Good progress, but I see some issues are STIL present:
- arousal upgrade increases your lust gain, instead of partners? Shouldn't it be reverse?
-In fact, the whole sex skills tree could use a re-work. Perhpas individual skill upgrades (oral, vaginal, penetration, etc..), fertility/verility
- player fertiltiy being 100% is not great at all.
- option when talking to a girl the player impregnated - give her 500bn and send her to the hospital to get their baby in the tank
- proper lesbian animations - 69, scissoring.
- penis model (on futas) isn't that good. It doesn't fully connenct in many poses, especially if you make the character smaller. Furthermore, since you're using IK on the tip of the penis with a vagina target, it tends to stretch the penis A LOT. Even worse with smaller character.
Possible solution - reduce weight. Set it lower in the animation at point the vagina is furtherest away. Another fix is to adjust the root position (can be done programatically, based on character height) of the smaller character up/down a little during specific animations. For example, the coch handjob, a small character phases partway into the couch, so move it up a little.
