Tuffdude and Extremetop’s slave MarylandMasoBoy gets put through his paces in Master’s gym. First, a long warm-up job on the treadmill to bring up the boy’s sweat. Master stings the boy’s ass with a buggy whip to keep the stride going strong. Then onto the shoulder pull-down machine. As Sir, demands more from his boy, he uses a whip to get his point across. Next comes the bench press. Sir coaches his boy on proper form and uses a pair of clover tit clamps to reinforce his coaching points. Then comes a set of cable-crossovers. Finally, the scene ends with some ab crunches. Master is proud of his boy’s effort. Soon that body will become a muscle hunk and the envy of Kinksters everywhere.
