Unfortunately, they’re out there. Some girls that are extremely self aware of their either big tits or bigger body size that comes with them and will say it’s a very demeaning act. They equate you fucking their tits to pretty much insulting them by way of sexually calling them fat. Some girls take that shit to heart and are very against the act. Ran into a few like that, easy D-E cups. Were very much against it. Kept moving. Billions of tits out there, respect the process and don’t waste time on those not using em.
