Demons tend not to invade the surface much these days; not worth the trouble of being attacked by Demon hunters. So why did Xorkerran take the risk anyway and pop up on the surface? Merely to find a suitable mate for him, if he exists with the humans. But until he can find him, why not have some fun with the local talent? And why not build them up just the way he likes them? A little whiff of his essence, and BOOM! All of those guys now sport big and buff muscles, with less intelligence, and an unending lust for the male flesh, starting up orgies everywhere he went. It wasn't supposed to be destructive, but as more men are corrupted by Xor's scent, he grows stronger, soon accidentally starting something even he can't stop. But by then, would he truly want it to stop? This story contains gay male content, including eproctophilia (fart fetishism). It is intended for a mature audience of 18+ years old.
