Devoured by the beast (klance)

One morning Lance returns home from partying and stumbles across an unconscious and naked man. He takes him home and bandages him up. After a few hours he wakes up with a hangover and discovers that the stranger is gone.

A month later Lance gets up early because he can't sleep anymore and discovers the same man in the back of his garden. Again naked and unconscious. He takes him home again but this time he stays by his side and after the man rouses from sleep Lance is able to demand answers.

After that Keith comes every morning after the full moon. Until one evening he texts Lance that he'll stop coming. Lance takes it upon himself to find him in the forest. There for the first time he sees him turn into a werewolf.

"Lance swallows down the fear and takes a peek over his shoulder to get a look at the beast's crotch. And holy motherfuckin' that dick is HUGE. Long and thick, hairless and, oh boy, is it dripping with precum. Big drops of white spill down the length and slosh onto his backside.
And Lance isn't that naive to not understand what the beast intends to do."
