It took a few minutes after Jennifer had finished milking her boyfriend Zach, now a were-Cowtaur, for Zach to snap out of what might have been a trance, might have been a careful brainstorm, might have been a small orgasm, or probably was a mixture of all of the above. By then Jennifer had already stowed the milk into the fridge.
Zach said, soothingly, "Sweetheart, transform or dare?"
Jennifer just about jumped with surprise after Zach's very quiet spell that those would be the first words out of his mouth. But turnabout was only fair, "Transform."
Zach smiled at her, looking strangely handsome on top of his bonny cow body, a small fire burning in his eyes. "For your transformation, my sweetheart, I want you to become my partner in this: a were-bulltauress. You should have full control of the transition between your usual sexy, sweet self and a bulltauress form with most of you unchanged above the waist. The exception will be a pair of beautiful bull horns to adorn your head, which you will keep even in your normal sexy human form."
Jen turned to stare at the new horns in the nearest mirror. Her hands moved to brush them. She had to admit that they did look pretty, the way her bangs played across them. The horns felt weird atop her head, but they also felt something different... The horns felt like power and lust and horniness. She rubbed them a bit stronger and slowly felt an erection creeping its way out of her...
She gasped and finally glanced down to the sheath that had crawled up the curve of her abdomen. Zach's eyes were transfixed on it, "Feels weird, huh?" Jennifer then became aware that not only were Zach's eyes intently watching her crotch, but that Zach's cow tail was almost standing straight up and a certain, pungent but indescribably arousing aroma was filling that room. "What is that wonderful smell?" Jennifer asked.
Zach shrugged, "What smell?"
Jennifer's only answer was that the rest of her quickly flowed into a full Bulltauress. She licked lips, bowed her head to take a deep breath of that scent that filled her head with erections and then stormed after Zach...
Zach wasn't quite prepared for his girlfriend's charge and it was a short chase. Zach moaned, in a way that Jennifer didn't think she had ever heard from her quarterback boyfriend, as Jennifer instinctively and aggressively mounted Zach.
Jennifer wasn't quite sure if she heard it right, but at some point she swore she heard Zach contentedly sigh, in between deep moans, "Best. Costumes. Ever."
