Well, no doubt about it, stallions have it made. Damon was sky high putting his new dick to use inside an actual mare. He orgasmed way faster than he had with any woman. He felt his long tail twitching while the semen gushed down his two foot horse dick into his forbidden lover. He hunched over her and got a few more pumps in there before it was time to dismount. His horse dick flopped down out of her rear end. The bell shaped head dribbled a few sticky gobs onto floor of the stall. Damon was glad he wished for this.
Damon felt a breeze through his hair and realize that he had a lot more of it now. Reaching down his neck and upper back, he felt a long line of silky long hair like the kind on his tail. It made him a little bit nervous to realize that he was now a little more like a horse. He knew he hadn't thought about how much he might change the second time, and he was just lucky that it was mane instead of hooves or a long snout that he couldn't hide from his family. For all he knew, he could have turned all the way into a horse just by having sex with one. He hadn't cared because he had given himself in totally to being a stud. Now he has a mane and a tail. More sex could mean more changes and he'd better undo this wish when he gets back.
"It's okay, I can control myself," he lied. "I just have to get through the rest of this visit, stop being so horny, and let the genie change me back later. It's fine."
He walked back deeply embarrassed even though no one had seen him, just knowing what he had done. His aunt and uncle would eventually discover their mare is pregnant, and only Damon would know why. There was going to be a new foal on this farm because of him. He didn't really know what to think of that and tried to put this little escapade out of his mind. It was hard to do that with the breeze blowing through his mane.
Damon was scared, happy, and confused. When he made the wish, it was just to make himself feel better after his girlfriend broke up with him. He still wanted to think that's what it was, but he knew he was now in it for the pure animalistic lust. If he kept sampling the pleasures of stallionhood, he was soon going to end up with the whole package.
