In the BDSM community, CNC stands for consensual non-consent, also known as rape play. Although it varies scene to scene, it's usually an extreme power exchange where, according to previous negotiation, there is a victim overcome by a predator by force. People who enjoy this play often enjoy either the extreme lack of control or extreme control on either side of the exchange.
**this type of scene does not encourage ACTUAL rape. All proper scenes are done after much negotiation between of-age, consenting adults.
Me and Billy did a CNC scene last night, I was so scared I came 4 times.
