The only chapter

"Big Mac, can you come help me with this?" Applejack shouted to her brother, in the hope that he would come and help her set up for Apple Bloom's birthday party.

"Eeyup," he said unenthusiastically, and slowly returned to the room.

They moved around some furniture, blew up colored balloons, hung up streamers, set up Pin the Tail on the Pony, and put a pink tablecloth on the cake table. He set out pink cups and plates, and plastic silverware. When he was done he started to leave, on his way to take a big, fat, delicious nap.

"Oh, no you don't!" Applejack protested. "You have to help me with this party!"

Big Mac rolled his eyes, turned around and marched back into the room. He sat down next to the cake, swiped some frosting off, and licked it from his hoof.

He was not at all looking forward to the next few hours with a bunch of screaming, screeching, squealing, yakking, talking, giggling fillies. Ugh, he thought, here we go… chaos starts in five, four, three, two… and Apple Bloom came in, wearing her beautiful party dress with a brand new bow in her hair. She really did look pretty. Her eyes were sparkling, and Big Mac's heart filled up with love for his little sister.

Sweetie Belle was the first guest to arrive. Soon after she came, they all showed up at the same time: Snips, Snails, Babs, Dinky, Pip, and Twist, each one holding a brightly wrapped gift.

Just as he'd expected, the silence was shattered by the excited talkative fillies, who were, to Big Mac, a nightmare in his head.

The doorbell rang one more time and he got up to answer it: it was Scootaloo. Of course, Scootaloo. He hadn't even noticed she wasn't here.

She took off her purple helmet and shook her head. "Hi," she said with a smile.

"Eeyup." Big Mac stood aside so she could come in. She got off her scooter and leaned it against the side of the house and went in, setting her helmet on a chair.

She walked by Big Mac and melted into the crowd of fillies.

She smelled good. She smelled… different.

Big Mac had never really paid attention to her — at least not up until now. Something was different about her but he wasn't sure just what. He'd known her since she was just a baby. He'd watched her grow up — she was, after all, just like a little sister to him. Today, however, she was different.

Maybe it was the way she shook her head when she had taken off her helmet. Her short purple mane was tousled and glistened in the light. Her teeth were white and pearly. When she smiled she did this thing where she pressed her tongue against her teeth — maybe that was it? Maybe… She smelled so good. Whatever it was, he kept a close eye on her and began to look at her in a different light.

He watched her play; she was indeed growing up. She was getting tall. Her legs were long and her back legs muscular from pushing her scooter. The muscles underneath her fur quivered and twitched. Her wings were growing. They were becoming graceful and feathery instead of fuzzy little things.

Her purple mane had highlights of red, and her eyes were big and purple, adorned with long, curling lashes. Her body… her body was filling out very nicely. She was losing her baby plumpness and growing tall and thin, looking more like a mare than a filly. Her nipples were a little bigger too — soft, pink little pipettes that were just asking for attention. And her scent… oh, Celestia, did she smell good! He walked over to her and put a foreleg around her, like he often did, in a friendly gesture.

"Hey, kid," he said and was intoxicated with her scent.

"Hey," she replied.

She felt so good. It felt so right being next to her. It felt electric. He didn't want to let her go. "Having fun?" he asked.

"Yes. How about you?"

"Eeyup. I am now… eeyup."

She looked at him and smiled. Her big purple eyes were glistening. She winked. Big Mac winked back. He turned his head to keep his eye on her as he went to cut the cake.

Scootaloo was given the first piece of cake, much to Apple Bloom's disliking. Big Mac wanted to ask her if she wouldn't mind eating it off his dick, but he held back and watched her eat. He loved the way her tongue moved around inside her mouth while she ate. When she took a bite, she stuck out her tongue and licked the frosting off her lips. Her lips were soft and supple.

She looked up and noticed Big Mac was watching her. She blushed and smiled, and winked again. Big Mac watched intently as she put the cup to her mouth and drank punch… loving the way she swallowed.

When all the filllies were nice and high on cake, ice cream, and soda, they went outside to play. Big Mac followed and sat at the picnic table, not taking his eyes off Scootaloo.

He noticed that she kept turning around and licking herself, and it drove him crazy. Upon closer inspection he noticed her vulva was swollen and then it hit him: she was in heat. This had to be her first heat, coming in much, much earlier than the other fillies. No wonder she smelled so incredible! He kept a close eye on her, trying not to get aroused when she licked herself. He wondered if it felt good when she ran over her pussy with her tongue. He wondered what it tasted like.

He decided, right then and there: he was going to fuck Scootaloo — with or without her consent. With would be easier, but without might be more fun.

The party wound down and everyone left as quickly as they'd come — everyone except Apple Bloom's comrades, Sweetie Belle and Scootaloo. The three girls went up to Apple Bloom's room just as they always did. Big Mac stood outside the door and listened in.

