Well quite a few of the girls in the your list seem to be either retired or semi-active, and its gonna take alot of money to get them back on camera and maybe not even then. There are actually quite some fine new boobies floating around, just that they were never properly utilized, especially those on DDF or Scoreland.
Well I took a peek at some of the scenes in POVJF5 and honestly I'm not liking what I saw. Some scenes had WAY too much spit, and there's barely any decent 'Jugg-Fucking', just lots of squeezing in slow-mo. I mean c'mon how is that supposed to feel better than some smooth, continuous cleavage action? And don't get me started on the jackoffs. My biggest concern is probably the male talent. They seriously need some variety considering Darkko is just jacking and Kevin's performance isn't all that great either.
Honestly though for me it doesn't even need to be just all oral and tits, you could throw in some vaginal or even anal if it helps you sell more copies, as long as the finish is between the tits. I do appreciate the thrill of chancing upon these gems every now and then but it would be great if there's a go-to series that I know I'll put my money on.
