If only he had his voice. The sudden, surprised keening wail would have surely been impressive. As it was, his arch was sharp, jaw jutting against the gag in a silent scream as unexpected warmth and charge shot through his spike, seeping into every petal-thin gap and joint and seam.
The chuckle only made it worse, vibrations echoing right through thin plating and circuits and going straight to his core.
Optimus had been expecting anything but his own pleasure once Megatron had persuaded his planel open. His optics are wide enough that his surprise is probably quite evident, and what little remains of his control is hanging by a thread.
