Remembering how nice it felt when your own penis slid into the dog sheath, you bark once when she mentions the Breeding Pens. She smiles as sheopenes the door. "I rather expected that - it's the most popular second stop for most of our males."
You trot happily behind her, tail wagging and tongue lolling out. Being a German Shepherd feels - well, it feels good, but in truth, you just feel very normal. Before you can really think much about that, the woman opens another door, and new scents snag your attention.
"Here we go, boy." She leads you to a pen where a German Shepherd bitch is sitting. The dog leaps up when the two of you approach, her tail wagging and eyes bright. The woman guides you inside through a gate, which she closes behind you. "Maria here is in heat - I am sure the two of you will have a wonderful time."
Then she turns to leave, but stops and looks at you. "I should warn you that having sex often locks a costume into reality - there's a good chance you'll be stuck as a dog for the rest of your life if you mount her." Then she leaves.
You blink, torn between the rising desire of your canine instincts and the fear of becoming an animal for good. The female isn;t helping you, either, rubbing against you and whining. Her need is very strong in your nostrils, and you can feel your new doggie penis pushing out, pink and slick.
