The premise for using this erection enhancer is simple: Throw this baby around your untamed longhorn (or unruly calf - one size fits all) and proceed to hog-tie it into plump submission. In other words, open the noose to its largest size, slip it over your cock and balls and tighten, either by pulling the soft plastic ends in opposite directions or sliding the clasp snug. (Dry, non-lubed fingers work best for the tightening maneuver.)
