Yes and, are we supposed to believe in a game with an mc with a cock that big, a transsexual dog, and didn't they dev say you will be able to get all of not most of the females pregnant including women who are far too old to get pregnant, realism is suddenly supposed to me something in this game.
No offence dev.
1. Cock thing, yah typical male fantasy.
2. Molly our Transexual Dog, is really just a female dog(The gag being
MoonBox used wrong dog for a scene or two)
3. Far to old to get pregnant, you don't understand how the real world works do you?
The oldest known woman to get preggo and give birth was 74-75 range. Youngest was 5(Gross, but that's documented). I believe she had twins also.(The older one). There been reports, but undocumented of woman as old as late 80s giving birth.
So beyond the Penis thing, the accident of an asset, all this is still in the realm of true. Before you say but all these woman on his dick ain't real. Might I point out to you through history there have been very high charisma humans who have done this. Be it through Royalty, Religion, Politics, Power, etc..
Now for your comment about Anal vs Vaginal ease. LOL, again that's biology, no it's not easier. Anus does twist and turn the intestines that twist and turn to fit all that in compact wise. Then Stomach, Esophagus, not to mention stomach acid, lol. While yes stretching is possible, anus can do that, was never ment to do that, while vagina was ment to do that do giving birth to a Football or bigger, lol.
I know your probably just using hyperbole, but come on now. This story can still be someone realistic, for pete's sake largest penis in the world came out to 13.5 Inches with a 8 inch diameter. So, yah
EDIT: The hypothesis of Priya making a fertile drug out of our semen(to effect even infertile woman), well that could go in realm of fantasy, but I'm sure there have been actual science work on such topics, etc..
