I will answer this as per the title - only girls with an expectation of incoming goodies actually keep my membership, past glories only wouldn't make anyone maintain a membership, after all.
Still hard to keep it to 5
1 Linda Sweet - gapes, double anal, piss, hard nasty stuff and works well with other girls
2 Karina Grand - another girl who pushes the envelope. Takes is deep and hard and her flexibility makes for really good anal positions
3 Anita Bellini - Really pretty and her pissing scene elevated her to the next level for me
4 Susan Ayn - looks more gorgeous with every scene. Another piss friendly girl who still ranks amongst the best anally
5 Cathy Heaven - only 1 recent scene, i know, but i suspect we will see more if her. Deep throat and an ass you can fuck as hard as her pussy. Love her gym body as well, makes for a bit of variation.
6 Tina Hot - fuck it, i know i only have 5 but she is gorgeous and returning

Lots of others besides ofc but of those I expect to see new scenes from and expect the best, these would be the ones I'd most look forward to....... though if Henessy could be persuaded to double anal or piss the list may need revising

(love to see Misha Cross, Nataly Gold and Sandra Luberc back for more intense scenes too!)
