Craving Big Mac

Twilight was nervous.

It was Tuesday. And it was almost lunch time. And she knew what that meant.

She had sent Spike away on a lengthy errand. She would have the place to herself for a few hours. She paced around the library for several laps, periodically checking out the window. She finished her third cup of tea. No sign yet. This would not do. She poured her fourth cup.

A hobby of hers that she enjoyed from time to time was building model ships. It was a good way to pass the time, other than reading of course. She opened a new kit that she had just bought a few days ago. She laid out the pieces on the bedside table. She had to push aside the other items she had been hoping to use sooner rather than later. She began reading the instructions for the model.

"Insert rod A into slot B... Hehe!" She giggled to herself, and then, immediately hated herself for finding such immature humor funny. Clearly her mind was elsewhere. She assembled the hull of the model, piecing it together with some model cement adhesive. It had a sort of hypnotic, calming effect. All her focus and attention was on the task at hoof. Her whole world shrunk down to the tabletop. Following each step one at a time. It was like checking off items on a check list, another thing she enjoyed immensely. It was the sort of thing that validated her hard work and gave concrete evidence to her diligent progress. She began making up a little ditty in her head as she worked.

Piece by piece, gluing it together.
A model ship, following instructions step by step.
Making the adhesive set nicely.
A great outlet for my pep.
I'm making a mooooodel shiiip!

She finished drinking another cup of tea. Tea was good for her nerves, she decided. She filled another cup.

KNOCK KNOCK

Twilight jumped at the noise. Her magic dropped what she was doing. She got up and quickly scurried over to the door. She cracked it open and looked outside. Big Mac looked in at her, a shy smile on his face. Twilight nervously looked over his shoulder behind him, scanning the area of town.

"Were you followed?" She whispered. He just shook his head 'no'. Twilight threw open the door, grabbing him by his wooden yoke and yanking him inside. The small purple unicorn had an unusual amount of strength when it came to moving the large red earth pony. She pulled the windows' blinds with her magic and quickly affixed the 'closed' sign to the door and locked it shut. She whirled around on the heel of her hoof and wrapped her hooves around him, pulling him into a deep, passionate kiss.

Each of them took great pains to ensure that Big Mac's sister, Applejack, did not find out about their... little meetings. In a population where females outnumbered the males nine to one, he was a hot commodity. Applejack hardly ever let him leave the farm. There was no knowing when some hot-to-trot town filly in heat might just jump him out of wild, unbridled desire.

Twilight believed deep down, the backwards farmpony sought to keep the stallion for herself. But no matter. She released herself from him just long enough to levitate the heavy work yoke from off his broad frame. She cast it aside and locked lips with him once more.

AJ would raise all sorts of hell if ever she caught him with any of her close friends. Not just him, but Twilight would be in for quite the pounding as well.

But now that she had him here, safe in her keeping, Twilight desired an entirely different kind of pounding from the scarlet workhorse. He slipped his head down from her face, planting kissed along her neck. She grinned with joy... and ticklishness, as he moved back up, nibbling gently on her ear.

"Mmm, come on. Quit teasing me." Twilight moaned. She leaned backwards, pulling him on to her as she fell backwards onto the floor. She laid on the floor, pulling him by his short, blonde mane down to her for another kiss. She pulled his hind end down with her legs wrapping around his midsection. She made her intentions quite clear. But Mac would not be dissuaded from being a gentleman.

"The bed?" He suggested. Twilight huffed momentarily, having to wait even just another minute longer. But she quickly scurried up the stairs to her bedroom with Big Mac right behind her. She flopped onto the bed. She spun around sitting up on it, pulling him into another kiss. Her embraced her and kissed her deeply again.

He pulled away from her kiss and gently leaned her back onto the bed. She sucked in a deep breath, anticipating him to take her right there. Instead, he kissed her again on her neck, giving her a little lick. He ran his tongue down her body, over her excited fur. He took tiny steps away from her, backing up as his tongue made a zigzag line to her belly.

"Hmm!" She bucked her hips reflexively, trying to drive him into her even faster. She was a mare possessed. "Mmm come on!" She squirmed underneath him. He gently placed a hoof on her writhing form, stilling her as his head slipped between her legs. She moaned in pleasure as his practiced tongue slipped between her hot folds. He lapped along the length of her slit and pushed into her hot entrance, gaining a measure of depth before sliding up to her little love nub, standing hard and demanding at attention.

