I hate to be the guy who just comes by and complains, I really do, but you have to add some kind of auto release. I am completely softlocked in Lamia.
I have T-4.5,V-5.7 and have been stuck since day 12. It's day 34. It takes all 8 stamina to get her head into the second stomach most of the time meaning multiple attempts to even try getting out and by that point, amelia is either from 0->9 lust or is exhausted and demands sleep both of which lead directly to lamia waking up and right back down I go. I am at the point of assuming that being eaten by lamia is a game loss condition as the only option to get out is to reload an earlier save.
I learned from last time and upped my stats before trying to take this one (and coming here to complain) and it has made no difference.
The new pictures are nice though. Keep up the good work.
