23 [F4A] Tell me your dirty secrets

I want to hear about your non-mainstream/taboo experiences. Tell me what you've done that you'd never confess to someone in real life. No Limits! No matter how dark, depraved, creepy or non-con.
Have you been drunk and done something you shouldn't have? Or maybe you planned/watched for months, fully aware of what you were doing.
This is not about roleplaying, I want real, honest experiences. I'm very curious and will ask a lot of questions. I will not judge anyone for their perversion so be as open as possible. Guys and girls welcome!
So there it is! Let's see who can shock me today...
