Third scene opens if you have more than 11 lust. Like 12+You need to watch the second scene with 12+ lust then third scene unlocks.
thanks for the answer. Apparently, I had to progress a bit more in some other quests somehow? I already had the lust at 21 but couldn't get the third version after doing some other quests
That should be it. The only requirement is 12+ lust.You can fix it by using console in cheats. Enter:
trainLVL.set("Ino.boobstouch", 2)
Then "exit" to close console
Alright, I'll keep that in mind for my next playthrough!
