I'm tired of having you at the store, free to roam around and touch everything, free to talk to the sales girls. Slave should be kept under tighter control in public. So, this time, I want to make it more interesting. I'm going to have you caged and plugged with a vibrating device controlled by me. You'll be gagged beneath your mask and handcuffed beneath your scarf. It'll be so funny seeing you subtly attempt to get your wallet out and pay without letting the clerk know you're handcuffed! This shopping trip will be so much more fun.
