Expectations are 90% of the delight, and after just once having felt the excitement of change, Dan had trouble sleeping. Sleep deprivation takes its toll by making a person irritable when awake, and Dan began then to be an irritation to his parents, as well a outright bastard when it came to being around his witch of a sister.
"Dan-Ass," is what Kat often referred to her brother when talking about him or even to his face. The more she said the nickname, the more Dan would give her a bray to thumb his nose at whatever she might want.
Many a night when sleep would not come to him, Dan laid on his bed feeling a gradual sense of arousal, he wishing his donkey self would come alive and let him run wild.
On dark rainy nights the aroused state made his maleness quite erect, and with him stroking it, the thing would grow, becoming equine in length and girth, but very bestial in its contour.
A lack of concern became the norm for Dan, his mother complaining openly to him about his bedsheets, and the sticky mess she had to deal with at least once each week.
Brash and bold, Dan would get up during some nights and stagger into the bedroom of his sister Kat. He would watch her as she slept, he still stroking his donkey sized cock, and when it spewed its load he would let a good bit of it dribble a puddle on the bedsheets, or on his sister's tummy.
Were-donkey like in so many ways, if Dan happened to go near some mares or jennet donkeys, and if any were having their times of estrus; he felt the arousal, a change, and became wholly donkified.
"Donkified," is a term used by Dan to his friends, he making fun of his curse, but to him it meant as a reminder when he had his Jackass stud fun with any a needy mare or jennet donkey.
One weekend Dan failed to return home, his parents became worried, calling around and asking of friends to Dan if they had seen him.
None luckily for Dan had not seen him, as while he was enjoying the length and girth of his donkey cock, the farmer came out, putting a halter on Dan and by such an item used commonly on such a beast, it maintained the curse, keeping Dan as a stud donkey. A Friday afternoon to late the next Monday, Dan found his donkified self as a thing of wonder, liking it so, he thought even of remaining in his halter and as a donkey.
Kat approached Dan, she inquired if while he was gone for near three days did he like it being a Ass?
Dan could think quickly and answered his spiteful sister with a sneering comment, one he had hope would stir her witch blood and have her make of him a donkey stud on a more permanent basis.
Nothing seemed to work and make Kat become irate enough to have her add to her spelled curse. It was Bobbie and Tom who met Kat at the market, they asking her if what Dan would become was catchy?
Kat was obviously surprised to learn that Dan had told his two friends of how he would change. As what they asked out of wonder and worry for their own safety, Kat thought it a worthwhile gesture, she changing her spell and giving Dan the ability to infect others by the semen he spread so well.
Dan noticed his testicles becoming much bigger when he would transform, whether when as part human and some like a donkey; or when aroused, he became a stud donkey and his balls were equal to those of a stallion Zebra. Huge big balls, his testicles brimming with infectious semen, easily able to impregnate a mare, jennet, or some human girlfriend. Dan learned to like his hefty load spewing ability, and when once he had to show the volume of a load to Tom, some of the semen landed on some bare skin, infecting Tom as if another were-donkey for their small town.