He had enough familiarity with the mare to not engage her clitoris directly. Instead, he deftly maneuvered to either side of it, attending to her tender lips and also her sensitive inner thighs. But always, deliberately avoiding the one spot that would send her over the top. Her horn glowed. She grabbed his head with her magic. She pulled him and mashed his face into her, to use him for her pleasure. He resisted, pushing away with his strong legs. He was going to do this right. The way she needed, even if it wasn't what she thought she wanted at the moment.

In a burst of strength, he pulled himself away from her powerful, if unfocused, magical grasp. He thrusted himself forward, sliding his stallionhood along her hot sex. It was enough to shake her spell. But just as an insurance, he slid himself up along her body to take her horn into his mouth.

He realized the symbolism in taking a unicorn's horn into his mouth. But this was a mare after all. It didn't matter what the others said, or what it felt like. He just did what felt right. What felt good. He sucked on her horn in his mouth. He worked his long tongue over the tender ridges of her as he imagined he would like to be pleasured. It was hard to escape the analogy, but he press onward. Twilight certainly seemed to enjoy it. Her magic was completely defused.

Indeed, Big Macintosh was a hot commodity. Not the least of which, him being outnumbered by the vast majority of mares. But there was the odd stallion whose barn doors swung the other way whom fancied him as well. Mac tried to keep his thoughts from entertaining such individuals as he pleasured the current protrusion in his mouth.

His head bobbed up and down. His tongue did a dance along her length, swirling across the ridges of her spiral. Twilight, for her part, could barely breath under the ministrations of his savant-level expertise. Her eyes were screwed into an intense wince as she felt herself getting closer.

"OoohOOHHH AHHH!" Twilight moaned as she felt herself wracked with her horngasm. Big Mac tasted the familiar sensation as she came in his mouth. He knew a magic 'horngasm' tasted special. It was a sort of metallic, copper taste that washed over his taste buds, like licking a battery, before evaporating into nothing. It left a sort of o-zone smell in his nose before vanishing completely.

She bucked her hot pussy against his stallionhood. His length slid along the outside of her sex, grinding into her love nub as well, her heat radiating into his crotch. He needed little other prompting.

He slid his rigid shaft to the base of her folds, which were eagerly spreading around their welcome guest. His sensitive tip came to rest at her velvety pussy entrance. She wiggled, only slightly, beneath him, in an effort to gain a fraction of an inch of him inside of her. He needed no further persuading.

It was not their first time together. At which time they each needed to go slowly to accommodate one another. This time however, he slid himself forward into her in a practiced motion, filling her completely. Still, even though it was not Twilight's first time 'intercoursing' with Big Mac, and no matter what she had done before, she was always caught by surprise by that first, filling, penetration.

Sometimes Twilight would be on top. Other time she would use her magic more. Sometimes she played the submissive role. But every time, that first, filling, thrust, took her to that same surprised place in her psyche. Her mind and body was sent reeling at the flood of pleasure coursing through her.

This time though, it had been some time since their last encounter. Several weeks even, what with AJ's growing suspicions.
And for his part, Mac refused to 'take care of himself' at the farm. It was 'a waste' he decided, to spill one's self upon the ground. He felt Twilight's warmth around his member, spurring him forward, increasing his pace. His blood rushed from his cognitive brain to a different head, driving him to thrust harder and faster. He vaguely remembered something about trying to be a gentleman. But all those annoying thoughts faded into the background of the sensations he was feeling, and the moans of the mare under him.

He felt her clenching marehood gripping him, as though trying to suck him deeper into herself. The sensation was almost too much for him to bear. His response was immediate. As he thrusted faster, he could feel himself approaching the point-of-no-return. Twilight was likewise nearing her climax. He pulled out before it was too late. Twilight felt disappointed at the loss and at the missed opportunity to cum with her secret lover. But he returned swiftly, pressing his tip against her back door instead.

"Ooh, how kinky..." She cooed. She had had him in her tight buttocks once or twice before, and learned quickly from the folly of her first-time over-eagerness. "Use some of the lube this time please." She instructed. He grabbed the tube from the table, squeezing a liberal amount into his hoof before casting it aside and running it over the length of his throbbing member.

Her pressed his tip back against her, taking grip of her thighs for leverage. He slipped inside her with relative ease, much to his surprise.

Twilight had felt him press against her taught butt hole, only to slip upwards, back into her vagina. It mattered little to her. She was off of her cycle, and unable to conceive at that time anyway. Besides it just felt sooo good!

