Study It

You find yourself curious about what this cow is and how it works. You've been a veterinarian for years and have never seen anything like it. You parked your truck nearby when you started your walk and you should have a pair of long gloves inside. You hurry over to it and make sure you're not spotted by the wolf from earlier. You reach the truck and pull out a pair of gloves and rush back, to your relief the cow is still there. You slide the long gloves on and slip your hand up it's rear to study it. The cow is luckily unphased by this, leaving you to study the creature without it rearing up and kicking you. But examining the animal this way has told you nothing besides the sounds of your gloves squeaking against the rubber insides of the cow, everything is normal.

Suddenly you feel the cow tighten up. You try to retract your arm but it's stuck. You feel a hot liquid fill the inside of the cow. You keep pulling, but you have no luck as the liquid melts your gloves and burns your skin. You scream in pain but no one is around to hear you. Pressure builds up forcing your arm out and knocking you onto the ground as it suddenly gives way. But you look up the thick brown liquid continues to pour out. You try to get up but it has a mind of its own and latches onto you, climbing up your body, engulfing you in the brown molten liquid.

You pass out from the pain.

Hours later you wake up disoriented with the cow standing over you. You get up and look down. Your now completely naked, extremely muscular and have a massive cock. Your skin has also been transformed into latex the same deep brown colour as the liquid. You touch your face, it's no longer a human face. You spot a nearby puddle and rush over to it and look down.

What stares back is not the head of a human, but the head of a bull, a latex anthro bull.
