The Training of O is a great site. They used to have a four-day shoot with a model who was being trained as a submissive. There is a lot of bondage using creative positions and implements. Newer scenes aren't shot over four days but they are still pretty good.
Sex and Submission is another Kink site worth looking at. Most of the scenes have some great bondage in them.
Public Disgrace is another Kink site I used to like. I love public nudity and sex and adding in bondage to that makes this even better. I don't know if they are updating now or not, but it's worth checking out.
Considering that a membership to Kink gives access to all their sites, you should sign up for that. I think you'd like it.
The other sites I highly recommend are three related sites, though they each require a separate membership. My favourite of this group is Assylum. The bondage is unique and the S+M is amazing. Assylum features anal sex and a lot of anal play if that interests you. It's updating regularly. https://www.assylum.com/
The other sites related to Assylum are Slave Mouth and Dom the Nation. Slave Mouth is a lot like Assylum though featuring oral sex only. It doesn't appear to be updating these days though there is a big back catalogue of scenes so it's still worth the membership. https://www.slavemouth.com/
The newest site in the Assylum family is Dom the Nation. This features outdoor (but not public) bondage, S+M and rough sex. It's updating regularly. https://domthenation.com/
I think I should rejoin some of these sites now!
