Wonderful, thanks! I think the scale of the doll may be off a bit, but it still shows how amazingly deep a big cock can go in a girl who can open up the space past the cervix.
That makes me think of an interesting question - what happens with a woman who's had a hysterectomy? Does she still have a cervix, and does removing the womb make more room in the abdomen to take big cocks - and maybe explain some of the porn actresses who can take the really huge ones? I've heard that women in sex work and porn are more likely to have been victims of sexual abuse when young, and that in turn is associated with higher rates of "female troubles" that doctors try to fix with surgery, removing ovaries and uteruses, and you can see the scars from operations like that in a lot of pictures (at least something the female eye picks up).
