Sometimes you really don't know what you get yourself into. That’s what Shining Armor was thinking after his sister Twilight Sparkle had invited him to an event that was suppose to be a picnic in woods for the old times sake. However, such occasion was actually an excuse for a sex party: he and some other stallion, Big Macintosh, were actually supposed to have sex with each others sisters, pretending they were de facto doing it with their own little sisters!

Not that he was complaining, though. As he was a little reluctant at first, he finally gave in, and all his troubles melted away, quite literally, when he ejaculated gallons of his virile semen after a long oral session with Big Macintosh’s sister Applejack.

And before he knew it, Applejack had aimed his erupting member towards Twilight’s face, making him involuntarily commit incest! But for some reason he didn’t care. He knew he had some explaining to do for his loving wife, Princess Cadence, but luckily their marriage was pretty open: instead of being concerned of Shining cheating on her, she would get upset for not being invited to watch!

"Who's ready for round two?" Applejack said to her partners after their session was done.

"Seconds?" Shining asked Applejack as he was gasping for air, "Sheesh, gimme a second, would you?"

Applejack smirked at his messy face that had gotten sticky by her juices, having just rubbed her pussy against his snout.

"Come on Big Mac," Applejack said, turning her attention to her brother, "you ready for some more action?"

"Eeyup!" he said. He nodded yes but it seemed that ole' Little Mac was still taking a break. It had been only a couple of minutes since he had shot his load into Twilight’s mouth after one of the best blowjobs he had ever received!

"Well let's see, if we can't get you going again," she said, looking at the mess Shining was wearing behind her. She had so many ideas inside her head, waiting to be come out.

But whatever it was, she had to put them aside for a moment, as Shining rose up from his spot and started trotting towards the nearby tree.

”Oh, where are you going, Shining?” Twilight asked curiously, worried if Shining had gotten enough of their picnic.

”Gotta spring a leak, Twily!” Shining replied, ”Be right back!”

”Mmm, okay… Wait, W-WHAT?!! Twilight noticed Shining was straightening himself by a tree only a couple of feet away from them, where they could clearly see him, ”Y-you’re going to do it next to us?!!”

”Oh, ya gonna show off your sausage again?” Applejack smirked and took a better position, ”This ah gotta see!”

”Hey, you both have already seen my cock," Shining replied calmly, ”I have nothing to hide anymore!”

”Y-yes, I suppose…” Twilight looked down as she blushed, ”But it’s just… It’s not normal!”

”Twilight, we already sucked their cocks while they watched!” Applejack rolled her eyes, ”Ya think that’s kinda normal?”

”Oh, right!” Twilight grinned nervously, ”I guess we have already broken some rules here…”

”Just sit back and enjoy, Twi!” Applejack reassured, ”You ain’t gonna see something like this very often!”

Big Mac turned his head away at the same time as Shining let his horsecock drop out of his sheath. Even in its flaccid state it was quite a marvel: it was as thick as Twilight’s hoof and its throbbing shaft was bulging with veins, big enough for somepony to land a helicopter on it!

Shining was leaning against the tree with his other hoof while he started aiming himself with the other one, and soon let out a stream of clear liquid that arced down on the base of the tree.

”Aawright, work on it, sugarcube!” Applejack said in excitement and leaned closer to the action. Twilight on the other hoof tried to look away as she blushed profusely, she felt uncomfortable watching her brother doing something so disgusting in front of her. She wringed her nose as she smelled it.

Not that she had ever seen Shining doing that, though. Ever so often she had entered the bathroom carelessly, accidentally walking in on him while he stood to urinate into the toilet, something which she wasn’t so proud of. She was very aware of the pony biology, having been read about it many times, but she didn’t care to see something like it with her eyes.

It wasn’t that she didn’t enjoy seeing her brother’s penis on some occasions, as she had fantasized about it many time while masturbating, it just wasn’t the context she wasn’t keen of - she associated urinating with dirtiness like many other unicorns did.

Shining groaned loudly as he kept going, the amount of his piss growing in volume, his meatspear twiching in his grasp. He had created a small waterfall cascading down the tree and it was starting to form a puddle dangerously close his hooves. He started waving his dick from side to side as if he was marking the tree as his own.

”Damn, boy! That’s a lot of pee!” Applejack saw getting wet as kept staring. Her fleshy pearl of clitoris was poking out of her folds as her lips swelled, getting ready for some action. ”Ya could start a fire department and put out forest fires with that!”

”Well, I do have a hose for that!” Shining winked back at her, while Twilight squirmed in embarrasment. How could his brother be so casual about any of this?

”H-how can you enjoy this, Applejack?” she asked in confusion, ”Peeing is so gross!”

”Hey, when ya live your whole life in a farm, you can’t avoid seein’ somethin’ like that!” Applejack replied and smirked, ”Me and Big Mac take potty breaks in the woods all the time! When somepony pees while you’re around, it’s just a sign of affection!”

She turned her head towards Big Mac, ”Sometimes Mac just turns his back away from me and starts hosing the ground!”

”What?!!” Twilight yelped in shock as Big Mac blushed nervously.

”Ah… Ah thought you weren’t watching!” Mac stammered, Applejack smirking at his reply.

”Hey, we’re Apples, remember!” she cracked, ”We ain’t closet pervs, we do it as openly as it gets!”

”Well, that explains everything…” Twilight mumbled and looked at his brother, ”Are you done yet?”

Applejack followed suit, turning her head back to the show where Shining’s stream was slowing down to a trickle. He sighed in relief and gave his precious member a couple of hard shakes to get the last drops off, making Twilight’s eyes go wide.

”Atta boy! Shake it for momma!” AJ hollered while giving jerking motions with her hoof. Even Big Mac glanced curiously towards Shining's direction as if checking if his flopping thing was bigger than his.

”Ok, that was something I didn’t need to see…” Twilight looked away awkwardly, as Shining finished and kicked off the tree, his member twitching on its own as it retracted into his barrel.

”Whew, that felt good!” He sighed in relief, turning towards others, ”Sorry about that, guys! My bladder always gets filled up during sex!”

”None taken, sugarcube!” AJ replied and winked at Twilight, ”Your sis here enjoyed that a lot, ya know!”

”Wha- NO! I-I DIDN’T!” Twilight protested and blushed, while Applejack laughed her head off. She was starting to lose her mood if this went on!

”Yeah, sure!” She chuckled and turned towards Mac, wanting to get going what they had started, ”Ah reckon’ you still want what Twilight here was havin’?”

”Eee-nnnope!” Big Mac replied, thinking Applejack was referring to urine. He might have enjoyed watching his sister pee, but by Celestia, he didn’t want to get involved in pee drinking!

”Mah pussy juice, that is!” AJ added, rolling her eyes at Mac.

”Oh… Eeyup!”

”Good!” AJ rose up on the blanket, ”Let’s get started then!”

-THE END-
