Orion was apparently intent on driving him spare with this meticulous slowness. Even now that he'd actually gotten inside. A groan thrumming through him, Megatron arched into the slow, twitching progress and attempted to simply draw him in by twisting his hips and tightening his valve.

Orion managed to keep his own pace, however, which simply left a building storm of charge skittering along the workings of his valve and between his valve and Orion's spike, leaving him hissing.

"I have no idea what you're - nnh - talking about, Orion. I'm pretty sure---ngh!" The smug, probably insufferable smirk disappeared into a soft-mouthed, open moan as charge flared up, everything clutching. Megatron's whole frame jerked when Orion closed his teeth against his throat, and he somehow managed to arch up further, helm tilted back to bare his throat.
