I Need Assistance Coming Up with Ideas

So my girlfriend and I have this unspoken arrangement where I get her nudes and I send her basically erotica, but I can only write the same stuff so many ways. I am blanking on new ideas or combination of ideas to send her because I don’t want to be boring and I want to hold up my end of the bargain.

She is into: degradation, rope play, exibitionism, she is a brat, being dominated, masochism and light sexual torture. If you can suggest for me to look into new things to bring up or include that would be great!

Sorry if this post doesn’t really belong here, if you know where it does belong can you point me in its direction?
