Paid Scenes In the Tent

I have a question. I deleted the key frames of hand grabbing in Time, and then replaced them with the key frames of hand grabbing that I added. But I can't make the hand grabbing action. I am sure I did it right, because my character has a big chest. I often replace the characters in the scene, including the hand movements. I will remake them, but I have a problem with your scene. I would like to ask if you have any plug-in to control the male hand movements? ? Generally, I don't encounter this kind of problem.

Looking amazing, details is dope
