Early in the morning, Dean woke up and started typing in the Chronivac. He setted his tranfomation into a Thoroughbred stallion, 4 years old, and for three hours. He also setted it so everyone-exept for him and Jeff-would think that he's Thunder, the massive black stallion that came second in the race.
Like Jeff's transformation, the first thing that changed were his ears. He felt them twitching and lenghening, and touched the fur-covered flesh in enjoyment. He is becoming a horse!
His legs were next, changing into big black hooves. He raised one hoof, struggling to keep his balance, and knocked on it. He haven't felt a thing. 'Wow, horses really can't feel their hooves!'
Next, his new tail bursted out. He noticed it was much shorter than Jeff's, but he didn't care. It was so cool to have a tail.
His arms followed, transformung into horse's front legs. His hands mashed together, becoming another set of hooves. His new legs shifted their position, aqquiring a much more equine-like position.
His back was next. He fell down onto all fours, and couldn't make himself raise up. "Guess I'm walking on all fours now," He told to himself. His back and belly changed aswell, making him more horse than human already.
He felt his privates burning, but unlike Jeff, he could felt his dick changing, becoming a stallion's sheath, and growing along with his balls.
And lastly, came the head change. His face pushed itself unward, forming a snout.
Now completely a horse, stallion Dean neighed in excitment, and started walking slowly towards the stables, trying to adjust to his new walking style.
He entered the stable, and walked into Jeff's-Sahara's-stall, waking him up. Jeff neighed, and suprisingly, Dean understanded him as thou as he was talking in english. "Dean, is that you?"
"Yep, it's me. Like what you see?" He teased, catching the mare's intoxicating scent.
"Oh! I can understand you!" said Jeff happily. "And-oh, what is that scent?" He asked, sniffing Dean's body. "You smell so... manly," He whinneyd in embaressment. Dean neighed in laughter, turning his body and exposing his new stallion dick, who started pulling out of his sheath.
"Oh..." whinnyed Jeff, "So you were serious about... mounting with me."
"I sure was," Said Dean, approaching the mare slowly. Out of pure instinct, Jeff turned around and lifted his tail, exposing his wet vaulva. Dean sniffed, and got into action. He started licking Jeff's backside, and Jeff shivered in pleasure. "Oh, come on, you beatiful stallion, take me already!"
Dean continued his licking, teasing him. "You sure you want me inside you? You sure you want to be my mare?"
"Yes! Yes I do! Please, just... Just fuck me already," moaned the Jeff, the stallion's scent driving her crazy. "Take meeeighe!"
"Well, you asked for it, girl," Sid Dean, his cock hard and throbbing. He got even closer, and mounted his best friend, Sahara the mare. The mare and the stallion whinnyed together in lust and pleasure, as the stallion thrusted again and again.
The mating lasted for only a few minutes, and after Dean dismounted Jeff, they both fell down, exhausted.
"What have we just done?" Asked Jeff in panic that turned fast into anger. "You made me fuck with an animal!"
"Don't try to blame me. You wanted that, don't be a liar. You've enjoyed it. And I changed it so we'll both change back right now, so you should be happy."
The mare neighed in annoyence. "But why? Why, Dean? Why couldn't you just change me back?"
"You know that I've always had a crush on you, right, Jeff?"
"Yes, I know, but... as an animal?"
"At the beginning, it was just a joke. Turning you to a mare, and not a stallion. But as the weeks progressed... I fell in love with you, as a female horse. And I just had to try it, just once."
Jeff have'nt responded. He stomped the ground several times, and asked: "We will never be the same, will we?"
"No. Our friendship has just changed, but I still love you-just now not only as a friend, but also as a mate."
The nare nickered. "You know... being a mare really was interesting. And mating with you was pleasurable beyond anything I've expected. But you gotta promise me, if you want to to ever do something like that again, that next time, you'll tell me EVERYTHING, you got it? Everything, or else we're done for."
Dean snorted. "Sure thing, dude. We have a deal. And, speaking of the devil... I have another interesting idea for us, but you'll have to wait until we're changed back. You're gonna love it, I'm sure."
"Right. We'll see about that. And... Hey, Dean, you're changing!"
"You too, Sahara... Jeff. As i said, we're turning back right now."
Both the stallion and the mare's boddy got thinner and thinner, their arms and legs reverting to being human, and their tails dissapearing. Their heads returned to normal, and they stood on two legs again. Then their ears changed... and their genitalias, becoming human dicks, for Jeff's relief-and Dean's dissapointment. The boys looked at each other, and hugged. Jeff blushed. "Dude... let's find purselves some clothes first."
Jeff and Dean exited the stall, and wore their clothes. "So, what have you started to say about an idea you got?" Asked Jeff, curious. Dean laughed. "Wow, you really liked that, didn't you?"
Jeff blushed again, and kept his silence. Dean laughed. "I'm just messing with you, dude. Now, here's my idea..."
