That's true - it's a weird feeling, isn't it? You enjoy their soft-core photos so much and for so long, and then it's a bit of a shock to see them doing the raunchy stuff. Ah well, I won't lie and say I don't enjoy some of it...
If anyone is interested, here's the full DVD rip of Angel Perverse 3 - which contains a scene with Julia (as Juliya Sunrise) that I've not seen anywhere else. In full disclosure, this is not my upload, so thanks to the original poster!
