Jake was so surprised that he was helpless to stop the witch forcing her potion down his throat. It tasted like a very salty chicken broth with a lot of egg yolk. He was confused at first. Had the witch merely fed him soup? But the magic soon went to work and he screamed in pain and fright as his body changed. His armpit hair fell in great clumps and the hair on his arms did the same. As he looked with panic into his trousers, he saw that his pubic hair had followed the same way. He then saw his skin on his legs become tougher and bumpy. He touched it apprehensively but came to realise quickly that the bumps were not warts or dry skin but scales. His bones then snapped painfully into new shapes. First his ankles curved backwards and his toes grew to freakish proportions, his toenails becoming frightful claws. No, not claws. Talons. Then his arm bones elongated freakishly, especially one digit. His arms resembled ugly pink sticks. Then, like crawling like insects, out of his empty hair follicles sprouted feathers, even fusing with his scalp hair, creating a strangle mingling of organic material. Feathers replaced his body hair, tawny brown and plentiful. Jake could only squawk in fright. Screech as his vocal cords shifted. Worse, his insides, as the finishing touch, were in turmoil. After all, Jake was to become a male harpy and not a duck. Unbeknownst to him, only dicks have penises, and huge and spiky ones at that. The other bird species don't have penises. They havre a cloaca, a single tube for dejection, urine and reproduction. As Jake remained male, his cloaca would have to be rubbed against that of a female. Appalled, he shouted his horror as his virile member treated with his testicles into his body, his penis turning itself inside out to fuse with his urethra doing the same and both merging with his intestines, creating the sole tube for the three functions. Jake could feel them shift and settle in his body, to stay still forever. Never again would he masturbate holding his large penis or feel his balls swinging happily. He'd be reduced to rubbing himself clumsily, like a girl, as he thought in his misogynic mind. The only virile attributes he had gained were impressive abs, a large chest, and a more chiselled face. As the transformation slowed and halted, Jake was left in his new harpy form, while the witch looked on with pride at her work.
