I don't know if it was mentioned because I haven't had a chance to read all of the entries yet but...
Lexi Belle vs Boz. If you iafd/google it you'll find the scene. He kills her pussy and then she unexpectedly squirts. She says she didn't know she could do that and seems all embarrassed. And then he kills it again. Really quite a shame she doesn't do IR anymore. Perfect balance of innocence and willingness early in her career. Really dug that about her. I can't really think of an active star that pulls this off. But I digress. One of my favorite all time scenes. When I say boz kills it in this I mean he fucking annihilated it.
And I'm only up to page 3 but this one poster, Cheapshot is relentless in his pursuit and documentation of destroyed pussies. Just wanted to say thanks. Found a couple of scenes I've never seen before. Keep up the good work.
