A Filling Station is a slang term used to reference a willing male or female concubine or sex slave. Filling Stations are also known as a cum dump. Filling Stations may serve one master or may be shared among several. They may also be shared during group sex and orgies and service multiple participants.
Tonya was looking forward to the orgy she was attending on the weekend. She enjoyed playing a submissive role and being the sex group's Filling Station.
