[Verse 1] Beneath the door, I hear you move Bare feet in the concrete room Your name lands soft on my tongue Like a match that won't go out I wear the dark like second skin You pull me closer, let me in Every look says stay tonight Every touch says take my pulse [Pre-Chorus] Step by step, we sink Deeper than the night Step by step, we lean Into the underground [Chorus] Pulse of the underground Hold me, hold me down Pulse of the underground I want your heat in my mouth Pulse of the underground Don't let this love slow down Pulse of the underground We burn, we burn, we don't come out [Verse 2] Glass on the table, shaking slight Smoke on our clothes from the bassline drive Your hands trace circles on my back Like you know the map of me The room goes black, but I can see That fierce small spark in you and me We don't need words to cross that line We just move and we collide [Pre-Chorus] Step by step, we sink Deeper than the night Step by step, we lean Into the underground [Chorus] Pulse of the underground Hold me, hold me down Pulse of the underground I want your heat in my mouth Pulse of the underground Don't let this love slow down Pulse of the underground We burn, we burn, we don't come out [Bridge] If the morning comes too soon Leave your shadow in my room I'll keep your rhythm on my skin Till we meet the dark again [Final Chorus] Pulse of the underground Hold me, hold me down Pulse of the underground I want your heat in my mouth Pulse of the underground Don't let this love slow down Pulse of the underground We burn, we burn, we don't come out
