Did I take everything? good, now you can untie the weight and the second shoelace, but do not put them away we will need later!
now place the basin where you want, on a chair, on the floor, I do not care, as long as you can completely immerse your balls in the ice water.
It is not pleasant? after a lot of work a nice cold bath is what it takes, I'm good masturbate, keep your balls immersed with the strong hand and the weak one masturbate, enjoy a little 'pleasure, edge if you want but do not cum absolutely!
if you edge completely plunge the cock together with the balls and keep it in the cold water until it becomes soft, then start again, always balls in water, continue for mhh 2 minutes?
