaping his vocalizer. "I know I am. And just like I said... you know I only choose the best for me..."

Sideswipe hesitated for a moment, considering his next words. He wasn't sure if he should say it, he didn't know how his brother would react to it but... they had been together all their lifes, and Sideswipe knew it was what he felt so, after pressing another soft kiss to his brother's lip-plates he smiled, pressing their fore-helms together. "Sunny... I love you."

Sunstreaker stiffened, the meaning of those words hitting full-force on his spark and he felt it lurching in it's chamber, felt as if it was about to jump off his chassis. Sunstreaker smiled, lifting one hand to caress his brother's cheek-plate as the other remained securely wrapped around his twin's waist, and after a moment's thought he replied in that same confused but oh so confident tone. "I love you too Sideswipe." The red mech's smile turned into a full grin at hearing those words, lifting both hands to cup his brother's face and pulling his brother in for a crushing kiss.

They were both confused, unsure of what to make of this whole new brand of emotions creeping their way into their sparks but... no matter how tough things would ever get, they knew they would always have each other, just like they always had. Now, however, they had finally realised that there was something more than that, that they meant more to one another than what they had originally thought. Not that any of them really stopped to think that. No, they surely weren't thinking about anything now that Sideswipe was sitting between his twin's long, strong legs, his glossa lapping at his brother's exposed and still quivering valve just as Sunstreaker's helm thunked back against the ground, groaning with the extremely pleasurable sensations. Sideswipe was trying to kill him, he mused, as Sideswipe's glossa slipped into his entrance just before he sucked on his valve itself. He then was completely unable to think of anything else other than his brother's talented glossa lapping at his valve and setting his circuits on fire once again.
