Garret knelt in the tall grass, panting heavily. His black shirt was torn open, revealing his heaving chest. A trimmed beard framed his contorted face as waves of pleasure wracked his body.
The werewolf loomed over him, a massive figure of brown fur and rippling muscles. Its red eyes gleamed with hunger and lust. The beast's long cock jutted out, dripping with precum.
"Please..." Garret begged, though he wasn't sure what he was asking for - more torment or release. The werewolf grabbed his shoulder in a vice-like grip, pinning him down.
With a roar, the creature hilted itself inside Garret's tight hole. The man howled at the sudden intrusion stretching him open. Hot cum flooded his insides as the werewolf pumped into him.
Garret felt something shift deep within him, bones cracking and reshaping. Fur erupted over his skin as he changed. His cock grew longer, thicker, turning into a wolf's knot.
He came explosively, jets of semen splattering the ground. The transformation consumed him, completing its process. Garret was now a werewolf too - a beast like the one that had fucked him into this new form.
The two creatures panted together in the moonlight before mounting each other again, insatiable. They rutted wildly as more howls rent the night air under the cloudy sky.
