I noticed this on 2 separate occassions now.  I saw a girl about 2 years ago, then when I saw her again recently I thought I noticed a significant increase in cock girth.  The session was awhile back and I chalked it up to bad memory on my part.   Then I saw another gal a few weeks ago that I had previously seen a year or so ago and the same deal.  THis time I'm sure of it because I had a great session the first time and distinctly remembered her cock being nearly an exact mirror image if mine.  This visit, the length was the same but she was waayyy bigger around than me.  In all cases the gals were hard as a rock so I can't attribute it to being harder one time over another.  Just curious, are there operations or procedures going on where the gals can increase cock girth?
