The old woman's eyes widen and a smile of a friendly sort comes over her face. "I see then you are willing only to remain a male even if it cost you those nuts. You have backbone and a sense of personal honor, this is unexpected and in my opinion very good for you! I will change my mind and offer you one of two deals both of which will finish in your return to humanity, interested?" she asks.
Donkey or man I'd have to be crazy not to listen, so I gave the knod of a donkey's head.
"First, you can remain here on the farm as a full working stud sire to breed the jenny's as needed. Then in five years returning to your youthful human male form if you desire to of course?"
"Second, you must accept the form of a Highland medium draft horse. A stallion pure and true as you stand 14 hands high and massive of sexual ability. I need you of dun colour and black mane and tail. A stud you will remain for not less than ten years. A daily breeding of one mare or more as long as your stamina holds. The best of stabled conditions, heated, air conditioned, insect controls, you will be treated as the king of a herd. Then as the ability leaves you less effective I will return you to your youthful age and allow you to be human. The memories of either lifestyle will be yours for life, now which would you choose?" asked the old woman as the stablehand glared in surprise.
