A day without work gets even better when you can share it with someone you love. Couples like Rainbow Dash and Hard Knock lived by that mantra and practised it as often as possible, but Berry was the exact opposite in that regard. She cherished quality time for herself and was vocal about it to Big Macintosh, who could understand her wishes as an introvert himself.

One of those personal days had just started with a late awakening at 10am and plans for a quick run through town for greasy hayfries and a cookie milkshake. Luckily, the fast food joint in Ponyville hadn't followed the nationwide trend of serving healthier food. In her honest opinion, If you want salad and apple slices, don't go to a place with twelve different sources of sugar in a single burger.

Hunger for saturated fat drove her out of bed. On her way out, she saw something strange in their guestroom; Scootaloo, the annoying attachment to her brother's marefriend, sat straight as a stick on a chair with a thousand yard stare at Hard Knock's door.

"What are you doing here?"

Scootaloo flinched as Berry came into sight. Where Berry thought Scootaloo was annoying, the filly had not the best opinion of Hard Knock's weird sister either.

The two only tolerated each other for their loved ones.

"Are they in there?" Berry asked, getting a reaction in form of a nod. She entered the guestroom halfway to take a glance at the clock on the wall and felt a sudden tingle in her nose. "Sounds about right. The freeloader always comes straight here, emptying our fridge and stock of cider."

They were busy doing the dirty deed, showed by the white sock on the doorknob. The Berry siblings didn't have much in terms of rules, but the simple piece of clothing always had functioned as effective deterrent for bothering the other during sexy time. They hadn't used the sign for a long time, due to neither of them having a date worth bringing home.

"How long are they going to be busy, Mrs. Berry?" The filly squirmed when the grumpy mare rubbed her muzzle.

"Who knows? Depends in what mood Rainbow Dash is today. My brother is whipped for her whims and... Why is my damn nose so itchy?" Berry licked her dry lips to wet them. She shuddered and gagged from the aftertaste that entered and hit the back of her throat.

A faint, sickeningly sweet odor hung in the air, getting stronger and stronger with every step further into the room. The well-trained nose of this mare couldn't let this attack on her senses slide. Three quick sniffs around the bed pinpointed the source.

The filly in the chair.

"Ah..." Berry responded with a surprised but knowing look, making Scootaloo whimper and put her tail between her hindlegs.

"It's not me... I don't stink... I don't..."She tried to get up and bolt for the door, but two hooves grabbed her by the barrel. Berry had moved with lightning speed, taking hold of Scootaloo and letting herself fall back on the bed.

"Let me go!" Scootaloo yelled and struggled against the hold with an impressive strength for a pony of her size.

One of the flailing hooves hit Berry hard in her left eye and the mare hissed in pain through gritted teeth. "It's ok. You are ok. This is normal! How you feel is normal!"

The thrashing stopped. "You know what it is?"

Berry knew very well. Her earlier surprise came not from its existence but the source. If the other pony in the room had been older, she could have connected the dots much faster. The smell wasn't difficult to recognize although it varied in intensity and it seldom appeared in fillies this young. One mare had a sweeter note, the other had more spice in her fragrance, and all of them had the underlying thick musk.

The lingering scent of a mare in estrus.

"Since when?"

Berry had only a rough estimate of her age, an unfortunate side effect of never bothering to get to know the filly. Given her size and demeanor, she couldn't be older than ten or eleven. Puberty had hit very early and most classmates wouldn't catch up for at least another year or two.

"It's the third time.." Her explanation came rushed to get it out. "The first one was the worst. During recess at school, Diamond Tiara said I even stink like a loser and all the colts looked at me funny." Scootaloo continued, wondering about the wonky grin on Berry's face. "For the second time, I hid myself in Rainbow's bathroom and told her I was sick."

Three cycles at such a young age? The scent of her estrus wasn't too pronounced yet, speaking for a less severe case and explaining how Berry had missed it earlier. A few heavyweights she knew could fog windows with their vapors.

The kid's odor was pleasant in comparison. "I don't want to become the smelly weirdo of our school..."

The grip loosened and Berry let the filly lay on her belly. "Why didn't you tell anyone? What about Rainbow Dash? Isn't she like family to you?"

