Miss Petra shows up in a sexy black vinyl dress and gets ready to go out, but it doesn't come to that.
Her neighbor does not want her to go out and ties her up tightly with ropes on a chair. So that she cannot call for help, a gag is put on her first.
To increase the fun a bit, her neighbor tries several gags on her. Tied on the chair she has to helplessly endure each gag.
A ball in the mouth with tape over it, a pump gag that is pumped up tight and makes her really dumb, or the mouth stuffed with a cloth and Cleavegag plus tape.
No matter how she is gagged, she can't get any sound out. What else would you do to her?
