"ACHOO!"

"How does a unicorn even get the feather flu?" Rainbow Dash asked as she fetched a box of tissues for her sick friend.

"I'm not sure, but I'm pretty sure I know who gave it to me" Twilight commented as she blew her nose carefully. Dash was unsure of the meaning behind her friend's statement for a moment, but instantly went wide-eyed when it came to her. Putting on a sly grin, Dash leaned in a little closer and lidded her eyes.

"It was totally Thunderlane, wasn't it?" she asked, making Twilight's eyes go wide and her face change into a noticeable pink. Dash smiled at this and pointed at her friend teasingly. "Aha, I knew it!"

Twilight's ears drooped and she looked towards the floor. Dash just smirked further and leaned in, whispering into Twilight's ear.

"How good was he?"

Twilight only squeaked and leaned away from her, not wanting to give her the satisfaction of getting to her. Of course, if it weren't for Dash's constantly nudging further, then she probably would've gotten away with it. With a sigh, Twilight turned back and gave Dash a stern glare.

"You have to promise me you won't laugh" she demanded. Dash merely grinned and then nodded kindly. Twilight took a moment to think it over, then continued. "It was back during the hurricane thing" Twilight started before the screen transitioned properly into the flashback.

Twilight sat down by her device, carefully calculating the individual recordings that it picked up any time a pegasus flew by it. Across the way, however, was Thunderlane, Rainbow Dash, and Fluttershy. The trio of ponies were all carefully stretching their bodies out, taking in some unusual poses. Thunderlane was standing opposite the direction from the other two, but Twilight had a perfect view as he suddenly leaned up on top of his fore-hooves.

He kept on flapping his wings, trying to keep his balance, but that wasn't the thing Twilight was focusing on. Going red in the face, Twilight looked and saw a huge, black, raging horsecock flaring out from between Thunderlane's legs. She shouldn't have been staring at it, but yet, there was something keeping her from looking away. It looked as though it were only a little around 15 or so inches, but it was definitely thicker than what she thought they looked like. Some drool dripped from Twilight's mouth onto the nearby ground, and she felt herself getting warmer inside and out in the process.

Meanwhile, Rainbow Dash glanced around her shoulder and stopped with wide-eyes.

"Thunderlane!" she complained, stopping her stretching and pulling the other pegasus' body down by his flanks, both of their faces red. "Nobody wants to see that, dude!" she scolded angrily. Thunderlane merely blushed and then looked elsewhere, not wanting to make eye contact.

"Like I could even help it!" he defended, "You try keeping it cool when you're surrounded by this much ass!" he continued, getting a firm slap across his muzzle.

"Don't you go blaming us for anything, you're the one who popped it!" Dash argued as Thunderlane was still reeling. The black pegasus just took the moment to glare at her, then turned away with a huff and stormed off. Dash had to curse herself for looking longer than she wanted, but she simply wasn't going to let anything get in the way of breaking her record.

Twilight, however, wasn't so fortunate to be able to ignore any of that, and felt as though she needed to confront Thunderlane after everything was over.

Dash rolled on the floor, laughing her head off and pounding her hoof into the floor. Twilight scowled down at her friend, knowing fully-well that she was going to laugh at her, though desperately wishing she would've at least tried to laugh elsewhere.

"Okay, s-so come on, what happened after that?" Dash asked as she started to calm down, clutching her rib as her breathing started to regulate. Twilight just crossed her fore-hooves across her chest and looked out towards the window, choosing not to say so much as a word to her. Dash hopped up onto the bed and then smirked further. "Come on, Twi, don't be like that" she purred as she nuzzled the purple unicorn's neck. Twilight sighed and then pushed her friend away lightly.

"Anyway, I tracked down Thunderlane later on that day. Our schedule were free, so we decided to make a date for later that evening" Twilight stated solemnly as the blush started to fade. Dash, on the other hand, had a bored expression strewn across her face. She gestured with her hoof to continue, but Twilight refused to do so.

"What, was he like, bad at it or something?" she deadpanned, Twilight's blush creeping back up on her.

"R-Rainbow!" she whined, not wanting to put up with anymore, she just wanted to sleep this off and be done with it. But of course, Dash had other plans.

"Twilight, we both know I'm not gonna leave you alone until you tell me how things went. I dunno about any kinda scientific terms, but I'm pretty sure that telling me is the easier option" she told her. With a sigh, Twilight sat upright, closed her eyes, and started describing her evening. "Oh, and do me a favor and cut out the dinner or movie or whatever, and just tell me what you did at his house" Dash added a moment later. Twilight groaned and glared at her, but decided to do as she sais and get it over with.

Twilight and Thunderlane were both happily laughing outside of his house. After a lovely dinner at the local cafe, they managed to find out a lot about each other. They both really liked reading every now and again, had a little brother figure in their lives, and they had even had to deal with lots of really crazy situations.

