Adding more ass to mouth would be so easy

I like ass to mouth and there's very little of it shown, even though there's plenty of opportunities for it. Guys are often switching between ass and mouth, it just needs to be shown. Mostly the opportunities are missed:
It would take very little to add a lot!
- Guys switching from ass to mouth, but walking around behind the camera
- The switch is shown, but the guy strokes his dick for a couple seconds before letting her suck it
It would take very little to add a lot!
