Yes, Joanna was plenty big enough, as Bill Dobbins showed in his B&W photo set of her topless in the pool before she was done.
Unfortunately, I expressed my true thoughts to Joanna after her OP, and she was somewhat upset with me about my opinion, and said she thought that if she had a sock down her knickers, I would like her better! Not the case of course, but I took the point. Her implants were for her, and if men like it or not, tough.
Silly reason to upset an FBB, which I'm not proud of, but there you are, live and learn.
K for the gif's Street Fighter, I must learn how to do them.
