Roleplaying-

“Twilight, I’m... I’m not sure about this...” The changeling kicked a holed hoof as the unicorn opposite him grinned deviously.

“Relax, silly filly. Since Chrysalis bit the dust, you guys are all accepted, right? At least... You know... The ones that aren’t all evil.”

“Well, yeah, but... I don’t know how all that... Other stuff... Works...” He flushed and looked down at the ground.

“Alright. If you don’t wanna do it, then I’ll go get somepony else...”

“N-no! I’ll do it! I promise! Just... Just gimme...” He furrowed his brow and concentrated. He had seen him before... Once... Concentrating hard, the green flare of magic roiled around his hoofs, lanced over his body... In a bright flash of green changeling magic, he shifted from the insect-like, swiss-cheese pony-esque form into none other than...

“Well hello there, Big Mac.” Twilight’s face flushed as the intimidating earth pony filled her bedroom. “What... What, uh... Brings you around to my library?” She was obviously smitten, and the changeling felt his shifted lips curl into a smile.

“Oh, nothing... Just thought I’d stop by to... Uuh... What do you have here, books?”

“No, no, no!” Twilight stomped a hoof and glowered at the big horse in front of her. “Big Macintosh isn’t like that at all! Ugh, you’re doing it wrong!” She huffed and trotted over to a bedside table, pulling a drawer open with a thin trickle of magic. She withdrew a photo and waved it in front of his face with a frown. “See the disinterested, almost vacant expression? The strong way he holds his head high? And he hardly ever speaks in full sentences! Get it right!” She tossed the picture aside. “Honestly, what sort of changeling are you?”

“H-hey, this is hardly fair...”

“And his voice is deeper!”

“Ugh... Fine...” He focused on some small, minor changes to physique, vocal cords, diaphragm... “There, that better?” His voice was markedly deeper, his face a little more soft instead of purely hard-set.

“Getting there... Come on, try saying something. I know he usually only answers in the affirmative or the negative... Sort of in a country way. Uuh... Here...” She stepped closer, wearing a wide smile. “Heya Big Mac! Did you stop by to pick up the new farmer’s almanac?” The changeling blinked.

“Eeyup.” Twilight swooned so hard she nearly fell over.

“Ooh... Oh my, that was perfect... Right then.” She cleared her throat, getting professional. “I’m sorry, Mr. Macintosh, but I’m afraid I don’t have the new almanac in just yet. I tell ya, the folks over in Trottingham really struggle to get the new ones out to the small towns... I can write them again, but I don’t think it’ll be here for another week or so. Is that okay?” He fought a grin as he stepped closer.

“Nnope.” Twilight blinked and furrowed her brow.

“Wh-what do you mean?” She asked softly. “I have... Some older entries, if those will help?”

“Nnope.”

“Aah, here... Horticulture in Equestria?”

“Nnope.”

“Apple Bi-Weekly?”

“Nnope.”

“Greenhoof Gardener Monthly?”

“Nnope.” Twilight finally huffed and stomped a hoof.

“Then what did you come here for? Surely, it wasn’t just for some conversation, or maybe to see me again?” Macintosh grinned.

“Eeyup.”

“Wh-... Really?” Twilight flustered, flushing even brighter. The purple coat of fur on her cheeks had darkened quite a bit by now.

“Eeyup.” He stepped closer, on big clydesdale hoof making the floorboards of the ‘Tree’ house groan under his substantial weight.

“Well... What do you want to talk about?” She waved a hoof about. “I’m hardly more than your average, mousy, librarian pony... I mean, I like books and... Reading...” She glanced about, seemingly frustrated with herself. “Do you want to talk about books?”

“Nnope...”

“Apples?”

“Nnope.”

“Wh-... Well... We can talk about... Me?”

“Eeyup.” Twilight kicked the floor self-consciously.

“What about me? Do you want to know about my history?”

“Nnope.” He was getting tired of this. Then again, the slow approach to what the unicorn really wanted was certainly going to make for one hell of a climax...

“My cutie mark?” He had to answer something other than his previous two answers to this one. He raised a hoof and shook it side-to-side slowly.

“Close.”

“Hmm... Close to my cutie mark but not... Wait, do you mean my flank?!” Macintosh grinned. NOW they were getting somewhere.

“Eeyup.” Twilight’s chest heaved as he stepped closer once more.

