I just tried moving the other animations for masturbation out, and yeah after the AS animation my character strikes a T pose. I wonder though:
I seem to remember Adult Show's "laying" masturbation animation had an actual part on the animation where your character would fluidly move down to her knees and on her back to start masturbating, striking a pose similar to the current AP masturbation. If you have this animation, could you check that out? because if it does, it would probably be better to either have the 2 animations, one playing after each other throughout the phases, and end with the regular AP animations; you would have to play a bit with stage timers but it wouldn't be much of an issue, just enough to make sure the laying masturbation animation doesn't finish completely, otherwise your character would also animate standing up... Or simply use the laying animation itself? It wouldn't be "standing" of course, but as I seem to recall it, your character/NPC would at least animate as they get to the ground, and it would be a far more fluid transition between standing around and start masturbating.
EDIT: I just tried it, and indeed works Adult Show's masturbation animation Standing as the first AP animation, then Adult Show's Laying animation as the second, and then that's a better transition from laying to laying animations. Only problem now is it's a bit lack-luster to go from Adult show's animation to AP
Also my stage timers for consensual animations are as follows:
The second stage, the one that is now playing the Adult Show's laying masturbation animation lasts 25 seconds. However since the laying masturbation starts a little slow (as in your character takes her time to get her hand down between her legs) and it seems less than 25 sadly. So maybe this is where I said the stage timers would still need a little bit of tweaking, but still not nearly as harsh as to mess up with all the other consensual animations.
I think both masturbation animations are set to last around 60 seconds each (Adult Show's), so maybe increase the first and second stage timers a little and decrease the rest of the stages, as the rest in all other consensual animations are mainly transitions from nice smooth sex speed to downright bunny-mating. Then again, that's up for personal preference. just giving my thoughts away.
Thanks again for the original idea
