This one gave me a hard time, so it took a bit to get it up. Sorry about the wait, and thank you to all ho have read and reviewed and followed and favorited! You guys rock.

Rated M for trinesmut of the sticky variety. Yum.

Still isn't mine, unfortunately. :(

-7- Dominant "You were mine even then; you just had to take the time to realize it."

"I do not submit." Thundercracker said finally, heaviness in his tone. "It is simply not something that I enjoy."

"TC, I'm your trineleader." Starscream said, and Thundercracker could see the youth within him, the idealism that hadn't yet been stripped away by time and troubles. The troubles were there, though- he himself still wore the mental scars from his ordeal in Tarn, and then /this/...this was too much. He wanted this, though. Wanted it with everything that he was. He wanted to /belong/.

"And what is /that/ supposed to mean?" the elder Seeker said finally, looking over the frame in front of him with an anticipatory dread that Starscream frowned to see.

"It means that you will submit to me." Star said, grinning. "You're acting like you never have."

Thundercracker froze. That really /was/ the crux of the matter, wasn't it? He /hadn't/, not willingly. And not even all the way. The last time a lover had...had /tried/, he'd freaked out. It hadn't felt good, it had felt damned uncomfortable and painful.

Starscream stared at his new trinemate. "You're kidding me."

"No." TC said simply, looking at his pedes.

::Thundercracker, I won't hurt you.:: Starscream said through the trine link.

::It always hurts.:: he said, not looking at the smaller red and white flier. ::I /don't like it/. I never have. And I doubt I ever will.::

Starscream sat heavily on the berth, and it was obvious that he was thinking very hard. "Let me. Let me try. If you...if you don't enjoy it, I'll stop."

TC had heard /that/ before. The difference here was that he actually cared about what Starscream thought of him, that he...might be willing. He sat next to Starscream and stroked a white wing, a wing that arched into his touch. "I...Scree...all right." he finally said, resigned.

He was his trineleader. And Thundercracker cared. He thought wryly for a moment that at the very least Skywarp wasn't here to see this; Warp's comments, however well-meant or whatever went through the teleporter's pretty purple head, weren't needed right now.

"Are you sure?" The grating tone in Starscream's vocalizer was absent, and crimson optics looked nearly through the blue Seeker.

"...Yes." And Thundercracker took Starscream into his embrace and kissed him.

Star was always the eager one; he leaned into the kiss and even shoved his trinemate down onto the berth, hands on his shoulders, pinning him lightly to that same berth as his lips explored TC's own with a heat that was entirely characteristic of the flier. That was okay; it was /more/ than okay when Starscream's hands grasped Thundercracker's upper wing edges firmly, two fingertips massaging the outer sensors.

"You're mine, you know." Star purred against TC's lips, and that brought surprising warmth to his frame. "Mine then, mine /now/, and mine /forever/." Starscream's lips attached themselves to Thundercracker's neck cabling, and the elder Seeker moaned softly; that too felt good, and he could feel his tension dissipating slowly. He tried not to think about what would come soon, and just fell into the moment.

Starscream sat up, straddling Thundercracker, and looked down with desire and want. "Relax." he ordered, and TC offlined his optics, trying to do just that. Maybe it would be easier if he didn't see what was happening.

He felt a soft touch on the side of his helm and then he /couldn't/ see anymore; Starscream had attached an optical inhibitor, and he could feel warm air brushing across his cheek. "I said relax."

"Don't-" TC said, the loss of his sight the exact opposite from comforting, and his frame stiffened. Starscream immediately removed the inhibitor. "I didn't mean to.."

"You did not know." Thundercracker said gently, and he laid himself back down, his frame still stiff but not overly tense.

Starscream smiled slowly. "I think I have an idea, something that might help." The lithe flier began kissing slowly down Thundercracker's neck, and TC couldn't help but shiver at that; even with Star's weight atop him, that just felt good. Cobalt hands brushed lightly across the seal of his glass, and he rumbled out a quiet sound that could have been a moan. Starscream felt encouraged by that, and continued down, his lips moving in a slow slide until he nipped gently at Thundercracker's pelvic armor. "Open to me." he said, and that twinge of worry came back, even as TC opened himself, baring his valve to his trineleader.

"No, all of you." The laugh in Starscream's voice was clear, and Thundercracker's breath caught. Was Star just going to do things the usual way? Star's lips closed around his spike housing and Thundercracker was finding it difficult to think at all.

