You suddenly ejaculate, releasing you human sperm as you feel a churning in your testes. Your balls were now full with a bear's hearty semen. Your penis becomes long and pointed. A sheath grows and attaches your penis to your belly. You were now completely covered in fur. Your face pushed out, causing excruciating pain as your eyes became blackened and your nose became moist and leathery. Your ears became rounded, yet still pointy.
Your back snaps, as you become a quadriped. Your legs become more suited to hunting and you grew claws. To finish everything off, you grow a short tail.
You try to scream for help, but all that came out was a roar. This was your fate. You may as well accept it.
