Erotic spanking is the act of spank another person for the sexual arousal or gratification of either or both parties.

Activities range from a spontaneous smack on bare buttocks during a sexual activity, to occasional sexual roleplay, such as ageplay, to domestic discipline and may involve the use of a hand or the use of a variety of spanks implements, such as a spanking paddle or cane.
