“Fight it, go get a mated pair now and close the door.” Jace hears the words but doesn’t understand, too preoccupied with running the backs of Alec’s hands over his skin. He wants Alec’s fingers to grip his waist and wrists, leave marks all over him. Jace can’t get close enough.
Out of nowhere, someone is grabbing Jace around the waist and dragging him away from Alec, “no! No, Alec!”
“It’s for the best Jace, I promise.” It’s Robert. Robert is taking him away from Alec.
“No, no, I need him, bring me back to Alec. Where is he?” Jace can’t see him, partially due to the tears blocking the way.
“Hey, I’m right here” Alec is there, hands cupping Jace’s face and wiping the tears away, “I’m here. It’s ok.”

I’m very picky when it comes to A/B/O fics, but this version, where Alpha Alec manages to resist the unexpectedly Omega-presenting Jace? Yes please!