Big Mac resumed his thrusting, feeling free of any responsibility of restraint to cum in what he thought was her ass. Twilight could feel him swelling inside her. He was getting close. Her own plateau pushed back to the cliff! She was about to go over, about to cum!

"Um, Twi?"

Twilight felt him stop moving. WHY would he stop MOVING? She was so close! Just THRUST a couple more times!

"NRGGG What?" She asked, frustrated.

"I'm uh, I'm stuck." He said nervously.

"Just push harder!" She ordered, her need driving her desire.

"No, I mean..." He tried to pull his hoof off of her hip, pulling her fur and skin.

"OW! What the hay!" She yelped, looking down at his hoof, still attached to her flank. She tried to pull his hoof off of her, but it was solidly connected to her by some kind of... "OH horse apples!" She muttered, as she searched the floor for the tube of...

"Oh no..." She whispered, levitating the tube of 'lubricant' in front of her. "Oh no." It was the model super glue! Big Mac's eyes went wide, reading the label. He tried to pull himself from out of... herself. But to no avail. He was solidly connected.

"Binds flesh instantly." Twilight grimly recited off the label. He looked at her, unsure of what to do next. The seriousness of the situations was instant sobriety to their passion-addled minds.

"What do we do now?" Was all Big Mac could ask.

"We need... we need some kind of solvent..." She said, checking the label of the glue again. "Which can be ordered and delivered within four to six weeks..." She said, her voice full of dread. Big Mac could feel himself shrinking, attempting to retreat into... himself. But it was glued firmly in place inside of Twilight.

"So... what do we do now?" He repeated. Twilight felt strange, underneath him, her legs were still a-splayed. But there was little she could do to change her position.

"We need to get downstairs to my lab... somehow.. We can try to synthesize a solvent there!" She looked up at him from her position under him. She looked behind her and levitated the wooden yoke back around Mac's neck. She reached up with her hooves, trying to pull herself up to him. Her body shifted a bit, pulling on his now, very tender, stallion bits. Big Mac yelped. He made a noise that she had never, in all her years, had ever heard a stallion make.

"Ooh, sorry." She cringed. She wrapped her hind legs around his body, lifting herself up off the bed just long enough to strip the bed with her magic. She tied the sheet around them tightly, making a sling for herself, still impaled on him, and attached to his underside.

"There. You should be able to walk now." She instructed. Mac lifted himself up off of her and the bed. He could handle the weight just fine, even with one of his hooves bound by glue to her hip, but the weight was bulky, and positioned poorly. It was very awkward to stand. Especially with him... still in her.

Carefully, he took a couple steps away from the bed. She was strapped securely to his underside. If it was one thing Twilight knew, it was knots. Mac remembered fondly his first time finding out about that particular skill of hers. It made him swell slightly again inside her.

"Whoa, easy there! We have a real problem to deal with here first." She scolded. She couldn't deny that it still felt good. She was still frustrated from being denied her climax earlier. She wanted nothing more than for this ordeal to be over with so they could resume their rutting. First things first. "Okay, let's head downstairs.

Big Mac made his way over to the staircase. Twilight let her head hang back, looking in front of them, at the world upside down. It was only a dozen steps. But from her angle, it looked terrifying. Her whole body tensed up as he took the first step. It was a small, hop of a step with his lone fore hoof. She began sweating as he slowly, deliberately, took each step one at a time. Despite three legs to catch himself with if he stumbled, a misstep in this situation would be disastrous. The idea of Twilight slipping loose, her fall being arrested only by her being attached to his poor... she shuddered. She remembered the horrible yelp from earlier, and checked once again that the knot was indeed still tightly secured.

Pressed against his underside, she could feel his heart racing. It was almost as fast as hers. Twilight clenched her eyes. Now only trying to count the steps until the bottom. She couldn't focus long enough to make it to twelve. But before she knew it, his body leveled out. She opened his eyes, they were safe on the lower floor. Now that the 'practice' was over, it would be time for the long staircase leading down to her laboratory basement.

But Twilight felt a more pressing issue. She cursed herself for drinking so much tea earlier. Aside from it being her usual post-coital activity, all the excitement and jostling, she knew she wouldn't be able to hold it any longer.

"Um, Mac?" She whimpered. He halted his approach to the lab staircase door. He looked down at her between his legs. "Um, I don't know how to say this, and I have even less of an idea of how it's even going to work but..."

"... I need to use the little filly's room." She said, nearly in tears. Big Mac couldn't react. Today was already too surreal. He just kept his calm.

