Quick and exceptionally nimble, Jennifer ran from the farmhouse to the barn, she darting inside the 15x15' box stall where her donkey colt lover stood smelling her scent as he hung his cock in a full erect state.
Jen crouched low when she heard the voice of her father and brother coming to the barn. Her luck was with her still, as dad wanted to show his son the new farm tractor and what it came with as attachments.
"Oh wow," Jen got out of her still growing muzzle.
She watched as waited for her dad and brother to enter the farmhouse before she felt at ease.
Jen sighed, as then she felt something lightly touch her lower back. Though her back as butt, and most all of her skin was covered by a gray colored donkey pelt, the odd touch came next with a spearing pain as a horny colt shoved his erect cock where his instincts suggested it belonged.
"Hey-a hee-haw," Jen brayed aloud as the slender colt cock slid inside her equine placed vulva.
The highly sensual insertion caused her vulva lips to begin winking in Jennet style, as part of her wanted the colt to breed her, and her real mindset knew she had had more than enough horny fun for that, or any day. Even as the mating began more of what was still in part human began changing more to look equine and donkey.
