Aching To Cum

The slave hasnt cum for many weeks, having been secured in chastity, but hes finally been promised a release... but a release with a twist! He can only cum if he takes a huge amount of weight tugging on his testicles. His excitement is clear to see, especially when the industrial vibrator is run down his shaft, but the pin wheel and weights make the whole ordeal an intoxicating mix of extreme discomfort and uncontrollable pleasure.
