Foot kink

So… I don’t know if I can ask this here, but that’s the question: I’ve a FWB and we really enjoy our sex intercourses together, recently she confessed me she’s a foot kink (I am not surprised, she always loved to kiss and massage my feet). I’d love to give her a nice footjob (she’s a trans female like me). So I was wondering, there’s anything I could read/watch to improve my skills? Right now I’m training with my dildo… 🤭
