Is there any current way in the free version that you can unlock the blowjob skill or is it still in the SubscribeStar version? If it's available from the 0.41 prototype, how do I go about unlocking it?
It's unlockable in the current version, you just need to get your Indecency high enough -- unfortunately that version has a bug, which makes leveling Indecency slower than it should be.
That leveling bug is fixed in the next build though.
