First of all I think NRX direction is very aesthetically pleasing, however the better oral sex parts could still improve the final product. Point 1) Ass to mouth sequences seem to happen (if happen) behind the camera (There seems to be never a shot where we see it in same frame). Ass to other girls mouth is also very welcomed act. Point 2) There aren't much facefucking/deepthroating in the scenes. Point 3) Lack of asslicking/rimming/gape licking.
For inspiration i recommend to revisit one of the best ATM video in LP ever:
