Feedback makes friends.  Flames dealt with by the masters of paranoia and fire, Red Alert and Inferno.

As a triple-changer, Springer was used to being larger than most of his friends.  It was something he never let bother him too much.  There were advantages and disadvantages to being his size.  Sometimes the advantages outweighed the disadvantages.  Other times of course, the disadvantages outweighed the advantages.

Interfacing was one of the disadvantages.

He had no particular preferences, like some others he knew.  He was quite happy to spike or be spiked.  The downside was satisfaction.  Sure, he could satisfy others (rather well judging by the repeat interfacings he got).  However, with his larger size, few could fill him completely.  Well, Ultra Magnus could, but there was no way he was approaching his commander for that.  Kup would probably have a few good ideas, but again, he really didn’t want to go there.

He hadn’t realised how much he was missing out until Trailbreaker came back to Cybertron.

 ~*~*~*~*~*~*~ 

Trailbreaker stepped off the ramp from Omega Supreme and looked around.  This time visiting Cybertron was certainly different from the last time.  This time, he wouldn’t be sneaking around to find components.  This time, he could actually relax a little.

“Welcome home.” Ultra Magnus greeted him warmly as Trailbreaker approached.  Trailbreaker smiled and shook Magnus’ hand.
“Glad to be back.”
“There’s only a few mechs stationed here.” Ultra Magnus explained.  “Kup, you know.  There’s also Springer, Arcee and Hot Rod.” Trailbreaker nodded as Ultra Magnus listed the mechs under his command.
“Sounds like a good little group.”
“It’s an… interesting group.” Ultra Magnus admitted with a smile.

 ~*~*~*~*~*~*~ 

It wasn’t like sparks flew when they were introduced.  In fact, they hardly did more than nod at one another and continue working.  It was after their shifts that they got together and spoke more than a few words.

Those words however, turned out to be quite intriguing as they talked about more and more personal issues.

 ~*~*~*~*~*~*~ 

“Oh frag that’s good.” Springer ground against Trailbreaker, trying to get closer to the black mech.  Not that he could actually get any closer of course; their frames were flush against one another, metal squeaking and squealing as they moved, but neither paid that much attention.
“Never figured you for a valve mech.” Trailbreaker murmured, nuzzling against Springer’s audio.
“Never… never actually get much chance for that.” Springer gasped out, hands sliding across Trailbreaker’s plating, unerringly heading towards his interface panel.
“Ah… they can’t satisfy you, can they?” Trailbreaker nodded understandingly, something that shook Springer more than he thought it would.  “It’s hard being bigger; there’s fewer of us to take our pleasure from.” He pulled back and kissed Springer once more.

“We can give so much pleasure, but who gives it to us?” He asked rhetorically.  “No one.  The mechs that are our size are usually unobtainable.  I wouldn’t dream of ‘facing Prime.  And I doubt you’d want to consider ‘facing Ultra Magnus.” Springer shuddered, not entirely sure whether it was from thinking about ‘facing his commander or from the dark, rich voice murmuring dirty words in his audio.
“But I’m certainly considering ‘facing you.” Trailbreaker all but purred, and Springer hated himself for letting out a small needy moan.
“Oh, you’d like that, wouldn’t you?” Trailbreaker continued, smiling at Springer’s moan.  From what he’d found out about the triple-changer, he could only imagine how much that moan had dented his pride.

What was it about Trailbreaker that made Springer just acquiesce to practically everything the black mech suggested?  Was it because he was older?  Technically older at any rate.  Was it because he considered Trailbreaker to have more experience?  Was it because Trailbreaker was part of Optimus Prime’s crew and he automatically garnered Springer’s respect?  Whatever it was, as Trailbreaker let his interface panel slide back, Springer decided he didn’t care.  He just wanted the mech to spike him.  And spike him good.

As soon as his interface panel had retracted, Trailbreaker guided Springer’s head down towards his spike.  The mech was eager, that much was for sure, but Trailbreaker didn’t want to force him to do anything he didn’t want to.  Though, judging by the way Springer moved willingly and nipped at the tip of Trailbreaker’s emerging spike, he certainly wasn’t averse to this.

Trailbreaker groaned as Springer’s talented mouth went to work on his spike, glossa laving up the length before he enclosed the tip in his mouth.
“Oh you’re good.” He praised the green mech, letting one hand rest on Springer’s helm.  Springer moaned something in return, pausing in his enthusiastic treatment of Trailbreaker’s spike.  He shifted and over the sound of their cooling fans, Trailbreaker could hear his interface panel sliding open.  He accessed his field generator and smiled.

