Roger stood thinking, he vividly recalled what Mable whispered in his ear her greatest worry, of if it happened, that she having drunk some of the blue powder in a drink left in the fridge, that she too changed, asked of her husband that he not let either of the boys have her for a mate, she begged. With that remembered thought Roger stepped away from his dear wife as she began to grow donkey fur sprouting on her forehead, ears, and gaining lips of a donkey muzzle. He beckoning, led Marge along the main isle to where son and donkey Jackass Brian stood all horny there inside his stall.
Roger asked of "Brian about his mother if she drank some of the blue mixture, maybe a cup full, was that enough for her to change too? His still human thinking son in donkified jackass self then looked at his parents, and presented Mom with his true Donkey style grin and with a right hoof tapped just once to the stall floor as signifying in the affirmative, as she too would begin feeling the pangs of a beastly existence. She tried to speak with Roger only issued forth a gravelly sounding bray. She clamped her then furry hands over the fast expanding lips and gave a really scared look to her Husband. Reaching to give Roger a hug he pushed her away. Then with her braying voice she burst into tears, emotions ran deep in that moment. Marge changing, as her desire to remain a person and the wife to Roger did little to have him want her. His very defiant manners showed his feeling repulsed by what she was becoming, made the changes rush to envelope her all the more.
Roger stood watching as she his wife her body expanded tearing her clothes, while the woman became a Donkey. Mable cried as bit by part of her body changed. It was then her growing of the tailbone began that she fainted there on the barn floor. Minutes felt like hours and became then two hours as Mable became a large and mature Jenny. A nervous swinging tail and her soft snorting had both Brian and Elroy standing each with a enraged erection. Elroy pawed at the floor and screamed his male bray wish to get at as capture Mable in a real foreleg hug.
Roger remembered how he stood silent as watched the fear well up in his changed Wife. When he offered her a friendly patting to her strong and hairy neck, she recoiled with a snapping bite of her large teeth. Although he offered her his apology as said "Sorry Dear, I was only trying to offer you some comfort in this time!"
He rubbed a hand over the injured side of his thigh. Turning he looked about and with a quick move grabbed from a hook one horse halter. Quick and nimble he pulled it over the jennet donkey head, clipping it tight and fast before she could try and bite again. His blatant action caused Marge some disgust with him for treating her like some vicious beast. He then rein-clipped to her halter as led her to a stall of her own. She, he told her to stay there and be good, while he left the barn to check, seeing what he could arranged.
Roger ventured back into the main house and after cleaning up the dishes in the sink, he went about preparing his evening dinner. Unbeknown then as note later, Roger learned from his hire helpers about two virile male donkeys, his changed sons Brian and Elroy stuck in their stalls had nostrils pointed high up in the air, each had a flehmen reaction happening, gathering the heady scent of a female Donkey. Prancing about inside their stalls, both Donkeys sported big erections, each had a cock swaying and swinging, they filled with lust.
Mable was not dumb to all this noise and from her new body came similar urges. Urges to let the boys have their way with her, and together in fun settle the wild desires she felt as her Donkey Jenny form. It was near midnight when Elroy being older than Brian and thus a larger and more mature Donkey, he finally jumped the side rail of his stall. He brayed as his cock flared and looking at she his conquest with wild eyes moved closer and closer to be with Marge. Mable too was seen having her reactions of whites of her large eyes showing fear of what was to come. Stuck with her large round butt facing the aisle, she stood reined to where she could not move more and a foot either way.
Elroy reached his head out and sniffing Marge about her furry rear, I heard him bray with delight.
Marge stood there stiffly scared to death, she a farmer's wife knew, had seen what was to happen, as I expect she had deep instinctive desires what drove her to want his male attentions. The more she tried to swing her rear away from Elroy and his advances, the more the virile male Donkey went wild. Roger heard the commotion, his first thought was to check on Marge, as see if some stray dog had gone into the barn. Quickly he ran to the barn and switched on the large ceiling light. There he stood, his mouth open and eyes wide as Marge stood in the barn aisle with her donkified son Elroy standing mounted, his cock buried deep, was humping Marge.
Marge seeing then her husband looked to him to stop his stud donkey son from defaming his wife. She brayed softly as if her mind was being taunted by the raw animal sex buried in her black vagina. Roger looked at Elroy, seeing there Brian standing not far away, he as well sporting a virile male erection. Brian stepped back inside his stall, letting his brother Elroy to hump and pump for yet another loving round. With the second rutting romp, Marge began to push back making Elroy's cock go so deep his sheath parted the lips of that black skinned vagina. His grunting delights mixed with those from Marge, her moans of female enjoyment.
I knew as did Roger remembered of his wife doing much the same when they made love often in the barn, in a stall, I expect he felt betrayed. Roger acted with dismay of his lost love life, he hearing Marge bray for him to come to her defense, as he called back to her, said, "Enjoy it dear you've crossed the line, be a Donkey!"
Roger knew that I knew, we having seen Marge mating several times with Elroy, both then being donkey animals, as incest laws bind humans not animals to living within a moral existence.
