I really hope you've got your clamps nearby. I think putting a clamp on each nipple of yours is way better then pinching them, don't you think too?
If for some reason you haven't got some clamps you can use, then you are in a really bad luck, because it means punishment time.
Bad Boys won't get any pleasure, neither today nor the next two days. For the next two days you'll do one punishment-tease per day. If you're told to stroke within these days, you'll slap your dick instead!
Don't forget to squeeze, boys *grin*