"Oh, I've had so much fun tonight, Thunderlane" Twilight cooed as she stopped giggling.

"Well, the fun doesn't have to stop just here" Thunderlane told her, Twilight looking at him with a slightly awkward look in her eyes as she thought about what he was implying. "I mean, my little bro ain't here right now, and he won't be back until the end of the night and all" he added, wiggling his eyebrows at her.

"Well, I guess since you're being so nice and all, I may as well indulge myself a little" Twilight cooed, giving a surprisingly sexy giggle as the two headed right on into his house. It was certainly what one could expect from a stallion and his younger brother living under the same roof; messy, but with some things cleaned up here and there. Thunderlane lead Twilight to the back of the house, up towards his bedroom, then turned to find Twilight looking at him with a sultry, incredibly eager look in her eyes.

"Never would've thought you of all mares was so interested in something like this" Thunderlane chuckled, sitting on the edge of the bed with his hind legs spread and dangling off the sides. Twilight came up and nuzzled against his sheath, taking in the exciting, musky aroma of stallionhood with a smile on her face.

"Well, I must admit, I was a little curious after seeing you earlier today" she purred, looking up at him with that same, sultry gaze.

"Oh, you saw that?" he asked, chuckling awkwardly with a blush just barely visible from his dark coat.

"Yeah, and I have to admit, it's definitely something a mare could come to enjoy" Twilight chuckled, licking and and tracing her tongue around the base of his sheath slowly. Her hooves hefted up his balls gently, caressing them ever so sensually as the tip of his pitch-black member began to rise up out of his sheath as if Twilight were a snake charmer.

Thunderlane went and pulled her up on top of himself, lying down on the bed before Twilight went and turned, presenting her plump, purple booty with her tail going just underneath the line of her marehood. He could smell just how much she burned as she went and lowered herself down onto his muzzle, leaning down to lick and suck on the head of his cock a bit and admiring the way it practically shot straight out of his sheath.

The two exchanged glances before immediately 69-ing one another, Thunderlane burying his muzzle deep into her hot, juicy pussy as Twilight popped the head of his cock into her mouth. She suckled along the ridges of it, swirling her tongue all around the head as she started to bob her own head to take in more of his shaft. He was incredibly thick, making her strain her jaw just to try and get it to fit into her mouth more, but she managed to get it going just right without any teeth or anything getting in the way.

Thunderlane himself got to work rubbing along her luscious cheeks as he flailed his tongue around her insides, looking for that precious G-spot of hers as a single hoof rubbed along her crotch to try and coax her clit out. Twilight moaned out onto his shaft with a wide blush on her face, wanting to have him spear her with the big, hard, black cock she had in her mouth still. It was just so great a feeling, she went and got right up off of it, turning to face him, planting her lips against his as her dripping pussy grinded against his hard pole.

Thunderlane understood her right away and grabbed hold of her plush flanks, aiming and positioning himself just right before thrusting right on into her. She squealed at the sudden penetration, but moaned out his name sensually as she worked her hips back into his cock more until she felt him poking her cervix already. He drew back a little until he could get another good thrust right in, knocking the wind out of the brainy mare from his thickness alone.

Soon after that, he began thrusting in at an even, slow pace to help her get used to the feeling, watching her body adorably convulse every time he thrusted in, yet loved the feeling of being sucked back every time he tried to pull back. She was either incredibly tight, or he was simply too thick for her to really handle. Either way, he felt incredibly hot all over, the feeling of euphoric bliss washing right over him as he let out some moans in addition to Twilight's.

The only thing audible in the slightest was the sound of balls slapping against something wet, coupled with a pair of moans from a stallion and a mare together in the early evening hours. Twilight and Thunderlane wound up going at it for almost an hour before Twilight hadn't been able to take any more and her pussy suddenly clamped hard around him. She came hard all over his crotch with her juices exploding right out, and Thunderlane wound up being stuck in the spot he'd been in for some time. Eventually, he was able to pull out and stroke himself off before completely painting Twilight's entire back white with his seed, making her moan out from how hot and sticky her back suddenly felt.

Twilight looked Thunderlane right in the eye and they kissed once again, practically falling sleep in each other's embrace as they suddenly passed out.

"Wow..." Dash breathed, a blush on her face as she had been so casually hoofing herself off at the images formed in her head. "I knew the guy was something, but that was just awesome" she added, Twilight blushing and groaning over the memory.

"Yes, now that we've gotten over this, can you please just take care of me normally?" she asked, feeling rather annoyed. Dash just gave her a warm smile and ruffled her mane a little, smirking and giggling to herself.

"Sure thing, but maybe you can give me a try next time ya feel frisky" she said, slowly trotting away as Twilight started magically chucking pillows at the cyan Pegasus.

Author's Note

Just a nice little short I based off of this one image on Derpibooru. There isn't all that much sex involved, which is really weird considering I've made myself known as a clop artist, but I think it's cute.
