Okay... let me try.
Get some rather thin rope and tie off your breats.
Then you take hot sause (really hot!) and massage it onto your nipples.
if they aren't hard yet you have to get them standing but without removing the hostages from your fingers. once they're like that get a really fine cord or a string and tie it around your nipples. The other end of the string should get fixed so something high up and in a way that you have to stand on your toes so you wont ripp the sting. Now just stand there for 10 minutes.
Have fun
