Underbelly is an Australian television series, based on the real life events of the 1995–2004 gangland war in Melbourne (and also, it has to be said, on The Sopranos). Episode 5, first screened on 26 March, 2008, included a scene where drug-dealing gang boss Mark Moran (Callan Mulvey) indulges his discipline fetish by spanking his lover Danielle McGuire otk on the bare. There’s only one swat in the end but the build up is steaming hot!
Danielle is played by former Neighbours actress Madeleine West.
Update: A prequel to this series called Underbelly Razor began airing in 2011 and the first episode saw yet another excellent spanking scene. Watch Anna McGahan spanked in Underbelly Razor here.
