It is always a pleasure to use the strap or belt. It makes a particularly satisfying sound when it lands on target. It even makes a lasting impression over jeans when they are stretched tight like a kettle drum across a girl’s bottom. It does, however, require some practice and skill to be used correctly.
If she is receiving a strapping while bent over, as opposed to lying face down, then the belt must be kept in constant motion so it does not bend or twist because of its flexibility. Some people prefer to use a strap on the miscreant while she is lying face down on a bed or sofa. The strap is easier to control this way as it is coming down in a vertical line and less likely to twist or bend.
Either way, the strap is an excellent implement and has the advantage of being immediately available around your waist whenever needed.
