Mistress Miranda demonstrates her inflation sack to Mistress Sidonia, as they both prepare a slave to be encased and used. He has electro pads attached to his nipples and groin before he is put in the bag and prepared for full inflation. When fully inflated the electro boxes are connected and the slave is stimulated in waves, which become so intense he ejaculates without any direct stimulation. Following this, the electrics are turned up and he is made to cum for a second time, before being left in the sack until the Mistresses decide to torment him again.
