Mary tried to sort out her thoughts, but her eyes kept getting drawn to Danny. Sitting there, working, his/her tight ass moving on the small chair. Mary had the sudden urge to go over and lick him from top to bottom. The thought of him suckling on her breasts, or even cock made her so horny.
"No, don't think like that. It's just the hormones. Cows have hormones don't they?" Mary asked herself. She continued her battle with her instincts. But it was a losing battle. Eventually she rose, and walked over to Danny.
"Hey, what''s up Mary?" he asked, looking up from his work.
"I... I, uh, need...." Mary couldn't bring herself to say it. But she needed to fuck.
"Oh, right hang on." Danny said. He went to a draw and came back with a vial. Mary thought for a second he was going to make her drink it. But then Danny popped the top off and drank it himself.
"The urges can be hard to deal with. Don't worry, we all have problems with it at first. Another side effect from the vials, makes everyone crazy horny. Can't even begin to tell you what my first week was like. The only thing I did was masturbate." Danny laughed as the changes took hold.
Mary stared in awe as Danny shed his clothes and started to transform. His sizable package grew out, and soon it was just like hers. Long, black, coated in wiry hairs and sweat. Danny's balls hung low on his body, which was gaining mass. His pecs gained definition, and his abs tightened. His arms bulked up, as did his legs. His feet burst from his shoes, and slowly morphed into hooves.
His legs cracked, changing to a digitigrade stance. Horns grew on his temples, and his face pushed out into a bovine snout. Fine dark brown hairs spread all over Danny's body, until he was a covered in fur. He tail sprung out from behind him. He lifted a hand, and the two watched as his fingers fused. They gained a thick layer of keratin, and soon he had hoof-hands just like Mary's.
When the transformation was completed, a new minotaur stood in front of Mary, ready to go.
"I can see why you picked this one. Something about this form gives me chills in the best way possible." Danny boomed in his new voice. It sent chills up Mary's spine. She couldn't hold herself back any longer. She went up to Danny, and then planted a big wet cow kiss on his snout.
"I guess you're good to go, huh girl?" Danny chuckled. In response, Mary's own bull cock rose and hit Danny's stomach. He wrapped his hand around Mary's shaft, and started pumping. She mooed, her penis becoming harder and harder with ever tug. She fumbled for Danny's shaft. When she found it, she lowered her snout onto it.
Danny mooed in pleasure as well, feeling his sensitive head butting against the roof of Mary's mouth. His tail whipped behind him, and he too couldn't hold himself back much longer. He yanked Mary up, and spun her around. He rammed his dick into her asshole, and she screamed as he started to pump in and out. Their balls collided against each others, making the sex even more intense, and animalistic. Danny feels like balls pull up, and then he cums.
Thick bull semen drips onto the barn floor, and Mary's own spunk is soon added to the pool. She fondles one of her large breasts as he orgasm finishes. But Danny isn't done. He latches his mouth onto one of Mary's teats, and starting sucking. Milk pours down his throat, and he's more than happy to drink it.
"Don't stop. Oh shit, don't ever fucking stop!" Mary moaned. Her hand drifted from her breasts to her bull cock. She relishes in the feeling of its soft pliable skin against her hard hooves. Her tail swats at the flies, and then, the deed is done. She and Danny both sum again.
Tired, they fall onto a pile of hay, wrapped in each other's furry arms.
