I was wondering if there were other sites that used this or similar programs for scripts. I've pretty much tried all the ones I'm interested in here, so I was wondering if there were other sites that had sex scripts like these?

You've probably already heard of Milovana
There are some other programs out there, with various levels of bugs. Here's one: https://milovana.com/forum/viewtopic.php?f=26&t=23382 I found them through old Milovana threads, but I couldn't get them to work enough for me.

You may find 2 previous ones also (PCMistress and Cybermistress ?), but they are quite old and no more maintained as I know
