Hi thelorax, yes I'll chime in and say great pics too. Try taking the rubber ends off the clamps, that will add to the sensations you experience - be warned though you WILL need to use the tension adjusters if you have sensitive nipples. And you can remove the balls and add a length of chain if it is your desire to have one.
How do I know this. Have the exact same set here. Have fun and look forward to seeing more of you.
