Relationships
Step-Sister
Short Definition
In BDSM, a step-sister is a person, usually femme, who has an extremely close non-romantic relationship that is, can, or has been sexual and/or kinky. This is much the same as a sister but without the incestuous overtones, which aren't for everyone, particularly in a sexual context. Often used by close friends in the scene who have been described as “as close as sisters”.
