As he watched Kat's ears rapidly elongated and migrated to the top of her head, fine black hairs coating them as they grew, within moments they were unmistakably donkey ears, unsurprisingly she had been infected. "Yes!" Kat squealed excitedly as she felt her new ears up and down, "it's working, we have to keep going!". Wary of her over the top excitement Jay remembered her earlier comment about wanting to live on a farm, with a start he realized she wasn't just messing around, she wanted to go full donkey.
"Kat, we can't go further, you can't just decide to be a donkey, much less expect me to join you!" Jay exclaimed. "I need this Jay, I can't keep working at a dead end job, I want to be happy and carefree, I belong on a farm" Turning she gave Jay a clear view as her ass slowly expanded, a ropey tail beginning to poke its way out of the top of her jeans. "besides I know you love this..." Hooking her thumbs into her jeans she pulled them down and stepped free, her already sizeable rear continuing to grow, her thighs now having joined in.
"but..." Jay was lost for words as he Kat moaned and he saw her black panties darken with a squirt and her camel toe begin to slowly pulse and expand. "oooahhh, I need you Jay... please" As Kat pulled down her panties Jay was able to see what was happening, her vagina was darkening as it slowly expanded, a bestial scent filling the room. Throbbing in reponse Jay's cock unsheathed and rapidly grew to full mast, "oh shit this was really gonna happen" he thought, as he watched her tail grow to full length.
"What happened to you being a Lesbian" stammered Jay, "Forget that, I just want to be an animal" moaned Kat, unable to control herself anymore she rushed to Jay and pressed her rear against him, "just fuck me already!" No longer in full control Jay grabbed her hips and after a few prods found his mark, plunging into Kat's leathery folds. Bucking he began to fuck her, sealing both their fates.
