The Sissy Slut does the house work for her Mistress, and of course as usual she is dressed as a maid and hindered with a Chastity device and anal plug. During her work she finds a small key. After 4 weeks locked up in Chastity she can not resist the temptation, of course ... but that is not the key for her secure lock and unfortunately just at that moment her mistress comes into the room to check her work. The punishment follows, of course, immediately and with power.
