Applejack shook her head as she got dressed in the locker room, attaching some elbow pads, knee pads and a helmet to her toned anthro body. She wore pretty much nothing else but a smile on her face. Her breasts weren't too big thanks to the hard work she did at the farm keeping her trim and strong, and her sheath hid a surprise that could rival Big Mac's. “Ah don't know who done challenged me ta' a match in a sport I dominate in,” she chuckled to herself, “Or if'n they know what happens ta' the losers, but I don't rightly care! I'm undefeated in all mah matches.”

Before she could dwell any longer on her thoughts about who could have challenged her, a fully clothed unicorn stallion entered the room. He was the owner of the sports arena that held the matches every month. “AJ!” he exclaimed, a mix of excitement and happiness in his voice. “It's almost time for the run to start, are ya' ready?”

“I sure as shoot, am, Mister Derby, but I have ta' ask... Who's th' pony that done challenged me?” She glanced at a poster of the match on the wall, which of course was less helpful than ever. It had a picture of her bust and under that, her name, but the opponent's slot was a big question mark. Underneath the question mark it just had, 'Super Special Secret Opponent!'

“Now AJ, I've told you a million times since this match was set up. I can't tell you that! This surprise match between you and your opponent is raking in the bits!”

AJ rolled her eyes. She wasn't surprised the owner of a sports arena would be more concerned with profit than her own curiosity. She held up a finger and opened her mouth, about to speak, when Derby cut her off. “No more questions, it's time for the match. Let's go! Hustle hustle, we can't keep your fans waiting, now, can we?”

She sighed and shook her head some. “No... I suppose not. 'Sides,” Applejack replied, getting a small smile on her face. “I'm gonna find out who it is when we're introduced into the arena.” She felt a push to her shoulders and back, getting rushed out the locker room. Once in the hall, she could hear the roar of the crowd, and the announcer for the match already doing her intro. She hopped a couple of times, careful to not trip on the skates she was wearing. “Ok AJ, you can do this...” she muttered to herself. “No matter who th' opponent is... you're number one. You've never lost a match...”

The crowd was going wild, the noise almost deafening. AJ waved to the crowd as she stepped out and made her way to the track. Each step caused her breasts to bounce and her balls to swing back and forth. She didn't even pay attention to her intro, having heard the laud and praise so many times before. How she was undefeated, one of the fiercest competitors... it's not like she didn't already KNOW that... Instead, she kept her eyes trained on the large jumbotron, waiting to find out her opponent. Suddenly, the crowd was hushed. It was time.

“AND NOW! Introducing her opponent! ALSO hailing from Sweet Apple Acres, a relatively new and upcoming roller. Undefeated in all his own matches...”

It was at that point that Applejack stopped listening, her face blanching. She turned to look at the owner standing next to her, an angry expression on her face. She opened her mouth to speak, but Mister Derby was already speaking. “Brother vs Sister! Both undefeated!” he said quickly and happily. “How could this event NOT make headlines and bits.”

AJ ground her teeth together in anger. “Yeah, and? Ya' DO know what happens to th' loser, right? Sweet Apple Acres can't go without either o' us!” She was about to continue complaining when a large stack of papers is shoved in her face.

“You're contracted to do these matches, so stop complaining and go out there and make me money!”

Applejack was crestfallen. He was right, and she was stuck doing the match. Big Mac, on the other hand, had known about the match ever since it was set up. He knew that he should have been more upset about the match up, but as an up and coming star that rivaled Applejack's fame, he knew this outcome was inevitable.

Slowly Applejack walked onto the track, rubbing idly on her sheath and teasing at her balls. Her cock slowly unsheathed as she walked up to Big Macintosh. “Howdy, bro...” She looked over him, his own sheath plumped out, cock throbbing a little. “So, ya' knew about the match and didn't tell me?”

“Eeyup.”

“Ya know I'm not gonna go easy on ya just cause yer my brother, right?”

“Eeyup.”

“And I'm guessin' you won't go easy on me, neither?”

“Eenope.”

The pair walked onto the track and got ready at the starting line. They both looked up at the jumbotron, listening to the rules. They had heard them time and time again, but it was always good to get a refresher.

“The rules of Roller Derby Sexcapade are quite simple. Win at any cost! Nothing is off limits, nothing is illegal after the first two laps! The match only ends when somepony has a full, squirming ball sack!”

Applejack and Big Mac glanced at one another, staring each other down. Quickly their attention returned to the track, getting into starting position. The seconds ticked by, anticipation showing on both their faces. A quick glance to the side by Applejack, she gulped. She was caught between a cock and a hard place but she knew... she HAD to win. Her body flexed; so did Big Mac's. Soon, the sound of the crowd and the world around the pair faded as the start gun fired.

The crowds, their noise, all of it wasn't important to the pair of ponies as they started the first two laps. Big Macintosh took the lead, a strategy that Applejack tended to use. She would always hang back and let her opponent take the lead. The first two laps were really only important for a couple of things: getting the opponents sweaty enough to make slipping in easier, and tiring out the athletes.

The first two laps went by without any fouls or errors, Big Macintosh covered in sweat by now. Despite how in shape he was, he had pushed himself a bit too much, breathing hard. Applejack, on the other hand, had taken the first two laps rather easily. She was covered in sweat as well, but wasn't breathing as hard. As soon as she had crossed the line, a loud siren sounded and the crowd roared louder. Now the match was really beginning.

Big Macintosh was having a bit of trouble keeping up his speed, or more, perhaps he was slowing down enough to engage with Applejack. The two ended up skating next to each other, the pair covered in sweat. Big Macintosh made the first move, creeping close to Applejack. He reached out and groped at her chest, trying to get her off balance. Applejack was already expecting a move like that, most up and comers would use that tactic and, had she been any other mare, it might have worked. Instead, she grabbed Big Mac's arms and gave a tug, pulling him closer.

“Nothin' against ya', bro, but ya' bucked up.”

Another tug closer, yet neither fell over. Applejack shifted her weight a little, pulled a bit harder, and shoved her brother's hands into the tip of her cock. With how sweaty he was, his hands and arms slipped in quite easily. Big Macintosh found himself pulled closer to the herm, face pressed to her belly. “No sense fightin now, ya' lost!”

Despite his fighting, Big Macintosh found himself getting pulled further in. Quickly he found his head pressed to the tip, the slit stretching around his snout. His nostrils flared as he breathed in the apple scent from inside. In any other situation, he might savor the smell, but he was being pulled in even faster. Soon his vision became dark, his whole head in the cock. A bulge formed from the part that was inside the tight constricting tube though, as more of his body slipped in he began to squirm.

Applejack was soon at a point where she could no longer skate, so she slowly stopped and sat down. A hand reached down to stroke at the squirming bulge as her brother slipped further and further in. Soon the only parts of Big Mac left outside the cock was his tail, which was slurped up unceremoniously with a lewd 'schlurp' sound. Applejack dropped her other hand to massage at the bulge, squirming a little from her own touches and her brother's squirms. Those squirms made it difficult for her to not cum then and there, but she bit her lip. She forced that bulge down rather quickly, one of her balls starting to expand to accept her opponent.

A few more minutes and the bulge in her cock that was her brother disappeared, her sack stretched tight. She rubbed her hands over the stretched, filled sack a few times, panting and groaning loudly.

“WINNER! APPLEJACK!” came the announcer's voice.

Applejack waved to the crowd as she stood up and stretched. She did love showing off her squirming, bulging sack after her win. Slowly she dropped both her hands to her cock and started to pump. The cameras got a close up of her stroking, though it was more focused on the frantically squirming bulge.
