Heart of a Prime by LuvMiddleEarth reviews
Saphira was just a normal girl who bought a new car after receiving high grades at school. Turns out, that car was not what it seems and a whole adventure awaited her. Even if a giant robot with blue eyes might have caught her eye in a way she did not think was possible. Even he feels the same. Rating for violence, language, sexual themes and sex scenes. Optimus Prime x OC.

Shifting Gears by M. R. Prime reviews
She didn't ask for military secrets, and she certainly didn't ask for feelings for a giant robot who just so happens to be the leader of an elite alien race. All she'd wanted was a civilian contract that was going to secure her family's future. She didn't expect the job to actually become her future, but honestly - she wasn't complaining. [Optimus/OC]
