Just a few anecdotes about cock suckers.
The best little cock sucker I ever met was this single mom from Brampton. She LOVED cock, loved sucking cock and it was always CIM. She blew me one time (of course, taking the load) and then about an hour later, blew me to completion again. I remember I said to her, "you don't need to do it again" to which she responded, "no, I love sucking cock and I love pleasing men" She just had an incredible talent.
I remember one time meeting this British nurse from Lava Life and during our phone conversations she told me how much she loved sucking "willies". I remember when we finally ended up in the sack, she demonstrated over and over that she truly did LOVE willies and would actually ORGASM just sucking cock. I thought that she was one in a million, then I met another British nurse (seriously) who LOVED sucking cock and she would come just sucking cock as well.
My last serious GF told me that she could easily suck cock for an hour and she demonstrated time and time again that she could. She always took the load either on the face, or in the mouth and would swallow. She was a fantastic cock sucker (too bad she was also a ball buster, but hey, that's another story). She would use her hands to massage my balls and shaft and suck at the same time till I was practically unconsious.
My one long time GF was also a fantastic cock sucker. Alway CIM or facial, though she would spit (maybe a half point loss for not swallowing, but not that big of a deal). What I loved about her is even when I would come home from a strip joint and was too tired to fuck, she'd just start to suck and I'd blow my load and fall asleep in about 5 seconds and she just loved pleasing her man.
So, they are out there.
