Jon turns towards Sarah, she now appears to be entirely quadrupedal but there are other differences , a stubby tail has begun to form at the base of her spine and a swelling on her belly has begun.
"What's wrong Sarah" he asks
Her only response is whimpers as she holds up her hand, her fingernails have grown thicker and her fingers are starting to merge.
The fox -woman smiles as she leaves, making notes.
"Wait!, what's happening to her? Why are you doing this?" Jon cries out but his pleas are ignored.
Sarah meanwhile is sobbing, Jon, feeling compassion for her goes over to comfort her, as he does so she gradually grows calmer.
If you were to ask him later he wouldn't be able to tell you why he did it, somehow, almost as if it was the most natural thing he and Sarah were kissing, as passions burned out of control Jon got behind her and penetrated her , they began fucking like wild animals, and unaware of it as it happened both began to change. Sarah developed a tail, her face pushed out into a muzzle and large nostrils , large ears not unlike a cow or some other ungulate formed from her human ears and blonde fur formed over her body, her hands and feet became hooves, her beautiful blonde hair became an equine mane and an udder formed under her belly, as she grew larger and transformed into a strange beast, part horse and part cow Jon's transformation was no less strange except for it being in the opposite direction.
AS Sarah gained fur on her body, Jon's body hair evaporated, his hips widened, his legs took on the toned appearance of a trained female gymnast or cheerleader, a light tan spread across his now smooth, blemish free skin, as his feet and hands became dainty with perfect manicure or pedicures his waist and shoulders narrowed. As moans of passion became bestial lowing from Sarah the timbre of Jon's raised in register becoming the sexy moans of a teenage girl in the throes of passion, as his throat lost it's Adam's Apple and became swan-like and slender his voice took on the tone and pitch of Sarah's former dulcet voice. Jon's eyes shift from Hazel to aquamarine, the eyelashes grow longer and fuller, the lips from which that sexy voice was issuing forth girlish moans plumped and took on the contours of a teen Princess, even as his other facial features shifted until Gibson became a MacMillan, perfect, straight white teeth, chiselled cheeks and jaw line, nose small and aristocratic as Jon's hair shifted from short and brown to long and full and blonde his nipple grew and the flesh behind them began to expand, after an unknown period of time The original Sarah was a strange beast being passionately fucked by a she-male in the likeness of her original human form, soon even that changed as the male genitals of the new Sarah transformed into a perfect copy of Sarah's human pussy.
New Sarah collapsed, spent from her peculiar passions, she barely resisted as one of the Horsemen walked in and began wildly fucking Beast Sarah, New Sarah wasn't sure but it looked like he too was transforming into a human form, she passed out.
