While some might call it vanity, Sweetie Belle liked to think she was just more self-care focused than her two cohorts. While Scootaloo's main focus was whatever was cool and Apple Bloom's sassy but level headed approach to life was good for solving practical problems, Belle's somewhat rocky relationship with her older sister had given her a better understanding of how to present yourself to other ponies. Shampoo and brush your mane every day. Always wear clean clothes (especially underwear). Make sure the cut of your clothes work with your body shape properly. If you're going to wear perfume, do so sparingly. She didn't actually have any perfume yet, but she still knew the basics of how to use it.

And while Belle wasn't able to fully process the reasons why, her undeveloped yet knowledge-hungry 13 year old brain picked up on one crucial detail that Rarity seemed to know more about than all of their other role models: boys. Boys were important. Rarity talked about them. She read magazines about them. She watched movies about them. Aside from fashion it seemed like Rarity's other hobby was the opposite sex. Scootaloo and Apple Bloom weren't interested in Belle's blossoming concerns about what boys thought about them but for Belle there was no bigger thrill than listening in on Rarity's hushed conversations with her friends and hearing half-whispered words about...things.

She didn't know what any of the words meant but she knew she liked hearing about them. Out of all the unknown secrets of the grown up world the interactions between stallions and mares (and the gossip around those interactions) piqued her curiosity most of all. Every new tidbit of information related to something-jobs or sucking on things caused an electrifying tingle of excitement to crawl down her body before making her a bit lightheaded.

Unfortunately, despite what Belle considered to be a greater-than-normal amount of knowledge about these things for her age, she just couldn't explain why she liked swallowing cum. It certainly wasn't the taste, which was bitter and frankly quite gross. It wasn't the texture, which coated her throat in an unpleasant stickiness. Her neck and back muscles got an uncomfortable workout when she gave blowjobs. There was objectively no reason to enjoy the sensation of a cock squirting shot after shot of bitter and sticky fluid down her throat, and sometimes even her face and clothes.

But Sweetie Belle loved it. Especially because it involved Big Mac.

This time was no different. Even as his well-endowed cock kept bumping the back of her throat, making it difficult to breathe, that exotic and exciting warmth that only stallions could bring seeped through her body and right into her bones. His hushed and strained moans only spurred her on further, a moan of pleasure coming from her that hummed around his cock as she kept a steady rhythm of bobbing her head back and forth. She could tell now. He was close.

The wet sounds of her mouth around his cock got louder and sloppier as she picked up the pace. After doing this about a dozen times she had figured out he liked it when she sped up and pushed her throat even harder against the flared tip of his cock. She fought against her gag reflex and body's need for air as she could hear Big Mac's breathing get more sporadic above her and his strained grunts echo quietly in the barn they had stowed away in. A lone hay bale in a secluded corner had been the perfect spot -- if she sat on the bale her head was at the perfect height to reach Big Mac's cock if he stood in front of her.

Then the moment she had been waiting for came. Big Mac placed a hand on the back of her head and gently squeezed as he came. Like all the other times before there was no force in his touch. He wasn't forcing her head down or anything...but on her own volition she pushed her head forward so the tip of his cock was pushing against her throat. Her face scrunched up and she gave out muffled groans of exertion as she worked hard to swallow all of his cum. It wasn't easy but she was willing to try.

His labored breath and whimpers of pleasure were her true reward as she gulped down shot after shot of his cum. Every gulp caused the stars through her closed eyes to get more and more intense. Eventually she had to pull away, holding his cock up and towards her face as she gasped for air. By the time she had caught her breath one or two small spurts had landed on her face. Better her face than her clothes, though. Last time he had gotten a stream of cum on her dress and that had been a real chore to clean up and hide from her friends.

Belle moved her head forward and slid his cock back into her mouth, gently suckling at the length as she slowly took it in. She looked up at Big Mac and savored the expression on his face as she sucked the rest of his cum down before swirling her tongue to clean off any remaining traces. It only took a few times to learn that right after stallions finish cumming they get extremely sensitive. It had become a new game of hers to see how long she could keep his cute whimpering and scrunched up, almost pained expression on his face until he was forced to pull her away.

