You cant control yourself. YOu begin to really go to work on the dog remember your first blow job. THe dog begins to pant lick you harder. Before you know it your sucking on the creatures emerging red shaft like it was the nectar of life and you were a dying babe. Then the dog starts licking you back and accidently nibbles on you.
You are immediently pulled back to reality.
YOu try and stop yourself. Pull out of it or somthing but you cant. Your mind is racing trying to figure somthing out to stop it. THen you think about the when your brother kicked you in the balls and how bad it felt. for a moment it worked. YOu manage to stand up and get away from the dog. YOur mouth is dripping with the dogs precum. THe dog just stays there lying on its back looking at you like "hey come back you aint done!" Your skin itces viiolently and your back almost brakes in half as you feel your skeleton reform. looking down you see that clothes have all disappeared. Fur starts to spread all across your body and the your penis begins to shrink. But as quickly as it started it stops. YOur standing there half covered in fur and with a dogs dick half the size of your normal one.
