I really liked the glimpses of the other universe we got. Someone mentioned on a previous comment the flipside of the coin a society based on bdsm must have and i'm glad we learned a bit more about that. A relationship like that, without an option to say no, without a safeword, seems very dark and intense to me. You've portrayed the whole surrender/absolute trust thing very well but the concept skirts close to my hard limits.

Regardless, I'm definitely enjoying the story, can't wait for more.