That moment came soon enough and with one last shaky breath Big Mac grabbed her hair and gently pulled her away from his cock. He looked down at her and their eyes locked as his cock slid out of her mouth with a lewd slick sound. They sat there for a moment, looking into each others eyes, as they both softly panted and recovered from Belle's scandalous ministration. Belle gulped nervously and trembled as the moment lingered. Her body trembled as she could feel it call out for something she was having a hard time placing.

Big Mac broke the silence by taking her cheek into his massive hand and gently stroking it with his thumb.

"Good girl."

His quiet, almost growling bit of praise caused her to shudder and she rubbed her head against his hand affectionately. Big Mac wasn't a pony of many words but he knew just what to say to her to send tingles down her spine. He made her feel special. That feeling only grew as he stroked her cheek once more before wiping off the small bit of cum on her face and giving her a smile. Without another word he stuffed his cock back into his pants, stroked her head, then exited the barn.

Sweetie Belle closed her eyes and took in a deep breath and ran her fingers through her hair. Not only did that help smooth out her messy hair, it also helped calm her down. These secret trysts had started to leave her more on edge. She liked touching Big Mac. She liked sucking on him. She wanted more. But she wasn't quite sure what that would be. The only reason she even knew what Big Mac did was called "cumming" was because he told her.

After the first time she had caught Big Mac, alone, in the barn, with his pants around his ankles and his hand around his cock, she thought that would be her pathway to finding out more about the adult world. She had threatened to tell on him at the time, something she still felt a little guilty about. She hadn't known exactly what he was doing but from his panicked expression she knew he shouldn't have been doing it. He had been embarrassed and a little angry but that leverage was enough to at least convince him to let her watch as he stroked himself. Being young and impatient she had escalated the demand to stroking him off herself and with reluctance he had let her small, young hands bring him to orgasm. She gasped and watched in excitement as thick ropes of cum came out of him and splattered to the barn floor. Cool!

However, her part in the act had ensnared her to the same embarrassment and secrecy that Big Mac had shown when he got caught. He let her know, in his usual succinct way, that if anyone found out about this they would both get in a lot of trouble. They should pretend this never happened and never speak about it again.

But that experience had lit up the underdeveloped part of her brain that usually only got stimulation by listening in on her sister. She was curious. She wanted to know more.

Knowing that both her and Big Mac would get in trouble made it difficult to research about what she had experienced. The library was no help. Even the books that seemed like it might be about stallions and mares were full of boring words that too advanced for her to understand. She couldn't ask her friends for help. All the adults she asked evaded her questions and even turned it back on her -- why was she so interested in stuff like that? She had learned to stop asking adults after a few times of trying to lie about just wanting to know because she saw it in a book somewhere.

All the empty roads had led her back to the one place she might still get answers. Big Mac. The next time they would meet came after a day of stalking him and waiting for him to go into the barn, alone. She had snuck in after him and asked him to explain about what she had seen last time. He had protested, weaker than the first time, but she eventually wore him down. He explained that what he was doing was "masturbating" and after you touched a stallion enough he would "cum". A bit of confusion arose when he also explained that what came out when he came was also cum, and that "to cum" is different than just "cum" itself. She got the message after a few clarifications.

And then exactly what Big Mac had been dreading happened. Sweetie Belle if she could touch him again. Real quick. Just one more time. He gave an annoyed sigh but relented with little pressure. Okay, he said. Just one more time.

That turned out to be a lie. After that Belle made it a regular habit of finding him alone when she had time. With each visit his reluctance diminished and soon enough they established a routine. Belle would find him, look up at his large frame with an expectant expression and a bite of her lip, and they would sneak away somewhere. Handjobs gave way to blowjobs. She had even gotten pretty good at unzipping his pants and pulling out his cock herself. She had been pretty proud the first time she did that and he gave a shuddering breath of excitement in response. He was the biggest, strongest pony she knew and she was able to make him excited like that.

She giggled with excitement and got up from the hay bale before skipping back towards the clubhouse to meet up with her friends. She couldn't wait until the next time she was able to meet up with Big Mac.
