As the guys at bigtitscurvyasses always exaggerate, I'd clearly vote for a "normal" J cup instead of the JJJ mentioned here. Kristina Milan started with a K cup, but now she is referred to as having a KKK cup which is pure nonsense. Kristina's and Vanessa's boobs have approximately the same size, so the J for Vanessa and the K for Kristina makes sense.
