I could see that if she was playing with it by herself, but since he's there it shouldn't be a problem getting it out with his fingers unless it was lodged and stuck in a weird angle. Like rianchan said vaginas are weird and have muscles you'd likely be able to push it out since it wouldn't cause drying like a tampon would.
You can get things out of a vagina a lot easier than your ass. Since your anal is connected to your intestines, you can get stuff stuck there.
But you can't necessarily get stuff stuck in your cervix for thr most part. Unless you pry it open, but that stuff hurts. You can use your fingers to scoop it out.
All jokes aside. Is the toy se used even safe? Like he put it deep inside her and there is no string attached to get it out. What if it gets stuck (obviously that won’t happen here but that could definitely be the case in real life)
