“Are you certain you won’t come with me,” Rung asked, gesturing to the extra space in his suitcase. “It would only be for a few cycles.”  He’d been asked to present at a conference in Tetrahex and, despite his offers, Megatron had declined to accompany him.

“Not this time, Bright One. I’m still needed here,” Megatron apologized, giving the smaller mech a lopsided smile.

“It’s a medical conference,” Rung tried again, hoping to encourage his conjunx. “You’d be my guest so no one should question you. Besides, with all that you’ve done since we’ve returned, I could–”

Megatron lifted his servo, halting Rung’s words. “I’m afraid I cannot, my love. There isn't enough staff at the clinic to operate it if I go and, with scores of Cybertronians returning every day, I want to be available should they need medical attention. There aren’t that many medics around and, what few there are, are spread thin.” That was only partly the truth; despite proving himself “rehabilitated” in the eyes of his tribunal, there were times he still received biting words and angry stares from mechs on the streets. It wasn’t that they weren’t deserved - he’d hurt an innumerable number of people - but he wasn’t eager to be in an enclosed space with other medical professionals who might look at him the same way. Rung didn’t need to see the hatred he still faced.

Rung gave a defeated sigh and closed the suitcase, scooting it to the edge of their berth. “Alright.” With a frown, he turned to face Megatron, anxiety fluttering at the edge of his field. “This will be the first time since you were trapped in the Functionist Universe that we’ve been apart.” Megatron watched Rung’s optics shift left to right as he searched for some kind of compromise before offering, “I could always postpone or see if I’d be allowed to do some kind of video conference.” 

Megatron moved in closer then, bringing a large servo to cup Rung’s face and smooth his thumb over his conjunx’s cheek. “No, Rung. You deserve to go, to see your research finally recognized. I would not be able to forgive myself if you missed out on this opportunity because of me.” His optics glinted mischievously as he leaned in, curling his frame imposingly over Rung’s. “However… I’d be happy to help give you a reason not to forget me.”

Rung’s engine gave a throaty growl with the implication. Despite knowing Megatron’s intention, he decided to play coy. “And… just how would you do that, gentlespark?”

In response, Megatron leaned in to catch Rung’s mouth in a claiming kiss, igniting the fire of need in his belly. Thin arms reached up and around Megatron’s shoulders to pull him in close - as if there were any other place Megatron would rather be. Stooping, he lifted Rung easily and carried him around to the side of the berth to deposit him down onto the soft cushions. 

“Open your array for me, Bright One,” he asked, his tone somewhere between a command and a request as he sank to a knee between Rung’s thighs. 

“Oh,” Rung gasped, his frame obeying before he could consciously send the command. Lubricant was already beginning to leak from between his folds at the promise of what was to come, but Megatron didn’t have the spark to tease him. After all, it would be a few cycles at least until he’d be able to enjoy his conjunx again.

With a deliberate slowness, Megatron leaned in to bring his lips to each of Rung’s brightly blinking bio-lights, earning a desperate whine from the little mech. “Patience, my love. I promise you will not be left wanting.” As Rung gave a small nod, Megatron continued. He traced the arc of each fold with the tip of his glossa, pointedly ignoring his conjunx’s anterior node - for now. Rung’s thighs trembled as he kept them spread apart and, sensing the growing difficulty, Megatron lifted his servos to guide them up and over his shoulders. Only then did he finally make contact with Rung’s node.

Rung keened loudly into the quiet of their berthroom, pleasure racing through his sensornet as Megatron sucked on his anterior node before pulling back to flick at it with the tip of his glossa. If that weren’t enough, he felt the thickness of a digit circle his entrance, gathering his slick before easing inside. “Megatron,” he whined, trying to cant his hips to encourage his conjunx to move faster. But then Megatron pulled back.

“I do not intend to rush through this, Bright One. You of all people should know that I am a very thorough mech.” Only once he’d received Rung’s a strangled noise of understanding did Megatron continue. Slipping a second digit into Rung, he scissored them to stretch his lover further, rubbing against several internal node clusters in the process.

