Dialog to invite breastfeeding, but nothing happens - no animation

[Ascotfox]

I talk to an NPC and invite them to breastfeed, for example by picking these dialog choices:

 

"Were you just checking out my boobs?"

"Thank you! Yours seem pretty perky as well."

"Well... I certainly wouldn't mind giving them some attention if you'd like."

"I'm going to enjoy this..."

 

Then nothing happens. Either they stand there, they walk away, or they continue doing what they were doing.

 

I think I have all the dependencies installed correctly (through Nexus). I have a Papyrus log (would it help for me to upload it here?) and I see it say "MilkModEconomy 3J Breastfeeding animations found", and I don't see anything else particularly suspicious in it. What might I be missing? The dialog is supposed to result in an animation, right?
