This slave is in bondage to his female dominant in more ways than one. He is there to serve her every whim and if that includes crawling around on the floor on his hands and knees to fetch things – so be it. If it involves being bound and flogged then that is his fate and he accepts it.
Oh, but besides the psychological bondage there is also the ropes and chains sort. Then a male slave is truly bound for pleasure (not his own). Femdoms have such imaginative ways of binding their slaves too. Let the men stick with the plain rope. A Mistress might use a pair of pantyhose or even a garden hose or a specially made chain wheel, the possiblities are endless!
