Tiffany of XXXtase and Chloe Milan. That is really about it since their retirement is just recent.
As for the escorts who have retired long ago. Yes the experiences were definitely amazing and should remain in the past. Remember many of these ladies have surpassed their sweet prime. If you run into them it would be somewhat of a let down. I am saying this from personal experience.
She retired not so long ago, but if a comeback happen I wish to see Zoë (indy) again .
Another i'd love to see coming back would be Marie-Eve of Asservissante. She'll be my selection for tomorrow.