"Something's happening to my body," Scootaloo said. "I'm all swollen down there and my boobies hurt." As Scootaloo didn't have a mother to explain what was happening, Sweetie Belle took on the role. She explained to Scootaloo that what was happening to her was completely normal and it meant she was becoming a mare.

"Your body produced an egg!" she announced. "And it's waiting for a Stallion to come along and fertilize it."

"Why?"

"So you can have a foal!"

Scootaloo looked down and blushed, embarrassed.

"All girls do it," Sweetie assured her, "it's just a natural part of being a girl. It means you're becoming a mare."

Scootaloo never thought of herself as a mare, she barely thought of herself as a girl. She certainly didn't act like a girl, except for the fact that she kind of liked Snails. She reached back and licked herself, this time spending a little more time down there, using her tongue to make long, attentive strokes.

Big Mac was getting hard. He had to go take care of himself.

*

Scootaloo came into Big Mac's room. She was staring at him with sexy, delicious, intense eyes. "I saw the way you were looking at me," she whispered. "Do you want me?"

"Eeyup."

"I want you too."

Scootaloo pressed her lips against Big Mac's. Her lips were so soft, so plump and juicy; her breath delicate and sweet. She gently explored his mouth with her tongue, running it over his teeth and tongue, their spit intermingling with each other. She ran her tongue slowly down his body, all the way to his balls. Very gently she took them in her mouth, moving them from cheek to cheek while stroking his dick with her front hooves. His balls were starting to warm up, and his dick couldn't get any harder. She put the tip in her mouth and licked it like a sucker, sticking her tongue in the hole and swirling it around. A tiny bit of cum came out and she licked it up, running her tongue up and down his hard shaft. She opened her throat and took his length, sucking on it while it slid inside her.

She moaned, and the vibration on his dick was fantastic. He gently fucked her throat while she rubbed his balls. She inserted her hoof in her pussy to get herself started, then frantically shook her head with his dick down her throat.

She straddled him and sat on top of him. She positioned her nice wet pussy right over his throbbing member. She teased him, pushing her pussy down just past the head, rotating her hips, and introducing him to her wetness, but then pulled away, only to return to take a little more length inside her, until finally she bore down on him and started to grind. She was warm, wet, squishy, and so, so tight. Her young, virgin pussy hugged him; it was almost too small, but he figured he could stretch her out a little.

She sat down on his dick and rode him, pushing back and forth, feeling his hugeness moving inside her. She pushed her kegel muscles and squeezed him from the inside and she rocked back and forth on him, her wetness dripping down his balls and past his anus. She smelled so good. Her sweat, mingled with the heat pheromones, made for one phenomenal scent.

As he penetrated her she rode him hard. Unable to get enough of him inside her, she bore down on him and swallowed his entire length in her hot pussy. She put her front hooves on his chest and pounded on top of him, pushing and pulling on his dick so hard he thought she was going to tear it off. She was so hot and bothered, she just couldn't get enough, and she rode fast and hard, while he rhythmically slid inside her. The sound of their skin slapping together was almost too much for Big Mac — he could feel his balls getting hot, and Scootaloo helped him along by caressing them while she fucked him. He started to get stiff all over.

"I'm going to come," he gasped.

"So am I."

Scootaloo slowed her pace and was still as she was delivered, milky white fluid running down her pussy, down his dick and balls, and dripping onto the bed. She sat up straight and trembled while she came, squeezing him tight from the inside as he came too, squirting so hard inside her he thought it was going to come out of her mouth.

*

When he woke from his dream he was still hard, Scootaloo's pungeant scent still fresh in his memory.

"It's on now," he said to himself. "I'm going to wreck that filly."

The next day Big Mac went down to the school and waited for Apple Bloom, who was pleasantly surprised to see him. "What are you doing here?" she asked.

"I just felt like walking you home," he said, and smiled when Sweetie Belle and Scootaloo came to join them.

He walked slowly behind the girls, who were giggling and running and playing around. He savored every second of Scootaloo alluring scent. He watched as she pushed off on her scooter. Her back legs were strong and muscular, as were her shoulders and back from holding on. She winked again. He winked back.

She stopped to lick herself and was visibly embarrassed that Big Mac was watching. A tiny drop of secretion fell from her chin, and she licked her lips, looking up at Big Mac with a red face.

She winked at him again.

He winked back at her, and she turned her head bashfully.

Big Mac walked Sweetie Belle home, took Apple Bloom home, and then walked Scootaloo home. It occurred to him that he had never seen her house, or any parents for that matter. The truth was, he never really cared — up until now.

Scootaloo made small talk with him on her way home. He could tell she was a little nervous — she'd never been with him alone: she always had Apple Bloom with her.

