The woods fell silent as Sunstreaker drove over the small dirt road. Between the budding trees, birds and small furry animals darted for cover long before he passed. Not because of the speed, but because of the male right behind him on his tailpipe. (Y/n) had offered immediately to join him before Sideswipe could offer, to Sunstreaker's annoyance. He had tried to sneak away without getting the male's attention, but unfortunately, (y/n) kept a close optic on him. 'Someone has to make sure you don't die...' (y/n) had said before departure. Cocky bastard. Sunstreaker could perfectly handle himself and if he wanted someone to join, then it would be Sideswipe and no other mech or femme.

They reached the main road. (Y/n) tried to bait him into distraction, rambling about a nearby village he'd wanted to visit. All Sunstreaker wanted to do was head home, wash all the dirt from his armor and enjoy his younger twins' company. 'It won't take long. We can make a quick stop, come on!' The powerful engine of (Y/n)'s alt-mode rumbled with impatience. 'No! Go alone. I want to go back.' Sunstreaker let out a yelp as (Y/n)'s bumper hit his. 'You idiot! Watch my paintjob!'

(Y/n) let out a low laugh. It send shivers down Sunstreaker's spine. 'We are going. Unless you want to tell Prime you abandoned me. You were clear you wanted to take lead in today's scouting missions so take damn responsibility.' Sunstreaker considered in how much trouble he would be for killing the mech right here and now. Stupid brat. (Y/n) had come from a higher society, grew up in a loving home and never had to worry about finding Energon the next day. He never experienced pain like Sunstreaker had or his brother. 'We are going,' (Y/n) stated again and took a turn. Sunstreaker had no other choice but to follow him or risk Prowl's wrath if he returned without (Y/n).

'Fine, but hurry, you stupid prick.' His holoform activated seconds later and slumped back in his leather seat. Sunstreaker doubted he would be back before dusk anyway. He parked at the side of the road and waited for whatever thing (Y/n) wanted to do.

He watched people walk by and gape at his alt-mode. They surely don't see a sports car like his any day. Some took pictures, others simply spoke excitedly. Sunstreaker maybe would've enjoyed it if it wasn't for the arrogant bastard dragging him into this Primus-damned town for whoever boring reason. The mech tapped impatiently on his steering wheel and watched the minutes pass. 'What the fuck is he doing?' Sunstreaker scolded under his breath, checking his mirrors again to see if he could spot his companion.

Only ten minutes later, the passenger side door opened and Sunstreaker watched (Y/n)'s holoform hop in. 'Eat.' The order. Sunstreaker bristled and snitched the sandwich from his hands. 'Don't tell me what to do,' he snapped. 'I can hear your stomach even from miles away.' Sunstreaker rolled his eyes and took a bite. He caught the male stare at him. 'What? You came all the way here to give me human food?' he shook his head. 'You know... accepting help or kindness is not a bad thing. You're Energon levels are low and you can use some extra food.'

'I don't need you.'

'You always care about your brother but no one ever cares about you.' Sunstreaker took a second to take it in. True, people don't like being around him. They assumed he didn't need anyone either. 'So?' Sunstreaker took another bite. 'I care for you.' Sunstreaker almost choked in his bite and turned his head. (Y/n)'s face was tight, unreadable. 'I don't want your pity, or your help.' He rolled his (e/c) eyes. 'Sure you don't. So, you wouldn't like to have someone care for you?' His hand rested on his knee and Sunstreaker stared at it for a while. His icy blue eyes met (Y/n)'s (e/c) ones.

'No!'

