Two Girl Tie Ups

My idea would be for Monica to tie up Abigail in part 1 then for the roles to be reversed in part 2. Both would be dressed up in all black, satin blouses, skirts, ect. One w/ collar buttoned, the other would be a tie bow type of blouse. A possible part 3 would be both ladies tied, one on a chair, the other on the floor. I'd like to see ball gags used, but tape would be fun also. Thanx Bob!
