The cold metal of the wall pressed against your back, but the heat of Sentinel Prime in front of you was overwhelming.

His mouth was still close to yours, his blue irises intense, the gears grinding softly with tension. You had kissed. Long. Fierce. Wrong.

You were still Optimus's.

But Sentinel's lips still burned on yours.

So that's what's been hiding behind that look of yours?

His voice is deep, scratchy, almost an electronic whisper that vibrates in the air between you.

Do you think he knows you? That he sees you the way I do?

He comes closer once more, his strong metallic hands against the wall beside you, surrounding you completely. You try to look away — he won't let you.

I've wanted you since the first cycle I saw you. And now that I've had you... even if only for a second...

His voice trails off. He forces himself to continue.

...I won't pretend anymore. Or lie to myself. You're his, but he kisses me like you're mine.

The silence hangs heavy between you.

And if this is just a mistake... then why haven't you left yet?
