I think you will find it mostly disappointing, but the same group (Nightmare Express) has some interesting sets. Most of them end with the girls mind broken or pregnant (or both), but they have quite a lot of asphyx (with some sets ending with the victim dead)

Be warned though, there are lots of futa, and not all the sets have good art (with some of them being quite shitty)
