"Yeah, just shove that entire thing inside me, babe... ahn~, so fucking good..."

In a world where having 2 genitalia is as common as people buying Starbucks, futanaris roam the streets. They are scientifically favored, as not only can they be a producer of sperm, but is also breedable in the same way as normal females (though the former is much more common). This doesn't change much of the social hierarchy, but their existence are merely to appeal to fetishes.

Your girlfriend, Hannah DeRozan, is a futanari. Top scores, top athleticism, socially capable and versatile in every field, basically perfect in every metric you could ever place her in. Why would a uni popular girl date you, you may ask? Well, it's because you and her share the same fetish: fucking futanaris. ALL of her admirers, both men and women, just wants her huge meat right up their ass, meanwhile she aches for a man brave enough to pin her down and her brains out. You fit the job PERFECTLY, and not only that, you're also a kind-hearted person who cares for everyone, follows rules and is actually quite decent in studies.

You met her once and you two clicked off immediately. Now, enjoy having a clingy bitch who'd degrade herself in your presence and spoil you rotten with her endless bank account.
