We played with rope! MDR and I have some lovely red rope that we like to use, and he decided to practice some things on my feet. Foot rope bondage can be really useful. Spread the legs, hoist them up, hold them in place...very versatile!
I definitely recommend playing with rope. I don't mean going to classes that teach kinbaku, or even western rope, though those are awesome if you can find any groups in your area that teach. But there's something nice about just getting out rope and doing stuff. Throwing it around, playing with knots you don't know the names of, and just getting the feel of it.
