Skyfire x Optimus

(I FINALLY GET TO INDULGE IN MY HEIGHT KINK WITH THEI PAIRING-)
Prompt/s: Height difference kink
Skyfire: Safewords exist for a reason. Optimus. I'm gonna prove that to you.
Skyfire is much bigger then Optimus and despite how badly Optimus wants to mate, he cant fully take Skyfire which annoys them both.
Optimus is a breeder, he has a very high desire to mate and somehow Skyfire is able to keep up with it.
————————————————————————————————-
Optimus was calm and collected outside of the berthroom, frame always held with an air of confidence. He walked through the halls quickly to get back to his office and to his mate before someone caught him and he had to do something else. He groaned softly when he entered his office, Skyfire was sitting at his desk with a concerned look on his face. "Your late, Optimus..whats wrong? Your never late." He said gently, standing up and walking over to Optimus' smaller frame. Optimus smiled softly, his optics flickering with desire as he looked up at Skyfire. "I was just...preparing myself," he said, his voice low and husky. "I want to...mate with you, Skyfire. I need it." Skyfire's optics widened slightly, surprise and arousal mixing in his gaze. He knew how much of a breeder Optimus was, but to hear him express it so openly was a turn-on. "I'm ready when you are, my love," he said, his voice deep and rumbling. Optimus nodded, his servos shaking slightly as he reached up to pull Skyfire down into a passionate kiss. Their frames pressed together, the height difference between them obvious as Skyfire towered over Optimus. But that didn't stop Optimus from trying to take control, his servos roaming over Skyfire's broad chest as he tried to push him towards the berth. Skyfire chuckled, his servos gripping Optimus' hips and lifting him up effortlessly. "You're eager tonight, my little breeder," he teased, kissing along Optimus' jawline. "But don't worry, I'll take care of you." Optimus moaned softly, his head tipping back as Skyfire carried him towards the berth. The height difference between them was even more apparent now, as Skyfire lowered Optimus down onto the soft surface. Optimus whined slightly, "..i've just been stressed and need to relax..." he mumbled softly Skyfire nodded understandingly, his large hand stroking down Optimus' back in a soothing gesture. "I know, my love," he said, his voice gentle. "But remember, safewords exist for a reason. If it becomes too much for you, if you need me to stop, just say the word." Optimus nodded, his optics shining with trust and love. "I know, Skyfire," he said, his voice soft but firm. "But I trust you. I know you won't push me too far." Skyfire smiled, his thumb rubbing circles into the small of Optimus' back. "Good," he said, leaning down to capture Optimus' derma in a deep kiss. "Now, let me take care of you." Optimus purred softly as one of Skyfire's large servos rubbed at his panel, he moaned quietly as the larger mech pressed and rubbed at the thin metal covering his interface. Skyfire's touch was electric, sending shivers down Optimus' spinal strut. He arched into the touch, his own servos gripping Skyfire's shoulders for support. Skyfire smirked, his optics dark with desire as he worked on opening Optimus up. He knew just how much his little breeder needed this, how badly he craved release. And he was more than happy to provide it. Soon enough, Optimus was writhing beneath him, moans and whimpers spilling from his vocalizer as Skyfire worked him over. The height difference between them only seemed to enhance the intensity of the moment, as Skyfire towered over Optimus and dominated him completely. Optimus had let his panel snap back awhile back and whimpered as Skyfire's large digits worked in his valve to get the muscle cables to relax, he panted and arched sharply when Skyfire hit a sensitive bundle of sensors and cried out. Skyfire's smirk grew as he continued to work his mate's valve, his own arousal growing with each moan and cry that escaped Optimus' derma. He knew just how to touch him, just how to make him feel pleasure beyond anything he had ever experienced before. And as the pleasure built within Optimus, he felt himself getting closer and closer to the edge. He could feel the heat coiling within him, the pressure building until he couldn't take it anymore. "Skyfire," he gasped, his optics wide with need. "I-I'm gonna-" Before he could finish his sentence, he was thrown over the edge into an explosive orgasm. His entire frame shook with pleasure