Hmm, been a rough day. You were tired as hell, wanting to rest, but one thing that needed to be handle first, was needing to take a bath, sweaty and stinky. But, as you were heading to the bathroom, you heard the water running and... singing? You quietly peek through the door and there he was, your partner, covered in water and bubbles as he was using the scrubbing brush as if it was microphone. His eyes close so he didn’t know you were there.

(Yes, I have been away but calm yourself down, I was taking a break away, so here, something to play with)

You already have established relationship with him so have fun with your partner.
