Silicone tentacles dildos longer than a man's arm bend and squish within. They do not rearrange guts, they enter guts and conform inside them, sillies. That's how the uwu bulging occurs.

The universal end we all have is easier to jam up seeds way up there. But the other orifice that not everyone has is possible too, if trickier. But stuff up past the vagina can accommodate a monster cock dildo with some difficulty pretty deep if the owner is so inclined. It is capable of rearranging itself to birth something about as big as the Hot Lobo XXXL anyways.

A hypothetical real monster PP with the same dimensions would work slightly differently in that it would both be somewhat more able to maintain baseline rigidity, and would also probably break PP long before it broke through a diaphragm.

Doctors are being silly and their hypothetical is not based on PP physics.

Maybe an object of the pictured size with far more stabbing power than horse futa cock would actually have, like a metal pole or something I dunno.

Yes you can fit those pretty far up too, coincidentally but those wouldn't break before they break you.

Also, use a flared base for deep insertions y'all.