Starscream loved the feel of Thundercracker between his lips, even if the Seeker's spike was not precisely small and he had to work at it to take it all in. The /sounds/ he made as Star gently ran his glossa over the ridges and sensors, the gasp when he sucked sharply...all of that drove him, and when his fingertips danced lightly over Thundercracker's valve rim TC barely noticed at all. His hips pushed up into Starscream's intake and still he didn't stop, his own low sounds sending vibrations up the considerable length as he swallowed him deep.

"Starscream-" Thundercracker gasped, his hands reaching for the wideswept white wings that shuddered at the sound of his own name. Star drew off slowly and gave TC a smirk. "Hands at your sides." Those were familiar words to Thundercracker; he'd said them often enough while 'facing Starscream, and he groaned, complying reluctantly. He couldn't even push Star down onto his spike; he was helpless under the onslaught, and the feeling of that was a little...Stimulating, for once.

Starscream slowed down with his lips, barely laving the tip with his glossa...and his fingers continued to slowly, so slowly explore the outer sensors of Thundercracker's valve, which was actually beginning to slick up under the gentle treatment. He circled the entrance with just one fingertip, the lubricant that barely had begun to form easing his way, and he slid that same fingertip just barely inside the larger Seeker to massage the lower rim of his entrance. Starscream sucked sharply at the head of TC's spike as he did this, and the Seeker cried out at the dual stimulation, his wings pressing hard against the berth. That had actually felt good!

Starscream was encouraged by this and slid the finger in just a bit more, curling it against the sensitive walls, and Thundercracker gasped aloud; he could /feel/ himself getting wet beneath his trineleader's touches, and it felt odd and good and a bit frightening all at once. He wondered when it was going to start hurting; it always did.

A warm, wet glossa laved his spike, though, and each ridge and sensor was thoughtfully attended to by Starscream's talented lips, so distracting that Thundercracker didn't even notice when Starscream slid in a second finger, rocking his hand ever so slowly inside his trinemate. The movement felt.../good/. TC was surprised, and he moaned softly, the deep tone different from the sounds he'd been making at the attention to his spike."Star..." he whispered, his hips actually arching lightly into the cobalt hand. "Don't stop, Starscream."

The red and white Seeker purred loudly and swallowed Thundercracker's spike almost to the hilt in one smooth movement, his intake clenching around it like a valve in the throes of overload. The blue flier moaned loudly, the deep rumble rolling throughout the room, and Starscream slid in a third finger, moving harder and faster through the new slickness. He could feel the walls twitch around his fingers, and he could feel TC's spike throbbing between his lips- he was close, and Starscream knew then what to do.

He rose up, sucking hard, and just as TC's spike left his mouth with an audible 'pop' he grasped it with his free hand, stroking firmly. His other hand slid out from the lightly clenching port to trace Thundercracker's lips, making him taste his own lubricant just as TC did to Starscream on occasion.

The elder Seeker moaned at his own taste, riding up into Starscream's hand. "/Slaggit/, Star-" he moaned, almost ready to flip his trineleader and /take/ what he wanted. Starscream smiled down, a genuine smile, and covered TC's lips with his own, sliding between parted thighs and into his trinemate for the very first time ever. Thundercracker tensed- this was when it was going to hurt, the intrusion would be too painful to bear...and he offlined his optics so that Starscream wouldn't see the pain reflected in them.

They flew open almost immediately, right along with the sharp gasp that escaped him against his will when Starscream swiveled his hips and hit someplace Thundercracker didn't even know he had, causing a wave of intense pleasure to crash over him from nowhere. Large hands took Starscream's hips and pulled him closer, and the smaller flier gave Thundercracker a look filled with satisfaction as he began to move more firmly, twisting at the end of every thrust just to hear Thundercracker cry out at the stimulation. His legs parted further, wanting Starscream to go deeper, not knowing how to handle this except by shivering under him. Starscream leaned down to nip at TC's audial. "You like this." he said, and it wasn't a question.

"What do /you/ think?" Thundercracker hissed, one leg riding high on slender hips.

"I think you /do/." Starscream whispered and thrust inward harder, wringing a sharp cry from his trinemate. He did it again, and again and again until Thundercracker writhed and arched beneath Starscream, his valve drawing him in as far as he could get. The vibrations on his plating shot through Starscream himself and he slammed in as hard as he could, dragging Thundercracker with him in an intense overload that left them both wrecked and panting to cool their frames. Star collapsed on top of TC, his face pressed against cool glass.

"It didn't hurt." Thundercracker murmured. "I even enjoyed it."

"You trust your trine not to harm you." Starscream said softly, reaching to pet a wing edge. "You don't have to do this again, not if you don't want to."

Thundercracker held Starscream close to him, feeling a strange ache in his interface array that had nothing to do with pain or fear. "And if I do want it?"

Starscream just grinned.