He pushed his hand away. 'I don't want to be touched like that, especially not by males.' (Y/n) hummed softly, surveying every detail of his face. 'Is that why you're trying to be dom?' Sunstreaker didn't reply. 'Or do you really want to play tough mech?'
'My valve is off limits. I don't let mechs spike me, not after—' he cut himself off. 'Your father,' (Y/n) finished quietly and stared out of the windshield. 'I'm sorry you had to go through all of that.' Sunstreaker blinked and stared at the male beside him. The male that had been trying to dominate him since he arrived on Earth. 'I uh... I know how it feels.' Sunstreaker blinked a couple of times. 'But you grew up in a rich family, with parents who loved you to death. You weren't thrown on the streets like garbage...'

'My family was slaughtered by the Decepticons when the war just reached Kaon. The only reason I'm alive is because I wasn't home that day. I joined the army shortly after, but got captured by the dreads... you know what they are known for.' Sunstreaker's throat tightened. 'How long?' Sunstreaker watched the male closely, counting the seconds anxiously before he replied. 'I was their plaything for three years.' Sunstreaker's throat bobbed. 'I'm sorry.' The male shrugged and took a bite of his own sandwich. 'You're right, I did pity you, but the moment I saw you, I was instantly sold. I admired your strength and spirit but, I noticed that people don't seem to care the same way you care for others.'

'I don't care for anyone but my brother. I've sworn a vow to Prime and it's only pure work related. I don't owe people anything nor do they owe me something.' (Y/n) slumped back. 'But they don't give you credit for your work. Do you think they will mourn you?' Sunstreaker's chest tightened. 'What exactly are you trying to reach with this, (Y/n)?' A muscle ticked in his jaw. 'I would.'
The yellow twin rolled his eyes and finished eating. 'Can we go back to the base now? I want to see my twin.' He stared for a very long time, too long. 'Does it frighten you?' Sunstreaker cocked a brow. 'If you're with a mech, I mean.' Sunstreaker knew what he meant and debated answering fairly. He had given a part of himself, it would only be fair to give a part of himself too.

'Why do you think I don't invite mechs to sleep with me?'

(Y/n) hummed softly. 'So, no male had ever touched you after what happened.' Sunstreaker nodded. 'Exactly, now hop out. I want to go back.' (Y/n) nodded and hopped out of his alt-mode.

Sunstreaker arrived at the base way past midnight. Exhausted from the trip he fell asleep in the hanger. The next morning, he was awoken by a soft caress over his hood. He transformed and backed off, bumping right into the wall and fell down on his aft. 'What the hell do you think you're doing! Get away from me.' (Y/n) snorted in amusement. Sunstreaker rose to his feet. 'Fuck off.'
Sunstreaker marched through the hangar to the shower stalls.

He took off his armor to get the dirt out and scowled under his breath. He couldn't quite reach all places to his annoyance and was just about to order Sideswipe to come down here and do it for him as two large servo's rested on his shoulders. 'Get away from me!' (Y/n) ignored the Sunstreaker and started scrubbing down his back. 'I don't need your help!' He swirled gracefully. 'You were about to call for Sideswipe anyway.' Sunstreaker bared his fangs. 'I rather ask Sideswipe then an arrogant alphahole like you!'

(Y/n) snorted in amusement and kept continuing his actions. 'Get your servo's off me!' (Y/n) raised his servo's at peace. 'Can't you just let me be helpful?' Sunstreaker growled. 'Leave me alone.'
(Y/n) optics trailed down Sunstreaker protoform. War surely put him in shape. His optics trailed lower to his codpiece. A low dangerous snarl escaped Sunstreaker's throat. The kind of snarl that had people running for their life's but (Y/n) didn't move an inch.

'You might be older, but that doesn't give you the right invade my privacy, stupid piece of trash metal.' Sunstreaker jabbed a finger in the center of his chassis. (Y/n) was only a few inches taller and smirked. 'Did anyone ever tell you that you have a dirty mouth, Sunstreaker?'

The front liner bristled and watched the (f/c) mech take off his armor and drop it on the ground. Sunstreaker turned away and continued washing himself until he felt company behind him. Those large servo's gently trailed his spine again all the way to his hips. 'So delicate... did anyone ever tell you how beautiful you are without armor, Sunstreaker?' Sunstreaker's faceplates flushed and he was frozen in place.

