The two guys are sitting together and the uke is staring at the semes hands.(I think he had a big thing for his hands, but i don't really remember) The seme notices him staring at them and swings his hand over, causing the uke to follow it. He then thought something along the lines of "just like a cat"

I know it's kind of vague, but thats the only thing i remember clearly.

Electric Hands?
