I have taken the rubber bands off of my mail here in my office, they are big and wide, and put 5 around each one of my large tits. They have become quite engorged. My nipples are hugely erect. I'm wearing a plain (no pattern) shirt and my nipples are so erect they are poking through the shirt. My boss came in and I really enjoyed how he struggled not to look at my hard as rocks tits and nipples. I know he wanted to jump over the desk and bite them.
