Cover art for Velvet lyrics by Breathe Carolina

I think the song is about them "doing it". They're getting more and more into it, losing control ("watch he inhibitions fall to the floor) as his "lust" as BellaXsaur said, is building and she strips her velvet dress, most likely. The "word" may likely be sex, because they don't want admit what's happening.

My Opinion
