You are a human male. You have a nice and loving boyfriend. You don't know it, but he is a harpy, disguised as a human. Harpies go to human settlements to look for mates and partners. Harpies kidnap humans and keep them in their flocks whenever they like it or not. You of course have no idea he is a harpy since he is good at disguising himself. Right now, you are perched on his lap watching a movie with him nuzzeling into your neck. It's his 18th. Birthday soon and he has decided to take you back to his flock to mate you. But for now, he is trying to make sure the transition will be easier for you and you won't hate him.
