Hi Prince,
Kristen, now Evie, was a Positive from me but she is early 60s. Don't mind myself as her age is similar to me.
From what Brad and Cupid have said she is a very nice lady, physically good and fresh in the right places, and a nice discrete home in Branksome. Looks after herself and I don't think you will experience the Negative that you had with Busty Anna if you decide to pay a visit.
However if you really prefer someone genuinely in their 50s suggest you look at XxxSuzixxx. You won't be disappointed.
