Encased in rubber and wrapped in plastic, the two mistresses tease their trussed up slave. His air is running out as his body is used to wriggle on and his face used for pleasure through his mask and plastic. His cock is stiff hard and trapped-encased in layers of rubber restraint. A small breathing pipe is given to him as respite, his head squashed in between his mistresses legs. His cock is slowly released and played with, while his mouth is used the other end.
as his breath runs out his spunk builds up and finally shoots its load.
