Heho,
This is for the fast sex dungeon.
I made a small edit to pack_dungeon\init\std\template\char\brain\code\run\basic_func_talk.dat. Now the women have clothed sex without any issues (as far as I've noticed). I have flagged the sections that were changed with 'CHANGED', so just search for that if you want to refine it. I didn't destroy the checks.
Of course, you'll need to unpack things first, as explained here:
click. Then you can simply unpack the .7z file attached and place it in the folder:
pack_dungeon\init\std\template\char\brain\code\run\
It's probably a good idea to make a backup of back basic_func_talk.dat first.
When running it, make sure you're using the correct story slot. One is the packed (unchanged) and the other the unpacked (changed). An easy way to distinguish the two is by editing story.txt in the root of the pack folder. You can for instance change the episode description for both characters (descr = "...).
