Impact play is a human sexual practice in which one person (the bottom) is struck (usually repeatedly) by another person (the Top) for the sexual gratification of either or both parties. It is considered a form of BDSM. There are number of activities that qualify as impact play.
In erotic spanking the sub is struck either with the top’s open hand, or a rigid implement such as a paddle, cane or riding crop. In the latter case the activity is often referred to as paddling, caning or cropping. The usual targets for spanking are the buttocks and inner or outer thighs.
In erotic flagellation the sub is struck with a flexible implement such a whip or belt. Whips are classified by how many falls they have:
- Single tails such as a bullwhip have a single fall. The associated activity is referred to as single tailing.
- Floggers, such as a cat o’ nine tails have many falls. The associated activity is referred to as flogging.
