The feeling of having sore cheeks after giving a bj the night before, especially prevalent when it was a perticularly intense bj, or it has been a while since you gave your last bj. Makes it difficult and/or painful to do any other activities involving sucking, even light sucking, such as kissing, drinking through a straw, etc.
Hey, could you get me a spoon for my smoothie? I have a bad case of bj cheeks.
She was so amazing last night, poor girl must have bj cheeks today.
