The popularity of private slave sports is really soaring and beach volleyball is considered to be one of the great ones to use your slaves for.  Look at the advantages - you only need a few really good-looking slaves, unlike in , say, rugby; it’s not expensive to set up - all you need is a net, and an area of sand, which is there if your estate is on the coast, or easily made if not; and the constant leaping around really shows off the athleticism of the slaves’ bodies.  What’s more you can relatively easily train a new slave to play well, unlike, say, soccer where a certain amount of innate ability is required - so it’s easy to vary your team from time to time, and can have a variety of slave sizes to view and enjoy.
