Requested by: @Cricketluver sorry this took so long😅

Setup: I just added detail to your request, I didn't really change anything, hope this is okay~Megatron sends Starscream and Y/D on a mission together. They are already lovers, though it's hard because of Starscream's random disappearances from the Nemesis when he's kicked off by Megatron. They decide that since they are alone, they should take this chance to interface. 

Warning: Lemon (so dis RoboSex) also a bit of anger/fighting between Screamer and reader but all's well that end's well amirite? 

Other Information: This my second lemon so bare with me also sorry for any typos

Seeing Stars

my POV (1st Person)

It was a normal day on the Nemesis, which meant for me that a certain mech I love is begging for Megatron's acceptance, as usual. 

"Lord Megatron, please, I live to serve!" The gray seeker kneels, voice dripping with dramatic effect. I resist the urge to roll my optics at his pathetic attempts, yet I feel worry building up inside of me. The five famed words are choked out of his grovelling voicebox. "Give me one last chance!" 

"Time and time again you fail me, Starscream. You have shown your true intentions. You ask for one last chance, but you've run out of those." The heat was building up, and I could no longer stand and watch. This time, I felt my sweetspark wasn't going to be so lucky. 

"Lord Megatron, please, wait." I kneel in front of the warlord, trying my best to be strong and respectful, though inwardly you were shaking. "Please, my liege, give him another chance to prove himself. I can take him with me on my quest for the relic and report his actions to you. If he tries anything, I will prevent it. I am your best soldier, after all."  

There is a heavy silence that engulfs the Nemesis, at least where I am at. For a long moment, no one moved or said a word. Finally, the leader of the Decepticons steps closer to you, his pedes steps loud and sharp in my audio receptors. Nervousness stirs in my tank and my vents are short and shallow. "Y/D," You straighten up, and cautiously look at Megatron. "Your request is granted to you, but if you come back empty-handed, Starscream will not be the only one becoming one with the Allspark." 

"Yes, Lord Megatron," I bow again, and make ready to leave as Soundwave prepares a ground bridge. The gray Seeker quickly dismisses himself, and before you can dart out, Megatron stops you. "Y/D, while it is true you are a formidable warrior and your skills are second only to mine, I also know of my strong bond to Starscream. Don't misplace your loyalty." A shiver runs through my body and I give a shaky nod before leaving. 

☆☆☆

"Something wrong, my dear? You've barely spoken to me." Starscream frowns, glancing over at me. 

"I'm working," I say, ignoring his pleading optics. 

"I can see that, but you don't seem very. . . Happy." The gray Seeker treads carefully, but he's playing with fire. 

"Happy!?" I lash out at him, and he steps back quickly. "How can I be happy when my sweetspark is never around!?" 

"Oh, it's about that," he mumbles under his breath. 

"Yes, it's about that. How come you're never around? How come you get yourself into trouble I have to get you out of? How come you only care about your stupid, fragging self!?" I yell, red optics ablaze with anger as you thrust a digit into his face. 

"I-Iー" 

"You think that's all? Oh Starscream that's only the beginning!" I step closer to him, and he puts his servos up defensively. 

"Y/D wait! Please. . . Give me one last chance!"

Those words trigger something deep inside me, and just as I was about to explode with rage, I transform and fly off into the sky. 

"Y/D WAIT!" I hear from behind me. "PLEASE! I'M SORRY!" I ignore him until I hear, "PLEASE. . . I-I LOVE YOU, MORE THAN ANYTHING ELSE!" I halt as I near the ground, transforming as I land. 

"Please Y/D. . ." Starscream vents heavily as he lands, touching my shoulder gently. Flinching slightly, I sigh and turn around with tears in my optics, catching him by surprise. The soft mech pulls me in for a hug, and I weakly bury my helm in his chassis. "There there Y/D. . ." He whispers softly to me, stroking my helm. After a few moments, I step back, take a deep breath, and slap him across the faceplates. 

"IーWhaーI thought we made up!" 

"Technically, you didn't finish your apology." 

Starscream sighs. "Well. . ." He begins. "I would first like to compliment your natural beauty, Iー" This earns him a whack, and if looks could offline, his spark would surely be snuffed. I didn't want flattery, I wanted some apologies. "I'm sorry for being selfish and not thinking about you. . . You mean the most to me but I have not shown that. . . Allow me to show you how much you mean to me. . ." He mumbles softly, and that slightly deeper, more serious voice melts my spark as he hugs me. "Starry. . ." I nuzzle into his shoulder blade. "You fragging idiot, I love you."