“What about my flank?” She whimpered softly. He stepped closer once more, his breath surely washing over her horn now. He could see her gnaw on her lower lip. “D-... Do you want to talk about... How non-muscular or un-shapely it is?”

“Nnope.” He kind of popped his lips, sending a breath across her horn. She shivered. SO damn cute...

“How... Thin and delicate it is?”

“Nnope.”

“How I like a colt to smack me with his hoof when he mounts me?” Okay. THAT was out of nowhere! Twilight looked up at him, those magnificent eyes filled with every emotion from anticipation to lust and everything inbetween. Swallowing past the lump in his throat, the changeling nodded.

“Eeyu-” Cut off by Twilight’s lips, Macintosh groaned into the kiss, his mouth soon filled with Twilight’s greedy tongue. Shivering, Macintosh felt the tingle rise in his nethers. That was one part he hadn’t thought about... How big was the red colt? Not the sort of thing you walk up to a pony and ask straightaway... Especially when you’re a changeling... His thoughts wandered as he shifted his genitalia, guessing at the length and girth. It was only when Twilight patted his cheek with a hoof did he realize the kiss was over.

“Helloooooo. Macintosh. Forget what we were doing, here?” She teased, lips curled into a devious grin.

“N-nope...” He stuttered, finally settling on thick and long. Not like she was going to complain with THAT... Unless it hurt her? Taking a bit off the girth, he shook his head and smiled down at her.

“Now... Where were we? Oh... My flank...” Twilight pointedly turned about, thrusting her rear out at him. The scent hit his nostrils like a train carrying naught but bricks and a few boulders short of a quarry. Grunting softly, he inhaled the scent of her tail, of her arousal. His hoofs shifted on the floorboards. “What’sa matter, big guy?” She teased, whipping her tail around to gently lash at his neck. The movement exposed her center for a brief moment, the puffy lips flared and glistening. “Forget to breathe?”

“E-... Eeyup...” Shivering, Big Mac just had to itch the scratch... Lifting a rear leg, he nudged the head of his distended cock, fighting the urge to moan as it bobbed underneath him. Twilight smiled and sniffed the air, paused, then sniffed again. Her eyes closed as she inhaled the elusive scent.

“Hmm... Mac, are you wearing musk?”

“N-nope...” He whimpered.

“Have you showered today, then?”

“Eeyup...” What a silly question.

“Oh... Then what I’m smelling has to be...” Big Mac blinked. Twilight was suddenly against his side, dipping her head low and inhaling the air directly against his unsheathed prick. “Oh my...” Her breath washed over the pulsing shaft, radiating through his entire body. Hesitantly, her tongue slid out to brush over the tip.

“Aah! Hey!” Suddenly, Big Mac was lifted, Twilight’s horn glowing purple as she easily hefted his weight. His back pressed to the wall, hooves scrabbling against the floor as Twilight pressed against his front, standing on her own two rear legs. She hardly came up to his neck.

“Relax, Macintosh... Let me get you warmed up.” She nuzzled into the fur on his chest, hooves running down to his flank. Her mouth left a damp trail in his fur as she slid lower, her tongue spreading the darkness over his red coat. “Do you want me to rub your tummy?” She asked. Breathlessly, Macintosh replied.

“Nnope...”

“How about your flank?”

“Nnop-pe...” He was stuttering. This was bad.

“Then... What about... These?” Her hoof laid against his swollen testicles, lifting the twin orbs gently. Sagging against the wall, Macintosh couldn’t even speak. He just nodded. Twilight grinned and opened her mouth, breath washing over his head. “I think...” Celestia damn it, that BREATH... “I’ll skip the pleasantries.” Eyes snapped open as Macintosh looked down at her, her muzzle opening wide to take in the thick shaft. That first embrace inside her hot mouth made Macintosh nearly collapse. He pushed his hips forward, slid another inch into her mouth. She released him, pulling back with a breath.

“Pwah! Easy, there, big guy... Don’t wanna choke me now, do ya?” She teased. Macintosh whimpered and shook his head. Then he paused. Thinking on it, he nodded, grinning down at Twilight. “Oh! Well, alrighty then... Let’s do it!” She licked her lips and opened wide once more, grunting as she took all of him she could handle into her hungry mouth.

“Aah!” Macintosh cried out as he felt her throat open for him, slide down about half the length of his formidable cock. She couldn’t handle any more after that, and with a delightfully erotic gagging noise, pulled out.