Springer groaned, pulling back off Trailbreaker’s spike to glare up at him.  His hand hovered over his interface panel, unable to touch.
“You can’t touch this.  Only I can.” Trailbreaker purred, tugging Springer back to his feet.  Springer made a strange strangled noise, but moved when Trailbreaker led him over to the berth.
“Lie down.” Springer lay down and made himself comfortable.  He didn’t dare speak, lest he ruin what was happening.  He was a little confused at Trailbreaker’s actions, but the smile on the other mech’s face told him that he wouldn’t regret going along with things.
“Only I can touch this.” Trailbreaker repeated once he’d settled himself on the berth over Springer.  He brought his hand down through the forcefield he’d erected around Springer’s interface panel and dipped a finger into his spike housing, barely brushing the tip.  Springer made another strangled sound and bucked his hips up to meet Trailbreaker’s hand.

The sensation of his spike extending into the forcefield was like nothing Springer had ever experienced.  It felt… like nothing.  There was no air movement, no temperature change, nothing.  In fact, if his sensors hadn’t told him his spike was fully extended, he might not have believed it.  Trailbreaker moved his hand as Springer’s spike emerged, wrapping his hand around the length and squeezing just enough to be felt.  The moan from Springer told him exactly what the triple-changer thought of it.

“Enjoying yourself?”
“Nnnnn…” Springer’s answer was more of a moan than anything coherent.  Of course, that could have been because Trailbreaker slid his hand up and down the length of his spike as he asked the question.
“Oh, I’m going to give you so much.” Trailbreaker murmured.  “Make you see what you’re missing.  Though, you know what you’re missing, don’t you?”
“I know you’re a fragging tease.” Springer grumbled.
“Are you complaining?” Trailbreaker removed his hand, prompting a hastily muffled whine from Springer.
“Not at all.  Though I will be if you don’t get your hand back there.”
“Pushy aren’t we?” Trailbreaker grinned.  “You’re not really in any position to be pushy.”
“No.” Springer seemed to weigh up the odds.  “Please?” He was rewarded by Trailbreaker’s hand returning to encircle his spike, languidly gliding up and down its length.

It was strange, lying there and not feeling anything but Trailbreaker’s hand on his spike.  Yet it concentrated the sensations, drawing all his attention to what Trailbreaker was doing.  So much so that he was hard-pressed to remember to reciprocate.  Not that Trailbreaker seemed to mind of course.  Every time he moved to try and touch Trailbreaker, he was told to just lie back and enjoy himself.

So that’s what he did.  By the time Trailbreaker moved from his spike to his valve, Springer was writhing at every touch.  The first touch to the rim of his dripping valve had him arching and grabbing the berth in a desperate attempt to not overload immediately.  Trailbreaker seemed to sense this and slowed his movements, giving Springer the time he needed to calm himself down a little.  Nodding his thanks, Springer shifted to regain Trailbreaker’s attentions, reaching out to the black mech.  Trailbreaker moved, straddling him easily and leaning down to capture his lips in a heated kiss.
“Do you want me to give you what you want?” He murmured against Springer’s lips.
“Please…” Springer almost begged, canting his hips upwards hopefully.

And Trailbreaker obliged.  He moved back, sinking his spike in Springer’s valve in one smooth motion.  Springer was almost undone.  His valve stretched in ways he’d forgotten and all he could register was the feeling of being completely filled.  Perfect.  Trailbreaker didn’t move immediately, savoring the tight warmth himself.  But then he did, and Springer felt his resolve shatter.  He begged Trailbreaker to move faster, to move harder.  He gripped at the black mech’s shoulders, fingers digging in plating as he overloaded with a sharp cry.

Trailbreaker didn’t last much longer, as Springer’s valve seemed to milk his overload from him; clamping rhythmically around his spike until the charge was too much to bear and he overloaded.  He barely managed to hold himself up over Springer, before remembering that Springer was the same size, and then he allowed himself to collapse.  Springer made no comment, arms shifting to wrap around Trailbreaker.

There was something undeniably nice about being with another the same size as you.  There was no need to worry about heavier mass having an impact on your lover’s systems.  There was no real need to hold back due to the size difference.

Something that they discovered over and over again while Trailbreaker was stationed on Cybertron.
