Isaac was watching two werewolves fuck.
Seth had gone away somewhere about an hour ago, so Isaac had come to the werewolf village in the north and just kind of watched the werewolves like a creeper for a while, and then suddenly these two had gone from joking and talking and pushing each other to fucking in the snow. The guy on top was Isaac’s age at best and the guy on his hands and knees was a few years younger. Their other friends didn’t seem to care, the people walking around the village didn’t seem to care, everyone could see them. They seemed to be having fun.
As the boy on top was getting close to cumming—the signs were obvious even if he wasn’t human—he picked up speed, fucking his friend wicked hard and then harder still as he…got bigger. And grew fur, his face changing into a muzzle. He didn’t turn into a wolf, not all the way, seeming to stop halfway through the transformation. Even his dick had changed, Isaac saw in the brief flashes where it wasn’t totally buried in his friend, getting longer and thicker and redder like a dog’s, and…
“Oh, fuck,” Isaac said aloud, leaning in to get a better look as, just like a dog, werewolf boy’s knot emerged, and then was pushed right into his friend, keeping him there.
Isaac had forgotten to masturbate during the transformation, but he remembered now, furiously stroking himself until he shook the Web with an orgasm unlike anything he’d ever pretended to feel. “Fuck,” he said, sitting back and watching them, stuck together now. “I’d have made such a good werewolf.”
