Hair of the Dog

Sly has a crush on his tall, beautiful coworker, a trans woman and fortune teller named Circe. When he finally gets her to come over, the sexual tension from work is tossed aside, as does his humanity. Circe may be careful with her saliva, but there's more than enough of her werewolf curse in her other bodily fluids and no one was ever supposed to be turned like this. 

Trigger Warnings: teratophilia, knotting, self rape/noncon, no lubricant, blood and gore, body horror, multiple orgasms, bestiality on a technicality
