You took a deep breath as you moved your other hand up to his chest,
fingers lightly brushing against his exposed wires. You watched his face for
a reaction before moving again, still hesitant. Mettaton closed his eyes,
smile still spread across his face. You brushed your hand farther down his
exposed body, dragging your fingers against every loose wire on the way
down, careful not to tug on any too tightly.
Stopping at the container that held his heart, you removed your hand in
order to caress it gently, hearing him whimper slightly at the sensation. You
always loved how sensitive it was and sometimes you just couldn't help
yourself, not that he seemed to really mind. He loved showing off, after all.
