The Troika

The two matched stallions pictured on the left and right of the first  picture have served their master well over the past two years as his personal pony-slaves and he contemplates using well into the foreseeable future. 

However, conditions change and because he now has to travel greater distances, their owner recently purchased a more luxurious carriage suitable for his long trips. But luxury comes at a cost and the new carriage is larger and heavier than his previous one. While he has no doubts about the ability of the two muscular stallions to cope with the heavier load, he nevertheless requires that now, they run at greater speed over longer distances. Therefore, he has added a third slave to assist thus effectively turning the team into a troika.

The new purchase is an as yet, untried young colt fresh out of the training stables but guaranteed by his former trainer to be a good performer with great stamina and pulling power who responds well to the driver's whip. The colt will be harnessed to run between the two stallions and he will add that extra slave-power needed to pull the heavier load. 

The picture shows the two stallions welcoming the new colt and no doubt, they will greatly appreciate his physical contribution in sharing the heavy burden of pulling their master's new carriage.

And of course, there is another reason why they are enthusiastically welcoming the new colt as is evident in the second picture. Of a night time, alone in their stable, the colt will become their filly.
