Wire bondage can be done a couple different ways one is to use thin Picture frame wire to tie a noose around base of each tit pulling it very tight go around tit a few times making even more tighter then twist wire and cut wire with a wire cutters.
Make more nooses around the tits tying tightly leaving space between wire bands tied on each tit.
Depending on how large the tits are you can tie the tits with a ½ inch interval between the bands of wires and do the same to the other tit.
You may get 5 to 8 wire bands around each tit.
Now take the wire and push the wire under all the bands on both tits and bring the 4 to 5 wires up and over each tit. Take middle 2 wires and wrap around the nipples and tie. Push the wires under the bands and bring to base of the tits do the same to the other tit then tie the wire at the band at the base of the tits
You can tie many more strands of wire up and down over the front of the tits.
You can tighten the wire with a needle nose Appliers then bend the sharp edge of the wire into tits so it stick in the tits.
Once all the wire bands are in place you can tighten them even more by grabbing the wire in the jaws of the Appliers and twisting it more to tighten the wires.
