The sun was shining brightly that day as the cool air began to move slowly across the land. The trees were already changing with the weather, while the wind was sending a beautiful cascade of different colored leaves flying through the air before finding a resting place on the ground below.

Twilight, Rarity and Applejack had gotten together at the farm for a small bonfire outside to cook some smores and have a pleasant conversation about the summer past. Midnight had arrived from his small trip into town to gather a the few items needed to make the smores. He took a seat across from the three mares as he listened to them chat away.

"I'm telling you Twilight, darling, this past summer was the absolute worst heat that I have ever experienced. Ask Midnight. It took everything I had not to just hold him down and have my way with him." Rarity giggled as she looked to the Alicorn, biting her lip seductively as he gazed into the fire, not paying much attention to the girls.

"My heat was no different than before. But knowing I had a coltfriend made it all that much worse. I had to cast a cooling spell on myself several times a day. Twice more when I saw Midnight. After the first couple of days I had to run him off before I did anything drastic to him." Twilight grinned sheepishly.

"Mah heat wasn't to bad this time'round. Ah'm always used to having a stallion'round the farm cause'o Big Macintosh. It's a mite rough time though knowin ya got a stallion out there willing and ready for ya though. The thought'lone got me all worked up on many'occasion." AJ chuckled looking over to Midnight.

"Come on girls, it couldn't be as bad as your playing it out to be." Midnight laughed as he spoke from across the small fire.

"Midnight darling, you have absolutely no clue how hard it is to be a mare in season. Imagine yourself as a mare and multiplying your thirst to rut by a thousand. That is what it is like to be in season." Rarity sighed.

"There is no way that being in heat is that bad." He groaned in annoyance not believing them for a second.

Twilight placed a hoof onto her chin in thought, catching the other two mares attention.

"Hu oh! Ah see that lil twinkle in yer eye Twi. What'cha cooking up over there." AJ snickered causing everypony to look at her.

"I was just thinking about showing Night how it feels to be in heat, and possibly make a little wager if you girls are up to it." She giggled staring down Midnight from across the fire pit.

"Oh boy, another bet I can win." Midnight chuckled but it slowed to a stop seeing Twilight's smile turn a little more sinister.

"Oh I think we could win this bet all to easy." Twilight chuckled causing him to cock a brow at her.

"What's the prize?" Midnight grinned.

Twilight stopped for a moment as she nodded to the other two mares as her horn lit up placing a sound proof globe around them. They talked for a minute before staring at Midnight with an evil grin each, this only causing him to grin back because out of all of his prior bets with the girls, he had always come out on top. He felt that this time would be no different.

The shield around the girls disappeared as they moved back to their spots with a smug grin spread across their faces.

"Come to a decision on the prize girls?" He chuckled.

"Eeyup, the prize'll be anything you want. That includes having us all three at once if you want." AJ grinned giving him a wink.

Now I'm sure you have heard about how Midnight, when surprised by something he desires, will have his mane and tail erupt into an inferno. This time was no different to tell you the truth. The only difference this time though was the relative size of the inferno which made a forest fire look like a ten dollar grill that was about to putter out in a plume of smoke.

"I'm in!" He spoke as a grin spread across his face.

"But you don't even know what the bet is about." Twilight piped up.

"Don't care, as long as it has nothing to do with spiders, I'll do it." He grinned widely.

Twilight smirked looking back to the others who only smiled back.

"Are you fucking serious?!" Midnight yelled in disbelief.

"Totally." The three mares laughed.

"And in such a case as I give in and rut with a pony I won't get pregnant?" He groaned in annoyance.

"That's right." Rarity giggled.

"UGH! Fine, if it's only for a week then I'm sure I won't loose." He sighed.

Over the last few minutes the girls had discussed with Midnight about the contest of sorts. He would agree to be turned into a mare for exactly one week. He would keep his normal coat color but it would change to a bright white should he loose and give in by rutting with any other pony, including one made by magic. He could clop all he wants but the girls knew that would only make the heat far worse. He would also have a spell cast on himself so that the heat would be magic based and he would not get pregnant in his mare form. Upon agreeing that the girls prizes would be anything they would want as well, Midnight had been turned into a mare by Twilight.

"This feels really weird being a mare." He spoke as he trotted around.

"And why does it feel weird?" Twilight asked giving a cocked brow.

"Because I don't have my balls smacking against the inside of my legs, not to mention my...."

"OK! I think we get the picture." Twilight spoke up as all three of them blushed furiously.

"So is this it? I don't feel the urge to suddenly rut anypony in sight." Midnight chuckled looking around, mainly at the girls.

"Hang on a sec." AJ grinned as she stepped inside the farmhouse for a minute.

"I still have yet to cast the heat spell on you Night." Twilight smirked.

"That's another thing, I think the town will get a funny vibe when they see me like this. Maybe I should change things up a bit." He spoke up catching Twilight and Rarity's attentions.

The two ponies watched as Midnight began to use his magic to turn his horn invisible, and his mane and tail into a tangible hair. After a few more seconds the color of them change to that of a bright silver. His eyes turning into a sky blue as well.

"Hows this? Think I could pass myself off as another pony?" He smirked seeing the two mares gawking at him blushing.

"That's fine, now for the heat spell." Twilight said as she shook herself back from her stupor, her horn lighting up as a beam shot out, connecting with Midnight.

(At this point in time we shall now call Midnight a she since he has turned into the opposite sex)

Midnight staggered for a moment before coming back to reality. "This isn't so bad. Its a little uncomfortable but other than that I don't feel the urge to go rutting with everypony I see." she chuckled. "I should also change my name as well." She thought for a moment before smiling. "Call me Night Wind."

"Ahem, Night Wind, ah gots a surprise for ya." AJ called out as she walked up behind the stallion turned mare.

"Really now, what's the......sur....pri-hi-hi-hise." She trailed of giving a dreamy look as her vision fell upon Big Macintosh.

"Eeyup, ya'll er gonna win this bet." Big Macintosh chuckled as Night began to drool slightly before shaking herself back to reality.

"What the hell?!" She shouted. "You seriously have to put up with these feelings while in heat?!" HOLY CRAP!" She shouted as the fear of loosing this bet was beginning to become all to clear to her now.

"Ya can still call the bet off sugarcube." AJ chuckled. "But not without some con-see-quences."

"No way, I am going to get through this bet and win!" He smirked giving a determined stance.

"Ya sure about that?" Big Macintosh chuckled before blowing into her ear seductively causing her to bolt to the side blushing furiously.

"THAT'S NOT FAIR!" She choked out shakily, the blush showing through her dark coat.

"Ah ah aaahhhhh. We never set any ground rules on how to play other than the few rules we set for you." Twilight giggled watching the expression of horror rip across Night Winds face.

"Oh my God, what have I done?!" Night Wind choked out as her flank hit the ground in shock.
