For breasts, the only strict limits I recognise are:

Don't tie and beat, one or the other but not both. Tied breasts can't bounce away from blows.

Whatever you may have seen in pictures, don't run needles through them. There are a lot of big blood vessels in there, and no way of pressing on one if it starts to hemorage.

For nipples, having seen two women breast-feed, I have very few limits. They may be deliciously sensitive, but they're tough. I once put clover clamps on a slave's nipples and strapped them down with tape, and then (I blush to admit it) forgot about them. She was too obedient to complain, and I didn't remember them for several hours, by which time her nipples were black. But in half an hour (with some massage, which made her whimper) they were back to normal, and none the worse except that they were super-sensitive the next day! I don't recommend anyone try this on purpose, but it does show that you can get away with a lot.
