Sweetybelle was not the patient type she had been teetering on the edge since last week, after Scooterloo had found that outhouse for her to go pee in. She had thought about nothing else other than what happened that night.

The clock slowly ticked. Each tick reverberated through her pony ears. She thought of nothing other than the lengthy stallions cock, it’s smell still filling her nostrills, the texture of its soft skin against her tongue, the sweet taste in her maw and the warmth of his cum which filling her guts....” Her plot tingled and her cheeks flushed a bright red as she drifted back into reality as she noticed her friends looking at her odd behaviour with raised eyebrows.

Applebloom put a hoof to her chin inquisitively. “Are you okay Sweetybelle? You look like one of grannies prize apples!”
Scootaloo laughed loud “Yeah she has the same look Fluttershy did when she got that lotion on her face helping Harry the bear that time! It was weird it didn’t look like normal lotion!”

Sweety flustered in her seat, she was the only one in the room who knew what Fluttershy really had on her face that day...it all made sense now. Her body ached for cock and cum.
Forcing a reassuring grin through gritted teeth to her friends as each tick of the clock made her plot twitch as her friends laughed around her unaware what she was going through.

Just as Sweetybelle mustered the confidence to ask to be excused the clock bell rang out with it’s high pitch chime. She leapt up from her seat and cheered aloud. Oh how she had waited for this moment all week to come. She ran out the door before her friends could blink. Scootaloo and Applebloom took flight after their friend who was galloping through the open field. Smiling wide as the faster she ran the cooler the wind was against her burning plot. Scootaloo flew down from overhead making Sweetie drive her hooves deep in the turf grinding to a holt.
“Woah there filly, where in the hay you going in such a hurry? Can’t wait for your friends?”
Sweetybelle frowned she felt quite guilty keeping her friends out of the loop, however her sister Rarity had sworn her to secrecy as they had to protect their clients aswell as themselves. She caught her breath as poor Applebloom came puffing over the hill trying to catch her breath.

“I’m sorry girls, my sister Rarity has some...chores for me to do...” Apples and Scoot cut her off shouting in unison. “Don’t worry we’ll help you out!!”

She smiled at their kind gesture and hugged them. “Thanks girls but this ones just for me, my sis is going to be teaching me how to be a lady...you know...like how I was nearly caught short last week?”
The girls stifled a teasing laugh. Scootaloo snorted a laugh. “Say, just ask Fluttershys bear how he goes in the woods!” Applebloom giggled. “Maybe Princess Twilight can tell you how she buries hers with a magic spell!”
Scootaloo stopped short looking in awe at Apples. ”Wait, she really does that?”
Her friends laughed at her this time. “No silly...well at least I don’t think so anyways?”

The three fillies burst into laughter finally breaking the tension. “Okay Sweetybelle, you win. But promise us you’ll meet us at Cupcake Corner tomorrow.”

Sweety smiled “Of course girls, cross my heart and hope to fly stick a cupcake in my eye!” They hugged again before letting Sweetybelle gallop home.

A short time later...

Sweetybelle burst through the door of the boutique huffing and panting was greeted by Rarity.
“Ahh darling your just in time I’ve just prepared a bubble bath for you...”
Rarity turned from her sewing maching and looked toward her little sister over her red framed glasses.
“Hmm and not a moment to soon by the looks of it either. Whatever have you been doing darling?”

Sweety caught her breath back finally able to let her guard down and speak freely about her dilema.
“Oh sis! I’ve had a tingling feeling in my plot all week that won’t go away thinking about last week and what’s going to happen tonight!”
Rarity smiled trotting over to comfort her sexually distraught little sister.
”Oh darling, why didn’t you say something sooner? Sometimes it takes a filly more than her hoof to scratch an itch at times. Every filly has her own way of dealing with her urges. You see darling...Twilight has her courtesans at the palace, AJ has...well...Big Mac, Pinky has Gummy, Rainbow Dash has...Cloudsdales finest or at least says she does and Fluttershy has Harry...”
Sweety looked to her sister “And you sis?”

Rarity blushed slighty a moment. “Well Sweetie darling, I...have one of these” A purple glow emminated from her horn and a phallus looking object floated towards Sweetie.

“Ewww Rarity, I didn’t want to see it!” She cried out.

Rarity huffed rolling her eyes. “This isn’t mine darling, it’s yours. I was keeping it until you reached.. well this age”
They both blushed as Sweety’s horn glowed as she took the phallus from her sister. “Thank you sis.” She said smiling.

Rarity smiled. “Now go for your bath darling before it gets cold and remember not to tire yourself with your new toy, you’ll need your strength for tonight.” She said as she turned back to her sewing machine.

Sweety headed upstairs and jumped straight in the bath. It was full of bubbles and smelled like a candy shop. On the side was a glass of wine with a small tray of chocolates. Sweety felt a warmth wash over her at her sisters kind gesture as she drooled upon seeing her favourite truffle in the middle of the tray. She picked up one of the chocolates and sipped the sparkling drink. “Real wine! Aww sis!” She glowed.

She lay back into the warm water closing her eyes letting go of her carnal reigns, finally allowing her horny mind run free for the first time this week.
She relaxed into the warm water which was slowly lapping at her body with her thoughts wandering over the stallions cock, thinking of nothing but the length and girth of it and how it filled her mouth she thought biting her lip as she thought of those big swinging balls filling her filly belly with cum.
Her cheeks rosied as her horn glowed picking up her new toy up as she caressed her crotch tits with one hoof and her pony slit with the other whilst losing herself in heated thoughts.

