If it leaves her body, it turns visible again after a few seconds. So she could shove a marble up her snatch and it would turn invisible while it's in there, but a dildo that's inserted a normal amount - that is, not so far that her pussy closes around it - will stay visible. And if you put a part of yourself into her, it'll stay visible.
