You look down and your hands and you get a massive shock. You have huge wings flowing down from your shoulders. They're a dull golden brown, like a golden eagle, and they've completely replaced your arms and hands. Your torso still looks human, with large pecs and a six-pack of abs and as far as you can tell, your back looks great too. But below that, while you are wearing swim trunks, you have a tail fanning out behind you and below the trunks, you have scaly legs and large avian feet. You can still see your nose, kind of, so you think your head still looks human.
The vampire who waved you over smiled, showing off his fangs, when you got up to him, stumbling a bit on your unfamiliar legs. "Hey there, I didn't see you get on the beach earlier," he said, "We need a referee, and a harpy would be great at that. It'd be great if you could fly up there and keep an eye on us."
You're in shock from everything that's happened so far, so you just nodded and awkwardly spread your wings and experimentally flapped them as hard as you can. You shot up into into the air and almost instinctively knew what to do to stay up.
The man smiled again. "After the game, come talk to me! I'll do you a very *special* favor." He winked, and you blushed. But you quickly forgot because it turned out? Flying was the most incredible feeling you had ever had. And while you *tried* to referee the game, you were more focused on the amazing feeling of diving and dancing with the wind.
