I'm not Jupiter Lake but inevitably get drawn into these memory-lane type posts. Of the houses you mentioned that I sessioned at...

Angel Stern's: the all-time great Veronika, Lady Helena and a tall blonde German mistress named Hildegard were my favorites there. Interesting one-off sessions with Intensity and the infamous Nia, and a couple of sessions with Robin Byron.

Paradise Lost: A good session with a mistress named Olivia, who I don't think was around for very long. (Not the Olivia from Hidden Chamber.) And then a very good session with Velvet, who went on to work at other houses.

L'Oeil Cache: Only made it there at the very end and had sessions with Nadia and Scarlett Cross.

Most of the above sessions were booked on an hour's notice. Different times!
