You were about head downstairs to leave by the back door when you heard a car pulling up and you cursed as you remember your girlfriend Dawn was coming over to see you. You were about to leave by the window to the backyard when you felt a heat come over you and make your thoughts leave your mind as you looked around for a minute trying to remember what you were going to do. You heard your girlfriend come in the house as her scent came to your nose. When you smelled it you felt your body get hot and you thought of mating her and filling her womb with your cubs. With the house a ten minute drive from town no one would hear her call for help. You hid behind the door as you heard her call out to you can walked up the steps. When she entered the room you ponced on her and tore her clothes apart.
"What! Let me go!" Dawn yelled as she tried to get free. You aimed and thrusted you cock into her pussy which made her gaps! "AH!" You then started to fuck her slowly as you enjoyed the feeling of her pussy around you cock. Soon you were fucking her at a fair pace and you bit her on the neck. She tried to get free but you held her down as the changes started to happen to her. Fur started to grow as two sets of breasts formed below her first set which grew from a low c-cup to a high d-cup with her new breasts growing to the same size. A tail grew as her face became more feline. Her thoughts on the mating as changed as well. "AH! YES! TAKE ME!" She moaned as you went faster and harder and was hitting her womb. Suddenly you pulled your cock out to the tip of it and thrust back in hard you violated your mates womb. The feeling of it caused you to cummed into it as she cummed at the same time impregnating her with your cubs. You pulled out and looked at your mates new form. However you could tell that you wanted to mate and impregnate more females with your cubs and turn others as well. You laid on the bed with your mate and fell asleep planing look for more mates the next day.
