I hate to say this but as title, the animation progress is stagnating, in the last 5 days i spent all the time on the breast rubbing motion of the male model to Kronii, it should be a very easy thing but when the hand needs to follow her torse move front and back, his hands become hard to control

The hand is rubbing her breast with a circular path which is very usual way to do it and the best solution, i just need to make one loop and duplicate it then things will be done. But when his hand binding with her torse, the situation in the gif will happen. even though i set the same loop for the hand, the hand still move in different and weird way (you can see little moving path of the hand), i had try so hard to fix it but apparently i fail or otherwise today will be a progress update

Maybe i should change the breast rubbing into breast holding, just it will look a little boring, i will figure out how to solve the problem i believe but it will take some time,  i am so sorry about i got no progress in this 5 days