as he cried out Skyfire's name, his valve pulsing around the larger mech's digits. Skyfire continued to work him through his climax, not stopping until Optimus was completely spent and panting for air. He withdrew his fingers slowly, giving Optimus time to come down from his high before moving to rub his inner thighs. Optimus shuddered and panted glancing up at Skyfire with dim optics, his mask was down again and the scar covering one half of his lower face was on display. Skyfire leaned down to press a gentle kiss to the scar, his servos soothingly stroking down Optimus' thighs. "You were amazing, my little breeder," he said, his voice filled with pride and love. "Simply amazing." Optimus smiled softly, his optics slowly brightening with affection. "Thank you, Skyfire," he said, his voice soft. "You always know just how to take care of me." Skyfire chuckled, his servos rubbing soothing circles into Optimus' thighs. "Of course, my love," he said, leaning down to kiss Optimus' forehead. "I will always take care of you."Skyfire smirked slightly and sat up tugging Optimus into his lap "how sensitive are you at the moment? Can you go another round?" He asked with a low purr. Optimus gasped softly as he was pulled into Skyfire's lap, his sensitive valve still pulsing with aftershocks from his previous orgasm. But the idea of going another round with his mate was too tempting to resist, and he found himself nodding eagerly. "I-I think I can handle it," he said, his voice slightly breathless. "I want you, Skyfire." Skyfire grinned, his optics darkening with desire. "Then you shall have me, my little breeder," he said, leaning in to capture Optimus' lips in a deep kiss. He let his own panel snap back and his massive spike extend, Optimus shuddered and whimpered wiggling slightly in the taller mechs lap. Skyfire chuckled at the reaction, his servos gripping Optimus' hips firmly to steady him. "Easy there, my love," he said, his voice low and husky. "I'll take it slow." He guided himself to Optimus' wet and slick valve, slowly pushing inside as he watched the smaller mech's expression for any signs of discomfort. But Optimus only moaned softly, his optics dimming with pleasure as he adjusted to the size of Skyfire's spike. Optimus growled softly and whimpered when, like every other time they had done this, Skyfire's spike couldn't fit fully. Despite how much he wanted it, he knew his frame couldn't handle the full size of Skyfire's spike. He panted softly, his optics pleading as he looked up at Skyfire. "I-I'm sorry," he said, his voice strained with desire and frustration. "I want it so badly, but I can't-" Skyfire cut him off with a deep kiss, his servos soothingly rubbing over Optimus' back. "Shh, my love," he said, his voice gentle. "It's okay. We'll find other ways to make you feel good." He began to move his hips slowly, his spike sliding in and out of Optimus' valve in a slow and steady rhythm. Optimus moaned softly, his own hips rocking to meet Skyfire's thrusts. He wrapped his arms around Skyfire's neck, holding on tight as he let himself get lost in the pleasure. He panted and moaned loudly when Skyfire started to get faster and rougher and he arched sharply when that same bundle of sensors was hit, he cried out loudly and clawed at Skyfire's back. Skyfire growled low in his vocalizer, the sound sending shivers down Optimus' spinal strut. He knew just how to touch his mate, just where to hit to make him feel pleasure beyond anything he had ever experienced before. And as the pleasure built within him once again, Optimus knew he was close to another explosive orgasm. "Skyfire," he gasped, his optics wide with need. "I-I'm gonna-" Skyfire cut him off with a deep kiss, his hips thrusting harder and faster as he worked to bring Optimus over the edge. And it didn't take long before Optimus was crying out, his entire frame shaking with pleasure as he came hard around Skyfire's spike. Skyfire continued to move within him, prolonging the pleasure until Optimus was completely spent and panting for air. He withdrew slowly, pulling Optimus into his arms as they both lay there, panting and dazed with pleasure. The height difference between them was forgotten as they held each other close, basking in the afterglow of their lovemaking. "I love you, Skyfire," Optimus said, his voice soft and filled with affection. Skyfire smiled, his servos soothingly stroking Optimus' finnials. And I love you, my little breeder," he said, his voice equally soft. "Always and forever."
