Why simply write “ritardando” when you can build it into the music?! Starting halfway through the third measure, Brahms begins augmenting the rhythms, stretching things out from triplet eighths to normal eighths, then to triplet quarters in measure 5, and and finally to normal quarters in measure 6. This creates the effect of slowing down even though the tempo remains the same. A neat little trick if simple isn’t your cup of tea.