'I know I am handsome,' he groused eventually. (Y/n) servo's trailed all the way back up before gently removing the dirt and mud between his cables and overlapping plates. Sunstreaker braced his servo's on the wall. The touch electrified his entire body. So gentle and exploring. He hadn't felt this way to anyone before. His traitorous body produced a low purr as the male behind him removed dirt between the cabling of his neck.

'You know... I believe you like being submissive.' Sunstreaker opened his mouth to sneer at the male but those Primus-damn servo's worked their magic on his body and had him locked into place. 'I see you, I care about you...' he whispered near his audio. Sunstreaker's spike pressed painfully hard against his codpiece and (y/n) doubt could smell the change in emotions as well.

The male behind circled idly with his digit over his back. Slow, taunting circles. The same digits that minuted ago explored every scar and curve of his body. (Y/n) at last pulled back. Sunstreaker slowly turned, his cheek plates still heated. 'Wash me.' A raw command, not a question. Sunstreaker's shaking servo reached for a nearby cloth and started scrubbing down the male's chassis. His body just as powerful and muscular build as his own.

Sunstreaker didn't take orders from anyone except Prime or Prowl, but he couldn't disobey (Y/n). He never could.

After washing, he fled to the safety of his brother and had told him everything. Sideswipe followed the ridge of his cup with his fingers, listening without interrupting. At last, he lifted the cup to take a sip of his coffee. 'Right...' Sunstreaker watched Sideswipe consider. 'You would never tell me this type of thing because you always tell yourself you can handle it yourself. Do you want me to... do something about it or...?' He trailed off. 'I don't know, okay? It makes me nervous.' Sideswipe flashed him a warm, loving smile. 'Not all mechs have bad intentions, Sunny. (Y/n) probably does care. Perhaps an arrogant bastard but he never tried to hurt you.'

'True...'

Sunstreaker changed his seat to sit right next to Sideswipe. Their shoulders touching. It was smoothing. 'I'm sorry I didn't came back sooner. (Y/n) wanted to make a stop at the village and I was too tired when I came back.' Sideswipe snorted. 'It's fine. I get it and I was in recharge too. If something was wrong you would've tugged on our bond.' Sunstreaker nodded slowly and stared out of the window. Sideswipe nudged him with his elbow. 'Relax, he won't hurt you. He won't take advantage of you the way others did.' Sunstreaker flinched at the words, but nodded.

'I'll rip out their interface circuits if he does,' he added. Sunstreaker appreciated the words and smiled.

Sunstreaker headed off to the gym to get out some nerves and frustration. Half way down his work-outs, his attention went to the door as it opened. (Y/n) strode in. Sunstreaker turned away, lifting the weights with ease. Why now? He came here for some peace. 'Sunstreaker,' the male greeted with an erotic purr that wasn't lost on Sunstreaker. He dropped the weights and swirled with feline grave. 'What do you want from me, (Y/n)?' He snapped. The mech halted, cocking a brow. 'What do you want from me?'

'To leave me the fuck alone.' (Y/n) barked out a low laugh. 'You wanted more from me this morning.' Sunstreaker bared his teeth. (Y/n) approached and eyed him carefully. Before Sunstreaker could snap at him again, the mech kissed him. Sunstreaker went rigid. (Y/n) tightly grabbed his hair, sweeping his tongue over his teeth and tongue. Every inch was explored before he pulled back,— salvia dripping down both their chins. Sunstreaker face was pale, near ashen as he stared at (Y/n). Such a passionated kiss. He couldn't remember when he was kissed like that.

'If you need help showering again, give a shout.' (Y/n) winked and walked off. Sunstreaker bristled. 'Stupid, arrogant prick!' He sneered,— turning on his heels and left without finishing his work-outs.
