Good horse and tack shops offer a wide range of gear to suit wide ranging needs of horse and riders. I find myself scouting them regularly, looking for items that can be pressed into service.
This is an Off Billet Strap. It is used to attach the girth to a saddle on the off-side of a horse. It is a beautiful piece of leather.
I found this one made of thick leather, 2 inches wide and 18 inches long just begging to be put to use in a session.
As for severity, when used with force as most mistresses tend to do, I find it nearly as effective as the Canadian Prison Strap. That’s why I named it to a mistress as ‘The Prince Of Straps.’
Do be careful if you mail order one. Some are now made of nylon (and that just will not do). Some are narrower and some are made of latigo leather which just does not look anywhere near as good as the one above.
There is also a half breed strap used in a similar way for attaching a girth to a saddle. This is over twice as long and while I don’t own one, it looks a little long for our specialized use. Then again, when it comes to collecting gear fopr BDSM play, all straps are good!
