Beginners guide to SPN kinks

[raindrops1mil.livejournal.com]

Weird search but... I have some friends who are new to the whole 'kink' thing, yeah? And I want to get them into it, but I don't want to pick the wrong story and scare them away. So I was wondering if you guys knew any 'beginner' stories for kinks like:

- Knotting
- Animal Transformation (Like Werecat or Werewolf type fics)
- Bondage
- Mpreg
- Basically, any kink except for Watersports and scat, yeah? :DDDDD

Looking for mostly Wincest (will except Destiel) and all must be Bottom!Dean. 

Please and thank you~
