A term that describes a person or preference in the realm of S&M and bondage where the desire is for pain and/or restraint but not to be marked in any way. ie. no knife play, burning, whipping or deep bruising. A way to elaborate during the discussion of limits before play.
Sub: I'm mostly into no marks masochism. I like being spanked, choked, hair pulling, slapping, scratching, biting, nothing that will require intensive aftercare.
Dom: No marks? Cool, thanks for letting me know, I'd like to know what your limits are for breath play, and how much restraint are you comfortable with and with what materials?
