Starscream has always been one for physical affection, it's almost as though he can't keep his servos off of you. But, he's never once kissed you.

At first you thought that he simply didn't like kissing, but it had quickly occurred to you that maybe he just didn't know what kissing even is.

Which, to be fair, you don't think Cybertronians have ever needed to kiss.

"So, you're telling me that you humans... Smash your intakes together and make your glossa fight as a... Show of affection?" He looks understandably sceptical, but humans admittedly tend to do weird things with their tongues. "That sounds gross. Humans have... Liquid in them, don't you? Why would you share your intake lubricant?"

You're not sure either, but tradition dictates that kissing is always so romantic and perfect.

"Primus, you're such a weird little freak, aren't you?" Starscream asks, raising an optical ridge as he picks you up in one servo and lifts you closer to his faceplate. "But, I suppose if it will make you happy..." there's a small pause as he wrinkles his olfactory sensor before awkwardly leaning in and stopping just before he touches you, pouting his derma expectantly and keeping his crimson optics wide open.

Your own eyes close as you close the distance, lightly pressing your lips to his bottom lip, or derma as he calls his lips. They're cool, but not as cold as you'd expect solid metal to be. You pull away after a moment, looking up at him expectantly.

"Romantic! Are you kidding! That was even more awkward than when I accidentally walked in on Megatron watching videos of Optimus Prime!" Starscream turns his helm away, blue Energon rushing to his faceplate as he refuses to look you in the eye for a moment.

"Let me try," he suddenly says, pouting his derma again and pressing them against you. This time his optics are offline, copying you.

Due to your size difference, he winds up kissing the entire top half of your body all at once before pulling away, raising an optical ridge. "Is that it?"
