I love to be put in a Posey Straitjacket. For me that is the ultimate.
I also like police type metal handcuffs and leg irons.
In addition, other types of hospital wrist and ankle restraints as well as finger control mitts.
In summary, proper institutional restraints rather than bondage kit.
However, I also like simple rope bondage (hands behind the back and legs together or apart) either on the floor or secured to a post or chair.
What is also good is to be bound in pashminas (the cheap 5 for £10 types you can get anywhere in UK). These are soft, comfortable and inescapable if applied properly. I go a lot to Chinese and Thai massage parlours and have usually managed to persuade (it doesn't take much effort and the girls all seem to quite enjoy it) the girls to tie me up for a massage.
Also, I'm new here so Hi! I love the site.