"I tried once," Scootaloo mumbled, blushing from the memory. "I told her how their kissing sometimes make me feel all tingly at my crotch. She panicked and dodged my question by flying away with a flimsy excuse. I don't want Rainbow Dash to avoid me because my body is acting gross."

Berry became alarmed from the dangerous train of thought. Scootaloo was an early bloomer and thought something was wrong with her because every pony she trusts handles the topic as a huge taboo. While her friends had no urges beyond childish curiosity, she had to deal with real confusion and nopony to fill in the gaps. The little chicklet held a shitty position to begin with, and shouldn't have to be ashamed for her bodily changes on top.

"Ask me," Berry stretched out on the bed with a yawn and the filly on top swayed with her movement. "You hate my guts already and it wouldn't matter if things got weird between us."

"I don't hate you..." Scootaloo objected weakly and got a soft bonk on the head.

"Don't bullshit me, squirt." Berry drawled for effect, ignoring the flinch against her chest at the last word. "I can see how every time we are in a room together your skin crawls. You don't like me."

"Maybe a little..." Admitting it made Scootaloo squirm, which turned even worse by how little her dislike bothered Berry. The mare had known from the beginning and didn't care. Scootaloo couldn't imagine being loathed to the point of it becoming routine.

"It's Wednesday... " Berry's gaze wandered to the ceiling, before shouldering Scootaloo like a sack of potatoes and jumping off the bed. The quickness didn't leave enough time to struggle on their way outside, let alone to ponder what had gotten into the mare.

And why did she need a ladder?

"We might as well start with the big one. Today you will learn the basics of sex," Berry said and propped the ladder firmly against the wall, the top part reaching just below Hard Knock's window. "I could explain all the nitty gritty details for hours, but it's much easier to show you an example and commentate over the different steps."

The timing couldn't be more perfect. Rainbow had intense stamina training on Wednesdays and didn't have the energy to get too kinky for the poor child. "The offer expires soon. They won't be busy forever."

Scootaloo stood before the ladder akin to a climber at the foot of a large mountain. Answers to many of her questions were a small climb away, but the sudden opportunity made her hesitant. The adults always made a big deal out of sex, trying to shield foals from everything even barely related. In relation, Berry might be crazy and might not have her best interest in mind.

What if she couldn't handle it?

"We can still quit and take it slower."

Scootaloo considered the offer for a moment, then took a deep breath to gather herself and took the first steps up the ladder with determination.

Slow wasn't in her vocabulary.

Berry gave a nod of approval and stayed close behind the climbing filly. "Ponies rarely like it when you watch them have sex. For the sake of our lesson, we ignore that rule for today."

"Won't they see or hear us?"

"They won't have eyes for anything but each other and our windows are soundproof for a reason, squirt."

Scootaloo stopped climbing. "Only Rainbow can call me that..."

"Dodo it is then." Berry ignored the huff of indignation and pushed the filly upwards to take a peek inside the window. "Wonderful, they didn't start yet."

Even though she stood two rungs higher on the ladder than Berry, her smaller size didn't allow the little filly to see just yet. A strong leg wrapped around her barrel and lifted Scootaloo up, holding her tight to prevent falling. Without having to concentrate on keeping balance, she could take her first glimpse through the pane of glass and parted curtains.

Hard Knock was a tidy pony and his room reflected this in a perfect manner. Everything was spotless and well organized, except from two saddlebags on the floor. These items belonged to Rainbow Dash, who was snuggled on top of her coltfriend as they lay together on a large bed.

What Rainbow Dash and Hard Knock were doing wasn't much different from Scootaloo's experience. They cuddled and hugged normal at a first glance although rougher for groping their partner on different places. Particular his hooves fixated on squeezing her butt and thighs while Rainbow nuzzled into his chest and rubbed her crotch into something at Hard Knock's hidden lower part.

The real difference came when their lips met. Instead of a quick peck, they stayed together, building a bridge to each other's mouths.

"They are licking on the inside..."

