I felt that this slave needed a little encouragement to aid his ability to suffer for me, so I mixed up an energy cocktail of my very own to refresh him throughout the experience! He was very eager to drink, which may have had something to do with the fact that I explained how he would be caned hard, for as long as there was liquid in the drip feeder! His frantic sucking on the tube was to no avail though... I made sure he got a good hard thrashing with rapid and relentless strokes, just as he was consuming the final drips!