"Can't wait?" He asked. She just shook her head.

"It's... I really need to, pretty bad." She said.

"It's- it's okay." He comforted her. "Let's just... try to deal with this." He turned and walked into her restroom. Inside, they each just stared at her humble commode, and then at themselves. How the hell was this going to work?

Mac was the first to attempt a solution. He turned his backside to the porcelain bowl, trying to have her... back end hovering roughly over it. But there wasn't enough space in the small half-bathroom. Also the position would make a much larger mess than she was yet ready to accept.

"What if..." Twilight craned her head around his frame to get a look at the toilet. "Want if... you sit down, and I sit on your lap?" She suggested.

Big Mac looked behind himself, considering the position. He shrugged. It was as good an idea as any they were going to be able to do. He backed up and squatted slightly before pushing off the floor with his foreleg, plopping himself onto the seat, pulling Twilight upright in front of him. She sat there straddling him, facing the back of the toilet. She lifted the sheet up from around her waist as so to not soil it.

She was still impaled on him inside her, but she would still be able to go. Her legs were resting on top of his, creating a funnel that led down between her crotch and his legs. It should serve to direct her... flow... to the bowl under them. She hugged him, her head now level with his. She gave him a soft kiss.

"Thank you for... this. Helping I mean. And... understanding." She whispered. He just smiled back, shrugging. It was the sort of 'shit happens' shrug you give when you just accept the bizarre circumstances beyond your control. She was incredibly nervous about this. Twilight closed her eyes, trying to relax.

Mac just sat there as still as possible, trying to not distract her. But it couldn't be helped. She could feel the warmth of his legs under hers. She could feel his pulse, throbbing inside her. She was very aware of the other pony in the room. Twilight took several deep breaths. Each time, trying to just... let go.

After a couple quiet moments, Big Mac felt a tiny stream of warmth on his abdomen. Twilight breathed out, she relaxed. He looked down between them. Her small, yellow stream flowed from out of her stretched pussy lips, trickling onto the base of his shaft and his belly, before running down around the sides of his cock, between her legs and dripping onto his balls. The warm sensation of her pee on his nuts was relaxing and... strangely arousing.

Twilight relaxed more easily now, having finally started. She had been holding it for some time. Her tiny stream rapidly surged into a powerful gushing. The built up pressure behind it finally released. She was very much spraying on him! She paid it no mind, she simply relished in the relief. The room filled with the thick, musky aroma of her piss.

"Mmmnn." She moaned in base pleasure of relieving herself after so long. Mac simply sat there as her torrent of hot urine sprayed onto him with force. It splashed off his crotch, soaking her hips and his hoof, still stuck to her hip. He felt her spray on his hoof and instinctively tried to pull it away in reaction. It was still attached to her, but- it started to give slightly.

"Umm, Twi?" Mac asked of her attention. She was lost momentarily in her urinary bliss. She half-opened her eyes.

"Hmm?" She asked.

"Look." He said nodding to his hoof as it began to slightly come unstuck from her dampening fur. Twilight's eyes lit up!

"That's it!" She said.

"What is?" He asked.

"A solvent! Uric Acid! It's one of the components of... pee." She explained, adjusting herself on him, to try to redirect her flow. Her stream turned and now was aggressively soaking his hoof on her hip. Sure enough, it started to peel away from her body. Her stream slowly dribbled to a stop by the time he manage to completely wriggle his hoof free of her fur.

"Ha! Success!" She beamed. But now there was still the matter of... him... in her. Even if she was not already out of... her solvent... there would be the matter of delivery to the... affected area. She had another brainstorm. She levitated a cup over to the bathroom sink, filling it with water.

"Here! Drink up!" She held it between them. He looked at her a bit strangely. She loved him, but he could be so thick sometimes. Not that she minded his thickness sometimes.

"Um... what for? I'm, er, not really thirsty." He asked. She smiled weakly.

"I- I need you to apply some... solvent... to the other... affected area." She tried to explain. He took the cup, pouring it into her lap. She took the cup from him, re-filling it. "No, I need you to drink it." She gave him the cup again. He drank it and still looked like he didn't get it. "I- I need you to pee in me." She said, her voice shrinking into a Fluttershy whisper.

"Hmm?" He said, not quite hearing her, even at their exceptionally close proximity.

"I- need you to pee inside me." She finally said plainly. "It's the only way we're going to be able to get... un-stuck." She explained, filling another cup. He took it hesitantly, drinking it again. She quickly refilled it. "Just keep drinking until you need to... go."

