Someone once told me: "You bastard don't you dare bring logic into porn!"
But hey mistakes were made, and Mr Author here has brought up numbers, that's right people numbers! So lets math:
3 inches is y 7 cm, 8.5 inches is 21 cm...
To put things on perspective, that cone is at least 10 cm tall or so, and it has a max diameter of 21 cm.
That means that her anal gape, if it retained original proportions, has a circumference of aprox 32 cm.
No human penis will ever satisfy her big, big, obscenely big gaped hole.
So by mere math we can know that 3 meat balls each 2 inches big (that's 5 centimeters), will do nothing to her, nothing, even when put on an horizontal line one after the other that gives us a measly 15 cm, she would need 2 meat balls each 15-20 centimeters big, and meat balls are just that, meat balls, so they will get squished and comprised losing size, so in reality to really feel it she would need some 35 cm big meat balls, those are some unrealistically big meat balls, thus option B can. not. be.
Lets evaluate option A, Pouring cream on her gaping ass, her 21 cm gaping ass, of a 32 cm circumference, we could do some math here and find how much cream she would need to fill herself, we could, but is not worth it, that cream will just block what is by now clearly an unbelievable sight, plus what would some cream do to her anyways? cool her down after all that friction? boring.
So by discard, we are left with option C, a prolapse, and she better have to be prolapsed after all that was happening here, the only way for her anus to retain some decent proportions is if her rectum had come out of her body in order to save the shape of what once was her ass, that's right, her body upon withstanding the heavy abuse did what it could and dragged her insides out.
As we know the rectum is an amorphic zigzagging tube that leads into the anus, which is the final orifice on the digestive system, but that tube is no more, after its base was stretched in such an irresponsible manner, what was once a tube is now a conic tube that's trying to compensate the stretching to keep things pseudo functional, it will look as if she is starting to shit her intestines out, and what looks like the tip of that organ which is coming out of her, is anatomically somewhere around the mid of her rectum, the mid of her rectum is now not only outside of her, it is also acting as her new temporal anus.
So i guess we are left with option C, because it's the only one that makes sense, and the only option that could actually make her feel something, since we have come to these extremes it would be nice to see how her body passes from that nonsensical 21 cm wide gaped asshole, into what will be a prolapsed anus trying to retain her now gone shape, as her swollen blood-vessels try their hardest to retain a structure.
