You might be too young or new to this, but ten years ago, commissioning a good cuckold story—especially one with Latino or Black elements—was expensive. And that was just for text. If you were a broke teen, you had to rely on generous forum users....but it's just ridiculous funding a passion project for months or years, to the tune of 5-10 bucks a month, and spending what you'd spend more on a short game than what you would on a triple A title.
That was my experience, anyway. Netorare stories are much more common now, but I don't think they'll become mainstream anytime soon.
