lick

The tongue seems like it has a lot of untapped potential. I would like to request a mod to add different motions for the tongue that can be hotkeyed. I would like to be able to make her tongue circle the tip when it is close/just inside the mouth, so the tongue can be seen whipping upwards but...

are there any mods like this? i want a manual button for licking. every-time i press it, she'll lick the penis of him/her.