“Guh! Woah!” Her cheeks were almost crimson now. “That was... *Cough* Aahn! Let’s do it again!” And she did, hardly giving him a moment to adjust before her mouth wrapped around his cock once more.

“Twi!” He gasped. “Gonna... Gonna...”

“Oh no you don’t.” She pulled away, horn glowing as she squeezed him off. “Not inside my mouth, anyways.” He was filled to the brim, ready to explode at the slightest touch. She gave him that touch, but he couldn’t... Couldn’t do it...

“Oowwwww...” He cooed, feeling the base of his cock fill with pent-up release, moments form releasing. He flexed and writhed, but Twilight’s magic was too strong. Slowly, it receded, almost painfully.

“Come on, big guy.” She turned around, swishing her tail aside and thrusting her flank out to him. He could see all of it... Her tight pucker, her flared sex, the dampness of her purple fur... He fell forward onto his hooves with a grin. Time to get some payback on the purple unicorn. Grasping her tail in his teeth, he lifted a hoof and whacked her nice and firm. The powerful blow staggered her legs, made her cry out, half from pain half from pleasure.

“Aahn!” Twilight shivered underneath him, and he could have sworn he smelled a fresh wave of arousal. Smiling, Macintosh jumped up onto her back, hooves almost reaching the floor. Indeed, when she dropped her hips, he could... Twilight fit underneath him easily, and he grinned as a thread of magic pressed his head against her puffy sex. No more nice changeling. Rough as can be, he pushed his hips forward, felt the flared tip spread her apart, slide in, spear the quivering mare on his formidable cock.

“F-fuck...” Twilight grunted, her breath short and fast. “Feels good... Harder!” She groaned. Not one to deny, the changeling Big Mac pressed deeper, sliding almost all of his engorged member into her. She took it all. ALL of it. Down to the shaft. Twilight coughed. He HAD to be hitting something inside of her. Sliding out to the tip, Macintosh had to take a few steps until he was adjusted. Feeling comfy once more, he slid back in, pulsing deep into her. His belly met her flank with a smack, the kind that made Twilight groan again. Pulling back, moving in, back, in, out, in... They were soon lost in the passion. Mac was riding her so hard, his coat was soon lathered with sweat, his barrel-like chest heaving with the exertion. Each firm impact made him grunt, his breath washing over Twilight’s horn. That seemed to make her want it more. Tongue lolling out of her mouth, Twilight begged for more.

“Harder!” Twilight panted. “Harder!” Macintosh grunted. “HARDER! AAHN! CELESTIAAAAAAAA!” Back arching powerfully, the slight mare nearly Lifted Big Mac with the rough motion, her walls pulsing and quivering around the shaft buried deep inside of her. His ears flicked, caught the sound of... Splattering liquid? A quick glance down to the floorboards betrayed Twilight was a squirter. Quivering and moaning, she flexed around him once more, her head turning just enough to glance up at him.

“K-keep going... You can cum inside of me...” She whimpered. SO DAMN CUTE. Unable to resist, Macintosh took her up on the offer and started thrusting again, taking it a little easier so he could focus on his own pleasure. And there was quite a bit of it... Groaning, Macintosh plunged deep, flexed, hit parts of her walls that weren’t normally touched, even during normal intercourse.

“AAHN!” She grunted. “That’s... Th-that’s my G-spot!” She whimpered. Big Mac grinned and hit it again, making Twilight grunt and almost let loose a scream. He plunged in and hit it once more. “FUCK!” She cried out, taking a breath as another gush of liquid poured out onto the floorboards. The wet, erotic spattering was almost too much to resist. That, and the way she was flexing around him...

“EEYUP!” Panting, Mac let loose with all the pent-up cum he had been holding back, pouring stream after stream of hot release deep into Twilight’s quivering marehood. Together, the two fell onto their sides, the floor shuddering under Big Mac’s weight. They could hardly do anything other than pant and lay there. Twilight came around first, wriggling her hips as she crawled forward. Slowly, Mac slid out, his spent cock quickly returning to it’s sheath.

“Th... Thank you...” Twilight panted. She wasn’t addressing Big Mac anymore, but the changeling. Shifting back to his normal form, the changeling smiled and nodded. “No, really... I think you... Heh... Nailed it...” She quivered and shifted her hips against him, tucking back against his form. Hooves looping around her neck, the changeling whispered into Twilight’s ear.

“Anytime...”

“Really? Like...” She gnawed a lip. “Right now?” Big Mac returned in a flash of green magic, smiling.

“Eeyup.”