Tongues rubbed together and almost formed a knot as they struggled for dominance with Rainbow's wish to win showing through her aggressiveness. Hard Knock was no slouch either with the occasional bite on her upper lip, making the mare on top shudder and tense. The touching didn't stop during their kiss and hooves roamed more frantic as Hard Knock peaked in roughness with slaps on Rainbow's flank and her howl of approval.

"She's getting better. Lot's of practice I guess..." Berry had to admire the effort both put into a simple kiss. "Prepare yourself, they enter a level beyond cuddling and kissing."

Scootaloo had seen a penis before, remembering when Snails had forgotten to close the bathroom door at school. The little pecker then had been an unimpressive small tube, not a massive shaft with the size of her foreleg. The dangling sack of skin beneath was bigger too, but Scootaloo knew this regarding stallions. Getting through a crowd of ponies, she often had slipped beneath their legs to get through and bumped into one of these on accident a few times.

Stallions and colts made funny sounds when they get hit there.

"I present to you the best parts of a male if you believe shallow mares. Milky, sticky liquid called sperm rests in the sack and gets through the hole in his shaft."

"What is that stuff good for?"

"The stallion shoots it into the mare and she grows a baby in her stomach."

The secret of new life, dropped onto Scootaloo in the most casual way imaginable.

"I'm simplifying the process heavily. Today's lesson is about the fun part of sex to take away the mysticism and secrecy. Regardless of whether you want to learn more about sex later, you will get another lesson about pregnancy and the risks of motherhood from me. The early maturing of your body makes this not negotiable. It's far too important."

The seriousness melted from Berry's face when Scootaloo nodded. "Good! Back to the lesson. Foreplay is vital for enjoyable sex. If your future coltfriend keeps skipping this portion, dump him as soon as possible."

Rainbow handled the obscene body part with delicacy, stroking and brushing along the texture with the frog of her hooves. It didn't stay at hooves for long as Rainbow buried her face at the base of his cock to nuzzle him and messily lick upwards to the flat tip.

Scootaloo made a face and stuck out her tongue. "Sucking on a pee-pee seems gross."

"It's an acquired taste." The diplomatic answer sounded right to Berry. She didn't get withdrawal from going without Vitamin D, but there was something satisfying in pleasuring the cock of a stallion your sweet on. "Many mares use it as a reward for their stallion."

Scootaloo could make sense from that answer. Rainbow loved Hard Knock and wants to show how it by doing something he enjoys. From Berry's angle, the complicated world of adults became less complicated. Hard Knock confirmed the claims of his sister by leaning back with closed eyes as Rainbow licked his rod.

The earlier statement in relation to privacy during sex made sense too. As much fun as she had, Rainbow looked ridiculous with her mouth pressed against Hard Knock's groin, gagging and moaning over his nuts.

Who would want to be seen this way?

Hard Knock put a stop to Rainbow's oral service and Berry's mouth became a thin line from gritting teeth. "He isn't confident in his stamina today." They watched Rainbow pout at her coltfriend before he lifted and flipped the mare on her back. "He wants to make it worth her while. Watch closely, the real sex starts now."

"I thought she had to swallow his white stuff to make a foal? Where does it go?" Scootaloo asked, just as Rainbow leaned back and spread her hindlegs for Hard Knock to lay on top of her. The large shaft got closer and closer to her entrance and solved the riddle by rubbing her slit that looked so small in comparison. "He's putting that huge thing there?"

"My brother is slightly bigger than average," Berry said with a weird sense of pride. "But the pleasure box of a mare is very stretchable to accommodate a stallion's member."

Soon, Scootaloo was drawn in by the steady rhythm of their bodies grinding into each other, first slow and deliberate, then quicker and quicker with more fervor. "He's moving so fast..."

"That's the main part of sex. Both get satisfaction as the mare envelopes his cock with her warmth and pressure while the stallion fills up the mare and strokes the sensitive insides of her love tunnel.

Rainbow got tossed again, flank raised in the air and face showing her anticipation as he mounted from behind. The suspicion about her brother got confirmed, seeing his expression contort for brief moments in flashes of agony.

Scootaloo noticed as well. "Is he ok?"

"His body is hurting, and the idiot is pushing through the pain for her sake." Plum hooves gripped the ladder and the sound of creaking wood stressed her grim tone. "Remember my advice about dumping selfish coltfriends? The opposite is true here. If you find somepony that willingly makes such sacrifices for you, never let go."

