I've worked on this for a couple of months. I could honestly put many more months of work into it, but I had to stop for my own sanity. Essentially, this is a supplement for Pathfinder Second Edition focused on ABDL and with minor looks at other kinks, like oviposition and vore and stuff. I can't guarantee it's balanced for sure but I've been collaborating with a couple of other ABDL friends that know the system in and out and have myself compared a lot of it to the rest of the existing official things to try to make sure it isn't too egregious, so it should be good to run with. If anybody wants 2 take a look feel free, if you ever play with it let me know!
