Kicking The Slave In Public

I took the slave to the top of this hill and truss his arms and gams to the massive posts - on the brink of a pit - then I commence to aggressively kick his figure - while joggers and bikers pass along behind us! With the slave trussed like this I can ideally kick his bod over and over again - and he cant get away from me or even protect himself! I wonder what all the passerby thought of my human punching bag?!