She used her magic to transmute the toy phallus into the stallions cock, every part of it was burned into her mind the smell, the taste and the texture she only wished this toy could cum so she could taste him again making her wonder if he would show up tonight. She put her tongue to it only realising the water would wet it up for her. She almost giggled at herself biting her lip as she put the toy to her tender slit sliding it up and down against her waiting plot.

She made a squeak biting down on her lip as she pushed her stallions dick inside her tight pony body. She kept it there a few moments overwhelmed by this new feeling inside her.
Up to now she had only rubbed herself or dry humped a table corner at best, but this was a totally different experience altogether. She focused on this new level of pleasure flowing through her body her mind spinning, her breaths were short and heavy with stars shooting around her vision.

She was in heaven.

Once her body and mind had fused together over this new sensation bringing her one hoof closer into marehood. Taking a deep breath she once again moved the girthy toy cock inside her, moving it to the lapping of the water making her gasp and moan with the new sensations from inside a part of her that she never knew existed until now.

She looked down to watch it slide in and out of her body only to see her belly ever so slightly rising up as the penis went inside her. She stopped suddenly gasped aloud. “What in the hay is that?” Wondering for a moment whether this was normal and if she should continue to her satisfying orgasm and then she remembered Rarity telling her not to tire herself out so laying back into the warm water closing her eyes gently sliding the phallus between her crotch boobs, she moaned out loud as she slid against her tender teats taking her other hoof she rubbed her clit feeling her petals budding she breathed hard and heavy her moans turning into squeaks finally reaching her orgasm.

She threw her head back gasping, succumbing to the wave of pleasure washing over her body. She let herself relax as she drifted under the warm water letting herself go, giving into the pleasure flowing through her body.
A whole week of being sexually pent up just evaporating into the warm water against the cool air.
Coming back up breathing in a lungful of cool air she felt like a whole new pony and was ready for whatever the night would bring her.

Rarity knocked on the door and entered after a moment. “Ahh Sweety darling, how is your bath?”
Sweety smiled. “Ohh it’s just wonderful sis! Thank you for the chocolates and real wine. I thought it was the filly version when I first saw it!.”

Rarity smiled wide pleased that she had done something nice for her sister.
“Well after what you swallowed last week, I don’t think a small glass of wine isn’t going to hurt.” Rarity’s horn glowed reaching through the bubbles for the sponge to rub her sisters back, but instead pulling out the stallions phallus from the suds.

Both ponies blushed. “Sweety did I just pull this out...of...you?”
Sweety went red. “No Rarity it...it was just lying on my belly...”
Rarity was about to drop it back when she got a proper look at it, as the shock wore off. “Ohh my Sweety, this is some...this is some imagination you’ve got.” Sweety used her magic to try and snatch it away but her sisters spells were stronger than hers.

Sweety looked to her sister. “That’s the stallion from last week sis. I’ve thought about nothing else and it’s been driving me crazy not knowing what to do with myself even cloppin’ ain’t done diddly. I’ve just wanted that thing inside me every minute of every day for the whole week...the whole week Rarity!!”

Rarity took a breath carefully placing the toy on the side of the bath, she had thought about dropping it back under the water out of sight however she was somewhat fascinated by it and wanted to look at the fine specimen a bit longer herself.

“Sis can I ask you something and promise you won’t get upset?” Sweety nervously asked. Her puppy eyes looking up at her big sister.
Rarity stood there frozen all of a sudden feeling more like a mother than a sister. “My darling Sweety, whatever could you have done to make me upset at you?” She gasped trying to reassure her sisters emotions aswell as her own.

“Well it’s embarrassing, but you’re the only pony I can talk to about it.”

Rarity gulped trying to keep herself grounded. “Heavens Darling whatevers happened? You can tell me.”
Sweety took a deep breath letting the water wash over her. “Well you see, when I put...that...the new toy inside me and it was feeling good...like really good but I looked down and my tummy was popping up when I pushed it in.”

Silent tears came to Raritys eyes. “Ohh my Sweetybelle!”
Her voice wobbling as she teared up with relief. “My darling Sweetybelle, I forget that you’e not the little filly you once were and are still quite innocent. You have nothing at all to worry about! We fillies are all different too, not just the colts and stallions with their various sizes of cocks and balls. We fillies have different teat sizes, hips and so on. So when a filly has a stallion inside her and she is smaller inside than his member then it can push her belly out with each thrust. Ohhh Sweetybelle I’m so sooo sorry I didn’t talk to you sooner about all this. I’m so pleased that you are alright!”

She grabbed her sister and hugged her tightly forgetting a moment that Sweety was still in the bath but this time it didn’t bother her in the least.
Her sister was more important than anything in the world. Rarity continued hugging her sister. “Are you alright? Did you hurt yourself? I have a spell and some tea that can help if....”

Sweety managed to take hold of her sister. “RARITY! Thank you but I’m fine. I’m not hurt. It just scared me a little when I saw my tummy poking up like that...but before all that it was feeling really good...like really good, you know?”

Rarity smiled nuzzling her nose into Sweety’s wet mane hugging her tight.
“I do know Sweetybelle I know exactly what you mean. Now hows about I wash your mane and we go see some very eager gentlecolts?”

Sweety looked at her with her big bright green eyes. “That sounds great to me sis!”

Author's Note

I wasn’t originally going to publish this due to it only being a short tail inbetween chapters to help me build up the mane story grow.
However I think that it’s just a fun and naughty read to get your juices flowing for the following chapter.

Anyway I hope you all enjoy!
