You tackle the old man, not caring about his age, growling intensely. "Hey!" He yelled. He's on the ground, on his back, and swiftly, you bite his dick. He screams in pain and you notice that a change is going over him too. Brown fur sprouted from every pore, his white hair turning into brown. You notice that you're gaining mobility as well, your paws are changing into legs. Soon, you are both anthro deer. Panting, you notice that he is now moaning. He was a seven foot tall stag, and you are a 6' 7" doe. Then, you notice that you are regaining your cock and growing antlers. You grow to above his height, and he gulps. "Scared now?" You say, in a deeper voice than you'd ever thought you could manage.
