As the cybertronian sun rose over their newly forged union, Optimus's spark couldn't be more at peace. It felt like, for centuries, this was where he was meant to be, reciting his vows servo in servo with his now-conjunx, basking in the light of the sunrise and the palpable warmth in Ratchet's gaze.
The speech he'd prepared for vorns escaped his glossa now, and as he cleared his voicebox, he felt something heavier embrace his spark, warm and shining and whole, born of his affections and existing solely for his love.
He squeezes Ratchet's servos where they lay in his own, and smiles softly.
"My love, everything i am, everything i have ever been, since the day of my creation, is yours. This beating spark of mine, the warmth in my lines and my servos, every moment of happiness and memory, belongs solely to you."
Coolant gathers in Ratchet's optics, not borne of anguish, but of the sheer warmth that spreads through his chestplate at Optimus's words. He blinks the tears away, resisting the urge to bury his face in Optimus's chassis.
"Oh, sweetspark..."
Optimus continues, squeezing Ratchet's servos again gently, holding them firm in his own, wrapping his digits around them, gaze reverent as it meets his love's.
"You are my oldest friend, my dearest spark, the mech i choose to spend the rest of my waking cycles with, now and forever, until i join with the AllSpark."
Coolant is flowing freely down Ratchet's cheekplates now, an uncharacteristic little hitch in his voice as he nods and responds with. "I do too."
Optimus leans forward with a smile that almost makes Ratchet's spark do full-on somersaults in his chestplate, and when their derma finally connect it feels like bliss. The universe and all it's light, wrapped up in a tender kiss, and Ratchet feels as if he's ascending. Grateful and honored to be chosen by Primus to live up until this moment, the culmination of all their dreams and musings.
Ratchet whispers against Optimus's derma, arms around his neck cabling, pulling him closer as he confesses his vows in turn, voice shaking with emotion.
"Sweetspark, you are the one thing that i desire. To have and to hold, to be by your side always. To heal you has been my privilege, and through it all, i have never regretted a single moment spent by your side. I love you, Optimus. I adore you and i always will."
It's Optimus's turn to be emotional now, coolant gathering in his optics as well as he gazed at Ratchet like he'd hung every star, drew the constellations with his own servos. He presses their helms together with reverence, kissing Ratchet again, soft as a feather.
His conjunx. Finally his. Forever.
