This image has a number of memorable erotic motifs of which the most obvious is the 'Beauty and the Beast' theme (or perhaps it should be youth and age?) The older, kneeling man is a veritable satyr seemingly covered in hair and the embodiment of lust. The portrayal of his captive does not suggest innocence either, the pugnacious face, nipple ring and clumpy boots all suggest he is an tough, experienced hand - but possibly not quite prepared for this ordeal.
A powerful sense of threat is produced by the caveman-style, spiked club and the array of various sharp-edged tools scattered around. Orez pushes the menace right to the edge without quite resorting to Greasetank-style explicitness. The bondange depicted is refreshingly uncomplicated, but still chillingly effective - the young man's manhood is uncompromisingly secured to the flat top of a symbolically saw-off tree-stump. Tom of Finland also employed lumberjack images involving sawn off trees but as far as I can recall he never made this freudian association (although he certainly flirts with the threat of mutilation in later work).
