This is going really great, btw. No black eyes... but hey, I'm kinda starting to like the idea of it. We have discussed ways we can excuse it (like going to a (metal/rock) concert the night of the black eye and blaming it on the show getting rough...)
We are enjoying exploring it together and it's Read more… really a treat. It's brought us so close together so quickly it's hard to believe. We barely leave each other's sides. Thank to everyone for the great advice and wish me luck going forward.

She has done a great deal of research and has a particular technique in mind. This will be done in a controlled way. I'm also interested in waiting because I've only ever fought for self-defense and I have honestly lived a life where it came up a lot. I've fought hundreds of times and I didn't use Read more… restraint, now I am learning to control how hard and where I hit, but it's going well and she loves the outcome so far. I also have never hit a woman (goes without saying), so I'm learning to adjust to her anatomy (much more delicate than a man's). GREAT care will be taken to ensure no permanent damage is done. The more likely outcome would be that she gets no black eye, and we try again another time.
The second part of your post brings me to a VERY important question. I want to have a waiver/contract that states this is of her choosing, without coercion/bribery/etc. I need to know more about how to draw up such a document, but it may be better to post a new thread. Hell, there may be 100 threads about it. Someone here might know exactly what I need (website/resource/etc.) to help me draw up such a document. We will get it notarized and I will keep multiple copies. Equally or MORE importantly: Do such documents offer any protection from legal action/police interference? This is a subject that is very important to me. I want to understand more because I would be much more able to relax and enjoy myself knowing that I won't go to prison because the state doesn't believe her when she says it was consensual. Thanks in advance for any stories/resources/assurances that anyone can offer on this subject.
In all honesty, I doubt it will come to this. We are sort of past the point where she could flip and start trying to have me locked up. She hasn't, and I did trust her before that point. I just think this is important because of third-parties (parents, friends, hospitals, police, etc.)

It's a thought... or I could just have this conversation with her. It is her best friend after all. But I think it's not jealousy. As I hear it the girl is more dominant than submissive. I'm afraid that vanillas will never understand what she and I do, regardless of explanations. It's all way more Read more… passionate and loving than I ever realized. The aftercare, alone, is amazing. I am so enjoying the time I spend with her that I really don't care what others think about it, beyond them thinking that I am abusing her (I'm not.)
The others who denied her the chance to play out her fantasies were abusing her by denying her the chance to explore her own mind and body. It feels good to be the one to do that for her while at the same time exploring my sadistic side, which I always kept under tight lock and key.