Rung’s plating crackled with pent up charge, the excitement of watching his conjunx devour him palpable in his field. Bracing himself against the berth so he could keep his view, he watched as Megatron leaned in to once more assault his anterior node with skilled flicks of his glossa before slipping a third digit inside. With a shout, Rung felt the coil inside him snap and he overloaded, valve fluttering desperately around his conjunx’s fingers.

Megatron hummed appreciatively as he pulled back, bringing the thumb of his free servo to wipe the mess Rung had left from his face. “Beautiful. Absolutely beautiful.” After licking the gathered slick from his thumb, he withdrew his digits and cleaned those too, smirking at the steam wafting from Rung’s vents.

“And… how do you… wish to have me,” he panted, knowing that Megatron was nowhere near done.

“Completely,” Megatron answered, lowering Rung’s legs before he stood and climbed onto the berth. He settled against the head of the berth in a slightly reclined position and sent the command to retract his modesty panel, allowing his spike to pressurize with a loud hiss.

Rung’s frame gave a delicious shudder at the sound and he rolled over, crawling across the berth to where Megatron had positioned himself. With his conjunx’s assistance, he slung one of his legs over Megatron’s hips to straddle him, bracing against the larger mech’s chest with his delicate servos. “Completely,” he asked breathily, “How do you intend to do that?”

Megatron’s answer was simple. “Open your spark to me.”

Rung felt his valve ripple once more at the suggestion, realizing why his lover had chosen this position. “I would not deny you anything, gentlespark.” With several soft clicks, the glass of Rung’s spark window slowly slid aside, filling the room with brilliant blue-white light. Megatron’s expression went soft, and Rung found that he loved him all the more for it. 

“Exquisite,” Megatron murmured, lowering his servos to Rung’s hips to hold him in place while he rutted between his folds. “I could live forever and still not understand how I got to be lucky enough to take you as my conjunx.”

Rung beamed down at him, angling his hips to let Megatron’s head press against his entrance. Knowing it would be necessary if Megatron were to fit entirely, he opened his forge before leaning in closer. “Because I love you. Because I saw the efforts you made to change. To be better, do better. And all because you approached me first.” He leaned in then, slanting his mouth against Megatron’s and rocking back.

Megatron moaned into the kiss as he breached Rung, his servos guiding Rung into a slow, shallow rocking, slipping deeper inside each time until, with a soft pop , he was fully seated inside his lover. Rung trembled with unreleased charge, face flushed from the effort of not immediately overloading.

“Is something the matter,” Megatron asked huskily.

“I don’t… I don’t want it to be over yet,” Rung gasped, spark fluttering wildly in its open chamber. 

“Don’t worry about that. I plan on taking my time with you.” He shifted a servo then, gliding up Rung’s back to support the little mech and leaned in to brush his lips against the outer wisps of his conjunx’s spark. “Overload for me,” he murmured, snaking his glossa out to taste Rung’s spark.

Rung had no choice but to obey once he felt Megatron’s glossa make contact with his spark. Arching against Megatron’s servo, Rung shouted his release, only to feel Megatron begin to move within him. It was impossible not to feel each ridge of his lover’s spike catch against now-swollen nodes, building charge rapidly within him once more. And, perhaps most tantalizing of all, Megatron continued to kiss and lick at his spark, only breaking to whisper quiet affirmations of love that, while Rung couldn’t hear, his spark felt and understood. Eventually, Rung broke a third time over Megatron, spark flashing bright within his chassis.

Megatron canted his hips in earnest then, chasing his pleasure through Rung until, with the soft groan of his conjunx’s name, he buried himself deep within Rung’s forge and spilled. Rung felt the heat of Megatron’s overload spread through his belly and sent the command to close his spark chamber, sinking in happy exhaustion onto Megatron’s chest.

“How am I supposed to leave you after that,” Rung teased sleepily. 

“You could always leave tomorrow,” Megatron murmured, turning his helm to plant a row of kisses across Rung’s brow. 

“You know… I think I will,” Rung replied, draping his arms around Megatron before he fell into recharge. After all, he was right where he wanted to be.
