The lady whistled for Billy and appeared he did in all his goat glory. "Greetings, milady, I am Billy," Billy said as he seemingly stretched. (He was actually, bowing.) The lady marveled at the beast before her. She sunk to her knees and pet his head.
"You can talk?" She asked.
"Yes, I did not lose my way of speech," Billy answered her.
"Incredible. You must come to the Queen's Court. She must see you, this is indeed quite rare," the lady said and continued admiring him. She bent down to get a better look at his package, his penis was already out and long and she touched it lightly. "It's magnificent!" She exclaimed.
"Thank you," Billy moaned lightly to the lady's touch.
She instantly stood and wiped her fingers in the dirt to clean them off. She turned to see John still standing by the latched gate and was about to call to him when she noticed his smile. She walked five feet from Billy before she was attacked. Butting her from behind, she fell over on her hands and knees, her dress raised far above her head.
"NO! What are you doing, beast!" The lady demanded as she began to get up to retaliate. But Billy had already leaned his weight on to the poor girl, trapping her on the ground where she was. Unfortunately for her, she wore no undergarments to protect her womanly nether-lips, and Billy's stiff cock penetrated her quite easily.
She moaned in surprised. "No! Stop!" She cried as the beast began to rape her beautiful thin lips. They parted suddenly and quivered at the beasts entrance. Billy gave her no time to accommodate to his size and pumped into her relentlessly. She moaned more in pleasure, she gripped the grass underneath her with her palms as she rolled her shoulders from the pain of it all. She rose her head and tried to knock the beast off but failed. She screamed in defeat but her voice cracked. A bray escaped from her darkening lips as she began to enjoy the beast.
Billy continued to fuck her as her new tail emerged from above her but. She brayed again. "Baa aaa Jaaaa -ohn... " She cried, reaching a hand toward the grinning farmer who laughed. She nearly lost her balance and resumed her stance on hands and knees. She began to cry lightly as her body began to succumb. Billy's pumping grew unsteady and he quickly spurted his seed deep within her vagina. He pulled himself off of her and stepped back.
The lady scrambled to her feet quickly, only to find her self falling face first to the ground. She groaned in pain and rolled her body in the dirt. Her body was being overwhelmed by intense heat as she began to desire more pleasure. Her lust grew in her mind and she ripped the top of her dress down to expose her C-cup breasts. She messaged them eagerly, she felt them tingle, and she raised her head to see why. They had apparently turned black to suit her future body and she let her head fall violently to the ground. Her eyes looked up to the sky to search for the answer as she rubbed her nipples absent minded. She closed her eyes suddenly as she felt a rush of pleasure and desire run through her body. A hand slipped down to her groin, and she began to rub it enthusiastically. Only, her dress was in the way.
She then screamed and rose to her knees and faced Farmer John who was enjoying the view. She brayed again with wicked eyes fueled with hatred and though she could not make herself to rise and attack the farmer, she could use her strength to rip her dress off, which she did.
Billy pressed himself against her body and she turned her attention to him. She quickly saw his penis growing hard again and she jumped quickly to it. She placed her lips on his penis and began sucking like there was no tomorrow. Two little horns sprouted on the top of her head as she continued her change. Her hands were now clenched and darkening as she continued to suck. Her hands eventually formed hooves and her feet followed suit. Her shoes popped off her lengthening feet as they grew. Her lower leg shortened as her ankles rose off the ground. Light fur began to slowly grow along her belly as she felt her stomach become sensitive in certain areas.
"Another one joins the herd," John chuckled.
You sat in your barn, chewing your hey and felt your dick become hard again at the sight of the girl's change.
