While there was no more than token initial resistance to his hand being pulled away, Cliffjumper squirmed under the gaze and sputtered, shaking his helm. His horns were alight with charge and a tingling sense of pressure, the sensor nodes there heightened enough in sensitivity the touches lingered, building charge even when Optimus drew his hand away. Beautiful? All sparks looked the same, right? So why call it that, and he totally was not.

"Shut up. The slag I am." Huffing and looking away from the Prime as looking at him looking at his spark just... made him feel strange, Cliffjumper nonetheless curled his hand into the light grip Optimus had on it.

To give himself something else to concentrate on rather than Optimus staring at him (in a way hard to describe or replicate when the spark was neatly tucked away and hidden), Cliffjumper shifted the hand he still had on Optimus shoulder to curl about his helm instead, thumb slowly brushing over the base of the audial fins.

He still couldn't bring himself to actually look at Optimus, or worse, look down and see that hand so very close to his spark.
