Pam has had 3 and I was present for each of them. Her first was four years ago, which we've posted about elsewhere on this site, and she continues to enjoy his delights several times a year (exclusively) and has no ongoing interest in anyone else! Her first and current, was an old university friend and roommate of mine, Edwin! Her second was Edwin's twin brother, Eduard. Her third was a friend of Eduard's and was a once only event. He just didn't measure up so to speak. Eduard has had several sessions with Pam but he's far from Pam's favourite. Edwin wins her trophy!
P.S. That pic we use in our Avitar is one I took of Pam just before they were removed by Edwin and she got blackened! Evidence of just how horny Pam was at that time is clearly visible via the pussy juice stain right down the middle of her crotch!