"Twi, I- I do need to go." He said.

"Oh okay." she said, sitting back, adjusting herself and closing her eyes. "Go ahead." She smiled, rubbing her tummy expectantly.

"Um, it's just that..." He started to say.

"Yes?" She asked, frustrated, opening her eyes again.

"I don't know if I can." He said finally. Twilight sighed and grabbed the cup of water.

"Then keep drinking until you can!" She ordered.

Mac sat there with Twilight in his lap, his penis still glued inside her. He drank cup after cup of water. He felt so full! He already had to pee terribly. Her sitting there on his bladder just made it worse. And now all this water?! He felt like he was going to burst! But something inside him was just not letting it happen.

"Come on! It's been like fifteen cups now!" She whined.

"Seventeen." He corrected, feeling very acutely aware of the amount.

"Seventeen! How can you not have to go!?" She moaned.

"I do!" He moaned in agony. "I'm just, I dunno. I'm nervous!" He cried.

"Oh. I'm sorry." Twilight apologized. She leaned forward, hugging him. She felt so bad about this whole thing. She kissed him softly on the cheek. She took his hoof in hers.

And then she surreptitiously put it in the sink full of warm water. She'd hoped the classic prank's nocturnal effect would apply here. She had been waiting here on him so long now she nearly had to pee again, herself.

As Big Mac felt his hoof become submerged in the warm basin of water, he could feel the knot in his belly let go. He could feel the relief as he began to pee inside of Twilight. And not just a little.

Twilight immediately felt the rush of new warmth inside her tummy. She released him from her sneaky hug, and leaned back, arching her back, and placing her hooves on his knees behind her, stretching her abdomen. Big Mac's pent-up bladder poured into her pliable vagina, quickly filling it.

Twilight groaned as she felt her marehood being stretched. It continued to fill with his hot piss. She could see her belly inflating. She'd had some idea beforehand what this would feel like, but nothing could have prepared her for this!

As she watched her stomach continue to stretch, and began to regret force-feeding him nearly a gallon of water. She could feel something beginning to give. She could feel the walls of her pussy began to stretch away from his shaft as the pressure continued to build, and the acidic urine did it's work dissolving the glue. Although there was still a lot of shaft and vagina to go. But then, she felt something else give way as well.

Her pussy stretched to it's limit! Under the pressure, Twilight's cervix parted just slightly. Mac's warm pee flooded her stretchy womb. The sudden drop in resistance only helped him to finish emptying his bladder. Twilight could only look at herself in abject shock. She looked like she was nearly five months pregnant! With a final grunt, Mac sighed in relief, having finally finished emptying himself inside of her.

Twi shifted herself nervously on top of his member. She could feel the warm liquid sloshing around a bit inside her stretched cavity. She could feel her pussy continuing to un-glue, and open out around his shaft. It wouldn't be long now until they were released from one another.

Twilight rocked her hips, trying to expedite the process. It only served to stimulate the stallion. He felt his erection growing inside her as she moved around, grinding on top of him. His new erection continued to grow into her, pushing the volume of her inner space to a critical point! Twilight felt like she was going to pop! The pressure was too much! She cried out!

Finally, the last bit of glue dissolved! A torrent of Mac's urine burst from it's crowded confines. A golden waterfall erupted out from her pussy around his liberated member. Big Mac, now fully aroused, and ready to finally finish what he started, suddenly grabbed her hips and began bucking wildly up into her. With each bounce of her on his lap, another gush of his piss spurted out or her pussy on him and everything around them. His piss splashed everywhere with each wet slap of her hips slamming down on his. Likewise, as she came crashing down each time, she mashed her pussy into his crotch, grinding her clit against his pubic bone.

"Ngg! ngg! gah! AH!" She slammed down a final time, squeezing his sides her her legs, squeezing his dick with her clenching pussy as her belated orgasm finally overtook her. The sensation put him over the top as she felt him cumming inside her in powerful bursts. His cum flooded her insides, mixing with her mare cum and his piss in a great confluence of their fluids.

He collapsed forward. It was a long day for both of them. He had used up the last of his earth pony stamina in a final adrenaline-fueled bucking. The two of them stumbled onto the tile floor, panting in post-coital bliss... and several other liquids. The entire room reeked of sex and urine.

BOOM!

The pair looked up to the door being kicked in. The orange farm pony had finally tracked down the whereabouts of her missing brother. He had been gone for hours.

But now, well, she rather wished she hadn't found him.