Scootaloo winced as Berry gritted her teeth harder in solidarity to the painful grimace of her brother. The Berry siblings weren't so different on a closer look. They cared deeply for their loved ones and didn't sugarcoat those feelings or tried to hide them.

They continued to watch their lovemaking in silence. The heat between Scootaloo's hindlegs had worsened since she watched and the building wetness made her feel sticky to the touch. One hoof traveled down to the aching spot, touching it faintly before she realized her actions and froze in shock. Scootaloo was about to pull away and pretend it never happened, but a much bigger hoof held hers in place.

"Explore yourself and don't be ashamed of your urges. It's not weird or gross, just intimate and personal. Nopony will see you up here and I don't count, remember?"

Berry wasn't looking at her as she spoke. Instead, she stared blankly into the room, her eyes not focusing on anything and giving the filly relative privacy. Scootaloo was wet to the point of being drenched and Berry got the strongest whiff of arousal up to now.

Small moans escaped after the first careful rub over her small folds. It sounded nothing like the usual scratchy voice, too bassy and smooth from within the throat. The deep, burning itch was soothed, calming the heat as long as she kept rubbing. The slow motion soon wasn't enough anymore, forcing Scootaloo to hunch over and get deep in between her parting lips. Her head flushed in embarrassment from the sounds she was making, but the frantic hoof didn't stop to bring her closer.

"Your body is changing to prepare yourself for sex, yearning to be satisfied and is overwhelming you with its urges. It's a troublesome part of growing up and I know how tempting it is to give in to your temptations. Sex can be a mundane or likewise wonderful thing to share. Don't waste that gift on just anybody, Scootaloo. Know what you want and what you will give to somepony."

"Gah.. Hnng.. Ahhh!" Scootaloo erupted with an unimpressive squirt of sweet-smelling fluid, but it rocked the inexperienced virgin to the core. If she had to describe the sensation, Scootaloo would call it a tingle from the center of her sex to the furthest ends of her feather tips.

"There shouldn't be any problems with waiting for the right pony." Berry had to hold the small body in afterglow to keep Scootaloo stable. "Preferably, try to find somepony you can share with what they have..."

"Do... do you have somepony like that?"

"Maybe..." Berry said with faltering voice before catching herself with a cough. "Pay attention, they are getting close to the end."

Rainbow was flipped on her back again and Berry explained what sex positions were and how the missionary position allowed a couple to stare into each other's eyes. She also could barely hold back from cursing at her brother for straining himself so much to please his mare. The look of pain always vanished when Rainbow Dash changed into a position where she could have seen his face.

Berry had to talk with him soon.

The thrusting stopped with one final push into her depths. Hard Knock trembled from approaching climax, but to the surprise of two spectators and one participant, Rainbow removed him with a quick jerk and dived for the swelling cock. The speedster was just fast enough to close her lips around the tip and let him finish in her throat, sucking for every last drop like a vacuum. Her cheeks bulged and Hard Knock gave a small push to free his member, spraying the sticky liquid all over her face with a look of pure satisfaction.

Scootaloo got a tap on her shoulder. "That's the gist of it. Let's postpone advanced stuff for now."

"But it still itches..." Scootaloo pouted, but followed the descending mare down the ladder.

"Of course it does, you didn't do much and doing it only once won't help either." Berry stepped from the ladder and picked up Scootaloo to put her down. "I won't be in my room for the next hour, so knock yourself out."

The smile of the filly could have melted steel. Scootaloo gave Berry's foreleg a quick squeeze before she bolted back into the house. Berry stayed true to her word and remained outside, deep in thought about the recent changes and additions to her life. The little dodo was in her care now, depending on her guidance beyond the occasional sexual advice that Rainbow got to spice up the bedroom. In the shaking hooves of this former drunk rested the well-being and development of somepony else.

Better not mess this up.

Got this out a bit earlier than planned, because I won't have internet on my pc for a while. (My phone still connects, so I can read comments and do small corrections if necessary).

I hope you enjoyed it and I'm looking forward to your feedback.
