I bought it from a reputable sex doll supplier, and I don't think I did anything that could have caused excessive damage or stress to that leg; I was just unlucky.

It looks like it's been applied in layers. I received these the night before. It appears to be near her breasts. As mentioned before, just dab a small amount with a toothpick. Don't forget to apply acetone to the area first, otherwise the added silicone won't adhere to the big breasted sex doll.