Big Mac didn't show any interest in anything she was saying. He just nodded and said, "Eeyup," counting the seconds until he'd be able to put his dick in her and wreck her. The sooner the better.

She led him to an old, abandoned-looking, dilapidated house and stood on the front porch. The house was dirty. It was falling apart and desperately needed painting, and the yard was unkempt and overgrown. "This is it," she said, obviously embarrassed.

"Where're your parents?" Big Mac asked.

Scootaloo looked down, teary eyed. "Th… they left. One day I woke up and they were gone. They didn't leave a note; they didn't say goodbye. They just left and have never come back. Nobody knows I live here all alone. Nobody except for you."

Perfect.

"Can I come in?"

"Of course you can! I think I have some lemonade, do you want some?"

"I'd love some."

They went inside. The house was dark, dingy, and messy. It was obvious she lived here alone — it looked like a kid's place: stuff strewn everywhere, food left out, dishes all over the place, stains on the wall and carpet, and unpleasant smells coming from unknown sources. The sink was full of dishes and cups, half full of water, the soap dripping onto the floor. There were blankets and pillows all over the place, as if she couldn't find a good place to sleep and had tried every corner of the house. Sad, really, but very convenient.

She went to get the lemonades. He watched her, studying her form and admiring her body.  She was filling out in all the right places. Her rump had gotten just a little bigger: it looked soft, nice and squishy, and velvety. Her nipples had gotten even bigger then yesterday; they looked full and firm. Her vulva was definitely swollen; ripe as ripe could be.

She gave him his drink and smiled at him and winked. He winked back and took a drink of his lemonade. "This is good, Scootaloo," he said. She looked at him funny: he never called her by her name — he always called her 'kid' or 'Scoots' or 'small fry', but never by her name.

"Thank you," she said. Her eyes sparkled. It was obvious that she didn't receive many compliments from anyone. "It's nice to have someone over. I never have company. Sometimes I get lonely."

Big Mac started to get hard. It was almost time.

He finished his drink and stood up, pretending to get ready to leave. "Do you have to go?" she asked. "You could stay a while… if you wanted to?"

He just stared at her. She winked again, and he winked back. "I keep doing that," she said. "I don't know why but lately I keep 'winking'."

"You mean to say… you're not winking… at me?"

"No! I mean… yes. I mean no. I—"

Big Mac walked over to her and stared at her. "You've been teasing me for two days."

She gasped. "What? No, I mean, I haven't been… I'm— I mean, I don't mean to… I—"

"Yes, you have."

She backed up against the wall, Big Mac right up against her. "Big Mac… I–I didn't mean to. I mean, I'm having my f–first heat and I—"

"I know what you're going through. You've been prancing around and holding your tail up to me. You've been winking at me and… teasing me."

Scootaloo's eyes started to fill with tears. She crouched down and looked at him with fearful eyes. He pushed her up against the wall and grabbed her head in his front hooves and slammed her head against the wall. He pulled her lips to his and thrust his tongue into her mouth, breathing hard and heavy. She tried to pull away but he tightened the grip on her head.

"Big Mac," she protested, "please! I–I… Pl—"

He kissed her again and pressed up against her. He was getting good and hard, and started to rub his dick on her belly. Scootaloo couldn't help noticing that his dick was massive.

"I'm going to give it to you," he whispered. "You want to fucking tease me? You'll get what's coming to you." He stuck his tongue in her ear, licked her face, then put it back in her mouth. Her little mouth was hot and sweet.

She closed her eyes as he kissed her. How could this be happening? He was like a big brother to her — how could he be doing this to her?

He ran his hoof down her body. She was trembling. Hopefully she'll still be trembling when I'm inside her, he thought. That would feel wonderful. She was tiny next to him. She buzzed her little wings and he grabbed hold of them, stretched them out as far as they'd go and pinned her up against the wall. She tried to get away again, and he slammed her so hard against the wall she coughed.

She started to cry. "B–Big Mac, pl–please, please don't—"

"Don't what?!" He ran his hoof gently over her face. "Don't what? You think it's funny to tease me for two days and then cry when it's time to deliver?! Now shut the fuck up, Scootaloo. Shut the fuck up and take what's coming to you!"

"P–Please! I'm sc–scared."

He pulled her back and slammed her against the wall again, and got right in her face. "I thought I told you to shut the fuck up," he roared.

She choked back the tears and sobs. Her little body was trembling and shaking all over. Big Mac frantically looked around the room and his eye caught a barstool in the corner, that she'd used to stack dishes on. He reached for it and all the dishes went crashing to the floor. Holding onto her with one foreleg, he positioned the stool in front of her and forcefully bent her over it. He reached into his saddlebag and pulled out some rope which he used to tie her front legs to the stool's legs, then stood back and admired his prize.

He pulled out a long, black whip from his back and cracked it on her ass. She jolted and tried to wiggle free but he'd tied her tight. She wouldn't be getting free — not any time soon.

