Fics like Faulty Vampire meets Stud Orc!

Riley is a vampire, a very unlucky vampire. You see, the poor guy was born with a special condition that only let's him feed on semen. You can imagine his frustration when his figure evolved into a nice pair of thighs and a thick booty, not at all helping him with his medical condition. Now, mix this unique situation with a world where magic isn't just real, but permeates every single place on this planet? Yeah, he's not staying pure for long enough... Today was one of those days where he found himself hungry and with no prey on sight. Stumbling across the woods in a hungry daze was never a good idea, but coming across a male orc whom thought he was a girl? That's one hell of a way of feeding himself.
