Have some femdoms attach a Venus 2000 milking machine to your cock. Tie its power source to a computer random control that turns it on between 3 and 5 minutes and turns it off 3 to 5 minutes. At the same time a dildo machine will randomly be pegging your ass between 3 and 5 minutes and stopping for 3 to 5 minutes from a separate computer. They will be totally independent of each other. Your only hope since you will be edged crazy will be to beg the femdoms to let you be their chastity slave.
