Orion almost chuckled at Megatron's reaction, lips twitching in amused pleasure at his tested restraint. But his want was easily overruling his amusement, and Megatron's quaking thighs only made his anticipation all the greater. Casting the cloth aside, Orion slid his hand over the exposed paneling edges, eagerly set to explore.

"Oh, very good."

The heat and the charge was obvious, even without touching Megatron's exposed valve directly - but when he did, fingers gentle, the charge crackled quietly, and shot right into his system, leaving his arm tinging.

Humming in pleasure, Orion dropped his helm down between Megatron's splayed thighs, and pressed lips and tongue to the warm metal between valve and spike housing.
