Biggest in length, belongs to a close friend of mine (and best man at our wedding), who was packing a nine inch cock that she was obsessed with, and stretched her more than she had ever experienced until...
...until she met and started fucking this guy, who had a BBC that was a little shorter at just over 8 inches, but was so thick she couldn't touch fingers when she wrapped her hand around his cock, and stretched her more than any man ever has!