"I love you too Y/D. . . Does this mean. . ?" 

"Yes." I nod, looking up at him. In a blur of a moment, his dermas meet mine, and he kisses me sweetly, tenderly. Closing my optics, I feel him bite my dermas. I reject him, and I know what he'll try next, so I beat him to it, squeezing his aft. He gasps and my glossa shoots inside his mouth. He struggles to dominate me, but loses. I grin into our passionate kiss, and our makeout session progresses quickly as he runs his digits down my back. I arch my back, our bodies touching until there was no space left between us. Our glossas entwine as I moan softly into the kiss, and hear him moan as well. I slide a servo down to his interface panel and he suddenly breaks the kiss, pulling back as he arches an optic ridge.

"Just what do you think you're doing, sweetspark~" he hums with a smirk, pushing you back gently into a small cave for more privacy. "Something you. .  . Want?~"

I swallow as I feel myself dripping under my own panel and nod, gasping as he suddenly uncovers my breasts and toys with them with those long digits. I moan and whimper a little before gathering myself and pushing him back against the wall. 

"You won't win against me that easy Starry~"

He gulps as your servo snakes down to his bulging interface panel, and I tear it off to reveal his erected spike. It wasn't huge but I am kind of relieved as I know this will hurt a little anyway. 

I move my own interface panel off as I feel my fluids drip down my legs. Starscream's optics widen as he takes in my bare body, vents catching. Before I knew it, he had pinned me to the ground and aligned his spike with my entrance. "Are you ready, Y/D?" he asks softly, to which I nod vigorously. He slowly sheathes himself in me and I whimper and moan, tears slipping out as he allows me to adjust. "Are you alright my sweetspark?" I nod, and once I'm adjusted he begins thrusting deep and slow, being gentle with me.

I moan out for him and claw my digits down his back, gripping his ultra sensitive wings, causing him to jolt up in me and increase his pace as be thrusts in deeper and faster and rougher. "S-S-Starscream~" I moan out loudly and he hisses slightly as he goes faster and faster as I grip his wing. I get an idea to make him go faster and boost his ego. "L-Lord Starscream please~" I cry out for him and his optics light up as he slams into me harder and harder. I hear our moans mix as his spike repeatedly slides in and out, crying out each other's designations. 

I feel a knot forming in me, and I gasp, hearing him moan into my audio receptor and urging me to cum. "S-Starry~" I moan as my fluids spill, and a moment later I feel him slam in, his spike bursting inside of me. His body collapses on mine and we pant after the intense round. 

"I-I love you. . . Y/D. . ." Starscream looks me in the optics with an exhasuted but adorable problem. I smirk and he looks a little concerned for himself with my smugness as I grin and push him back but keep his spike in me, pinning him to the ground. 

"Who said we're done here?" 

Starscream laughs nervously with a small whimpery moan. "Uh. . . No one. . ." I smirk and start moving up and down on him harshly, valve clenching around his erected spike. He moans and grips my hips, helping me as his eyes graze my Y/C (your color) frame before watching my valve go up and down on his spike which is now slicked with my fluids. He moans and cries out my designation as I continue going up and down as fast and rough as I can. "P-please my queen, f-faster~~ h-harder~~" I growl and do as he requests before slamming down as he cums and me shortly after. 

Moments pass as we calm down, clearing the stars from our vision. We kiss deeply and passionately before slowly recuperating and clean up before walking out and looking over the sky which is slowly being speckled with stars. Starscream and I hug closely as we gaze at them, dreaming together. "I love you Y/D. . ."

I look at the star which will always shine the brightest in my universe. 

"I love you too Starscream."

-Timeskip-

Megatron hisses as he looks over us both, but seeing as we had successfully acquired the relic and I had convinced him of Starscream's help and that he should be again a part of the Deceptions, he had no choice but to let us go without punishment. 

 ~Bonus~

Soundwave plays back the sounds coming from Starscream's berth. 

"A-Ah!! L-Lord Starscream, h-harder!!!~~" 

"Mm, you're so tight my queen~~" 

Megatron's face is contorted in horror and he swallows awkwardly. 

"I appreciate your concern Soundwave, but I believe those words will stay in Starscream's berth and are not a threat elsewhere."
