Thanks for the responses guys. Very few Vanessa$/Valerie quality MILFs out there these days, or so it would seem.
So why not her, what appears to be stopping you visit her?
I sent a message to Sophia the moment I spotted her profile. It's still unread as she hasn't logged in since the 25 of February. As that was only three days after she actually joined Adultwork, I'm guessing either she changed her mind, some lucky devil snapped her up on an exclusive basis or she's on holiday.
I live in hope!
