As Theia gently brushed her mares, she could feel the gaze of Yevgeny's stallion on her. Her nostrils flared, inhaling the stallion's virile musk. Like many Horse Witches, she had spent so much time in horse form that some of her horseness carried over into her human form. In this instance, she could smell just how attractive he was to mares. Except for the ones she was currently tending to. They seemed unaffected. Perhaps due to their pregnancies?
It finally became too much to bear. Theia put down the brush and went up to the stallion, tied to a post outside the stable. No royalists were in sight.
"I am Theia. What is your name?" Theia asked the stallion. He tossed his head.
"Thunder," he neighed. He sniffed her. "I was once a Horse Witch myself, you know. Vladimir Copperstone. But the horse life drew me in. I eventually decided I could no longer be human. I needed to be a horse forever." He sniffed Theia again. "In all my years, I have never smelled a mare as beguiling as you."
That was the breaking point. Theia shifted to her horse form and immediately presented herself to Thunder. Thunder accepted her invitation promptly. Theia whinnied happily as Thunder plunged his cock into her eager pussy. He rocked back and forth, his front legs on her back, shooting a never ending load of seed into her. Theia's eyes rolled to the back of her head in pleasure. Sex as a horse was something else!
After what felt like hours, Thunder dismounted. Theia nuzzled him, then went to run off some steam in horse form before returning. Hopefully, no one saw her. Thunder wasn't one of her charges, but it would still be seen as unprofessional for her to have done that.
