Chris plods along, not used to moving on hooves. His new cock was so hard, and his balls kept hitting his hind legs with every step he took. Closer and closer until he was right behind Linda. He snorted in the musty scent coming from Linda's ass and vagina.
She reacted to the hot air being blow on her sex. Linda mooed softly, and shifted her rear seductively at Chris. He couldn't wait any more, and jumped onto her back. Bovine instincts took control, and Chris quickly started jabbing his huge cock at Linda's swollen cow pussy.
It took a few tries to fine her slit, but Chris bellowed when his cock finally found its mark. Linda was too overcome to make any sound. Her udder swayed underneath her body as Chris began humping her. His balls slapped against the back of her udder and her legs. She could feel the thick head of his dick ramming against the walls of her vagina.
Chris' tongue was hanging out of his mouth, almost tasting the sex filled air. Linda's moist folds clung to his shaft. He couldn't believe how tight she was, even though her outer lips were so loose and bulbous. A tingle in his balls made him slow his humping briefly. Then, as the tingling stopped, he felt something rise up his shaft.
Bellowing all the while, Chris released his thick bull cum. The hot, sticky substance was shot into Linda's gaping cow slit. Much was sucked up by her hungry snatch. But more overflowed onto the floor. Chris carefully dismounted his heifer, and mooed.
Linda felt her lips clenching and unclenching over and over. She yearned to be filled up again. She looked at herself. Unlike Chris, who had become a complete bull, Linda was caught somewhere between cow and woman. She had a cow tail, an udder, and of course bovine private parts. But her hands and feet remained human, as did her head. And aside from the bush of black fur around her crotch, she didn't have any fur on her body.
"Is that it? Or am I going to become like you?" Linda whispered to her bull. HER bull. That was going to take some getting used to.
