All right. So went back and tried double checking those:
For Nue, that was M/M, Top, then have him suck you. The next level of the menu never comes up so you’re unable to interact further, can’t even cancel out.
For the female devout. Your assumption is correct, that’s M/F. I was able to reproduce here with the initial devout (I chose the pink haired woman). Go through foreplay, then Oral -> Be Gentle -> Encourage Her took me back to the anal menu. Tried a couple more times with Gwynnifer and Bird Girl, but didn’t seem to happen. Also seemed to happen only the first time I tried.
A new one I noticed is it seems I was unable to prematurely end the encounter. Kept getting prompts which I think are responses to “Go down on her”
