If you know it's a fantasy, and you're content to leave it there, then hey, de gustibus non disputandum est, amiright?
For instance, I kinda enjoy imagining that I'm the captive of a jaguar warrior, who gets unfailing advice for his battles, from the gods…which he gets, by topping his oracle (me) into semi-consciousness, whereupon I start blurting out stuff that makes no sense to me, but that he understands. And since I'm his personal connection to the gods, they have to know it's really him before they speak, ergo, he has to cum inside me.
There's a whole lot of historically inaccurate stuff in there. The Aztecs would just as soon sacrifice a captive, than keep them around for that sort of thing; and depending on the location, gay sex would have been a huge no-no, arguably for their elite warriors, and DEFINITELY for commoners. As for joy juice being the nectar of the gods, that's closer to a Viking idea than anything Pre-Columbian. And eroto-comatose lucidity would probably have been an unknown concept at the time, anywhere.
So, yeah, I get it: that kind of scenario is not realistic, and it's not even close.
Still, try telling me THIS dude isn't easy on the eyes…
