I remember I got the affair ending after maxing at 200 sluttery so I don't know what other ending is there. Unless it involves other characters?
Currently you can only achieve endings on your own or with Annabell if you're following the full corruption path where she stays with you. Other characters will get their endings at v1.0.
If you're on your own, you can reach the escort ending and the stripper ending if you've performed a certain number of tricks/strip shows.
The two new endings relate to an event during Day 6.
