She has some tearing 😢

Mineral oil applied before melt may help the resculpt.

Just starting to learn/practice this mod.

Hi not an expert but I am learning as well seen this is quite common, looks? again guessing like a job for a solder gun with narrow tip removed, but I don't want to give bad advice, glue will crystalize kinda firm, not pleasant. Don't want t he solder gun too hot, a gentler melt is to remove plastic around a hot glue gun tip and melt with no glue

sticks just holding a sculpting with heat, you don't even need to squeeze the handle.

I redid 2 different models and and was quite surprised they had no waterprooof ball inside, so I installed a rubber paddle ball inside and vagina front ends. It is easy however to accidentally make new smoke stains that are dificult to remove and you don't want to go into too far with iron etc, as not to change curve texture etc in cavity/canal.

Not to be smart about it but if you were making love and used that hole that could have caused it. If you haven't then maybe stretching the legs too far apart? Jenny and I don't do anal and I am super cautious about how far apart we stretch her during play time.
