Looking for a humiliating & degrading gag

[BobBobington]

My gf/sub (25) like all kind of kinky stuff but she really likes stuff that are "wrong" and "dirty" and we're looking for a gag. So far we've tryed ball gags, tape gags, and panty gags. But were still looking for some more wrong. See if you can help us?

her limits include pee and poo.

A (small) rubber duckie.
A shoelace.

Make holes in rubber duckie. Put shoelace through rubber duckie. Apply as ballgag, facing outwards.

Quack quack.

Squeaky dog toys made of rubber. Get a bone-shaped one and tie lace to either end.

Tennis balls. Cut a hole in either side and thread lace through the middle.

Gob-stopper sweets. Slightly more difficult, drill a hole through the middle for to thread lace through. Tastes good lol.

Dildo. Tie lace to either end like the squeaky dog toy.

Small plastic drink bottle. Bottom of bottle inserted into mouth, lace looped around neck of bottle and tied round the head to hold it in. (This could also work for the dildo if you wanted to insert it into the mouth vertically instead of horizontally).
