Ty snorts with a chuckle at the farmer wife's begging, stroking his throbbing horse shaft while slowly pointing it to the boy. "You're a horny young stud, aren't you? Well you get my gift now, little boy.." Ty shoots a few ropes of cum onto the boy's face, making him wince and squirm as the warm, horse goo splatters against his cheeks and lips. In a matter of seconds the boy was wiping the jizz off his face and licking it from his hands, softly moaning the whole time.
"M-mommy the horse's cum taste so good.." The boy sighs out with pleasure, then starts voilently convulsing as his body vibrates on the couch. "Wha-WHAT IS HAPPENING TO MEEE!?!" He moans out in confusion and ecstasy as his body starts transforming, his muscles gaining a bit of mass while his height grows just by a few feet. "A-AAHH MOMMY IT FEELS SO GOOD!" The boy's tiny cock grew to at least a foot in a half, the skin molting into a darker color as the member itself becomes more horse like.
"You looking so fucking hot right now, my baby boy! Embrace your new change!" The mother encourages her transforming child, shoving three fingers into her pussy to finger herself at a very fast pace. Ty stood there and strokes his cock with both hands, getting off on the sight of the farmer's boy turning into a raging, horny stud. The boy's feet turn into hooves, and finally his head shifts and extends, weakly crying out before the change was finally complete.
"NEEEIIGGHHH!! THIS IS SO WONDERFUL!" He jeers out, standing up to admire his new body. Now being the same height as his mother, the new stallion's nose caught a whiff of her heat, and immediately turns around to insert the tip inside her wet pussy. Once the head felt her warm juices, the stallion starts to thrust hard and fast without even thinking about being gentle to his mother. "I LOVE YOU SO MUCH MOTHER!! I WANT YOU TO CARRY MY CHILDREN!"
"YES BABY YESSYESSYEEEESSS!! BREED YOUR MOMMY!! O-OOHH THIS IS THE HAPPIEST DAY OF MY LIFE!!" She screams out and orgasms, her inner walls tightening around her son's thick horse-cock.
"A-AAHHH IM GONNA CUMM!!! NNEEEIIIGGGGHHH!" The young stallion thrust one last time and explodes his seed inside his mother, cum gushing out from her pussy to flood it's way around from his shaft.
"A-AAAAHHH YYeEEEEEeeeEEeessssss" She moans and curls her toes, feeling the intense afterglow taking over them. Ty grunts and neighs as well, Cumming as he shoots a few splashes of cum on the boy stallion's back. The young stallion pulls out of his mother and softly neighs with delight, giggling as the cum hits his backside.
"Great job, boy..but now it's my turn.." Ty smirks and takes a few steps closer..
