Chapter 1
The young Twilight Sparkle woke up to sounds of her mother moaning, her parents had an active sex life so hearing moans from her parents' bedroom was not unusual, but they usually only happened at night and were usually accompanied by animalistic sounding grunts and groans from her dad as well which weren't present this time.
Twilight was too shy and embarrassed to ask her parents what was going on, but took comfort that whatever they were doing sounded like it felt good, but these moans sounded like her mother was in pain.
When Twilight tried to get out of bed she noticed that she felt unusually hot, almost like she had a fever. She looked in the mirror near her bedroom closet to notice that her face was flushed and felt an unpleasant dull/burning ache below her waist. Twilight felt sick, but not the usual kind of sick and would normally have stayed home, but today was the first day of "Family Life" classes at school.
She may not have known what it was but knew it was important, since both her parents had to sign a special permission for, and it was her duty as a good student to at least show up the first day.
In her rush to soldier on though she was met with an unwelcome surprise.
"Oh no, I can't believe I wet the bed, 2 years of hard work ruined." Twilight panicked as she noticed a large wet spot on her sheets.
As Twilight went up took the sheets off her bed, she noticed a particular smell, she couldn't place it, but knew it wasn't pee. It smelled oddly familiar, a bit like her parents room smelled one afternoon when Twilights father came home early from work.
Fortunately for her, Twilight always kept a spare set of sheets just in case of such an emergency, and after she was done with that task she got her lunch, backpack, and numerous checklists and headed out the door.
As Twilight made her way to class she noticed multiple mares with uncomfortable looks on their faces, some making similar moans, and groans to her mother and icepacks between their legs. She immediately remembered this conversation she had with her father a year ago when he told Twilight that when mares reached a certain age they went through a "yearly sickness" where the only cure was to use an ice pack and wait it out.
"Do I have this sickness? I feel strange, almost like I have an itch down there, but it is unlike any itch I have ever had." Twilight thought to herself.
As Twilight got closer to the school, she noticed more mares, some of them didn't have ice packs though. The ones without ice packs had swollen vagina's, some even bright red and all of them appeared to be leaking some kind of fluid.
"Is this why I wet the bed? Maybe this is a side effect of that yearly sickness?" Twilight wondered to herself.
Twilight saw a puddle of water as she was walking, and noticed her young pussy was in a similar condition as the mares. She began to blush profusely as her young fillyhood leaked like a faucet with her intense need and was forming a trail in the streets. There may have been plenty of other mares creating just as much of a mess and some even more so, but she still felt a small pang of guilt.
As Twilight brushed her hoof over her lower lips to wipe some of her juices, she let out a load uncontrolled moan as she felt an unexpected jolt of pleasure only to notice more juices starting to seep out. As much as Twilight loved that sensation, whatever it was, she resigned herself to the fact that now was the time or place to explore it. She was a good filly, and only naughty fillies rubbed their crotches in public.
As Twilight continued her walk, she began to notice multiple colts and stallions with erect penis's, some small and some much larger. She knew since that one day she first saw her brothers penis that it wasn't polite to stare but as Twilight got wetter and wetter as her slick folds cravings got more and more intense. As Twilight became lost in her newfound fascination for stallion cocks, she felt that familiar jolt of pleasure.
"Oh my Celestia..." Twilight interrupted herself as she put her hoof to her mouth to silence her uncontrolled moans.
As she looked down to her other hoof she noticed it was between her legs gently rubbing her lips. Twilight wanted to stop but couldn't as her rubbing became more frantic. She felt a floating, almost out of body experience. Going up and up as she her pleasure mounted toward her inevitable "crash".
"Oh Celestia, oh fuck..." The young filly blurted out as her pleasure consumed her. She had no idea what the word meant, but learned it from overhearing her parents often impassioned love making and something about it seemed appropriate.
Twilight was way too involved in her self-pleasure to notice the mixture of aroused, shocked and disapproving looks as they watched what she was doing. Twilight felt flushed and light headed, but in a good way. Twilight's breathing became more labored, her heart beat faster and faster as she felt something coming, she didn't know what it was and only relied on her base instincts as she hoofed herself closer and closer to orgasm.
Her little legs began to shake and fillyhood clenched, her hoof moved rapidly as she shamelessly satisfied her young pussy. Twilight could no longer hold back her screams of pleasure as the tension she felt finally released as she finally began to cum, a copious amount of juices covering her hoof and leaked onto the floor as Twilight collapsed.
"I don't know what that was, but it felt amazing I didn't know my own hoof could do that." Twilight mumbled to herself.
She sat for a minute basking in her afterglow when she heard a familiar voice call to her.
"Twilight, what are you doing?"
Twilight felt a sudden sense of shame and dread as she tried in vain to cover up the evidence of what she had done.
"I am sorry Cadence...I...I..." Twilight tried to explain as she was on the verge of tears.
Cadence looked on to Twilight pulled her in for a hug and said.
"It is okay Twilight, what you did was perfectly natural, and is something most young mares and stallions do."
"I don't even understand what happened, I got this weird feeling you know down there and I just started rubbing it felt good, I didn't want to stop, and..." Twilight tried to explain as she was interrupted with
"Ssssshhh! It is okay, you are going through your first heat, and if you promise to only do that in private from now on; I am going to teach you everything you need to know about why you are having these feelings, and how to deal with them appropriately."
"I need to get to class now, it is the first day of Family Life I will see you after school and my daily magic lessons." Twilight smiled as she tried to trot away.
"Wait Twilight, I can teach you all that myself. I took so called Family Life when I was your age and they barely told us anything." Cadence explained to Twilight.
"But, aren't teachers usually right?" Twilight asked a bit confused and surprised.
"Sometimes, but a lot of adults are a bit squeamish about this subject, and many of them though they are well meaning sometimes shield young fillies and colts from this stuff much to their detriment." Cadence explained.
"But if it is as normal as you say than why do they do that?" Twilight asked as her hoof scratched her head.
"Because many of them see it as similar to using the bathroom, and is some ways it is, but in other ways it is completely different. I will tell you what, you can do both, and decide for yourself which one you like better, consider them extra study sessions." Cadence smiled at Twilight.
"Okay, I suppose there is nothing wrong with a little extra credit, and I do have a lot of questions." Twilight blushed a bit at her admission.
"Don't be embarrassed, before we get you to class though let's get you cleaned up, and get you an ice pack." Cadence suggested.
"Okay, thanks, you are the best." Twilight feeling a bit relieved.
"It is no problem Twilight, everything will make a lot more sense once you complete my program." Cadence smiled at Twilight as she pictured her "lesson plan" in her head.
