Very great insert this is really a must have, there are times when the fingers are always drawn out because of collisions and this is perfectly self adjustable and amazing. May I ask you the same way you have the possibility to make mouth and lip inserts? I find that the mouth and lips of the character often pull out and distort when they hit a large sized penis or a hard object, etc.
