A step-by-step instruction with 25 photos on how to make and use a lockable cord to prevent taking clothes off. For less than 10$ including the tools. Can be used for both bondage and self-bondage. Or just to spice up your daily life. Click on the image see the article.
Let me know if something is not clear enough or you have other ideas!
BTW, the water-polo swimsuit (Speedo hydrasuit) from the photo is still locked on me. With pantyhose underneath, of course ;-)
