Hard Boob biting and squeezing

RANT WARNING:

Boyfriend constantly pinches or sucks really hard on my nipples and I seriously don’t like it. I’ve tried to tell him so many times and he laughs and says “you know you like it” I REALLY REALLY DO NOT though. I had my nipples pierced for years before I met him. I took them out bc he wouldn’t quit pulling them with his teeth. He just doesn’t get it.
