Damon picks Buttercup. "So you want to be a Stallion huh? Looks like Lucky won't be the only stallion, in the stables, then."
The staghands then takes Lucky off stage. "Now Damon. Take off your clothes. You won't be needing them for your new life."
Damon takes his clothes off as he shows off his amazing body and cock. The audience were impressed. Even Madame Illusia was impressed.
"Alright Damon. You will mate with Buttercup. Just insert your cock into the beautiful mare."
Damon goes behind the mare. She didn't kick him. "Um how do I mount her?" Buttercup then shows off her mare vigina to Damon.
Damon goes up to her and inserts himself into her. He could feel his cock inside her. Buttercup felt warm inside.
"Well what are you waiting for Damon? First time with a mare? Don't worry. Buttercup will go easy on you. It should be like having sex with a women."
The audience laugh. Damon then begins to hump Buttercup. He was having sex, with a horse, and it felt good.
He could feel his cock go in, and out, as his changes start as the audience watch. Seeing a grown man have sex with a horse.
