more flexibility for bondage can also be achieved through bondage.. If the Dom is willing to take part in the flexibility training... He gets to ty you and watch you in the bondage ;-)... if you can´t reach a position the Dom can bind as close to it as possible and leave you in it for 15 - 20 minutes max, do it a few days in a row and you will realize that you will come close and closer to the position you wish to achieve.
