A cattle prod is a BDSM device commonly
used in erotic electrostimulation. Electricity runs through the
length of the rod, and is conducted through pointed metallic ends.
Often, this leaves a mark or two on the receiver's skin. This will
scar and peel off naturally. A cattle prod is a good way to vary
electrostimulation points. Contact points are left to the whim of the
dominant partner. However, it is very, very important that those who use a cattle prod do so safely and keep their partner's limits in mind.
