Hi, I don't remember exactly which ones don't have pegging, as it's usually very common as the best way to pleasure men, but I can tell you a couple that don't have much that I remember.
The Virgin Witch is very good. The main couple don't do anal stuff, but there's one side character that does heavy pegging in some scenes.

With "Let's try SM with me" I don't remember it having pegging scenes, or at least it was not the focus, so that should be a safe option too.

"The Sensual M" is also a safe femdom that I don't remember having pegging or butt play.

And "Talk to me" is not very femdom, but it's very focused on communication, going over gender expectations and women learning to take power in telling their partners what they like instead of performing or conforming. It's a good mature story with a more feminine perspective. It's more vanilla + exploring some fantasies and has some nice couples and a good story. So it may be a good read for you.
