The manufacturers of the Chronivac have always had customer experience foremost in their designs, which explained the degree of detail that users can program into the parameters for changes and transformations.
Matt chose the extreme settings, which is what he would have done had this been one of his favorite video games. For the Chronivac's programming, though, that meant he wanted his restoration set as an almost impossible tasks. In theory, what could have been easier? A quick and dirty ejaculation, and he was back on two legs and get back to his new boyfriend.
Matt had also allowed the device to cheat, more or less, by using mild reality alterations to affect Matt's attempts at restoration.
So, when Matt discovered a receptive jenny in the field with him, he had managed to overcome his squeamishness and get up on the other dirty donkey, but the moment the mounting took place, the Chronivac implemented a powerful suggestion to a farmhand in the nearby barn. The young man noticed the jack going at it with the jenny and, although he would not have been able to explain the motivation for his actions, he took a high-pressure water hose and blasted the horny jackass and its paramour du jour.
"What the..." Matt spluttered, ending what had been a precarious mount on the difficult jenny. His cock slipped back out of the jenny only moments after he had managed awkwardly to get it in.
Except all he produced were brutish brays that still managed to get his anger and frustration across.
The man just laughed at the braying jackass and let him have another blast of water directly in the face. Water got into Matt's oversized nostrils and in his ridiculously large ears.
Needless to say, two blasts of cold water had a debilitating affect on even his energetic erection. His cock soon shrunk and returned to its sheath as the jenny, never all that enthusiastic in the first place, wandered off and refused to return despite Matt's insistent braying.
Matt, cursing the interference from the farmhand, didn't believe he had too much cause for concern. His restoration had just been delayed, not thwarted. He would try again once the man's attention was elsewhere.
He would have counted down the minutes, but his donkey body wanted food. The compulsion to graze struck almost without warning. Matt's thoughts on ejaculation got submerged beneath the animal's need to constantly forage to fuel its large body. He lowered his head and opened the jaws with those ugly, blocky teeth and sheared off some plant matter, chewing slowly and methodically.
