So have you ever seen an ice lock? One end will be locked to my D-ring in the crotch. The other end to the plate on which I will be kneeling. Once I'm locked I can't stand up anylonger to get the keys. I will have to wait until the ice melts and the two cilinders can be separated then.... What an evil technique to make your suffer Rubberwhore for ypu 😈😋😜👄💋🔓⛓️
