Why am I not surprised that you tried to find something appropriate for your tits? Good girl!
Small rubber bands around your nips might have done the trick. You just need to make sure they have the perfect amount of pressure since you would be wearing them for a longer period of time. But imagine how sensitive and tender they would be after a while.
I am glad you are about to (or already did) bend some of those damn public decency laws. Photos are very much appreciated of course. 🤩