"This is for you, because you're a bad, bad girl — teasing the boys like you do — I'll teach you to tease ME...you're getting a spanking." He cracked the whip on her ass again and again, raining down vicious strikes that left red marks on her behind, and made her cry and jump with each one.

This was making him intensely horny. He put his dick up against her mouth, and stroked her face with it, running his hoof through her short mane. He put his dick between her lips and whipped her again. "Don't even think about biting me," he said. Scootaloo cried as she took his length into her mouth. Her tears dripped down to his dick. She could taste their saltiness as he thrust it into her mouth. He held onto her head as he pushed his dick down her throat. When she gagged, he whipped her again. "Keep still," he said. "Keep still or get it again."

She held perfectly still, trying not to gag, breathing through her nose, trembling and crying.

He ran his hoof down her back. Oh Celestia, she smelled so good. His dick was so hard he thought it was going to explode. He pushed it down her throat, holding her chin in his hooves to control how wide he wanted her mouth to be open.  He loved the way his dick felt as it slid on her teeth, and her bubblegum tongue.

He lifted up her head and wrapped his forelegs around her neck. She started to gasp for air, and tried to flail her legs but they were bound tight. Big Mac thought it was quite comical to see her struggle so desperately. He looked into her eyes as he choked her. Her eyes were panic-stricken and her mouth filled with his dick.

Her little heart was racing a million beats per second. She felt herself getting light-headed as he cut her air off. She felt dizzy, saw stars, and eventually passed out. When she came to he was standing behind her, spreading her cheeks apart. "That was sexy," he said of her choking episode. "That should have gotten you good and ready."

Savage need completely consumed him and he rubbed his huge cock over her swollen vulva. She was ripe — as ripe as could be. "I'm going to fuck you hard and put you away wet," he whispered. She thrashed her head around and started to scream.

Big Mac shoved a dirty dish towel in her mouth to muffle the sound, and cracked her with the whip a few more times. She closed her eyes tight. Her back and her behind were raw and stinging.

Big Mac mounted her and grabbed onto her mane, yanking her head back. With all his might he penetrated her virgin pussy, feeling her hymen break, feeling him literally stretching her out as he entered. Her heat cycle allowed him to enter with very little resistance, but she was still tight — her young virgin pussy was small, wet, and warm, and hugged him snugly. Just as he'd hoped for, she was trembling all over, making it like a vibrator squeezing him. He held onto her mane, yanking her head back with each thrust inward, savoring every second of his conquest. He watched himself pull it out, then push it back in, getting wet from her virgin marecum and watching it drip down onto his balls.

Slowly, rhythmically he fucked her, letting his balls slap against her ass, rubbing them with his front hoof and grunting with each push in. He whipped her ass while he rode her hard, smiling amusedly at her efforts to get free from his strong hold.

He stopped to savor, his dick deep in her pussy, and revelled in this moment.

"You like this?" he asked her. "Is this what you wanted?" He didn't wait for an answer, but thrust inside her with a vengeance, filling her tiny body with his masculine stallion essence. He stood on his back hooves and pushed his cock in as far as he could, completely teeming her small little pussy. He started to pound inside her. She held her eyes closed, and tried not to focus on the pain — it felt like he was ripping her in half. Brutally and savagely he hammered inside her, striking her with the whip with absolutely no mercy.

Suddenly he stopped. He just… stopped. Scootaloo wondered if it was over and held her breath. She felt him pulling out of her and she breathed a sigh of relief, but quickly stiffened up when he thrust his cock into her ass. "Oowweee!" she cried, wiggling and jostling about, causing the barstool to tip and almost fall over.

"Oh…" Big Mac moaned "Oh this… this… is it." He pushed himself inside her, and rubbed her pussy with his hoof, sticking it up inside her. The friction of her tight ass against his throbbing dick caused him to cum quickly, and when he felt the warmth in his balls he ruthlessly nailed her hard, brutally, viciously holding onto her mane, bending her head back, until with an explosion he finally came in her ass, and watched the milky white fluid run out onto his dick and balls. He yanked her head back one last time and pushed her forward so she fell over, still tied to the stool, looking like a rodeo pony in a roping contest. He picked up the whip and cracked her ass one last time as he smiled.

"Mmmmph," was all she could muster.

Big Mac shook his dick off and went to untie her. He pulled the rag out of her mouth and put his mouth up to her ear. "You didn't see me today… you hear?"

Scootaloo nodded. "Y–Yes."

He untied her and she quickly curled up into a little ball in the corner, sobbing, crying, and trembling.

Big Mac went and sat down next to her and gently stroked her with his hoof. "What's the matter?" he said softly. "You didn't like your first sexual experience?" He thought her first heat had gone very, very well. Just as it did with Applejack’s.
