Phantasm: Dog: Caught1
From Create Your Own Story
You jump up onto the table and move toward her. You lunge, pushing her head back with your paws and jamming your cock into her wet, warm mouth. As you do however, she wakes and screams loudly. Suddenly through the door you came in, and forgot to close, rushes in another veterinarian. He comes in yelling. "What's going on?!" He sees you attacking her and runs up, grabbing you and pulling you away from the nurse. He puts you on the table and she grabs a syringe. They knock you unconscious, and wait for the other vets to arrive to decide on what to do with you.
You don't wake up.
