In reference to the female anatomy, soft leather straps are the most appealing form of restraint for the wrists, ankles, arms, legs, waist and chest (above and below the breasts). A straitjacket would also be great, but only those with the double crotch strap so as to keep the crotch clear for "treatments".
Straps that are too narrow and cut into the skin, which is not permissible in my research. What widths do most people see to prefer. Squeeky leather (makes a sound when stressed) seems to add to the experience.
When a vibrator is applied, it is important to keep the hips immobile and unable to move aware from the device. The thighs must also be keep at bay due to the powerful muscles.
Anyone have any stories of successful restraints, do's and don'ts?
