I don't mind my boobs being touched or squeezed, I just hate having my nipples bitten and I hate it when they squeeze too hard.
I had a man on top of me the other week while using my boobs to hold himself up, was fucking agony.
Our boobs are full of glands and they really hurt if too much force if used especially on the run up to time of the month.
As I said, I'm fine with most things in moderation. When some people take things too far is when it becomes uncomfortable but that can be said about practically everything sexual like kissing for example, fingering or giving someone deep throat. There's always someone who wants to devour your entire face, finger you dry and stuff as many fingers in as they can with raggy nails and then there's always someone who wants to force their cock so far down your throat that you vomit and that's just a few examples.
It must be really difficult to be in a job like this when you really loathe having your boobs touched OP
