You felt nauseous, and the feeling only grew as your body was changing. Your skin turned purple starting at your feet, and slowly working up your body. Then felt like jerking, but it felt like something else was happening to you, and when you looked down you saw your dick was squirming, and shriveling up leaving behind a moist pussy.
