As the barn door opened Max's human mother walked in. Judy was 35 years old. She had blonde hair like her son and was quite
attractive. She had followed her son to the barn and watched through the window as her ten year old boy removed his clothes, put his
horse penis into the mare, started to have sex with the horse, and then turn into a fully grown stallion right before her eyes. She walked
nervously towards her former son trying to understand what had happened to him. Max however had other plans. He no longer recognized
her as his mother, but as a possible mate. He moved towards her and nuzzled a her shirt causing it to unbutton revealing her d cup breast
under her bra. This caused Judy to fall over, she tried to crawl away in fear realizing that her son didn't seem to recognize her. Max
grabbed her pants with his teeth and ripped them off along with her under where, revealing her purfect heart shaped ass. His cock was
bigger than ever now as Judy got up on all fours to try to stand up, Max jumped on top of her, his front legs settling around her waste. His
weight was startling and Judy didn't know how she could hold him up. Once Max's cock pressed up against her now exposed pussylips,
his dark cock carefully slipped inside her small vagina. Judy moaned as the gigantic horse cock entered her, he started pumping inside of
his former mother as she began to change. The silver necklace around her neck started to tighten before snapping off her neck and
landing in the straw on the barn floor. " no...Max.. Please...stop" Judy cried as her son pumped his massive cock into her. The muscles in
her body tensed as her jeans stretched along her backside. As it started to rip at he seams, she could feel her legs growing visibly more
powerful. Judy moaned as her hands and feet Los there human shape, and turned into hooved legs. As Judy transformed she was able to
grow the muscles to withstand her sons weight. Then she heard her sons voice in her head. "Mom jus let this happen, don't resist, your
getting bigger and I know you will be a beautiful horse and I already know that you will be a wonderful mother". Judy smiled as her son
continued to pump his cock insider her, she stopped resisting and shut her eyes as she felt her mind begin to change, as she fled her
body turn into a horse. Her pussy made a cute sopping sounds from her changing inner canals and the huge cock that intruded her. She
gained more desires to bear her new lovers child, longing for his seed. The feeling inside he pussy got more intense as her inner vagina
grew bigger, adjusting itself to the size of a horse. Her change still progressing, her hair grew into a majestic looking mane while her
human teeth fell out of her gums and got replaced by bulky horse ones. Her intestines and womb changed, growing to fit her big frame,
and her eggs lost their human DNA and instead grew sensitive to equine seed. Her neck stretched out and her chest barreled outward as
her breast moved down to form her udder, her nipples blackend and elongated. Her shirt ripped down her back, showing her new muscled
physique. She grew dense white over her body while Judy whinnied softly with her changing from he feeling of her lovers cock pumping
away inside her. Judy's now big eyes moved to he sides of her head, her face stretched out to form her horse muzzle and her now pointy
ears moved toward the top of her head. Her changes nearing the end, Judy suddenly felt the feeling she was longing for. Max pumped
inside of her one last time, his huge dark balls tensing as his seed flows into her willing womb. Both lovers whinnied proudly while Judy's
fate as a horse was sealed. Together the two horses now stood proudly in the barn as a family.
